The application relates to the technical field of treadmills, in particular to a
treadmill with a pneumatic lifting structure, which comprises a
treadmill main body, a
handrail part and a lifting part; the
treadmill main body comprises a rack, and a running track is arranged on the rack; the lifting part comprises: a lifting frame, which is rotatably arranged on the rack; a
pneumatic cylinder, which comprises a fixed end and an extension end, the fixed end is rotationally connected with the rack, and the extension end is rotationally connected with the lifting frame; and a locking part, which is arranged on the
pneumatic cylinder and is used for locking the extension end of the
pneumatic cylinder. The application has the advantages that: the application adopts the pneumatic cylinder as a lifting power source, compared with the traditional electric push rod, has the advantages of simple structure, low cost and low operation
noise, meanwhile, through the arrangement of the locking part, the extension end of the pneumatic cylinder is mechanically locked after being lifted to the position, the problem that the running track shakes and cannot be long-term pressure-kept due to the
compressibility of the gas in the pure pneumatic structure is overcome, and the perfect combination of low-
noise adjustment and high-strength locking is realized.
