Description

Automatic hidden lockhole anti-theft unlocking head and key

Technical field

The utility model relates to a kind of lockset, relates in particular to the lock of a kind of automatic hidden lockhole anti-theft unlocking head and key.

Background technology

The basic function of existing lock is antitheft, the anti-theft feature power is that mainly tapered end adds key, various mechanical lock heads in the market all are that the pellet shot from a slingshot in the tapered end is misplaced and resets, to reach the purpose performance of opening and closing, its defective is, tapered end exposes, pellet shot from a slingshot exposes, key is bigger than normal, is easily opened with foreign matter.

Summary of the invention

Order of the present utility model just is to provide anti-hard thing contact tapered end of a kind of automatic hidden lockhole and key, accomplishes the advantage of anti-theft feature height, simple in structure, easy making.

The technical solution of the utility model comprises: lock core is hidden in the outer lock core; lock core has the ￠ shape key hole of ￠ shape key hole and outer lock core to communicate with the external world; tapered end has the shell hole of two groups of symmetries; every row's shell hole has the pellet shot from a slingshot hole more than four; there is the key of ￠ shape in lock core central authorities; flute profile is " ￠ " font; outer lock core is provided with the lockhole screening glass with the place of communicating, the external world; the two ends of corresponding lockhole screening glass are provided with locking device, and the recessed lockhole that is provided with on the key that internal cylinder matches is protected reseting groove and fork-shaped tooth.

Described locking device is made of locking plate pellet shot from a slingshot, locking plate, lockhole screening glass and locking plate spring, and the locking plate spring is fixed in the outer lock core, and locking plate is fixed on the internal cylinder, is provided with the locking plate pellet shot from a slingshot between locking plate and the locking plate spring.

Compared with prior art, advantage of the present utility model is,

1, it is strong especially, simple in structure to the utlity model has anti-pirate of the open function, be easy to the characteristics of processing and manufacturing, its material, making are identical with the existing machinery tapered end basically with mounting process, using method etc., and anti-theft feature has but improved greatly, is desirable existing machinery tapered end regeneration product.

2, because of this tapered end has concealed type, and the key of coupling is difficult for by the existence of the low all advantages of mutual opening rate of imitated, key, makes this tapered end and key thereof, has insurance anti-theft feature height, advantage that security reliability is strong.

The specific embodiment

Embodiment; as Fig. 1; Fig. 2; Fig. 3; Fig. 4 and shown in Figure 5; internal cylinder 3 is hidden in the outer lock core 2; internal cylinder 3 is provided with the ￠ shape key hole that ￠ shape key hole and outer lock core 2 be provided with and communicates with the external world; be provided with the shell hole 4 of two groups of symmetries in the internal cylinder 3; every row's shell hole has the pellet shot from a slingshot hole more than four; there is the key 1 of ￠ shape in internal cylinder 3 central authorities; flute profile is " ￠ " font; outer lock core 2 is provided with lockhole screening glass 8 with the place of communicating, the external world; the two ends of corresponding lockhole screening glass 8 are provided with locking device 5, and the key 10 that internal cylinder 3 matches is provided with recessed lockhole protection reseting groove and fork-shaped tooth 11.

Described locking device 5 is made of locking plate pellet shot from a slingshot 6, locking plate 7, lockhole screening glass 8 and locking plate spring 9, and locking plate spring 9 is fixed in the outer lock core 2, and locking plate 7 is fixed on the internal cylinder 3, is provided with locking plate pellet shot from a slingshot 6 between locking plate 7 and the locking plate spring 9.

Key 10 is inserted in the key 1, hold because of key 10 heads have 45 degree shape angles, garden can squeeze lockhole screening glass 8 automatically, when corresponding with pellet shot from a slingshot, lockhole screening glass 8 automatically resets, and makes to lock to be in opening when key 10 is inserted into lock core 3 in; When taking out key 10, there are 45 degree shape angles, garden reseting groove internal cause key 10 ends, can push lockhole automatically open, take out key, and lockhole screening glass 8 automatically resets.
