Description

Technical Field

[0001] The utility model relates to the technical field of bridge frames, in particular to a mortise and tenon glass fiber reinforced plastic bridge frame. Background Art

[0002] During the installation of cables, bridges are generally used for support. Existing bridges are divided into trough, tray, ladder, grid and other structures, which are composed of brackets, supports and installation accessories. Most bridges are made of fiberglass, which generally refers to reinforced plastics with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, with glass fiber or its products as reinforcement material, called glass fiber reinforced plastics.

[0003] When installing and using the FRP cable tray, it is sometimes necessary to splice and assemble two cable trays according to actual needs. During this process, workers are required to use connectors and bolts to connect them. The process is cumbersome, time-consuming and labor-intensive, which affects the installation efficiency of workers.

[0004] A fiberglass bridge with convenient connection, publication number CN213151529U, comprises a first fiberglass bridge and a second fiberglass bridge, both sides of the first fiberglass bridge and the second fiberglass bridge are provided with T-shaped grooves, a connecting plate is fixedly installed on one side of the second fiberglass bridge, and T-shaped sliders are fixedly installed on both sides of the connecting plate. In the utility model, the movement of the connecting plate drives the T-shaped slider to move in the T-shaped groove, and the movement of the connecting plate drives the clamping block to move. As the clamping block continues to move, the movable block will be squeezed and the squeezing spring will be compressed. The movable block moves into the movable groove, and the clamping block continues to move and moves to one side of the movable block. At this time, under the elastic force of the squeezing spring, the movable block can be driven to reset and blocked on one side of the clamping block, so that the connecting plate is fixedly connected to the first fiberglass bridge.

[0005] During use of the above-mentioned device, the user is required to insert his fingers into the removal hole, grab the grab hole with his hand and pull it, thereby driving the manual adjustment rod to move. The movement of the manual adjustment rod drives the movable block to move and move it into the movable groove, and then separate the first fiberglass bridge frame from the second fiberglass bridge frame. However, the overall size of the bridge frame is not too large, and the size of the removal hole opened on the bridge frame also has certain limitations. Therefore, there will be inconvenience in the process of inserting the fingers into the removal hole and pulling the grab hole downward, which affects the disassembly and installation efficiency of the bridge frame.
