[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] This application provides a cable tray elbow structure, which is mainly used to solve the problem that the shape and angle cannot be adjusted according to actual engineering needs, making the elbow unable to adapt to various engineering environments when used, limiting its application scope, and provides the following technical solutions, which will be described in detail below:

[0027] Example 1:

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, in some embodiments, it includes a first bridge 1, the two ends of the first bridge 1 are symmetrically connected to the second bridge 2, the connection between the second bridge 2 and the first bridge 1 is provided with an adjustment mechanism 3 for adjustment, the first bridge 1 is provided with a restraining mechanism 4 for restraining the cable, and further includes a mounting mechanism 5 provided at the outer bottom of the first bridge 1, the adjustment mechanism 3 includes an adjustment plate 301 fixedly mounted on the side of the second bridge 2, an adjustment slot 302 is provided in the middle of the adjustment plate 301, and a groove 302 is provided between the inside of the adjustment slot 302 and the first bridge 1. The limiting member 6 includes a screw 601 fixed to the side of the first bridge 1, the screw 601 slides in the adjustment groove 302 and the end of the screw 601 away from the first bridge 1 is threadedly connected to a nut 602, the end of the nut 602 abuts against the side of the adjustment plate 301, and an adjustment scale 303 is provided on the top surface of the adjustment plate 301. The adjustment range of the adjustment scale 303 is 0 degrees to 180 degrees. The measuring mechanism includes a measuring seat 701 fixed to the side of the first bridge 1, and a measuring scale 702 is provided in the middle of the side of the measuring seat 701.

[0029] Specifically: the second bridge 2 is connected by symmetrical rotation at both ends of the first bridge 1, and is adjusted by the adjustment mechanism 3, so that the angle of the bend can be flexibly adjusted according to actual needs, thereby improving the adaptability of the cable bridge bend structure to different engineering environments. The adjustment mechanism 3 can also better meet the requirements for different directions during cable wiring, making cable laying more flexible.

[0030] The working principle here is: when it is necessary to adjust the angle of the cable bridge bend, the staff first loosens the nut 602 so that the nut 602 no longer tightly contacts the side of the adjustment plate 301. At this time, the screw 601 can slide freely in the adjustment slot 302. Since the first bridge 1 is symmetrically connected to the second bridge 2 at both ends, the staff can rotate the second bridge 2 according to actual needs to change the angle of the bend. During the rotation, the screw 601 fixed on the side of the first bridge 1 will slide accordingly in the adjustment slot 302 in the middle of the adjustment plate 301. When the second bridge 2 is rotated to the desired angle, the staff can adjust it precisely through the adjustment scale 303 set on the top surface of the adjustment plate 301. To determine the angle, the range of the adjustment scale 303 is 0 degrees to 180 degrees, which can meet the needs of various angles. After determining the angle, the staff tightens the nut 602 so that the end of the nut 602 is tightly against the side of the adjustment plate 301. The friction force generated by the threaded connection between the nut 602 and the screw 601 fixes the screw 601 in the current position, thereby limiting the relative rotation between the first bridge 1 and the second bridge 2, and realizing the fixation and adjustment of the bending angle of the cable bridge. In this way, through the action of the adjustment mechanism 3, the bending structure of the cable bridge can flexibly adapt to different engineering needs, realize the setting of multiple angles, and improve its versatility and convenience in practical applications.

[0031] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, in some embodiments, the restraint mechanism 4 includes a round rod 401 and a fixed block 402 fixedly connected to the inside of the first bridge 1, a fixed splint 403 is fixedly installed on the top side of the round rod 401, a sliding rod 404 is slidably connected to the inside of the fixed block 402, a spring 405 is sleeved on the middle of the sliding rod 404, and a movable splint 406 is fixedly connected to the end of the sliding rod 404, and a circular plate 407 is fixedly installed on the end of the sliding rod 404 away from the movable splint 406, and the circular plate 407 is located at the fixed The outer side of the fixed block 402 and the inner part of the fixed block 402 are provided with a device groove 408 corresponding to the position of the spring 405, and the end of the spring 405 is fixed to the inner wall of the device groove 408. The end of the spring 405 away from the circular plate 407 abuts against the middle of the slide rod 404. The working principle here is: under normal conditions, the spring 405 is in a compressed state, applying an elastic force to the slide rod 404. Under the action of the spring 405, the slide rod 404 drives the movable splint 406 to the fixed splint 403 After releasing the circular plate 407, the elastic force of the spring 405 will cause the slide bar 404 and the movable splint 406 to return to their initial positions so as to carry out the next cable restraint operation. In this way, the restraint mechanism 4 can effectively fix and restrain the cable, and it is also convenient for the installation and removal of the cable.

