[0002] With the rapid development of modern industry and informatization, the use of various types of cables is increasing. Whether in factories, commercial buildings, rail transit or data centers, a large number of cables are needed to transmit power, signals and data. In order to ensure the safe and orderly laying of cables and facilitate maintenance and management, the demand for cable trays and their installation bracket devices is also increasing.

[0003] Existing technologies include a utility model with publication number CN212626930U, which discloses a bracket for installing a cable tray. The patent adopts a cable tray body, a sealing cover is clamped on the cable tray body, and a sealing strip matching the cable tray body is fixedly connected to the bottom end of the sealing cover. Mounting frames are provided on both sides of the cable tray body, and a pair of supporting plates are provided on the lower side of the sealing cover. The two ends of the supporting plates are respectively fitted with two mounting frames, and stud bolts are connected between the supporting plates and the mounting frames. A plurality of through holes evenly distributed and matching the stud bolts are drilled on the supporting plates.

Both ends of the mounting seat are plugged with The threaded rod has an end which is rotatably connected to the mounting plate at one end of the threaded rod away from the mounting plate, and a locking screw is threadedly connected between the mounting plate and the mounting frame, which can make it easy to clamp and fix bridges of different sizes, and easy to ensure the sealing between the sealing cover and the bridge frame body, thereby solving the problem that the current bridge frame bracket cannot fix the bridge frame well, and the cover plate on the bridge frame is easily loosened due to the shaking of the bracket, thereby affecting the sealing between the bridge frame and the cover plate, allowing external rainwater and other debris to enter the bridge frame, thereby affecting the operation of the cables in the bridge frame, and when the bridge is repaired, the cover plate needs to be frequently disassembled during inspection, which can easily cause the bolts used to fix the cover plate to be damaged and fail, and the cover plate cannot be effectively fixed.

[0004] In the process of installing cable bridges and cover plates in daily life, the existing cable bridges and cover plates are fixed in the form of bolts when they are connected. Tools need to be used to perform tedious bolt tightening operations during installation. The process of tightening the bolts one by one is rather tedious, which not only consumes time and manpower, but also may lead to low installation efficiency when the number of installations is large. At the same time, when maintenance or inspection is required inside the bridge, it is also troublesome to remove the bolts. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that bolts are used for fixing, and tools are needed to perform cumbersome bolt tightening operations when the bolts are installed.

[0007] Preferably, the number of the square grooves is two, and the two square grooves are arranged symmetrically with respect to the U-shaped frame.

[0008] Preferably, a circular hole is opened on the surface of the slider, and the slider is slidably connected to the inner wall of the circular hole with a pin. The slider is arranged inside the square groove. There are two sliders, and the two sliders are arranged symmetrically about the U-shaped frame.

[0009] Preferably, the linkage block contacts the inner wall of the U-shaped frame, a mounting hole is provided on the surface of the linkage block, the linkage block is fixedly connected to the surface of the slider, and the inner wall of the linkage block contacts the protrusion.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, by arranging a clamping device, when the bridge frame body and the sealing cover need to be installed, there is no need to use tools to perform tedious bolt tightening operations. The operator only needs to pinch the operating block with one hand and pinch it inward. Under the cooperation of the operating block, the convex block causes the limit spring to be stressed. The limit spring is squeezed and deformed under the force. The deformation then drives the latch, which moves away from the limit hole and slides into the linkage block. Then, while keeping pinching, the latch is driven to slide toward one end of the linkage block under the cooperation of the slider and the square groove. At the same time, the limit pin slides in the slide groove. After sliding out of the limit hole, there is no need to pinch the operating block. When the linkage block moves to the limit hole at the other end, the cooperation of the limit pin and the slide groove drives the connecting arm to slide out of the linkage block, and the linkage plate Cooperate with the fixed block. When it is completely moved, the limit spring loses its constraint, and then drives the pin to be inserted into the limit hole to limit the position of the linkage block. The connecting arm rotates into an inclination angle under the cooperation of the limit pin and the limit block, and slowly approaches the sealing cover, so that the sealing cover and the bridge body are firmly fitted together, and the installation operation is completed. When the bridge body needs to be repaired or inspected, repeat the reverse operation. By setting the clamping device, when the cable bridge and the sealing cover need to be fixed and installed, the fixed installation can be completed with easy operation, which can effectively prevent the occurrence of loosening and displacement between the bridge body and the sealing cover, ensure that the bridge and the bridge cover are always closely connected, and improve the stability of the entire system.
