Problems solved by technology
[0002] Shield segment pre-embedded groove technology has been widely used in tunnel engineering. The anti-loosening performance is relatively high when the channel components are installed together. Generally, the anti-loosening components need to be completed with multiple accessories. In the production The combination operation during installation is more troublesome, and the cost of cooperation is relatively high. The installation and combination during maintenance during use is also more troublesome. The connection efficiency during combination is relatively low, and the anti-loosening and stability of the matching connection position The performance is also relatively poor. If the matching connection position is loose, there may be serious safety hazards

Embodiment Construction
[0022] Such as Figure 1 to Figure 7 As shown, a safe and convenient anti-loosening and anti-drawing nut combination adopts a new structural design. An anti-loosening nylon safety card is set in the loose fit groove, and the structure is fixed with the forming nut on the top. A combined anti-loosening hole with a diameter smaller than the outer diameter of the fixing combination screw is set at the center of the anti-loosening nylon safety card. When mating the fixed combination screw, the fixed combination screw can be naturally tapped through the combination anti-loosening hole by tightening downwards, so as to ensure that the anti-loosening nylon safety card and the external thread of the fixed combination screw can be tightly wrapped and connected Together, thus ensuring that the main body of the fixed combination screw has a reliable anti-pull and anti-loosening effect, the combination operation is more convenient when the overall installation is coordinated, the cost is ...

The invention relates to the technical field of rail transit railway assemblies, and particularly relates to a safe and convenient anti-loosening and anti-pulling nut combination. According to the technical scheme, the safe and convenient anti-loosening and anti-pulling nut combination comprises an anti-pulling nut main body structure, an integrally-formed anti-loosening anti-pulling main body base is arranged at the lower end of the anti-pulling nut main body structure, at least one of the anti-pulling nut main body structure and the anti-loosening anti-pulling main body base is of a non-cylindrical structure, a cylindrical main body matched connection threaded hole penetrating through the upper end face of a part is formed in the center of the lower end of the anti-pulling nut main body structure, and a cylindrical safety anti-loosening combined groove with the diameter larger than that of the main body matched connection threaded hole is formed in the upper end of the inner cylindrical face of the main body matched connection threaded hole. The safe and convenient anti-loosening and anti-pulling nut combination has the advantages that it is guaranteed that the main body position of a fixed combined screw has reliable anti-pulling and anti-loosening effects, the combined operation during overall installation and matching is more convenient, the use cost is lower, and the overall safety is higher in the later use process.
