Description
Technical field
The utility model relates to a kind of mechanical lock, particularly relates to a kind of idle running anti-prizing type lock.
Background technology
Traditional tapered end uses some simple tools to open, for strengthening tamper-resistant function, also there has been the rotation tapered end of pick-proof in market, as Chinese patent, the patent No.: 200710035991.7, the lock core structure of this structure can be done 360 degree idle running by the relative lock body of lock core when non-lock key or the insertion of other instrument, can effectively prevent skilled unlocking and picking lock, but this lock construction more complicated, manufacture craft is loaded down with trivial details.
Summary of the invention
The purpose of this utility model just provides a kind of simple for structure, is convenient to make, and uses more reliable and more stable idle running anti-prizing type lock.
For achieving the above object, the utility model adopts following technical scheme:
A kind of idle running anti-prizing type lock, comprise: lock core, lock core base, pellet shot from a slingshot, the pellet shot from a slingshot spring, the tail bar, it is characterized in that being provided with in the lock core slide block slot, be provided with slide block in the slide block slot, the position that pellet shot from a slingshot passes in the slide block is provided with porose, pellet shot from a slingshot is respectively arranged with groove towards a side of tail bar, one side of the corresponding pellet shot from a slingshot groove in the hole of slide block can and can pass in and out the pellet shot from a slingshot groove along slip before and after the locking plate groove, the tail end of lock core is provided with tailing axle, and a side of the corresponding slide block of tailing axle is provided with the locking film trap, is provided with locking plate in the locking film trap, locking plate can slide before and after the locking film trap, and can pass in and out slide block slot, axially being provided with of tailing axle is porose, is provided with the spring to locking plate thrust in its hole.
Described pellet shot from a slingshot axially corresponding both sides can be set to the plane.
The notch downside of described pellet shot from a slingshot groove is the inclined-plane.
One side of the corresponding pellet shot from a slingshot groove in the hole of described slide block can be set to inclined-plane or chamfering, upper side is the plane.
Described pellet shot from a slingshot can be set to single or double, and each pellet shot from a slingshot top is provided with spring.
The afterbody of described tapered end seat is provided with eccentric grove.
The operating principle of this tapered end: when key inserted lock core, the pellet shot from a slingshot lower end in the lock core was corresponding with the tartar of key, and each pellet shot from a slingshot groove and slide block are at same axis and produce enough gaps.Break away from locking plate the eccentric stern notch of tapered end and insert the lock core groove connection this moment under the active force of tailing axle locking plate spring; Simultaneously the slide block displacement is coincide.The twisting key cylinder drives tailing axle and rotates, and lock is unlocked.After key is extracted, the pellet shot from a slingshot in the lock core when key is extracted active force and the active force of marble spring under slide block is resetted, and locking plate is broken away from lock core, enter the eccentric stern notch engaging of tailing axle and tapered end, tailing axle can not rotate, lock is closed.Non-original key inserts lock core, and tartar on the key is not corresponding with pellet shot from a slingshot, and the groove of pellet shot from a slingshot and the hole of slide block can not match, and slide block is motionless, and tailing axle is not connected with lock core.360 ° of idle running of lock core, lock can not be opened.
Superiority of the present utility model is that structure is more reasonable, and is simple for structure, is convenient to processing and fabricating, and stability is higher; Because non-key or instrument are opened Lock cylinder idling, effectively pick-proof and by TO locksets such as hand commentaries on classics is safe and reliable.

Specific embodiment
Referring to figs. 1 through this as can be seen idle running anti-prizing type lock of Fig. 5, comprise: lock core 5, lock core base 10, pellet shot from a slingshot 4, pellet shot from a slingshot spring 3, tail bar 14, be provided with slide block slot 21 in the described lock core 5, be provided with slide block 2 in the slide block slot, the place that pellet shot from a slingshot passes in the slide block is provided with porose 22 (with reference to Fig. 9), this hole can be a slot, each pellet shot from a slingshot is respectively arranged with groove 23 (with reference to Figure 11) towards a side of tail bar 14, the side that this groove is used for slider bore 22 corresponding pellets shot from a slingshot can and can pass in and out pellet shot from a slingshot groove 23 along slip before and after the locking plate groove, the tail end of lock core is provided with tailing axle 13, one side of the corresponding slide block of tailing axle is provided with locking film trap 18, be provided with locking plate 1 in the locking film trap, locking plate can slide before and after the locking film trap, and can pass in and out slide block slot 21, axially being provided with of tailing axle is porose 19, is provided with the spring 20 to locking plate thrust in its hole.When key 7 inserts lock core 5, pellet shot from a slingshot 4 lower ends in the lock core are corresponding with the tartar of key, each pellet shot from a slingshot groove 23 and slide block 2 are at same axis and produce enough gaps, make under the active force of the locking plate spring 20 in the tailing axle, locking plate 1 is broken away from the eccentric stern notch 15 of tapered end and inserts 21 connections of lock core slide block slot; Simultaneously slide block 2 displacements are coincide.The twisting key cylinder drives tailing axle and rotates, and lock is unlocked.
With reference to Fig. 6, Fig. 7, Fig. 8 as can be seen: after key 7 is extracted, under the active force (with reference to Fig. 1) on pellet shot from a slingshot 4 key bit inclined-plane 11 when key is extracted that lock core is 5 li and the active force of marble spring 3 slide block 2 is resetted, and with locking plate 1 disengaging lock core 5, enter eccentric stern notch 15 engagings of tailing axle and tapered end, tailing axle 14 can not rotate, and lock is closed.Non-original key inserts lock core, and tartar on the key is not corresponding with pellet shot from a slingshot, and the groove of pellet shot from a slingshot and the hole of slide block can not match, and slide block is motionless, and tailing axle is not connected with lock core.360 ° of idle running of lock core, lock can not be opened.
Pellet shot from a slingshot axially corresponding both sides 25,26 (Figure 12) can be set to the plane, purpose is to prevent that pellet shot from a slingshot from rotating, to keep pellet shot from a slingshot groove direction unanimity.The notch downside of pellet shot from a slingshot groove is inclined-plane 23 (Figure 11), is convenient to pellet shot from a slingshot and promotes moving of slide block disengaging pellet shot from a slingshot groove under the active force of key.One side of the corresponding pellet shot from a slingshot groove in the hole 22 of slide block (Fig. 9, Figure 10) can be set to inclined-plane 24 or chamfering.Pellet shot from a slingshot can be set to single or double, and double pellet shot from a slingshot more helps pick-proof, and key is difficult for repeating.
