Structure for preventing nut from loosening

Abstract

The invention discloses a structure for preventing a nut from loosening, and relates to the field of nut loosening prevention. The structure comprises a first locked object, a second locked object, a screw and the nut; a first through hole is formed in the first locked object, a second through hole is formed in the second locked object, and the nut is in threaded connection with the outwards-protruding part of the screw; the structure further comprises an anti-rotation insert and an elastic device; a plurality of clamping grooves which are sunken in the axis direction are formed in the outer wall of the nut in an annular array mode, so that a circle of teeth can be formed on the outer wall of the nut; the elastic device is arranged on one side of the nut and drives one end of the anti-rotation insert to be inserted into any clamping groove of the nut, and the end, inserted into the clamping groove, of the anti-rotation insert comprises an inclined surface, so that the nut can only rotate in the locking direction, and the other rotation direction of the nut is jammed by one end of the anti-rotation insert. The problem that the nut and the screw are loosened due to vibration is mainly solved.

Description

technical field [0001] The invention relates to the technical field of nut loosening prevention structures, in particular to a structure for preventing nuts from loosening. Background technique [0002] The existing way of fixing two workpieces is usually to fix them together with screws and nuts. However, due to the working environment or other factors, the two workpieces will vibrate. At this time, the connection between the screws and the nuts may become loose, thus As a result, the two workpieces are loose, and the locked state cannot be reliably maintained, which may lead to a series of problems, especially because some structures are too compact and require dismantling many parts to re-tighten the two loose workpieces. If it is fixed, it will lead to problems such as high maintenance costs and affecting product production efficiency. Of course, there are also many anti-loosening nut structures on the market, but the design of these structures is not clever enough to e...

[0002] The existing way of fixing two workpieces is usually to fix them together with screws and nuts. However, due to the working environment or other factors, the two workpieces will vibrate. At this time, the connection between the screws and the nuts may become loose, thus As a result, the two workpieces are loose, and the locked state cannot be reliably maintained, which may lead to a series of problems, especially because some structures are too compact and require dismantling many parts to re-tighten the two loose workpieces. If it is fixed, it will lead to problems such as high maintenance costs and affecting product production efficiency.

Of course, there are also many anti-loosening nut structures on the market, but the design of these structures is not clever enough to ensure the stability and reliability of the mechanical structure for a long time, has the disadvantage of not being durable, and sometimes cannot meet specific use requirements
