Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a suspension wire clamp with improved stability. Background Art

[0002] Suspension clamps are commonly used in fixed products. The U-bolt style (commonly called boat-shaped clamps) is now retained. It consists of a bracket U-bolt, a clamp hull made of malleable cast iron, and a pressure plate. The other type is a pre-twisted suspension clamp. The suspension clamp is used to fix the conductor to the insulator string of a straight pole tower, or to suspend the lightning conductor on a straight pole tower. It can also be used to support the transposed conductor on the transposed pole tower and fix the jumper of the tension-resistant corner pole tower.

[0003] Since the cables are exposed to the outdoors for a long time, the insulation on the cable surface will age and corrode, reducing the contact area and friction between the cables and the suspension clamps, causing the cables to loosen, displace, and slide on the suspension clamps, thereby affecting the stability of power transmission. Therefore, the applicant has made a useful design and found a solution to the above-mentioned problem. The technical solution to be introduced below was produced in this context. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned traditional suspension wire clamp design and provide a product that improves the stability of the wire clamp.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] A suspension wire clamp with improved stability includes a bearing member and a pressure plate, the bearing member is provided with a wire clamping groove, the wire clamping groove is provided with a pressure strip, U-shaped fixing rings are provided on both sides of the bearing member and abut the pressure strip, the U-shaped fixing ring passes through the pressure plate, the wire clamping groove is provided with a liftable clamping block, the clamping block is provided with several protrusions, the pressure plate is provided with a spring and abuts the clamping block, the U-shaped fixing ring is threadedly connected with a nut and abuts the pressure plate.

[0007] Preferably, the wire clamping groove is provided with a sliding groove for accommodating the clamping block, and limiting through holes are provided on both sides of the sliding groove, and a baffle is provided at the entrance of the limiting through hole.

[0008] Preferably, limiting blocks are provided on both sides of the clamping block and are slidably arranged in the limiting through hole, and the clamping block is provided with at least two blind holes.

[0009] Preferably, the pressure plate is provided with a cylinder corresponding to the blind hole, and the spring is arranged on the outer wall of the cylinder and abuts against the blind hole.

[0011] Beneficial effects:

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model applies elastic force released by the spring to the clamping block, so that a force is formed between the clamping block and the pressure plate to clamp the cable. At the same time, as the nut is gradually tightened, the U-shaped fixing ring presses the pressure strip against the wire clamping groove, further improving the force of clamping the cable. In addition, a number of protrusions increase the friction between the cable, the wire clamping block and the pressure strip, preventing loosening, displacement and sliding, so that the product has the advantage of improving the stability of wire clamping.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0022] Reference example Figures 1 to 3 The U-shaped fixing ring 4 is provided with a clamping groove 11, and the clamping groove 11 is provided with a pressure strip 3. Both sides of the bearing member 1 are provided with a U-shaped fixing ring 4, which abuts the pressure strip 3. The U-shaped fixing ring 4 passes through the pressure plate 2, and the clamping groove 11 is provided with a liftable clamping block 5, and the clamping block 5 is provided with several protrusions 51. The pressure plate 2 is provided with a spring 6 and abuts the clamping block 5. The U-shaped fixing ring 4 is threadedly connected with a nut 41 and abuts the pressure plate 2. The elastic force released by the spring 6 is applied to the clamping block 5, so that a force is formed between the clamping block 5 and the pressure plate to clamp the cable. At the same time, as the nut 41 is gradually tightened, the U-shaped fixing ring 4 presses the pressure strip 3 to the clamping groove 11, further improving the force of clamping the cable, and the several protrusions 51 increase the friction between the cable, the clamping block and the pressure strip 3 to prevent loosening, displacement and sliding.

[0023] It is worth mentioning that the wire clamping groove 11 is provided with a chute 12 for accommodating the clamping block 5. Limiting holes 13 are provided on both sides of the chute 12. A baffle 14 is provided at the entrance of the limiting hole 13. The chute 12 provides a guide for the clamping block 5. The limiting hole 13 limits the rising distance of the clamping block 5, and the baffle 14 limits the descending distance of the clamping block 5.

[0024] It is worth mentioning that the clamping block 5 is provided with a limit block 52 on both sides and is slidably set in the limit through hole 13. The clamping block 5 is provided with at least two blind holes 53. The limit blocks 52 are used in conjunction with the limit through hole 13 and the baffle 14. The blind holes 53 concentrate the elastic force of the spring 6 and increase the accommodation space of the spring 6.

[0025] It is worth mentioning that the pressure plate 2 is provided with a cylinder 21 corresponding to the blind hole 53, and the spring 6 is arranged on the outer wall of the cylinder 21 and abuts against the blind hole 53. The cylinder 21 prevents the spring 6 from escaping;

[0026] It is worth mentioning that the clamping block 5 is provided with an arc-shaped interference portion 54 , and the protrusion 51 is provided on the surface of the interference portion 54 , so that the interference portion 54 increases the contact area with the cable.
