Abstract
The utility model relates to an omega elastic-strip anti-loose screw nut, which is manufactured to be integration by a flat washer and an M24 screw cap. The upper side, the lower side, the left side, and the right side at the bottom of the flat washer are respectively provided with two parallel anti-loose grooves, and two top and bottom parallel anti-loose grooves are respectively vertical and cross with two left and right parallel anti-loose grooves. The utility model is characterized in that the vertical cross point of the two top and bottom parallel anti-loose grooves and the two left and right parallel anti-loose grooves is provided with a one-way reverse 0.4*10 transition slope in precession direction, and a chamfer of the internal hole of the flat washer is 5*45. When the improved omega elastic-strip anti-loose screw nut is operated, when the omega elastic-strip anti-loose screw nut is screwed, resistance is reduced; the omega elastic-strip anti-loose screw nut which can not be clamped by screws is easy to screw in, and anti-loose effects are better.
Description
The utility model relates to rail fastening, and particularly a kind of plain washer and M24 nut join together, and the ω spring lock nut of ω spring channel profile contact is suitable for doing the rail fastening location, is particularly suitable for doing heavy steel rail fastener location.
Former, seamless railroad heavy steel rail fastener ω spring is by a kind of plain washer and M24 nut location.This kind structure is under heavy haul train acts on repeatedly, can cause that the surface friction drag between plain washer and the M24 nut reduces and plain washer and the change of ω spring force, influence using effect, our unit has applied for patent (ZL94239104.7) in 1994 for this reason, it is that plain washer and M24 nut are made one, about the bottom of plain washer, about have two parallel antiratchetting grooves, up and down two parallel antiratchetting grooves respectively with about two parallel antiratchetting grooves intersect vertically, during operation, the ω spring falls in the antiratchetting groove, this just makes the way of contact of ω elastic bar fastening and plain washer be contacted by planar point to become the corrugated surface contact, reach locking purpose.Yet, part still has some deficits in the patent working process, 1, up and down two parallel antiratchetting grooves respectively with about two parallel antiratchetting grooves intersect vertically, therefore resistance is bigger when tightening, 2, the chamfering at the plain washer endoporus of former patented product ω spring lock nut is 2 * 45 °, can be blocked by screw rod when ω spring lock nut is tightened.Both all influence nut screwing clamping.
For this reason, the purpose of this utility model is in order to overcome the shortcoming of ZL94239104.7 patent, to provide a kind of through improved ω spring lock nut.
The technical solution of the utility model is as follows: it is to make one by plain washer and M24 nut, about the bottom of plain washer, about have two parallel antiratchetting grooves, up and down two parallel antiratchetting grooves respectively with about two parallel antiratchetting grooves intersect vertically, be characterized in, up and down two parallel antiratchetting grooves respectively with about two parallel antiratchetting groove places of intersecting vertically fall 0.4 * 10 transitional slope for the precession direction is unidirectional; Hole chamfering is 5 * 45 ° in the plain washer.
Through improved ω spring lock nut, during operation, when tightening ω spring lock nut, resistance reduces, and can not blocked by screw rod, easily is screwed into, and anti-loosing effect is better.
The utility model is embodiment be described further in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation,
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 2 I;
Fig. 4 is a stereogram of the present utility model.
By Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made one by plain washer 2 and M24 nut 1, about the bottom of plain washer 2, about have two parallel antiratchetting grooves 3, up and down two parallel antiratchetting grooves respectively with about two parallel antiratchetting grooves intersect vertically, its intersection is unidirectional 0.4 * 10 transitional slope 5 that falls of precession direction; Hole chamfering 4 is 5 * 45 ° in the plain washer.
