This structure can make full use of the space of the cable tray main body, so that it can adapt to the separated arrangement of various different cables and has better applicability.

[0004] The above-mentioned cable tray does not have the function of separating the upper half of the tray from the lower half of the tray. When a specific section of the cable needs to be repaired, it needs to be disassembled as a whole, and the cables passing through it cannot be easily removed from the tray, which makes maintenance inconvenient. Utility Model Content

[0005] The utility model aims to provide an extruded cable tray to solve the technical problem that the existing cable trays mentioned in the above background technology cannot separate the upper half of the cable tray from the lower half of the cable tray, which is inconvenient to maintain.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cable bridge formed by extrusion and drawing comprises an upper bridge and a lower bridge formed by extrusion and drawing, wherein two sets of side plates are fixedly installed on the upper surface of the lower bridge, an embedded groove is opened at one end of the side plate, an elastic plate is detachably installed in the embedded groove, and a triangular block is fixedly installed at one end of the elastic plate.

[0008] Among them, the side plate of the lower bridge frame can be inserted into the inner side of the upper bridge frame, and at the same time, the triangular block of the lower bridge frame will be pressed into the inclined sliding surface and bounced into the fitting opening through the elastic plate. The inclined sliding surface is opened at both ends of the inner side of the upper bridge frame, and the fitting opening is opened at one end of the upper bridge frame and is connected with the inclined sliding surface.

[0009] A quick-release mechanism is installed on the upper surface of the upper bridge frame for disassembly, and the quick-release mechanism can be rotated and pushed into the fitting opening.

[0010] As a preferred solution of the utility model, the triangular block fitted into the fitting opening can make the elastic plate fit with the inclined sliding surface.

[0011] As a preferred solution of the utility model, a transverse plate is fixedly installed between the two groups of side plates, and a cable separator is fixedly installed on the lower surface of the upper bridge frame. The cable separator can touch the upper surface of the transverse plate and form four groups of cable combing ports.

[0012] As a further preferred embodiment of the present invention, the triangular block can be pressed into the embedded groove by the elastic plate, and the triangular block can be removed from the fitting opening.

[0013] As a preferred solution of the utility model, the quick-release mechanism includes a Z-shaped plate, which is detachably mounted on the upper surface of the upper bridge frame. Connecting columns are mounted between multiple groups of Z-shaped plates in a damped rotation manner, and a C-shaped top column is fixedly mounted on the outer surface of the connecting column.

[0014] As a further preferred embodiment of the present invention, the C-shaped top column can be rotated to be flush with the fitting opening through the connecting column, and can be inserted into the fitting opening to touch one end of the triangular block.

[0015] Compared with the prior art, the beneficial effects of the extruded and drawn cable tray of the utility model are:

[0016] 1. When in use, the cables can be arranged in the cable separator plate first, and the two sets of side plates of the lower bridge frame are inserted into the inner side of the upper bridge frame. The triangular blocks on both sides of the side plates will touch the inclined sliding surface together, and as the side plates are continuously inserted, the triangular blocks are pressed by the elastic plates to shrink into the inward grooves. The sliding of the triangular blocks in the inclined sliding surface can also provide a guide for the insertion of the lower bridge frame. After the side plates are fully inserted into the upper bridge frame, the triangular blocks will be flush with the fitting openings, so that the triangular blocks will bounce into the fitting openings through the elastic plates, thus completing the operation of splicing the upper bridge frame and the lower bridge frame. The cable separator plates in the spliced ​​upper bridge frame will touch the upper surface of the horizontal plates in the lower bridge frame at the same time, so as to achieve the operation of enclosing the cables in the cable separator plates.

[0017] 2. When it is necessary to inspect and repair the cables in a specific section, it is only necessary to rotate and press the multiple groups of C-shaped top columns into the fittings through the connecting columns in the corresponding upper bridge, and push the multiple groups of triangular blocks out from the fittings into the embedded grooves, thereby releasing the locking force between the upper bridge and the lower bridge. The personnel can remove the lower bridge from the upper bridge by external force, and expose the cables in the cable partition plate of the upper bridge for inspection and maintenance. In the process of disassembling and assembling the lower bridge, the personnel do not need to use auxiliary tools, so that the upper bridge and the lower bridge can be quickly disassembled and assembled, which helps to reduce maintenance time and improve overall work efficiency.
