    the lock function can be activated. It's also easy todrill into the mechanical part to trymanipulate this and thereby activate a locking function forto be able to unlock without a key or with apredetermined lock code to activate a lock function that doesthat the knob does not rapp and you can unlock.
    The object of the present invention is to solve themthe problems with the above-mentioned constructions,by making that locking function difficult to access behind twoimpact-resistant metal plates, which have a round holethrough which the rotary function in the form of acylinder formation, having the knob, is arranged.
    The cylinder formation is rotatably anchored between the twothe metal plates with radially projecting elementsarranged between the two metal plates, whichtamper-proof and rotatably fixes positionthe rotary function.
    Thanks to the invention, a simple one has been achievedcheap, well-functioning and sabotage-prooflocking function, which is difficult to sabotage and activateits locking function, which is arranged at a lockable unit,for example a door, a window, a door, a cupboard, agate, as in rotation, when its locking function isactivated, transmits a torque via a mechanical partto a locking element e.g. a locking piston, a screw connection,to lock from the outside, unlock a space or aenclosure. When the lock function is deactivated, rapthe rotary function and can then not transmit the torque.
    According to the invention, the rotary function has a cylinderor a cylindrical formation axially inserted intoa first round hole a predetermined length inserted through onefirst metal plate located closest to the outside.
    The cylinder formation is rotatable about its own intendedcenter axis. At a distance, about 2-10 mm and behind this, isa second metal plate arranged, together covering itthe mechanical part with its distribution surfaces.
    The mantle surface of the cylinder formation then touchesthe rotation of the edge area of the first round hole, whichradially position-oriented rotary function. Mantelytanexhibits along its circumference / periphery one or moreradially projecting elements, as in the case of rotationmoved and guided between the metal platesinner walls, to position the cylinder formation in positionaxially. The position of the protruding element axially aroundmantle surface, determines the length of how farthe cylinder formation is inserted into the first hole andhow large a length of this becomes visible from the outside. Thethe second metal plate, which is located closest to itthe mechanical part has a second hole, through whichthe end of the cylinder formation can be completed or walkedagainst if the other hole is smaller thanthe diameter of the cylinder formation, to thereconnected to one from the mechanical partprotruding axis of rotation. At a preferredembodiment of the invention, exhibitsthe end of the cylinder formation, facing the mechanical onethe pivot axis of the part, a connecting surface extending transverselythe imaginary center axis, having a long narrow channel,extending into the plant surface, having apredetermined depth. The length of the channel is shorter thanthe diameter of the cylinder formation. The channel provides space for oneelongate element, which is arranged at the end of the axis of rotationextending across the axis of rotation at a clear distance fromthe inner walls and bottom of the long narrow channel, toaddress deformations during sabotage against. the metal plateswithout the elongate member abuttingthe walls and bottom, which would otherwise continue and damagethe rotary function. The connection surface with the channel and thatthe elongate element is then arranged betweenthe metal plates to be position-oriented there by these.
    The distance between the inner walls of the metal plates is,at least in an area which is radially a few mmfrom the mantle surface, approx. 2-10 mm, to create space thereate the elongated element and the protrudingthe element. To further reduce the risk of sabotage,the elongate element is a round rod, which isrotatably radially arranged at the end of the axis of rotation, in one thereexisting recess or hole formation, which allowswhen drilling with a drill through the first metal plate againstthe round bar, this rotates and maneuvers away the drill. INthis position, when the installation surface with the duct is locatedbetween the metal plates, the second round hole has onediameter of about 5-15 mm, which is then smaller than the firstround hole diameter of 20- 70 mm. Rotary shaft diameteris then slightly smaller than the diameter of the second round holeat 4- 14 zmn, which makes the other metal plateinner wall covers, protects the end of the pivot shaft and thusreduces the risk of a piercing towards itthe mechanical part must take place. The cylinder formation visiblepart seen from the outside is shaped like a knob, which is made insame piece as the cylinder formation. Then it stretchesthe mantle surface approx. 1-20 mm with the same diameter out through itfirst metal plate, to make it difficult toaccess with a tool, to pry aroundthe cylinder formation where it touches the edge area, forto try to access the protruding element there, whichextends around the entire periphery of the mantle surface, whichcauses the cylinder formation to become very difficult tomove out of its position. The metal plates are about 0.5-2 mmthick and in a variant of the invention consists of twosabotage protective covers made of sheet steel, laid at a distancefrom and in each other, which are fixedly arranged at itlockable outside of the unit with fastening parts extendingthrough the lockable unit, mounted from the insidethe space and which are thus not accessible from the outside. Forto further reduce the risk of sabotage bythe covers, they connect to the outside of the lockable unitagainst a bottom plate against this underlying plane ofmetal, which is about 1-4 mm thick, made of sheet steel,having screw holes through which the covers are screwed.
