Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The self-locking type fixing member with adjustable length comprises a fixing member shell 1, a fixing member hook 2, asymmetric teeth and a bidirectional pawl 6, wherein a sliding groove 9 is formed in the middle of the upper surface of the fixing member shell 1, a hook passing hole 10 is formed in one side surface of one end of the fixing member shell, and the asymmetric teeth are formed in the fixing member shell along the two sides of a long edge; the fixing member hook 2 passes through the through hole 10 and is arranged below the asymmetric teeth, one end, far away from the hook, of the fixing member hook 2 is connected with an address locking device, and the locking device is meshed with the asymmetric teeth through the bidirectional pawl 6 for self locking. The fixed member hook 2 comprises a hook end 11 and a sliding end 12 which are connected into a whole, the sliding end 12 is arranged below the middle parts of the left rack and the right rack of the asymmetric tooth in a sliding mode, the hook end 11 penetrates through the hook to be connected with the sliding end 12 in the fixed construction shell 1 through a hole 10, a connecting bolt 13 is arranged on one side, far away from the hook end 11, of the sliding end 12, and the locking device is connected with the connecting bolt 13. The locking device comprises a spring 5, a bidirectional pawl 6 and a pressing nut 8, wherein the spring 5 and the bidirectional pawl 6 are sleeved on the connecting bolt 13 from bottom to top at one time, and the pressing nut 8 is connected to the top of the bidirectional pawl 6; the pressing nut 8 passes through the sliding groove 9 to be higher than the upper surface of the fixed member housing 1. The pressing nut 8 is connected with the bidirectional pawl 6 through a flat key. The asymmetric teeth comprise a first rack 3 and a second rack 4 which are symmetrically arranged, and the cross sections of the first rack 3 and the second rack 4 are 7. The bottom ends of the two racks are designed with symmetrical and equal-height retraction spaces, and the tangential planes are in a 7 shape and an inverse 7 shape, so that the bidirectional pawl can be separated from the racks after being pressed down, the bidirectional pawl has the capability of moving back and forth, the two racks are independently designed, the working tooth surfaces of the two racks are positioned on the same plane, and the bidirectional pawl is matched with the specially designed double pawl to play the role of locking in the front-back direction simultaneously.

When the fixing member shell 1 is fixed with the surface or the part of the equipment, the pressing nut 8 is pressed down, the bidirectional pawl 6 is pressed down to the space below the two asymmetric racks, the bidirectional pawl 6 is separated from the first rack 3 and the second rack 4, then the pressing nut 8 is pushed, after the fixing member hook 2 is stretched or shortened to a proper length, the pressing nut 8 is released, the pressing nut 8 rebounds to a position meshed with the first rack 3 and the second rack 4 under the action of the spring 5, and the pressing nut is meshed with the racks to be self-locked, so that the purpose of locking the length of the fixing member hook 2 is achieved.
