Detailed Description

As shown in fig. 1-5, a spring 22 is arranged in the shaft sleeve 21, an adjustable bearing 23 is arranged in the spring 22, a one-way bearing 24 is arranged outside the adjustable bearing 23, a driving shaft 25 is arranged in the adjustable bearing 23, and a screw air-blowing device 26 is arranged below the driving shaft 25.

In this embodiment, the outer side of the shaft sleeve 21 is connected with a door frame installation page 27, one end of the clockwork spring 22 is fixedly connected with the inner wall of the shaft sleeve 21, and the other end of the clockwork spring 22 is fixedly connected with the outer wall of the adjustable bearing 23.

In this embodiment, the one-way bearing 24 is sleeved at the upper end and the lower end of the adjustable bearing 23, the outer wall of the one-way bearing 24 is connected to the door mounting leaf 28, and the door frame mounting leaf 27 and the door mounting leaf 28 are both provided with fixing holes 29.

In this embodiment, the upper portion of the driving shaft 25 is fixedly installed in the inner wall of the adjustable bearing 23, and the lower portion of the driving shaft 25 is connected to the screw 30 of the screw blowing device 26.

In this embodiment, a screw sleeve 31 is arranged outside the screw 30, a bearing hole 32 is arranged at the upper end of the screw sleeve 31, a ball bearing 33 is arranged in the bearing hole 32, and the driving shaft 25 is arranged at the upper end of the screw sleeve 31 through the ball bearing 33.

In this embodiment, a plurality of air inlets 34 are opened at the upper end of the screw sleeve 31, an air outlet 35 is opened at the lower end of the screw sleeve 31, the air outlet 35 is located under the screw 30, and a quick connector 36 is further arranged on the air outlet 35.

As shown in the figure, the adjustable bearing 23 rotates the adjusting ring 4 anticlockwise to enable the ratchet hook 12 to extend out of the limiting hole 16, at the moment, the ratchet hook 12 and the ratchet 19 can be mutually hooked together, when the outer bearing seat 3 rotates clockwise, the ratchet hook 12 is limited by the limiting hole 16, the tip end is clamped with the ratchet 19, and the outer bearing seat 3 cannot rotate clockwise. However, when the ratchet 19 rotates counterclockwise, the ratchet 12 is only pushed into the ratchet housing 15, and the rotation is not affected. The bearing becomes a one-way bearing.

When the door mounting leaf 28 rotates anticlockwise, the one-way bearing 24 can not rotate relatively, so that power is directly transmitted to the outer bearing seat 3 of the adjustable bearing 23, and the outer bearing seat 3 drives the spring 22 to contract to store energy. With the adjustable bearing 23 as described above, the outer bearing housing 3 rotating counterclockwise will not drive the inner bearing housing 1 to rotate. When the door leaf 28 is released, the potential energy released by the spring 22 will return the door leaf 28 to its original position, but now the clockwise rotation of the outer housing 3 will drive the inner housing 1 to rotate clockwise, and the drive shaft 25 connected to the inner housing 1 will also start to rotate. The drive shaft 25 drives the entire blower to generate an air flow.

The air flow flows into the air tube 54 in the door panel, is released into the air accumulation chamber 52 along with the air tube 54, is pressurized by the air curtain outlet 50, is discharged from the door gap, and blocks the smoke from entering.

The adjusting ring 4 can also be rotated clockwise to put the ratchet 12 into the ratchet shell 15, at this time, the adjustable bearing 23 becomes a bidirectional bearing, the driving shaft 25 can not receive any power, but the hinge can be opened and then returns to the original position.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
