Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge connection structure. Background Art

[0002] Cable tray is a product designed to protect cables. It is a protective shell for cables and can prevent them from being damaged by external factors. It is mainly composed of brackets, brackets and installation accessories. There are many types, such as trough type, tray type, ladder type, grid type, etc. In engineering, cable trays are very common and are often used to lay cables. It can be erected independently or attached to various buildings (structures) and pipe gallery brackets. It should have the characteristics of simple structure, beautiful shape, flexible configuration and easy maintenance. At the same time, all parts need to be galvanized and can be installed outdoors outside the building.

[0003] Among them, the tray-type cable tray is a common cable tray structure. The tray type is generally used for more and larger cables. It has the advantages of light weight and large load. General cable trays are connected by welding, but this method has some disadvantages. On the one hand, after a long service life, the welding parts will become loose and unstable. If they are not reinforced in time, the cable tray may cause safety hazards. On the other hand, due to the welding connection, if the cable tray is damaged or the cable needs to be repaired, the cable tray needs to be disassembled. Multiple cable trays welded together need to be disassembled at the same time. This process is cumbersome and inconvenient to repair.

[0004] Therefore, it is necessary to provide a cable tray connection structure to solve the above technical problems. Utility Model Content
