Abstract

Disclosed is an anti-loosening sleeve (1) with no pre-tightening force, comprising a bolt body (2) with a hole (2.1) and an elastic anti-loosening sleeve (1) sheathed on the end of the bolt body, wherein an elastic strip (1.1) is provided on the anti-loosening sleeve, a boss (1.1A) is provided on the elastic strip, and the boss and the hole on the bolt body cooperate such that when the boss is inserted in the hole, the anti-loosening sleeve is fixed and when the boss and the hole are dislocated, the anti-loosening sleeve can be removed from the bolt body.

Description

technical field [0001] The invention relates to a mechanical connection anti-loosening device, in particular to an anti-loosening sleeve connected by a non-pretightening force bolt. Background technique [0002] In daily life or production equipment and facilities, there are a large number of mechanical connections, including some bolted connections. Bolt connection The most common threaded bolt connection is called bolt connection, and there are some non-threaded bolt connections, such as door bolts in daily hardware. There are many anti-loosening methods for bolted connections at present, which are introduced in 3.2 "Common anti-loosening methods for threaded connections" in Chapter 1, Section 3, Chapter 1, Volume 2 of "Mechanical Design Manual" (Fifth Edition). Mainly include: spring washers, wave elastic washers, tapered lock washers, double nuts, nylon ring lock nuts, spierlock nuts, bolt shank with holes and slotted nuts with cotter pins, stop rings, and steel wires i...
