Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings, and particularly relates to a parallel groove clamp. Background Art

[0002] An electric power parallel groove clamp is a clamp used for fixing electric power lines and contacting the ground.

[0003] Refer to Figure 1 As shown: electric power line 01, clamp 02, power connection line 03. The electric power line 01 is subjected to skin-breaking treatment. One side of the clamp 02 is connected to the position of the skin-breaking treatment on the electric power line 01, and the other side of the clamp 02 is connected to the power connection line 03.

[0004] The above is the connection structure of an existing parallel groove clamp. The two sides of the clamp are clamped with the electric wires to form a fixed connection. Among them, on the side connected to the power connection line 03, when the power connection line 03 is pulled, the problem of loosening of the power connection line 03 may occur (on the side connected to the electric power line 01, due to the blockage of the outer skin of the line, the clamp is not easy to move, and even if a certain movement occurs, it will not break away). Content of the Utility Model

[0005] In view of the problems pointed out in the background art, the utility model provides a parallel groove clamp to solve the above technical problems.

[0006] The technical solution of the utility model is realized as follows:

[0007] A parallel groove clamp includes an upper clamping plate and a lower clamping plate. Upper clamping grooves are respectively arranged on both sides of the upper clamping plate, and lower clamping grooves are respectively arranged on both sides of the lower clamping plate.

[0008] An inward concave groove is arranged on one of the lower clamping grooves, and the groove is arranged along the length direction of the lower clamping groove;

[0009] A clamping block is arranged in the groove, and the clamping block is spaced from both ends of the groove;

[0010] Protrusions corresponding to the grooves on both sides of the clamping block are arranged on the upper clamping groove.

[0011] The utility model is further arranged such that the widths of both ends of the groove gradually become smaller.

[0012] The utility model is further arranged such that the clamping block protrudes from the clamping surface of the lower clamping groove.

[0013] The utility model is further arranged to include a connection hole penetrating through the upper clamping plate and the lower clamping plate.

[0014] The utility model is further arranged such that a friction structure for increasing friction is arranged on the clamping surface of the clamping block.

[0015] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0016] For the parallel groove clamp provided by the present utility model, when the clamp clamps and fixes the cable, the clamping block can assist in clamping and fixing. In this way, if the fixed cable needs to move axially, it will be restricted by the clamping block, and the movement of the clamping block will be restricted by both ends of the groove, thereby improving the clamping ability of the cable.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] The following is a description of the present utility model with reference to Figures 1-5 as follows:

[0025] Embodiment 1: A parallel groove clamp includes an upper clamping plate 1 and a lower clamping plate 2. Upper clamping grooves 3 are respectively provided on both sides of the upper clamping plate 1, and lower clamping grooves 4 are respectively provided on both sides of the lower clamping plate 2. It further includes a connection hole 7 penetrating through the upper clamping plate 1 and the lower clamping plate 2. A bolt is connected in the connection hole 7, and a nut is connected to the bolt. The upper clamping plate 1 and the lower clamping plate 2 are fixedly connected by the bolt and the nut. The above is the prior art, and the following is the improved technology of this application:

[0026] A concave groove 5 is provided on one of the lower clamping grooves 4. The groove 5 is strip-shaped and is arranged along the length direction of the lower clamping groove 4. A clamping block 7 is provided in the groove 5. The length of the clamping block 7 is less than the length of the groove 5. The clamping block 7 is spaced from both ends of the groove 5. The width of the clamping block 7 is equal to the width of the groove 5. The widths of both ends of the groove 5 gradually become smaller. Protrusions 6 corresponding to the grooves 5 on both sides of the clamping block 7 are provided on the upper clamping groove 3. With the above technical solution, when the upper clamping plate 1 and the lower clamping plate 2 cooperate to clamp and fix the cable, the protrusions 6 can squeeze the cable into the grooves 5 on both sides of the clamping block 7. In this way, the clamped cable is deformed and can be clamped more stably and firmly. At the same time, it is equivalent to a fixed connection between the clamping block 7 and the cable in the length direction.

[0027] The clamping block 7 protrudes from the clamping surface of the lower clamping groove 4, and a friction structure for increasing friction is provided on the clamping surface of the clamping block 7. The above structures are all for increasing the friction force between the clamping block 7 and the clamped cable.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
