Abstract

This utility model discloses a compression-type anti-corrosion cable clamp, including a base frame, an upper clamping arm, and a lower clamping arm. A pair of connecting rods are hinged to the base frame, and a pull rod is hinged to the end of the pair of connecting rods away from the base frame. Both the upper and lower clamping arms are hinged to the pair of connecting rods. When the pull rod moves outward, the pair of pull rods rotate synchronously, so that the upper and lower clamping arms on the pair of connecting rods move closer together. It also includes a protective structure disposed on the upper and lower clamping arms. The protective structure includes a first sleeve and a second sleeve. When the upper and lower clamping arms clamp and fix the cable, the first and second sleeves protect the clamped portion of the cable. By setting up the protective structure, this utility model ensures that when clamping the cable, the upper and lower shells of the first sleeve wrap around the cable from both above and below, allowing it to better fit the groove. The V-shaped structure of the groove can accommodate cables of different sizes, ensuring the stability of the clamping.

Description

Technical Field

[0001] This utility model relates to the field of cable clamp technology, and in particular to a compression-type anti-corrosion cable clamp. Background Technology

[0002] Cables are increasingly used in power transmission, and cable clamps, as key components for cable laying and fixing, have a crucial impact on the safe operation and service life of cables.

[0003] Existing cable clamps have several problems during long-term use: when the clamp holds and fixes the cable, the cable surface in contact with the clamp edge is easily damaged by the pressure, making the cable more susceptible to corrosion from external environmental factors such as moisture and chemicals. This corrosion affects the cable's insulation and conductivity, and may even lead to safety accidents. Therefore, a compression-type corrosion-resistant cable clamp is proposed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a compression-type anti-corrosion cable clamp.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a compression-type anti-corrosion cable clamp, comprising a base frame, an upper clamping arm, and a lower clamping arm. A pair of connecting rods are hinged to the base frame, and a pull rod is hinged to the end of the pair of connecting rods away from the base frame. The upper clamping arm and the lower clamping arm are both hinged to the pair of connecting rods. When the pull rod moves outward, the pair of pull rods rotate synchronously to bring the upper clamping arm and the lower clamping arm on the pair of connecting rods closer together. It also includes a protective structure disposed on the upper clamping arm and the lower clamping arm. The protective structure includes a first clamp and a second clamp. When the upper clamping arm and the lower clamping arm clamp and fix the cable, the first clamp and the second clamp protect the clamped portion of the cable.

[0006] As a further description of the above technical solution: the first clamping sleeve includes an upper shell fixedly connected to the upper clamping arm and a lower shell fixedly connected to the lower clamping arm. A compression protrusion is fixedly connected inside the upper shell, and a groove is opened inside the lower shell, with the cable located in the groove. A bracket is fixedly connected to one end of the base frame. A through hole is opened on the bracket, and a fixing plate is fixedly connected to the edge of the through hole. A fastening bolt is threadedly connected to the fixing plate. One end of the pull rod is inserted into the through hole, and the fastening bolt and the fixing hole opened on the pull rod are threadedly fixed. When the fastening bolt is fixed to the pull rod, the upper and lower clamping arms clamp the cable.

[0007] As a further description of the above technical solution: the upper shell and the lower shell are sized to match, the lower shell can slide inside the upper shell, the groove is a V-shaped structure to accommodate cables of different sizes, and the size of the extrusion protrusion is much smaller than the size of the groove.

[0008] As a further description of the above technical solution: the second jacket is in two sets, which are fixed to the two ends of the upper shell and the lower shell respectively, and each set includes two jackets. The two second jackets are fixedly connected to the upper shell and the lower shell respectively, and the two second jackets are arranged symmetrically up and down. The second jacket is made of EPDM rubber, and the two second jackets are combined to form a conical structure with the tip facing outward.

[0009] This utility model has the following beneficial effects:

[0010] 1. Compared with the prior art, this extrusion-type anti-corrosion cable clamp, by setting a protective structure, when clamping the cable, the upper shell and lower shell of the first clamp wrap the cable from the top and bottom directions respectively. The extrusion protrusion in the upper shell can squeeze the cable sheath during the clamping process, so that it fits the groove better. The V-shaped structure of the groove can adapt to cables of different sizes, ensuring the stability of clamping.

[0011] 2. Compared with the existing technology, this extrusion-type anti-corrosion cable clamp, by setting a second sleeve, which is made of EPDM rubber, has good elasticity, corrosion resistance and weather resistance. When the two second sleeves are combined into a conical structure with the tip facing outward, it can further enhance the protection of the clamped part of the cable, reduce the damage to the cable surface caused by clamping, effectively prevent external corrosive substances from entering the cable from the damaged part, thereby extending the service life of the cable and improving the reliability of power transmission.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5 As shown, the compression-type anti-corrosion cable clamp of this embodiment includes a base frame 1, an upper clamping arm 3, and a lower clamping arm 4. A pair of connecting rods 2 are hinged on the base frame 1. The ends of the pair of connecting rods 2 away from the base frame 1 are hinged to a pull rod 5. The upper clamping arm 3 and the lower clamping arm 4 are both hinged to the pair of connecting rods 2. When the pull rod 5 moves outward, the pair of pull rods 5 rotate synchronously so that the upper clamping arm 3 and the lower clamping arm 4 on the pair of connecting rods 2 move closer together. It also includes a protective structure, which is provided on the upper clamping arm 3 and the lower clamping arm 4. The protective structure includes a first clamping sleeve 11 and a second clamping sleeve 12. When the upper clamping arm 3 and the lower clamping arm 4 clamp and fix the cable 13, the first clamping sleeve 11 and the second clamping sleeve 12 protect the clamped part of the cable 13.

