The specific embodiment

The harmless self-locking deduction structure of installing of torsional mode described in the utility model; Comprise: inwall has the female end 2 of a plurality of gathering sills 1; With the corresponding male end 4 of inserting gathering sill 1 bump structure 3, described male end 4 can be inserted female end 2 by gathering sill 1 along bump structure 3; Trapezoidal endless groove 5 is arranged at described female end 2 bottoms.Described gathering sill 1 shape in the shape of a spiral extends downwards, and its bottom communicates with endless groove 5.Distance equates between described many gathering sills 1.Described as shown in FIG. gathering sill is 4, and corresponding bump structure is 4, and in fact gathering sill 1 can be for a plurality of arbitrarily, and the number of bump structure 3 is corresponding with the number and the position of gathering sill 1 with the position.Stopper slot 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 motion of male and female end, need fit applications stopper slot 6 and positive stop key 7.During a plurality of applied in any combination of described latching device, can omit stopper slot 6 or positive stop key 7 on female end or the male end.As shown in FIG., on the described female end 2 stopper slot 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 stopper slot 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 gathering sill 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 endless groove 5 of female end 2 fully, the reverse part spring-go in male end 4 stage casings, bump structure 3 rotates away from gathering sill 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 motion; When using, single cover snap close, must increase positive stop key 7 and stopper slot 6 structures for preventing rotation.

Assembling described in the utility model the time does not destroy the high strength self-locking deduction structure of mating holes structure, and assembling intensity has improved in this mechanism, reduced interference fit mechanism when assembling to the destruction of self structure, reduced the material consumption of this kind structure.

Fig. 2 is female end 2 contour structures, and gathering sill 1 is in inside, female end 2 aperture;

Fig. 3 is male end 4 contour structures, on the male end 4 lower end flange bump structure 3 is arranged;

Fig. 4 is female end 2 internal constructions, gathering sill 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 gathering sill 1 respectively;

In the assembling 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 gathering sill 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 gathering sill 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 gathering sill 1.When male end 4 heads during near female end 2 bottoms, male end 4 head bump structures 3 break away from gathering sills 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 material consumption of this kind structure.

The utility model is not limited to embodiment discussed above.More than the description of the specific embodiment is intended in order to describe and illustrate the technical scheme that the utility model relates to.Based on the conspicuous conversion of the utility model enlightenment or substitute and also should be considered to fall into protection domain of the present utility model.The above specific embodiment is used for disclosing best implementation method of the present utility model, so that those of ordinary skill in the art can use numerous embodiments of the present utility model and multiple alternative reaches the purpose of this utility model.
