Abstract
A weight-adjustable dumbbell is mainly composed of a dumbbell rod assembly (1), multiple dumbbell pieces (7) and a dumbbell tray (9) used for containing the dumbbell pieces and the dumbbell rod assembly. The weight-adjustable dumbbell is characterized in that connectors (8-2) of a handle penetrate through handle installation through holes (2-7) in support control elements (2) to be fixedly connected to connecting grooves (6-4) in handle connecting columns on dumbbell piece gear-shifting control rotating discs (6) in an inserted mode through insertion grooves (8-1) in the connectors. The weight-adjustable dumbbell solves the problems that in the prior technical patent, because the weight of a weight-adjustable dumbbell is adjusted by rotating hand wheel rotating discs at the two ends in different directions, synchronous weight adjustment of the two sides can not be achieved, weight inconformity of the two ends of the dumbbell is likely to occur, and weight imbalance of the lifted dumbbell is caused. According to the weight-adjustable dumbbell, the pair of dumbbell piece gear-shifting control rotating discs (6) at the two ends of the handle can be conveniently driven to rotate just by rotating the handle (8) on the dumbbell rod assembly, and meanwhile multiple pairs of dumbbell locking and unlocking rotating discs (5) on a central spindle are driven to rotate, so that simultaneous and synchronous weight changing of the two sides of the lifted dumbbell is achieved, and synchronous weight adjustment of the two sides is achieved.
Description
Technical field
The invention belongs to a kind of athletic sports appliance, particularly relate to a kind of dumbbell with adjustable weight.
Background technology
Dumbbell is widely used as a kind of body-building apparatus, as chest spread training, the training of moon bright biceps and deltoid muscle training etc., is widely used.Dumbbell of the prior art mainly contains two kinds: a kind of dumbbell fixing for weight, and another kind is weight adjustable dumbbell; In use, the dumbbell that must prepare a set of Different Weight specification could meet the needs of trainer to the fixing dumbbell of the former weight, and to change weight can only be dismantle and change dumbbell plate frequently, uses and bothers very much; The latter is dark liking by training person because weight can regulate.The prior art patent No. is 200820075250.1 is exactly a kind of dumbbell with adjustable weight, although this dumbbell solves weight and fixes uncontrollable problem, but the weight of its adjustable dumbbell is the handwheel rotating disk by rotating two ends rotates the weight realizing adjustable dumbbell to both direction, the weight of adjustment both sides can not be synchronous, if rotate handwheel rotating disk not note scale slightly, be easy to cause the weight at dumbbell two ends inconsistent, cause the dumbbell weight of mentioning uneven, use cumbersome.Its inside arranges a safe lock dog locking device in addition, and when dumbbell bar leaves dumbbell pallet, safe lock dog makes trouble at complex structure.
Summary of the invention
The object of the invention is the shortcoming that exists for dumbbell with adjustable weight in prior art and design and provide a kind of and need not dismantle dumbbell plate, when dumbbell assembly is placed on dumbbell pallet, only, needs the handle rotated on dumbbell bar assembly just can change a kind of dumbbell with adjustable weight of weight when dumbbell is mentioned easily, and regulate the weight of both sides synchronously to carry out, operation is very easy in use, structure is simple, easy to manufacture.
