Description

Technical Field

[0001] The utility model relates to the technical field of bent-through components, in particular to a bridge bent-through component. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, grid-type cable trays and other structures. They are composed of brackets, supports and installation accessories. They can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized. For the bridge installed in the open air outside the building, if it is 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 strength. At present, in the process of connecting the bridge, it is generally necessary to use a bend member as a transition piece for connection at its turning connection. However, when the current bend member is in use, its two ends are generally connected and fixed to the bridge by multiple bolts. This method requires multiple bolts to be screwed when the bridge is disassembled and assembled, and the operation is relatively cumbersome. Therefore, we propose a bridge bend member to solve the above problems. Utility Model Content

The corresponding moving block 6 is rotatably connected, and a guide pulley assembly 12 is arranged inside the bending member 1. During the use of this bending member, when it is necessary to separate it from the straight-through bridge frame 2, with the cooperation of the handle 9, one of the moving rods 10 can be pushed up by hand. After the moving rod 10 moves up, the corresponding two moving blocks 6 can be driven to move in the opposite direction at the same time under the action of two of the connecting rods 11. When the moving block 6 moves, the spring 8 will be in a compressed state at this time, and the moving block 6 will drive the corresponding clamping block 7 to move out from the inside of the clamping hole 4, so that after the restriction on the fixed block 3 is released, one of the straight-through bridge frames 2 can be removed at this time. During installation, the above operation is repeated. When the straight-through bridge frame 2 and the bending member 1 are plugged in, the moving rod 10 is released. At this time, under the restoring force of the compressed spring 8, the clamping block 7 can be re-clamped in the inside of the clamping hole 4, thereby realizing the connection and fixation of the bending member 1 and the straight-through bridge frame 2.
