Description

Improved locknut

Technical Field

The utility model relates to a nut specifically is an improved generation locknut.

Background

The nut and the bolt are mechanical fixing pieces with wide application. When a common nut is matched with a bolt to fix a mechanical part, the nut is easy to loosen and fall off for a long time due to mechanical movement or vibration, so that a fixed part is displaced or loosened. Damage to mechanical parts may occur on a light basis and failure or accident may occur on a heavy basis. In order to solve the problem of loosening of the nut, people design a plurality of locknuts or devices aiming at different application conditions and environments, and the locknuts or the devices play a certain anti-loosening role to a certain extent.

However, the existing locknut is single in general structure, general in loosening effect, and inconvenient to popularize and use in a large range.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an improved generation locknut to the structure of proposing in solving above-mentioned background is comparatively single, also more general to the effect of relaxing of nut, is not convenient for problem of using widely on a large scale.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides an improved generation locknut, includes the nut body, threaded hole has seted up on the nut body, threaded hole department has seted up the draw-in groove, be provided with the kelly in the draw-in groove, nut body bottom is provided with a plurality of complementary unit along the circumference equidistance, complementary unit includes jack catch, claw head and arc wall, be provided with the ribbon in the arc wall.

As a further aspect of the present invention: the threaded hole is provided with an internal thread, and the internal thread on the threaded hole is matched with the external thread on the bolt.

As a further aspect of the present invention: the clamping rod is matched with the clamping groove, and a groove used for matching the clamping rod is formed in the bolt corresponding to the clamping groove.

As a further aspect of the present invention: and one end of the clamping jaw is hinged to the bottom of the nut body through a hinged seat, and the other end of the clamping jaw is fixedly connected with the jaw head.

As a further aspect of the present invention: the claw head is arranged obliquely.

As a further aspect of the present invention: the arc-shaped groove is formed in the outer side of the clamping jaw.

Compared with the prior art, the beneficial effects of the utility model are that:

carry out threaded connection through the setting with the nut body through the internal thread on the screw hole and the external screw thread of bolt, further through insert the kelly in the draw-in groove and in the recess on the bolt, further the bottom card that drives the claw head through the jack catch in the rotatory complementary unit drives in the thread groove of the external screw thread of bolt, further establish in the arc wall in a plurality of complementary units through establishing the ribbon, further through taut ribbon, thereby make the articulated rotatory claw head that drives of jack catch among a plurality of complementary unit remove to bolt department, thereby make the nut possess dual relaxation measure, the effect of relaxing of nut has been improved greatly, the personnel of being convenient for use widely on a large scale.
