Abstract
The utility model relates to a semicircular elastic strip anti-theft lock which comprises a lock core, a lock casing, an outer sleeve of the lock core, semicircular elastic strips, a branch control clamping strip, a locking column, elastic strip springs, a key, a branch control clamping spring and a fixed pin, wherein the lock core is provided with a plurality of semicircular elastic strip grooves according to left circumambience and right circumambience, the semicircular elastic strips which can be moved are arranged in the semicircular elastic strip grooves and the elastic strip springs are arranged on the tails of the semicircular elastic strips. The utility model has the advantage that the theft action produced because the lock is unlocked by techniques can be prevented, and thus, social stable factors are effectively improved.
Description
Technical field
The utility model relates to a kind of semicircle spring theftproof lock, belongs to hardware machinery lockset industry.
Technical background
The lockset that is using at present, because design defect and mismachining tolerance, the overwhelming majority can be by technical opening.Though I provide three kinds of design schemes in patent application document (application number is 200420086219.X, 200520078263.0,200520078392.X), they can prevent technical opening effectively, reduce mutual opening rate.But consider the different demands of the scope of application, processing cost, production technology, existing spy provides a kind of semicircle spring theftproof lock.
Summary of the invention
Purpose of design of the present utility model is to provide a kind of can reduce mutual opening rate, and can prevent a kind of semicircle spring theftproof lock of technical opening.
Design principle of the present utility model is that branch control card article is installed respectively in the lock core both sides, blocks semicircle spring by a minute control card article when lock core rotates, and realizes substep control, prevents technical opening.
The technical solution of the utility model feature is: alternately be processed with a plurality of semicircle spring grooves about dividing on the lock core, semicircle spring is installed in the groove, be processed with latch and locking mouth on the spring, the spring afterbody is equipped with back-moving spring.Be processed with branch control card article teeth groove respectively about vertically and be positioned at the locking cylinder groove on key opposite along lock core, lock core is installed in the lock core sleeve and with lock core sleeve by tight fit and is fixed together.Be processed with branch control card article hole and locking cylindrical hole on this lock core sleeve respectively, be separately installed with branch control card article and locking cylinder in the hole.When in key inserts lockset, driving lock core, lock core sleeve and rotating together, the branch control card article of lock core both sides is released groove by the branch control card article on the lock housing and is released, divide latch elder generation and the latch engagement on the semicircle spring on the control card article and block semicircle spring, it can not be moved.After continuing rotary locking cylinder and turning over an angle, the locking cylinder that the locking cylinder is touched on the lock housing is released trough rim, if this moment during this lock key, the locking cylinder can be released the locking cylinder by lock housing and release groove, and lock will be opened.When if not this lock key is unblanked, divide on the control card article latch also with semicircle spring on the latch engagement, after rotating a low-angle, locking mouth on the semicircle spring can't be corresponding with the locking cylinder, the locking cylinder can not be released by lock housing, has stoped lock core to continue rotation, can't open lockset, thereby realized control step by step, reached the purpose that prevents technical opening.
Advantage of the present utility model is to prevent the larceny that produces because of the technical opening lockset, thereby effectively improves the social stability factor.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.

Specific embodiments
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, present embodiment mainly is by lock core 10, lock core sleeve 4, lock housing 8, semicircle spring 3, divides control card article 1, locking cylinder 5, key 11, spring spring 7, divides organic assembling such as controlling card spring 9 to constitute.Design is processed with a plurality of semicircle spring grooves 18 about dividing on the lock core 10, is mounted alternately with semicircle spring 3 in the semicircle spring groove 18.As shown in Figure 4, be processed with latch 13 and locking mouth 12 on the semicircle spring 3, its afterbody is processed with a spring top platform 22.As shown in Figure 3, be processed with branch control card article teeth groove 21 on the lock core 10 about longitudinally respectively, can be meshed with the latch 14 on the branch control card article 1 shown in Figure 5.Be processed with key 20 on the lock core 10, the opposite of key 20 is processed with locking cylinder groove 16.As shown in Figure 1 and Figure 2, lock core 10 is installed in 4 li of lock core sleeves by tight fit, and is fixed together with lock core sleeve 4.As shown in Figure 6, be processed with branch control card article hole 24 and locking cylindrical hole 25 on the lock core sleeve 4 respectively, and movable branch control card article 1 and locking cylinder 5 inside are installed.As shown in Figure 1, be processed with two branch control card articles on the lock housing 8 and release groove 2 and locking cylinder release groove 6.As shown in Figure 1 and Figure 2, when drive lock core 10 rotates with lock core sleeve 4 in the key 11 insertion lock bodies, the branch control card article 1 of lock core 10 both sides is released groove 2 by the branch control card article on the lock housing 8 and is released, divide latch 14 elder generations and latch 13 engagements on the semicircle spring 3 on the control card article 1 and block semicircle spring 3, it can not be moved.After continuing rotary locking cylinder 10 and turning over an angle, make locking cylinder 5 touch the limit that locking cylinder on the lock housing 8 is released groove 6, if this moment during this lock key 11, locking cylinder 5 can be released the locking cylinders by lock housing 8 and release grooves 6, and lock will be opened.When if not this lock key 11 is unblanked, divide on the control card article 1 latch 14 also earlier with semicircle spring 3 on latch 13 engagements, after rotating a low-angle, locking mouth 12 on the semicircle spring 3 can't be corresponding with locking cylinder 5, and half garden shape spring 3 can not enter locking mouth 12, so locking cylinder 5 can not be released by lock housing 8, stoped lock core 10 to continue rotation, can't open lockset, thereby realize control step by step, reach the purpose that prevents technical opening.The utlity model has excellent theftproof performance and lower mutual opening rate.
