Description

Technical Field

[0001] The utility model relates to the technical field of bridge frames, in particular to a chain bridge frame. Background Art

[0002] A bridge, also known as a cable tray, is a building structure used to support cables, wires, pipes, etc. It is widely used in electrical installation projects in industrial and civil buildings, especially in large buildings, factories, data centers and other places. The bridge provides good protection and an orderly wiring environment for the cables. The bridge is usually made of metal, such as steel, aluminum alloy, etc., with high load-bearing capacity and good durability.

[0003] Traditional bridges are usually fixed structures, and their shape and size are difficult to change once they are manufactured. This design limits the adaptability of the bridge when facing complex or changing installation environments. At the same time, due to the fixed nature of traditional bridges, the installation process is often more complicated, requiring precise measurement and preset installation positions. Once positioned, it is difficult to adjust. In addition, traditional bridges have poor adaptability to the installation environment, especially when facing irregular building spaces or special layout requirements. It is difficult to achieve quick and effective installation. Therefore, a chain bridge is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a chain bridge to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The cam is fixedly mounted on a support frame, and the cam is secured to a position 400 meters high and is adapted to engage said support frame when said sliding member is engaged with the vehicle.

[0007] Preferably, the size of the elastic block matches the size of the fixing groove.

[0008] Preferably, the number of the fixing bar, the sliding rail and the sliding block is two each.

[0009] Preferably, the number of the fixing blocks and the number of the limiting blocks are four.

[0010] Preferably, the width of the fixing strip is the same as the width of the limiting block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, the structural deformation capacity of the bridge is improved by providing the rotating shaft and the groove, so that the number of bridge units can be increased or decreased according to the needs of the on-site environment, thereby flexibly adapting to different installation spaces and layout requirements. This flexibility is not available in traditional fixed bridges, greatly improving the application range and adaptability of the bridge;

[0013] 2. In the present invention, the fixing strips and fixing blocks are provided to improve the flexibility of the connection portion of the chain bridge, facilitate the installation steps between the chain bridge and the mounting frame, and improve the installation efficiency of the chain bridge;

[0014] 3. In the present invention, the slide rails and sliders are provided so that the bridge can be adjusted according to the actual installation environment, and whether it is a straight line, a turning or a multi-angle layout, it can be easily achieved. BRIEF DESCRIPTION OF THE DRAWINGS
