Description

Multifunctional assembled lockset protective device

Technical field

The utility model relates to a kind of lockset protective device, and particularly a kind of security door, labeled door etc. are gone up the multifunctional assembled lockset protective device that uses.

Background technology

Lock body is one of most critical parts of security door, labeled door etc. with the lock fork; The lock fork is weldingly fixed on to be locked up and down on the fork arm; Their quality directly influences anti-theft security performances such as security door, labeled door, therefore how to protect lock body and is not damaged with the lock fork, makes its normal operation seem excellent in important.General way is backing plate in the inboard welding of the about door face board left and right sides in the industry at present, and lock body is installed in the door leaf side through screw, and the hanging hole of locking fork arm up and down is corresponding to be connected with the last lower draw-bar of lock body.In use mainly there is following problem: the one, though left and right sides backing plate can improve the anti-drilling ability at lock body position; But lock body only leans on the panel fixed screw to fix; When particularly fixed screw was loosening, rocking appearred in lock body easily, and flexibility is bad when causing opening and closing lock.The 2nd, when being connected with hook owing to the lock fork arm, the lock fork arm is not located, position-limit mechanism, and stationarity was poor when the lock fork arm moved up and down, and the unhook phenomenon appears in the lock fork arm, causes door leaf to open or to lock.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have desirable product to emerge so far.

Summary of the invention

Install and use existing above-mentioned deficiency in the process for overcoming existing lock body, the purpose of the utility model provide a kind of simple and reasonable, lockset open light flexibly, move the multifunctional assembled lockset protective device reliable and stable, that theftproof performance is good.

The utility model solves the technical scheme that its technical problem adopted; It comprises lock body, locks fork arm and lock body protection mechanism up and down, and the upper and lower side of lock body is provided with lower draw-bar, and described lock body protection mechanism comprises left and right sides backing plate, liner plate reaches carriage up and down up and down; Liner plate and left and right sides shim connect to form the rectangle protective up and down; Carriage is fixed on the rear end of rectangle protective up and down, and the front end of rectangle protective is that lock body inserts mouth, and the end of lock body is inserted on the bayonet socket that carriage is formed up and down; Correspondence is provided with lock fork arm installing hole on the liner plate up and down, and the link of locking fork arm up and down is connected on the lower draw-bar through the hanging hole correspondence after passing and locking the fork arm installing hole.

Be respectively equipped with guide groove on the said link of locking fork arm up and down, lock fork prerotation vane interts in guide groove and correspondence is fixed on up and down on the liner plate up and down.

After adopting said structure, following advantage and effect are relatively arranged with prior art:

The one, lock body is fixed on the door leaf through four screw holes on the panel; The lock body end just plug-in card on the bayonet socket that up and down carriage is formed; Lock body and whole door leaf strong bonded are integral, so to rock can not appear in lock body, have effectively improved the stability and the application life of using.

The 2nd, owing to being respectively equipped with guide groove on the link of locking fork arm up and down; Lock fork prerotation vane interts in guide groove and correspondence is fixed on up and down on the liner plate up and down; Not only can improve the stationarity of locking fork arm and moving up and down, the flexibility of unblanking; But also can thoroughly stop to lock the problem that fork arm and last lower draw-bar break off relations and cause door leaf to open or not lock, thereby improved the flexibility and the reliability of unblanking.
