Abstract

The utility model relates to an anti-theft lock with a pin tumbler lock core and a key, which comprises a lock core and a lock body. The strip-shaped pinholes are arranged lengthways at one side or two sides of the lock core. A variable diameter is provided for the strip-shaped pinhole near the end of the lock core hole. The lock body opens a pinhole corresponding to the strip-shaped pinhole. The pin is arranged in the hole and a spring is arranged on the top of the pin. The key is used as a set with the anti-theft lock with the pin tumbler lock core and the main body of the key is a solid round shaft. A plurality of top teeth corresponding to the strip-shaped pinhole of the lock cores are arranged in axial direction and the top teeth are arranged lengthways at one side or two sides of the main body of the key. A slope of 45 degrees is formed at the end of the tooth towards the rotary direction of releasing the lock. The pinhole of the lock core of the anti-theft lock reduces the diameter at the end of the pin core hole, which limits the pin in the corresponding strip-shaped pinhole at both sides of the lock core. The pin can't be seen through the hole of the key whenever the lock is locked or released. Even if the lock is pried with a tool, the pin can't be touched by the prying tool, so the lock can't be released, which enhances the anti-theft performance of the pin tumbler lock.

Description

A kind of theftproof lock of lock cylinder and key thereof

One, technical field:

The utility model belongs to lockset, specifically is a kind of theftproof lock and key of lock cylinder.

Two, background technology:

Lock is to be used to guarantee safe important apparatus in the daily life, and at present, the kind of lockset is a lot, and lock cylinder lockset wherein uses also very general.The lockset of this lock cylinder can be seen pellet shot from a slingshot in the lock core from keyhole, as long as instrument can inject lockhole and stir pellet shot from a slingshot gently, just lock can be opened, so the security performance of this lock is relatively poor.

Three, summary of the invention:

The purpose of this utility model is theftproof lock and the key that a kind of lock cylinder is provided at the problems referred to above, and this lockset be can't see pellet shot from a slingshot from keyhole, the problem that its pellet shot from a slingshot of lockset of solution lock cylinder is easily pushed aside, the theftproof of raising lock cylinder lockset.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of theftproof lock of lock cylinder comprises lock core and lock body, the one or both sides of lock core vertically are arranged with bar shaped pellet shot from a slingshot hole, there is being reducing in bar shaped pellet shot from a slingshot hole near the lock core nose end, the corresponding bar shaped pellet shot from a slingshot of lock body hole has the pellet shot from a slingshot hole, pellet shot from a slingshot, pellet shot from a slingshot top shock mount are installed in the hole.

With the matching used key of the theftproof lock of lock cylinder, the key main body is solid circular shaft, the corresponding apical tooth in bar shaped pellet shot from a slingshot hole with lock core is axially arranged, and apical tooth is vertically arranged in key main body one or both sides, and there are the gradients of 45 degree the end of apical tooth to the rotation direction of unblanking.

The beneficial effects of the utility model are:

The pellet shot from a slingshot hole of lock core is at lock core nose end undergauge in the utility model, pellet shot from a slingshot is limited in the bar shaped pellet shot from a slingshot hole of lock core both sides correspondence, be locked in locking or open mode and all can't see pellet shot from a slingshot from keyhole, even stir with instrument, prize the tool of exchanging work and do not reach pellet shot from a slingshot, lock can't be opened, improve the theftproof performance of cylinder lock.

Fig. 2 is the structural representation of locking in the utility model;

Fig. 3 is the structural representation of lock core in the utility model;

Fig. 4 is the structural representation of lock body in the utility model;

Fig. 5 is an A-A sectional drawing among Fig. 1;

Fig. 6 is the structural representation of the utility model key.

Among the figure: 5 pellets shot from a slingshot, 6 springs, 7 apical tooths of 1 lock core, 2 lock bodies, 3 lock core holes, 4 bar shaped pellet shot from a slingshot holes

Five, the specific embodiment: in conjunction with the accompanying drawings the utility model is described further.

Fig. 1 is an overall structure schematic diagram of the present utility model, provides the overall structure of the theftproof lock and the key of lock cylinder, is the opening of lockset.Fig. 2 is the structural representation of locking in the utility model, according to shown in Figure 2, the theftproof lock of lock cylinder comprises lock core and lock body, and lock core 1 has bar shaped pellet shot from a slingshot hole 4, bar shaped pellet shot from a slingshot hole 4 can vertically be arranged in a side of lock core 1, also can be in the vertically corresponding arrangement in the both sides of lock core 1.When vertically arranged in the both sides of lock core 1 correspondence in bar shaped pellet shot from a slingshot hole 4, bar shaped pellet shot from a slingshot hole 4 its center lines of both sides correspondence are laterally staggered to be cross, and the structure of lock core 1 is consulted Fig. 3, and the structure of lock body 2 is consulted Fig. 4, and Fig. 5 is an A-A sectional drawing among Fig. 1.Shown in Fig. 3,4,5, the quantity that vertically is provided with in bar shaped pellet shot from a slingshot hole 4 is at least two.Bar shaped pellet shot from a slingshot hole 4 vertically is arranged as six in the both sides of lock core 1 among the embodiment that the utility model provides, six bar shaped pellet shot from a slingshot hole 4 corresponding staggered vertically arrangements in the both sides of lock core, each bar shaped pellet shot from a slingshot hole is at close lock core hole 3 end reducings, the diameter at reducing place is less than the diameter of pellet shot from a slingshot 5, vertically its length of reducer between the bar shaped pellet shot from a slingshot hole 4 of arranging is crisscross arranged, limit the scope of activities of pellet shot from a slingshot 5 in bar shaped pellet shot from a slingshot hole 4 by reducing and spring, reducing place to lockhole is maintained a certain distance.Lock body 2 corresponding bar shaped pellet shot from a slingshot holes 4 have the pellet shot from a slingshot hole, and pellet shot from a slingshot 5, pellet shot from a slingshot 5 top shock mounts 6 are installed in the hole.When spring 6 peaks at the junction of lock core 1 and lock body 2 with a pellet shot from a slingshot, when making lockset be in locking state, another pellet shot from a slingshot then withstands on reducing mouth place.Owing to from reducing mouth to lock core hole reducer is arranged, the diameter of reducer makes pellet shot from a slingshot can not enter reducer again less than the diameter of pellet shot from a slingshot, therefore, is that keyhole be can't see pellet shot from a slingshot 5 from the bottom of lock core hole 3, also is difficult to judge the length distance of each reducer.

Fig. 6 is the structural representation of the utility model key, with the matching used key main body of the theftproof lock of lock cylinder be real core circular shaft, the bar shaped pellet shot from a slingshot hole 4 corresponding apical tooths 7 with lock core 1 are axially arranged, apical tooth 7 is vertically arranged in the one or both sides of lock core shaft.When apical tooth 7 is vertically arranged in the both sides of lock core shaft, the laterally staggered cross that is of apical tooth 7 its center lines of both sides correspondence, the length of each apical tooth 7 is corresponding with the reducer in bar shaped pellet shot from a slingshot hole, lock core 1 both sides 4, the length of apical tooth 7 is crisscross arranged vertical the arrangement, and there are the gradients of 45 degree the end of apical tooth 7 to the rotation direction of unblanking.

When opening lock, when key insertion lock core hole 3, the apical tooth 7 of key is corresponding with the bar shaped pellet shot from a slingshot hole 4 of lock core 1, rotation to the left or to the right, and apical tooth 7 pushes pellet shot from a slingshot 5, and lockset is opened.
