Abstract

A lock comprises a locking box and a locking latch, wherein the locking box comprises a shell with a nick opening on the lateral end face on the shell near the locking latch and a bolt with a hook, and the locking latch threads the nick and is partly arranged in the shell with the hook hitching the locking latch in locking state while the hook threads the nick and is partly arranged in the shell with the locking latch arranging on the outer side of the shell and also separating from the hook in the unlocking state, more applicable to be used in the condition of better sealing performance employed on the doors with pressure difference between an inner chamber and an outer chamber, further more applicable to be used in a double acting door and a translatory door thereby having a more extensive using range, having the advantage of using more conveniently for further ejecting the door automatically by lolling out the bolt when locking.

Description

Lock

Technical field

The utility model relates to a kind of lock, particularly is installed in the lock on the door.

Background technology

In the prior art, the lock of installing on the door generally comprises lock box and the locked groove that is positioned at the sidepiece of described lock box, usually lock box all is that the width that is parallel to door is provided with, locked groove then is arranged in the body of wall or cabinet relative with described lock box, described lock box comprises housing and dead bolt, and when this lock locking, described dead bolt is in the locked groove that extend into outdoors on the body of wall is stretched out in the side, and be against on the sidewall of locked groove, door is blocked at opening direction; When unblanking, by the transmission mechanism that is arranged in the housing dead bolt is return in the door, thereby door is opened.

Yet if between the inner room of door and the mistress when existing bigger pressure differential, as the door on the purifying box in the hull, even the control transmission mechanism is drawn back dead bolt, pressure still makes dead bolt push against on the sidewall of locked groove, and can't return smoothly in the door, must dead bolt be left in the just recoverable door of sidewall of locked groove earlier with defeating door, this brings constant greatly to the user; Particularly for the electronic lock by circuit control, it only depends on and offers fixing release pulling force of dead bolt and carry out release, and this pulling force is all smaller and can't under the environment of pressure dead bolt be retracted in the lock box usually.

Summary of the invention

The purpose of this utility model provides a kind of lock, also can open smoothly and locking when there is pressure differential in it between inner room and mistress.

The technical solution of the utility model is: a kind of lock, comprise lock box and the snap close that is positioned at the side of described lock box, described lock box comprises housing, is arranged at dead bolt in the described housing movably, described housing has breach near on the side end face of described snap close, described dead bolt phase pivot is rotationally connected with on the described housing, and has hook portion on the described dead bolt, when described lock is in the lock state, described snap close passes described breach and part is positioned at described housing, and described hook portion is hooked described snap close; When described lock was in released state, described hook portion passes described breach and part is stretched out described housing, and described snap close is positioned at outside the described housing, and described hook portion and described snap close are separated.

Also be provided with location-plate on the described housing rotationally, have locating slot on the described location-plate, also have fastener on the described dead bolt, when described lock was in the lock state, described fastener was stuck in the described locating slot; When described lock was in released state, described fastener left described locating slot.

Also be provided with the shake-up piece in the described housing movably, when described lock was in the lock state, described shake-up piece and described location-plate were separated; When described lock was in released state, the end of described shake-up piece pushed against described location-plate.

Also be set with electromagnet on the described housing, the bottom that is positioned at described dead bolt on the described housing also is provided with touch switch, described touch switch and described electromagnet are electrically connected, described shake-up piece flexibly passes the inner chamber of described electromagnet, the top of described touch switch flexibly is provided with touch panel, described touch switch has the two states of switching on and off, when described lock is in the lock state, described dead bolt is against on the described touch panel, and described touch switch is in on-state; When described lock was in released state, described dead bolt left described touch panel, and described touch switch is in off-state.

Be provided with torsion spring between described dead bolt and the described housing.

Also be provided with limited post on the described housing, described limited post is positioned at the side of described dead bolt away from described breach.

The utility model compared with prior art has following advantage: the utility model hooks or leave snap close by described latch hook realizes locking or release, can not be subjected to the inner room of door and the influence of the pressure differential between the mistress, therefore to be more suitable for the sealing situation than traditional locks better for the utility model, and inner room, mistress exist the door of pressure differential to go up use, it can be applicable to sliding door and parallel-moving type door simultaneously in addition, and range of application is more extensive; Because dead bolt flexibly is arranged on the opening direction of door, so when unblanking, dead bolt stretches out can and not needed manually door to be pulled out with the automatic ejection of door again, very convenient in the use.
