AI Technical Summary
Existing nuts are prone to loosening under alternating loads, leading to locking failure. Current solutions, such as installing spring washers, can only prevent loosening in the short term and cannot be effective in the long term.
A novel anti-loosening nut is designed, comprising a nut body, a sliding component, a connecting spring, and a rolling component. Through the cooperation of threads, grooves, and rolling grooves, the stability of the nut and bolt is enhanced.
It effectively prevents nuts from loosening, improves the installation stability of nuts and bolts, and maintains a locking effect over a long period of time.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fastener technology, and relates to a nut, and more particularly to a novel anti-loosening nut. Background Technology
[0002] Bolt and nut assemblies are typically used to fasten one part to another. Due to factors such as alternating loads, nuts often loosen, leading to locking failure. Currently, the solution to this loosening problem is to install washers (especially spring washers) between the nut and the part, which can prevent loosening to some extent. However, as the axial force is applied over time, the anti-loosening effect of the washers gradually weakens or even disappears, so it still cannot fundamentally prevent loosening. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a novel anti-loosening nut that strengthens the overall structure and prevents loosening.
[0004] The purpose of this utility model can be achieved through the following technical solution: A novel anti-loosening nut, comprising a bolt and a nut body, characterized in that the nut body has an opening for the bolt to pass through, and the opening has threads; the upper end of the nut body has a sliding groove; a sliding member that can slide up and down is provided on the nut body and relative to the sliding groove; a connecting spring for the sliding member to slide up and down is provided between the sliding member and the sliding groove; a rolling groove is provided on the nut body, and a rolling member is provided in the rolling groove; a retaining groove that cooperates with the rolling member is provided on the sliding member.
[0005] In the above-mentioned novel anti-loosening nut, one end of the rolling element is connected to the inner wall of the sliding element and is used to prevent loosening of the nut body.
[0006] In the above-mentioned novel anti-loosening nut, one end of the rolling element extends out of the rolling groove and can be inserted into the slot of the sliding element to facilitate the bolt being inserted into the nut body.
[0007] In the aforementioned novel anti-loosening nut, one end of the rolling groove is connected to the slot, and the other end of the rolling groove is connected to the opening of the nut body.
[0008] Compared with the prior art, this new type of anti-loosening nut, when installed, has one end of the rolling element abutting against the inner wall of the sliding element, and the other end of the rolling element abutting against the outer end face of the bolt, which enhances the stability of the nut body installed on the bolt. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the installation cross-sectional structure of this utility model.
[0010] Figure 2 This is a cross-sectional structural diagram of the present invention.
[0011] In the diagram, 1 is the bolt; 2 is the nut body; 3 is the opening; 4 is the thread; 5 is the sliding part; 6 is the connecting spring; 7 is the rolling part; 8 is the rolling groove; and 9 is the slot. Detailed Implementation
[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0013] like Figure 1 As shown, this novel anti-loosening nut includes a bolt 1 and a nut body 2. The nut body 2 has an opening 3 for the bolt 1 to pass through, and the opening 3 has a thread 4. The upper end of the nut body 2 has a sliding groove. A sliding member 5 that can slide up and down is provided on the nut body 2 and relative to the sliding groove. A connecting spring 6 is provided between the sliding member 5 and the sliding groove to allow the sliding member 5 to slide up and down. The nut body 2 has a rolling groove 8, and a rolling member 7 is provided in the rolling groove 8. The sliding member 5 has a retaining groove 9 that cooperates with the rolling member 7.
[0014] To elaborate further, when the nut body 2 is installed on the bolt part 1, the upper end of the nut body 2 abuts against the lower end of the part, and the part presses the sliding part 5 on the nut body 2 downward. The inner wall of the sliding part 5 is connected to the rolling part 7, thereby connecting the other end of the rolling part 7 to the bolt part 1, thus strengthening the stability of the nut body 2 installed on the bolt part 1.
[0015] To elaborate further, when bolt 1, parts, and nut body 2 are installed (e.g.) Figure 1 As shown), one end of the nut rolling element 7 is connected to the inner wall of the sliding element 5 and is used to prevent loosening of the nut body 2.
[0016] To elaborate further, when bolt 1, parts, and nut body 2 are not installed (e.g.) Figure 2 As shown), one end of the rolling element 7 extends out of the rolling groove 8 and can be inserted into the slot 9 of the sliding element 5 to facilitate the bolt 1 to be inserted into the nut body 2.
[0017] In the above-mentioned novel anti-loosening nut, one end of the rolling groove 8 is connected to the slot, and the other end of the rolling groove 8 is connected to the opening 3 of the nut body 2.
[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0019] Although this document frequently uses terms such as bolt 1, nut body 2, opening 3, thread 4, sliding part 5, connecting spring 6, rolling part 7, rolling groove 8, and retaining groove 9, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