[0021] The first clamping sleeve 11 includes an upper shell 14 fixedly connected to the upper clamping arm 3 and a lower shell 16 fixedly connected to the lower clamping arm 4. An extrusion protrusion 15 is fixedly connected inside the upper shell 14, and a groove 17 is opened inside the lower shell 16, with the cable 13 located in the groove 17. A bracket 7 is fixedly connected to one end of the base frame 1. A through hole 8 is opened on the bracket 7, and a fixing plate 10 is fixedly connected to the opening of the through hole 8. A fastening bolt is threaded onto the fixing plate 10. One end of the pull rod 5 is inserted into the through hole 8, and the fastening bolt is threadedly fixed to the fixing hole 9 opened on the pull rod 5. When the fastening bolt is fixed to the pull rod 5, the upper clamping arm 3 and the lower clamping arm 4 clamp the cable 13.

[0022] In actual use, the cable 13 is first placed in the groove 17 of the lower shell 16, and then the pull rod 5 is moved outward to make the pair of connecting rods 2 rotate synchronously, driving the upper clamping arm 3 and the lower clamping arm 4 to move towards each other until the upper shell 14 and the lower shell 16 clamp the cable 13. At this time, the extrusion protrusion 15 of the first clamping sleeve 11 extrudes the cable 13, making it firmly embedded in the groove 17. At the same time, the second clamping sleeve 12 tightly wraps around the outer periphery of the cable 13, forming multiple layers of protection. Finally, the pull rod 5 is locked by the fastening bolt on the fixing plate 10 and the fixing hole 9 on the pull rod 5, ensuring that the upper clamping arm 3 and the lower clamping arm 4 maintain a stable clamping force on the cable 13, thus completing the fixed installation of the cable.

[0023] The upper shell 14 and the lower shell 16 are sized to match, for example, the inner diameter of the upper shell 14 is 50mm and the outer diameter of the lower shell 16 is 48mm, so that the lower shell 16 can slide inside the upper shell 14. The groove 17 is a V-shaped structure with an opening greater than 40mm to accommodate cables 13 of different sizes, and the size of the extrusion protrusion 15 is 10mm, which is much smaller than the size of the groove 17. When clamping the cable, the extrusion protrusion 15 can extrude and fix cables of different diameters, making them more securely embedded in the groove 17.

[0024] The second sleeve 12 consists of two sets, fixed to both ends of the upper shell 14 and the lower shell 16 respectively, with each set comprising two sleeves. The two second sleeves 12 are fixedly connected to the upper shell 14 and the lower shell 16 respectively, and are symmetrically arranged vertically. The second sleeves 12 are made of EPDM rubber, and when combined, they form a conical structure with the pointed end facing outwards. This material possesses weather resistance, ozone resistance, heat resistance, and chemical corrosion resistance, enabling it to maintain good performance over a long period under various harsh environmental conditions. When assembled, they form a conical structure with the tip pointing outwards. This structure not only further enhances the protection of the cable, preventing direct impact and friction from external objects, but also effectively blocks some moisture, dust, and other impurities from entering the contact area between the cable and the clamp, thereby reducing the generation and penetration of corrosive water and lowering the risk of cable corrosion. In addition, since the second clamp 12 clamps and fixes both ends of the cable, and the second clamp 12 is elastic, its edges will not cause damage to the cable when the second clamp 12 squeezes the cable, avoiding the problem of traditional clamps easily damaging and cutting the cable.

[0025] Working principle: When it is necessary to clamp the cable, the operator moves the pull rod 5 outward. Since the pull rod 5 is hinged to the end of the connecting rod 2 away from the base frame 1, and the other end of the connecting rod 2 is hinged to the base frame 1, the movement of the pull rod 5 will drive the connecting rod 2 to rotate synchronously around the hinge point on the base frame 1. As the connecting rod 2 rotates, the upper clamping arm 3 and the lower clamping arm 4, which are hinged to it, move towards each other under the drive of the connecting rod 2, gradually approaching and finally clamping the cable in the middle.

[0026] During the clamping process, the upper shell 14 on the upper clamping arm 3 and the lower shell 16 on the lower clamping arm 4 wrap the cable from the upper and lower directions respectively. The cable is stably placed in the V-shaped groove 17 of the lower shell 16. The extrusion protrusion 15 in the upper shell 14 extrudes the cable sheath under the action of clamping force, making the cable fit more tightly with the groove 17, thereby ensuring the stability of the clamping. At the same time, the second sleeve 12 fits tightly against the outer periphery of the cable as the upper shell 14 and the lower shell 16 close, forming an effective protective barrier.

[0027] When adjusting the clamping force, the operator can loosen the fastener on the fixing plate 10, move the pull rod 5 to the appropriate position, and then tighten the fastener again to align and fix the fixing hole 9 on the pull rod 5 with the threaded hole on the fixing plate 10, thereby achieving precise adjustment of the clamping force to meet the needs of different cable specifications and usage scenarios.

[0028] During the long-term use of the cable, the protective structure of this clamp can effectively prevent external corrosive substances from eroding the cable and extend its service life. The EPDM rubber material of the second jacket 12 has good elasticity and corrosion resistance, and can resist the erosion of various harsh environments, such as acid rain, salt spray, and ultraviolet rays. At the same time, its tapered structure with the tip pointing outward can block some moisture, dust and other impurities from entering the contact area between the cable and the clamp, reducing the generation and penetration of corrosive water.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
