[0033] Working principle:

[0034] When actually using the electric curtain retraction buffer device, the sleeve frame plate 2 can be sleeved onto the side wall of the curtain rod 1, and then the sleeve frame plate 2 can be moved laterally along the curtain rod 1. During this process, the serrated plate 14 can drive the gear 12 to rotate. At the same time, the grooved wheel 11 abuts against the curtain rod 1 to prevent the sleeve frame plate 2 from shifting. When the curtain rod 1 moves to the appropriate position, the four sets of threaded through holes and the four sets of fastening bolts 16 are engaged with each other. The operator can manually rotate the four sets of fastening bolts 16 clockwise. When the brake pads 17 contact the four sets of frosted rings 15, friction ensures the stability of the connecting frame plate 2. When the hanging ring moves laterally, it impacts the two sets of ball rods 7 on the same side. The two sets of ball rods 7, with the help of two sets of dampers 6 and two sets of shock-absorbing springs on the same side, buffer the impact of the hanging ring, achieving the purpose of cushioning the hanging ring during the raising and lowering of the curtains. The connecting frame plate 2 allows for adjustment of the buffer structure's position according to usage requirements, improving the practicality of the electric curtain raising and lowering buffer device. Simultaneously...

The operator can rotate the four sets of connecting screws 4 counterclockwise by hand to remove the four sets of protective covers 5, and then inspect the four sets of dampers 6 and the four sets of shock-absorbing springs. After the inspection is completed, the two sets of sealing plugs 21 can be pulled out, and then the output end of the external air pump can be connected to a set of mounting pipes 22. When the external air pump is powered on, air can enter the interior of a set of air storage chambers 18 through the mounting pipes 22, and then the air can enter the interior of the two sets of threaded blind holes 3 on the same side through multiple sets of connecting pipes 19 on the same side. The flowing air can blow out the blockages inside the two sets of threaded blind holes 3. The other set of mounting pipes 22 can be used in the same way. Afterwards, the four sets of connecting screws 4 can be rotated clockwise and inserted back into the interior of the four sets of threaded blind holes 3, waiting for the next use of the buffer.
