Abstract

The invention relates to an anti-theft structure of a mechanical lockset. The lockset comprises a lock body, a lock cover, a spring, a cam, a lock cylinder, a spring bolt, a lock plunger, a chain and a key matched with the lockset. A through hole matched with the working part of the key is formed in the lock cover. The spring is arranged between the lock cover and the cam for supporting and positioning. Criss-cross fixing is achieved through the through hole of the lock cover and a key hole of the lock cylinder. A through hole which is the same as the through hole in the lock cover is formed in the center of the cam. Two symmetrical circular holes are formed in the outer side of the lock body and are used for adjusting the angle of the hole position of the cam. During unlocking, the key is inserted in the lock cover and the cam, rotated by 90 degrees in the lock body, then aligned with the key hole and inserted for unlocking. During unlocking, the through hole of the cam is rotated to the position matched with the key hole of the lock cylinder, and a closed space is formed by the hole of the cam and the hole of the lock cover in a cross manner at the moment. Before unlocking, the size of a keyhole is changed to the size of a nail hole so that an unlocking tool can be clamped, the tool is prevented from entering the key hole, the tool is prevented from strongly twisting the lock cylinder due to the fixed through hole in the lock cover, the cam can idle in the lock body so that an electric hand drill can be effectively prevented from damaging the lock cylinder, and the anti-theft performance of the lockset is reliable.

Description

Nail hole lock and matched key

Technical field

The present invention relates to a kind of mechanical anti-theft lockset technical field, and in particular to a kind of nail hole lock and matched key, it is adaptable to safe-guard door lock, lock, padlock, U-shape lock, chain lock, safe lock etc..

Background technology

Mechanical lock comes out, and is currently one kind relatively common on the market, and just because of the extensive application of lockset technology, lockset is non-anti-theft to be become apparent, in terms of being mainly manifested in three below：1. lock core structure is made up of blade or pellet, copper makes lock core on the surface of lock, the internal structure of lock core is will appreciate that by estimating keyhole just, stealer can directly use unlocking tool or skeleton key insertion keyhole, by dialling the blade in lock core, pellet, or means reverse lock core unlocking by force by force, the modes such as bad lock core are bored with electric hand drill, easily reach the purpose for opening lockset, 2. non-former lock key can insert lock core, easily cause and mutually open by means of key and key tooth not etc. is not mutually opened, oneself key can be injected in others' family's lockhole, the lock of others' family can also even be opened, 3. the unlocking tool sold on the net, free download unlocking instructional video, the little posters of lock Wang Kaisuo glued on door, bitting can be found on the market everywhere with the technical staff for unlocking, lockset theftproof performance present as can be seen here is poor；The electric lockset of market, for example：IC card lock, Fingerprint Lock, electronic password lock, can not be used widely due to factors such as selling at exorbitant prices, suitable environments；The lock that a few minutes can just be pried open is such as ornament, it is impossible to protect the safety of property and the person.

The content of the invention

Present invention aim to address the deficiency in existing lockset theftproof performance, researching and developing a kind of lock core has hidden function, with the lock unit that the confrontational design of high security, simple structure, handling ease, non-original key are not opened；The theftproof performance of innovation can effectively pick-proof, it is anti-drilling, anti-cut, anti-saw, anti-hinge, it is anti-pound, anti-carrying（With fixture lock jail）Deng.

Realize that the concrete technical scheme that foregoing invention theft-prevention structure is designed is：A kind of nail hole lock and matched key, this lockset include the supporting key of lock body, locking closure, spring, cam, lock core, dead bolt, locking bolt, chain and lockset；The work department cylindrical bar of key is connected with key handle, there is the through-hole groove being engaged with key work department at locking closure center, locking closure forms male-female engagement with cam, locking closure through-hole groove is fixed with the right-angled intersection in 90 ° of lock core keyhole shape, cam is assemblied between locking closure and lock core and can dally inside lock body, cam center has and locking closure identical through-hole groove, has two symmetrical circular holes for adjusting the rotation position of cam on the outside of lock body.

With in key insertion locking closure and cam during unlocking, it is rotated by 90 ° in lock body and aligns lock core keyhole insertion unlocking, when key is rotated in cam, cam through-hole groove also concomitant rotation to the position being engaged with lock core keyhole, now cam path is closed with the shearing of locking closure slotted eye position, shape cross staggered seal Space Principles in 90 °, front lockhole of unlocking becomes nail hole size and can block unlocking tool, intercept skeleton key to enter inside lock core, fixed via groove on locking closure is prevented, the steel cam for rotating freely can prevent destruction of the electric hand drill to lock core, the innovative design of this lockset, change the core texture of conventional lock, security performance is improved.

Nail hole robber's lockset of the present invention and matched key use hiding lock core inside lock body, by keyhole not it is observed that the core texture of lock core, and by three hole position shearing closures on locking closure, cam, lock core, shape cross in 90 ° is staggeredly sealed up a door and is designed, the safety guard to lock core is this architecture enhanced, therefore which has the theftproof performance for insuring very much.
