The invention relates to the spacer dowel plastic with located at one end of the belt, which is fixed to the rod spacer dowels and clamp with lock.

From the patent of the Russian Federation No. 2083885 “Spacer dowel plastic” known spacer dowel at the rear end, at the output of the channel has a cylindrical section whose diameter matches the outside diameter of the fixing screw, and is connected with it tapering section, the amount of which in the plane of the slot along the length of the narrowing corresponds to the diameter of the cylindrical section and in the plane perpendicular to the slits decreases toward the front end of the body. Cross-section tapering section of the channel has the shape of a rhombus with one diagonal of which coincides with the plane of the slot.

Closest to the claimed invention is a screw anchors for dry wall and blind holes for U.S. patent US No. 057911845 containing a monolithic body made of two halves with a flat surface and two ends, which are made semicircular flat flanges. Midway between the ends is hinged portion which connects the housing halves. The device is folded around the hinge portion of the contact flanges, which form when the round head. The semi-cylinders form a cylindrical dowel, is being provided in the hole, and grooves form a threaded cylindrical hole of the threaded fastening element, when screwing in which the hinged section is broken, and nerushimoye sections are moved apart, fixing device inside the pylon.

The above-described devices have inherent disadvantages, namely, that when carrying out, for example, electrical work required in addition to the dowels to apply a separate clamp and fastening element, clipping them onto the dowel.

The basis of the invention is tasked to improve the dowel so that he, combining three parts, allowed to achieve greater productivity when carrying out, for example, electrical work.

The problem is solved as follows. Dowel electrical plastic consists of two semi-cylinders, combined rectangular belt with a clamp consisting of two ends, and at the long end made the notch, and the short has a lock, and with a cylindrical rod.

The invention meets the criterion of “novelty”, as from publicly available sources is not known technical solutions, characterized by the above described set of essential features.

The invention meets the criterion of “inventive step”as a standard solution for the connection of the three parts (plugs, Goatika rod) in one achieves greater productivity, for example, electrical work.

The proposed device is explained using the drawings.

Figure 1 shows the dowel electrical, prepare for installation; figure 2 is a view of the dowel from above; figure 3 is a view of the dowel directly.

Dowel electrical plastic consists of two semi-cylinders 1 with the outer surfaces of, for the most part, which made gear cutting 2. The remaining lower portion is made smooth. The inner surface of the semi-cylinders have a semiconical shape and provided with a longitudinal convex grooves 3, the length corresponding to the length of the serrated cutting. On the front end of the dowel has a lock, consisting of a groove 4, performed on one half, and the tongue 5, performed on the other half. The rear ends of the semi-cylinders combined rectangular belt 6 with the clamp having two ends - short and long, with the short end has a lock with a fastening tongue 7, and the long end of 8 completed with a notch and has a sharp end. Also on the belt fixed cylindrical rod 9 so that when the connection parts of the coupling, its lower part is inside the dowels, and the large was outside.

The device operates as follows. Before the introduction of the dowel into the hole two half 1 are connected together and are fastened to the castle with the help of the tongue 5 and groove is 4, forming the dowel. Then the dowel is inserted into the prepared hole and hammer cylindrical rod 9 is hammered into the internal cavity of the dowel. As the internal cavity of the anchor has a conical shape, the rod 9, penetrating deep into the radially bursting with its rigidly locking the anchor in the wall. Longitudinal grooves 3 are guides for the rod 9. Gear cutting 2, made on the outer surface of the dowel, is oriented so that prevents pulling out the plugs from the wall. When carrying out electrical work clamp 8 surrounds the electric wire and being threaded into the lock 7, there is fixed a mounting tongue.

1. Plug wiring made of plastic, consisting of two semi-cylinders with the outer surfaces of, for the most part, which made gear cutting, and semiconical inner surfaces provided with a longitudinal convex grooves, characterized in that it also includes rectangular flanges are made on the rear ends of the semi-cylinders, clamp with two ends - short and long, with the short end has a lock with mounting tab, and the long end is made with a notch, and a cylindrical rod, having the ability to penetrate into the inner cavity dowels, radially respira it, while the rear ends of the semi-cylinders of the United mentioned PR is mogannam belt with buckle and a cylindrical rod.

2. Dowel according to claim 1, characterized in that the front end has a lock, consisting of a groove made in one half, and reed made by the other half.
