Abstract
The invention relates to a moving device in a lock protective plate; a moving sheet (4) is mounted in the protective plate; a slide groove is formed in the moving sheet (4); a column body is fixed on the protective plate by the slide groove; a spring (3) is fixed on the moving sheet (4) by a middle shaft; two ends of the spring (3) are supported on the column body; lock holes are respectively formed in the moving sheet (4) and the protective plate; the lower end of the protective plate is provided with a connecting rod mechanism (1); and a cam mechanism (2) is arranged in the slide groove of the lower end of the protective plate. According to the invention, lock cores can be effectively shielded and the lock cores can be prevented from being out of control and stolen due to exposure.
Description
Technical field
The present invention relates to mobile device in a kind of lockset backplate, specifically it can be used to block lock core.
Background technology
On the lockset backplate that often uses in the market the lock core hole that exposes is arranged, can see lock core by lock core hole, and exposing of lock core is namely not attractive in appearance not dustproof, then can cause lock core to lose efficacy if any foreign matter in the lock core, make troubles for people's life, main is to cross the threshold to steal to the robber to provide convenience.
Summary of the invention
In order to solve because lock core exposes the problem that causes lock core to lose efficacy, the invention provides mobile device in kind of the lockset backplate, this device can effectively block lock core by movement and prevent that lock core lost efficacy.
For reaching above purpose, the technical scheme that the technical problem that the present invention solves adopts is: this device is made of moving sheet and a cover cam link mechanism, moving sheet can be installed in the backplate, and by cam link mechanism realization locking and unlatching, move up and down thereby connect the realization moving sheet by spring between the connecting rod.
The object of the present invention is achieved like this: mobile device in a kind of lockset backplate, moving sheet is installed in the backplate, described moving sheet is provided with chute, cylinder is fixed on the backplate by chute, spring is fixed on the moving sheet by axis, and both ends of the spring is supported on the cylinder, is respectively equipped with lockhole on moving sheet and the backplate, the backplate lower end is provided with linkage, and the chute of lower end is provided with cam mechanism.
Moving sheet of the present invention, linkage are flexibly connected by cylinder and backplate; Linkage is provided with and tightens up spring, and the linkage two ends are set on the cylinder, and cylinder is fixed on the backplate by chute; The backplate bottom is provided with electric control gear, and the axis of described electric control gear is corresponding with the linkage axis; Spring is fixed on the moving sheet by rivet or screw.
After adopting above technical scheme, the invention has the beneficial effects as follows: can effectively block lock core, prevent from that lock core from exposing to cause lock core to lose efficacy and the event of having things stolen occurs, handsome in appearance, safe and reliable, economical and practical.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the state diagram of the present invention when locking.
The specific embodiment
According to shown in Figure 1, mobile device in a kind of lockset backplate of the present invention, moving sheet 4 is installed in the backplate, described moving sheet 4 is provided with chute, and cylinder is fixed on the backplate by chute, and spring 3 is fixed on the moving sheet 4 by axis, spring 3 two end supports are on cylinder, be respectively equipped with lockhole on moving sheet 4 and the backplate, the backplate lower end is provided with linkage 1, and the chute of lower end is provided with cam mechanism 2.
Moving sheet 4 of the present invention, linkage 1 are flexibly connected by cylinder and backplate; Linkage 1 is provided with and tightens up spring 6, and linkage 1 two ends are set on the cylinder, and cylinder is fixed on the backplate by chute; The backplate bottom is provided with electric control gear 5, and the axis of described electric control gear 5 is corresponding with linkage 1 axis; Spring 3 is fixed on the moving sheet 4 by rivet or screw.
When External Force Acting, moving sheet 4 moves down, and tightens up spring 6 and shrinks inward, and pulling linkage 1 two ends are slipped to 2 li of cam mechanisms, and linkage 1 pins moving sheet 4, makes the dislocation of lock core and lockhole, thereby shelters from lock core.
According to shown in Figure 2, bump linkage 1 makes linkage 1 two ends leave cam mechanism 2 when electric control gear 5 energising, and moving sheet 4 can be promoted move up by spring 3, the lockhole on the moving sheet is overlapped with lockhole on the backplate, thereby can normally unblank.
