Description
Technical field
The utility model relates to the lock class, particularly a kind of cylinder lock head with anti-group function.
Background technology
Cylinder lock is simple in structure with it since coming out, and manufacturing and the reasonable advantage of theftproof performance are used widely easily.No matter be door lock, the lock that drawer-lock or furniture use nearly all is a cylinder lock at present.Yet in recent years, the higher robber of some IQ used a kind of special pearl instrument of dialling under the situation of key lock to be opened not having, and made the theftproof performance of cylinder lock be subjected to very big impact.In recent years, though there are some producers to develop the higher cylinder lock of some theftproof performances, because of complex structure, manufacturing cost height are difficult to apply.
Summary of the invention
In order to solve the anti-problem of dialling of existing cylinder lock, the utility model provides a kind of anti-cylinder lock head of dialling function that has.This cylinder lock has the good anti-lock performance of pushing aside.
Above-mentioned task realizes by this way: a kind of cylinder lock head with anti-group function, include lock core shell, lock core, bead sealing piece and several are by spring, the pellet shot from a slingshot group that the flat pearl and the decorative pearl on top of an official cap are formed, it is characterized in that: be provided with a slice pellet shot from a slingshot partition at least at the lock core at pellet shot from a slingshot group place and the both sides of the lock core shell surfaces of revolution, this pellet shot from a slingshot partition is arranged on the lock core, and on lock core, have a up and down pit of pellet shot from a slingshot partition that cooperates with the pellet shot from a slingshot partition, the top of the described decorative pearl on top of an official cap is provided with the diameter termination directly littler than pearl, on the pellet shot from a slingshot partition, have and each pellet shot from a slingshot group decorative pearl on top of an official cap termination through hole movingly, the thickness of pellet shot from a slingshot partition equates with decorative pearl on top of an official cap termination height, described flat pearl is made of interior flat pearl and outer flat pearl, also be provided with the termination that cooperates with the pellet shot from a slingshot partition in interior flat pearl lower end, described spring is made up of interior flat pearl spring and outer flat pearl spring.
Description of drawings
The purpose of this utility model can also take following measure further perfect:
The thickness of described pellet partition is take 0.5～1.3 millimeter as suitable.
The degree of depth of the up and down pit of described pellet partition with the thickness of 1.3～2 pellet partitions for well.
On lock core shell, also be provided with a slice pellet shot from a slingshot partition identical, on lock core shell, have the pit that cooperates with this pellet shot from a slingshot partition with the pellet shot from a slingshot partition of lock core.
After above-mentioned improvement, the unlocking condition of this tapered end is the same with existing cylinder lock, and after key inserted lock core, the end face of the decorative pearl on top of an official cap and pellet shot from a slingshot partition and the bottom surface of flat pearl all were on the surfaces of revolution of lock core and lock core shell, lock core is unfettered, and the just rotatable lock core of key is opened lock.But after key is transferred to, its blocking and existing tapered end are just different, when each decorative pearl on top of an official cap drops to the key bottom surface, the pellet shot from a slingshot partition also drops to the bottom of the up and down pit of pellet shot from a slingshot partition thereupon, place in the lock core, the surfaces of revolution that each flat pearl is also crossed lock core and lock core shell drops on the pellet shot from a slingshot partition of lock core lock core is blocked, and lock core can not rotate, thereby will pin.When the robber dials pearl when unblanking with dialling the pearl instrument by gimmick commonly used, because each decorative pearl on top of an official cap is isolated by the pellet shot from a slingshot partition, do not contact and movable state about being in flat pearl, wanting to find a decorative pearl on top of an official cap that relatively presses is the comparison difficulty.Even find one because of lock core rotates the flat pearl of being pressed tightlyer by the decorative pearl on top of an official cap, when up provoking this decorative pearl on top of an official cap then, the pellet shot from a slingshot partition also rises thereupon, when the surfaces of revolution till.This moment, flat pearl bottom also was on the surfaces of revolution, under the effect of lock core rotational pressure, flat pearl might be toward direction of rotation skew and can not be over against the through hole of pellet shot from a slingshot partition, but when the robber puts down this decorative pearl on top of an official cap and chooses second decorative pearl on top of an official cap again, the pellet shot from a slingshot partition just can fall, the interior flat pearl of this flat pearl also can fall and falls under spring action with the pellet shot from a slingshot partition, thereby lock core is blocked.In addition, owing between interior flat pearl of flat pearl and the outer flat pearl certain activity fit tolerance is arranged.And between the through hole of the termination of interior flat pearl bottom and pellet shot from a slingshot partition certain activity fit tolerance is arranged, therefore, outer flat pearl is subjected to that rotation pressure produces mobile be not enough to allow in flat pearl bottom head depart from too much, the elastic force effect of flat within it pearl spring might be inserted in the through hole of pellet shot from a slingshot partition down very soon, get back to reset condition, lock core is blocked, this shows, it is very difficult going to unblank by common method with group pearl instrument.In addition, when wherein a decorative pearl on top of an official cap was with pellet shot from a slingshot partition jack-up, its active force can not be at the center of pellet shot from a slingshot partition, the pellet shot from a slingshot partition can not level rise, Yi Bian perk a little must be arranged, is difficult to be on the same level with the surfaces of revolution, also blocked lock core, lock core can not be rotated.Therefore, have only key inserted in the keyhole, each decorative pearl on top of an official cap simultaneously with the holder of pellet shot from a slingshot partition level to the surfaces of revolution between lock core and the lock core, when the bottom of each flat pearl also is on the surfaces of revolution, make that lock core is unfettered could be opened lock.If in the flat pearl bottom of lock core shell a slice pellet shot from a slingshot partition is set also, when locking, this pellet shot from a slingshot partition also can be fallen this in-core, and the robber more difficultly finds suitable flat pearl to dial pearl by the decorative pearl on top of an official cap when dialling pearl, thereby has further strengthened the difficulty of group pearl.The utility model is dialled pearl through experienced lockmaking technician and is unblanked, and all lock can't be opened in the five-minute period of industry regulation.Therefore, the utlity model has the good anti-performance of dialling, solved the anti-problem of pushing the lock poor performance aside of existing cylinder lock effectively.
