This results in the need to adjust the position of the installation accessories when assembling them, and the installation accessories are large in size. In addition, multiple installation accessories are connected end to end, which makes it more difficult to adjust the position of the installation accessories. Therefore, it is necessary to provide a cable tray that is easy to construct to solve the above technical problems. Utility Model Content

[0003] The utility model aims to provide a cable bridge which is easy to construct, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A cable bridge that is easy to construct, comprises a bridge, a bridge cover, a connecting piece, a fastening bolt and a bracket, wherein the top ends of several of the bridges are slidably plugged with bridge covers, the heads and tails of several of the bridges are fixedly connected with connecting pieces by fastening bolts, the tops of the brackets are provided with several connecting bolts, the bottom ends of the brackets are symmetrically fixed with support arms, the tops of the two support arms are fixedly installed with mounting seats, the bottom ends of the two mounting seats are installed with limiting components, the limiting components comprise plug-in sockets, the four plug-in sockets are respectively fixedly installed at the four corners of the upper surface of the mounting seats, the four plug-in sockets are rotatably connected to a rotating plate, the four plug-in sockets are rotatably connected to a connecting rod, and the connecting rod is fixedly connected to the rotating plate.

[0006] A further improvement of the technical solution of the utility model is that: at present, when installing a cable bridge, the bracket and the bracket arm are mostly pre-fixed at a fixed distance, and then the installation accessories are placed on the bracket and the bracket arm, and then they are connected by bolts. The bolt mounting holes on the installation accessories and the bracket arm are all reserved in advance, which results in the need to adjust the position of the installation accessories during assembly, and the installation accessories are large in size. In addition, multiple installation accessories are connected end to end, which makes it more laborious to adjust the position of the installation accessories. In this solution, the staff first installs the bracket according to the preset spacing through connecting bolts, and then assembles several bridge frames and bridge frame covers. After that, the assembly is placed on the bracket arm, and then the end to end connection of multiple bridge frames is achieved through connecting plates and fastening bolts. Subsequently, the lightweight slot on the bridge is inserted into the corresponding socket, and then the rotation of the rotating plate is realized through the transmission of the limiting component, and the rotation direction of the four rotating plates are all synchronously rotated inward, so that the bridge is quickly restricted by the rotating plate, and then the installation of the bridge is realized. The setting of the limiting component can quickly perform positioning and plug-in restrictions, which increases the installation accuracy and speed of the bridge. The larger lightweight slot can facilitate the plug-in cooperation of the socket, so as to quickly realize the installation of the bridge. In addition, the synchronously rotating limiting component can quickly limit the position of the bridge, which increases the speed of assembly of the device, facilitates the disassembly and assembly of the device by the staff, increases the convenience of the device during installation and maintenance, can shorten the disassembly and assembly time of the device, and is more convenient for the staff to use.

[0007] The above technical solution is adopted, in which a plurality of lightweight grooves are evenly spaced at the bottom of the bridge.

[0008] A further improvement of the technical solution of the utility model is that the lightweight groove setting on the bridge can reduce the weight of the bridge itself, reduce the weight of the bracket and the support arm, and in addition, the lightweight groove setting on the bridge can reduce the production cost of the bridge.

[0010] A further improvement of the technical solution of the utility model is that when the bridge frame is plugged into the socket through the lightweight groove, the transmission wheel starts to rotate, and the diagonally arranged rotating gear is rotated through the transmission of the transmission belt. As the rotating gear rotates, the rotating plate rotates synchronously. As the rotating plate rotates, the four rotating plates will rotate toward the center to achieve card-connected restriction with the bridge frame, thereby increasing the quickness of the bridge frame restriction.

[0011] The above technical solution is adopted, in which the two transmission wheels are arranged diagonally.

[0012] A further improvement of the technical solution of the utility model is that the diagonally arranged transmission wheels can make the four rotating gears rotate inward synchronously, so that the rotating plate fixedly connected to the rotating gears follows the rotation, and then the position of the bridge is limited by the rotating plate.

[0013] The above technical solution is adopted, in which one end of the bottom of the mounting seat is rotatably connected to a hand wheel, and one end of the hand wheel passes through the side wall of the fixing seat and is fixedly connected to one side of one of the transmission wheels.

[0014] A further improvement of the technical solution of the utility model is that the setting of the hand wheel makes it convenient for the staff to rotate the transmission wheel, thereby driving the rotating gear to rotate the rod through the transmission wheel, increasing the convenience of using the limiting component, thereby better using the device.

[0015] The above technical solution is adopted, in which the socket is plugged into and matched with the lightweight slot on the bridge.

[0016] A further improvement of the technical solution of the utility model is that the plug-in cooperation between the plug-in socket and the lightweight slot can increase the convenience of installing the bridge, so that the device can be installed better.

[0017] The above technical solution is adopted, in which a plurality of through slots are equidistantly arranged on the bracket.

[0018] A further improvement of the technical solution of the utility model is that the through slot arrangement on the bracket can reduce the weight of the bracket itself.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