    The bottom plate has side edges, which are enclosed by twoof the edge areas of the covers to position the covers in positionsideways at the sabotage. The round holes each show its ownsealing gasket, e.g. an O-ring, to seal aroundcylinder formation and axis of rotation, to avoidwater leaks in from outside. Drainage holes are providedat the bottom of the lower parts of the covers, to ventilate outmoisture from inside the covers.
    The invention is described in more detail below with the aid of someembodiments of the invention, in whichFig. 1 shows a vertical section through a locking functionarranged in the cover with the two metal plates, ona lockable device,Fig. 2 shows a view of a part of the visible part ofthe cover seen from the outside directly towards its outside,Fig. 3 shows a vertical detail section throughthe rotary function in the axial direction,Fig. 4 shows a view straight towards the end of the cylinder formationconnection surface and the first metal plateinner wall, showing the channel with the round bar.
    As shown in Figures 1-3, a tamper protection is shownlocking function 4 at a lockable unit 2, as in rotationvia a knob 19, at a rotary function 1, which transmits onetorque to a mechanical part 3, having arotary shaft 20 when rotating the knob, as for the rotationfurther to the locking function 4 and a locking element e.g. onelocking piston. The rotary function 1 has a cylinder formation5, which is axially arranged in a first round hole 7 ina first metal plate 8, which is arranged at a distance froma second metal plate 13. Cylinder formation 5 mantle surface10 touches the edge area 9 of the first round hole 7 atthe rotation, such as radially position-orientedcylinder formation 5. Along its circumference, exhibitsthe mantle surface 10 a radially longitudinal unbrokenprotruding element 11, to axially position orientthe cylinder formation 5 between the metal plates 8, 13. Thethe second metal plate 13 has a second round hole 14,through which the end 12 of the cylinder formation 5 is axialcoupled to the axis of rotation 20 of the mechanical part 3,having a predeterminable clearance 22 betweenend 12 and end 21 of pivot shaft 20, to receivedeformations in the metal plates 7, 13. The metal plates 7,13 consists of tamper-proof covers 15, made ofsteel sheet, which are fixedly attached to the lockablethe outside 16 of the unit 2 with fastening parts 17 extendingthrough the lockable unit 2. The covers 15 connecttowards the outside 16 of the lockable unit 2 via aunderlying planar base plate 31, which exhibitsside edges 27, of which at least two opposite side edges 27surrounded by at least two of the opposite of the covers 15edge areas 18, in order to fix the positions of the covers against them15 sideways in case of sabotage. The round holes 7, 14 haveeach its sealing gasket against moisture coming from outside. Onedrainage holes are provided in the lower parts of the covers 15,to ventilate moisture from inside the covers 15.
    As shown in Fig. 4, the end 12 has aconnecting surface 23, having a radialextending longitudinal narrow channel 24 with a length which issmaller than the diameter of the cylinder formation 5. Channel 24provides space for a radially extending elongateelement 25, which is arranged at the clearance 22 fromthe inner walls 26 and bottom 32 of the long narrow channel 24.
    The elongate member 25 is a round bar 30, which isrotatably and radially arranged at the end 21 of the axis of rotation20 in an existing recess / hole formation 29, whichmakes that when drilling with a drill against the round rod 30,this rotates and maneuvers away the drill.
