Abstract
The utility model relates to a shutter door lock, in particular to a shutter door lock with a back locking device. The shutter door lock comprises a lock body, a lock core, a lock tongue and a back locking device, wherein the back locking device is installed on the lock tongue on one side of the lock body, a pin clipping hole matched with the back locking device is also formed on the lock tongue, and the back locking device is fixed on the lock tongue close to the lock body through the pin clipping hole arranged on the lock tongue to fix the lock tongue. When the pin tumbler of the lock core is damaged illegally and rotated, because of the obstruction of the back locking device, the lock core can not be rotated and can not drive the lock tongue to finish the retraction process, so that the pin can not be drawn back from the pin hole, and the shutter door can not be opened. When the house owner opens the door, the clip can be drawn out from the pin hole only by pressing the movable clipping plate of the back locking device, and then the shutter door can be opened normally. The shutter door lock solves the problem that after the pin tumbler of the prior shutter door lock is damaged illegally, the shutter door is easy to illegally open, and has the advantages of simple structure and convenient installation and operation. Furthermore, the shutter door lock is suitable for locations such as business locations where persons are on watch inside the doors and warehouses.

Summary of the invention:
The purpose of this utility model is: provide a kind of and on the dead bolt of lock body both sides anti-lock device is housed, after anti-lock device pins, reach that lock core marble is drawn out or by after the unauthorised broken, lock core can not drive the dead bolt contraction and latch is withdrawed from pin hole, the purpose that rolling-gate can not illegally be opened; And the rolling gate door lock that has anti-lock device with characteristics such as simple in structure, easy to install.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of rolling gate door lock that has anti-lock device, it is made of lock body, lock core, dead bolt and anti-lock device, it is characterized in that: at least one anti-lock device is housed on the dead bolt of lock body one side and is shaped on the pin hole supporting with it.
Described anti-lock device is made of anti-lock device base, movable clamp, bearing pin and spring, and anti-lock device base and movable clamp flexibly connect by bearing pin, and spring is equipped with at the bearing pin middle part, and a side of movable clamp is shaped on buckle.
The anti-lock device base of described anti-lock device places the bottom surface of dead bolt, and movable clamp and spring place the surface of dead bolt.
Described anti-lock device can slide on dead bolt.
The utility model beneficial effect compared with prior art is: the utility model adopts anti-lock device is housed on dead bolt, pin dead bolt by the pin hole on it, stoped lock core marble to be drawn out or effectively by after the unauthorised broken, latch is withdrawed from pin hole, reach the purpose that rolling-gate can not illegally be opened.Do not need to change the structure of existing rolling gate door lock, have simple in structurely, cost of production is low, and characteristics easy to install are particularly suitable for the commercial location of Attended mode or the rolling-gate of merchandise warehouse and install and use.
Description of drawings:
Fig. 1 is the structural representation that has the rolling gate door lock of anti-lock device;
Fig. 2 is the A-A sectional view that has the rolling gate door lock of anti-lock device.
Among the figure: 1, lock body, 2, lock core, 3, dead bolt, 4, anti-lock device, 5, pin hole, 6, the anti-lock device base, 7, movable clamp, 8, bearing pin, 9, spring, 10, buckle.
The specific embodiment:
This rolling gate door lock that has anti-lock device is made of lock body 1, lock core 2, dead bolt 3 and anti-lock device 4.Lock core 2 is contained in the middle part of lock body 1, and two dead bolts 3 are contained on the both sides of lock body 1, and links with lock core 2; On one of them dead bolt 3 anti-lock device 4 is housed, anti-lock device 4 can slide on dead bolt 3.Be shaped on the dead bolt 3 and the supporting pin hole 5 of the buckle 10 of anti-lock device 4, pin hole 5 should be arranged on the place (referring to accompanying drawing 1) near lock body 1 as far as possible.
Described anti-lock device 4 is made of anti-lock device base 6, movable clamp 7, bearing pin 8 and spring 9, anti-lock device base 6 and movable clamp 7 flexibly connect by bearing pin 8, spring 9 is equipped with at the middle part of bearing pin 8, is shaped on the buckle 10 supporting with pin hole 5 on the side of movable clamp 7.The anti-lock device base 6 of anti-lock device 4 places the bottom surface of dead bolt 3, and also promptly by the one side of rolling-gate, movable clamp 7 and spring 9 place the surface of dead bolt 3, make dead bolt 3 pass anti-lock device 4 (referring to accompanying drawing 2).
This rolling gate door lock that has anti-lock device is suitable for places such as the commercial location of indoor Attended mode or merchandise warehouse.During use, rolling gate door lock is locked indoor, anti-lock device 4 is slided to lock body 1 direction along dead bolt 3, when the buckle 10 on movable clamp 7 one sides after the effect of spring 9 falls in the pin hole 5, because of being subjected to the elastic force effect of spring 9, anti-lock device 4 is stuck fixing.At this moment, if the pellet shot from a slingshot of the lock core 2 of rolling-gate is drawn out or by after the unauthorised broken, lock core 2 can't rotate, dead bolt 3 can not be withdrawn, and latch can't withdraw from pin hole, then reaches the purpose that rolling-gate can not illegally be opened.
When owner will normally open rolling-gate, only need push the movable clamp 7 of anti-lock device 4, make the buckle 10 of movable clamp 7 one sides break away from pin hole 5, the anti-lock device 4 that slides in the other direction more is not stuck anti-lock device 4, and rolling gate door lock can normally be opened.
