CN2295829Y - Lateral and vertical linking locked safety door - Google Patents

Abstract

The utility model relates to a lateral and vertical linking locked safety door, which belongs to a safety door class, and using a safety door leaf composed of a door leaf frame, a face plate, a back plate, a reinforcing rib, an insulation filling layer, an observation window, a side lock mechanism, a rolling gate lock mechanism, an upper and a lower door shafts and the inserting posts of a hinging edge as basis. The upper and the lower vertical bolts of rolling gate lock mechanism are respectively connected with a lateral bolt linking mechanism composed of a rectangular reversing rod, a pivot shaft, lateral bolts and a guide sleeve. The lateral and vertical linking locked safety door conveniently and effectively increases locking points and increases the safety of the safety door through the linking mechanism, and the upper and the lower inserting posts of the hinging edge of the door leaf are changed into hook shapes from column shapes so that the utility model more effectively increases the safety.

Description

Anyhow the antitheft door leaf of linkage locking

The utility model belongs to antitheft class.

Not stolen for the property that prevents family, security door is adopted by huge numbers of families.Present antitheft door leaf is mainly by Door leaf frame, panel, backboard, reinforcing rib, insulation packing course, observation port, limit latch mechanism, coil brake lock mechanism, the inserting column on door-hinge, hinged limit is formed up and down.After door leaf cut out, the insertion of vertical cutting pin was gone up in the lower door frame about the coil brake lock mechanism of door leaf passed through, and the lock seaming frame is opened in the doorframe on limit by the dead bolt insertion of limit latch mechanism, and two doorframe inserting columns inserted in the doorframe about hinged side was passed through.Though this door leaf is locked doorframe at four direction, still has unsafe factor, as long as limit lock brill is ruined, this limit is then out of control as the lock seaming frame, and the door leaf ratio is easier to be pried open, the part so this door leaf safety still has some deficits.

The purpose of this utility model is: provide a kind of safety the higher security door of linkage locking anyhow.Increase the security performance of security door.

Technical measures of the present utility model are: based on by Door leaf frame, panel, backboard, reinforcing rib, insulation packing course, observation port, limit latch mechanism, coil brake lock mechanism, the antitheft door leaf formed of the inserting column on door-hinge, hinged limit up and down; On the pin of vertical cutting up and down of coil brake lock mechanism, be connected with the lateral pin link gear that a reversing bar by right angle type, hinge, horizontal latch and fairlead are formed respectively.

Antitheft door leaf of the present utility model, when with vertical vertical cutting pin up and down last lower door frame being locked by volume lock pin mechanism, two lateral pins of lateral pin link gear lock the lock seaming frame of doorframe simultaneously, and promptly having has increased locking point, and the good effect that has increased safety is arranged again.

Fig. 1 is a structural representation of the present utility model.Fig. 2 is a vertical view.

Drawing explanation and embodiment are described below: 8 is existing antitheft door leafs among the figure, by Door leaf frame, panel, backboard, reinforcing rib, insulation packing course, observation port, limit latch mechanism, coil brake lock mechanism 1 and 2, the doorframe inserting column 7 on door-hinge, hinged limit is formed up and down.The utility model is on the basis of above-mentioned existing antitheft door leaf; On the upper and lower latch 2 of coil brake lock mechanism, be connected with a lateral pin link gear that bar 3, hinge 4, horizontal latch 5 and fairlead 6 are formed that changes respectively by right angle type.After door leaf cuts out, the hinged side of door leaf is gone in the doorframe by two doorframe inserting columns 7 up and down, the lock seaming frame of door leaf is inserted by the dead bolt of limit latch mechanism and is opened in the doorframe on limit, the coil brake lock mechanism of door leaf passes through vertical cutting pin 2 insertions up and down goes up in the lower door frame, and vertical cutting pin 2 is when inserting doorframe, in the also laterally inserted doorframe of 5 while of horizontal latch of link gear up and down, so not only increased locking point, even and if when robber person's brill had been ruined the limit lock, door leaf still can not pried open yet, and has increased very big safety.

In order to increase the bigger safety of door leaf, inserting column up and down 7 that will existing door leaf 8 hinged limits, by the garden cylindricality, change the sheet hook-type into, when door leaf cuts out, sheet hook 7 not only inserts in the doorframe, but also be hooked in the doorframe, door leaf 8 and doorframe can't be pried open on hinged limit.Bigger safety is arranged.

Claims (2)

1, a kind of interlock anyhow locks the security door fan, by Door leaf frame, panel, backboard, reinforcing rib, insulation packing course, observation port, limit latch mechanism, coil brake lock mechanism, the inserting column on door-hinge, hinged limit is formed up and down, it is characterized in that: on the pin of vertical cutting up and down of coil brake lock mechanism, be connected with the lateral pin link gear that a reversing bar by right angle type, hinge, horizontal latch and fairlead are formed respectively.

2, by the described antitheft door leaf of claim 1, it is characterized in that: the inserting column up and down on the hinged limit of door leaf is the sheet hook-type.
