Description

Technical Field

[0001] The utility model relates to the field of devices for adjusting the tension of conductors, and more specifically to a two-core tension-resistant wire clamp. Background Art

[0002] The insulated wires are fixed to the clamps and walls by hanging wire clamps. However, the distance between adjacent hanging wire clamps is far, and the insulated wires become heavier as their length increases, causing them to sag downward and form an arc. In this case, the wires will sway greatly, causing great wear on the joints, shortening the service life of the wires and reducing safety. Therefore, tension clamps are required to tighten the wires every few hanging wire clamps. Existing tension clamps are only for single wires or four wires, and there are no tension clamps for two-core wires. If a tension clamp for a single wire is used, the operation needs to be done twice, which is cumbersome. If a tension clamp for a four-core wire is used, two through holes are left vacant, causing unbalanced force on the tension clamp and low stability. Utility Model Content

[0021] Through the above technical solution, the pull rod 1 is connected to the clamp, the electric pole or the wall.

[0022] Before installation, the fixing bolts 5 and the fixing nuts 51 connect the insulating cover plate 4, the clamping plate 3 and the insulating seat 22. The insulating cover plate 4 and the clamping plate 3 are movable, and the insulating seat 22 is movable on the pull rod 1. All parts are connected to each other, and there is no need to take them separately, which is convenient for installation and avoids omission.

[0023] During installation, the broken double-core wires are placed in the first fixing groove 221 and the second fixing groove 41 on both sides respectively, and then the fixing nut 51 is tightened so that the two wires are fixed in the first fixing groove 221 and the second fixing groove 41, and then the tensioning nut 11 is rotated. The tensioning nut 11 rotates and moves, thereby driving the tension seat 2 to move, and then tensioning the wires.

[0025] The connecting groove 212 is located in the pull rod 1, and its height part overlaps with the pull rod 1. The insulating seat 22 is arranged in the connecting groove 212, and its height part overlaps with the pull rod 1. After fixing, the pull rod 1 and the wire are balanced in force, and the stability is high.

[0026] Specifically, a gasket is provided between the tensioning nut 11 and the tension-resistant seat 2 to prevent the tensioning nut 11 from loosening.

[0027] Specifically, a gasket is provided between the fixing nut 51 and the clamping plate 3 to prevent the fixing nut 51 from loosening.

[0028] Specifically, both ends of the insulating seat 22 have positioning edges to facilitate positioning of the insulating seat 22 and the connecting portion 21 .

[0029] As an improved specific implementation, the connecting portion 21 is formed in one piece, the movable hole 211 is formed by bending, and the connecting groove 212 is formed by stamping.

[0030] Through the above technical solution, the connecting portion 21 is integrally formed, the movable hole 211 is formed by bending, and the connecting groove 212 is formed by stamping, so the structure has high strength.

[0031] As an improved specific implementation, the insulating seat 22 is glued and fixed to the connecting groove 212 .

[0032] Through the above technical solution, the insulating seat 22 and the connecting groove 212 are glued and fixed, which is convenient for installing the wire.

[0033] As an improved specific implementation, a groove 43 is provided on the insulating cover plate 4 , and the groove 43 is located between the second fixing grooves 41 , and the opening of the groove 43 is oriented in the same direction as the opening of the second fixing grooves 41 .

[0034] Through the above technical solution, the groove 43 is arranged on the side of the insulating cover plate 4 facing the insulating seat 22, which reduces the weight and quality of the insulating cover plate 4, makes assembly easier, reduces material usage, and reduces costs.

[0035] The opening of the groove 43 and the opening of the second fixing groove 41 are oriented in the same direction, and the contact surface between the insulating cover plate 4 and the clamping plate 3 is flat, and the stability is high after clamping, thereby preventing deformation and loosening.

[0036] As an improved specific implementation, the insulating cover plate 4 is provided with a weight-reducing groove 44 on the side facing the clamping plate 3 , and the position of the weight-reducing groove 44 corresponds to the position of the second fixing groove 41 .

[0037] Through the above technical solution, the insulating cover plate 4 at the position of the second fixing groove 41 is thicker, and the weight-reducing groove 44 is provided to reduce the mass of the insulating cover plate 4 without affecting the structural strength, making assembly easier, reducing material usage and reducing costs.

[0038] As an improved specific implementation, both sides of the insulating seat 22 are provided with outwardly extending retaining edges 223 .

[0039] Through the above technical solution, the blocking edge 223 extends outward, increasing the distance between the wire and the connecting portion 21, further avoiding leakage and improving safety.

[0040] As an improved specific implementation, a first protrusion 2211 is provided in the first fixing groove 221 , and a second protrusion 411 is provided in the second fixing groove 41 .

[0041] Through the above technical solution, the first protrusion 2211 and the second protrusion 411 contact the surface of the wire, thereby increasing the friction coefficient and preventing the wire from slipping between the first fixing groove 221 and the second fixing groove 41 during the tensioning process, thereby facilitating use.

[0042] As an improved specific implementation, the first fixing groove 221 and the second fixing groove 41 are arranged obliquely.

[0043] Through the above technical solution, the first fixed groove 221 and the second fixed groove 41 are inclined. As the tension seat 2 moves away from the opening position of the pull rod 1, the angle of the wire suspension changes, and the first tension seat 2 and the second tension seat 2 are clamped tighter with the wire to avoid looseness, thereby improving stability during use.

[0044] As an improved specific implementation, the bending portion of the pull rod 1 is provided with a limiting portion 12, and the limiting portion 12 is made of insulating material.

[0045] Through the above technical solution, the limiting portion 12 is arranged at the bent position of the pull rod 1, and is used to interfere with the connecting portion 21, so that the connecting portion 21 can stably slide on the straight part of the pull rod 1, avoiding the connecting portion 21 from getting stuck, thereby improving the stability during use; the limiting portion 12 is connected to the clamp, wall, etc., and is made of insulating material to avoid leakage, thereby further improving safety.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
