Description

Technical Field

[0001] This utility model relates to the field of tension clamp technology, specifically a tension-resistant power line clamp. Background Technology

[0002] Tension clamps are hardware used to fix conductors to withstand conductor tension and hang conductors on tension strings or towers. Tension clamps are used for cornering, splicing, and termination connections. The clamps are easy and quick to install, reducing construction costs. Tension clamps are used to fix conductors or lightning protection wires to tension insulator strings on non-straight towers, acting as anchors, and are also used to fix guy wires on guyed towers.

[0003] In the prior art, such as the tension clamp proposed in patent application number "CN202222591174.2", the two ends of the inner curved buckle plate of the secondary cable on the inner buckle side of the trapezoidal cable are provided with secondary cable reinforcing cylinders. The secondary cable is inserted into the secondary cable reinforcing cylinder, and a secondary cable compression screw is embedded on one side of the secondary cable reinforcing cylinder, which can compress and fix the secondary cable to the secondary cable reinforcing cylinder, thereby further reinforcing the secondary cable, preventing the secondary cable from falling off, and making it more practical.

[0004] However, in the aforementioned patent application, when using tension clamps to connect conductors, the conductors need to be inserted into the tension clamp's component for holding the conductors. However, if the component for holding the conductors is long, it is difficult to observe the condition of the inserted part of the conductor, which can easily lead to bending or twisting of the conductors, resulting in damage to the stability of the subsequent connection, and in severe cases, damage to the conductors.

Two connecting shells are fixedly connected to one end of the main body. Connecting support plates are inserted into the two connecting shells. Two support plates are fixedly connected to the bottom surface of the fixing plate. A connecting shaft is rotatably connected between the outer walls of the two support plates. The connecting shaft is fixedly connected to the two connecting support plates. Circular plates are fixedly connected to both ends of the connecting shaft. An adjustment mechanism is provided between one of the circular plates and the outer wall of the support plate.

[0008] The clamping mechanism includes two semi-circular outer clamping plates and a slide bar. The two semi-circular outer clamping plates are movably installed inside the circular long groove, and the slide bar is inserted into the inner wall of the circular long groove near the bottom.

An insulating sleeve is fixedly connected to one end of each of the two semi-circular inner clamps. A magnetic strip is fixedly installed inside each of the two insulating sleeves, and the two magnetic strips cooperate with each other.

[0010] Preferably, a U-shaped pull plate is fixedly connected to one end of the slide bar, and connecting plates are fixedly connected to both ends of the two semi-circular outer clamps. Screws are inserted into the outer walls of the two connecting plates near both ends, and nuts are fitted onto the outer sides of the two screws near both ends.

[0011] Preferably, the adjustment mechanism includes two L-shaped blocks, both of which are fixedly installed on the outer wall of one of the support plates. The inner walls of both L-shaped blocks are fixedly connected with telescopic connecting rods, and the outer sides of both telescopic connecting rods are fitted with return springs.

[0012] Preferably, a vertical plate is fixedly connected between one end of the two telescopic connecting rods, and two insert rods are fixedly connected to the outer wall of the vertical plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model involves removing two semi-circular inner clamps from the circular long groove, opening the two semi-circular inner clamps, and placing one end of the wire to be connected between the two open semi-circular inner clamps. The state of the wire end can be easily observed. Then, the two semi-circular inner clamps are rotated back to their initial positions, causing the two magnetic strips to attract each other and fix the position between the two semi-circular inner clamps. This clamps and fixes one end of the wire to be connected between the two semi-circular inner clamps. Then, the slider and the two semi-circular inner clamps are reinserted into the circular long groove to complete the operation of placing the wire in the clamp. Through the above operation, the wire to be connected can be conveniently placed into the clamp without manual insertion, avoiding twisting and bending of the wire and ensuring the normal placement of the wire.

[0017] 2. This utility model allows the main body to be rotated to a vertical position by releasing the position of the connecting shaft and then rotating the circular plate by 90°, thereby rotating the connecting shaft by 90°. This enables the wire to be connected vertically. Similarly, the main body can be rotated to a horizontal position for horizontal connection of the wire. The circular plate can be easily fixed by the spring force of the return spring in conjunction with the insertion rod, through hole and slot, thus easily fixing the position of the main body. Through the above operations, it is easy to adjust the main body to a horizontal or vertical position to adapt to the connection requirements of different wires and effectively improve adaptability.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A tension-resistant power line clamp, such as Figures 1-5 As shown, the device includes a main body 1 and a fixing plate 17. Several circular long slots 2 are opened through the outer wall of the main body 1. Each of the circular long slots 2 is equipped with a clamping mechanism. Two connecting shells 11 are fixedly connected to one end of the main body 1. Connecting support plates 12 are inserted into the two connecting shells 11. Two support plates 16 are fixedly connected to the bottom surface of the fixing plate 17. A connecting shaft 13 is rotatably connected between the outer walls of the two support plates 16. The connecting shaft 13 is fixedly connected to the two connecting support plates 12. Circular plates 14 are fixedly connected to both ends of the connecting shaft 13. An adjustment mechanism is provided between one of the circular plates 14 and the outer wall of the support plate 16. The clamping mechanism includes two semi-circular outer clamping plates 8 and a slide bar 6. The two semi-circular outer clamping plates 8 are movably installed inside the circular long slots 2. The slide bar 6 is inserted into the inner wall of the circular long slot 2 and is close to the bottom.

