[0001] This utility model relates to the field of fastener technology, and in particular to an automotive fastener with a multi-effect locking fastening structure. Background Technology

[0002] Fasteners, also known as standard parts in the market, are characterized by a wide variety of specifications, performance and uses, and a high degree of standardization, serialization and generalization. Fasteners are one of the most widely used basic mechanical components, and are frequently used in daily life and industrial production. They are widely used in various types of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies.

[0003] In existing technologies, fasteners are mechanical parts, which are cylindrical threaded parts that are fitted with nuts. Bolts are a type of fastener consisting of a nut and a threaded rod, which need to be fitted with a nut and are used to fasten two parts with through holes.

[0004] In existing technical solutions, two objects are usually fastened by tightening a nut and a screw. However, in actual use, especially in automobile assembly, these bolts often face harsh working environments, such as bumps and vibrations. These environmental factors may cause the bolts to loosen or come loose, thus causing problems during driving. Summary of the Invention

[0005] The purpose of this utility model is to provide a vehicle fastener with a multi-effect locking and fastening structure, which can improve the stability of the connection when the screw and nut are connected and prevent the nut from loosening due to bumps and vibrations, thus achieving a multi-effect locking effect and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle fastener with a multi-effect locking and fastening structure, including a nut, a screw rod fixedly installed at the bottom end of the nut, and a nut slidably connected to the outer wall of the screw rod, a groove is provided on one side of the nut outside the screw rod, and an abutment mechanism is provided inside the groove;

[0007] The abutting mechanism includes a connecting hole, which is located inside the nut corresponding to the position of the screw.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4 A vehicle fastener with a multi-effect locking and fastening structure includes a nut 1, a screw 2 fixedly mounted at the bottom end of the nut 1, a nut 3 slidably connected to the outer wall of the screw 2, a groove 4 formed on one side of the nut 3 outside the screw 2, and an abutment mechanism 5 provided inside the groove 4; the abutment mechanism 5 includes a connecting hole 501, with the connecting hole 501 having a position inside the nut 3 corresponding to the screw 2, a slot 502 formed inside the connecting hole 501, a locking block 503 slidably connected to the inner wall of the slot 502, and a connecting plate 504 fixedly mounted at one end of the locking block 503 extending out of the slot 502. A connecting block 505 is fixedly installed at the end of the connecting plate 504 away from the locking block 503. A threaded post 507 extends from the bottom end of the screw 2. A bearing plate 506 is fixedly installed at the end of the threaded post 507 extending from the screw 2. The locking block 503 forms a sliding structure with the nut 3 through the locking groove 502. The locking block 503 forms a sliding structure with the sliding groove 4. The connecting plate 504 forms a sliding structure with the screw 2 through the locking block 503. The connecting plate 504 and the threaded post 507 are tightly fitted together. The threaded post 507 is threadedly connected to the screw 2. The screw 2 is tightly fitted with the bearing plate 506.

[0027] By adopting the above technical solution, the nut 3 is first connected to the screw 2 by the connecting hole 501 and together with the nut 1 to form a conventional fastener. When the nut 3 slides, the locking block 503, which is engaged by the slot 502, drives the connecting plate 504 to slide along the slide groove 4 of the screw 2, thereby allowing the connecting block 505 to slide inside the screw 2. At the same time, the threaded post 507 passes through the screw 2 and is threaded, thereby resisting the connecting block 505 to limit and prevent loosening, causing the nut 3 to loosen, thus achieving a multi-effect locking effect. The threaded post 507 can be easily turned by the bearing plate 506.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a stabilizing mechanism 6 is provided below the nut 3. The stabilizing mechanism 6 includes a sleeve 601, which is sleeved on the upper part of the outer bearing plate 506 of the screw 2. An abutment plate 602 is fixedly installed on the top of the sleeve 601. The stabilizing mechanism 6 also includes a limiting rod 603, which is fixedly installed on the top of the abutment plate 602. A limiting hole 604 is opened on the inner wall of the nut 3 corresponding to the position of the limiting rod 603. The limiting rod 603 passes through the limiting hole 604 and enters the interior of the nut 3. The nut 3 and the abutment plate 602 are tightly fitted together.

[0029] By adopting the above technical solution, the sleeve 601 fixed by the bearing plate 506 is threadedly connected to the screw 2, which further improves the stability of the connection. At the same time, before the nut 3 is connected to the screw 2, the limiting rod 603 is inserted into the limiting hole 604. Thus, during the connection, the limiting rod 603 limits the limiting hole 604, thereby limiting the nut 3 to prevent loosening and improving the connection stability, achieving a multi-effect locking effect.

[0030] Working principle: The fastener consists of a nut 1, a screw 2, and a nut 3. The nut 3 rotates through the slot 502 and engages with the locking block 503, which slides along the slide groove 4. This causes the connecting block 505 to slide along the inside of the screw 2 via the connecting plate 504, thus avoiding being limited. The threaded post 507 fixed by the bearing plate 506 passes through the screw 2 and is threadedly connected. The contact connecting block 505 provides multiple tightening to prevent loosening. At the same time, before the nut 3 and the screw 2 are connected, the limiting rod 603 fixed by the contact plate 602 passes through the limiting hole 604 of the nut 3. The contact plate 602 is fixed on the bearing plate 506 via the sleeve 601 and is threadedly connected to the screw 2. This further improves the stability of the connection when the screw 2 and the nut 3 are threadedly connected to the object, and prevents the nut 3 from loosening or coming loose when there are bumps or vibrations.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
