![]() Ratchet wrench
专利摘要:
The invention relates to a hand tool, namely ratchet wrenches, and can be used in various machinery industries for assembling threaded connections. The purpose of the invention is to increase reliability, as well as reduce material consumption and increase the strength. To do this, in the ratchet wrench containing the ratchet insert 4 with teeth 12, the cams 15 are pivotally mounted in the head 2, and the coupling of the cams 15 with the teeth 12 is provided with a curved element 18 with protrusions 19 acting as springs and in contact with the cams 15. When the key with a shed 6 is installed on the nut and tightened with an alternation of workers and idle strokes. 3 hp f-ly, 7 ill. 公开号:SU1611210A3 申请号:SU874202212 申请日:1987-03-13 公开日:1990-11-30 发明作者:Грцанна Курт 申请人:Петер Вольтер (Фирма); IPC主号:
专利说明:
1 one The invention relates to manual. i-THCTpyMeHTy, but also for ratchet wrenches and can be used in various parts of the machine-building dp threaded assembly ™ The purpose of the invention is to increase the rearwardness by eliminating jamming of the cams when the handle is idle, reducing the materiality and, at the same time, increasing the strength Fig „1 shows a ratchet wrench, general view; in FIG. 2, the same axial section; on fig.Z - ratchet insert, general view; in Fig „4 - cam, common V1y; Fig. 5 shows a spring clamping device, the general view; on fi-g, 6 and 7 - key c. the work, the ratchet nut wrench contains an r-body in the form of a handle 1 with a head 2 at the end, having an open annular cavity 3, in which a fea is installed with the possibility of vrtsen snoring insert 4 with jaws 5 forming the open mouth 6 o The key body can be made of two symmetrical. with respect to the axis of the halves 7 and 8, made of metal or plastic and interconnected by a rivet 9, and in its soy cavity 10 a tube 11 can be pressed, which eliminates the possibility of shifting the halves 7 and 8, i.e. strengthens the handle. The ratchet insert 4 (see Fig. 3) has on the outer surface evenly-spaced teeth 12, as well as 13, ensuring fastening and axial fixation of the ratchet insert 4 in the annular cavity 3 of the head 2. At the ends 14 ratchet insert 4 a notch shsh is another similar means d. p facilitate hand grip when returning the ratchet insert 4 to its original position, In the annular cavity 3 of the head 2, the cams 15 are located. They are hinged with the help of racks 16 made on their ends and circumferentially positioned on the head 2 from the vertices 17, in which the indicated racks 16 are placed. FIG. There is Kyjja4KOB 15, but another number can be chosen. Ratchet box 4 and cams 15 can be made of plastic, ceramic materials of other materials, have 11: (their necessary strength. To provide coupling 15 with ratchet teeth 4 0 five 12 Q 0 5 0 0 five ten preliminarily} a clamping spring device in the form of a sheet annular cavity, curved in shape, 3 elements 18 with partially cut out and folded-back flat plates The spring of the springs is the protrusions 19 that are in contact with the cams 15. The bent element 18 is placed in the annular cavity 3 of the head 2 and preferably has a radius of curvature that surpasses the radius of the inner surface of the annular cavity 3, therefore it is adjacent to the wall of the annular cavity 3. under a little effort. The curved element 16 performs a dual role: it ensures the adhesion of the cams 15 and the teeth 12 and increases the rigidity of the head 2. To ensure that the cams 15 are pushed in / out, a small spring force is required, since it is necessary to overcome small inertia forces determined by the mass of the cam 15 , and the strength of friction in the supports. Therefore, when the ratchet insert 4 is rotated, insignificant resistance forces take place, which is especially important at the initial moment of screwing up during the colostrum of the handle 1. The element 18 can be made of steel sheet, bronze or plastic. In order to provide a min1-turn angle when the handle 1 and 1 are idling, different pitch teeth T2 of the ratchet insert 4 and cams 15 are drawn at different pitch. For the key shown in FIG. 1, the angle of rotation of the handle when idling is 10, i.e. after a given interval, the cam 15 and teeth 12 are repeated. The key works as follows. The key can be mounted on the nut 20, thrusting it in the radial direction (FIG. 6) when the throat 6 of the ratchet insert 4 coincides with the slot of the head 2, and when the ratchet wrench 4 is closed (FIG. 7), putting it on the end of the pipe 21. and moving along the axis of the latter, the thrust from the end to the nut 20o The nut 20 is tightened by alternating the working strokes of the handle 1 (turning it clockwise) and the idle strokes (returning to the initial position). In the open position of the ratchet insert 4 (Fig. 6), the key is removed from the ga-ki 20 by its radial movement, and in the closed position (Fig. „7), the key is initially moved along the pipe axis 516
