Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1-8: master arm 201 strings are in rotating shaft 8; Crank 208 connects firmly on reducer output shaft 207; Connecting rod 205 is connected by bearing pin 206 with crank 208; Connecting rod 205 is by being connected with master arm 201 with pin 204 that master arm 201 connects firmly; Speed reduction unit base 4 utilizes screw to be connected with base 5; Reducing motor 3 utilizes screw to be connected with reducing motor base 4; The motor that described reducing motor promptly links to each other with speed reduction unit, reducing motor base 4 connect firmly on fan door base 5; A fixedly connected microswitch 106 on the fan door arm; The fan door wing 101 is connected by hinge 104 with fan door arm 102, and the scope of activities of the spacing guide pillar 108 restriction fan door wings 101 makes the fan door wing 101 to rotate in the certain angle scope near fan door arm 102.Torsion spring caging bolt 6 screws on the projection of fan door arm 102, and fan door arm 102 connects rotating shaft 8, and can 8 rotate around the shaft; Bolster 9 connects firmly with fan door arm 102; Torsion spring 7 is enclosed within on the rotation axis 8, and torsion spring 7 one ends insert in the base 5, the other end rides on the torsion spring caging bolt 6; Microswitch is being fanned on the door arm 102 by screw retention; Two magnet steel 103 are separately fixed on the magnet steel seat of fanning on the door arm 102 111 and master arm 201 by screw; Electromagnet 202, and contacts with magneto-resistor 213 bottoms on master arm 201 by screw retention; Magneto-resistor 213 is connected with magneto-resistor seat 212 by threaded 214, and by the jump ring axial restraint; Magneto-resistor torsion spring 211 is enclosed within on the threaded 214, and by hexagonal nut 021, elastic washer 022 and plain washer 023 axial location; Magneto-resistor torsion spring 211 1 ends contact with magneto-resistor seat 212, and the other end is pressed on the magneto-resistor 213, and its elastic torque direction forces magneto-resistor 213 to rest between two magnet steel 103; Magneto-resistor seat 212 by interior hexagonal cylinder screw retention on master arm 201; On fan door arm 102, spring 109 is enclosed within on the spring guide pillar 107 and with spring base 105, fan door arm 102 and contacts spring base 105 by screw retention.
During work, reducing motor 3 drives crank 208, and by pin 206 drivening rods 205, described connecting rod 205 is by pin 204 traction master arms 201, and master arm 201 rotates around door-hinge 8.Because electromagnet 202 gets the electric effect of withstanding magneto-resistor 213 and overcoming magneto-resistor torsion spring 211 that protrudes upward, make magneto-resistor 213 around threaded 214 rotations, depart from magnet steel 203 axial location simultaneously and allow open-flux path.Magnet steel 103 was attracted each other with magnet steel 203 when master arm 201 was near fan door arm 102 thus, and fan door arm 102 is drawn by master arm 201, thereby drove fan door arm unitary rotation, realized the action of opening the door and close the door of fan door.
When outage, the withdrawal of electromagnet 202 dead electricity, magneto-resistor 213 is rotating under the driving of magneto-resistor torsion spring 211 between two magnet steel 103, magnetic circuit between two magnet steel 103 is obstructed, this moment, fan door arm 102 was not subjected to the control of master arm 201, and a direction of opening to the fan door under the driving of the answer moment of torsion that is produced by torsion spring 7 is rotated, and the fan door is opened.
Under the situation of energising, no matter fan door and be in which kind of state, when the fan door wing 101 is subjected to external force greater than spring 109 elastic force, the fan door wing 102 is to the direction rotation of fanning door arm 101 and close, touch microswitch 106 until the fan door wing 101, and then tripping magnet 211 power supplys, under the effect of magneto-resistor torsion spring 211 restoring forces, magneto-resistor 202 is returned between two magnet steel 103, and the blocking-up magnetic circuit; This moment, fan door arm 102 was not subjected to the control of master arm 201; fan door arm to the opening direction rotation, goes to bolster 9 and collides with base 5 under the twisting force of torsion spring 7, is limited in opening; thereby realization overload protection, fan door 101 just can be opened and be unlikely to the bitterly crowded or crowded passenger that hinders.
