Description

Technical Field

[0001] This utility model belongs to the field of conductor fixing technology, and in particular relates to insulated tension clamps. Background Technology

[0002] Insulated tension clamps are key hardware used in power lines to fix conductors and bear tension. They also have insulation protection functions, mainly used to prevent current from being conducted to the poles through the clamps, thus avoiding short circuits or leakage accidents.

[0003] Traditional insulated tension clamps typically have a fixed-length clamp plate. Since the insulated tension clamp needs to be connected to the tower when fixing the conductor, the fixed-length clamp plate can make it difficult to connect to the tower, thus requiring the use of other auxiliary structures for connection. This not only increases the difficulty of fixing the conductor, but also makes it difficult to meet different needs when fixing conductors in different areas. Utility Model Content

[0004] The purpose of this utility model is to provide an insulated tension clamp. By setting a telescopic mechanism, specifically pulling the plug rod to disengage it from the clamp hanging plate two and release the clamp hanging plate one from its fixation, the clamp hanging plate one can be pushed or pulled to adjust the length of the clamp hanging plate one and the clamp hanging plate two. This can meet different fixing requirements, so that when fixing conductors in different areas, they can be smoothly connected to the tower. This solves the problem that the setting of the fixed length of the clamp hanging plate can easily lead to difficulty in connecting to the tower.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an insulated tension clamp, comprising a wedge-shaped insulated tension clamp body, inside which two cores are inserted; and further comprising: a telescopic mechanism disposed on the outside of the wedge-shaped insulated tension clamp body, the telescopic mechanism being used to adjust the connection length with the tower pole; and a limiting mechanism disposed on the left side of the cores, the limiting mechanism being used to limit the position of the cores; the top of the wedge-shaped insulated tension clamp body is open; both the interior and the exterior of the wedge-shaped insulated tension clamp body are tapered, and the exterior of the cores is adapted to the interior of the wedge-shaped insulated tension clamp body; the inner ring of the cores has several protrusions; when the two cores are inserted into the wedge-shaped insulated tension clamp body respectively, the conductor is positioned at the center of the cores; the protrusions on the cores are used to increase friction and improve the fixing effect of the conductor.

[0007] Further, the telescopic mechanism includes two wire clamp mounting plates 1 and 2 wire clamp mounting plates 2. The first wire clamp mounting plate is disposed on the outer side of the second wire clamp mounting plate. A hexagonal bolt is inserted into the side of the second wire clamp mounting plate facing the wedge-shaped insulated tension clamp body, and the hexagonal bolt is threadedly connected to the wedge-shaped insulated tension clamp body; and

[0008] A fixing post is fixedly connected to the outside of the first wire clamp hanging plate. A plug rod is slidably connected inside the fixing post. The plug rod is used to restrict and fix the first wire clamp hanging plate and the second wire clamp hanging plate. When the hexagonal bolt is not tightened, the second wire clamp hanging plate can be rotated and adjusted on the wedge-shaped insulated tension clamp body. Hexagonal bolts with pin holes are inserted into the ends of the two first wire clamp hanging plates. Hexagonal nuts are threaded onto the hexagonal bolts with pin holes.

[0009] Furthermore, the first wire clamp mounting plate has a square groove inside, the first wire clamp mounting plate is located on the outside of the second wire clamp mounting plate, and the first wire clamp mounting plate and the second wire clamp mounting plate are in contact with each other on their respective sides.

[0010] Furthermore, the second wire clamp mounting plate has several insertion holes inside. Limiting strips are fixedly connected to the top and bottom of the side of the second wire clamp mounting plate facing the first wire clamp mounting plate, and a limiting block is fixedly connected to the outer end of the second wire clamp mounting plate. The limiting strips and the limiting block limit and support the movement of the first wire clamp mounting plate, making the first wire clamp mounting plate more stable during movement and maintaining horizontal movement. The limiting strips are L-shaped, the first wire clamp mounting plate is slidably connected to the inner side of the limiting strips, and the limiting block is slidably connected to the square groove on the first wire clamp mounting plate.

[0011] Furthermore, a limiting ring is fixedly connected to the outer surface of the insertion rod, the limiting ring is slidably connected inside the fixing column, a square strip is fixedly connected to the outer surface of the insertion rod, a spring is sleeved on the outer side of the insertion rod, the side of the spring facing the limiting ring is fixedly connected to the surface of the limiting ring, and the side of the spring away from the limiting ring is in contact with the inner wall of the fixing column.

[0012] Furthermore, the insertion rod is adapted to the insertion hole, and the diameter of the insertion rod is slightly smaller than the inner diameter of the insertion hole. The fixing post has a limiting groove adapted to the shape of the square strip on the side away from the wire clamp hanging plate. After the square strip moves to the outside of the fixing post and rotates, it is used to restrict the insertion rod.

