    An expansion dowel is proposed which has an expansion cone (4) which can be drawn into an expansion sleeve (5), a sliding sleeve (8) of plastic or the like being arranged, according to the invention, between the expansion cone (4) and the expansion sleeve (5). During the expansion process, a part of the sliding sleeve material is crushed by the expansion sleeve (5) over the cone surface of the expansion cone (4), so that the pores of the metallic surfaces of the expansion cone (4) and of the expansion sleeve (5) abutting onto one another are clogged by the material of the sliding sleeve (8). In this way, good sliding characteristics are achieved between the expansion sleeve (5) and the expansion cone (4), and a correspondingly good subsequent expansion capability. …<IMAGE>…

    The invention relates to mechanical engineering, in particular to fastening devices. Known expansion dowels containing a rod with a spacer cone at one end and fastening means in the form of a screw at the other end, placed in a expansion sleeve with the possibility of retracting the spacer cone into it. The expansion of the expansion cone is carried out as follows: the screw rests on the object to be fixed and during rotation draws the expansion cone from the hole into which the expansion plug is inserted. The expansion sleeve is rigidly fixed in the bore. This type of expansion dowel is primarily used for fixing in concrete structures. During operation, as a result of the formation of cracks in the concrete, the hole expands and additional fastening of anchors in the hole is required to securely fasten the object. The purpose of the invention is to increase the reliability of fastening. The goal is achieved by the fact that the expansion dowel is equipped with a sliding guide in the form of a sleeve of easily deformable material with anti-friction properties, the expansion cone on the screw facing side is made with an axial stop, the sleeve is installed on the rod in contact with the stop of the spacer cone and the inner surface of the expansion sleeve and has an outer diameter greater than the diameter of the stop. The drawing shows the connection of parts using the expansion plug dowel. The dowel contains a rod 1c with a spacer cone 2 and fastener in the form of a screw 3. The rod 1 is connected to the screw 3 by means of a threaded connector 4. On the rod 1 there is an expanding sleeve 5, the expansion cone 2 has an axial end facing the screw. stop b in the form of an annular surface. In the section 7 of the rod in contact with the anvil 6 and the inner surface of the expanding sleeve 5, a sliding guide in the form of a sleeve 8 from an easily deformable material with anti-friction properties is installed. The outer diameter of the sleeve 8 exceeds the diameter of the stop, and the inner diameter corresponds to the diameter of section 7. The sleeve may be made of polyamide or of a corresponding synthetic material. A spring ring 9 is placed between the screw 3 and the expanding sleeve 5. The sleeve 8 has a conical outer surface, the taper of which is the same or different from the taper of the distance cone 2. The sleeve 5 is made with a conical surface 10 corresponding to the surface of the distance cone. After placing the dowel in the hole 11 of the concrete base 12 by rotating the nut 13, move the screw 3 with the stem 1 and the spacer cone 2 in the direction of exit from the hole. Since the expanding sleeve 5 is rigidly fixed by means of a safety element - a spring ring 9, the sliding guide sleeve 8 and the expansion cone 2 enter the expansion sleeve and expand it until it is pressed against the wall of the hole with the necessary pressure. When expanding the clamping sleeve 5, a portion of the material of the sleeve 8 protruding in the area of the stop 6. is gripped by the expanding sleeve 5 and flattened along the surface of the cone 2. The pores of the surface of the cone and the inner surface of the expansion sleeve 8 are plugged by the material of the sleeve 8. The resultant material a spacer cone and expansion sleeve, reducing the torque applied to the nut and increasing the spacer action. Depending on the material of the sleeve 8 and its dimensions, a layer of sliding material of varying thickness can be obtained between the expansion sleeve and the spacer cone. Particularly good results were achieved when testing using a sleeve 8 made of polyamide with a taper corresponding to the taper of the distance cone,,,. A soft metal, such as lead, can be used as the material for the sleeve 8. The proposed dowel increases the reliability of fastening during the subsequent expansion of the hole due to the increased thrust. Formula 1 and 3 of a bout 1. Spacing dowel containing a rod with a spacer cone at one end and fastener in the form of a screw at the other end, placed in the expansion sleeve with the possibility of retracting the spacer into it cone, characterized in that, in order to increase the reliability of fastening, it is provided with a sliding guide in the form of a sleeve of easily deformable material with antifriction properties, the expansion cone at the end facing the screw is made with an axial stop, the sleeve is mounted on the rod in contact with the stop thrust cone and the inner surface of the expansion sleeve and has an outer diameter greater than the diameter of the CCP;
