[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-6 , the utility model provides a technical solution:

[0026] Example 1:

[0027] A trapezoidal cable tray comprises a bracket 1 and a bracket 2, wherein a working structure is provided on one side of the bracket 1;

[0028] The working structure includes an adjustment mechanism 3 and a disassembly mechanism 4;

[0029] The adjustment mechanism 3 includes a guide rod 1 301, a movable plate 1 302, a cross arm 303, a fixing bolt 304, and a guide rod 2 305. The outer wall of the guide rod 1 301 is slidably connected to the inner wall of the movable plate 1 302. The top of the movable plate 1 302 is connected to the bottom of the cross arm 303. The inner wall of the cross arm 303 is threadedly connected to the outer wall of the fixing bolt 304. The inner side of the cross arm 303 is connected to both ends of the guide rod 2 305. The outer wall of the guide rod 2 305 is slidably connected to the movable plate 2 306. The top of the movable plate 2 306 is fixedly mounted with a clamping plate 307.

[0030] In this embodiment, there are two guide rods 301, which are symmetrically distributed inside the bracket 1 and the bracket 2, respectively. There are seven cross arms 303, which are symmetrically distributed between the bracket 1 and the bracket 2, respectively. This allows the position of the cross arms 303 to be quickly and conveniently adjusted, thereby enabling better use.

[0031] Furthermore, there are fourteen fixing bolts 304 symmetrically distributed on the inner walls of the seven cross arms 303 . A movable groove is provided on the top of each cross arm 303 , and the bottom of the second movable plate 306 is slidably connected to the inner wall of the movable groove, thereby enabling quick and convenient adjustment of the spacing between the multiple cross arms 303 , thereby better securing the cables.

[0032] Furthermore, a spring 1 is fixedly installed between one side of the movable plate 2 306 and the inner wall of the movable groove. The number of the clamping plates 307 is fourteen, and the clamping plates 307 are symmetrically distributed on the top of the seven cross arms 303, so that the cables can be clamped and fixed quickly and conveniently, and can be used better.

[0033] When it is needed, the operator places the cable tray to the required position, and the two cable trays can be connected and fixed to each other through the disassembly and assembly mechanism 4. When the cable needs to be fixed, the operator pulls the clamping plate 307 to move the movable plate 2 306 to slide on the guide rod 2 305, and at the same time squeezes the spring 1. At this time, the cable is placed on the cross arm 303, and the clamping plate 307 is released. The clamping plate 307 is reset by the elastic force of the spring 1, and the cable can be clamped and fixed to prevent the cable from being scattered during use. When the indirection between multiple cross arms 303 needs to be adjusted, the cross arm 303 and the movable plate 1 302 can be moved by rotating the fixing bolt 304. The movable plate 1 302 can be pulled out by the movement of the fixing bolt 304, thereby canceling the limit fixation of the cross arm 303. At this time, the cross arm 303 is pulled to move and the movable plate 1 302 slides on the guide rod 1 301, thereby adjusting the indirection between multiple cross arms 303. When the adjustment is completed, the fixing bolt 304 is rotated to insert it into the guide rod 1 301 to complete the fixation.

[0034] Example 2:

[0035] Based on the first embodiment, the disassembly and assembly mechanism 4 includes a mounting plate 401, an adjustment box 402, a limiting rod 403, and a blocking plate 404. One end of the mounting plate 401 is connected to one end of the bracket 1. The inner wall of the adjustment box 402 is slidably connected to the outer wall of the limiting rod 403. The outer wall of the limiting rod 403 is connected to the inner wall of the blocking plate 404.

[0037] Further, the support one 1 and the support two 2 are connected with the two ends of the guide rod one 301, and one side of the support one 1 and the support two 2 is connected with one end of the adjusting box 402.

[0038] When it is needed to use, the operator places the cable bridge at the position needed, the cable can be quickly and conveniently clamped and fixed by the adjusting mechanism 3, the spacing between the cross arms 303 can be quickly and conveniently adjusted, and then it can be better used, when it is needed to connect and fix the two cable bridges with each other, the operator inserts the mounting plate 401 of one cable bridge into the limiting groove in the other cable bridge, the limiting rod 403 is moved by being extruded as the mounting plate 401 is inserted, the blocking plate 404 is moved by the movement of the limiting rod 403, the spring two is extruded by the movement of the blocking plate 404, and as the mounting plate 401 is continuously inserted, the limiting rod 403 can be inserted into the limiting hole formed in one side of the mounting plate 401, and then the mounting plate 401 can be limited and fixed, so that the two cable supports can be connected and fixed with each other, when it is needed to disassemble, the limiting rod 403 is moved by being pulled, and then the limiting and fixing of the mounting plate 401 can be cancelled, and then the two cable supports can be separated, so that the operator can use it more conveniently.
