The cabinet machine on the market at present takes the electric lift as the leading factor, and the structure is complicated, and the cost is higher. The utility model provides a lift cabinet machine realizes going up and down and locking through hanging pneumatic elevating system to reduce manufacturing cost, bring convenience in life for more families. The lifting control method of the lifting cabinet machine is the same as that of the lifting clothes hanger of embodiment 2, in addition, the slide rails 93 are installed on both sides of the article rack 92 to realize the lifting guiding function of the article rack 92, and the guard rails 922 are installed on the supporting plate 921 to place different kitchen utensils and seasonings.

The utility model provides a pneumatic elevating system of multipurpose suspension type simple structure, overall arrangement are compact. The extension and contraction of the piston rod of the lockable gas spring 2 are utilized to drive the idler wheel on the piston rod to displace, and the mechanism lifting function is realized through the movement of left and right steel wire ropes (31 and 32) wound on the idler wheel. Because the left and right steel wire ropes (31, 32) are folded when bypassing the first and second rollers (51, 52), when the piston rod of the lockable gas spring 2 extends or contracts for a certain length, the moving distance of the left and right steel wire ropes (31, 32) in the vertical direction is 2 times of the extending or contracting length of the piston rod, and the lifting stroke is amplified. The suspension type pneumatic lifting mechanism can be applied to various lifting products, and is wide in application range.

The foregoing is only a partial description of the present invention, and it should be understood that various other modifications, improvements and equivalents may be made without departing from the spirit and scope of the invention as defined by the appended claims.
