Abstract
The utility model discloses a wedge reinforcement radial lock nut, and relates to a lock nut structure. The wedge reinforcement radial lock nut comprises a nut body, wherein an annular groove is formed in the side wall of the nut body; the side wall of the annular groove, close to the upper surface of the nut body, is provided with a slope; an annular groove is formed at the bottom of the annular groove close to the side wall with the slope; the annular groove is internally connected with a wedge matched with the annular groove through a screw nail; a plurality of strip-shaped grooves are formed in the upper surface of the nut body along the circumferential direction; the strip-shaped grooves are extended to the outer side wall of the nut body from a tapped hole in radial direction; and an elastic lock part is formed between the adjacent strip-shaped grooves. The nut body and the elastic lock parts are combined integrally, and a plurality independent elastic lock parts are provided, so that the locking is more reliable; through radial compaction, the wedge reinforcement radial lock nut is reliable to lock and convenient to dismantle during strong vibration impact loading; and without damaging the body and related connecting pieces, the wedge reinforcement radial lock nut has good practicability.
Description
Technical field
The utility model relates to a kind of locking nut structure, relates in particular to radially locking nut of a kind of voussoir reinforcement.
Background technique
Traditional round nut and little round nut adopt two round nut lockings, and when bearing the strong vibration impulsive load, locking is easily loosening, and making radially, rigid bearing and part etc. produce mobile.If adopting round nut+round nut locks with lock washer, need to open in the corresponding position lock washer keyway, destroy the structure of axle after splining on axle, increased the dynamic unbalance factor of axle, make the vibration of axle increase, after nut compresses, the lock washer locking plate often has deviation with draw-in groove, after the need adjusting nut in card entry slot.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides radially locking nut of a kind of voussoir reinforcement, its nut body and elastic locking section are integrated, have a plurality of independently elastic locking section, make locking more reliable, adopt radial compaction, reliable lock when the strong vibration impulsive load, and for convenience detach, do not damage body and related fittings, have good practicability.
The technical solution of the utility model is: a kind of voussoir reinforcement is locking nut radially, comprise nut body, described nut body sidewall has annular groove, described annular groove is gradient near the sidewall band of nut body upper surface, the annular groove bottom has annular groove near its sidewall with gradient, be connected by screw the voussoir that coordinates with annular groove in annular groove, the nut body upper surface circumferentially has some bar-shaped troughs along it, described bar-shaped trough radially extends to the nut body outer side wall from screw, forms elastic locking section between the adjacent bar groove.
As preferably, described bar-shaped trough is 6, and elastic locking section is 6.
The beneficial effects of the utility model are: nut body of the present utility model and elastic locking section are integrated, and have a plurality of independently elastic locking section, make locking more reliable.The voussoir reinforcement strengthens anti-loosening locking power; Unclamp screw during dismounting and get final product, do not damage body and related fittings.Adopt radial compaction, body and related fittings part all produce resiliently deformable, and reliable lock when the strong vibration impulsive load has good practicability.

Embodiment
As a kind of mode of execution of the present utility model, as shown in Figures 1 to 4, a kind of voussoir reinforcement is locking nut radially, comprise nut body 1, described nut body 1 sidewall has annular groove, described annular groove is gradient near the sidewall band of nut body 1 upper surface, and as preferably, the gradient of this sidewall is the 10-15 degree.The annular groove bottom has annular groove near its sidewall with gradient, be connected with by screw 3 voussoir 2 that coordinates with annular groove in annular groove, nut body 1 upper surface circumferentially has some bar-shaped troughs along it, described bar-shaped trough radially extends to nut body 1 outer side wall from screw, forms elastic locking section 4 between the adjacent bar groove.
In the present embodiment, as preferably, described bar-shaped trough is 6, becomes * shape to distribute, and elastic locking section 4 is 6.As preferably, be provided with two screws 3 in the annular groove between the adjacent bar groove.
Above to a kind of voussoir reinforcement provided by the utility model radially locking nut carried out detailed introduction, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To be possible to change of the present utility model and improvement, and can not exceed design and the scope that accessory claim can be stipulated.
Claims (2)
1. voussoir reinforcement locking nut radially, comprise nut body, it is characterized in that: described nut body sidewall has annular groove, described annular groove is gradient near the sidewall band of nut body upper surface, the annular groove bottom has annular groove near its sidewall with gradient, be connected by screw the voussoir that coordinates with annular groove in annular groove, the nut body upper surface circumferentially has some bar-shaped troughs along it, described bar-shaped trough radially extends to the nut body outer side wall from screw, forms elastic locking section between the adjacent bar groove.
