Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a wire threader. Background Technology

[0002] Cable pullers help power cables (such as copper cables) to be quickly and accurately threaded into conduits or cable trays. Traditional manual cable pulling methods require workers to repeatedly adjust the position and angle of the cables, which is time-consuming, labor-intensive, and prone to errors. Cable pullers, with their unique design, can easily guide the cables to be aligned and threaded into the target position, significantly reducing the time and labor costs required for cable pulling.

[0003] Currently used cable pullers do not have the function of cleaning the connecting wires when recycling them. In power engineering, the surface of the connecting wires may be contaminated with mud, dust or other impurities when passing through pipes. These impurities not only affect the appearance of the connecting wires, but more importantly, some impurities may affect the performance of the connecting wires. Utility Model Content

[0004] The purpose of this invention is to provide a threader to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a threader, comprising a threader body and a fixing rod bolted to one side of the surface of the threader body, and further comprising:

[0006] A threading ring rotates on the inner wall of a fixed rod. A friction-reducing roller is rotatably connected to the inner wall of the threading ring. An iron ring is bolted to one side of the surface of the threading ring, and a mounting plate is bolted to one side of the surface of the fixed rod.

[0007] A positioning mechanism is provided on one side of the mounting plate. A connecting frame is bolted to one side of the surface of the mounting plate. A mounting sleeve is bolted to the top of the connecting frame. A cleaning ring is bolted to one side of the surface of the mounting sleeve. A cleaning sleeve is provided inside the mounting sleeve. A limit mechanism is provided on one side of the mounting sleeve.

One side of the surface of the movable plate is slidably connected to the inner wall of the storage box. A pressure plate is bolted to one side of the surface of the movable plate. A magnet is provided on the top of the movable plate.

[0009] Preferably, the limiting mechanism includes a connecting rod that slides on one side of the surface of the mounting sleeve and a lever that is hinged to one side of the surface of the connecting rod. One end of the surface of the connecting rod is bolted to a limiting disc. A second compression spring is fixedly connected to one side of the inner wall of the mounting sleeve, and the other end of the surface of the second compression spring is fixedly connected to one side of the surface of the limiting disc.

[0021] 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.

[0022] Please see Figure 1-5 As shown, a thread threader includes a thread threader body 1. A fixing rod 2 is bolted to one side of the surface of the thread threader body 1. A threading ring 3 is rotatably connected to the inner wall of the fixing rod 2. An anti-friction roller 4 is rotatably connected to the inner wall of the threading ring 3. There are six anti-friction rollers 4, which are evenly distributed on both sides of the inner wall of the threading ring 3. When the connecting wire in the thread threader body 1 passes through the threading ring 3, the wear of the connecting wire in the thread threader body 1 can be reduced under the action of the anti-friction rollers 4. An iron ring 5 is bolted to one side of the surface of the threading ring 3. A mounting plate 6 is bolted to one side of the surface of the fixing rod 2. A positioning mechanism 7 is provided on one side of the mounting plate 6. The positioning mechanism 7 works in conjunction with the iron ring 5. When the internal parts of the positioning mechanism 7 move to the appropriate position, it can position the iron ring 5, thereby preventing the threading ring 3 from rotating easily. A connecting frame 8 is bolted to one side of the surface of the mounting plate 6. A mounting sleeve 9 is bolted to the top of the connecting frame 8. A cleaning ring 10 is attached to one side of the surface of sleeve 9. A cleaning sleeve 11 is installed inside the mounting sleeve 9. The cleaning sleeve 11 can be inserted into the interior of the mounting sleeve 9. The two sides of the surface of the cleaning sleeve 11 are arc-shaped, and the two sides of the inner wall of the mounting sleeve 9 are also arc-shaped. This design facilitates the calibration of the insertion angle of the cleaning sleeve 11. The connecting wire in the threader body 1 can pass through the inner cavity of the cleaning sleeve 11. A limiting mechanism 12 is provided on one side of the mounting sleeve 9. When the internal parts of the limiting mechanism 12 move to the appropriate position, they can enter the inner wall of one side of the cleaning sleeve 11. This action can prevent the cleaning sleeve 11 from easily detaching from the interior of the mounting sleeve 9. During the process of retrieving the connecting wire in the threader body 1, the cleaning ring 10 can perform preliminary cleaning of the impurities on the surface of the connecting wire in the threader body 1. When the connecting wire in the threader body 1 continues to be retrieved, the cleaning sleeve 11 can perform secondary cleaning.

