Description

A kind of lockset that automatically resets

Technical field

The utility model relates to a kind of haberdashery and hardware lockset, the automatically reset lockset of two steel ball dead bolt types of the lock core that relates in particular to a kind of good anti-theft effect, long service life.

Background technology

Because lock core the inner of traditional padlocks is not provided with a kind of back-moving spring of new structure, inserting lock core at key turns in the process, the returning of compression process bounce-back that conventional is relies on the dead bolt spring tried hard to recommend moving dead bolt the lock core foot revolution resetted, its shortcoming is very flexible, easily dead bolt and lock core foot is broken away from, and the lock core Recovery Process is not in place, turns round unable, its lock core anglec of rotation is little, the scope of application is restricted, and anti-theft effect is bad, operation is stiff not convenient, and application life is short.Research and development of the present utility model have overcome this technological deficiency, have filled up the blank in this field.

The utility model content

In order to overcome the defective in the existing padlock technology, the utility model provides a kind of long service life, has operated the lockset that automatically resets convenient, applied widely, good anti-theft effect.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of lockset that automatically resets comprises lock body, lock core, latch bolt spring, steel ball, and the polymorphic structure back-moving spring of connection one novel development bottom the lock core hole of lock body.

One end of described back-moving spring is embedded on the lock core, the other end plant with lock body on.

Respectively there is a semi-circular recesses at the two ends of described plug keyway, when lock is opened, two steel ball shape dead bolts can be automatically reset in the groove of lock core, when closed, will be along with the twisting resistance of back-moving spring, the steel ball tongue will break away from the lock core groove, be pushed to automatically in the semi-circular recesses of lock bridge.

The beneficial effects of the utility model are, practicality is stronger, operation is convenient, the lock core anglec of rotation can automatically reset in 145 degree, and the power of returning is powerful, turns easily (the conventional lock core anglec of rotation is in 65 degree), applied widely, anti-theft effect is better, longer service life.

Description of drawings

Fig. 1 is the utility model closure state structural representation;

Fig. 2 is the utility model opening structural representation.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

A kind of lockset that automatically resets comprises that a lock body 1, is embedded in the lock core 2 at this lock body 1 center, at the bottom of this lock core 2 socket one back-moving spring 3, steel ball shape dead bolt 4, lock bridge 5.

One end of described back-moving spring 3 is embedded on the lock core 2, and the other end is implanted on the lock body 1.

Respectively there is a semi-circular recesses at the two ends of described lock core 2 key, when lock is opened, two steel ball shape dead bolts 4 can be automatically reset in the groove of lock core 2, when closed, will be along with the twisting resistance of back-moving spring 3, steel ball tongue 4 will break away from the lock core groove, be pushed to automatically in the semi-circular recesses of lock bridge 5.

During use, along with key inserts in the lock core 2, in the process that turns, lock body 1 is fixing, and lock core 2 turns over required certain angle≤145 ° along with the rotation of key, and at this moment back-moving spring 3 is in the state of tightening up, at the steel ball shape dead bolt 4 at two ends, lock core 2 left and right sides under the promotion of lock bridge spring 6, move past in the journey on the lock bridge 5, steel ball shape dead bolt 4 changes in the arc groove that advances lock core 2 automatically, causes lock bridge 5 normally to be opened.

After lock bridge 5 closures, under the contraction tension return action of the steel ball shape dead bolt 4 at lock core 2 two ends along with back-moving spring 3, passed by the rotation of lock core 2 in the groove of lock bridge 5, and the unlatching spring of inhibition lock bridge 5, lock core 2 also is returned to initial state thereupon voluntarily simultaneously, its antitheft effectiveness is to prevent dialling tension, because stir steel ball shape dead bolt, 90 ° of essential rotational lock cores, and want both sides to stir simultaneously, just might open, be difficult to so almost can't accomplish this measure, so effect and intervention that it effectively avoids external force have realized hommization, have really reached anti-theft effect.

During assembling, earlier lock bridge spring 6 and lock bridge 5 are put into lock beam hole, after steel ball shape dead bolt 4 is put in lock core 2 holes, through horizontal dead bolt hole respectively about each one place in the corresponding lock bridge groove, suppressing lock bridge 5 jumps out automatically, again automatic-reset spring 3 one ends are planted in the left aperture of the lock core hole bottom of lock body 1, after lock core 2 is vertically put into lock core hole, and the other end inlay card that makes automatic-reset spring 3 is in the groove of lock core 2, under the prerequisite that preliminary operation kinetic energy is replied voluntarily, to number put into corresponding hoodle and spring by the tartar of key respectively in the pellet shot from a slingshot hole of lock core 2 again, even if back sealing of hole installation is inserted key and turned, can open padlock, during the closure lock bridge, lock core 2 just can automatically reset to initial state.

The utlity model has practical, applied widely, good anti-theft effect, long service life etc. advantage is arranged.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to the embodiment of wooden utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.

Claims (2)
