The invention discloses a torsion type nondestructive installation self-locking mechanism, comprising a concave end and a convex end; the inner wall of the concave end is provided with a plurality of guiding grooves; the convex end is provided with convex point structures which can be inserted into the guiding grooves correspondingly, and the convex end can be inserted into the concave end along the convex point structures through the guiding grooves; and the bottom of the concave end is provided with an annular groove. When the torsion type nondestructive installation self-locking mechanism is assembled, the structure of a matched hole is not damaged, therefore, the assembling strength is improved, the damage to the structure of an interference fit mechanism is reduced in assembling, and the material consumption of the structure is reduced.
Description
Technical field
The present invention relates to a kind of structural member, be specifically related to a kind of self-locking deduction structure.
Background technique
At present, as shown in Figure 1, there is interference fit in existing self-locking deduction structure when installing, and press-fits process destructible matching hole structure, and assembling intensity is subject to the interference size.The traditional locks buckle structure when mounted, female end interference part is easily by the support distortion of rising, even breaks.
Summary of the invention
Technical problem to be solved by this invention provides the harmless self-locking deduction structure of installing of a kind of torsional mode, and it can not destroy the matching hole structure, reduces interference fit mechanism destruction to self structure when assembling.
In order to solve above technical problem, the invention provides the harmless self-locking deduction structure of installing of a kind of torsional mode; Comprise: inwall has the female end of a plurality of guiding grooves; With the corresponding male end of inserting the guiding groove bump structure, described male end can be inserted female end by guiding groove along bump structure; Annular slot is arranged at described female end bottom.
Beneficial effect of the present invention is: do not destroy the matching hole structure during assembling, improved assembling intensity, reduced interference fit mechanism destruction to self structure when assembling, reduced the materials consumption of this kind structure.

Embodiment
The harmless self-locking deduction structure of installing of torsional mode of the present invention; Comprise: inwall has the female end 2 of a plurality of guiding grooves 1; With the corresponding male end 4 of inserting guiding groove 1 bump structure 3, described male end 4 can be inserted female end 2 by guiding groove 1 along bump structure 3; Trapezoidal annular slot 5 is arranged at described female end 2 bottoms.Described guiding groove 1 shape in the shape of a spiral extends downwards, and its bottom communicates with annular slot 5.Distance equates between described many guiding grooves 1.Described as shown in FIG. guiding groove is 4, and corresponding bump structure is 4, and in fact guiding groove 1 can be for a plurality of arbitrarily, and the number of bump structure 3 is corresponding with the number and the position of guiding groove 1 with the position.Restraining groove 6 or positive stop key 7 are arranged on described female end 2 or the male end 4.When single cover snap close is used, when not having other mechanisms that can limit the relative movement of male and female end, need fit applications restraining groove 6 and positive stop key 7.During a plurality of applied in any combination of described latching device, can omit restraining groove 6 or positive stop key 7 on female end or the male end.As shown in FIG., on the described female end 2 restraining groove 6 is arranged, corresponding positive stop key 7 is arranged on the described male end 4, also can on described female end 2, positive stop key 7 be set, corresponding restraining groove 6 is set on the described male end 4.Described male end can be cylindrical-shaped structure, and described female end can be cylinder-like structure.
In the above-mentioned snap close: described latching in when assembling, the bump structure 3 of male end 4 heads enters female end 2 inside along the guiding groove 1 of female end 2, and drive male end 4 stage casing parts are reversed.When the bump structure 3 of male end 4 heads enters the trapezoidal annular slot 5 of female end 2 fully, the reverse part spring-go in male end 4 stage casings, bump structure 3 rotates away from guiding groove 1 thereupon.Because the external diameter that some bump structures 3 are combined into is greater than female end 2 internal diameters, male end 4 can't be separated with female end 2; When two covers or the above snap close of two covers were used simultaneously, male end 4 and female end 2 did not have relative movement; When using, single cover snap close, must increase positive stop key 7 and restraining groove 6 structures for preventing rotation.
Assembling of the present invention the time does not destroy the high strength self-locking deduction structure of matching hole structure, and assembling intensity has improved in this mechanism, reduced interference fit mechanism when assembling to the destruction of self structure, reduced the materials consumption of this kind structure.
Fig. 2 is female end 2 form structure, and guiding groove 1 is in inside, female end 2 aperture;
Fig. 3 is male end 4 form structure, on the male end 4 lower end flange plate bump structure 3 is arranged;
Fig. 4 is female end 2 internal structures, guiding groove 1 oblique being arranged in the hole wall, and trapezoidal annular groove 5 structures are arranged at the bottom, hole.
During the assembling beginning, as shown in Figure 5, the salient point 3 of male end head is aimed at the inlet of female end guiding groove 1 respectively;
In the assembly process, as shown in Figure 6, the salient point 3 of male end head, and drives male end stage casing part and reverses to downslide along female end guiding groove 1.
Assembling is finished, and as shown in Figure 7, male end head salient point 3 with former reverse part spring-go, rotates to from position, the terminal d place of guiding groove in trapezoidal ring band 5 territories, and the external diameter that is combined into owing to bump structure 3 is greater than female end 2 apertures, and the male and female end can't separate.
This latching device when mounted, male end 4 head bump structures 3 enter female end 2 inside by guiding groove 1.When male end 4 heads during near female end 2 bottoms, male end 4 head bump structures 3 break away from guiding grooves 1, spring-go rotation in the trapezoidal annular groove 5 in female end 2 bottoms, and bump structure 3 cooperates the formation contra bevel with trapezoidal annular groove 5 inclined-planes, make male end 4 can't break away from female end 2.This structure when guaranteeing assembling intensity, reduced interference fit mechanism when assembling to the destruction of self structure, reduced the materials consumption of this kind structure.
The present invention is not limited to mode of execution discussed above.More than the description of embodiment is intended in order to describe and illustrate the technological scheme that the present invention relates to.Based on the conspicuous conversion of the present invention enlightenment or substitute and also should be considered to fall into protection scope of the present invention.Above embodiment is used for disclosing best implementation methods of the present invention, so that those of ordinary skill in the art can use numerous embodiments of the present invention and multiple alternative reaches purpose of the present invention.