[0023] The positioning mechanism 7 includes a storage box 71. The bottom of the storage box 71 is bolted to the top of the mounting plate 6. A first compression spring 72 is fixedly connected to the bottom of the inner wall of the storage box 71. A movable plate 73 is fixedly connected to the other end of the surface of the first compression spring 72. One side of the surface of the movable plate 73 is slidably connected to the inner wall of the storage box 71. The inner wall of the storage box 71 is square and the cross-section of the first compression spring 72 is square. This design can prevent the movable plate 73 from rotating. A pressure plate 74 is bolted to one side of the surface of the movable plate 73. Pulling down the pressure plate 74 can lower the movable plate 73. When the movable plate 73 lowers, the first compression spring 72 can be compressed. A magnet 75 is provided on the top of the movable plate 73. When the movable plate 73 lowers, the magnet 75 can lower. When the magnet 75 lowers to the appropriate position, it can release the adsorption on the iron ring 5. Under this action, the positioning of the threading ring 3 can be released.

[0024] The limiting mechanism 12 includes a connecting rod 121. One side of the surface of the connecting rod 121 is slidably connected to one side of the surface of the mounting sleeve 9. A lever 122 is hinged to one side of the surface of the connecting rod 121. The lever 122 has a hollow design. One end of the surface of the connecting rod 121 is bolted to a limiting disc 123. A second compression spring 124 is fixedly connected to one side of the inner wall of the mounting sleeve 9. The other end of the surface of the second compression spring 124 is fixedly connected to one side of the surface of the limiting disc 123. When the lever 122 rotates, it can drive the connecting rod 121 to move. When the connecting rod 121 moves, it can drive the limiting disc. When the limiting plate 123 moves, the second compression spring 124 is compressed. When the limiting plate 123 moves to the appropriate position, it can release the obstruction to the inside of the mounting sleeve 9. Under this action, it is easy for the cleaning sleeve 11 to be inserted into the inside of the mounting sleeve 9. When the cleaning sleeve 11 is inserted into the inside of the mounting sleeve 9, the lever 122 is rotated in the opposite direction. Under this action, the tension on the connecting rod 121 can be released. Under the action of the second compression spring 124, the limiting plate 123 can quickly return to its original position and enter the inner wall on one side of the cleaning sleeve 11. Under this action, the cleaning sleeve 11 can be prevented from moving easily.

[0025] Working principle: When cables need to be passed through pipes, the connecting wire in the main body 1 is passed through the threading ring 3 and the mounting sleeve 9. Then, rotating the placement frame in the main body 1 extends the connecting wire inside the main body 1, allowing it to pass through the pipe and connect to the cable. Reversing the placement frame in the main body 1 retracts the connecting wire, which then pulls the cable through the pipe. When the surface of the connecting wire in the main body 1 can no longer contact the anti-friction roller 4 during retraction, pull down... When the pressure plate 74 descends, it causes the movable plate 73 to descend, which in turn compresses the first compression spring 72. Simultaneously, the descent of the movable plate 73 causes the magnet 75 to descend as well. When the magnet 75 reaches the appropriate position, it releases its contact with the iron ring 5, thus releasing the positioning of the threading ring 3. Then, rotating the threading ring 3 changes the position of the friction-reducing roller 4. After the position of the friction-reducing roller 4 is adjusted according to the connecting wires in the threader body 1, the tension on the pressure plate 74 is released, and the first compression spring... Under the action of 72, the moving plate 73 can drive the magnet 75 to quickly return to its original position. Under this action, the magnet 75 can be attracted to the surface of the iron ring 5 again. Under this action, the threading ring 3 can be prevented from rotating. Since the connecting wire in the threader body 1 passes through the pipe, the surface of the connecting wire in the threader body 1 may be covered with impurities. When the connecting wire in the threader body 1 is recovered, it can pass through the inside of the cleaning ring frame 10. Under the action of the cleaning ring frame 10, the surface of the connecting wire in the threader body 1 can be initially cleaned. Then, the connecting wire in the threader body 1 can continue to be recovered by passing through the cleaning ring frame 10. The inner cavity of the cleaning sleeve 11 can perform secondary cleaning on the surface of the connecting wire in the main body 1 of the threader under the action of the cleaning sleeve 11. When the cleaning sleeve 11 needs to be replaced after long-term use, rotate the dial plate 122. When the dial plate 122 rotates, it can drive the connecting rod 121 to move. Then, the movement of the connecting rod 121 can drive the limiting plate 123 to move. When the limiting plate 123 moves, it can compress the second compression spring 124. Then, when the limiting plate 123 moves to the appropriate position, it can be moved out of the inner wall on one side of the cleaning sleeve 11. Then, the cleaning sleeve 11 can be pulled out from the inside of the mounting sleeve 9.