[0013] Furthermore, the limiting mechanism includes a limiting slider fixedly connected to the outer surface of the core, and a positioning rod slidably connected inside the limiting slider. The right side of the positioning rod is fixedly connected to the left side of the wedge-shaped insulated tension clamp body. The positioning rod is used to position the core during installation. The limiting slider is inserted into the positioning rod to position and limit the core, so that the core will not deviate during movement. At the same time, this method can prevent the core from falling off before it is tightened.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a telescopic mechanism. Specifically, pulling the insert rod disengages it from the wire clamp mounting plate two, releasing the wire clamp mounting plate one from its fixation. Then, pushing or pulling the wire clamp mounting plate one adjusts the length of both the wire clamp mounting plate one and the wire clamp mounting plate two. Finally, the insert rod springs back to its original position, fixing the wire clamp mounting plate one and the wire clamp mounting plate two in place, thus completing the length adjustment. This method can meet different fixing requirements, ensuring smooth connection to the tower pole when fixing conductors in different areas.

[0016] 2.

[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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model is an insulating tension clamp, including a wedge-shaped insulating tension clamp body 1, with two cores 11 inserted inside the wedge-shaped insulating tension clamp body 1, and also including:

[0028] Telescopic mechanism 2, located on the outside of the wedge-shaped insulated tension clamp body 1, is used to adjust the connection length with the tower; and

[0029] Limiting mechanism 3 is located on the left side of core 11 and is used to limit the movement of core 11;

[0030] The wedge-shaped insulated tension clamp body 1 has an open top, and both the inside and the outside of the core 11 are tapered. The outside of the core 11 is adapted to the inside of the wedge-shaped insulated tension clamp body 1, and the inner ring of the core 11 has several protrusions.

[0031] The telescopic mechanism 2 includes two clamp mounting plates 1 21 and two clamp mounting plates 22. The clamp mounting plates 1 21 are located on the outer side of the clamp mounting plates 22. Hexagonal bolts 12 are inserted into the side of the clamp mounting plates 22 facing the wedge-shaped insulated tension clamp body 1, and the hexagonal bolts 12 are threadedly connected to the wedge-shaped insulated tension clamp body 1.

[0032] A fixing post 23 is fixedly connected to the outside of the first clamp plate 21. A sliding rod 231 is slidably connected inside the fixing post 23. The rod 231 is used to restrict and fix the first clamp plate 21 and the second clamp plate 22. Pulling the rod 231 disengages it from the second clamp plate 22, releasing the fixation of the first clamp plate 21. Then, the first clamp plate 21 is pushed or pulled to adjust its length. The rod 231 is then returned to its original position, restricting and fixing the first clamp plate 21 and the second clamp plate 22, thus completing the length adjustment. This method can meet different fixing requirements, ensuring smooth connection to the tower pole when fixing conductors in different areas.

[0033] When the hexagonal bolt 12 is not tightened, the wire clamp mounting plate 22 can be rotated and adjusted on the wedge-shaped insulated tension clamp body 1. The ends of the two wire clamp mounting plates 21 are connected to hexagonal bolts with pin holes 211, and hexagonal nuts are threaded onto the hexagonal bolts with pin holes 211. The two wire clamp mounting plates 21 are connected by the hexagonal bolts with pin holes 211, and hexagonal nuts are installed on the hexagonal bolts with pin holes 211 to complete the connection of the two wire clamp mounting plates 21.

[0034] The wire clamp mounting plate 21 has a square groove 212 inside. The wire clamp mounting plate 21 is located on the outside of the wire clamp mounting plate 22, and the wire clamp mounting plate 21 and the wire clamp mounting plate 22 are in contact with each other on their respective sides.

[0035] The wire clamp mounting plate 22 has several insertion holes 221 inside. Limiting strips 222 are fixedly connected to the top and bottom of the side of the wire clamp mounting plate 22 facing the wire clamp mounting plate 21. Limiting blocks 223 are fixedly connected to the outer end of the wire clamp mounting plate 22. The limiting strips 222 and the limiting blocks 223 limit and support the wire clamp mounting plate 21 when it moves, making the wire clamp mounting plate 21 more stable when it moves and maintaining horizontal movement.

[0036] The limiting strip 222 is L-shaped, the wire clamp hanging plate 21 is slidably connected to the inner side of the limiting strip 222, and the limiting block 223 is slidably connected to the square groove 212 on the wire clamp hanging plate 21.

