Description

[Technical field]

[0001] The utility model relates to the technical field of nuts, in particular to the technical field of anti-loosening nuts. [Background technology]

[0002] A nut is a mechanical part that is usually used in conjunction with threaded fastening. Its shape is usually hexagonal, square, round, etc., and it has a threaded structure inside to facilitate use with bolts, etc. In the field of mechanical manufacturing, nuts are a common fastener, usually used to connect two or more objects. In addition, nuts also play a very important role in the fields of automobile manufacturing, construction engineering and shipbuilding. In automobile manufacturing, nuts are usually used to connect wheels to car axles. In construction engineering, nuts can be used to connect various structural parts, such as steel structures, prefabricated components, etc.; in shipbuilding, nuts are usually used to connect various hulls, cabins, etc.

[0003] At present, traditional nuts are generally prone to loosening after being tightened, which affects the normal operation of the equipment and requires frequent repeated tightening operations, thereby increasing labor intensity.

[0004] In order to solve the problems raised in the background technology, for example, publication number CN202811784U discloses an anti-loosening nut, the outer edge of which is arranged with anti-skid bosses, the anti-skid bosses are evenly arranged along the outer circumferential direction of the nut, and the anti-skid bosses are designed in a fan-shaped structure. During operation, the wrench can be used to quickly and effectively tighten the nut to prevent the nut from loosening. The structure is reasonably designed, easy to use and labor-saving, and the locking effect is good, which effectively reduces the labor intensity and improves the operation stability of the equipment. However, the structure still has the following shortcomings:

[0005] Since the nut structure is relatively simple and only the anti-slip boss is used to prevent the nut from loosening, when the frequency amplitude of the vibration during the operation of the machine reaches a certain level, the nut will loosen again, resulting in an unsatisfactory anti-loosening effect. [Utility Model Content]

[0006] The purpose of the utility model is to solve the problems in the prior art and to provide an anti-loosening nut, which can lock the nut body through an anti-loosening limit cylinder and further fix the nut body using an anti-loosening component, thereby preventing the nut from loosening easily.

[0007] To achieve the above-mentioned purpose, the utility model proposes an anti-loosening nut, comprising a screw body, a nut body, an anti-loosening limit cylinder, a locking assembly, a groove, and an anti-loosening assembly, wherein the nut body is threadedly installed on the screw body, and an anti-loosening limit cylinder is assembled above the nut body, the anti-loosening limit cylinder is threadedly installed on the screw body, the nut body and the anti-loosening limit cylinder are installed between the locking assembly, and the inner side wall of the anti-loosening limit cylinder is vertically opened with a plurality of long grooves, each of the grooves is equipped with an anti-loosening assembly, and the anti-loosening assembly is used to prevent the nut body from loosening.

[0008] Preferably, the locking assembly includes a threaded hole, a threaded column, and a rotating head. The threaded hole is symmetrically arranged above the nut body. One end of the threaded column passes through an anti-loosening limit cylinder and is tightened and installed with the threaded hole. The other end of the threaded column is provided with a rotating head.

[0009] Preferably, there are four grooves, which are all distributed in an annular manner on the inner side wall of the anti-loosening limit cylinder, and the four grooves correspond to each other.

[0010] Preferably, the anti-loosening assembly includes a limiting column, a locking block, and an installation head, one end of the limiting column passes through the side wall of the anti-loosening limiting cylinder and is connected to the locking block, and the other end of the limiting column is provided with a installation head.

[0011] Preferably, the locking block is in a strip-shaped structure, the locking block is located in the groove, and the size of the locking block is the same as that of the groove.

[0012] Preferably, an outer side wall of the mounting head is provided with a mounting groove, and the mounting groove is in a square structure.

[0013] Beneficial effects of the utility model:

[0014] The utility model can lock and fix the nut body through the coordinated use of the anti-loosening limit cylinder, the locking component and the anti-loosening component. When the nut body is threadedly installed on the screw body, the anti-loosening limit cylinder is screwed into the screw body, and then one end of the threaded column passes through the anti-loosening limit cylinder and is inserted into the threaded hole on the nut body. The rotating head is rotated to lock and fix the anti-loosening limit cylinder and the nut body. Subsequently, a professional tool is used to insert the anti-loosening limit cylinder into the installation groove, and the installation head is rotated. The installation head drives the limit column to rotate, and the limit column drives the locking block to move forward until the locking block is fitted and fixed with the outer wall of the screw body, thereby completing the locking. The anti-loosening limit cylinder can be locked on the screw body through the anti-loosening component, so that the anti-loosening limit cylinder and the nut body cannot rotate by themselves, thereby improving the anti-loosening effect, thereby greatly improving the overall stability, being firm and not easy to loosen, and solving the problem that the nut is easy to loosen.
