Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machinery, in particular to a hexagonal flange surface anti-loosening nut. Background Art
[0002] Nuts are usually fastening parts that are screwed together with bolts or screws for tightening. When using ordinary hexagonal nuts and bolts or screws to lock parts, in order to prevent the nuts from loosening, the following methods are usually used: first put a flat washer or spring washer on the bolt, and then tighten the nut on the bolt with a wrench, relying on the flat washer or spring washer to increase the friction between the nut and the matching thread of the bolt or screw, thereby preventing the nut from loosening; double nut anti-loosening, through a left-handed nut and a right-handed nut, tighten and prevent loosening; apply nut anti-loosening liquid to the tightening part of the bolt or screw, and then screw on the nut.
[0003] The application number is CN 211693157 U, which discloses a hexagonal flange anti-loosening nut that is easy to install, including a hexagonal nut body, a flange surface is fixedly provided on one end face of the hexagonal nut body, the flange surface is integrally formed with the hexagonal nut body, a friction surface is provided on the flange surface to increase the friction force between the contact surface, a slot is provided on one side face of the hexagonal nut body, and a fixing hole is provided on the lower end face of the slot; an anti-loosening buckle, the anti-loosening buckle includes a clamping part and a handle, a rotating shaft is fixedly provided on the clamping part, the anti-loosening buckle is separated from the bolt in the forward rotation, and is in conflict with the bolt in the reverse rotation. The rotating shaft of the utility model can be directly installed in the fixing hole through the slot, and the anti-loosening buckle can be fixedly installed in the slot without other auxiliary tools or parts, and it is easy to disassemble; the anti-loosening buckle and the friction surface are provided to prevent the nut from loosening, and double anti-loosening can be effectively prevented even under conditions of frequent vibration.
[0004] However, there is a disadvantage that when the device is in use, a certain amount of friction will be generated on the surface of the bolt, which will cause greater wear to the bolt during use, affecting the service life of the bolt. Therefore, a hexagonal flange surface anti-loosening nut that can reduce wear is needed. Summary of the invention
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model discloses a hexagonal flange anti-loosening nut, comprising a flange ring, a nut is fixedly connected to the top of the flange ring, a circular groove is arranged inside the nut, and an annular block B and an annular block A are slidably connected to the outside of the circular groove, so as to achieve the effect of preventing loosening and reducing wear at the same time.
[0007] Compression springs are evenly arranged on one side of the annular block B and the annular block A, and clamping blocks A and B are fixedly connected on the other side of the compression springs.
[0008] The nut is provided with a thread groove inside, and one side of the flange ring is evenly provided with mounting holes.
[0009] A threaded rod is fixedly connected to one side of the annular block A and the annular block B. The threaded rod passes through the nut and extends to the outside of the nut. The threaded rod and the nut are threadedly connected.
[0010] The circular groove is large enough to accommodate the annular block A, the compression spring and the clamp block A. The clamp block A and the clamp block B are made of rubber, thereby achieving the effect of preventing loosening and reducing wear.
[0011] The utility model has the following beneficial effects:
[0012] The utility model: by rotating the threaded rod 11 through the clamping block and the annular block, the threaded rod drives the annular block B and the annular block A to move inwards, the annular block B and the annular block A drive the compression spring to move inwards, and the compression spring drives the clamping block A and the clamping block B to move inwards, thereby achieving the effect of preventing loosening and reducing wear;
[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
