Abstract

The utility model relates to an against and pressing type door opening device; the door body is provided with a lock tray, a bolt and a pulling spring; the bottom of the lock tray is a convex table which is movable connected with the moving pole; the moving pole limits the rotating of the lock tray and the moving pole is inserted in the sliding passage; the bottom is a sliding block which is connected with the relay; the against and pressing plate is pressed on the opening pole in the middle part of the door body; one end of the opening pole is cuniform positioned in the door to form an exercising pair with the sliding block; when the pressing plate is pressed and the opening pole moves inward, the cuniform and the sliding block are linked to drive the moving pole to separate with the convex table to release the lock tray; the energy storing spring pulls the bolt, the door body is opened and the opening function is finished. The against and pressing plate is positioned in the middle of the door to bring convenience to the touching and have a large pressing area; the door can be opened when the evacuation workers contact and press the door body; therefore the utility model speeds up the evacuation time and ensure the safety of the workers.

Description

The tight opening device of pressured formula door

Technical field:

The utility model relates to the tight opening mechanism of a kind of egress door, and the tight opening device of especially a kind of pressured formula door belongs to an opening structure technical field.

Background technology:

The manually opened mechanism of existing egress door generally is located at a side on doorway, in case of emergency move depression bar and open egress door, but when emergency takes place, the scene is often relatively more chaotic, the evacuation personnel can not find manually opened mechanism opening egress door exactly, postpone to open the time of egress door thus, caused serious consequence easily.

Summary of the invention:

The utility model discloses the tight opening device of a kind of pressured formula door, and opening mechanism is located at the middle part of a body and touches easily, as long as the pressured egress door of human body can be opened door rapidly, finishes the evacuation purpose.

Technical solution of the present utility model is as follows: an end of pressured plate is hinged on a body middle part, and be pressed on the all-or-nothing piece, the rear end of all-or-nothing piece is that the slide block of wedge and slideway lower end constitutes kinematic pair, stage clip is located at the bottom of pressured plate, in the door body, also be provided with lock collar and dead bolt, driving lever is flexible connection by slideway and lock collar, the bottom of driving lever is provided with the contact interlock of slide block and relay, pushing pressured plate presses all-or-nothing piece and makes slide block to bottom offset by its rear end wedge, lock collar is released, dead bolt resets under the effect of extension spring, and the door body can be opened.

Good effect of the present utility model is: adopt pressured board-like unlatching door locking structure, pressured plate area is very big, is located at a body middle part and touches conveniently, as long as the evacuation personnel touch pressured to the door body, egress door can easily be opened, and has accelerated egress time, has guaranteed personal security.

Description of drawings:

Fig. 1 is the utility model structure principle chart.

The specific embodiment:

According to shown in Figure 1, device has lock collar 11 in the door body 1, which is provided with dead bolt 12 up and down, 9, two ends are connected with extension spring 13 respectively, 8, the bottom of lock collar 11 is that boss 14 can constitute flexible connection with driving lever 15, rotation by driving lever 15 restriction lock collars 11, driving lever 15 is embedded in the slideway 16, its bottom is a slide block 18, and be connected with the contact 4 of relay 2, back-moving spring 3 is enclosed within on the contact 4, also is provided with release link 10 on the lock collar 11, pressured plate 7 is hinged on middle part, a body 1 surface and is pressed on the all-or-nothing piece 6, stage clip 5 be located at pressured plate 7 below, an end of all-or-nothing piece 6 is that wedge 17 is installed in the body 1 and constitutes kinematic pairs with slide block 18, when pressured plate 7 pressings, all-or-nothing piece 6 moves inward, while wedge 17, slide block 18 interlocks drive driving lever 15 displacements and break away from the boss 14 of lock collar 11 and discharge lock collar 11, accumulation of energy extension spring 8,13 draw back

dead bolt

9,12, egress door body 1 is opened, and finishes open function.

Claims

1, the tight opening device of a kind of pressured formula door, in the door body, be provided with lock collar and locking bar, driving lever is flexible connection by slideway and lock collar, the bottom of driving lever is provided with the contact interlock of slide block and relay, it is characterized in that: an end of pressured plate is hinged on a body middle part, and be pressed on the all-or-nothing piece, stage clip is located at the bottom of pressured plate, and the rear end of all-or-nothing piece is that the slide block of wedge and slideway lower end constitutes kinematic pair.
