AI Technical Summary
When existing tension clamps fix conductors with bolts, high-altitude swaying causes wear between the bolts and the conductor, increasing the gaps and affecting the fixing effect.
The clamp employs a sliding mechanism and a clamping mechanism within its body. By utilizing the cooperation of a fixing component, gears, and locking plates, the fixing component is pushed into close contact with the wire by a spring, and reverse movement is prevented by the meshing of gears and locking plates, thus achieving multi-point fixing.
It improves the stability of the wire fixation, prevents loosening caused by wear, and enhances the fixing effect.

[0021] The following is in conjunction with the appendix Figures 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0022] like Figures 1-4 As shown, this utility model discloses a tension clamp for fixing wires, comprising a clamp body 1, a wire groove 2 inside the clamp body 1, a through groove 3 on the side wall of the clamp body 1, a fixing member 4 installed in the through groove 3 via a sliding mechanism, the fixing member 4 being connected to a clamping mechanism, an internal groove 5 on the upper wall of the through groove 3, a gear rotatably mounted in the internal groove 5, a tooth groove 7 on the upper end face of the fixing member 4 engaging with the gear 6, and a locking piece 8 rotatably mounted on the inner side of the internal groove 5, the locking piece 8 unidirectionally limiting the gear 6, allowing the gear 6 to rotate only in one direction, indirectly... The fastener 4 is unidirectionally limited and fixed, so that the fastener 4 cannot be retracted and will not loosen. The locking piece 8 is fixedly connected to the side wall of the inner groove 5 through the first spring 9. The upper surface of the locking piece 8 is slidably fitted with the limiting piece 10 fixedly installed on the side wall of the inner groove 5. This device indirectly limits the fastener 4 through the gear 6 and the locking piece 8 and other components, ensuring that the fastener 4 stably clamps and fixes the wire. At the same time, the second spring 14 automatically pushes the fastener 4 to fit tightly with the wire, and ensures that when the fastener 4 wears, the fastener 4 can automatically move forward and fit with the wire.
[0023] Specifically, the sliding mechanism includes a connecting strip 11 that is horizontally fixedly installed on the lower end face of the fixing member 4. The connecting strip 11 is slidably connected to the through groove 3. The connecting strip 11 is set to realize the sliding connection between the fixing member 4 and the through groove 3, so that the fixing member 4 can move horizontally stably.
[0024] More specifically, the clamping mechanism includes a fixing rod 12 that is horizontally fixed to the outer wall of the clamp body 1. A fixing block is fixedly installed at the end of the fixing rod 12. A connecting piece 13 that is movably sleeved on the outer wall of the fixing rod 12 is fixedly installed on the upper surface of the fixing member 4. The connecting piece 13 is fixedly connected to the fixing block through a second spring 14. The second spring 14 is movably sleeved on the outer wall of the fixing rod. The second spring 14 indirectly pushes the fixing member 4 to move into the clamp body 1, ensuring close contact between the fixing member 4 and the wire, and ensuring stable fixation of the wire by the device.
[0025] Furthermore, multiple grooves 15 are continuously provided at the end of the fixing member 4. The grooves 15 increase the friction between the fixing member 4 and the wire, making the device more firmly fix the wire.
