Description

Anti-prizing safety door

Technical field

The utility model relates to anti-theft safety door, particularly a kind of Anti-prizing safety door.

Background technology

Anti-theft safety door of the prior art generally comprises doorframe, be connected through the hinge the door leaf on doorframe and to be arranged on door and can to coordinate the lockset controlling door leaf afterwards and open or close with doorframe; Be easy to be pried open because door leaf is exposed to lockset outside doorframe, although some prized up-proof door door leafs are enclose by doorframe, but due to its door leaf being exposed to outside doorframe below, still the position of lock point is easily found to destroy, thus there is stolen event, so the safety of the prized up-proof door of this structure and mechanical strength or low, the safety of indoor article still cannot be ensured.

Summary of the invention

The purpose of this utility model is to provide while door leaf encases by a kind of doorframe, the Anti-prizing safety door that the mechanical strength of lockset is higher.

The utility model is achieved through the following technical solutions, i.e. a kind of Anti-prizing safety door, comprise the doorframe be made up of upper ledge, lower frame and two munnions, the door leaf be connected through the hinge on a munnion, be arranged on door leaf and lock by side chain tongue and another munnion the automatic locking master lock body a little coordinated; It is characterized in that: inside two munnions of described doorframe, be provided with groove, the width of door leaf is greater than horizontal range between two groove groove tops, be less than horizontal range between two groove bottom lands; Door leaf is moved horizontally to when its both sides are arranged in described groove and is in cut out, and door leaf is in unlatching to during the moving horizontally and make another side depart from the groove of munnion of door pivot; The dead bolt up and down of automatic locking master lock body respectively be connected locking bar one end and connect, when door leaf cuts out, connect the other end of locking bar under the drive of automatic locking master lock body, respectively be arranged on upper ledge lock a little and to be arranged on lower frame lower locks a little to coordinate and lock.

Further, described connection locking bar is provided with at least one inverted hook type side chain, described inverted hook type side chain comprises side chain point drive link, one end of this side chain point drive link is fixed on connection locking bar, the other end is tooth bar, rotate hanging scroll tooth with the side chain point in the corresponding side chain point box be arranged on munnion to engage, rotate by side chain point the side chain point ring lock tongue synchronous rotary that to drive when hanging scroll rotates and there is opening and realize rotating with side chain point mounting or the disengaging of hanging scroll.

Further, described hinge is stealthy blind hinge, and be right angle blocks, it is connected with the rotating shaft be arranged in munnion, and another side is connected with door leaf; Its opening angle is 0 ° ~ 180 °.

Further, what described right angle blocks was connected with door leaf is apart from adjustable design.

The advantage that the utility model has due to said structure is apparent: after door leaf cuts out, from outdoors, door leaf is in doorframe, makes burglar can not find origin of force completely, just cannot pry open door leaf, thus improve safety; Meanwhile, connect the mechanical strength that locking bar adds door up and down, further, add inverted hook type side chain on this basis, further increase safety; Stealthy blind hinge can opening angle be 0 ° ~ 180 °, makes door leaf also can open 0 ° ~ 180 °, improves practicality.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

See accompanying drawing, Anti-prizing safety door in figure, comprise the doorframe be made up of upper ledge 1, lower frame 20 and two munnions 4,27, the door leaf 3 be connected through the hinge on a munnion 4, be arranged on door leaf 3 and lock with another munnion 27 the automatic locking master lock body 17 a little coordinated by side chain tongue; Wherein: inside two munnions of described doorframe, be provided with groove, the width of door leaf is greater than the horizontal range between two groove groove tops, is less than the horizontal range between two groove bottom lands; Door leaf 3 is moved horizontally to when its both sides are arranged in described groove and is in cut out, and door leaf makes another side depart from the groove of munnion to moving horizontally of door pivot and is in unlatching; The dead bolt up and down 16 of automatic locking master lock body 17 respectively be connected locking bar one end and connect, when door leaf cuts out, the other end connecting locking bar respectively be arranged on locking of upper ledge and a little 12 lock with to be arranged on lower frame 20 lower and a little 19 coordinate and lock.

Connect described in this lethality on locking bar 15 and be separately installed with two inverted hook type side chains 13, described inverted hook type side chain 13 comprises side chain point drive link 21, one end of side chain point drive link 21 is fixed on and connects locking bar 15, the other end is tooth bar, rotate hanging scroll 25 tooth with the side chain point in the corresponding side chain point box 22 be arranged on munnion 27 to engage, rotate by side chain point side chain point ring lock tongue 26 synchronous rotary that to drive when hanging scroll 25 rotates and there is opening and realize rotating with side chain point mounting or the disengaging of hanging scroll 25.

Described hinge is stealthy blind hinge 2, and be right angle blocks, it is connected with the rotating shaft be arranged in munnion, and another side is connected with door leaf; Its opening angle is 0 ° ~ 180 °

In an embodiment, what stealthy blind hinge 2 was connected with door leaf is apart from adjustable design, and the interval of adjustable fan in doorframe is more safe and reliable, uses convenient.
