[background technique]
Nut is the fastener for having internal screw thread and being used cooperatively with bolt, with internal screw thread.Conventional nut it is locking
Method be usually under the nut face increase a washer, increasing friction force extends fastening service life of nut, this conventional method energy
The frictional force enough increased is far from enough, failure is easy, in addition, the traditional curing mode of bolt, nut is applied on bolt, nut
Antirust oil or paint to prevent it from getting rusty, but be coated in antirust oil above or paint will loss by dissolution, this will result in ring
Border pollution, and also periodically to go to safeguard again, cause maintenance cost to increase, therefore propose a kind of locking nut.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, propose a kind of locking nut, can prevent nut with
Relative rotation between bolt to reach locking purpose, and is able to solve nut to be chronically exposed to rust-proof effect in air poor
The problem of.
To achieve the above object, the invention proposes a kind of locking nuts, including hex nut body, connector, locking body
And shield, the top of the hex nut body are equipped with connector, the outer wall of the connector is equipped with screw thread, the shield
Inner wall is equipped with installation convex edge, and the installation convex edge includes mounting portion and driving portion, and the inner wall of the mounting portion is equipped with screw thread, described
Cooperation is threadedly coupled between connector and mounting portion, the top of the connector is equipped with locking body, the locking body and driving portion
It matches, the driving portion control locking body radially inside contracts.
Preferably, the locking body is distributed in uniform circular, slot is equipped between the locking body, the locking body
Outer wall is equipped with voussoir, and the junction of the voussoir and connector is equipped with constriction annular groove, and the inner wall of the driving portion is equipped with driving cone
Face, the voussoir are matched with the driving conical surface.
Preferably, the lower end surface of the shield is equipped with the first sealing ring, the end face of the hex nut body is equipped with
Second sealing ring.
Preferably, seal groove is offered between the upper surface and connector of the hex nut body, in the seal groove
Third sealing ring, the lower end surface tight fit of the third sealing ring and installation convex edge are installed.
Preferably, the cross sectional shape of the shield is circle, circle is straight where the lower end surface section of the shield
Diameter is greater than the cornerwise length of hex nut body section, and the top of the shield is equipped with block cover, and the shape of the block cover is half
It is spherical.
Beneficial effects of the present invention: the present invention is by combining hex nut body, connector, locking body and shield etc.
Be used together, can be improved the coupling mechanism force between nut and bolt, the relative rotation both avoided, achieve the purpose that it is locking,
The structure of multiple sealing rings is set on shield and nut body, can effectively improve whole leakproofness, effectively avoid spiral shell
The problem of mother is got rusty.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
