Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe racks. They should be characterized by simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. This applies to cable trays installed outdoors.

[0003] When using existing cable trays, splicing several sections requires a large number of bolts and nuts for fixing, making the assembly process very cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0004] This utility model provides a cable tray that is easy to assemble. Its purpose is to solve the problem that when using existing cable trays, a large number of bolts and nuts are needed to fix several sections of the cable tray, making the assembly process very cumbersome, time-consuming and labor-intensive.

[0005] This utility model provides a cable tray that is easy to assemble, including a cable tray, a splicing plate installed between adjacent cable trays, a fixing plate provided on the splicing plate, a locking mechanism provided on the fixing plate, and the splicing plate and the cable tray are fixed together by clips.

[0006] Furthermore, the splicing plate has abutment plates on both sides, first through holes on the left and right sides of the abutment plates, and several second through holes on the bottom surface of the splicing plate.

[0007] By adopting the above technical solution, the setting of the backing plate prevents the fixing plate from moving up and down when it is placed under the backing plate, and the fixing plate can press the connection between the splicing plate and the cable tray tightly.

[0008] Furthermore, the tops of both sides of the cable tray and the splicing plate are curved semi-open arcs and are adapted to each other.

[0009] By adopting the above technical solution, the top of the splicing plate is screwed into the top of the cable tray, thereby locking the splicing plate to the cable tray and preventing it from being pulled out, thus improving the fastening effect.

[0010] Furthermore, the locking mechanism includes a third through hole provided on the fixing plate, a bendable limiting plate provided in the third through hole, and a fourth through hole provided on the bridge frame corresponding to the second and third through holes.

[0011] By adopting the above technical solution, when the splicing plate is placed at the junction of adjacent cable trays and the fixing plate is placed on the splicing plate, the second through hole, the third through hole and the fourth through hole correspond to each other. Then, the bending limiting plate passes through the second through hole and the fourth through hole, so that the limiting plate fits against the bottom surface of the cable tray, thereby fastening the cable tray, the splicing plate and the fixing plate.

[0012] Furthermore, the first through hole includes a first upper through hole and a first lower through hole, with the first upper through hole located above the first lower through hole.

[0013] By adopting the above technical solution, the first upper through hole and the first lower through hole can be inserted into the card, thereby further achieving the purpose of fastening the splicing plate to the cable tray.

[0015] By adopting the above technical solution, the inserting parts are inserted into the first upper through hole and the first lower through hole respectively. Under the elastic action of the card, the card can be locked in place, thereby improving the tightness of the cable tray and the splicing plate.

[0016] Furthermore, the insert portion is adapted to the first upper through hole and the first lower through hole, and the inclined plate is provided with a slot.

[0017] By adopting the above technical solution, the card can be easily inserted into the first upper through hole and the first lower through hole. At the same time, the card slot can make the upper and lower edges of the first upper through hole and the first lower through hole fit in, further limiting and fixing the splicing plate and the cable tray.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a splicing plate, where the top of the splicing plate is screwed into the top of the cable tray, to lock the splicing plate and the cable tray together, making it impossible to pull out and improving the fastening effect. At the same time, the setting of the abutment plate prevents the fixing plate from moving up and down when it is placed under the abutment plate, and the fixing plate can press the connection between the splicing plate and the cable tray tightly.

[0020] 2. In this utility model, when the splicing plate is placed at the junction of adjacent cable trays and the fixing plate is placed on the splicing plate, the second through hole, the third through hole and the fourth through hole correspond to each other. Then, the bending limiting plate passes through the second through hole and the fourth through hole, so that the limiting plate fits against the bottom surface of the cable tray, thereby fastening the cable tray, the splicing plate and the fixing plate.

[0021] 3. The card of this utility model is inserted into the first upper through hole and the first lower through hole respectively. Under the elastic action of the card, the upper and lower edges of the first upper through hole and the first lower through hole can be inserted into the card slot, which further limits and fixes the splicing plate and the cable tray, and improves the tightness of the cable tray and the splicing plate.

