Abstract

The utility model relates to a burglarproof lock core with biasing marbles and a key, which is mainly characterized in that biasing outer marble holes are distributed on the circumferential wall of an outer cover of a lock core, inner marble holes which are communicated with a key hole are arranged on the positions on the circumferential wall of an inner core, which are corresponding to the outer marble holes, the axial center position of the inner core is provided with a key guiding rib, and the section of a key which is matched with the lock core is S-shaped. The lock core can effectively prevent the illegal unlocking by various technical tools, the mutually unlocking rate of the key of the lock core is low and the utility model has the advantages of safe use, simple manufacture, low manufacturing cost and the like, and the lock core and the key can be matched and used with various lock bodies.

Description

Biasing anti-theft cylinder lock core and key

Technical field

The utility model belongs to lock technology field, is specially adapted to supporting biasing anti-theft cylinder lock core and the keys of general lock body such as door lock and lock.

Background technology

In technique known, lockset commonly used mostly is a cylinder lock, and the pellet shot from a slingshot hole of the lock core of cylinder lock mostly is radially setting, and not only key is prepared easily, even dials the twist lock inner core with a slice substance, can unblank, and theftproof performance is poor.At present, disclosed various locks on the market in the improvement that all has aspect pellet shot from a slingshot arrangement and the Key structure in various degree, have plenty of at the teeth and the gathering sill position of key and take some structural measures, but still have the mutual opening rate height and copy easier defective.Also has plenty of the multiform shape of key body being made three tooth punchings, though anti-theft effect improves to some extent complex manufacturing technology.Along with the development of social science and technology, the high iq crime constantly increases, and the theft technology is also more ingenious, and therefore, it is very necessary to research and develop novel anti-theft lock.

The utility model content

The purpose of this utility model provides and a kind ofly can improve the lockset theftproof performance, and mutual opening rate is low, and can effectively avoid biasing anti-theft cylinder lock core and the key copied.

Realize that the technical scheme that the purpose of this utility model is taked is: the outer pellet shot from a slingshot hole that is laid with biasing on the circumferential wall of lock core sleeve, be provided with the interior pellet shot from a slingshot hole that is communicated with keyhole with the circumferential wall of its correspondence position inner core, the axis part of inner core is provided with key guiding rib, with the cross section of the supporting key of lock core be S shape.

The outer pellet shot from a slingshot of cylindricality, return spring and shutoff wherein, are equipped with more than at least 6 pairs in described inside and outside pellet shot from a slingshot hole in the outer pellet shot from a slingshot hole, pellet shot from a slingshot in the cylindricality is housed in the interior pellet shot from a slingshot hole.

Described inside and outside pellet shot from a slingshot hole can singlely be laid, and also can adopt symmetry or asymmetric double to arrange and establish.

Biasing anti-theft cylinder lock core and the key made according to such scheme, adopt the biasing billiards structure, can prevent the pirate of the open of various technical tools effectively, its key mutual opening rate is low, and have advantages such as safe in utilization, simple for production, that cost is low, can with the supporting use of multiple lock body.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional view of A-A among Fig. 1;

Fig. 3 is the Key structure schematic diagram supporting with lock core;

Fig. 4 is the sectional view of B-B among Fig. 3.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, biasing anti-theft cylinder lock core of the present utility model and key comprise overcoat 1, inner core 2, shutoff 3, return spring 4, outer pellet shot from a slingshot hole 5, interior pellet shot from a slingshot 6, key guiding rib 7, location finger 8, outer pellet shot from a slingshot 9, keyhole 10, interior pellet shot from a slingshot hole 11, key 12, and each member is formed a whole lock core.Wherein, outer pellet shot from a slingshot hole 5 is laid on the circumferential wall of lock core sleeve 1 in the mode of tangential setting, and the circumference of overcoat 1 can outwards be given prominence to the corresponding position in outer pellet shot from a slingshot hole 5, to increase the intensity of overcoat 1.The sum in outer pellet shot from a slingshot hole 5 is at least more than 6, and single or double symmetry or asymmetric axially-aligned arrange, by the biasing in a plurality of pellets shot from a slingshot hole, can reach and prevents the technical tool pirate of the open, reduces the purpose of key 12 mutual opening rates.The outer pellet shot from a slingshot 9 of cylindricality, return spring 4 and shutoff 3 are housed in the outer pellet shot from a slingshot hole 5 successively.Interior pellet shot from a slingshot hole 11 is located on the circumferential wall of inner core 2, and is corresponding with outer pellet shot from a slingshot hole 5, and is communicated with keyhole 10, and pellet shot from a slingshot 6 in the cylindricality is housed in the hole.The axis part of inner core 2 is provided with key guiding rib 7, with the gathering sill corresponding matching on the key 12.Label 8 is the location fingers that cooperate with lock body.With the cross section of the supporting key 12 of lock core be S shape, with keyhole 10 corresponding matching on the lock core, its teeth of unblanking are arranged on the sidepiece of key body, and single teeth can be set, and also double teeth can be set, so that the mutual opening rate of key 12 is reduced greatly.

Claims

1, a kind of biasing anti-theft cylinder lock core and key, it is characterized in that: the outer pellet shot from a slingshot hole that on the circumferential wall of lock core sleeve, is laid with biasing, be provided with the interior pellet shot from a slingshot hole that is communicated with keyhole with the circumferential wall of its correspondence position inner core, the axis part of inner core is provided with key guiding rib, with the cross section of the supporting key of lock core be S shape.

2, biasing anti-theft cylinder lock core according to claim 1 and key is characterized in that: the outer pellet shot from a slingshot of cylindricality, return spring and shutoff wherein, are equipped with more than at least 6 pairs in described inside and outside pellet shot from a slingshot hole in the outer pellet shot from a slingshot hole, pellet shot from a slingshot in the cylindricality is housed in the interior pellet shot from a slingshot hole.
