Abstract
The invention discloses a movable dumbbell frame adjustable in height. The movable dumbbell frame comprises a base, wherein a pair of parallel directional pulleys and a pair of self-locking universalwheels are arranged at the bottom of the base; a lower supporting beam is fixedly arranged on one side of the top of the base, a height adjusting pipe is slidably arranged in a sliding groove in the lower supporting beam, and a plurality of through holes are formed in the side wall of the height adjusting pipe; a positioning hole is formed in the side wall of the lower supporting beam, and a positioning knob is inserted into the positioning hole; the positioning knob is in threaded connection with the positioning hole and penetrates through one through hole in the height adjusting pipe after being screwed into the positioning hole; an upper cross beam is fixedly arranged at the top of the height adjusting pipe, and dumbbell supports fixedly sleeve the two ends of the upper cross beam. Thedumbbell supports can be adjusted at multiple heights, so that trainees of different heights can conveniently use the dumbbell frame; when the self-locking universal wheels are locked, wheel shafts ofthe universal wheels and a steering shaft can be locked at the same time, so that locking is more stable, and the dumbbell falling risk is reduced; in the moving process, a brake handle can be used for braking in time, so that potential safety hazards are reduced.
