Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to an anti-loosening bolt with a locking structure. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is fitted with a nut. It is a type of fastener consisting of a head and a threaded shank. It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection.

[0003] Bolts are widely used in our machinery production process. However, existing bolts often loosen or even fall off when the machinery experiences significant vibrations, affecting the production process. Therefore, there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-loosening bolt with a locking structure. Its advantages include providing excellent fixing, preventing loosening caused by external forces rotating the rotating plate and thus the threaded post, thereby improving the bolt's stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A locking bolt with a locking structure includes a rotating plate, a threaded post at the bottom of the rotating plate, a washer fitted on the outer wall of the threaded post below the rotating plate, and a nut fitted on the end of the threaded post away from the rotating plate. The threaded post is characterized in that a shrinkage groove is formed at the middle of the top of the threaded post, and a connecting post is fixed to the inner wall of the shrinkage groove by a return spring. The top of the connecting post is connected to the rotating plate.

[0007] The bottom of the rotating plate is provided with a groove, the top of the threaded column can slide in the groove, and both sides of the top of the threaded column are provided with embedding grooves. Both sides of the inner wall of the top of the groove are provided with embedding blocks, and the embedding blocks are adapted to the embedding grooves.

[0008] The above technical solution works as follows: When using the bolt, align the threaded post with the threaded holes of the two objects to be fixed, align the screwdriver with the rotating plate, and then press down. Upon pressing, the insert block enters the insert groove. Rotating the screwdriver causes the rotating plate to rotate, which in turn causes the threaded post to rotate, moving it between the two objects. Once the threaded post has passed through both objects, tighten the nut to secure it. This provides a good fixing effect and prevents loosening caused by external force rotating the plate and thus the threaded post, improving the stability of the bolt.

[0009] The present invention is further configured such that a limiting groove is formed on the inner wall of the shrinkage groove, and the connecting column can slide within the limiting groove.

[0010] The above technical solution allows for the setting of a limiting groove, which facilitates the limiting of the connecting column and prevents the connecting column from detaching from the shrinkage groove.

[0011] The present invention is further configured such that the bottom end of the threaded column has a frustum-shaped structure.

[0012] The above technical solution, with its frustum-shaped bottom, allows for a narrower bottom on the threaded post, improving the ease with which the post can be inserted between two objects.

[0013] The present invention is further configured such that a limiting hole is provided on one side of the outer wall of the nut, and a fixing pin is inserted into the inner wall of the limiting hole; a fixing groove is provided on the outer wall of the threaded column, and the fixing pin can enter into the fixing groove.

[0014] The above technical solution allows for the following: after the threaded post connects two objects, inserting the fixing pin into the fixing groove will limit the threaded post and prevent it from rotating.

[0015] The present invention is further configured such that the corner of the fixing pin near the fixing groove has an arc-shaped structure.

[0016] The above technical solution, with its arc-shaped structure at one end corner, makes the end of the fixing pin narrower, improving the ease with which the fixing pin can enter the fixing groove.

[0017] The present invention is further configured such that an annular mounting groove is provided on the top of the gasket, and an elastic pad is provided in the annular mounting groove.

[0018] The above technical solutions, including the use of elastic pads, can improve the elasticity of the gaskets and enhance the tightness of the bolt connections.

[0019] The present invention is further provided that the top of the rotating plate is provided with a twisting groove, and an anti-wear layer is provided in the twisting groove.

[0020] Through the above technical solutions, the anti-wear layer can reduce the friction between the screwdriver and the screw groove, thus preventing stripping of the screw in the screw groove.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This anti-loosening bolt with a locking structure is used by aligning the threaded post with the threaded holes of the two objects to be fixed, aligning the screwdriver with the rotating plate, and then pressing down. When pressing, the insert block enters the insert groove. Rotating the screwdriver causes the rotating plate to rotate, which in turn causes the threaded post to rotate and enter between the two objects. When the threaded post passes through the two objects, tighten the nut to fix it in place. This provides a good fixing effect and prevents the bolt from loosening due to external force causing the rotating plate to rotate and the threaded post to rotate, thus improving the stability of the bolt.

[0023] 2. This anti-loosening bolt with a locking structure features a limiting groove that easily limits the connecting post, preventing it from detaching from the contraction groove. The frustum-shaped bottom design allows for a narrower base on the threaded post, improving the ease of insertion between two objects.

[0024] 3. This anti-loosening bolt with a locking structure can limit the threaded post by inserting the fixing pin into the fixing groove after the threaded post connects two objects, thus preventing the threaded post from rotating. The arc-shaped design at one end corner makes the end of the fixing pin narrower, improving the ease with which the fixing pin can enter the fixing groove. Attached Figure Description

[0033] The bottom of the rotating plate 1 is provided with a groove 8, the top of the threaded column 2 can slide in the groove 8, both sides of the top of the threaded column 2 are provided with an embedding groove 9, and both sides of the inner wall of the top of the groove 8 are provided with an embedding block 10, which is adapted to the embedding groove 9.

[0034] In this embodiment, a limiting groove 11 is provided on the inner wall of the shrinkage groove 5, and the connecting column 7 can slide in the limiting groove 11. The limiting groove 11 can conveniently limit the connecting column 7 and prevent the connecting column 7 from detaching from the shrinkage groove 5.

[0035] The bottom of the threaded post 2 has a frustum-shaped structure. The frustum-shaped structure of the bottom of the threaded post 2 makes the bottom of the threaded post 2 narrower, which improves the convenience of inserting the threaded post 2 between two objects.

[0036] Furthermore, a limiting hole is provided on one side of the outer wall of the nut 4, and a fixing pin 12 is inserted into the inner wall of the limiting hole. A fixing groove 13 is provided on the outer wall of the threaded post 2, and the fixing pin 12 can enter the fixing groove 13. When the threaded post 2 connects two objects, the fixing pin 12 is inserted into the fixing groove 13 to limit the threaded post 2 and prevent the threaded post 2 from rotating. The corner of the fixing pin 12 near the fixing groove 13 is arc-shaped. The arc-shaped corner of the fixing pin 12 makes the end of the fixing pin 12 narrower, which improves the convenience of the fixing pin 12 entering the fixing groove 13.

[0037] It is worth mentioning that the top of the gasket 3 is provided with an annular mounting groove, and an elastic pad 14 is provided in the annular mounting groove. The elastic pad 14 can improve the elasticity of the gasket 3 and improve the tightness of the bolt connection.

[0038] Working principle: When in use, align the threaded post 2 with the threaded holes of the two objects to be fixed, align the screwdriver with the rotating plate 1, and then press down. When pressing, the insert block 10 enters the insert groove 9. Rotate the screwdriver, and the screwdriver rotation will drive the rotating plate 1 to rotate. The rotating plate 1 rotates and the threaded post 2 rotates and enters between the two objects. When the threaded post 2 passes through the two objects, tighten the nut 4 to fix it. This achieves a good fixing effect and avoids the situation where external force causes the rotating plate 1 to rotate and drive the threaded post 2 to rotate, which may cause loosening. This improves the stability of the bolt.
