The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized. For cable trays installed in the open air outside the building, if they are near the seaside or in a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact resistance. The tray type cable tray is the most widely used in petroleum, chemical industry, light industry, telecommunications and other fields. It has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation. It is suitable for the installation of power cables and the laying of control cables.

[0006] (2) The prior art patents cannot provide shock absorption when in use. When the bridge frame shakes, the parts inside the bridge frame and the cables will collide and rub, causing damage to the cables and reducing the life of the bridge frame. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a tray-type bridge frame for improving the efficiency of cable laying, which can not only quickly lay cables but also provide shock absorption.

[0010] Furthermore, the locking device includes a latch, the latch is movably connected to a fixed base, a pull ring is provided at the front end of the latch, a limiting ring is provided on the surface of the latch, and a first spring is sleeved on the surface of the latch.

[0011] Furthermore, the fixing device comprises a lifting block, the lifting block is internally threaded with a screw rod, the bottom end of the screw rod is rotatably connected to a fixed base, and the upper end of the screw rod is provided with a knob.

[0012] Furthermore, the front and rear ends of the fixed base are internally slidably connected with a limit rod, the bottom end of the limit rod is fixedly connected to the fixed base, the left and right ends of the lifting block are rotatably connected with a pressure plate, and the bottom surface of the pressure plate is provided with three evenly distributed wire grooves, and the wire grooves correspond to the placement grooves in pairs.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] (1) The utility model solves the problem that the existing tray-type cable tray cannot quickly separate and fix the cables by providing a fixing device and a locking device. Multiple cables are placed in different placement grooves respectively, and the knob is rotated to rotate the screw rod, thereby moving the lifting block downward, so that the pressure plate is close to the cable to fix the cable, effectively preventing the cables from being entangled with each other. The first spring can push the pin into the socket to fix the pressure plate to prevent the cable from loosening.

[0016] (2) The utility model solves the problem that the existing tray-type cable tray cannot provide shock absorption by providing a movable suspension rod. When the tray tray moves up and down due to vibration, the suspension rod moves up and down inside the sleeve, the second spring deforms to absorb the vibration, and the friction between the piston and the sleeve absorbs the elastic potential energy of the second spring, thereby reducing the vibration of the tray tray.
