Abstract
A kind of spring detent, comprise draw ring, bearing pin, nut, axle sleeve, spring, described nut is fixed on one end of axle sleeve by screw thread, the other end of axle sleeve is welded on the pilot hole place of workpiece, and described bearing pin is thickness two sections, and spring housing is at the thin shaft part of bearing pin, the thin axle head of bearing pin is through axle sleeve, pierce into nut, spring is limited between nut and the thick shaft part of bearing pin, and the thin axle head that bearing pin pierces into nut is connected with draw ring.The beneficial effects of the utility model are: design outline is attractive in appearance, easy to operate, connect rapidly, and during assembling workpiece, only Kong Yukong need be alignd, bearing pin will penetrate in hole under the action of the spring automatically, is linked together by two assemblies.Because spring detent is welded on an assembly, therefore when dismounting two assembly parts, as long as the draw ring of the spring detent that pulls outward just can make two assembly parts be separated, repeatedly need not dismantle bearing pin, time saving and energy saving.Make the hinged dismounting operation of large-scale assembly parts more convenient.
Description
Technical field
The utility model relates to a kind of fastening piece be articulated and connected for assembly parts, particularly relates to a kind of spring detent.
Background technique
When two assembling workpiece need to be articulated and connected time, be use pinned connection under normal circumstances, when using bearing pin assembling, two people are often needed to coordinate assembling, the Kong Yukong of two assembly parts aligns by a people, and another person inserts bearing pin, safety pin, very time-consuming and artificial.Especially when the large-scale assembling workpiece of dismounting, because assembly parts weight is all heavier, needing many people to coordinate when mounting and dismounting, wasting time and energy especially.
Summary of the invention
The purpose of this utility model is to provide a kind of spring detent, and structure is simple, easy to operate, is easy to the installing/dismounting of assembly parts, makes the hinged dismounting operation of large-scale assembly parts more convenient.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of spring detent, comprise draw ring, bearing pin, nut, axle sleeve, spring, described nut is fixed on one end of axle sleeve by screw thread, the other end of axle sleeve is welded on the pilot hole place of workpiece, and described bearing pin is thickness two sections, and spring housing is at the thin shaft part of bearing pin, the thin axle head of bearing pin is through axle sleeve, pierce into nut, spring is limited between nut and the thick shaft part of bearing pin, and the thin axle head that bearing pin pierces into nut is connected with draw ring.
Be provided with through hole in described nut, wide-aperture one end is provided with internal thread, and one end of small aperture is provided with straight groove.
The thin axle head of described bearing pin is provided with draw ring hole.
Described draw ring there is opening.
Compared with prior art, the beneficial effects of the utility model are:
1) design outline is attractive in appearance, easy to operate, connects rapidly, and during assembling workpiece, only Kong Yukong need be alignd, bearing pin will penetrate in hole under the action of the spring automatically, makes two assemblies link together in a short period of time.
2) because spring detent is welded on an assembly, therefore when dismounting two assembly parts, as long as the draw ring of the spring detent that pulls outward just can make two assembly parts be separated, repeatedly need not dismantle bearing pin, bring a lot of convenience to operator, time saving and energy saving.
3) make the hinged dismounting operation of large-scale assembly parts more convenient.

Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following mode of execution.
As Figure 1-Figure 2, a kind of spring detent, comprise draw ring 1, bearing pin 2, nut 3, axle sleeve 4, spring 5, nut 3 is fixed on one end of axle sleeve 4 by screw thread, and the other end of axle sleeve 4 is welded on the pilot hole place of assembly parts, bearing pin 2 is thickness two sections, spring 5 is enclosed within the thin shaft part of bearing pin 2, and the thin axle head of bearing pin 2, through axle sleeve 4, pierces into nut 3, spring 5 is limited between nut 3 and the thick shaft part of bearing pin 2, and the thin axle head that bearing pin 2 pierces into nut 3 is connected with draw ring 1.
Be provided with through hole in nut 3, wide-aperture one end is provided with internal thread, and one end of small aperture is provided with straight groove 7.
The thin axle head of bearing pin 2 is provided with draw ring hole 6.
Draw ring 1 there is opening.
One end that axle sleeve 4 is connected with nut 3 is processed with outside thread.
The assembly method of a kind of spring detent of the utility model is as follows:
1) nut 3 is screwed on the outside thread of axle sleeve 4.
2) be enclosed within the thin shaft part of bearing pin 2 by spring 5, the thin axle head of bearing pin 2, through axle sleeve 4, pierces in the through hole of nut 3, and now spring 5 is limited between nut 3 and the thick shaft part of bearing pin 2.
3) by the straight groove 7 of the draw ring 1 insert nut the other end, break the opening of draw ring 1 into two with one's hands, make draw ring 1 penetrate bearing pin 2 from the two ends in draw ring hole 6.
See Fig. 3, using method of the present utility model is as follows:
1) first the free end of spring detent axle sleeve 4 is weldingly fixed on the pilot hole place of peripheral equipment accessory 8.
2) pull draw ring 1, make in bearing pin 2 holddown spring 5 indentation axle sleeve 4.
3) two assembly parts are close to assembling, the relative position of mobile two assembly parts, makes pilot hole align, and now bearing pin 2 can stretch out axle sleeve 4 under the effect of spring 5, automatically penetrates in two pilot holes, is articulated and connected by two assembly parts.
4) when workpiece needs dismounting, only bearing pin 2 need be drawn in axle sleeve 4 by draw ring 1, two assembly parts can be made to separate by nature.
