Abstract
An adjustable dumbbell comprises a plurality of weight plates, wherein any weight plate is provided with an axial pore channel and a radial track which is partially staggered with the axial pore channel. Two ends of a rod body are respectively accommodated in the axial pore channels of the weight plates, and two ends of the rod body are respectively provided with a plurality of scarf grooves. The positioning piece is movably accommodated in a radial track of a weight plate, when a long groove arranged on the positioning piece is limited by a stopping part, the positioning piece can move in the radial track, and the positioning piece can be positioned at a preset position through the positioning action of a first positioning part and a second positioning part arranged on the positioning piece, so that the weight plate and the rod body are in a clamping state, and a user can train arm strength or separate the weight plate from the rod body to adjust the weight of the dumbbell.
Description
Technical field
The utility model relates to a kind of dumbbell, be particularly related to a kind of mobile or fixing in the radial track of counterweight plate by positioning piece, make the counterweight plate and the body of rod be clip or pine oil state, to increase or to reduce the quantity of counterweight plate, thereby adjust the weight of dumbbell, be available for users to carry out the adjustable dumbbell of SAE.
Background technology
Have the structure of adjusting the counterweight plate mostly at the dumbbell of in the streets using at present, but, in material cost, assembling and use operation, sizable difference is arranged promptly because each adjusts the difference of structure as SAE.
See also shown in Figure 9, it is arm-strength exercising device for a kind of existing plate of loading, unloading counterweight fast, comprise that mainly a fixed bar a and array be located at the counterweight plate b on the fixed bar a, each counterweight plate b is respectively equipped with one and extends to inner long slot bore b1 from outer ring surface, become with described long slot bore b1 to be provided with one among the counterweight plate b of alternate directions and be subjected to the driving of elastic parts c and the latch d of expandable, the front end of described latch d can pass from long slot bore b1 and be resisted against the upper surface of fixed bar a, makes latch d and fixed bar a be the clip state.
But by said structure ease of assembly or dismounting counterweight plate b really, the convenience when using to increase.Yet it still has following disappearance to wait to improve:
1, described latch d is when being installed on counterweight plate b inside, and the restriction that must be fixed in the catch e of counterweight plate b outer peripheral edges by an elastic parts c and can make latch d location, to link fixed bar a and counterweight plate b.And for reaching this purpose, form suitable many of member, will increase production cost relatively.
2, when the end of latch d and fixed bar a are the clip state, for allowing the user can conveniently spur the other end of latch d, so that latch d separates with fixed bar a, the other end of described latch d will quite protrude from the outer peripheral edges of counterweight plate b, on the plectane profile of whole counterweight plate b, seem quite lofty, influence user's impression.And when reality was used, user's danger because of counterweight plate b is separated with fixed bar a, was caused easily in the protruding end of described latch d.
In view of this, in order to improve above-mentioned shortcoming, make adjustable dumbbell can not only reduce member to save cost, and can make each member be merged into monnolithic case in, safe in utilization to guarantee, long-pending experience and the constantly research and development improvement for many years of inventor has generation of the present utility model then.
Summary of the invention
Main purpose of the present utility model is providing a kind of adjustable dumbbell, by ccontaining one removable or be fixed in the keeper in precalculated position in the radial track of counterweight plate, make the counterweight plate and the body of rod be clip or pine oil state, can simplify member, to save material and assembly cost.
Secondary objective of the present utility model is providing a kind of adjustable dumbbell, by positioning piece being placed in the radial track of counterweight plate, make keeper can be placed in the radial track of counterweight plate fully, can make the monnolithic case of counterweight plate complete, and can avoid keeper by malfunction, and can guarantee user's safety.
For reaching the purpose of above-mentioned utility model, the utility model provides a kind of adjustable dumbbell, it is characterized in that, comprise: a plurality of counterweight plates, described counterweight plate be respectively equipped with an axial channel and one and described axial channel be the staggered radial track of part, a stop section and one first location division are located at respectively in the described radial track; One body of rod, its two end is placed in respectively in the axial channel of each counterweight plate, and two ends of the described body of rod are respectively equipped with a plurality of scarfing slots; A plurality of keepers are movably to be placed in respectively in the radial track of each counterweight plate, and described keeper is respectively equipped with a long slot bore, and described again keeper is provided with second location division of a cooperation first location division.
The axial channel of described counterweight plate is for extending inwardly to inner elongate slot from outer peripheral edges.Two ends of the described body of rod comprise a plurality of tool spaced-apart ring-shaped depressed parts respectively, and the top of described annular recess is respectively equipped with scarfing slot.Two sides of the annular recess of the described body of rod are excised respectively, form two relative cutting planes, and described annular recess is passed through the middle position of the elongate slot of counterweight plate to the counterweight plate.Described stop section is to be convex shape, and an end of its path and counterweight harden and close, and passes the long slot bore of keeper, and an end in big footpath protrudes from the long slot bore outside, and the size of an end in described big footpath is bigger than the groove width size of long slot bore.Described first location division comprises at least one snap-on, and described second location division comprises at least one locating hole.Described keeper is L-shaped.
By this, when the outer peripheral edges of keeper by the counterweight plate inwardly move radially, when making an end of keeper be sticked in the scarfing slot of the body of rod, the described counterweight plate and the body of rod are the clip state, are available for users to carry out SAE; And when keeper was moved by the middle body outward radial of counterweight plate, the described body of rod broke away from the control of keeper, and the counterweight plate is separated with the body of rod, to adjust the weight of dumbbell.
The utlity model has following advantage:
1, the utility model to reach firm function in conjunction with counterweight plate and the body of rod and adjustment dumbbell weight, can effectively be saved material and assembly cost by simple member.
2, the utility model by positioning piece being placed in fully in the radial track and short slot of counterweight plate, can effectively be avoided separating with the body of rod because of the malfunction keeper makes the counterweight plate, to guarantee user's safety when the counterweight plate combines with the body of rod.
For ease of more deep understanding being arranged, after being specified in to the utility model.
