Description

Anti-drilling, anti-poking and anti-prizing cylinder lock

The utility model relates to a kind of drilling and picking-resisting anti-prying cylinder lock that is applicable to that money box, door and other place of locking are used.

The tradition cylinder lock does not have the safety guard measure, and outer and core pellet shot from a slingshot dimerous hole is isometrical by lock in the structure of its lock, once key hole is axially drilled through, the pellet shot from a slingshot in the hole will drop out under the effect of spring, is directed at the out of control of this lock.

The purpose of this utility model is, the criminal of preventing and self-protection mechanism is set locking, and designs a kind of cylinder lock of drilling and picking-resisting pick-proof, with the safety of protection family and national wealth.

In order to achieve the above object, the design scheme of drilling and picking-resisting anti-prying cylinder lock of the present utility model is, the pellet shot from a slingshot hole that will be drilled with on lock skin and core two parts is designed to the circular hole of two sections different-diameters, and the bore dia difference can be located at respectively on the certain position in lock outer pellet shot from a slingshot hole and core pellet shot from a slingshot hole according to anti-drilling, the anti-group function of pellet shot from a slingshot; According to the structure in pellet shot from a slingshot hole, the pellet shot from a slingshot in the hole is designed to be made up of column type pellet shot from a slingshot and T type cylindrical billiard two parts; Near in the pellet shot from a slingshot hole of key hole one end and pellet shot from a slingshot joint portion and core afterbody between lock skin and the lock core all set up anti-drilling steel ball.

For structure and principle to drilling and picking-resisting anti-prying cylinder lock of the present utility model have further understanding, as follows in conjunction with a specific embodiment enumeration in the utility model:

Accompanying drawing 1 is the sectional structure schematic diagram of present embodiment drilling and picking-resisting anti-prying cylinder lock.

Accompanying drawing 2 is the right view of accompanying drawing 1.

Accompanying drawing 3 is the pick-proof structural representation of drilling and picking-resisting anti-prying cylinder lock.

Accompanying drawing 4 is the right view of accompanying drawing 3.

As shown in the figure, the structure of the drilling and picking-resisting anti-prying cylinder lock of present embodiment is, on key hole ［ 11 ］ top lock outer ［ 1 ］ and core ［ 2 ］ radially be drilled with 6 pellet shot from a slingshot holes ［ 3 ］［ 4 ］［ 5 ］［ 6 ］［ 7 ］［ 8 ］, pellet shot from a slingshot hole ［ 3 ］［ 4 ］［ 5 ］［ 6 ］［ 7 ］ all is the circular hole that two sections diameters differ 1.00mm, the pellet shot from a slingshot that is provided with in these holes ［ 12 ］［ 13 ］［ 14 ］［ 15 ］［ 16 ］ also is respectively to be made of column type pellet shot from a slingshot and T type cylindrical billiard two parts, wherein the T type cylindrical billiard of pellet shot from a slingshot ［ 12 ］ and ［ 16 ］ is established with core shell hole one end, cylindrical billiard is located at outer shell hole one end of lock, owing to aiming at anti-dialling, pellet shot from a slingshot ［ 12 ］［ 16 ］ designs, so it is all longer than the pellet shot from a slingshot in other lock outer hole, the T type cylindrical billiard of pellet shot from a slingshot ［ 13 ］［ 14 ］［ 15 ］ is at the outer shell hole end of lock, cylindrical billiard is at core shell hole one end, and it is anti-drilling design like this; Pellet shot from a slingshot hole ［ 8 ］ is an isometrical circular hole, in its hole, be provided with three anti-drilling steel balls ［ 10 ］, under normal circumstances, steel ball ［ 10 ］ but bump pearl usefulness between double as lock outer ［ 1 ］ and the core ［ 2 ］, the spring in the pellet shot from a slingshot hole ［ 9 ］ withstands on each pellet shot from a slingshot and the steel ball ［ 10 ］; In order to protect lock body, in core ［ 2 ］ afterbody midline, promptly in the circular hole that dead bolt control connection bar ［ 18 ］ and jump ring ［ 19 ］ front end are drilled with, establish a steel ball ［ 17 ］; In the both sides screw ［ 20 ］ that tapered end is connected with lock body, respectively be provided with steel ball ［ 21 ］.

The principle of the drilling and picking-resisting pick-proof of this lock is:

Outer ［ 1 ］ internal cause of lock has three steel balls ［ 10 ］ to stop that drill bit can't pierce, even pierce by force, invar pearl hardness is very big, also can force drill bit to change direction, thereby has also just protected the pellet shot from a slingshot of lock outer hole part.

When drill bit by key hole ［ 11 ］ when inwardly boring, all pellets shot from a slingshot pellet shot from a slingshot hole of under the pressure of drill bit, can thereupon withdrawing, but the anti-pellet shot from a slingshot of dialling the lock core hole of pellet shot from a slingshot ［ 12 ］［ 16 ］ can part damage, after drill bit is extracted out, the pellet shot from a slingshot of the lock core hole part in anti-drilling pellet shot from a slingshot hole ［ 4 ］［ 5 ］［ 6 ］ comes off, the pellet shot from a slingshot of the lock outer hole of ［ 13 ］［ 14 ］［ 15 ］ part can fall under the effect of spring ［ 9 ］ thereupon simultaneously, enter in the lock core hole, the anti-pellet shot from a slingshot ［ 12 ］［ 16 ］ of dialling is except that the slight damage of lock core hole pellet shot from a slingshot part, and all recover lock function again.Because the outer pellet shot from a slingshot of the lock of pellet shot from a slingshot ［ 12 ］［ 16 ］ is all longer than other pellet shot from a slingshot, remaining like this core pellet shot from a slingshot partly adds the outer pellet shot from a slingshot part of long lock, add the spring length after maximum pressure contracts, their total length will inject in the core shell hole above the length of the outer shell hole of lock.Two anti-group pellets shot from a slingshot ［ 12 ］［ 16 ］ are as long as one works, and the outer pellet shot from a slingshot part of the lock of ［ 13 ］［ 14 ］［ 15 ］ just can be controlled core.

Drill bit axially pierces from key hole ［ 11 ］, and lock body protection steel ball ［ 17 ］ shelves that will be headed on are lived, and it directly pushes lock body aside with screwdriver after having prevented that drill bit from destroying the shared jump ring ［ 19 ］ of dead bolt control connection bar ［ 18 ］ and core tail end again.As piercing by force, steel ball can force drill bit to change direction, departs from the lock body control hole, thereby reaches the purpose of protection lock body.

As shown in Figure 3; in order to prevent that drill bit from directly boring the fixing threaded hole ［ 20 ］ of unblanking between body and the tapered end from the front; after under the whole sled of tapered end; directly push lock body aside; the steel ball ［ 21 ］ that is provided with in screw ［ 20 ］ forces drill bit to change direction; the safety of fixing threaded hole between protection lock body and the tapered end is to reach the pick-proof purpose.

Drilling and picking-resisting anti-prying cylinder lock of the present utility model is simple in structure, handling ease, cost is low, it is compared with traditional cylinder lock, only increasing several steel balls and changing cleverly under the feelings condition of pellet shot from a slingshot hole and billiards structure, just play anti-drilling, anti-ly dial, the various functions of pick-proof, the structure of this lock is the ideal design of cylinder lock, it can be supporting with various lock bodies, is installed on various doors and the money box.
