Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a special anti-loosening nut for recreational vehicles. Background Art

[0002] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that all manufacturing machinery must use. It is divided into several types according to the material, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] During the driving process of the RV, bumps or vibrations frequently occur. The existing nuts will become loose due to the impact force generated by the vibrations for a long time, which will have a certain impact on the driving safety of the RV. Therefore, a special anti-loosening nut for RV is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a special anti-loosening nut for RVs, which solves the problems mentioned in the above background technology.

[0005] The utility model is implemented in this way: a special anti-loosening nut for RV is mainly composed of a main nut, a locking nut and a fixing gasket, the locking nut is conical, and the locking nut is arranged inside the main nut, the top end of the fixing gasket is arranged inside the main nut, the top end of the fixing gasket is fitted with the bottom surface of the locking nut, and the main nut is threadedly connected with the locking nut.

[0006] A further technical solution of the utility model is: a first internal thread is provided on the inner side of the main nut, and a first fastening thread is provided on the conical surface of the main nut.

[0007] A further technical solution of the utility model is: a second fastening thread is provided on the conical surface of the locking nut, the second fastening thread is matched with the first fastening thread, and a second internal thread is provided on the inner side of the locking nut.

[0008] A further technical solution of the utility model is that a plurality of equally spaced fixing grooves are arranged on the bottom surface of the locking nut.

[0009] A further technical solution of the utility model is: a fixing ring is provided on the fixing gasket, the fixing ring is placed inside the main nut, and the upper surface of the fixing ring is in contact with the locking nut.

[0010] A further technical solution of the utility model is: a plurality of equally spaced fixed blocks are arranged on the fixed ring, the number of the fixed blocks is equal to the number of the fixed grooves, and the fixed blocks are embedded in the fixed grooves.

[0011] Beneficial effects of the utility model: Compared with traditional nuts, the utility model is composed of a main nut, a locking nut and a fixing washer, wherein the locking nut and the main nut are connected through an inclined thread (i.e., through a first fastening thread inside the main nut and a second fastening thread on the conical surface of the locking nut). When the first internal thread of the main nut is affected by an impact force and is about to loosen, the locking nut connected to the main nut will generate a force in the opposite direction, thereby stopping the rotation of the main nut and preventing it from loosening. At the same time, the fixing washer will be embedded in the inside of the main nut, connecting the main nut and the locking nut at the same time, preventing a gap or looseness between the two, so as to provide a secondary fixing effect, which can greatly improve the stability of the nut.

[0018] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of the present specification are only used to match the contents disclosed in the specification for people familiar with the technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present utility model, should still fall within the scope of the technical contents disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the present specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present utility model. The change or adjustment of the relative relationship, without substantial change of the technical contents, should also be regarded as the scope of the implementation of the present utility model.

[0020] Figure 1-Figure 4 The structural composition of a special anti-loosening nut for RVs is shown, which is mainly composed of a main nut 1, a locking nut 2 and a fixing gasket 3. The locking nut 2 is conical, and the locking nut 2 is arranged inside the main nut 1. The top end of the fixing gasket 3 is arranged inside the main nut 1, and the top end of the fixing gasket 3 is fitted with the bottom surface of the locking nut 2. The main nut 1 and the locking nut 2 are threadedly connected.

[0021] like Figure 1 As shown, a first internal thread 11 is provided on the inner side of the main nut 1 , and a first fastening thread 12 is provided on the conical surface of the main nut 1 .

[0022] A second fastening thread 21 is provided on the conical surface of the locking nut 2 , and the second fastening thread 21 is matched with the first fastening thread 12 . A second internal thread 23 is provided on the inner side of the locking nut 2 .

[0023] The first internal thread 11 on the main nut 1 and the second internal thread 23 on the locking nut 2 have the same thread size, and both are threads connected to the bolt.

[0024] like Figure 4 As shown, a plurality of equally spaced fixing grooves 22 are provided on the bottom surface of the locking nut 2 .

[0025] Meanwhile, a fixing ring 31 is provided on the fixing gasket 3, and the fixing ring 31 is placed inside the main nut 1, and the upper surface of the fixing ring 31 is in contact with the locking nut 2. A plurality of equidistantly distributed fixing blocks 32 are provided on the fixing ring 31, and the number of the fixing blocks 32 is equal to the number of the fixing grooves 22, and the fixing blocks 32 are embedded inside the fixing grooves 22. The locking nut 2 is connected to the fixing ring by the fixing blocks 32 being embedded in the fixing grooves 22.

[0026] The working principle of this RV special anti-loosening nut is as follows:

[0027] In actual work, the locking nut 2 and the main nut 1 are connected through the bevel thread (that is, through the first fastening thread 12 on the inner side of the main nut 1 and the second fastening thread 21 on the conical surface of the locking nut 2). When the first internal thread 11 of the main nut 1 is affected by the impact force and is about to loosen, the locking nut 2 connected to the main nut 1 will generate a force in the opposite direction, thereby stopping the rotation of the main nut 1 and preventing it from loosening. At the same time, the fixing gasket 3 will be embedded in the inside of the main nut 11, connecting the main nut 1 and the locking nut 2 at the same time, preventing a gap or looseness between the two, so as to provide a secondary fixing effect, which can greatly improve the stability of the nut.
