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

[0002] Cable tray is a structure used to support, protect and manage cables, usually used in industrial and commercial buildings. Its main function is to hang or support cables from the ground or wall to ensure the safety and reliability of the cable system. Due to weather or other influences, ordinary cable trays cannot prevent lightning strikes or electromagnetic interference, so a lightning-proof cable tray is needed to support the cables and ensure that the cable system can still be stably supported under severe weather conditions without being affected by external interference, so as to ensure the safe and reliable operation of the cable system;

[0003] However, the existing lightning protection cable tray has the following disadvantages: the cover plate on the lightning protection cable tray is usually directly covered on the side plate and connected and fixed with an ordinary locking hook, but the ordinary locking hook will become loose after a long time of use, affecting the safety of the lightning protection cable tray. Therefore, the existing lightning protection cable tray needs to be improved. Utility Model Content

[0006] Preferably, limiting plates are fixed at both ends of the cover plate, connecting pieces are provided at both ends of the side plate, and one side of the connecting piece is slidably connected to the limiting plate.

[0007] Preferably, mounting mechanisms are provided at both ends of the side plates close to the connecting member, a limiting rod is fixed to one side of the connecting member close to the mounting mechanism, and a limiting mechanism is provided above the cross piece.

[0008] Preferably, the limiting mechanism comprises a clamping plate, a supporting spring, a sliding rod and a sliding groove, and a sliding groove is provided above the cross bar.

[0009] Preferably, a slide rod is fixed inside the slide groove, a clamping plate and a support spring are sleeved on the outer side of the slide rod, and the clamping plate and the slide rod are slidably sleeved.

[0010] Preferably, the installation mechanism comprises a bayonet, a rotating shaft, a return spring and a stop rod, and the two ends of the side plate close to the connecting piece are movably sleeved with bayonet pins through the rotating shaft.

[0011] Preferably, a blocking rod is slidably sleeved in a built-in groove of the bayonet close to the bayonet, and a return spring is provided on one side of the blocking rod, and the return spring is located in the built-in groove of the bayonet.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. An installation mechanism is provided. When installing the cover plate on the side plate of the cable tray, the cover plate can be covered on the side plate first, and then the protrusion of the connecting piece is aligned with the notch of the side plate, and the U-shaped opening of the connecting piece is aligned with the limit plate. Then the connecting piece is slid from left to right or from right to left into the two ends of the side plate and the cover plate. After sliding to the position of the bayonet, the bayonet is rotated by the rotating shaft, and the baffle rod is pulled to squeeze the reset spring at the same time, so that the bayonet of the bayonet is stuck on the limit rod on one side of the connecting piece, and then the baffle rod is released to make the reset spring rebound and drive the baffle rod to press against one side of the limit rod to block the bayonet. The setting of the connecting piece and the installation mechanism can improve the connection safety between the cover plate and the side plate, and at the same time facilitate the installation and disassembly of the lightning protection cable tray, thereby improving the convenience of the lightning protection cable tray.

[0014] 2. A limiting mechanism is set up. When installing the cable, the cable can be placed on the inner side of the clamping plate, so that the supporting spring rebounds to generate thrust and pushes the clamping plate to slide to one side on the slide rod in the slide groove, so that the clamping plate is against both sides of the cable. The support of the supporting spring makes the shaking or deviated cable return to its original position, thereby improving the stability of the cable installation and the practicality of the lightning protection cable tray.
