TECHNICAL FIELD

[0001] The utility model relates to cable bridge technical field, concretely is a dustproof corrosion -resistant plug -in cable bridge. BACKGROUND

[0002] Cable bridge is mainly used for supporting, protecting and guiding cable line, usually divided into three kinds of groove type, tray type and ladder type, can provide a variety of combination modes according to different wiring needs.Most of the cable bridges on the market are integrated or assembled by screw connection.The integrated bridge is not flexible enough during transportation and installation, and the size is fixed, which is difficult to adapt to the laying needs of complex lines.The bridge connected by screws has stronger flexibility.

[0003] But the bridge connected by screws needs a lot of manual operation, and the assembly process takes a long time, and because it is exposed to the external environment for a long time, the screws are prone to rust or looseness, which causes the bridge to be not firmly connected and affects the overall stability.The screw hole processing may cause dust accumulation or water ingress, and even be difficult to remove after long-term rust.

[0004] Therefore, a dustproof corrosion -resistant plug -in cable bridge is needed to solve the above technical defects. CONTENT OF THE UTILITY MODEL

When connected, the pins on the top of the first bridge are aligned with the guide sheets on the top of the second bridge and are slid and embedded. When the pin arc surface presses the positioning ball, the positioning ball slides at the pin under the compression of the spring until the hook on the tip of the pin is buckled into the buckle hole. The spring rebounds, and at this time, the positioning ball is also embedded in the ball groove, completing the connection and positioning of the first bridge and the second bridge. When disassembled, only the compression rod needs to be pulled out from the outside, and at this time, the positioning ball is separated from the ball groove. The pin is pulled back to release the connection between the first bridge and the second bridge. The bridge can be quickly assembled and disassembled, and can be connected without tools. The problem of bridge dependence on screws is solved, the construction time is reduced, the labor cost is reduced, and the influence of screw loosening or rust on the stability of the bridge connection is avoided.
