Embodiment
As Fig. 1, shown in Figure 2, hand crank transmission device of the present invention comprises wind 1, rotating shaft 9, housing 2 and be installed in worm gear 3 in the housing 2, worm screw 4 and worm screw seat 5, worm screw 4 two ends are provided with worm screw seat 5, worm gear 3 is in transmission connection with worm screw 4 teeth, wind 1 is located in the set square hole in worm screw 4 ends, worm gear 3 is provided with output shaft 31, rotating shaft 9 links to each other with output shaft 31, worm gear 3 is provided with trip count pin 6, the worm gear 3 other trip count wheels 7 that are in transmission connection with trip count pin 6 that are provided with, trip count wheel 7 is provided with limiting tooth 71, trip count wheel 7 links to each other with elastic pressuring clamping device 8 on being installed in housing 2, elastic pressuring clamping device 8 can be stablized trip count wheel 7, and it can be rotated when being stirred by trip count pin 6, can make its nonvoluntary rotation again.The moving circle of worm gear 3 revolutions, trip count pin 6 is stirred trip count wheel 7 and is rotated a tooth position, when turning to the position of limiting tooth 71, trip count pin 6 limited teeth 71 withstand, trip count wheel 7 can not rotate again, thereby worm gear 3 and output shaft 31 can not rotate again, reach spacing purpose.In the present embodiment, the set worm screw seat 5 in worm screw 4 two ends adopts the ABS material, and has the groove structure that is used to install lubricating grease, can obtain good lubricating, and operation is smooth.Worm screw 4 is 7 with the velocity ratio of worm gear 3, and worm screw 4 is 3 worm screws, the transmission efficiency height.The lead-angle of worm screw 4 is 5.285 °, and self-locking is reliable.Rotating shaft 9 one ends are provided with first carriage 91 that links to each other with output shaft 31, the other end is provided with second carriage 92, be provided with torque spring 93 in the rotating shaft 9, torque spring 93 1 ends link to each other with second carriage 92, the other end links to each other with tray 94 in being located at rotating shaft 9, torque spring 93 is used for balanced load, and it is more laborsaving that hand crank transmission device is used.As Fig. 3, Fig. 4, shown in Figure 5, output shaft 31 is a Hexagon with the cross section of worm gear 3 connecting ends, with the cross section of first carriage, 91 connecting ends be quadrilateral, can adjust the initial position of rotating shaft 9 when mounted more accurately.
Below in conjunction with roll-up window working principle of the present invention is described: by wind 1 input torque, transfer torque to rotating shaft 9 through worm screw 4, worm gear 3 and output shaft 31, the rotation of rotating shaft 9 drives the roll-up window switch.In the using process, wind 1 every drive worm screw 4 is rotated seven circles, worm gear 3 rotates a circle, trip count pin 6 is stirred trip count wheel 7 and is rotated a tooth position, and when turning to the position of limiting tooth 71, trip count pin 6 limited teeth 71 withstand, trip count wheel 7 can not rotate again, thereby worm gear 3 and output shaft 31 can not rotate again, reach the purpose of the rotating distance of control rotating shaft 9, prevent that curtain from surpassing upper limit and causing damage.Can control the length of total kilometres by the initial tooth position that trip count pin 6 and trip count wheel 7 is set.Torque spring 93 in the rotating shaft 9 comes balanced load, and when curtain is opened, when curtain all twisted in the rotating shaft 9, torque spring 93 was in free state; When rotating shaft 9 is rotated, when curtain is closed, curtain is because gravity loads a moment of torsion in rotating shaft 9, this moment, torque spring 93 1 ends rotated with rotating shaft 9, the other end is motionless, thereby produces torsional deflection, in rotating shaft 9, load one with the opposite moment of torsion of curtain gravity generation torque direction, thereby can weigh by balance gate, hand crank transmission device uses more laborsaving.
