Abstract
The utility model belongs to the technical field of application of a lockset and particularly relates to a lock body locking mechanism linked by a lock core, comprising a lock core linked locking mechanism and a lock body, wherein the lock core linked locking mechanism is formed by a fixing base (1), a linking sheet (4), a linking spring (5), a locking bolt (2), a locking spring (3) and an auxiliary assembling screw (6); and the lock body mainly comprises the lock core (8) and a main lock tongue (7), which are located in the lock body (10). According to the lock body locking mechanism linked by the lock core, when the lock core is broken or is enforcedly detached, the linking sheet is popped out by the linking spring, so that the locking bolt stretches into a locking groove of the main lock tongue and the main lock tongue is prevented from being opened. The lock core linked locking mechanism is arranged in the lock body, so that the lockset has the level which exceeds the common structure of the existing mechanical lock on the aspects of preventing violent opening and detachment. The lock body locking mechanism linked by the lock core has the advantages of simple structure, convenience for use and reliable performance.
Description
Technical field
The utility model patent belongs to the lockset applied technical field, is specifically related to a kind of lock body blocking mechanism of the security door insertion-core lock by lock core interlock.
Background technology
The core-inset type lockset is security door main flow lockset commonly used, the first generation prevention that I apply for destroys the lock body parts of core unlatching burglar-proof door, (application number is 201220194032.6) is perfect not, and lock core linkage lock mechanism is characterized in moving the keying lockset by the thumb wheel of lock core or the dead bolt in the gear driven lock body.The theftproof of lockset depends on lock core fully, the Ministry of Public Security is by to the regulation of lock core structure and the regulation of size of key, the clear and definite anti-theft grade of lockset, but lock body is only had the structural strength requirement, there is not the requirement of anti-theft feature, so that there is very large leak in the existing machinery lockset at anti-theft capability.Because the restriction of lock core for inserting core lock design feature, and the restriction of the strength of materials that adopts, former and later two parts of lock core and easy plate are disconnected, just be in open state when taking off the disconnected lock core rear locking of plate, as long as open lockset once stirring dead bolt to screwdriver commonly used, therefore become the crime means that the offender commonly uses.
Summary of the invention
The utility model has increased the anti-theft feature of lock body by adopted lock core linkage lock mechanism technology in lock body, efficiently solves the illegal problem of opening lockset by the disconnected lock core of plate.Aspect the anti-violence unlatching, adopt Ministry of Public Security's standard code instrument in addition to open lockset even can reach, also can meet the B of Ministry of Public Security level lock standard.
The utility model provides following technical scheme:
Lock core linkage lock mechanism comprises lock core linkage lock mechanism and lock body.Lock body comprises the master lock tongue that is positioned at lock body; Lock core linkage lock mechanism: comprise holder (1), linkage piece (4), interlock spring (5), locking bolt (2), case spring (3), auxiliary assembling screw (6).
Master lock tongue (7) in mortise lock body has one group of locking grain (9).
Lock core linkage lock mechanism is positioned at master lock tongue (7) one sides of mortise lock body, and linkage piece (4) contacts with lock core (8) Outboard Sections.
A gathering sill (13) is arranged on the holder (1), linkage piece (4) is positioned at gathering sill (13), cover at ordinary times locking bolt (2), when lock core (8) breaks away from lock body, linkage piece (4) is mobile along gathering sill (13) under interlock spring (5) effect, and locking bolt (2) is ejected under case spring (3) effect.
Adopt an auxiliary assembling screw (6) fixing between holder (1) and the linkage piece (4), when lock body does not insert lock core, this screw guarantees that holder (1) and linkage piece (4) link together, when lock body is assembled on the door, back out this screw after finishing the lock core assembling, holder (1) is broken away from linkage piece (4) be connected.
The utility model is identical with the existing machinery lockset on mode of operation, and only when violence and illegal dismounting lock core, lock core linkage lock mechanism just can work, and shows the feature of Initiative Defense; So the utility model has effectively overcome the poor problem of anti-theft security that the existing machinery lock body exists, and has satisfied real requirement, has possessed the market competitiveness.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Such as Fig. 1-----shown in the of 11,
Lock core linkage lock mechanism comprises lock core linkage lock mechanism and lock body.Lock body comprises the master lock tongue (7) that is positioned at lock body; Lock core linkage lock mechanism comprises holder (1), linkage piece (4), interlock spring (5), locking bolt (2), case spring (3), auxiliary assembling screw (6).
The main body of lock core linkage lock mechanism is holder 1, a gathering sill 13 is arranged on the holder 1, linkage piece 4 is positioned at gathering sill 13, cover at ordinary times locking bolt 2, when lock core 8 broke away from lock body, linkage piece 4 moved along gathering sill 13 under 5 effects of interlock spring, and displacement is greater than the diameter of locking keyhole 15, guarantee that after lock core 8 first halfs break away from lock body locking bolt 2 can eject under case spring 3 effects.Locking bolt 2 is a ladder type cylinder, and the first half diameter is greater than the latter half, and the first half is used for bearing the pulling force of dead bolt, and the latter half is inserted in the case spring 3, equally with holder 1 need select the firm steel structure material processing and fabricating of quality.When locking bolt 2 insert the locking groove 9 of master lock tongues 7 interior after, dead bolt 7 will be stuck, only having this moment the appropriate section that adopts electric tools opposite house and lock body to tear down could the unlocking state, thereby reaches the purpose that difficulty is illegally opened in effective increase.