[0031] Reference Figure 1-5 This utility model provides an easy-to-assemble cable tray, including a cable tray 1, with splicing plates 2 installed between adjacent cable trays 1. The tops of both side walls of the cable tray 1 and the splicing plates 2 are curved semi-open arcs and are compatible with each other. The top of the splicing plate 2 is screwed into the top of the cable tray 1 to lock the splicing plate 2 and the cable tray 1 together, making it impossible to remove and improving the fastening effect.

[0032] Reference Figure 1-5 The splicing plate 2 is provided with a fixing plate 3, and the two side walls of the splicing plate 2 are provided with abutment plates 21. The left and right sides of the abutment plates 21 are provided with first through holes 22, and the bottom surface of the splicing plate 2 is provided with several second through holes 23. By setting the abutment plates 21, the fixing plate 3 cannot move up and down when placed under the abutment plates 21, and the connection between the splicing plate 2 and the cable tray 1 can be pressed tightly by the fixing plate 3.

[0033] Reference Figure 1-5 The fixing plate 3 is provided with a locking mechanism 4. The locking mechanism 4 includes a third through hole 41 on the fixing plate 3. A bendable limiting plate 42 is provided in the third through hole 41. The cable tray 1 is provided with a fourth through hole 43 corresponding to the second through hole 23 and the third through hole 41. When the splicing plate 2 is placed at the junction of adjacent cable trays 1 and the fixing plate 3 is placed on the splicing plate 2, the second through hole 23, the third through hole 41 and the fourth through hole 43 correspond to each other. Then the limiting plate 42 is bent and passes through the second through hole 23 and the fourth through hole 43, so that the limiting plate 42 fits against the bottom surface of the cable tray 1, thereby fastening the cable tray 1, the splicing plate 2 and the fixing plate 3.

[0034] Reference Figure 1-5The first through hole 22 includes a first upper through hole 221 and a first lower through hole 222. The first upper through hole 221 is located above the first lower through hole 222. The splicing plate 2 and the cable tray 1 are fixed by a card 5. The card 5 includes a fitting part 51 and a snap-in part 52. The fitting part 51 and the snap-in part 52 are parallel and connected by an inclined plate 53. The snap-in part 52 is snapped into the first upper through hole 221 and the first lower through hole 222 respectively. Under the elastic action of the card 5, the card 5 can be snapped into place, thereby improving the tightness between the cable tray 1 and the splicing plate 2.

[0035] Reference Figure 1-5 The insert 52 is adapted to the first upper through hole 221 and the first lower through hole 222. The inclined plate 53 is provided with a slot 531, which makes it easy for the card 5 to be inserted into the first upper through hole 221 and the first lower through hole 222. At the same time, the slot 531 can make the upper and lower edges of the first upper through hole 221 and the first lower through hole 222 inserted, further limiting and fixing the splicing plate 2 and the cable tray 1.

[0036] The specific implementation method is as follows: In use, the connection points of the two cable trays 1 are joined together. First, a splicing plate 2 is installed above the connection point. The semi-open arc shape at the top of the splicing plate 2 is inserted into the semi-open arc shape of the cable tray 1. Then, the splicing plate 2 is rotated inward, so that the top of the splicing plate 2 tightly fits against the inner arc-shaped surface of the top of the cable tray 1, achieving a fixing effect. Then, a fixing plate 3 is placed on the splicing plate 2, aligning the third through hole 41, the second through hole 23, and the fourth through hole 43. Then, the limiting plate 42 is bent to limit the movement. The plate 42 is attached to the bottom surface of the cable tray 1 to further enhance the fastening effect. When the fixing plate 3 is placed on the splicing plate 2, the abutment plate 21 of the splicing plate 2 can limit the fixing plate 3 to prevent the fixing plate 3 from moving up and down. Then, the snap-in part 52 of the elastic card 5 is snapped into the first upper through hole 221 and the first lower through hole 222 respectively, so that the upper and lower edges of the first upper through hole 221 and the first lower through hole 222 can be snapped into the slot 531, further improving the fastening degree between the cable tray 1 and the splicing plate 2.
