The invention discloses an air-resistance type
strength training device, which relates to the technical field of
sports equipment, and adopts the technical scheme that the air-resistance type
strength training device comprises a device base, the upper part of the device base is fixedly connected with a resistance cavity, the upper part of the resistance cavity is fixedly connected with a connecting
pipe, the upper part of the connecting
pipe is fixedly connected with a locking shell, and the locking shell is fixedly connected with the resistance cavity; a
piston is slidably connected into the locking shell, the upper portion of the
piston and the locking shell are combined to form a resistance
air cavity, and the lower portion of the
piston and the locking shell are combined to form a locking
air cavity. The air pressure in the locking
air cavity communicated with the upper portion of the resistance cavity through the connecting
pipe can be synchronously increased, the piston can be driven to move upwards when the air pressure in the locking air cavity is increased, and therefore the locking
steel ball is compressed to move inwards to lock the lifting
rope, and excessive
force generation in the training process of personnel is avoided.
