Description

The rolling door safety lock

The utility model relates to a kind of rolling door safety lock.

Existing rolling door safety lock, but be by be located at below the rolling door on the crossbeam lock core constitute with the dead bolt that links to each other with lock core and transversal stretching moves, rolling door is lockable the back dead bolt and inserts the keyhole of doorframe both sides, makes the rolling door can not pull-up.Because dead bolt and doorframe have big slit, dead bolt is cut off or is prized from keyhole easily, and safety effect is poor.

The purpose of this utility model provide a kind ofly have more disguise, install easily, easy to use and be difficult for ruined rolling door safety lock.

The purpose of this utility model is to be realized by following technical scheme: its mainly by lock core, dead bolt, lock insert, limit lock catch, lower margin locking bolt, anchor nut, nut cap and lock insert cover institute and constituted.On the following fixing metal beam of rolling door lock core and dead bolt are installed, lock core is connected with the scalable mobile dead bolt in both sides, and dead bolt is corresponding with the keyhole position of both sides doorframe and can go deep into keyhole; 2 to 4 locks of fixed installation are inserted on the dead bolt of both sides, the anchor nut that will equate with the slotting number of lock is imbedded underground securely, the end face of anchor nut is parallel to the ground, the stone bolt that is provided with through hole is connected with anchor nut through screw thread, and lock firmly pins rolling door and ground after inserting the through hole that inserts stone bolt; After the pull-up rolling door, stone bolt can screw out from anchor nut, and nut cap can cover on screw; Lock is inserted cover and is fixedly mounted on the outside that lock is inserted; The indoor that lock is inserted, limit lock catch, lower margin locking bolt and anchor nut are installed in rolling door.

The utility model has the advantages that:

1, has disguise:, after on the rolling screen door lock, just more be difficult for being found because whole facility is installed in the indoor of rolling door.

2, have safety: because that anchor nut is embedded in is underground, dead bolt firmly is connected with ground with stone bolt through locking to insert, and can establish more in case of necessity and lock slotting number, and it is destroyed that safety lock is difficult for, and makes rolling door have better safety performance.

3, easy to install: this safety lock is the safeties that added on the door lock of original dead bolt structure by lock is inserted, stone bolt and anchor nut constitute, and makes the mode of locking a door with original the same, conveniently use.Owing to can cover nut cap after taking off stone bolt, effectively prevent the intrusion of dust.

4, cost is low: the metalwork that all is easy batch machining.

Further describe below in conjunction with drawings and Examples.

Fig. 1 is the utility model back structural representation.

Fig. 2 is the utility model A-A side sectional view.

Number in the figure is described as follows:

1, crossbeam 2, lock core 3, dead bolt

4, lock insert 5, limit lock catch 6, lower margin locking bolt

7, anchor nut 8, lock are inserted cover 9, rolling door

Rolling door safety lock is as shown in Figure 1 and Figure 2 mainly inserted cover (8) and is constituted by crossbeam (1), lock core (2), dead bolt (3), lock slotting (4), limit lock catch (5), lower margin locking bolt (6), anchor nut (7), lock.The bottom of rolling door (9) is fixed with a metal beam (1), lock core (2) is installed in the centre position of metal beam, the both sides of lock core are connected with scalable mobile dead bolt (3) respectively in horizontal plane, dead bolt is corresponding with the keyhole position of both sides doorframe and can insert keyhole, two locks are inserted (4) branch bilateral symmetry and are fixed on the dead bolt (3), two anchor nuts (7) are imbedded underground securely, the end face of anchor nut is parallel to the ground, (6) top of stone bolt is nut, the bottom is a screw rod, nut is provided with a through hole, screw rod is connected with anchor nut through screw thread, the outside of lock slotting (4) is spacing by two snap closes (5) that are fixed on the crossbeam (1) respectively, lock is inserted (4) insertedly in the through hole on the nut of foot bolt (6) top, the roller shutter every makes rolling door (9) firmly be connected with (6) of the stone bolt of ground line after lock core (2) pins.After rolling door was opened, stone bolt can screw out from anchor nut and take off, and nut cap is covered on screw, invaded to stop dust.Lock is inserted cover (8) and is fixedly mounted on the outside that each lock is inserted (4), inserts to hide lock.

For guaranteeing safety, lock is inserted (4), lower margin locking bolt (6) and anchor nut (7) can also install 4 covers in the lock core both sides respectively.

Lock is inserted the indoor that (4), lower margin locking bolt (6) and anchor nut (7) are installed in rolling door, to strengthen the disguise of rolling door safety lock.When using this rolling door safety lock, with original the same, the rolling door of leaving behind is inserted lock core (2) with key, when dead bolt (3) is locked the wall keyhole, will lock slotting (4) simultaneously and lock lower margin locking bolt (6), makes rolling door have better safety performance.