[0032] Example 2:

[0033] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0034] like Figure 1 、 Figure 6As shown, in some embodiments, the mounting mechanism 5 includes a mounting frame 501 fixed to the outer bottom of the first bridge 1, the mounting frame 501 is arranged to be U-shaped and mounting plates 502 are fixedly installed on the top of both ends of the mounting frame 501, and four mounting holes 503 are arranged on the top of the mounting plate 502. The working principle here is: the main function of the mounting mechanism 5 is to fix the cable bridge bend structure at the installation position. During installation, the staff first aligns the U-shaped opening of the mounting frame 501 with the support structure of the installation position, and then uses bolts or other fixings to connect the mounting plate 502 to the support structure of the installation position through the four mounting holes 503 set on the top of the mounting plate 502. The setting of the mounting holes 503 makes the installation process more convenient and accurate, and can ensure that the mounting frame 501 can be firmly fixed on the support structure. When the bolts or other fixings pass through the mounting holes 503 and are tightened, a stable connection is formed between the mounting frame 501 and the support structure, thereby fixing the entire cable bridge bend structure at the desired position, providing reliable support for the laying of cables.

[0035] Working step 1: When adjusting the bend angle, the staff first unscrews the nut 602 in the adjustment mechanism 3 so that the screw 601 can slide in the adjustment slot 302 of the adjustment plate 301. Then, according to actual needs, the second bridge 2 is rotated. At this time, the screw 601 moves in the adjustment slot 302. When the second bridge 2 is rotated to the required angle, it is accurately confirmed by the adjustment scale 303 on the adjustment plate 301. By rotating the adjustment scale 303 so that the adjustment scale 303 is aligned with the measurement scale in the middle of the side of the measuring seat 701, it can be judged how many degrees are adjusted. Finally, tighten the nut 602 to make the second bridge 2 rotate to the required angle. The end of the nut 602 contacts the side of the adjustment plate 301, fixing the relative positions of the first bridge frame 1 and the second bridge frame 2 to achieve the adjustment of the bending angle, and then using the mounting mechanism 5. During installation, the staff first aligns the U-shaped opening of the mounting frame 501 with the support structure of the installation position, and then uses bolts or other fasteners to connect the mounting plate 502 to the support structure of the installation position through the four mounting holes 503 set on the top of the mounting plate 502. The setting of the mounting holes 503 makes the installation process more convenient and accurate, and can ensure that the mounting frame 501 can be firmly fixed on the support structure.

[0036] Working step 2: A stable connection is formed between the mounting frame 501 and the supporting structure, thereby fixing the entire cable tray bend structure in the required position, providing reliable support for the laying of the cable. Then the cable can be passed through the first bridge 1 and the second bridge 2. When the cable needs to be constrained, the staff places the cable between the fixed splint 403 and the movable splint 406. Due to the elastic force of the spring 405, the movable splint 406 will exert a certain pressure on the cable, clamping the cable between the fixed splint 403 and the movable splint 406, thereby realizing the constraint and fixation of the cable. When the cable needs to be removed, the staff pulls the circular plate 407 outward, and the circular plate 407 drives the slide bar 404 to overcome the elastic force of the spring 405 and move outward. The slide bar 404 drives the movable splint 406 away from the fixed splint 403. At this time, the distance between the fixed splint 403 and the movable splint 406 increases, and the cable can be easily removed.

[0037] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
