High-strength anti-falling groove-shaped nut

Abstract

The invention discloses a high-strength anti-falling groove-shaped nut. The nut comprises a nut main body, a flange gasket, lugs, shrinkage grooves, a threaded through hole, a check ring, a sealing ring and reinforcing grooves. Compared with the prior art, the nut is simple in structure, reasonable in design, the plurality of isosceles trapezoid-shaped reinforcing grooves are formed outside the nut main body, so that while the structural strength of the nut main body is enhanced, the total weight of the nut is reduced, the whole dynamic load or alternating load borne by the nut is reduced, andthe service life is prolonged; by arranging the lugs with arcs and inwards bent in cooperation with the shrinkage grooves between the lugs, so that the lugs are extruded inwards after the nut is locked, and looseness of the bolt connection seldom occurs; and the check ring, the sealing ring and an anti-slip pattern are arranged, so that the locking performance of the nut is further improved, andthe nut has an anti-loose and anti-falling function and is worthy of popularization.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to a high-strength anti-falling groove nut. 【Background technique】 [0002] Channel nut is a kind of nut, which is used to tightly connect two mechanical equipment. It is mainly used in occasions with vibration load or alternating load. It is used in conjunction with cotter pins to ensure the reliability of nut locking. It is often used as A locknut that prevents the main nut from coming back loose. [0003] At present, the hexagonal slot nuts used on the bolts are all integrated with the slot mother. After the nuts are tightened, the cotter pins are inserted from the slotted opening and the pin hole symmetrically at the end of the bolt to prevent loosening. The structural strength of the channel nut is low, and it does not have the function of anti-loosening and anti-loosening, which leads to loosening or even breaking of the bolt connection, affects the operation of the mecha...

Problems solved by technology

[0003] At present, the hexagonal slot nuts used on the bolts are all integrated with the slot mother. After the nuts are tightened, the cotter pins are inserted from the slotted opening and the pin hole symmetrically at the end of the bolt to prevent loosening. The existing The structural strength of the channel nut is low, and it does not have the function of anti-loosening and anti-loosening, which leads to loosening or even breaking of the bolt connection, affects the operation of the mechanical device, and even causes safety accidents. Therefore, it is necessary to propose a high-strength anti-loosening channel nut
