Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The special anti-loosening nut for motor vehicles consists of a main nut 1, a limit screw 2, a limit screw hole 3, 502 glue 4, a crushing groove 5, a rubber storage strip 6, an auxiliary nut 7, a top pressure ring 8, a glue discharge hole 9 and Ring groove 10 constitutes.

[0020] Wherein, the interior of the main nut 1 has a longitudinally through screw hole. On the bottom surface of the main nut 1, there is an annular crushing groove 5 with a rectangular cross section. The upper half of the main nut 1 is hexagonal, and the lower half of the main nut 1 is cylindrical. The outer wall of the cylindrical It is threaded and has a transverse limit screw hole 3 , the inner end of the limit screw 2 is in the limit screw hole 3 , and the outer end of the limit screw 2 is directly above the auxiliary nut 7 .

[0021] The auxiliary nut 7 is cylindrical ...

Abstract

The invention relates to the technical field of motor vehicle accessories, in particular to a lock nut special for a motor vehicle. The lock nut special for the motor vehicle is composed of a main nut, a limiting bolt, a limiting screw hole, 502 glue, a broken groove, a glue storage bar, an auxiliary nut, a top pressure ring, a glue discharging hole and a ring groove. The broken groove which is annulus and provided with a rectangular cross section is formed in the bottom face of the main nut, the upper half portion of the main nut is in a hexagon shape, the lower half portion of the main nut is in a cylindrical shape, the outer side wall of the cylindrical shape is provided with threads and the transverse limiting screw hole, the upper end of the auxiliary nut is sleeved on the lower end of the main nut and combined with the main nut in a threaded mode, the ring groove which is provided with a rectangular cross section is formed in the upper surface of the bottom portion of the auxiliary nut, the lower end of the top pressure ring of the cylindrical shape is placed in the ring groove and the upper end of the top pressure ring is placed in the broken groove and in clearance fit with the broken groove in a gapped mode.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a special anti-loosening nut for motor vehicles. Background technique [0002] Existing auto parts, all relying on the combination of screws and nuts to achieve fastening, will inevitably loosen due to long-term vibration during the long-term driving of the car. It is a very tedious task to regularly detect and strengthen the nuts of auto parts for looseness. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a special anti-loosening nut for motor vehicles that can be tightly combined with the nut during the assembly process to eliminate the hidden danger of loosening. [0004] The scheme that solves technical problem of the present invention is: [0005] The special anti-loosening nut for motor vehicles is composed of a main nut, a limit screw, a limit screw hole, 502 glue, a crushing groove, a rubber sto...
