Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to an air duct bridge frame which is easy to maintain. Background Art

[0002] Duct bridge is a metal structure used to support and fix ducts, cables and other equipment. Its main function is to hang these equipment from the ground or wall to avoid being affected by ground excavation, pressure and other factors.

[0003] Common duct bridges use fixed screw structures for support. In the subsequent maintenance process, the screws need to be removed to remove the bridge together with the fixed ducts and cables on the upper end of the bridge. Therefore, those skilled in the art provide a duct bridge that is easy to maintain to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a duct bridge frame that is easy to maintain, including a frame plate, side frame plates are arranged at the left and right ends of the frame plate, cylinder retractable rods are symmetrically arranged at the upper end of the side frame plate, and the lower end of the cylinder retractable rod is movably connected to the side frame plate through a locking structure arranged on the side frame plate;

[0005] The locking structure includes a turning knob, a turning tooth, a meshing tooth, a linkage tooth, a limiting ring groove, an open ring tooth and a lock mouth. A limiting ring groove is provided in the middle of the lock mouth, and an open ring tooth is arranged in the limiting ring groove. A turning tooth that can rotate freely is arranged in the angle shell at the upper end of the side frame plate. Meshing teeth are symmetrically arranged on the upper side of the turning tooth. A linkage tooth is arranged on the upper side of the meshing tooth. The linkage tooth is meshed with the tooth pattern of the open ring tooth. The turning knob is used to drive the turning tooth. The meshing tooth pattern of the turning tooth is engaged to drive the meshing tooth to rotate. The meshing tooth then meshes with the linkage tooth. At this time, the linkage tooth meshes with the open ring tooth, so that the open ring tooth slides within a limited position in the limiting ring groove, thereby locking and connecting the cylinder retracting rod on the lock mouth, and the side frame plate and the frame plate can be stably hoisted at the lower end of the cylinder retracting rod.

[0006] Preferably, hinge assemblies are symmetrically installed at the front and rear ends of the side frame plate, and a recessed seat plate is formed between the side frame plate and the frame plate through the hinge assembly to support the air duct.

[0007] Preferably, a fixing seat is symmetrically arranged at the front and rear ends of the upper ends of the cylinder retractable rods, and the fixing seat uses fastening bolts to hang the cylinder retractable rods on the top of the wall in the use area.

[0008] Preferably, a knob is fixedly mounted on the middle of the front end of the rotating tooth, and the knob is rotationally limited and arranged on the front end surface of the side frame plate.

[0009] Preferably, the left and right corners on the upper end of the side frame plate are opened and closed with locks.

[0010] Preferably, the lock opening corresponds to the size of the opening of the open ring teeth.

[0011] Technical effects and advantages of the utility model:

[0012] When the utility model is used, the rotating gear is driven to rotate by turning the knob, and the meshing of the rotating gear tooth pattern drives the meshing gear to rotate, and the meshing gear then meshes with the linkage gear. At this time, the linkage gear meshes with the open ring gear, so that the open ring gear slides within the limiting ring groove, and then the opening of the open ring gear corresponds to the lock mouth, so that the side frame plate and the cylinder retracting rod lifting connection are released, and then the side frame plate and the frame plate are bent by the hinge assembly, so that the air duct on the frame plate can be disassembled, thereby ensuring the convenience of subsequent repair and maintenance and reducing the tediousness of disassembly.