[0028] Several supporting springs are installed between the outer walls of the two semi-circular outer clamping plates 8 and the inner wall of the circular long groove 2. The two outer walls of the slide bar 6 are rotatably connected to the semi-circular inner clamping plates 3 via shafts. Insulating sleeves 4 are fixedly connected to one end of the two semi-circular inner clamping plates 3. Magnetic strips 5 are fixedly installed inside the two insulating sleeves 4, and the two magnetic strips 5 cooperate with each other. A U-shaped pull plate 7 is fixedly connected to one end of the slide bar 6. Connecting plates 9 are fixedly connected to both ends of the two semi-circular outer clamping plates 8. Screws 10 are inserted into the outer walls of the two connecting plates 9 near both ends. Nuts are fitted on the outer sides of the two screws 10 near both ends.

[0029] In use, the slider 6 is pulled outward from the circular groove 2 by the U-shaped pull plate 7, which drives the two semi-circular inner clamps 3 to move outward from the circular groove 2 until the two semi-circular inner clamps 3 are completely removed from the circular groove 2. At this time, the two semi-circular inner clamps 3 are rotated around the connection point with the slider 6 as the central axis, so that the two semi-circular inner clamps 3 are opened. Then, one end of the wire to be connected is placed between the two open semi-circular inner clamps 3. Then, the two semi-circular inner clamps 3 are rotated back to their initial position, so that the two magnetic strips 5 are attracted together, fixing the position between the two semi-circular inner clamps 3. Thus, one end of the wire to be connected can be clamped and fixed between the two semi-circular inner clamps 3. Then, the slider 6 and the two semi-circular inner clamps 3 are reinserted into the circular groove 2 to complete the operation of placing the wire in the clamp. Through the above operation, the wire to be connected can be conveniently placed into the clamp without manual insertion, ensuring the normal placement of the wire.

[0030] Reinsert the slider 6 and the two semi-circular inner clamps 3 into the circular long groove 2. After placing the wire into the clamp, pass the screw 10 through the two connecting plates 9. Then, rotate the two nuts to the outside of the screw 10 near both ends. Continue to rotate along the screw 10 to press the two connecting plates 9 together, causing the two connecting plates 9 to move closer to each other. This causes the two semi-circular outer clamps 8 to move closer to each other, clamping and fixing the two semi-circular inner clamps 3. This fixes one end of the wire inside the circular long groove 2, completing the connection and fixing of the wire.

[0031] The adjustment mechanism includes two L-shaped blocks 18, both of which are fixedly installed on the outer wall of one of the support plates 16. Telescopic connecting rods 19 are fixedly connected to the inner walls of both L-shaped blocks 18. Return springs are sleeved on the outside of each telescopic connecting rod 19. A vertical plate 15 is fixedly connected between one end of each telescopic connecting rod 19. Two insert rods 20 are fixedly connected to the outer wall of the vertical plate 15. Two slots 21 are opened on the outer wall of the support plate 16, and the slots 21 fit into the insert rods 20. Several through holes are opened through the outer wall of the circular plate 14. One end of each insert rod 20 passes through a through hole and is movably installed inside the slot 21. Under the action of the return spring, the telescopic connecting rod 19 shortens, causing the insert rod 20 to pass through the corresponding through hole and insert into the slot 21, thus fixing the circular plate 14.

[0032] The upper surface of the fixing plate 17 has a through-hole for mounting. A fixing nail 22 is inserted into the upper surface of the connecting shell 11 near one end. The upper surface of the connecting support plate 12, located inside the connecting shell 11, has several fixing holes that fit with the fixing nails 22. The fixing plate 17 can be connected to the connector on the utility pole through the mounting holes to complete the connection between the clamp and the utility pole, thereby completing the operation of connecting the wire to the utility pole. By moving the connecting support plate 12 along the inside of the connecting shell 11, the distance between the main body 1 and the fixing plate 17 can be adjusted to accommodate different installation distances between the main body 1 and the utility pole. After adjustment, the fixing nails 22 can be inserted through the connecting shell 11 into the corresponding fixing holes to fix the position between the connecting shell 11 and the connecting support plate 12.

[0033] Specifically, moving the vertical plate 15 away from the circular plate 14 causes the two insert rods 20 to move out of the slots 21 and through holes. One end of the telescopic connecting rod 19 moves with the vertical plate 15, extending as a whole. The return spring is stretched, releasing the fixation on the circular plate 14 and thus releasing the position of the connecting shaft 13. At this time, rotating the circular plate 14 by 90° causes the connecting shaft 13 to rotate by 90°, causing the main body 1, connected by the two connecting support plates 12 and the connecting shell 11, to rotate to a vertical position, allowing the wire to be hung vertically. Similarly, the main body 1 can be rotated to a horizontal position for horizontal connection of the wire. After adjustment, releasing the pull on the vertical plate 15 causes the telescopic connecting rod 19 to shorten under the action of the return spring, causing the insert rod 20 to pass through the corresponding through hole and insert into the slot 21, completing the fixation on the circular plate 14, thus completing the fixation on the connecting shaft 13, and further completing the fixation on the position of the main body 1. Through the above operations, it is easy to adjust the main body 1 to a horizontal or vertical position to adapt to the connection requirements of different wires and effectively improve adaptability.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
