The utility model content
The purpose of this utility model is the above-mentioned defective that overcomes prior art, and a kind of Door lock is provided, and after this lock pins, even its tapered end is prized, can not illegally be opened.
This locks further improvement purpose is after pinning with key, to use cubicle switch not unblank.
The technical scheme that the utility model solves the prior art problem is: Door lock comprises tapered end, locking bolt, locking bolt seat and shell, the locking bolt seat is positioned at shell, which is provided with and stir groove, one side connects locking bolt, shell is provided with detachable backboard, the backboard inboard is provided with the driver that can freely rotate, driver is provided with the locking bolt seat and stirs taking off post of groove fit, the lock core of tapered end is provided with driver blade, this driver blade matches with the driver blade jack on the driver, be respectively equipped with two locking grooves on the described driver both sides of the edge, backboard is provided with the arresting lever that is rotatably connected with backboard, and arresting lever is provided with the termination that cooperates with locking groove, arresting lever back-moving spring one end connects arresting lever, the other end is fixed on the backboard, and described tapered end is provided with anti-theft bar, and backboard is provided with the anti-theft bar jack supporting with this anti-theft bar.After this lock is installed, driver blade on the tapered end inserts the driver blade jack of driver outside backboard, the anti-theft bar jack that anti-theft bar on the tapered end is passed on the backboard probes in the shell, arresting lever is pressed on the anti-theft bar that probes in the shell under the effect of back-moving spring, anti-theft bar is blocked arresting lever, make it to continue to shift to driver, if sled lower lock head, the anti-theft bar that probes in the shell is come by related dial-out, and arresting lever is shifted to driver under the effect of its back-moving spring, be pressed on the edge of driver, rotate driver, in case forward the locking groove at driver edge the end of arresting lever to, this termination will be stuck in this groove, and driver can't be rotated.
The opposite side of described locking bolt seat can be provided with the locking plate that is rotatably connected with it, locking plate back-moving spring one end connects locking plate, the other end is fixed on the locking bolt seat, when using cubicle switch lock lock, driver is motionless, locking plate is positioned at the driver right side (according to direction shown in Figure 3, down together), interior driver moves from right to left by the interior shooting the lock-bolt seat that takes off post, locking bolt leans out in shell, and on door lock, the locking plate upper end is kept off on the right by taking off post on the driver, at this moment use to use all shooting the lock-bolt seats to the right of cubicle switch or key, lock is opened; If use the key lock lock, when driver rotates, the related locking plate of locking bolt seat moves to right together, take off post and when driver rotates, move in a circle, locking plate moves past below taking off post when being positioned at eminence taking off post, do not taken off post and blocked, after locking lock, locking plate is positioned at the driver left side, at this moment uses key still lock can be opened, if but use cubicle switch, driver was motionless when interior driver rotated, and the locking bolt seat is taken off post and blocks on moving to left and draw-in groove (or other positions) on the locking plate will being stuck in take off post, the locking bolt seat can't move, and also just lock can't be opened.
Since the utility model increased arresting lever and with the supporting structures such as anti-theft bar of arresting lever, even stealer also can't be opened lock outdoor with the tapered end of door lock sled down at all; Owing to increased driver blade, the user goes out to lock behind the door with key, even stealer goes out in the inlet chamber from window etc., also can't unblank from indoor, has therefore greatly improved the theftproof performance of lock.
