Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically an integrated self-locking nut. Background Technology

[0002] Nuts are a widely used type of fastener. However, ordinary nuts can loosen or even fall off during use, especially in applications involving high-frequency or alternating vibrations. To prevent nuts from loosening and reduce safety hazards, various types of nuts with self-locking functions have been developed. One type of self-locking nut uses an annular and compressible washer on the inner side of one end to provide self-locking capability. However, its self-locking capability is limited by the thickness of the washer, and the washer is prone to aging and has poor reusability, making it difficult to meet usage requirements. Utility Model Content

[0003] The purpose of this invention is to provide an integrated self-locking nut, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The integrated self-locking nut includes a nut body, which has an insert end and an outlet end. An annular washer is provided on one side of the insert end of the nut body. The nut body also includes a spring, one end of which is fixedly connected to the washer, and the other end of which is fixedly connected to the insert end of the nut body. Two side wings are symmetrically arranged on the outer surface of the washer. Two sets of slots are symmetrically arranged on the outer surface of the insert end of the nut body. Each set of slots consists of two protrusions fixed on the outer surface of the nut body.

[0005] Preferably, the outer surface of the pad is provided with an anti-slip layer, which is made of rubber.

[0006] Preferably, the thickness of the side wing is less than the thickness of the gasket.

[0007] Preferably, the outer surface of the nut body has two receiving grooves, which are symmetrically arranged, and the side wing can enter the interior of the receiving groove after being bent.

[0008] Preferably, the depth of the receiving groove is greater than the thickness of the side wing.

[0009] The beneficial effects of this utility model are:

[0010] This type of one-piece self-locking nut, by using a spring, can achieve a greater degree of compression and possess greater elastic potential energy compared to traditional washers. At the same time, the spring is more durable and has good reusability. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, an integrated self-locking nut includes a nut body 1, which has an insert end and an outlet end. An annular washer 2 is provided on one side of the insert end of the nut body 1. The nut body 1 also includes a spring 3, one end of which is fixedly connected to the washer 2, and the other end of which is fixedly connected to the insert end of the nut body 1. Two side wings 4 are symmetrically provided on the outer surface of the washer 2. Two sets of slots are symmetrically provided on the outer surface of the insert end of the nut body 1. Each set of slots consists of two protrusions 5 fixed on the outer surface of the nut body 1.

[0017] After production is completed, the self-locking nut is in the following condition: Figure 3 As shown, the spring 3 is in a compressed state with a large amplitude but without affecting its normal rebound. At the same time, the side wing 4 is bent and fastened to the nut body 1, so that the spring 3 is continuously in a compressed state. Meanwhile, the side wing 4 is located between the two protrusions 5 in the same set of slots. When the nut body 1 is turned by a wrench or other tools, the two protrusions 5 can restrict the rotation of the side wing 4, thereby restricting the rotation of the washer 2. This prevents the washer 2 from rotating relative to the nut body 1 when it rotates with the nut body 1, thus avoiding the twisting of the spring 3.

[0018] After the nut body 1 is fixed, the bent side wing 4 is separated from the nut body 1. This can be done using a flathead screwdriver, pliers, or other tools to prevent the side wing 4 from always being engaged with the nut body 1. After the side wing 4 is separated from the nut body 1, due to the lack of restraint from the side wing 4, the elastic potential energy of the spring 3 can cause the internal thread on the nut body 1 to fit tightly with the external thread on the bolt or screw, thereby giving the nut body 1 a certain degree of self-locking capability.

[0019] Furthermore, the outer surface of the gasket 2 is provided with an anti-slip layer 6, which is made of rubber. The anti-slip layer 6 is used to increase the friction between the gasket 2 and the workpiece in order to minimize the rotation of the gasket 2.

[0020] Furthermore, the thickness of the side wing 4 is less than the thickness of the gasket 2. When the side wing 4 is bent, the impact on the gasket 2 can be reduced, and excessive deformation of the part belonging to the gasket 2 at the connection between the side wing 4 and the gasket 2 can be avoided, which would reduce the contact area between the gasket 2 and the workpiece.

[0021] Furthermore, two receiving grooves 7 are provided on the outer surface of the nut body 1. The two receiving grooves 7 are symmetrically arranged. The side wing 4 can be bent into the interior of the receiving groove 7. When part of the side wing 4 is exposed outside the nut body 1, the side wing 4 is prone to hooking with external objects. The receiving groove 7 can prevent the connection between the side wing 4 and the nut body 1 from failing. There is a gap between the side wing 4 and the receiving groove 7 so that the nut can be folded out from the receiving groove 7.

[0022] Furthermore, the depth of the receiving groove 7 is greater than the thickness of the side wing 4, so as to avoid the side wing 4 from hindering the use of tools such as wrenches when tightening the nut body 1.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
