Description
The utility model relates to a kind of audio alert pull-bar type self-opening door that is used as the fire escape door.
In recent years, the fire incident of China constantly takes place, and has brought serious loss for the country and people's property, and one of not only a large amount of property ash is most, and has how many people to be buried among fire.The heavy injures and deaths of the personnel that fire causes, mostly be because after the fire generation, be locked or seal as the access door of evacuating usefulness, people are difficult to open rapidly for the moment flurried, crowded reaching in the fire smoke dark, withdraw the scene fast, under normal condition at ordinary times, do not allow personnel often to come in and go out again and door lock need be closed.
The purpose of this utility model is exactly a kind of audio alert pull-bar type self-opening door that will propose in order to solve the existing problem of above-mentioned fire escape door, personnel outdoors can not at will swarm into because of door lock closes, the personnel of the inside run into fire or other emergency, human body is handspike at a touch, door is opened automatically, transfers to the safe place fast, under usual situation, personnel near or pass through by force, phonetic alarm device send advice away from sound or warning.
The purpose of this utility model is achieved in that a kind of audio alert pull-bar type self-opening door, it is by door leaf, doorframe, handspike mechanism and phonetic warning system constitute, mainly comprise by the base plate that is fixed on the door leaf, fixed support is housed on the base plate, be with locking bar in the support, the locking bar middle part is with the compression spring, one end of compression spring is blocked by support, the other end is fixed by the back-up ring that is enclosed within on the locking bar, the two ends of close locking bar are by an end of bearing pin joint angle type lever, the other end of angle type lever connects handspike by bearing pin and forms handspike mechanism, and with handspike mechanism corresponding doorframe on phonetic warning system is housed, phonetic warning system is by Infrared Detectors, phonetic alarm device, push rod, contact and compression spring set become.When Infrared Detectors finds to have artificial nearly self-opening door, phonetic alarm device sends voice suggestion and advises away from sound, if pass through by force, the pull-bar type self-opening door sends alarm sound when opening, prompting monitoring personnel adopt an effective measure, and when fire or other emergency took place, human body promoted or runs into handspike, door is opened automatically, transfers to the safe place fast.
The utility model is simple in structure, makes easily, does not change original structure, when breaking out of fire or other emergency, people are as long as outwards promote or run into handspike, and thrust passes to angle type lever, drive locking bar toward moving left, break away from doorframe, door is opened rapidly, and as no special circumstances, artificial promotion handspike deserts one's post, phonetic alarm device gives a warning, and reminds the relevant personnel to go to processing.This door is applicable to emergency exits such as workshop, workshop, shop, assembly hall and public place.
Below in conjunction with drawings and Examples the utility model is illustrated in detail.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model structural representation;
Fig. 3 connects schematic diagram for the utility model locking bar and push rod bump.
Among the figure: 1, door leaf; 2, handspike; 3, compression spring; 4, back-up ring; 5, angle type lever; 6, doorframe; 7, locking bar 8, base plate; 9, support; 10, bearing pin; 11, push rod; 12, contact; 13, compression spring; 14, phonetic alarm device; 15, Infrared Detectors; 16, lead.
Shown in Fig. 1～3, a kind of audio alert pull-bar type self-opening door, it is by door leaf (1), doorframe (6), handspike mechanism and phonetic warning system constitute, it is characterized in that by the base plate (8) that is fixed on the door leaf (1), fixed support (9) is housed on the base plate (8), be with locking bar (7) in the support (9), be with compression spring (3) in the centre of locking bar (7), one end of compression spring (3) blocks support (9), the other end has the fixedly back-up ring (4) that is enclosed within on the locking bar (7), the two ends of close locking bar (7) are by an end of bearing pin (10) joint angle type lever (5), the other end of angle type lever (5) connects handspike (2) by bearing pin (10) and forms handspike mechanism, and with the corresponding doorframe of handspike mechanism (6) on phonetic warning system is housed, phonetic warning system is by the Infrared Detectors (15) that is contained in doorframe (6) top, install on the wall or the phonetic alarm device of janitor's room (14) and be contained in doorframe (6) and go up the push rod (11) corresponding with locking bar (7), compression spring (13), contact (12), lead (16) interconnects composition.Under usual situation, locking bar (7) is stuck on the doorframe (6) the one end under the effect of compression spring (3), and the push rod (11) upward corresponding with being contained in doorframe (6) collided and connect, and pins door leaf (1).When Infrared Detectors (15) is found the people is arranged near self-opening door, connected phonetic alarm device (14) send voice suggestion advise away from sound, when fire or other emergency generation, when human body needs only promotion or runs into handspike (2), thrust passes to angle type lever (5), lever (5) drives locking bar (7) toward moving left, be stuck in doorframe (6) and go up corresponding locking bar (7) the end disengaging doorframe (6) that connects that bumps with push rod (11), door is opened fast, safe transfer, simultaneously, it is corresponding with its locking bar (7) end that to bump the push rod (11) that connects protruding under the effect of compression spring (13), its contact (13) is collided, and lead (16) is connected, and connected phonetic alarm device (14) sends alarm sound, the prompting monitoring personnel adopt an effective measure, if any the artificial handspike of pushing and shoving, open door and desert one's post, carry out necessary criticism and education.
