Description

The unconfined lockset of key turns angle

Technical field

The utility model relates to a kind of lockset.

Background technology

Key inserts in lockset, when mating with lock core, can be with key tooth flower movable lock core to rotate, conventional lockset key when key tooth flower does not mate with lock core generally turns motionless, also there is at present the unconfined lockset of some key turns angles to dally at any angle, be key tooth flower while not mating with lock core key ceaselessly dally and lock core does not turn, lockset still cannot be opened.The lock core positioning device of the unconfined lockset of existing key turns angle is all that pin is installed in boring on lock body, with pin, locate to control the angle of lock core rotation, deficiency is that installation procedure is many, especially pin one end is exposed at outside lock body, affect the planeness of surface of lock body, affect the quality on lockset surface, safety is also low; In addition, existing blade is all that working (machining) efficiency is lower by being manually placed in blade cover, all will putting by note face while putting blade, requiring operative employee to have good eyesight.

Summary of the invention

Goal of the invention of the present utility model is to overcome above-mentioned technological deficiency, and a kind of novel structure is provided, and produces the unconfined lockset of key turns angle easy to assembly, safe, production efficiency is high.

To achieve the above object, the utility model has adopted following technical scheme:

The unconfined lockset of key turns angle, comprise lock body and interior lock core and lock core positioning device thereof, lock core is arranged in the lock core hole in lock body, lock core comprises blade cover, blade and lock bolt sheet, blades installation is in blade cover, and lock bolt sheet is between blade cover and the lock body at lock core hole place, and described lock core positioning device is lock core spacer, the below of lock core spacer is provided with capping, and lock core spacer and capping be the below in lock core hole internal cylinder all; Lock core spacer is c-shaped, between two free ends of the lock core spacer of the bottom of lock bolt sheet in C shape; Lock core spacer is provided with the spacing plush copper being connected as a single entity with it, lock body is provided with the spacer draw-in groove that lock core spacer is installed, lock core spacer is fixed in spacer draw-in groove, and the capping of lock core spacer below seals lock core hole bottom, and the middle part of capping is provided with the key perforation of passing for key; Blade edge is provided with even number number breach, and the center of blade is provided with the keyhole passing for key, and number breach is along the upper and lower symmetric arrays in center of keyhole, and number breach along the left and right, center of keyhole also symmetric arrays.

As preferably, angle between two free ends of lock core spacer of C shape is 90 degree, it is the most convenient that lock core 90-degree rotation unblanks to produce, result of use is also best, the center of keyhole on the endoporus center of circle at lock core spacer middle part, blade, in the center of lock core hole and capping the center of key perforation all on same longitudinal straight line, the precision of product is high, and product quality is just high.

Adopted the unconfined lockset of key turns angle of technique scheme, adopt lock core spacer to substitute existing pin configuration, for lock core spacer, improved again the part-structure of lock body and added capping, produce assembling very convenient, with respect to also high with the safety of structure of employing pin.Blade edge is equipped with even number number breach, and number breach is along the upper and lower symmetric arrays in center of keyhole, and number breach along the left and right, center of keyhole also symmetric arrays simultaneously, assembling blade is to remember face, can put arbitrarily, the efficiency of processing is high.In sum, the advantage of the unconfined lockset of this key turns angle is novel structure, produce easy to assembly, safe, production efficiency is high.

The specific embodiment

Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the specific embodiment of the present utility model is made a detailed explanation.

The unconfined lockset of key turns angle as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises lock body 1 and interior lock core 2 and lock core positioning device thereof.Lock core 2 is arranged in the lock core hole in lock body 1, and lock core 2 comprises blade cover 6, blade 7 and lock bolt sheet 5, and blade 7 is arranged in blade cover 6, and lock bolt sheet 5 is between blade cover 6 and lock body 1 inside wall at lock core hole place.Blade 7 edges are provided with even number number breach 71, and the center of blade 7 is provided with the keyhole 72 passing for key, and number breach 71 is along the upper and lower symmetric arrays in keyhole 72 center, and number breach 71 is along left and right, keyhole 72 center also symmetric arrays.

Lock core positioning device is lock core spacer 3, and the below of lock core spacer 3 is provided with capping 4, and lock core spacer 3 and capping 4 be the below in lock core hole internal cylinder 2 all.Lock core spacer 3 cross sectional shapes are c-shaped, angle between two free ends of the lock core spacer 3 of C shape is 90 degree, between two free ends of the lock core spacer 3 of the bottom of lock bolt sheet 5 in C shape, and the endoporus center of circle at lock core spacer 3 middle parts is concentric with lock core hole, lock core 2 can only rotate within the scope of 90 degree between two free ends of the lock core spacer 3 of C shape.Lock core spacer 3 is provided with the spacing plush copper 31 being connected as a single entity with it, lock body 1 is provided with the spacer draw-in groove that lock core spacer is installed, lock core spacer 3 is fixed in spacer draw-in groove, the capping 4 of lock core spacer 3 belows seals lock core hole bottom, and the middle part of capping 4 is provided with the key perforation of passing for key.The center that on the endoporus center of circle at lock core spacer 3 middle parts, blade 7, in the center of keyhole 72 center, lock core hole and capping 4, key is bored a hole is all on same longitudinal straight line.

During use, key enters lock core 2 through the key perforation at capping 4 middle parts, after tartar is on the key corresponding with lock core 2 couplings, band movable lock core 2 rotates, the angle that lock core 2 rotates is not more than 90 degree and can only in the angle angular range between two free ends of the lock core spacer 3 of C shape, rotates, and is normally the switch that direct 90-degree rotation is realized lockset.When tartar on the key does not mate with lock core 2, in keyhole 72,360 degree angle is unconfined does not stop idle running on blade 7 for key, and lock core 2 does not turn, and lockset still cannot be opened.

The lockset of above-described embodiment is padlock, also comprises the structures such as U-shaped lock bridge, steel ball.