[0037] A limiting ring 232 is fixedly connected to the outer surface of the insertion rod 231. The limiting ring 232 is slidably connected inside the fixed post 23. A square strip 233 is fixedly connected to the outer surface of the insertion rod 231. A spring 234 is sleeved on the outer side of the insertion rod 231. The side of the spring 234 facing the limiting ring 232 is fixedly connected to the surface of the limiting ring 232. The side of the spring 234 away from the limiting ring 232 is in contact with the inner wall of the fixed post 23. Pulling the insertion rod 231 makes it disengage from the wire clamp hanging plate 22. After the square strip 233 moves to the outside of the fixed post 23, the insertion rod 231 is rotated so that the square strip 233 disengages from the limiting groove on the front of the fixed post 23. At this time, the insertion rod 231 is restricted to prevent the insertion rod 231 from rebounding, making it convenient for the staff to push and pull the wire clamp hanging plate 21.

[0038] The insertion rod 231 is adapted to the insertion hole 221. The diameter of the insertion rod 231 is slightly smaller than the inner diameter of the insertion hole 221. The fixing post 23 has a limiting groove on the side away from the wire clamp hanging plate 21 that is adapted to the shape of the square strip 233. After the square strip 233 moves to the outside of the fixing post 23 and rotates, it is used to restrict the insertion rod 231.

[0039] The limiting mechanism 3 includes a limiting slider 31 fixedly connected to the outer surface of the core 11. A positioning rod 32 is slidably connected inside the limiting slider 31. The right side of the positioning rod 32 is fixedly connected to the left side of the wedge-shaped insulated tension clamp body 1. The positioning rod 32 is used to position the core 11 during installation. The wire is inserted from the top opening of the wedge-shaped insulated tension clamp body 1. Then, the two cores 11 are inserted into the wedge-shaped insulated tension clamp body 1 respectively. The limiting slider 31 is inserted into the positioning rod 32, thereby positioning and limiting the core 11, so that the core 11 will not deviate during movement. At the same time, this method can prevent the core 11 from falling off before it is tightened.

[0040] One specific application of this embodiment is:

[0041] In use, first adjust the lengths of the first clamp plate 21 and the second clamp plate 22 according to the required connection length with the pole. Pull the insert rod 231 to disengage it from the second clamp plate 22. The limiting ring 232 will then compress the spring 234, causing the square bar 233 to slide on the fixed post 23. Once the square bar 233 moves to the outside of the fixed post 23, rotate the insert rod 231 to disengage the square bar 233 from the limiting groove on the front of the fixed post 23. This will restrict the insert rod 231 and prevent it from springing back. Repeat the same process on the other side of the insert rod 231. Then, pull the first clamp plate 21, which will then be positioned on the two clamp plates 22. The limiting strip 222 slides within the limiting strip 222, and the limiting block 223 slides within the square groove 212 to limit the movement of the first wire clamp hanging plate 21, making the movement of the first wire clamp hanging plate 21 more stable. After the length adjustment is completed, the insertion rod 231 is rotated again so that the square strip 233 is inserted into the limiting groove on the insertion rod 231. At this time, the insertion rod 231 can rebound by the elastic force of the spring 234. Then, the same operation is performed on the other side of the insertion rod 231. Then, the first wire clamp hanging plate 21 is pulled and finely adjusted so that the insertion rod 231 is aligned with the insertion hole 221 on the second wire clamp hanging plate 22. The insertion rod 231 then springs into the insertion hole 221, thereby limiting and fixing the first wire clamp hanging plate 21 and the second wire clamp hanging plate 22, completing the length adjustment.

[0042] The second clamp plate 22 is connected to the wedge-shaped insulated tension clamp body 1 by hex bolts 12. When the hex bolts 12 are loose, the second clamp plate 22 can be rotated and adjusted. The two first clamp plates 21 are connected by hex bolts with pin holes 211, and hex nuts are installed on the hex bolts with pin holes 211 to complete the connection of the two first clamp plates 21.

[0043] Insert the conductor into the top opening of the wedge-shaped insulated tension clamp body 1, then insert the two cores 11 into the wedge-shaped insulated tension clamp body 1 respectively, and position the conductor at the center of the core 11. After installing the cores 11, insert the limiting slider 31 into the positioning rod 32 to position and limit the cores 11, preventing them from shifting during movement. The inner side of the core 11 has a protrusion at the contact position with the conductor to increase friction and improve the fixing effect. Finally, connect the end of the clamp hanging plate 21 to the tower and tighten it. The wedge-shaped insulated tension clamp body 1 is then pulled. Since the cores 11 and the wedge-shaped insulated tension clamp body 1 are tapered, the wedge-shaped insulated tension clamp body 1 will squeeze the cores 11, thus fixing the conductor.
