Description

Technical Field

[0001] This utility model relates to the field of automotive parts installation technology, and in particular to a fastener for automotive parts installation with a limiting structure. Background Technology

[0002] Fasteners, also known as standard parts in the market, are a general term for a class of mechanical parts used to fasten two or more parts (or components) together into a whole. They come in a wide variety of types, with different performance and uses. They are highly standardized, serialized, and universal, and are the most widely used basic mechanical parts, especially important in machining and automobile manufacturing.

[0003] In existing technologies, fasteners used for installing automotive parts may experience loosening of nuts due to prolonged vibration during operation. This could lead to detachment of parts, resulting in loose connections and affecting driving safety.

[0004] An existing patent (publication number: CN220396232U) discloses a fastener for installing automotive parts with a limiting structure. By setting a limiting rod and a fixing sleeve, when the nut is screwed onto the bolt rod, the limiting rod can be inserted into the limiting hole to limit and fix the position of the nut. Then, the fixing sleeve is screwed into the bottom of the bolt rod, and finally, the fixing bolt limits and fixes the position of the fixing sleeve. This ensures the stability of the nut on the bolt rod, making it difficult for the nut to loosen when the car vibrates, thus enhancing the stability of automotive parts and the overall safety.

[0005] To address the aforementioned issues, while existing patents offer solutions that can achieve initial fixation through the combination of components such as limiting rods and limiting holes, they require multiple adjustments and installations during actual use, resulting in complex and cumbersome operations. Summary of the Invention

[0006] The purpose of this utility model is to provide a fastener for installing automotive parts with a limiting structure, which can directly limit the nut after the part is tightened to prevent loosening. At the same time, it is convenient and quick to limit the position, avoiding the trouble of multiple adjustments. In addition, the through-groove limits the positioning plate to prevent displacement, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fastener for installing automotive parts with a limiting structure, including a connector, a screw fixedly installed at one end of the connector, a nut sleeved on the outer wall of the screw, and a positioning mechanism provided on the inner wall of the screw;

[0008] The positioning mechanism includes a through groove, which is formed on one side of the nut on the outer wall of the screw, and a positioning plate extends through the through groove. One end of the positioning plate passes through the screw and a limiting block is inserted into it. A placement groove is formed on the outer wall of the limiting block corresponding to the position of the positioning plate. A sliding groove is formed on the inner wall of the screw corresponding to the position of the limiting block. A spring is fixedly installed on the end of the positioning plate that passes through the placement groove.

[0009] Preferably, the positioning plate forms a sliding structure with the screw through the through groove, and the positioning plate forms an elastic structure with the limiting block through the spring.

[0010] Preferably, the outer dimensions of the limiting block and the outer dimensions of the sliding groove are matched, and the limiting block and the screw form a sliding structure through the sliding groove.

[0011] Preferably, a connecting block is fixedly installed at the end of the screw away from the connector, and an adjustment mechanism is provided inside the connecting block.

[0012] Preferably, the adjusting mechanism includes a rotating block, which is rotatably connected inside the connector, and the inner wall of the connector is provided with a rotating hole corresponding to the position of the rotating block.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3A fastener for mounting automotive parts with a limiting structure includes a connector 1, a screw 2 fixedly mounted on one end of the connector 1, a nut 3 sleeved on the outer wall of the screw 2, and a positioning mechanism 4 provided on the inner wall of the screw 2. The positioning mechanism 4 includes a through groove 401, which is formed on one side of the nut 3 on the outer wall of the screw 2. A positioning plate 402 extends through the inside of the through groove 401. One end of the positioning plate 402, which enters the screw 2, is inserted into a limiting block 403. The outer wall of the limiting block 403 has a corresponding position on the positioning plate 402. The mounting groove 404 has a sliding groove 406 on the inner wall of the screw 2 corresponding to the position of the limiting block 403. A spring 405 is fixedly installed at one end of the positioning plate 402 that passes through the mounting groove 404. The positioning plate 402 forms a sliding structure with the screw 2 through the through groove 401. The positioning plate 402 forms an elastic structure with the limiting block 403 through the spring 405. The outer dimensions of the limiting block 403 and the outer dimensions of the sliding groove 406 match. The limiting block 403 forms a sliding structure with the screw 2 through the sliding groove 406.

[0028] By adopting the above technical solution, when the nut 3 is adjusted along the screw 2, it presses the inclined part of the positioning plate 402 when it reaches the position of the slot 401. This presses the spring 405 through the mounting slot 404 into the limiting block 403. When the nut 3 slides past the positioning plate 402, the positioning plate 402 loses pressure and is pushed back by the spring 405. This can resist the nut 3 to limit it and prevent loosening. At the same time, it is convenient and quick to install and avoids the trouble of multiple adjustments.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, a connecting block 5 is fixedly installed at the end of the screw 2 away from the connector 1. An adjustment mechanism 6 is provided inside the connecting block 5. The adjustment mechanism 6 includes a rotating block 601, which is rotatably connected to the inside of the connector 1. A rotating hole 602 is provided on the inner wall of the connector 1 corresponding to the position of the rotating block 601. A connecting groove 603 is provided on the inner wall of the rotating hole 602. A limit plate 604 is fixed on the outer wall of the rotating block 601 corresponding to the position of the connecting groove 603. The adjustment mechanism 6 also includes a through hole 605, which is opened inside the limit block 403. A threaded rod 606 extends out of the through hole 605 and is threadedly connected to the limit block 403. A sliding structure is formed between the limit block 403 and the threaded rod 606.

[0030] By adopting the above technical solution, the rotating block 601 is turned, and the limiting plate 604 rotates inside the connecting groove 603 of the rotating hole 602, avoiding loosening or disengagement. This drives the threaded rod 606 to rotate, allowing the limiting block 403 to slide along the threaded rod 606 through the through hole 605 and adjust its position inside the sliding groove 406. This adjusts the position of the positioning plate 402, improving flexibility and applicability by adjusting according to the thickness of the parts to be clamped.

[0031] Working principle: Connector 1, screw 2, and nut 3 form a conventional fastener. Limiting block 403 is located inside screw 2 via sliding groove 406. Spring 405 elastically pushes positioning plate 402 to slide along placement groove 404, and finally passes through through groove 401. One end of positioning plate 402 is inclined to facilitate compression of spring 405 after nut 3 is tightened, and the other end is flat, thus blocking nut 3 to limit its position and prevent loosening. Connecting block 5 fixed to screw 2 is rotated through rotating hole 602 and connecting groove 603, allowing rotating block 601 to rotate through limiting plate 604. By manually turning rotating block 601, threaded rod 606 rotates. Threaded rod 606 is threadedly connected to limiting block 403 through through hole 605, thereby adjusting the sliding of limiting block 403 along sliding groove 406. The position can be adjusted according to the thickness of the part to achieve a tight fit and prevent loosening.

[0032] 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.
