Embodiment Construction

[0048] Hereinafter, the present invention is described in further detail in conjunction with accompanying drawings and specific embodiments.

[0049] like Figure 1-32As shown, bolt anti-loose sleeve, including: anti-loose sleeve 1 is a metal tube of the hollow tube structure, the inner wall of the hollow tube is a circular hollow tube, the outer surface of the hollow tube is a polygonal column; the polygon column is six sides Structure; anti-loose sleeve 1 is open, the other end is connected to the ring panel 11, the surface center region of the loop panel 11 is provided with at least one through hole; wherein the inner passage of the circular circle panel 11 is larger than the bolt 3 screw 31. The outer diameter; the spacer 4 is a ring structure of the through hole, and at least one surface of the gasket 4 is provided with a procedure 41; the first anti-loose teeth 411 and the second anti-loose teeth 412 are arranged in the anti-loose teeth 412 Contrary to the direction of the di...

Abstract

The invention discloses a bolt anti-loosening sleeve. The bolt anti-loosening sleeve is characterized in that an anti-loosening sleeve body (1) is a metal pipe of a hollow pipe structure, the inner wall of the hollow pipe is a round hollow pipe, and the outer surface of the hollow pipe is a polygonal cylinder; the polygonal cylinder is of a hexagonal structure; one end of the anti-loosening sleeve body (1) is open, the other end of the anti-loosening sleeve body (1) is connected with a ring panel (11), and the center area of the surface of the ring panel (11) is provided with at least one through hole; the inner diameter of the through hole in the ring panel (11) is larger than the outer diameter of a screw (31) of a bolt (3); and a gasket (4) is of a circular ring structure with a through hole, and at least one surface of the gasket (4) is provided with anti-loosening teeth (41). Due to downward pressure applied to the head of the bolt or a nut by the anti-loosening sleeve body, the bolt and the nut cannot ascend rotatably in opposite directions, then loosening cannot occur, and the anti-loosening effect is achieved. The bolt and the nut can be repeatedly used.

Description

Technical field [0001] The present invention relates to the locking bolt, the locking sleeve in particular relates to a hot melt connection. Background technique [0002] The conventional locking bolt, there are diverse. To change and improve the bolt stress points between the thread friction locking product better results. But let locking effect is to achieve a better welding in use require professional welding improves the bolts installation of barriers and difficulty. Inventive content [0003] There is provided a rear fastening bolt and nut connection, the bolt has a nut engaging the external locking sleeve, the locking sleeve is connected with the effect of the surface by high-speed rotation, friction welding heat reaches the melt. At the same time, the locking sleeve is applied under pressure to the surface of bolt head or a nut, bolt or nut so that rotation can not be increased in the reverse direction, whereby the locking bolt play effect. [0004] To achieve the above o...
