Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more particularly to a bolt and nut fastener. Background Technology

[0002] Fasteners are essential basic components in modern industry and are widely used in many fields such as machinery manufacturing, construction, automobiles, aerospace, and electronics.

[0003] Bolts and nuts are fasteners widely used in various fields such as machinery, construction, automobiles, and aerospace. They are indispensable basic components in modern industry and are suitable for a variety of materials and environmental conditions.

[0004] In the prior art, such as the Chinese announcement number CN115126762A, a high-tightness anti-loosening bolt and nut mating assembly includes a connecting bolt, an anti-slip pad, a fastening nut, and a tapered locking member. The lower end of the connecting bolt is fixedly provided with a bolt head, and the upper end of the bolt head is fixedly provided with a locking groove. The upper outer wall of the connecting bolt is fixedly provided with a connecting external thread. The lower end of the anti-slip pad is fixedly provided with a clamping head, and the upper end of the anti-slip pad is fixedly provided with anti-slip texture. The anti-slip pad is fixedly provided with a through hole.

[0005] The aforementioned application is reusable and easy to process through the coordinated operation of multiple components. However, during use, it is equivalent to adding a nut and connecting two nuts. Under vibration, the two connected nuts may rotate together and become loose. Summary of the Invention

[0006] This invention, through the cooperation of a locking block, a movable plate, a rotating shaft, a first sliding rod, and a compression spring, facilitates the user's connection of the connecting disc to the nut body. After connection, it prevents the nut body from rotating, thereby achieving an anti-loosening effect and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bolt and nut fastener, comprising a bolt body, wherein a circular groove is formed inside the bolt body, a column is fixedly connected to the inner wall of the circular groove, a connecting plate is slidably connected to the inner wall of the column, a connecting disc is fixedly connected to the outer wall of the connecting plate, a first sliding rod is fixedly connected to the top of each connecting disc, a rotating shaft is rotatably connected to the shaft end of each first sliding rod, a movable plate is fixedly connected to the outer wall of each rotating shaft, a locking block is fixedly connected to the outer wall of each movable plate, a compression spring is sleeved on the outer wall of the first sliding rod, and a nut body is threadedly connected to the outer wall of the bolt body, and a locking groove is formed on the outer wall of each nut body. Through the above components, the rotation of the nut is prevented, ensuring that the nut body can be stably positioned on the bolt body.

[0008] Preferably, a guide rod is fixedly connected to the inner wall of the column, and the outer wall of the guide rod is slidably connected to the inner wall of the connecting plate. Through the cooperation of the guide rod, the circular groove and the column, an auxiliary function can be indirectly achieved, making it difficult for the nut body to fall off the bolt body.

[0009] Preferably, a second sliding rod is fixedly connected to the top of each connecting disc, and an anti-slip pad is fixedly connected to the shaft end of the second sliding rod. The bottom of the nut body is slidably connected to the top of the anti-slip pad. By setting the second sliding rod and the anti-slip pad, the friction between the connecting disc and the nut body is increased, preventing the nut body from rotating, and indirectly playing an auxiliary role.

[0010] Preferably, a first rubber pad is fixedly connected to the bottom of the bolt body, and a second rubber pad is fixedly connected to the top of the nut body. By setting the first and second rubber pads, friction can be increased when in contact with the surface of the connected parts.

[0011] Preferably, the inner wall of the card slot is slidably connected to the outer wall of the card block, so that the card block can be moved normally into or out of the card slot.

[0012] Preferably, one end of the compression spring is fixedly connected to the outer wall of the connecting disc, and the other end of the compression spring is fixedly connected to the outer wall of the rotating shaft, so that both ends of the compression spring are connected, thus preventing detachment during use.

[0013] Preferably, a set of pull rods is fixedly connected to the outer wall of the card block. The pull rods allow the user to easily pull the connected card blocks so that the two card blocks can be disengaged from the card slot.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, when the nut body is screwed into the bolt body, the user can put the connecting plate into the circular groove and put it on the guide rod and column. Then, through the cooperation of the locking block, the movable plate, the rotating shaft, the first sliding rod and the compression spring, the user can easily connect the connecting disc to the nut body. After connection, the nut body can be prevented from rotating, thereby achieving the effect of preventing loosening.

