Wedge tail combined type anti-loosening nut

Abstract

The utility model discloses a wedge tail combined type anti-loosening nut which comprises a nut body, a wedge tail is fixedly connected to the circle center of the outer side face of the nut body, and a bent opening is formed in the side, close to the circle center of the nut body, of the wedge tail. According to the wedge tail combined type anti-loosening nut, through the design of the wedge tail, when the nut is tightened, due to the special structural design, normal acting force far larger than that of a common standard nut can be generated, larger friction force is generated between the nut and a bolt through the enhanced normal acting force, and therefore the anti-loosening and anti-seismic capacity is remarkably improved; and the pressing force on each thread surface is uniformly distributed, so that the nut can better solve the problems of thread wear and shear deformation.

Description

Technical Field

[0001] The utility model relates to the technical field of threaded parts, in particular to a wedge-tail combined anti-loosening nut. Background Art

[0002] A nut is a common fastener, which is usually used with a bolt or a screw to fix or connect two or more parts. The main function of a nut is to provide a threaded hole that matches the thread of the bolt or screw. By rotating the nut, it moves along the thread direction of the bolt or screw, thereby achieving fastening between the two parts. The nut usually has a hole with an internal thread. The size of this hole and the number of threads per inch match the external thread of the bolt or screw. There are many types of nuts, including hexagonal nuts, square nuts, butterfly nuts, ring nuts, etc. These different types of nuts are suitable for different applications.

[0003] The existing nut assembly method is single and has no tightening effect after loading. After long-term and intense use, the nuts of the connected devices will become loose, eventually causing the nuts to slip from the connection, thereby causing accidents. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a wedge-tail combined anti-loosening nut, which solves the problem that the prior nuts do not have an anti-loosening effect.

[0005] To achieve the above purpose, the utility model is implemented through the following technical scheme: a wedge-tail combined anti-loosening nut, including a nut, a wedge tail fixedly connected to the center of the outer side of the nut, and a bending opening is opened on one side of the wedge tail close to the center of the nut.

[0006] Preferably, the widest part of the bottom of the wedge tail is smaller than the inner diameter of the nut, and the height of the wedge tail is consistent with the depth of the inner diameter of the nut.

[0007] Preferably, the bending opening on the surface of the wedge tail includes two upper and lower notches, an angle is formed between the upper notch and the lower notch, and the bending opening is opened on the wedge tail in a random size.

[0008] The wedge tail and the nut are made of the same material.

[0009] The utility model provides a wedge-tail combined anti-loosening nut. It has the following beneficial effects:

[0010] (1) The wedge-tail combined anti-loosening nut, through the design of the wedge-tail, can generate a normal force much greater than that of an ordinary standard nut when the nut is tightened due to its special structural design. This enhanced normal force generates a greater friction between the nut and the bolt, thereby significantly improving the anti-loosening and anti-vibration capabilities, and making the clamping force on each thread surface evenly distributed. Therefore, the nut can better solve the problems of thread wear and shear deformation.

[0011] (2) The wedge-tail combined anti-loosening nut has a locking force that does not decrease even after repeated tightening and disassembly, and can maintain the original locking effect. In applications that require frequent disassembly and reassembly, the anti-loosening nut can continue to provide a stable locking force. By preventing the nut from loosening, it can reduce failures and damage caused by loosening, which is of great significance for ensuring the normal operation of the equipment, extending its service life, and improving safety.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 The present practical embodiment provides a technical solution: a wedge-tail combined anti-loosening nut, comprising a nut, a wedge tail fixedly connected to the center of the outer side surface of the nut, a bending opening formed on one side of the wedge tail close to the center of the nut, the widest part of the bottom of the wedge tail is smaller than the inner diameter of the nut, and the height of the wedge tail is consistent with the depth of the inner diameter of the nut, the bending opening on the surface of the wedge tail comprises two upper and lower notches, an angle is formed between the upper notch and the lower notch, the bending opening is randomly sized and is formed on the wedge tail, and the wedge tail and the nut are made of the same material.

[0017] The present embodiment includes but is not limited to two nuts, and additional nuts can be added as required, and the two surfaces of the wedge tail can always be kept facing the new nut.

[0018] When in use, the anti-loosening nut is characterized in that a wedge tail 2 is provided at the rear end face of the nut 1. When another nut 1 needs to be installed after being installed and tightened, the friction force will gradually increase due to the gradual increase in the slope of the wedge tail 2 when the second nut 1 is installed and contacts with the wedge tail 2, thereby achieving the purpose of locking the anti-loosening nut 1.
