CN2567306Y - Lockset structure of one-way opened - Google Patents

Abstract

The utility model relates to a one-way opened lockset structure, which is characterized in that a main driving sheet in a lock shell links with a lock bolt and extends outwards, while a control sheet is arranged at the lateral side of the lock bolt; the control sheet extends out of the lock shell body by a convex pin part; when the convex pin part abuts on a door frame with the closure of a door plate, the control sheet slips inwards with the convex pin part; the other clamping sheet driven by an elastic element can be clamped on the main driving sheet linking with the lock bolt; as a result, the lock bolt can maintain the locking state; both sides of the lock shell body are respectively provided with a rotary handle (indoor and outdoor rotary handles), and the rotary handles can drive two rotary sheets separately; when either rotary handle is wrenched, a rotary sheet engaged with the rotary handle can be driven to turn the clamping sheet; the lock bolt can be received and pulled inwards by the main driving sheet so as to open the door plate; a lock core is additionally arranged in the lock shell body, and can drive a locking clamping pin to slip so as to clamp the outdoor rotary handle to engage with the rotary sheet. Therefore, the effects of one-way lock and clamp (or open) can be achieved. Meanwhile, the utility model can avoid the open of a door plate by a thin sheet body extending in the door frame.

Description

The lock structure of unidirectional unlatching

Technical field

The utility model is the lock structure about unidirectional unlatching, belongs to people's daily necessities.

Background technology

Common lock structure, for ease of producing the stopper function at closing time automatically, more than the locking bolt that a tool elastic telescopic is set in the lock structure, utilize this locking bolt to close on one of keyhole side in closing the door bevel is set, can cause locking bolt in inwardly folding at closing time, and under nature, form reverse stopper, when avoiding not using handle, be subjected to improper external force (as: wind or cat and dog, children pushing and pressing) and open, reach temporary transient stopper door-plate, make it keep closed condition; Yet mostly the lock structure of this kind tradition, the locking bolt of its above-mentioned tool elastic telescopic are all can be opened by inside and outside handle, and do not have the sincere effect of lock; Must establish at least one locking bolt in addition and implement lock moving work, otherwise can't reach anti-theft feature, thus, the overall volume of lockset certainly will can't be dwindled, and various numbers of elements increase, and structure is also complicated thereupon, is unfavorable for present keen competition.

For improving the disappearance of above-mentioned conventional lock structure, in open on the market lock structure, rotation with control handle is arranged (when lock is sincere, stop handle to rotate, and can't open locking bolt with elastic telescopic), to reach the identical sincere effect of lock, yet, this kind lock structure, the locking bolt to the tool elastic telescopic does not have suitable lock sincere, and,, and can reach the effect of unlatching by the bevel of this tool elastic telescopic locking bolt of extruding easily for burglar or effractor stretch into slit between door-plate and the doorframe with the thin slice body.

Summary of the invention

The utility model is the lock structure that a kind of unidirectional unlatching is provided at the defective of above-mentioned lock structure existence, this structure comprises the lock housing body, locking bolt, main driving chip, first, the second revolving fragment group, control strip, parts such as clamping sheet and locking cotter, wherein being provided with main driving chip interlock locking bolt in the lock housing body stretches out, the side of locking bolt is established a control strip, this control strip is that to convexedly stretch in lock housing in the same way with protruding pin portion and locking bolt external, make protruding pin portion with door-plate close and when contacting at doorframe, control strip is inwardly slippage thereupon, can make another be subjected to the clamping sheet stopper of flexible member driving and the main driving chip of locking bolt interlock, by making locking bolt keep the kayser state, avoid burglar or effractor to stretch into slit between the door-plate doorframe with the thin slice body, the extruding locking bolt bevel and open door-plate.

The lock structure of the unidirectional unlatching of the utility model, be that two sides (indoor and outdoor) in the lock housing body are arranged with a rotating handles, can drive two revolving fragments respectively, when pulling arbitrary rotating handles, the revolving fragment that can drive linking is mutually pushed clamping sheet aside, and locking bolt inwardly reeled, be convenient to open door-plate, and establish lock core in the lock housing body in addition, can drive the locking cotter slippage, with the revolving fragment that clamping door inner rotary handle is connected, make rotating handles outdoors can't drive revolving fragment and remove the sincere state of lock, to reach the effect of unidirectional lock sincere (or unlatching).
