The course of work of the present invention：
A kind of adjustable low precision automatic closing door of the invention during the work time, when needing that door is made to be automatically closed, leads to
It crosses and rotates elastic adjusting bolt 65 gap between the passive tooth plate 62 in power limiting section 6 and active tooth plate 63 is made to increase, open
During door, drives driving gear 45 to rotate by shutdown Rocker arm 48, passive buffer gear cold 46 is driven by driving gear 45
Rotation, by, 47-, back and forth eccentric shaking tray 47 drives reciprocal rocker 44 to move back and forth, and passes through reciprocal rocker 44 and drives buffer shaft 422
It is slided in buffering sleeve 421, while platen 425, gasket 426 will be sealed by Packing spring 427 and are pressed in buffering sleeve 421
End makes to be sealed in buffering sleeve 421, preservation air that can be carefully, improves buffering effect, passes through and rotate deflation resistance tune
Section bolt 436 and intake resistance adjusting bolt 439 can change the inlet and outlet size of air in buffering sleeve 421, and then can be with
Change damping, while being rotated by the shaft of passive buffer gear cold 46, power steel wire 51 is wrapped in passive buffer gear cold
In 46 shaft, while the weighted spherical ball 52 of lowest part is risen by being classified gravity supporting plate 53, in the weighted spherical ball 52 of lowest part
It rises, the weighted spherical ball 52 of lowest part gradually holds up the weighted spherical ball 52 on top, to increase the pulling force of power steel wire 51, when people passes through
Afterwards, during door body 2 is closed, the closing force being subject to early period is maximum, and the later stage gradually decreases, and finally more slowly shuts door, simultaneously
When door is closed, pass through the sky for making slowly to be discharged in the insertion air of air constrictor axis 82 wedging ring 83 in air wedging ring 83
Gas plays the role of buffering and reduces vibrations, when needing to keep door body 2 normally opened, by rotating elastic adjusting bolt 65, makes passive tooth
Plate 62 and active tooth plate 63 compress power steel wire 51, to make door body 2 lose the power being automatically closed.
A kind of adjustable low precision automatic closing door of the invention, by using sealing platen 425, gasket 426 and sealing
Spring 427 coordinates, and can keep the buffering effect of reciprocal buffer part 42, while need not make buffering sleeve 421 and buffer shaft 422
There is higher cooperation precision, you can reach using compressed air as resisting medium, can finally door be made to be closed automatically, while can
Low to parts precision requirement by property height, processing cost is low, and long lifespan, maintenance cost is low, can be adjusted by power limiting section 6
The resistance that is closed automatically of door can more need to make door to maintain a normally open or normally closed, and adaptable, can better meet needs
It asks.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme all belong to the scope of protection of the present invention.
