The two cover plates 2 are hinged by the pin in the sleeve 21, and the two cover plates 2 can rotate around the pin. The side of the bottom of the cover plate 2 away from the sleeve 21 is fixedly connected with an L-shaped slot 22, and the tops of the inner walls on both sides of the bridge slot 1 are fixedly connected with a clamping strip 11, and the clamping strip 11 is clamped inside the L-shaped slot 22. The two cover plates 2 are rotated so that the angle between the two cover plates 2 is less than 180 degrees, so that the two cover plates 2 can be placed between the two clamping strips 11, and the two The L-shaped slots 22 on each cover plate 2 correspond to the two card strips 11, and then the two cover plates 2 are unfolded to make the included angle of the two cover plates 2 equal to one hundred and eighty degrees to complete the card connection. Since the metal plate used in the trough-type cable tray is relatively thin, it has good flexibility, thereby ensuring that the card strip 11 can be smoothly inserted into the L-shaped slot 22. A positioning block 23 is fixedly connected to one side of the top of the cover plate 2 close to the sleeve 21. After the two cover plates 2 are unfolded to one hundred and eighty degrees, the positioning blocks 23 on the two cover plates 2 conflict with each other, so that the cover plates 2 cannot continue to rotate around the pin shaft, thereby achieving the purpose of fixing the two cover plates 2.

[0030] Specifically, a triangular plate 13 is fixedly connected to the corner of the inner wall of the bridge frame groove 1, and the triangular plate 13 reinforces the angle of the bridge frame groove 1 to prevent changes in the angle between the two side walls and the bottom of the bridge frame groove 1. Vertical bars 14 are fixedly connected to the two side walls of the bridge frame groove 1, and the vertical bars 14 can reinforce the two side walls of the bridge frame groove 1 to avoid the problem of bending of the two side walls of the bridge frame groove 1.
