Movable dumbbell frame adjustable in height

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.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a height-adjustable mobile dumbbell rack. Background technique [0002] At present, dumbbell racks are mostly fixed due to their large load-bearing capacity. A small number of light dumbbell racks for families use movable pulleys. However, the height of these light dumbbell racks cannot be adjusted, and trainers of different heights cannot adjust according to the actual situation when using them. It makes it inconvenient to pick and place the dumbbells; when the universal wheels of the existing dumbbell rack are locked, the wheels cannot be rotated, but the steering shaft of the universal wheels can still rotate, and the locking is unstable. There is a risk of the dumbbells falling when placing the dumbbells, which increases safety. Hidden danger: the existing dumbbell stand is difficult to brake in time due to the weight and inertia of the dumbbells in the moving proce...

Problems solved by technology

[0002] At present, dumbbell racks are mostly fixed due to their large load-bearing capacity. A small number of light dumbbell racks for families use movable pulleys. However, the height of these light dumbbell racks cannot be adjusted, and trainers of different heights cannot adjust according to the actual situation when using them. It makes it inconvenient to pick and place the dumbbells; when the universal wheels of the existing dumbbell rack are locked, the wheels cannot be rotated, but the steering shaft of the universal wheels can still rotate, and the locking is unstable. There is a risk of the dumbbells falling when placing the dumbbells, which increases safety. Hidden danger: Due to the weight and inertia of the dumbbells in the moving process of the existing dumbbell rack, it is difficult to brake in time by relying on the strength of the arm, which also increases the safety hazard
