Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and in particular relates to an adjustable cable laying device for electrical engineering. Background Technology

[0002] In the field of modern electrical engineering construction, cable laying is a key link in power transmission and signal transmission. With the advancement of projects such as urban power grid transformation, cable laying scenarios are becoming increasingly complex, which puts forward higher requirements for the adjustment flexibility and adaptability of laying equipment.

[0003] Traditional cable trays typically involve threading cables through cable loops and installing multiple cable trays at the installation location to lay the cables. However, when laying cables at the corners of walls, the length of traditional cable trays is not easily adjustable. In this case, the cables can only be pulled straight to prevent them from collapsing. However, this method causes the cables to come into direct contact with the corners of the walls. Wind blowing on the cables can cause them to sway, and prolonged swaying can easily cause the cables to be worn and torn by the walls, leading to interruptions in power and signal transmission. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable cable laying device for electrical engineering. By setting an extension mechanism, specifically pulling down the unlocking block, the limiting post moves down to compress the first spring, and the locking rod disengages from the locking groove, the first locking block unlocks, grabs the unlocking block and moves the extension tube. The first locking block rotates around the rotating rod under the pressure of the quarter-circle surface of the irregular groove and compresses the spiral spring. After moving into place, the unlocking block is released, the first spring resets and the locking rod re-engages into the locking groove. This setting can flexibly adjust the length of the extension tube, which is convenient for laying cables at corners and improves the overall applicability. It solves the problem that the length of the existing traditional cable rack is not easy to adjust, and the cable is straightened by force to prevent it from collapsing, but this method is easy for the cable to be scratched by the corner of the wall.

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.

[0038] Please see Figures 1-8As shown, this utility model is an adjustable cable mounting device for electrical engineering, including a cable frame 1. The cable frame 1 includes a fixing box 11, a fixing tube 21 fixedly connected to the left side of the fixing box 11, an extension tube 22 slidingly limited to the inner wall of the fixing tube 21, a fixing box 22 fixedly connected to the left side of the extension tube 22, a cable coil 21 121 disposed above the fixing box 22, and also includes an extension mechanism 2, which is disposed at the bottom of the extension tube 22 and is used to extend and retract the extension tube 22. Two clips are disposed at the bottom of the extension tube 22. The extension mechanism 2 includes a first block 222, with a rotating rod 223 fixedly connected inside each of the two first blocks 222. The rotating rod 223 is rotatably connected to the extension tube 22. An adjustment mechanism 3 is also included, located inside the second fixing box 12, for adjusting the angle of the second cable coil 121. A cable coil 111 is fixedly connected to the top of the first fixing box 111. The inner diameters of the cable coil 111 and the second cable coil 121 are the same, and both inner coils have an arc surface. The first block 222 penetrates the bottom of the extension tube 22 and extends into it. The extension mechanism 2 includes a fixing block 221, the top of which is fixedly connected to the bottom of the extension tube 22, and the bottom of the rotating rod 223 is rotatably connected to the fixing block 221. The two first blocks 222 are symmetrically arranged, and the bottom of the fixing tube 21 has several irregularly shaped grooves 211. The adjustment mechanism 3 includes an adjustment groove 31 inside the fixed box 2 12, and a rotating shaft 32 is rotatably connected inside the fixed box 2 12. The top of the rotating shaft 32 is fixedly connected to the bottom of the cable coil 2 121, and several teeth 321 are fixedly connected to the outer surface of the rotating shaft 32. A spiral spring 224 is fixedly connected to the top of the outer surface of the rotating rod 223, and two mounting rings 225 are fixedly connected to the bottom of the inner wall of the extension tube 22. The other end of the spiral spring 224 is fixedly connected to the inner wall of the mounting ring 225, and a locking groove 226 is opened at the bottom of the locking block 1 222.The bottom of the fixed block 221 is provided with an unlocking block 23. Locking rods 231 are fixedly connected to the front and back of the top of the unlocking block 23, and the locking rods 231 are inserted into the locking grooves 226. Two guide rods 232 are fixedly connected to the top of the unlocking block 23, and two guide grooves 236 are opened at the bottom of the fixed block 221, with the guide rods 232 inserted into the guide grooves 236. A limit post 233 is fixedly connected to the center of the top of the unlocking block 23, and a spring 234 is sleeved on the outer surface of the limit post 233. Pulling down the unlocking block 23 causes the limit post 233 to move downwards, compressing the spring 234, causing the locking rods 231 to disengage from the locking grooves 226, unlocking the locking block 222. Grabbing the unlocking block 23 and moving the extension tube 22 further unlocks the locking block. The spring 222 rotates around the rotating rod 223 under the pressure of the quarter-circle surface of the irregular groove 211, compressing the spiral spring 224. After moving into position, it releases the unlocking block 23, and the spring 234 resets, causing the locking rod 231 to re-engage in the locking groove 226. This setting allows for flexible adjustment of the length of the extension tube 22, facilitating the installation of cables at corners and improving overall applicability. The bottom of the fixing block 221 has a limiting groove 235. The top end of the spring 234 is fixedly connected to the limiting post 233, and the bottom end of the spring 234 is fixedly connected to the bottom of the inner wall of the limiting groove 235. The limiting post 233 is rotatably connected to the limiting groove 235. The two locking rods 231 and the two guide rods 232 are symmetrically arranged. The inner wall of the adjusting groove 31 is fixedly connected to two limiting blocks 33, and a locking block 34 is slidably fitted between the two limiting blocks 33. The locking block 34 is inserted into several teeth 321, and two symmetrical inclined surfaces are provided on one end of the back of the locking block 34. The locking block 34 has an annular groove 341 and a slot 342 inside. The second fixing box 12 has a sliding limit fitting with a lifting rod 343. Two slots 344 are fixedly connected to the top of the outer surface of the lifting rod 343. The lifting rod 343 slides through the annular groove 341, and the two slots 344 are inserted into the slot 342. The second fixing box 12 has a lifting groove 345 inside, and the two slots 344 slide through the lifting groove 345. Pushing the lifting rod 343 upwards causes the two slots 344 to enter the lifting groove 345, releasing the locking state of the locking block 34. Adjusting the rotating shaft 32... When the teeth 321 press the locking block 34 to move its front side, the second spring 35 is compressed. After the rotating shaft 32 is released, the second spring 35 returns to its original position and pushes the locking block 34 into the space between adjacent teeth 321. After the adjustment is in place, the lifting rod 343 is released. Due to gravity, it moves down and the second locking block 344 enters the slot 342, relocking the rotating shaft 32 so that it cannot rotate. This setting can flexibly adjust the angle of the cable coil 121, and the angle of the cable can be adjusted according to the usage requirements. The front side of the locking block 34 is fixedly connected to two second springs 35, and the other end of each second spring 35 is fixedly connected to the inner wall of the adjustment groove 31.

