[0002] Cable trays play a very important role in the laying and maintenance of cable lines. They can ensure the safety, stability, cleanliness and beauty of cable lines. They mainly support and fix cables, protect cables and manage cables. Cable trays often require connecting fixing devices between the joints of cable troughs, which can improve the stability of the cable trays.

[0003] Since the fixing device for connecting the seams of cable trays and ducts has a simple structure and can only realize a single connection and fixing function, but does not have a multi-level waterproof sealing protection structure, the cable trays and ducts installed outdoors are prone to internal water seepage in rainy weather. Moreover, it is not easy to achieve positioning and fixing on the seams of the cable trays and ducts, which makes the operation of the device inconvenient and can no longer meet people's needs. Therefore, we propose a new type of fixing device for connecting the seams of cable trays and ducts to solve the above-mentioned defects. Utility Model Content
