Abstract
The utility model discloses a kind of dieback device of lockset, comprise dieback hammer, spring, connecting rod and dieback seat, described dieback hammer is fixed on connecting rod one end, and spring housing is on connecting rod, the connecting rod other end inserts in the endoporus of dieback seat, and the diameter of described connecting rod is slightly less than the diameter of dieback seat endoporus.It is simple that the utility model has structure, cheap, maneuverable feature.
Description
Technical field
The utility model relates to field of lockset, specifically a kind of dieback device of lockset.
Background technology
Be that the dieback device disclosing a kind of lockset in 201320671341.2 patents is made up of dieback pin and dieback cover in the patent No., dieback pin is made up of syringe needle, groups of springs, connecting rod and spring leaf, syringe needle is fixed on connecting rod one end, groups of springs is enclosed within connecting rod, the connecting rod other end is spring leaf, in the endoporus that spring leaf overlaps at dieback.In improper unblanking, spring leaf departs from the endoporus of dieback cover, opens under tension, on the outer ring surface that spring leaf dieback overlap at dieback, realizes the locking function locked.But in long-term use procedure, spring leaf is easily aging and fracture, thus shortens the application life of lockset.
Utility model content
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of dieback device of lockset, and it is simple that the utility model has structure, cheap, maneuverable feature.
The technical solution of the utility model is: a kind of dieback device of lockset, comprises dieback hammer, spring, connecting rod and dieback seat, and described dieback hammer is fixed on connecting rod one end, and spring housing is on connecting rod, and the connecting rod other end can insert in the endoporus of dieback seat.
Further according to the dieback device of a kind of lockset described in the utility model, the diameter of described connecting rod is slightly less than the diameter of dieback seat endoporus.
Figure of description
Fig. 1 is the dieback device schematic diagram of a kind of lockset of the utility model;
Fig. 2 is the locked schematic diagram that outer lock core dieback hole overlaps with internal cylinder spring eye;
In figure, 1-dieback is hammered into shape, 2-spring, 3-connecting rod, 4-dieback seat, 5-outer lock core, 6-internal cylinder, 7-spring eye, 8-spring pearl, 9-dieback hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail, to enable those skilled in the art's understanding clearly scheme of the present utility model, but does not therefore limit protection domain of the present utility model.
As shown in Figure 1, a kind of dieback device of lockset, comprises dieback hammer 1, spring 2, connecting rod 3 and dieback seat 4, described dieback hammer 1 is fixed on connecting rod 3 one end, spring 2 is enclosed within connecting rod 3, and connecting rod 3 other end can insert in the endoporus of dieback seat 4, and the diameter of connecting rod 3 is slightly less than the diameter of dieback seat endoporus.
As shown in Figure 2, operating principle of the present utility model: lockset comprises outer lock core 5 and internal cylinder 6, outer lock core 5 has dieback hole 9, dieback device is had in dieback hole 9, internal cylinder 6 has spring eye 7, when meeting with improper unblanking, internal cylinder 6 is rotated, when turning to certain angle, corresponding spring eye 7 overlaps with dieback hole 9, dieback hammer 1 is under the effect of spring 2 power, promotion dieback hammer 1 moves to the centerline direction of outer lock core 5, touch with the spring pearl 8 of internal cylinder 6, and continue to promote spring pearl 8 and move to the centerline direction of outer lock core 5, namely dieback hammer 1 can enter in the spring eye 7 of internal cylinder 6, simultaneously, connecting rod 3 is pushed out dieback seat 4 endoporus, because dieback hammers 1 injustice into shape, after contacting with the spring pearl 8 of internal cylinder 6 under it is by the active force of spring 2, connecting rod 3 rear end can be caused to offset, the center line of connecting rod 3 cannot be overlapped with the center line of dieback seat 4 endoporus, make dieback hammer 1 into shape cannot return in the endoporus of dieback seat 4.Now, internal cylinder 6 cannot be rotated, and also cannot promote the 1 outwards movement of dieback hammer by stirring spring pearl 8 simultaneously, namely achieving the locking function of lock.
Above the utility model is described in detail, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
