Description

A kind of mechanical antitheft lock

Technical field

The present invention relates to lock technology field, more particularly to a kind of mechanical linkage theftproof lock.

Background technology

Lock has very close relationship in human lives, as indispensable work in people usually life Tool is related to the safety of each family, unit and public place, with progress of the epoch, the mankind are to the various of lock Performance also has higher requirement.At present, anti-theft lockset structure on the market and a great variety of models, generally can be divided into mechanical type anti-theft Lock and two major class of electronic type theftproof lock, electronic type theftproof lock are easily replicated, and safety is not high.Electronic type theftproof lock is being unlocked When, by outer grip hand-motion, internal paddle is driven using the transmission between the gear and gear in unlocking apparatus, so as to drive master Lock tongue moves, and realizes operation of unlocking and lock；But such structure needs that gear forces is overcome to act on, therefore in unlocking operation When, larger strength is needed, is caused inconvenient；And gear type is unlocked, and is also unfavorable for Rapid reset, is caused to user all It is mostly inconvenient.

Mechanical antitheft lock, the opening and closing of theftproof lock are realized by the interaction between machinery, and reliability is high. The basic structure of existing mechanical anti-theft lock is essentially all similar, and lock tongue develops into five tongue of three-dimensional via single direction Formula mechanical anti-theft lock pushes directly on lock tongue with lock core, and the theftproof lock of this structure designs not reasonable in structure, and structure is multiple It is miscellaneous, anti-theft performance is bad and it is also bigger to process relatively difficult, shared space, while also there are high failure rate, it is of high cost, The shortcomings of operating with inconvenience, when in use, each switch lock will use key and turn key this theftproof lock, not be Easily；Torque when turning key simultaneously is larger, and the abrasion of key and lock core is more serious；In addition, mechanical type anti-theft inclined tongue of lock Inclined-plane be directed towards outdoors, it is easy to by the thin slice with certain degree of hardness support open, so as to cause door in the feelings for not needing to key It is opened under condition, this enters the room for burglar and provides a convenient.

In conclusion the mechanical antitheft lock of the prior art, other than there is technical unlocking, due also to knot There are many defects on structure, and bring pick-proof, crashworthiness, anti-spreading performance bad, in other words, the safety of tradition machinery formula theftproof lock Anti-theft performance either precautionary technology has been unable to meet demand in terms of opening or taking precautions against the i.e. destructive unlatching of inartful.

A kind of mechanical antitheft lock of the present invention is due to using the above structure, having the advantages that：

1st, for a kind of mechanical antitheft lock of the present invention using mechanical linkage, linkage mechanism is simple, process and assemble is convenient, makes At low cost, flexible to operation, the present invention is by main tongue component and labella component jointly to the upper and lower and side three of antitheft door To being locked, there is multiple pick-proof and anti-theft function, anti-theft performance is good；And the present invention and the unlocking mode of existing theftproof lock are not Together, the present invention is not required to turn key, and lock can be realized as long as inserting a key into lock core and pulling driving lever handle, not only operation letter It is single, time saving and energy saving, it also reduces and turns the action of key and prevent key accelerated wear test；Simultaneously because the mechanical type anti-theft of the present invention Lock assembly is relatively fewer, and transmission parts structural strength is high, therefore with very high pick-proof, anti-theft, it increases criminal and passes through The difficulty of violent means unlatching burglar-proof door；The main lock tongue of the present invention and secondary lock tongue linking mechanism are relatively independent, flexibility during use Well, there will not be malfunction, reliability is high.

2nd, the present invention is provided with main tongue locking device on the positioning support of main lock tongue, when antitheft door is in the lock state, Under the action of the spring, bolt is always positioned in the elongated slot of main lock tongue upper surface the main tongue dead bolt of main tongue locking device, if Criminal attempts to use the thin slice with certain degree of hardness to open main lock tongue from supporting outdoors, and main lock tongue is to lock shell contract one at this time After measured length, the bolt in elongated slot can prevent main lock tongue from continuing to lock shell contract, therefore main lock tongue cannot be received completely It is reduced in lock shell, antitheft door cannot also realize unlatching, avoid criminal in the case where not needing to key by doorway It opens, effectively raises the anti-theft performance of the present invention.

3rd, the present invention is both provided with labella locking device on the upper positioning support and lower positioning support of labella component, and And offer lock hole I and lock hole II accordingly respectively in upper connecting rod main body and lower pull rod main body；When upper lock tongue and lower lock tongue Extend on the outside of lock shell（I.e. antitheft door is in locked state）When, if by the labella dead bolt handle of labella locking device to Under press, labella dead bolt is made to be located in lock hole I, whether there is key at this time, cannot be made by pulling driving lever handle Upper lock tongue and lower lock tongue are to lock shell contract, that is to say, that antitheft door is in and locks state at this time；When upper lock tongue and lower lock tongue When being contracted in lock shell completely, if the labella dead bolt handle of labella locking device is pressed downwards, make labella dead bolt In lock hole II, upper lock tongue and lower lock tongue are always maintained at being contracted in lock shell, i.e., only have main tongue component to participate at this time anti- Steal the locking of door and labella component is not involved in the locking of antitheft door, when user room away from keyboard can use this function, increase The using flexible of the present invention.

4th, the present invention is additionally provided with quickly unlocking driving lever component, by the interior driving lever handle for pulling quickly unlocking driving lever component Or outer driving lever handle, lock tongue driving lever is made to drive main lock tongue column and drives main lock tongue to lock shell contract；When user needs temporarily When withdrawing from a room and returning quickly, labella locking device can be coordinated to realize of short duration leave using quickly unlocking driving lever component It is not required to function of the key with regard to energy fast and easy unlatching burglar-proof door afterwards.

5th, the present invention is additionally provided with driving lever limiting device on the right side of quickly unlocking driving lever component, can be limited by driving lever Device prevents quickly unlocking driving lever component from working.

6th, a kind of mechanical antitheft lock of the present invention is additionally provided with extension bar on the outside of lock shell, can be light by extension bar Key is compressed in keyhole by ground completely, and the smaller user of the strength such as old man and child is facilitated to use.

A kind of mechanical antitheft lock of the present invention is further described with reference to the accompanying drawings and examples.
