Description

A kind of theftproof lock

Technical field

The present invention relates to lock technology field, refer to especially a kind of theftproof lock.

Background technology

Mechanical cylinder lock is people's the most widely used a kind of theftproof locks always.Traditional cylinder lock is due to simple in structure, and theftproof performance is the non-constant of performance of anti-technical opening particularly.In order to improve the theftproof performance of lockset, increase the difficulty of technical opening, prior art discloses a kind of safe-guard door lock, comprises the lock core of lock body, lock body inside, the key corresponding with keyhole; Described lock core is divided into main lock core and auxiliary lock core, be installed on respectively in master lock body and auxiliary lock body, described master lock body and auxiliary lock body are cast into integral structure in centre, master lock body is provided with the breach of card and spring turnover, master lock core body is provided with spring groove and card slot, and five groups of double card sheets and corresponding five groups of springs are installed respectively in card slot and spring groove; In being connected with between described main lock core and auxiliary lock core, establish thumb wheel core and thumb wheel, thumb wheel in-core is established thumb wheel axle.

Although this class theftproof lock theftproof has increased,, still there are some defects: when running into mandatory unblanking, there will be 2 kinds of situations: 1, key switch out, in lock core, causes and cannot unblank, need to look for professional to pull down lockset, take out the key in lock core, then reinstall; 2, lock core is subject to powerfully and cracked, causes door to open, the lockset that need to look for professional more to renew.Also have when running into poly-talented unblanking, professional unlocking person is pushing the pellet in lock core in locked groove, there will be a kind of " poh " ticktack and feel, easily blocks of pellet is pushed in locked groove, lock is opened.In addition, existing key of anti-theft lock is lost, and does not have another key to copy, and this theftproof lock is just useless so, the theftproof lock that can only more renew.

Summary of the invention

The technical barrier proposing for prior art, the present invention proposes a kind of theftproof lock, its when running into mandatory unblanking, its lock core rotation, cause key can switch out or lock core cracked; Pellet in its lock core in pushing locked groove, there will not be a kind of " poh " ticktack and feel, be difficult for unblanking, theftproof is strong; Key, after loss, can be made key according to the pellet group in its lock core, without the lockset more renewing, simple and convenient.

Technical scheme of the present invention is achieved in that a kind of theftproof lock, comprise master lock body and auxiliary lock body, described master lock body links together by being connected steel bar with auxiliary lock body, lock core three is installed in described auxiliary lock body, in described master lock body, lock core two is installed, lock core one is installed in one end of described lock core two, and described lock core two offers respectively lock groove two and lock groove one with lock core one on same position; In described lock groove one, lock pin and STATEMENT OF FEDERALLY SPONSORED are installed, on the end face of described lock core one, offer keyhole, on its periphery, offer bullet groove, in described bullet groove, be provided with and can push up the pellet of pressing lock pin; Thumb wheel axle and thumb wheel core are installed in the other end of described lock core two, on described thumb wheel core, thumb wheel are installed; On the periphery of described lock core two other ends, offer the draw-in groove being connected with thumb wheel core; Described lock core two is connected with lock core three by thumb wheel core.

Tool of the present invention is opened lock needs coordinating of lock core and lock core, such as lock core one and lock core two these groups, has lock groove one on lock core one, and lock pin and STATEMENT OF FEDERALLY SPONSORED are installed in lock groove one; Lock core two has lock groove two, and key inserts in lock core one, compresses pellet group, makes pellet group the lock pin jack-up that makes progress, and lock pin is STATEMENT OF FEDERALLY SPONSORED top as between lock groove one and lock groove two, and lock core one band movable lock core two rotates, and lock core two drive thumb wheels are unblanked.

Further preferably, described lock core three comprises auxiliary lock core three and main lock core three, and described main lock core three is installed in one end of auxiliary lock core three; Described main lock core three offers respectively main lock groove three and secondary lock groove three with auxiliary lock core three on same position; In described main lock groove three, lock pin and STATEMENT OF FEDERALLY SPONSORED are installed, on the end face of described main lock core three, offer keyhole, on its periphery, offer bullet groove, in described bullet groove, be provided with and can push up the pellet of pressing lock pin.

Further preferably, on the periphery of the other end of described auxiliary lock core three, offer the draw-in groove three being connected with thumb wheel core.

Further preferably, on described connection steel bar, offer respectively the installing hole that steel ball, spring are installed and the fixing hole that steady pin is installed, and installing hole and fixing hole penetrate in major and minor lock body; The collar extension place of described installing hole and fixing hole is all bolted with sealing screw; Described steel ball is used for pushing up pressure STATEMENT OF FEDERALLY SPONSORED, and described steady pin is for fixed lock core two.

Further preferably, on described auxiliary lock core three and lock core two, be separately installed with and place restrictions on auxiliary lock core three and the axially movable jump ring of lock core two.

Further preferably, described bullet groove includes five groups, and a pair of pellet is installed in every group of bullet groove, and described every pair of pellet is oppositely arranged and is provided with back-moving spring between the two.

Further preferably, described STATEMENT OF FEDERALLY SPONSORED is a bonding jumper.

Compared with prior art, the beneficial effect that the present invention possesses:

The present invention has 4 lock cores, and opening lock needs coordinating of lock core and lock core, such as lock core one and lock core two these groups, has lock groove one on lock core one, and lock pin and STATEMENT OF FEDERALLY SPONSORED are installed in lock groove one; Lock core two has lock groove two, and key inserts in lock core one, compresses pellet group, makes pellet group the lock pin jack-up that makes progress, and lock pin is STATEMENT OF FEDERALLY SPONSORED top as between lock groove one and lock groove two, and lock core one band movable lock core two rotates, and lock core two drive thumb wheels are unblanked; And wrong key is being forced to insert in lock core, can not compress pellet group and make its lock pin jack-up that makes progress, can not form the interlock of lock core and lock core; The key of mistake only can drive a lock core rotation, has like this 2 benefits: 1, key can switch out in lock core; 2, lock core is subject to powerful and cracked; Improved its application life.Can also have the present invention correctly open, be to depend on the stressed compression of pellet group jack-up lock pin, and STATEMENT OF FEDERALLY SPONSORED is pushed up as between lock groove one and lock groove two; Therefore, when running into poly-talented unblanking, professional unlocking person, when stirring pellet, is to find pellet to push the feel of tram, and its theftproof improves greatly.

Can the present invention correctly open in addition, is to depend on whether pellet group and teeth groove on the key coincide; The teeth groove that pellet group is combined to form is quite a password, user is after losing key, only the numbering of this lock need be offered to manufacturer or store, the teeth groove mould that manufacturer or store can find the pellet group of placing on record according to the numbering of lock is joined a new key, without again more renewing lock, simple and convenient economy; Should be widely promoted.
