Abstract
The utility model relates to a double-plug anti-theft lock which comprises a lock shell (1) and lock cores (2) which are arranged laterally in symmetry inside the lock shell and is characterized in that a toggle wheel (8) is arranged in the middle of the lock shell. A through hole I (8.1) is formed in the middle of the toggle wheel. More than one groove is formed in the inner wall of the through hole I. Circular drive components (9) are symmetrically arranged at two sides of the toggle wheel. Bosses matched with the grooves are arranged on the external circular surfaces of the circular drive components. A through hole II (9.3) is formed in the middle of the circular drive components. A spring rivet (10) is sleeved inside the through hole II. A spring is arranged between the circular drive components. The double-plug anti-theft lock is capable of improving simultaneous unlocking of two sides of a lock through reasonable improvement of the structure, at the same time improving safety performance of double unlocking through the design of the toggle wheel and the drive components.
Description
Technical field
The utility model relates to a kind of lockset, relates to the two slotting theftproof lock that a kind of two can be opened lock simultaneously.
Background technology
The cylinder lock that is arranged in door is comprised of lock housing and two transversely arranged lock cores usually, all is connected with trackwheel by driving member between two lock cores.When key insertion keyhole put in place, key just in time ejected lock core marble hole with upper pellet, simultaneously driving member is pushed to the lock core of another side.At this moment, turn key cylinder and just can rotate, drive simultaneously driving member, then stir dead bolt by driving member drive trackwheel lock is opened.Such action is in door, all can complete outdoors.Therefore, door is inside and outside all can turn lock core and lock is opened.But forgotten to pull out when there being the people key to be inserted in the interior lock core hole of door, and the people is when outdoor, even this person still is difficult to from opening outdoors this lock with an adaptive key.Its reason is: that key in door is pushed lock core oneself driving member on one side to other end, and when inserting key again, key is withstood and can not put in place by own driving member on one side in the other end of lock core hole when inside and outside, causes can't opening.The patent No. is that 201220032994.1 Chinese patent " two cylinder lock of opening " discloses a kind of lock that can open inside and outside door, the problems referred to above have been solved, this lock is mainly to realize two opening by the driving member of thumb wheel both sides, having opened draw-in groove on driving member coordinates with key, this structure also has been with a problem simultaneously, the person of unblanking can insert keyhole by a hard wire, when the medium hard steel silk is inserted in draw-in groove, lock can be opened equally, greatly reduce the security performance of this lock, allow the thief have an opportunity to take advantage of.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of two slotting theftproof lock is provided, and tightly can be not simultaneously will lock at lock two unlatchings, prevents a situation about can't open, and the safety that the while can be improved lock prevents theft.
the purpose of this utility model is achieved in that a kind of two slotting theftproof lock, it comprises lock housing and is symmetrical set lock core in lock housing, middle part in described lock housing is provided with thumb wheel, the middle part of described thumb wheel has through hole I, have at least one groove on the internal face of described through hole I, be symmetrically arranged with circular driving member on the both sides of described thumb wheel, be provided with the boss that matches with groove on the periphery of described circular driving member, the middle part of described circular driving member has through hole II, being provided with cover in described through hole II has the rivet of spring, the head of described rivet is provided with collar, be provided with spring between described circular driving member.
Have groove I and groove II on the internal face of described through hole I, the groove depth of described groove I is darker than the groove depth of groove II, the groove width of described groove I is narrower than the groove width of groove II, is provided with the boss I and the boss II that match with groove I and groove II on the periphery of described circular driving member.
Compared with prior art, the beneficial effects of the utility model are:
The utility model improves by Rational structure, realized the function that to unblank simultaneously in the lock both sides, solved existing lock and forgotten to pull out because there being the people key to be inserted in the lock core hole of a side shortcoming that opposite side can't be unblanked, the design of while thumb wheel and driving member can improve the security performance of double opening lock.
