Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to an anti-slip structure for bolt heads. Background Technology

[0002] A bolt is a mechanical part, a type of fastener, consisting of a head and a threaded shaft. 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] The following problems exist: Commonly available hex bolts on the market are prone to slippage during tightening or loosening, especially when using tools. If the tool size does not perfectly match the bolt, this slippage will become more frequent. In addition, when the outer surface of the bolt is exposed to specific environmental conditions for a long time, such as a humid environment or an environment containing corrosive substances, resulting in rust or corrosion, the slippage will be more serious when tightening the bolt. This not only affects work efficiency but may also negatively affect the bolt's tightening performance. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A bolt head anti-slip structure includes a bolt head, a bolt rod fixedly connected to the bottom center of the bolt head, a nut threadedly connected to the bottom end of the outer wall of the bolt rod, and multiple sets of sleeve blocks fixedly connected to the outer walls of both the bolt head and the nut, with rubber sleeves fitted onto the outer walls of each sleeve block.

[0007] As a further description of the above technical solution: A hollow rubber ring is fitted onto the top of the outer wall of the screw, and a top ring is fixedly connected to the outer edge of the top of the hollow rubber ring.

[0008] As a further description of the above technical solution: Both ends of the top ring are fixedly connected with insert blocks, and both ends of the screw head are provided with through holes. The outer wall of the insert block is inserted into the bottom end of the inner wall of the hole.

[0009] As a further description of the above technical solution: Each of the outer walls of the sleeve is fixedly connected to a limiting ring, and each of the inner walls of the rubber sleeve is provided with a limiting groove. The outer wall of each limiting ring is sleeved with the inner wall of the limiting groove.

[0010] As a further description of the above technical solution: The nut has an annular groove at its top outer edge, and a rotating ring is rotatably connected to the inner wall of the annular groove.

[0011] As a further description of the above technical solution: A hollow rubber ring is fixedly connected to the top of the swivel ring, and multiple sets of anti-slip protrusions are fixedly connected to the top of the hollow rubber ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting the sleeve block, the friction of the bolt surface tightening structure can be improved, thereby avoiding slippage. By setting the rubber sleeve, the user's fingers can be protected. By setting the connection structure between the limiting ring and the limiting groove, the stability of the rubber sleeve can be improved, thereby preventing the rubber sleeve from falling off.

[0013] (2) After tightening the nut, the top surface of the hollow rubber ring can be pressed tightly against the surface of the part. At this time, the hollow rubber ring will be deformed by the pressure of the part and the nut. At the same time, the expansion force generated by the hollow rubber ring will make the nut more stable, thereby preventing the nut from loosening. After inserting the screw into the part with the through hole, the bottom part of the outer wall of the hollow rubber ring will also be embedded in the through hole of the part. At this time, the hollow rubber ring will be deformed by the pressure. At the same time, the expansion force generated by the hollow rubber ring will make the connection structure between the screw and the part more stable. Attached Figure Description
