Description

A kind of bidirectional opening safety door

The utility model relates to building and vehicle.Safety door on the steamer is applicable to that especially dwelling house, warehouse, work about electric power chamber and visitors flowrate turnover are more, the used safety door in frequent public place.

Employed various classes are very single at present, mainly contain unidirectional opening, and drive into or leave, and also have or not edge sealing swinging door, sliding door.Unidirectional opening the door, as the meeting open inward indoor certain space that accounts for, and to external-open, as must earlier door being drawn back outward in the inlet chamber, it is indoor to be allowed for access, and when these doors as breaking out of fire, earthquake etc. were dangerous in addition, personnel were difficult to open the soonest and withdraw.Can open though swinging door is inside and outside, fatal shortcoming is that seal degree is relatively poor, and its safety is also not enough.

In order to solve the defective of above-mentioned safety door, the utility model purpose provides a kind of solution had both allowed user's inlet/outlet convenient, can not account for the interior space again, attractive in appearance, safe bidirectional opening safety door.

The utility model is finished in such a way: the side at door leaf is equipped with several movable axle sleeves from top to bottom, main shaft be fixed on the corresponding doorframe of the movable axle sleeve of door leaf on, two connecting bushing, doorframe is installed main shaft one side, low outer high in being designed to, door leaf can inside and outsidely be opened freely, suitable position at door leaf is installed Safety door lock, on on the Safety door lock drive door leaf, in, following flexible couple axle and master latch bar, last, in, design has a groove on the side door frame of flexible couple axle correspondence down, match with the master latch bar, when last, in, down flexible couple axle drives the master latch bar, be master latch bar indentation door leaf one side or spring in the groove of doorframe, door just can close or open, and on last lower door frame, respectively design the flexible automatically edge sealing tongue bars of a semicircle, thereby guaranteed that the two-way of door leaf freely open and seal request.

The utility model has the advantages that: one, door leaf can arbitrarily inside and outsidely be opened, and especially can save the interior space; Two, open convenient, fast, safety, good airproof performance.

Below in conjunction with accompanying drawing the utility model is further described below.
