When the door and window is pressed down once, because the two sliding blocks 21 are always contacted by the first spring, the upper ends of the two supporting plates 22 are closed towards the middle to form extrusion force on the air cylinder assembly 3, and at the moment, when the two supporting plates 22 push the piston rod 35 to move respectively towards the left cylinder body 31 and the right cylinder body 32, the air in the left cylinder body 31 is compressed due to the existence of the connecting piece 33.
After the piston rod 35 in the left cylinder 31 moves to the right and the gas in the left cylinder 31 is compressed, with the pressure to the door and window disappearing, the piston rod 35 of the left cylinder 31 is pushed out under the dual function of the elastic force of the second spring and the gas pressure, the support plate 22 is pushed to rotate along the opposite direction, the two support plates 22 keep rotating synchronously due to the existence of the gear disc 221, the piston rod 35 of the right cylinder 32 also moves outwards, in the process, the inside of the right cylinder 32 is in a negative pressure state, the compressed air in the left cylinder 31 enters the right cylinder 32 through the vent hole of the base 331, due to the existence of the silicone rubber pad 333, the gas entering the right cylinder 32 can not return to the left cylinder 31 through the vent hole, and at the same time, the piston 34 in the left cylinder 31 will move to the initial position in the left cylinder 31 to form negative pressure due to the action of the second spring, and the outside air enters the left cylinder 31 through the air inlet hole to realize air inflation. After the completion is once pressed, the volume of the gas in the left cylinder body 31 is basically unchanged, the gas in the right cylinder body 32 is increased, the distance between the two supporting plates 22 is increased by the cylinder assembly 3, the outer frame 1 is lifted for a certain distance, and after the door and window is repeatedly pressed for many times, the height can be adjusted.
When the left cylinder body 31 is in a negative pressure environment, gas enters the oil storage tank through the rubber ring 334, gas cleaning and impurity filtering are achieved in the oil storage tank, the filtered gas enters the left cylinder body 31 through the air inlet hole, and inflation of the left cylinder body 31 is achieved.
When the height of the door window needs to be reduced, the push rods of the pulley assemblies 2 are pressed, gas in the gas storage cavity of the right cylinder body 32 of one pulley assembly 2 is discharged from the gas outlet through the gas pipe and the connecting port through the pressure release valve 4 on the other pulley assembly 2 to realize pressure release, and the push rods of the two pulley assemblies 2 are pressed simultaneously to realize simultaneous pressure release of the two pulley assemblies 2, so that the two pulley assemblies 2 are ensured to be positioned at the same horizontal position all the time, and the service life of the pulley 23 is prolonged.
While the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