[0039] A specific application of this embodiment is as follows: In use, first use bolts to install the front of the fixing box 11 at the desired installation position. Then, pass the cable through cable loop 111 and cable loop 121 respectively. At this time, the unlocking block 23 can be pulled down, the limiting post 233 moves down, the spring 1 234 is compressed, and at the same time, the two locking rods 231 and the guide rod 232 move down. At this time, the two locking rods 231 leave the two locking slots 226, causing the two locking blocks 1 222 to lose their lock. Then, the unlocking block 23 can be grasped and moved to the left or right. The extension tube 22 will follow the movement. During the movement of the extension tube 22, the locking block 1 222 is squeezed by the irregular groove 211, causing both locking blocks 1 222 to rotate around the rotating rod 223. When the shaft rotates, the ends of the two locking blocks 222 that are far apart will rotate toward the side that is close to each other. At the same time, the spiral spring 224 is also compressed. Since the inner wall of the irregular groove 211 is provided with a quarter-circle arc surface, when the locking block 222 loses compression during movement, the spiral spring 224 will reset the locking block 222 through its own elasticity. When the extension tube 22 moves to the appropriate position, the unlocking block 23 is released. The spring 234 pushes the unlocking block 23 upward to reset through its own elasticity. At this time, the two locking rods 231 re-enter the two locking grooves 226 to lock the two locking blocks 222. Due to the quarter-circle arc surface of the irregular groove 211, the locked locking block 222 cannot move.

[0040] When it is necessary to adjust the angle of the cable coil 121, the lifting rod 343 can be pushed upwards, causing the two locking blocks 344 to enter the lifting groove 345. At this time, the locking block 34 is unlocked, and the rotating shaft 32 can be rotated clockwise or counterclockwise. During the rotation, several teeth 321 will press the locking block 34, causing it to move forward. At this time, the two springs 35 are compressed. After the locking block 34 is released, the two springs 35 push the locking block 34 back to its original position through their own elasticity, causing it to re-enter between the two adjacent teeth 321. After adjusting to the appropriate position, the lifting rod 343 is released, and it moves downwards by its own gravity. At this time, the two locking blocks 344 will move down together into the locking groove 342. At this time, the locking block 34 is locked, and the rotating shaft 32 cannot rotate.
