Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a self-locking bolt fastener. Background Technique

[0002] A fastener is a kind of part known as a standard part. Its manufacturing process is simply to fasten and connect two or more parts or components together to form a whole. Since it often uses mechanical connection, the produced parts not only have a wide variety of specifications, but also have very different performances and uses. Now the fasteners in the market have been standardized and serialized, so it can be said that its generalization degree is very high. Now fasteners have become one of the most widely used mechanical basic parts, and the demand in the market is very large.

[0003] At present, most of the bolt fasteners on the market are usually used for fastening on vibrating machinery. Because the bolt fasteners do not have a self-locking structure, they will fall off under continuous vibration, and serious production accidents will occur in severe cases, affecting the production work efficiency. For this reason, we propose a self-locking bolt fastener. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self-locking bolt fastener to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A self-locking bolt fastener, including a bolt and a washer. The washer is movably sleeved on the surface of the bolt. A bonding layer is fixedly connected to the outer side of the bottom of the washer. A release paper layer is arranged at the bottom of the bonding layer. A ring plate is fixedly connected to the top of the washer. The bolt is located inside the ring plate. A plurality of limiting grooves are equidistantly arranged around the inner wall of the ring plate. A limiting block that can move left and right is clamped inside the limiting groove. An internal hexagonal groove is opened in the middle of the top of the bolt.

[0006] Further, two moving grooves are symmetrically opened at the top of the bolt, and the left and right sides of the inner wall of the moving groove are fixedly connected by a connecting column.

[0007] Further, one side of the limiting block away from the limiting groove penetrates through the limiting groove and extends to the outside of the limiting groove and is fixedly connected with a moving plate. The bottom of the moving plate penetrates through the moving groove and extends into the moving groove.

[0008] Further, the moving plate is movably connected with the moving groove, and the moving plate is slidably sleeved on the connecting column.

[0009] Further, a limiting spring is sleeved on the other side of the surface of the connecting column for providing a supporting force to the moving plate, and the top of the bolt is fixedly connected with two symmetrically arranged columns.

[0010] Further, a magic tape hook surface is fixedly sleeved on the surface of the column, and a magic tape loop surface is fixedly connected above the side of the moving plate away from the limiting block.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the mutual cooperation of the bolt, washer, adhesive layer, release paper layer, annular plate, limiting groove, limiting block, moving groove, connecting column, moving plate, limiting spring, column, magic tape hook surface, magic tape loop surface, and internal hexagonal groove, the present utility model solves the problem that most bolt fasteners on the market are usually used for fastening on vibrating machines. Because the bolt fasteners do not have a self-locking structure, they will fall off under continuous vibration, and serious production accidents will occur, affecting the production work efficiency.

[0023] Please refer to Figure 1-6 , a self-locking bolt fastener, including a bolt 1 and a washer 2. The washer 2 is movably sleeved on the surface of the bolt 1. A bonding layer 3 is fixedly connected to the outer side of the bottom of the washer 2. A release paper layer 4 is arranged at the bottom of the bonding layer 3. A circular plate 5 is fixedly connected to the top of the washer 2. The bolt 1 is located inside the circular plate 5. A plurality of limiting grooves 6 are equidistantly arranged around the inner wall of the circular plate 5. A limiting block 7 that can move left and right is clamped inside the limiting groove 6. An internal hexagonal groove 15 is opened in the middle of the top of the bolt 1.

[0024] Specifically, two moving grooves 8 are symmetrically opened at the top of the bolt 1. A connecting column 9 is fixedly connected between the left and right sides of the inner wall of the moving groove 8.

[0025] During specific implementation, one side of the limit block 7 away from the limit groove 6 penetrates through the limit groove 6 and extends to the outside of the limit groove 6, and is fixedly connected to a moving plate 10. The bottom of the moving plate 10 penetrates through the moving groove 8 and extends into the interior of the moving groove 8.

[0026] Specifically, the moving plate 10 is movably connected to the moving groove 8, and the moving plate 10 is slidably sleeved on the connecting column 9.

[0027] During specific implementation, a limit spring 11 is sleeved on the other side of the surface of the connecting column 9 to provide a supporting force for the moving plate 10. The top of the bolt 1 is fixedly connected to two symmetrically arranged upright columns 12.

[0028] Specifically, a hook surface of a magic tape 13 is fixedly sleeved on the surface of the upright column 12, and a loop surface of a magic tape 14 is fixedly connected to the upper part of the side of the moving plate 10 away from the limit block 7.

[0029] During actual application: When in use, pull the moving plate 10 to the side away from the limit groove 6, thereby driving the limit block 7 to move to the side away from the limit groove 6, and at the same time compress the limit spring 11, so that the limit block 7 disengages from the limit groove 6. Then wind and bond the loop surface of the magic tape 14 and the hook surface of the magic tape 13. Then tear off the release paper layer 4. Then insert the bolt 1 into the threaded hole of the workpiece and rotate it clockwise through an external tool to tighten the bolt 1. During the tightening process of the bolt 1, the washer 2 is bonded to the surface of the workpiece through the adhesive layer 3. Then separate the hook surface of the magic tape 13 and the loop surface of the magic tape 14, and release the loop surface of the magic tape 14. Then, under the elastic force of the limit spring 11, drive the moving plate 10 and the limit block 7 to perform a reset movement, so that the limit block 7 is inserted into the corresponding limit groove 6. Through the above steps, the reverse loosening of the bolt 1 can be prevented, and the self-locking, anti-loosening and anti-vibration of the fastener are realized, greatly improving the practicability of the device.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
