Description
A kind of smoke alarm test bar belongs to the detecting instrument technical field, relates in particular to the proving installation technical field to the Smoke Detection instrumental sensitivity.
Along with the continuous development that modern city is built, public places such as hotel, restaurant, office building must be provided with safety devices against fire, are in intact and sensitive duty all the time for making smoke alarm, and safety supervision department carries out regularly or irregularly detecting to it.
Existing detection method is to take ladder or chair pad underfoot again after lighting cigarette by the testing staff, carries out the sensitivity of detection alarm device near smoke alarm, and working strength is big, and efficient is low.
The purpose of this utility model provides a kind of easy and simple to handle, and is in light weight, smoke alarm test bar easy to carry.
The purpose of this utility model is achieved in that a kind of smoke alarm test bar, form by blast main, air duct, flexible air duct, bowl-type cover, battery case, fan etc., flexible air duct front end is connected with the bowl-type cover by special shaped screw bolt, its rear end links to each other with toe-in joint screw thread, prenex joint right-hand member is equipped with burns incense and the dust stratification tube, and the prenex joint right-hand member outside is threaded with air duct; Front end transmitted beam joint the blast main is fastenedly connected with air duct, and air intake is responsible for inwall and is welded with fan fixed head and battery case fixed head, and fan attachment and battery case are provided with pilot lamp and switch on blast main's outer wall respectively.
Its feature of smoke alarm test bar also is to have through hole on the toe-in joint, and as the passage of smog, prenex joint right-hand member is provided with the minor thread hole and the placement hole of burning incense, and is convenient to fixedly burn incense; On the dust stratification tube, be provided with air inlet.
When electric fan is worked, make wind enter the dust stratification tube, blow the smog of burning incense to the bowl-type cover, thereby the sensitivity of smoke alarm is detected.The utility model is simple in structure, and is easy and simple to handle, in light weight, easy to carry.
In conjunction with the accompanying drawings, embodiment is described.
Accompanying drawing is the smoke alarm structural representation.
Among the figure, 1 bowl-type cover, 2 special shaped screw bolts, 3 flexible air ducts, 4 prenex joints, 5 air ducts, 6 burn incense, 7 dust stratification tubes, 8 bundle joints, 9 fans, 10 fan fixed heads, 11 pilot lamp, 12 switches, 13 blast mains, 14 battery cases, 15 ajutage end caps, 16 battery case lids, 17 battery case fixed heads, 18 gib screws.
Unload the ajutage end cap 15 4 joint 1.5V dry cells of in battery case, packing into, the battery case lid 16 of screwing on, load onto and burn incense and fixing with gib screw 18, light burn incense after, install dust stratification tube 7, with restrainting fixedly blast main 13 of joint 8, and connecting flexible air duct 3, the ajutage end cap 15 of screwing on is pressed switch 12, energized, pilot lamp 11 is bright, and fan 9 begins to rotate, and wind enters bowl-type cover 1 by dust stratification tube 7 air inlets 6 the smog through hole by toe-in joint 4 of will burning incense, bowl-type cover 1 near smoke alarm, can be detected smoke alarm.The testing staff can be according to the length of the height free adjustment smoke alarm test bar on roof.
