Problems solved by technology

[0002] In the fastening process of automobile production and mechanical equipment, ordinary bolts, nuts and elastic washers are usually used for fastening. The torque is gradually attenuated, and with the continuous vibration of the vibration source, the connecting nuts are loosened, and finally the nuts fall off, which leads to potential failures

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] figure 1 A schematic structural diagram of a bolt group according to an embodiment of the present invention is shown, which includes a bolt 1 and a nut 2, and the bolt 1 and the nut 2 are connected by common threaded locking. In order to prevent the loosening between the bolt 1 and the nut 2, the bolt group of the present embodiment adds an anti-loosening fastening sleeve 3, and the fastening sleeve 3 is arranged between the bolt head 1-1 and the nut 2, and the fastening A set of one-way ratchets are provided on the opposite end surfaces of the sleeve 3 and the nut 2 in the radial direction, and the two sets of ratchets are engaged, and the loosening direction of t...

Abstract

The invention relates to the technical fields of an automobile and machinery and discloses a bolt group. The bolt group comprises a bolt and a nut; a fastening sleeve is sleeved on a screw of the bolt; the fastening sleeve is arranged between the head part of the bolt and the nut; a group of one-way ratchets are respectively arranged on the opposite end faces of the fastening sleeve and the nut; two groups of ratchets are mutually meshed, and the loose directions of the ratchets on the end face of the nut are the same as the rotating direction of the nut fastened oppositely to the bolt. According to the bolt group, one matched fastening sleeve is added on the basis of a common bolt group; the fastening sleeve is matched with a flange nut, and the attached surface adopts a ratchet-type mounting surface, so that the nut reversely rotates difficultly after being forwards fastened by the nut. Therefore, the anti-loosing performance of the nut is greatly strengthened; the security of mounting mechanical parts is improved; the overall bolt group is simple in structure, convenient to mount and dismantle and strong in applicability.

Description

technical field [0001] The invention relates to the technical fields of automobiles and machinery, in particular to an anti-loosening fastening bolt group. Background technique [0002] In the fastening process of automobile production and mechanical equipment, ordinary bolts, nuts and elastic washers are usually used for fastening. The torque gradually attenuates, and with the continuous vibration of the vibration source, the connecting nuts are loosened, and eventually the nuts fall off, resulting in hidden troubles. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is how to avoid the loosening phenomenon of the nut during the fastening process. [0005] (2) Technical solutions [0006] In order to solve the above-mentioned technical problems, the present invention provides a bolt group, including bolts and nuts, the nuts and bolts are connected by thread locking, and a tightening sleev...
