Abstract
The utility model provides an automatic lock for an anti-theft rolling curtain door, comprising an opening control mechanism and a lock hook mechanism which is connected with the opening control mechanism which is installed on the rolling curtain door, and the lock hook mechanism which is positioned under the ground is controlled by the opening control mechanism. The utility model has high anti-theft performance and convenient use.
Description
The utility model relates to a kind of anti-theft rolling blind door automatic locking.
Existing rolling door snaps in by the two movable locking plates that laterally move in the slotted eye on a both sides and locks a door.Because movable locking plate is also longer than half of gate-width degree, as long as stealer is a sled firmly, and locking plate then is out of shape the slotted eye that withdraws from a both sides, is opened, so this lock safety performance is poor, particularly the rolling door that the standard width of a room in an old-style house is big at all can't be antitheft.
In view of above reason, the purpose of this utility model is in order to provide a kind of theftproof performance good, anti-theft rolling blind door automatic locking easy to use.
The purpose of this utility model is achieved in that the unlatching controlling organization that has in the utility model on the rolling door of being contained in, and controlling organization controls is positioned at underground latch hook mechanism (referring to Fig. 1～Fig. 5) with being opened of opening that controlling organization is connected.
Housing on the rolling door of being loaded on is arranged in the above-mentioned unlatching control structure machine, be contained in the lock on the housing, be positioned at the cam that rotates with lock core on the lock core that is contained in of housing, one end of steel wire is connected on the cam, the connecting rod that is connected with the steel wire other end is arranged in the latch hook mechanism, be contained in underground transverse axis, lock housing is housed on the transverse axis, be positioned on the lock tooth of lock housing double wedge is arranged, alligator is contained in lock housing successively, on one end of lock tooth and connecting rod and the lock tooth can swing with connecting rod, be articulated in locking automatically in the lock housing have the groove that cooperates with transverse axis and cooperate with double wedge on locking tooth on the hook recessed tooth (referring to Fig. 2～Fig. 5).
On the above-mentioned lock housing chute is arranged, alignment pin is through on the chute and is connected (referring to Fig. 4) with connecting rod.
Being positioned at lock tooth top portion place on the lock housing in the above-mentioned latch hook mechanism has spring groove, spring to be loaded in the spring groove and an end presses closer in lock tooth top portion (referring to Fig. 4).
In the above-mentioned latch hook mechanism spring groove is arranged, steady pin is through on the spring groove and is fixed on the lock housing, and the end that spring and spring are housed in the spring groove presses closer on steady pin (referring to Fig. 4).
Be respectively arranged with in above-mentioned unlatching controlling organization and the latch hook mechanism and be connected the steel wire adjustable component, connecting has screw thread to be contained in hollow adjusting screw on housing or the lock housing in the steel wire adjustable component, with hollow adjusting screw nut engaged, the two ends of steel wire are passed the hollow adjusting screw on housing and the lock housing respectively and are fixed on (referring to Fig. 2, Fig. 4) on cam or the lock housing, by connecting the length that the steel wire adjustable component can be regulated steel wire.
When using the utility model, with key clockwise direction rotary locking cylinder, drive the cam rotation and drive steel wire, steel wire drives connecting rod swing, double wedge on the lock tooth is thrown off with the recessed tooth of locking automatically on the hook, automatically lock spring on the hook and make and lock hook automatically and be in enable possition (be that groove leaves transverse axis, rolling door is opened), on the contrary with rolling door down by being the automatic blocking door.
Compare with existing rolling screen door lock, the utlity model has following advantage:
1, pick-proof: adopt the lock tooth and lock hook automatically, reach optimum state, can bear the above sled power of 500kg;
2, anti-saw: the utility model door lock one is locked tooth and is locked hook automatically and can adopt the proprietary material quenching to form, and is difficult to sawed-off with hacksaw;
3, antitheft: in a single day door lock is locked into the position, and latch hook and lock tooth tightly connect together, and latch hook gives with ground and buries ironware hook jail, is being to open rolling door outdoors, and theftproof performance is good;
4, anti-drilling;
5, easy to use.
