Description

Technical Field

[0001] This utility model belongs to the field of wire clamp technology, specifically relating to a securely installed tension wire clamp. Background Technology

[0002] With the continuous growth of electricity demand and the ongoing expansion of the power grid, higher requirements have been placed on the stability and security of power transmission. Wire clamps are metal accessories that can be fixed to conductors. Most of them need to withstand large tensile forces during operation. They are mainly used to fix or connect conductors. As an important connection and fixing element in power lines, wire clamps play an important role in various fields such as public buildings, residential buildings, factories, mining, power, highways, handicrafts manufacturing, automobiles, metallurgy, petrochemicals, and aerospace.

[0003] Currently, there are many types of wire clamps on the market, including equipment clamps, fusion clamps, wire holding clamps, terminal clamps, piercing grounding clamps, tightening clamps, and insulation piercing clamps. Among them, wire holding clamps and tightening clamps are mainly used for holding or fixing wires, facilitating operation and construction, or for tightening and fixing wires to ensure the tension and stability of the wires. However, traditional wire clamp structures usually use a two-piece clamping structure to hold the cable. During cable construction or operation, the cable is easily slipped off the clamp due to excessive cable tension, affecting the normal construction or operation of the cable. Therefore, this application proposes a securely installed tension clamp. Utility Model Content

[0025] 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.

[0026] This embodiment provides a securely installed tension clamp, the structural diagram of which is shown below. Figures 1-4As shown, the device includes a base plate 1. Both ends of the top of the base plate 1 are provided with bosses 2. A pair of clamping blocks 3 are movably disposed between the pair of bosses 2. The pair of clamping blocks 3 and the bosses 2 are arranged in parallel. An adjusting component is provided between the pair of clamping blocks 3 to drive the pair of clamping blocks 3 away from or towards each other. The adjusting component includes a sleeve 8 and a lead screw 9 respectively mounted on the opposite side of the pair of clamping blocks 3. The sleeve 8 and the lead screw 9 are distributed perpendicular to the clamping blocks 3 and are threadedly connected to each other. The lead screw 9 is rotatably connected to the clamping blocks 3, and the sleeve 8 is fixedly connected to the clamping blocks 3. A recess 11 is provided on the outer wall of the sleeve 8 facing the lead screw 9. A hexagonal end block 10 is fixedly fitted on the end of the lead screw 9 away from the sleeve 8. A cable is passed between the clamping blocks 3 and the bosses 2, and then the hexagonal end block 10 is turned to make the lead screw 9 and the sleeve 8 rotate relative to each other, pushing the pair of clamping blocks 3 away from each other. This allows the cable to be clamped and positioned between the bosses 2 and the clamping blocks 3. The structure is simple, the operation is convenient, and it is suitable for cables of different thicknesses.

[0027] Furthermore, in this embodiment, a second arcuate groove 15 is formed along the length direction on the facing sides of a pair of bosses 2, and the clamping block 3 can be horizontally embedded in the second arcuate groove 15. A first arcuate groove 7 is formed on the far sides of the pair of clamping blocks 3. Through the first arcuate groove 7 and the second arcuate groove 15 respectively formed on the clamping block 3 and the bosses 2, and the clamping block 3 can be embedded in the second arcuate groove 15, the cable can be clamped and held, which can prevent the cable from slipping out, and has good resistance to cable tension, thus improving the reliability of cable clamping and fixing. A first rubber pad 12 is adhered to the inner wall of the first arcuate groove 7, and a second rubber pad 16 is adhered to the inner wall of the second arcuate groove 15, which can reduce wear on the cable.

[0028] In this embodiment, both ends of the substrate 1 are provided with fixing lugs 5, and the fixing lugs 5 are provided with mounting holes 6 for mounting and fixing the substrate 1.

[0029] Furthermore, in this embodiment, a pressure strip 4 for upper limit positioning of clamping block 3 is provided between the tops of a pair of bosses 2. One end of the pressure strip 4 is hinged to the top of one of the bosses 2, and the other end of the pressure strip 4 is provided with an assembly slot 20 that penetrates the end face of the pressure strip 4. A stud that can be embedded in the assembly slot 20 is vertically fixed on the boss 2. A hexagonal nut 18 is threaded on the stud 17. The outer diameter of the hexagonal nut 18 is larger than the width of the assembly slot 20. A protrusion 19 that can be embedded between a pair of bosses 2 is provided on the lower surface of the pressure strip 4. The bottom of the protrusion 19 slides against the upper surface of clamping block 3. After the bosses 2 and clamping block 3 clamp and fix the cable, the pressure strip 4 is horizontally abutted against the top of a pair of bosses 2. The hexagonal nut 18 is fitted on the stud 17 and screwed to abut against the pressure strip 4, which can fix the pressure strip 4. The protrusion 19 at the bottom of the pressure strip 4 can then upper limit the clamping block 3. A guide groove 14 is provided on the substrate 1. The guide groove 14 is distributed perpendicular to the clamping block 3. A guide block 13 is provided at the bottom of the clamping block 3 and slides into the guide groove 14. By using the guide groove 14 and the guide block 13 at the bottom of the clamping block 3 to cooperate, the lateral movement of the clamping block 3 can be restricted, which can further prevent the cable from loosening and slipping.

[0030] Working principle: In use, the cable is passed between the clamping block 3 and the boss 2. Then, the hexagonal end block 10 is turned to make the screw 9 and the sleeve 8 rotate relative to each other, pushing the pair of clamping blocks 3 away from each other until the pair of clamping blocks 3 are respectively embedded in the second arc groove 15 on the pair of bosses 2, clamping and positioning the cable. Then, the pressure strip 4 is rotated to abut against the top of the pair of bosses 2. The hexagonal nut 18 is put on the stud 17 and screwed to abut against the pressure strip 4 to fix the pressure strip 4. At this time, the protrusion 19 at the bottom of the pressure strip 4 limits the clamping block 3. The guide groove 14 and the guide block 13 at the bottom of the clamping block 3 cooperate to restrict the lateral movement of the clamping block 3. Finally, the base plate 1 is fixed by using the fixing ear block 5 and the mounting hole 6, which can realize the clamping and fixing of the cable, so as to facilitate the operation and construction of the cable, or ensure the stable operation of the cable.
