Abstract
The utility model relates to a nut, in particular to a self-jam nut. The self-jam nut is characterized by comprising a nut body and an outer cover, wherein the outer part of the nut body is an entity, the inner part of the nut body is a first hollow core screwed with a bolt, the lower surface of the entity is a triangular structure from longitudinal section, the inner part and the outer part of the entity are provided with a plurality of screw threads with inverse directions, and the upper part of the entity is externally provided with a six-prism structure; and the outer cover is a cover body of which the inner part is provided with a second hollow core structure and the outer part is a cylindrical structure, the second hollow core structure fits with the nut body, the outer cover is internally provided with the screw thread which fits with the outer part of the nut body, and the lower part of the entity is provided with a plurality of spaced vertical openings. The self-jam nut with the structure has the advantages of being simple in structure, and good in locking effect.
Description
Technical field
The utility model relates to nut, and is particularly a kind of from jam nut.
Background technique
In order to lock, the technological scheme of taking has plenty of double nut stack and uses, and what have adds locking spiral shell pad etc., and such measure has the shortcoming that locks weak effect, the use anti-theft nut that also has, and such measure has complex structure, shortcoming that cost is high.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, provide a kind of have simple in structure, lock effective from jam nut.
The purpose of the utility model is achieved in that from jam nut; It is characterized in that: comprise nut body and overcoat; The outside of said nut body is that entity, inside have first hollow that is screwed into bolt, sees from longitudinal section, and be triangular structure below the described entity; Entity inside and outside has rightabout screw thread, and the entity exterior upper portion is six prism structures; Said overcoat inside has second hollow core structures, the outside is the body of round column structure, second hollow core structures nut body that coincide, and its external sleeve inside has the outside screw thread of identical nut body.
Say that further said otherwise solid lower portion has vertical openings at interval.
The beneficial effect of the utility model is: this spline structure from jam nut have simple in structure, lock effective advantage.
Description of drawings
Fig. 1 is the structural representation of nut body.
Wherein: 1, nut body 2, overcoat 3, entity 4, first hollow 5, second hollow core structures 6, vertical openings 7, six prism structures.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 1; From jam nut, it is characterized in that: comprise nut body 1 and overcoat 2, the outside of said nut body 1 is that entity 3, inside have first hollow 4 that is screwed into bolt; See from longitudinal section; Be triangular structure below the described entity 3, entity 3 inside and outside has rightabout screw thread, and entity 3 exterior upper portion are six prism structures 7; Said overcoat 2 inside have second hollow core structures 5, the outside is the body of round column structure, second hollow core structures 5 nut bodies 1 that coincide, and its external sleeve 2 inside have the outside screw thread of identical nut body 1.
When tightening; Six prism structures that can be above the nutting body, in second cavity of nut body its external sleeve since nut body inside and outside have anti-silk; In the time of can guaranteeing to tighten overcoat like this; What nutting body and overcoat combined more is tight more, and the acute angle portion of the triangular structure of entity shrinks, and holds the purpose that bolt plays the utility model tightly.
Say that further said otherwise solid lower portion has vertical openings at interval.
Say that further said otherwise solid lower portion has vertical openings 6 at interval, such opening can further play relaxation effect.
Claims (2)
1. from jam nut; It is characterized in that: comprise nut body and overcoat; The outside of said nut body is that entity, inside have first hollow that is screwed into bolt, sees from longitudinal section, and be triangular structure below the described entity; Entity inside and outside has rightabout screw thread, and the entity exterior upper portion is six prism structures; Said overcoat inside has second hollow core structures, the outside is the body of round column structure, second hollow core structures nut body that coincide, and its external sleeve inside has the outside screw thread of identical nut body.
2. nut according to claim 1 is characterized in that: said otherwise solid lower portion has vertical openings at interval.
