Abstract

The invention relates to an isolated antitheft lock. Compared with the common locks, the greatest difference of the isolated antitheft lock is that a key is not in direct contact with pins in the lock when the key is inserted into a key hole, while the key is in contact with the pins only after the key is turned to a certain angle. Since the pins of the lock and the key hole are isolated from each other through a lock body and a cylindrical body in a lock cylinder, the pins are very difficult to hook to move by using a foreign object; since the lock cylinder is internally sheathed in the lock body, the lock cylinder is very difficult to turn by using the foreign object; and by using the key to the isolated antitheft lock, a narrow connecting handle in an opening area can pass through a gap in the lock to reach a pin area very conveniently and the lock can be unlocked very easily and smoothly. The lock body can be manufactured to be very firm, the performance of the lock body is not influenced and the isolated antitheft lock provided by the invention is a very firm lock which is very difficult to unlock.

Description

Isolated anti-theft lock end

Technical field

The present invention relates to a kind of anti-theft lock end, be specifically related to the segregate anti-theft lock end of a kind of pellet shot from a slingshot district and key hole.

Background technology

The anti-theft lock end of conventional art comprises housing, lock core, pellet shot from a slingshot, and lock core is installed in the lock body in hole, band garden; The lock core rotating shaft exposes, and pellet shot from a slingshot can be got a glimpse of, when original key inserts key hole; The pellet shot from a slingshot playback, lock core can rotate, and is able to open; But insert when rotating in lockhole with non-its original key, though can not rotating opening, its rotating shaft can toward about, up and down can trace mobile; Rotate 360 degree though the lock core that has also can be followed, using force, by force under the situation of sled and special tool, often all can be damaged very soon; Particularly use some professional tools of skilled unlocking, as with hook, take the photograph son, opener, vibratory equipment even a mouthful balosam can both open it easily, and do not destroy lock.Why skilled unlocking can reach is not at present had the stage of locking not open, and reason is the structural defective because of traditional locks, and the lock core rotating shaft exposes, and pellet shot from a slingshot is smooth visible, and can directly touch.The means that skilled unlocking often uses are earlier with suitable power fixed lock core rotating shaft, to use hook to stir each pellet shot from a slingshot then; Come individual each to break up, just open traditional lock easily, also have professional tool in addition; Like vibratory equipment, need not stir, and need not contact pellet shot from a slingshot each pellet shot from a slingshot; Make a pellet shot from a slingshot group move, can very apace lock be opened.These locks do not have good antitheft effect basically.

Summary of the invention

For solving these problems that exist in the prior art, the present invention provides a kind of lock core rotating shaft to be isolated, and just key hole and pellet shot from a slingshot distinguish; Key shape is special, and it is moving that pellet shot from a slingshot is difficult to hook, and balk ring is arranged on the pellet shot from a slingshot; Can prevent skilled unlocking well, lock body in addition and surround lock core fully, can do firmlyer; Outside destroy is more difficult, thereby can play the antitheft effect well.

Lock body and lock core pass through the mutual fit of garden barrel, lock core is locked the body encirclement and is not exposed, key must reach the pellet shot from a slingshot district through key hole and inner slit, the shake-up pellet shot from a slingshot, rotational lock core is opened lock.The process and the principle of unblanking are following: key is a band handle arc cylinder key, inserts key hole when the key termination and arrives the bottom, and at this moment on the key narrow handle just in time is in the slit port on slit and the lock body end inner cylindrical body in the lock core shaft; At this moment key can rotate to a direction; During rotation, the narrow handle of key gets in the above-mentioned slit, and drives in the arc cylinder body entering cylinder gap, garden; Be rotated further key; Arc cylinder body finally arrives the pellet shot from a slingshot district, the indenture on it just in time with the pellet shot from a slingshot district on the pellet shot from a slingshot fit, make that the contact surface of pellet shot from a slingshot and lock core marble just in time is in the lock body and lock body inner core face and lock core urceolus contact surface place; At this moment key just can make two kinds of pellets shot from a slingshot produce to separate again, and lock core can be rotated further certain angle and drive and stir grid lock is opened.Because the outer axial face termination of pellet shot from a slingshot is provided with the resistance trace, locality is correct when opening with original key, and pellet shot from a slingshot does not produce crooked; Thereby do not hinder the smooth unlatching of lock; When tightening lock core by force with external force, pellet shot from a slingshot produces with the lock core marble bore edges and engages, thereby is difficult to stir all pellets shot from a slingshot.The structure that should lock in addition, uncinus is difficult to reach, even if reach; Be difficult to again firmly accurately, even if use nonconventional approaches to reach firmly accurately, but pellet shot from a slingshot also is difficult to separate with the pellet shot from a slingshot bore edges; Because all there is balk ring the pellet shot from a slingshot termination up and down, in case when having external force to tighten, an end of pellet shot from a slingshot will be stuck by lock body pellet shot from a slingshot hole and lock core marble hole edge in pellet shot from a slingshot or the lock body in its lock core; As it is loosening to tighten external force; All pellets shot from a slingshot playback immediately again so, thereby this design can prevent to stir and means such as vibrate pellet shot from a slingshot in pellet shot from a slingshot in the lock core and the lock body is separated, and reaches the purpose that the twisting lock core is opened lock.
