Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, and more specifically, to a shock-resistant and anti-loosening nut. Background Technology
[0002] Traditional nuts are prone to loosening after installation if the external environment is subject to prolonged vibration, resulting in poor overall performance. Therefore, this invention proposes a shock-resistant and anti-loosening nut. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to an anti-vibration and anti-loosening nut, which includes a nut body. One end of the nut body is coaxially provided with a neck ring. A first retaining ring and a second retaining ring that rotate relative to each other are fitted on the neck ring. The end face of the first retaining ring facing the second retaining ring is provided with a plurality of first spherical protrusions. The end face of the second retaining ring facing the first retaining ring is provided with second spherical protrusions that match the first spherical protrusions one by one. The side of the first retaining ring has a first extension portion, and the first extension portion is provided with a first post extending along the axial direction of the first retaining ring. The side of the second retaining ring has a second extension portion, and the second extension portion is provided with a second post extending along the axial direction of the second retaining ring. The nut also includes an elastic ring fitted on the first post and the second post.
[0005] The present invention is further configured such that: the first extension is provided with a clearance notch for the second column to slide into.
[0006] The present invention is further configured such that: the sides of the first column and the second column are respectively provided with positioning grooves for the elastic ring portion to be embedded.
[0007] The present invention is further configured such that the included angle between two adjacent first spherical protrusions is equal, the included angle between two adjacent second spherical protrusions is equal, and each second spherical protrusion is attached to the first spherical protrusion that matches it.
[0008] The present invention is further configured such that: the first extension portion is integral with the first retaining ring; and the second extension portion is integral with the second retaining ring.
[0009] In summary, the present invention has the following beneficial effects: The anti-vibration and anti-loosening nut involved in the present invention, through the continuous tension provided by the elastic ring, causes the two rods to continuously move closer together, causing the first retaining ring to rotate relative to the second retaining ring. Combined with the mutually abutting first and second spherical protrusions, the distance between the first and second retaining rings is increased, thereby achieving the effect of filling the gap between the nut and the connected surface. It has a good anti-loosening effect, is firmly tightened, has perfect overall function, and is highly practical. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0016] Example 1
[0017] See Figures 1 to 4 As shown, the anti-vibration and anti-loosening nut involved in this embodiment includes a nut body 1. A neck ring 2 is coaxially arranged at one end of the nut body 1. A first retaining ring 3 and a second retaining ring 4 that rotate relative to each other are fitted on the neck ring 2. A plurality of first spherical protrusions 5 are arranged around the end face of the first retaining ring 3 facing the second retaining ring. A second spherical protrusion 6 that matches the first spherical protrusions is provided on the end face of the second retaining ring facing the first retaining ring. The side of the first retaining ring 3 has a first extension 7. A first column 8 extending along the axial direction of the first retaining ring is provided on the first extension 7. The side of the second retaining ring 4 has a second extension 9. A second column 10 extending along the axial direction of the second retaining ring is provided on the second extension 9. It also includes an elastic ring 11 fitted on the first column and the second column.
[0018] Furthermore, the included angle between two adjacent first spherical protrusions 5 is equal, the included angle between two adjacent second spherical protrusions 6 is equal, and each second spherical protrusion 6 is attached to the first spherical protrusion 5 that matches it.
[0019] Furthermore, the first extension 7 is integrated with the first retaining ring 3; the second extension 9 is integrated with the second retaining ring 4.
[0020] In this embodiment, the tension provided by the elastic ring 11 causes the first rod 8 and the second rod 10 to move closer together, causing the first retaining ring 3 to rotate relative to the second retaining ring 4. During this process, the first spherical protrusion 5 and the second spherical protrusion 6 come into contact and overlap, increasing the distance between the first retaining ring 3 and the second retaining ring 4 to fill the gap between the nut and the connected surface, thus achieving the anti-loosening effect.
[0021] The neck ring 2 is used for pre-positioning the first retaining ring 3 and the second retaining ring 4. The first retaining ring 3 and the second retaining ring 4 can also move axially relative to the neck ring 2.
[0022] Example 2
[0023] See Figures 1 to 4 As shown, the anti-vibration and anti-loosening nut involved in this embodiment is further configured, based on embodiment 1, with the first extension 7 having an avoidance notch 12 for the second column to slide into.
[0024] In this embodiment, the clearance gap 12 is provided to allow the second column 10 to move toward the first column 8.
[0025] Example 3
[0026] See Figures 1 to 4 As shown, the anti-vibration and anti-loosening nut involved in this embodiment is further configured, based on embodiment 1, with the first column 8 and the second column 10 respectively provided with positioning grooves (not shown) for the elastic ring portion to be embedded in.
[0027] In this embodiment, the positioning groove is used for the installation and positioning of the elastic ring 11.
[0028] The anti-loosening nut of this utility model uses the continuous tension provided by the elastic ring to make the two rods move closer together, causing the first retaining ring to rotate relative to the second retaining ring. With the mutual contact of the first and second spherical protrusions, the distance between the first and second retaining rings is increased, thereby filling the gap between the nut and the connected surface. It has a good anti-loosening effect, is firmly tightened, has a complete overall function, and is highly practical.
