Preferably, the automatic alarm prompt door closing control device (9) is provided with a time relay (13) which can control the closing time of the door leaf according to the self-setting time.
Preferably, the alarm prompting device (12) can adopt a buzzer or an audible and visual alarm.
Has the advantages that:
1. the door leaf is automatically closed by the arrangement of the special spring of the automatic closing hinge and the shaft.
2. Through automatic alarm suggestion closing door controlling means's setting, effective management and control in time avoids the conflagration hidden danger.
3. The outer side of the special spring is covered by a steel pipe with the thickness of 3mm, and the steel pipe is painted with fireproof paint or is internally filled with rock wool, so that the baking resistant time under the condition of high temperature of fire is effectively blocked, and the design requirement of a fireproof function is met.
4. Through the setting of time relay, can set up the closing time of door leaf in a flexible way, prevent to force the potential safety hazard of opening and bringing for a long time.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is the structure schematic diagram of the automatic alarm prompting door closing control device of the utility model.
In the figure: the method comprises the following steps of 1-a door frame, 2-a door leaf I, 3-a door leaf II, 4-an opening handle I, 5-an opening handle II, 6-an automatic closing hinge, 7-a monitoring probe I, 8-a monitoring probe II, 9-an automatic alarm prompt door closing control device, 10-a photoelectric sensor, 11-a converter, 12-an alarm prompt and 13-a time relay.
Detailed Description
The technical scheme of the embodiment of the utility model is further described with reference to the attached figures 1-2 in the embodiment of the utility model, and the automatic door-closing alarm prompt fireproof safety door comprises a door frame (1), a door leaf I (2), a door leaf II (3), an opening handle I (4), an opening handle II (5) and an automatic closing hinge (6), monitor probe I (7), monitor probe II (8), automatic alarm suggestion closing door controlling means (9) constitute, door frame (1) is connected door leaf I (2) respectively through self-closing hinge (6), door leaf II (3) outer both sides, door leaf I (2) and door leaf II (3) are provided with respectively to the division punishment and are opened handle I (4), open handle II (5), be provided with monitor probe I (7) on door leaf II (3), monitor probe II (8), embedded in door leaf II (3) of automatic alarm suggestion closing door controlling means (9).
The automatic alarm prompt door-closing control device (9) comprises a photoelectric sensor (10), a converter (11), an alarm prompt (12) and a time relay (13).
A special high-strength spiral spring is arranged on an inner shaft of a hinge of the automatic closing hinge (6), and is matched with the shaft by the physical principle of rotating torque force, and a strengthening positioning device is arranged according to the strengthening principle of a mechanical clock pulling strip.
