Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a cable tray that is convenient for disassembly, assembly and maintenance. Background Technique

[0002] Cable trays are mainly used to lay computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. Especially in large office buildings, financial commercial buildings, hotels, venues and other buildings where information points are dense, in addition to using floor grooves and in-wall pipe burying methods for cable laying, cable trays are widely used in vertical shafts and ceiling ceilings in the house. Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cantilever arms and installation accessories, etc. The cable trays in buildings can be erected independently or laid on various building and pipe gallery brackets.

[0003] At present, the existing cable trays generally consist of a shell and a cover plate. The cover plate and the shell are connected by bolts. When workers need to replace or repair the cables, there is a defect that it is not convenient to disassemble. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable tray that is convenient for disassembly, assembly and maintenance, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cable tray that is convenient for disassembly, assembly and maintenance includes a cable tray body and a cover plate detachably arranged on the cable tray body. On both sides of the middle part of the bottom end face of the cover plate, guiding columns are symmetrically arranged. On the bottom end faces of the cover plate on both sides of the guiding columns, reinforcing columns are symmetrically arranged. On the left and right outer end faces of the cover plate, a number of uniformly distributed connecting seats are symmetrically arranged. An assembly part is hinged to the connecting seat. A plurality of assembly grooves are formed in the bottom end face of the assembly part. Driving springs are arranged in the assembly grooves. A driving block is arranged at the bottom of the assembly part, and a driving pull ring is installed on the driving block.

[0007] As a preferred technical solution of the utility model, a connecting plate integrally formed with the cable tray body is arranged on the top of the cable tray body. A guiding groove for inserting the guiding column is formed in the top end face of the connecting plate. Reinforcing grooves for inserting the reinforcing columns are formed through the connecting plates on both sides of the guiding groove.

[0008] As a preferred technical solution of the utility model, the length of the guiding column is greater than the length of the reinforcing column.

[0009] As a preferred technical solution of the utility model, fixed ring hooks corresponding to the driving pull rings one by one and capable of limiting the driving pull rings are arranged on the outer end faces of both sides of the cable tray body.

[0010] As a preferred technical solution of the present utility model, one end of the driving spring is fixedly connected to the inner side wall of the assembly groove, and the other end of the driving spring is fixedly connected to the top end face of the driving block.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] During installation, first align the guiding posts on the cover plate with the guiding grooves on the bridge body for insertion. When the guiding posts are inserted into the guiding grooves, the reinforcing posts on the cover plate are inserted into the reinforcing grooves on the bridge body accordingly, completing the preliminary connection between the cover plate and the bridge body. Then, pull the driving pull ring towards the end away from the assembly groove. While pulling, the driving spring undergoes elastic deformation. Since the fitting is hinged to the connecting seat, the staff rotates the driving pull ring outwards while pulling it, thereby driving the fitting to rotate outwards. Finally, pass the driving pull ring through the bottom of the fixed ring hook, so that the driving pull ring is clamped inside the fixed ring hook. Under the elastic action of the driving spring, the driving spring rebounds to drive the driving block and the driving pull ring to reset, thereby tightly locking the driving pull ring inside the fixed ring hook, further fixedly connecting the cover plate and the bridge body. Moreover, the connection between the installed cover plate and the bridge body is firm and reliable. When the staff needs to replace or repair the cable, they only need to reverse the above operations to complete the disassembly of the cover plate, thereby replacing or repairing the cable inside the bridge body, greatly improving the work efficiency. The structure of the present utility model is simple and the operation is convenient. It can realize the rapid installation, fixation and disassembly of the cover plate without using bolts and tools, effectively reducing the labor intensity of the staff and avoiding the thread slipping between the bolts and the installation screw holes caused by frequent screwing of the bolts, which affects the installation stability of the cover plate.