[0015] 2. In this invention, the cooperation of the second sliding rod and the anti-slip pad increases the friction between the connecting disc and the nut body, indirectly ensuring that the nut body is not easily rotated, thus playing an auxiliary role. The first rubber pad and the second rubber pad can better protect the parts when fastening the object, preventing them from being damaged. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4 This invention provides a technical solution: a bolt and nut fastener, comprising a bolt body 1, a circular groove 6 inside the bolt body 1, a column 7 fixedly connected to the inner wall of the circular groove 6, a connecting plate 9 slidably connected to the inner wall of the column 7, a connecting disc 10 fixedly connected to the outer wall of the connecting plate 9, a first sliding rod 16 fixedly connected to the top of each connecting disc 10, a rotating shaft 15 rotatably connected to the shaft end of each first sliding rod 16, a movable plate 14 fixedly connected to the outer wall of each rotating shaft 15, a locking block 17 fixedly connected to the outer wall of each movable plate 14, a compression spring 18 sleeved on the outer wall of the first sliding rod 16, and a nut body 4 threadedly connected to the outer wall of the bolt body 1, with a locking groove 5 on the outer wall of each nut body 4. Through the above components, rotation of the nut is prevented, ensuring that the nut body 4 can be stably positioned on the bolt body 1.

[0021] like Figure 1 and Figure 2 As shown, a guide rod 8 is fixedly connected to the inner wall of the column 7. The outer wall of the guide rod 8 is slidably connected to the inner wall of the connecting plate 9. Through the cooperation of the guide rod 8, the circular groove 6 and the column 7, an auxiliary function can be indirectly achieved, making it difficult for the nut body 4 to fall off the bolt body 1.

[0022] like Figure 1 and Figure 3 As shown, a second slide rod 11 is fixedly connected to the top of the connecting disc 10, and an anti-slip pad 12 is fixedly connected to the shaft end of the second slide rod 11. The bottom of the nut body 4 is slidably connected to the top of the anti-slip pad 12. By setting the second slide rod 11 and the anti-slip pad 12, the friction between the connecting disc 10 and the nut body 4 is increased, the nut body 4 is prevented from rotating, and it also indirectly plays an auxiliary role.

[0023] like Figure 1 and Figure 2 As shown, a first rubber pad 2 is fixedly connected to the bottom of the bolt body 1, and a second rubber pad 3 is fixedly connected to the top of the nut body 4. By setting the first rubber pad 2 and the second rubber pad 3, friction can be increased when in contact with the surface of the connected parts.

[0024] like Figure 1 and Figure 4 As shown, the inner wall of the card slot 5 is slidably connected to the outer wall of the card block 17, so that the card block 17 can be moved normally into or out of the card slot 5.

[0025] like Figure 1 and Figure 4 As shown, one end of the compression spring 18 is fixedly connected to the outer wall of the connecting disc 10, and the other end of the compression spring 18 is fixedly connected to the outer wall of the rotating shaft 15, so that both ends of the compression spring 18 are connected to avoid detachment during use.

[0026] like Figure 1 and Figure 4 As shown, a set of pull rods 13 are fixedly connected to the outer wall of the card block 17. The pull rods 13 make it easy for the user to pull the connected card blocks 17 so that the two card blocks 17 can be disengaged from the card slot 5.

[0027] The usage and working principle of this device are as follows: First, screw the bolt on the bolt body 1 into the through hole on the workpiece, so that the surface of the first rubber pad 2 is in contact with the workpiece. Then, screw in the nut body 4 to connect with the bolt until the second rubber pad 3 is in contact with the surface of the workpiece. Next, align the connecting plate 9 with the column 7 and guide rod 8 in the circular groove 6. Once aligned, it can be inserted. After insertion, the connecting plate 9 can slide on the column 7 and guide rod 8. When it slides to the appropriate position, the user first adjusts the position of the movable plate 14 through the rotating shaft 15 so that the locking block 17 on the movable plate 14 is in contact with the nut body 4. The corresponding slot 5 on the upper part is oriented accordingly. Then, the corresponding pull rod 13 is pulled, so that the locking block 17 can be moved horizontally under force. When it moves, it drives the rotating shaft 15, the first slide rod 16 and the compression spring 18. When it is pulled to a certain position, it can be released. Then, the locking block 17 can be forcefully inserted into the slot 5 by the elastic force of the compression spring 18 to realize the connection between the connecting disc 10 and the nut body 4. In actual use, through the cooperation of multiple parts, and with the assistance of the second slide rod 11 and the anti-slip pad 12, the nut body 4 is not easy to rotate on the screw, and the disassembly and assembly process is relatively simple, which is convenient for subsequent use.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
