Abstract

The utility model breaks the tradition and a built-in lock face is installed on the door inboard, and robbers can not observe and judge built-in lock type and unlocking method. The lock hole direction is not over against the door opener, and compared with rotating 90-270 DEG in conventional direction, the robbers need to unlock the lock in reversal direction with backhand. Normal hand feelings and direction senses are completely changed, and the robbers feel for operation in a strait gap and can not depend on normal training and hand feelings to clasp the built-in lock. But with a key at hand, the owner can unlock easily. The lock hole is not vertical with the door face, but in parallel, making tools like electric hand drills unable to approach and align with the built-in lock. Each critical component is installed in a closed system composed of channel steels and steel plates, unable to be destroyed by strong force.

Description

Latent lock safety door

The utility model is the inboard that a kind of door lock is installed in door, the domestic safety security door of the conventional direction rotation of lockhole direction ratio 90-270 degree

The locking face that present common characteristic of safety door on the market is a door lock is installed in the outside of door, and lockhole is over against the door opener, and lockhole is vertical with the shop front, and this has become tradition, and 1,100 of all times almost like this always.Though it has made things convenient for owner, also for those well-trained robbers provide convenience, they can judge door lock type and crack method by observing, can rely at ordinary times training and the feel of sensitivity, with the instrument hook lock that opens the door; Or carry out strong destruction with instruments such as Electric portable drill, hacksaw, ripping bar, hammer, file, cutter, pincers.Particularly present three people families increase, and the man and wife often works outside the home in pairs or travels, unmanned guard in the family, and the house is one again and closes to the greatest extent that neighbours seldom come and go, and this shortcoming of safety door is loomed large with serious.

The purpose of this utility model is to break the tradition of above-mentioned safety door, a kind of new latent lock safety door is provided, its decapacitation is taken precautions against outside the common thief, can also take precautions against special training, can observe and judge the door lock type, the method of separating brokenly, and equipped Electric portable drill, the robber of various tools such as hacksaw, ripping bar, pincers, cutter, file, hammer.And owner really can easily unblank with key.

This is suitable for novel purpose and realizes that by latent lock safety door shown in Figure 1 it comprises following several characteristics:

1. the locking face of safety every lock anomaly is installed in the outside of door, and is mounted in the inboard of door, the robber can't be seen look into and judges door lock type and crack method.

2. the lockhole direction of intrinsic safety air cock is anomaly facing to the door opener, but from conventional direction rotation 90～270 degree, thus with the robber at ordinary times training and daily life decades in the sense of direction that forms and feel is completely different or fully opposite.Must backhand when the robber unblanks, oppositely grope operation only holding several fingers narrow space at hand, instrument is difficult to freely rotate, and does not know door lock type, feature again.In this case, any robber can't finish feel is required very meticulous hook lock operation, and lock can't hook opens the door.

3. safety door lock hole is anomaly vertical with the shop front, turn 90 degrees parallelly with the shop front but revolve, and makes the drill bit of Electric portable drill can't be close, more can't aim at lockhole, can't destroy door lock.

4. the vitals of intrinsic safety air cock all is installed in the thick channel-section steel, forms totally-enclosed protection system by channel-section steel and steel plate, and the robber can't strong destruction.

5. changing in the past, the safety door single-point lock is decided to be 2 lockings, thereby shortened the distance from the origin of force to the door lock when robber forces open the door, reduced the moment the when robber forces open the door, the robber needs just can reach same moment with bigger strength, thereby make equally under the situation of a material using, the utlity model has higher fastness.Also available link rod changes safety door into 3 lockings after changing the locking bar direction, further improves the firmness of safety door.

6. the intrinsic safety air cock has built-in lock and the totally three layers of strick precaution of the latent lock of twice, and owner can be according to local security condition, and outer artificial situation of house person and personal inclination determine the mode of locking a door flexibly.

7. the inside and outside two sides of intrinsic safety air cock all is a steel plate, and the centre is welded into tight steelframe net with angle steel, thereby intrinsic safety air cock intensity is very high.

8. the intrinsic safety air cock is equipped with and touches quick alarm buzzer, when robber's attempt is forced open the door, when firmly clashing into, will give the alarm and tell the owner robber presence.

Owner if key just can unblank easily at hand.The inside and outside both sides of safety door hide smooth bright and cleanly, make no sign, and conceal lock from indoor also cannot see, and do not affect the appearance.

The utility model is compared with present various safety doors on the market, and its advantage is: well-trained robber, can't crack latent lock, and can't drive latent lock with the special tool hook, or carry out strong destruction with instruments such as Electric portable drill, hacksaw, ripping bar, cutter, file, pincers, hammers.The intrinsic safety air cock is 2 lockings, and fastness is higher under situation about making with same material.Owner can select the multiple mode of locking a door according to different situations.

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:

Fig. 1 is latent lock safety door structure elevation

Figure A-A and B-B are protection box profiles

Among the figure: (1) locking bar, (2) channel-section steel, (3) baffle plate, (4) latent lock 1, (5) knocker, (6) aperture of door, (7) slide plate, (8) dividing plate, (9) latent lock 2, (10) badge.

From scheming as seen; safety door is placed in the protection box of being made up of channel-section steel (2) and baffle plate (3) by the knocker of locking bar (1) lock jail, locking bar, has only owner just can open the latent lock (4) of protecting box with key, pushes baffle plate (3) then open; break knocker (5) into two with one's hands, draw back locking bar, the door just opened.Owner turns left, pushes open slide plate (7) as long as hand is put in the door from aperture of door (6), and latent lock has just revealed.In this case, the robber does not have key, can't open latent lock.

Latent lock (4) is installed on the dividing plate (8) in the said structure, and dividing plate (8) is welded in the channel-section steel the inside.

According to owner's needs, second latent lock (9) also can be installed on plate washer (3), making has two latent locks on the protection box.If like this, two latent keys must be opened simultaneously, just can push baffle plate (3) open.Latent lock (9) differs 90 degree with the direction of latent lock (4) lockhole.Certainly sense of direction, the feel during robber's hook lock is inequality again, has more increased the difficulty that the robber unblanks.

In order to open the door conveniently, if in the family people is arranged at ordinary times, can be with latent lock, have only that the man and wife gos out in pairs, unmanned guard in the family, just or evening when very dangerous with latent lock.Need careful key to fall in the room when unblanking, on one's body the most handy cord ties up to key.
