Summary of the invention
The purpose of this utility model is: provide a kind of infrared induction self closing door.Should be able to realize: without the need to personnel on site's operation, by infrared induction personnel, vehicle pass-through object and automatically air door is opened (or close), thus save manpower, the function of reduction security risk.
In order to realize above-mentioned object, the utility model ties contact by infrared opposite-radiation inductor, electric pushrod device, steel cable, pulley, doorframe, door leaf, linkage, balancing weight composition infrared induction self closing door, comprise: electric pushrod device (1), push rod device support (2), connecting pin (3), 1# steel cable (4), 1# supporting point sliding wheel support (5), 1# fulcrum pulley (6), doorframe (7), tie point (8), right door leaf (9), rectangular connecting rod (10), left-hand door page (11), hinge (12), balancing weight (13), 2# steel cable (14), 2# supporting point sliding wheel support (15), 2# fulcrum pulley (16), be flexibly connected point (17), 3# fulcrum pulley (18), crossbeam hole (19), tie point (20), 7 font connecting rods (21), crossbeam (22), infrared opposite-radiation inductor tie point (23), doorframe (24), connecting hole (25).
Its architectural feature is: electric pushrod device (1) is fixed on support (2), its one end is provided with infrared opposite-radiation inductor tie point (23), the other end has the connecting pin (3) of 1# steel cable (4), fixing 1# supporting point sliding wheel support (5) is settled between electric pushrod device and doorframe (7), 1# fulcrum pulley (6) is fixed on its top, doorframe (7), and crossbeam (22) is fixing welds and be fixed on edge, tunnel (24), right door leaf (9) is connected with doorframe (7) by hinge, tie point (8) is welded with in the middle part of it, upper end is welded with tie point (20), top is welded with 7 font connecting rod (21) one end, the 7 font connecting rod other ends have connecting hole (25), hole (19) is had in the middle part of crossbeam, the left end in hole fixes 3# fulcrum pulley (18), doorframe (24) is flexibly connected with left-hand door page (11) by hinge (12), welded pulley support (15) is fixed on its top, support is fixedly connected with 2# fulcrum pulley (16), left-hand door page (11) upper weld is flexibly connected point (17), rectangular connecting rod (10) is by being flexibly connected point (17), connecting hole (25) is flexibly connected.
1# steel cable (4) one end is fixedly connected on the connecting pin (3) of electric pushrod device one end, the other end is fixedly connected with the tie point (8) on right door leaf through 1# fulcrum pulley (6), 2# steel cable (14) one end is fixedly connected with right door leaf upper end tie point (20), the other end is through the hole on crossbeam, through 3# fulcrum pulley (18), after 2# fulcrum pulley (16), be fixedly connected with balancing weight (13).
Because the utility model is infrared induction self closing door, personnel are not needed to handle, when infrared opposite-radiation inductor senses that people and Che are away from during close to air door, inductor is passed to electric pushrod device by knot contact and is stretched, contracting signal, electric pushrod device is stretched in execution, during contracting action, strain or loosen 1# steel cable, the power of tension 1# wire rope is greater than the gravity of balancing weight, 1# wire rope is just strained right door leaf and is outwards opened, right door leaf rotates and drives 7 font link rotatable simultaneously, 7 font connecting rods promote rectangular connecting rod simultaneously, again because rectangular connecting rod is flexibly connected 7 font connecting rods by tie point, left-hand door page, rectangular connecting rod outwards promotes left-hand door page and is opened by left-hand door page, simultaneously, 2# steel cable fixing on the tie point of right door leaf upper end outwards rotates with right door leaf and is improved by balancing weight by sliding, door is opened, when sensing people and Che leaves certain distance, electric pushrod device performs the instruction of stretching, now, power on 1# wire rope is less than balancing weight weight, namely balancing weight strains 2# wire rope, by pulley, right door leaf is inwardly closed, right door leaf inwardly rotates simultaneously, drive 7 font supports, rectangular connecting rod, left-hand door page rotate thus by a left side, right two door leafs are inwardly closed.
Accompanying drawing explanation.
Fig. 1 is the utility model overall appearance allocation plan.
In above-mentioned figure: 1, electric pushrod device 2, push rod device support 3, connecting pin 4, 1# steel cable 5, 1# supporting point sliding wheel support 6, 1# fulcrum pulley 7, doorframe 8, tie point 9, right door leaf 10, rectangular connecting rod 11, left-hand door page 12, hinge 13, balancing weight 14, 2# steel cable 15, 2# supporting point sliding wheel support 16, 2# fulcrum pulley 17, be flexibly connected point 18, 3# fulcrum pulley 19, crossbeam hole 20, tie point 21, 7 font connecting rods 22, crossbeam 23, infrared opposite-radiation inductor tie point 24, doorframe 25, connecting hole.
Detailed description of the invention.
Enumerate preferred embodiment below in conjunction with accompanying drawing to be described in more detail the utility model.
Embodiment.
The present embodiment is all the air door combination of metal material: comprise electric pushrod device 1, push rod device support 2, connecting pin 3, 1# steel cable 4, 1# supporting point sliding wheel support 5, 1# fulcrum pulley 6, doorframe 7, tie point 8, right door leaf 9, rectangular connecting rod 10, left-hand door page 11, hinge 12, balancing weight 13, 2# steel cable 14, 2# supporting point sliding wheel support 15, 2# fulcrum pulley 16, be flexibly connected point 17, 3# fulcrum pulley 18, crossbeam hole 19, tie point 20, 7 font connecting rods 21, crossbeam 22, infrared opposite-radiation inductor tie point 23, doorframe 24, connecting hole 25.
Embodiment 2.
Above-mentioned example is work like this.
After infrared opposite-radiation device starts, left and right two fan door is in closed condition, when infrared opposite-radiation device detect people and Che be close to certain distance time, namely electric pushrod device is started, push rod is pulled back 1# wire rope, now, pulling force suffered by 1# wire rope is greater than the weight of balancing weight and the power suffered by 2# wire rope, namely right door leaf is outwards pulled open by the wire rope tie point on 1# fulcrum pulley and right door leaf by wire rope, when right door leaf outwards rotates, drive 7 font connecting rods, because of strip connecting rod and 7 font connecting rods, tie point on left-hand door page is for being flexibly connected, 7 font connecting rods promote strip link motion, and on left-hand door page, be flexibly connected thrust outside equally suffered by point.Therefore, left-hand door page is also outwards opened, when infrared opposite-radiation device detect people and Che away from door certain distance after, namely electric pushrod device is started, push rod is protracted, now, pulling force suffered by 1# wire rope is less than the gravity of balancing weight suffered on 2# wire rope, balancing weight strains 2# wire rope well, namely 2# wire rope passes through 2#, right door leaf inwardly pulls by the fixed connection point of 3# fulcrum pulley and right door leaf upper end, right door leaf inwardly moves, 7 font connecting rods are driven when being both, rectangular connecting rod, left-hand door page motion and door is fanned in left and right two inwardly close, operatorless automatic opening and closing door is completed with this.
