Abstract
Variable mass dumbbell based on constant volume belongs to physical fitness equipment; This dumbbell comprises handle (1) and dumbbell plate (2), it is characterized in that, described handle (1) and dumbbell plate (2) make integrative-structure by Digital printing technology, the upper cover of described dumbbell plate (2) has sponges cover (3), the distribution of dumbbell plate (2) Side symmetrical is porose, be provided with weight adjustment block (4) in hole, described weight adjustment block (4) inside is provided with the hollow-core construction of different volumes; The utility model dumbbell, can be implemented in when not changing dumbbell volume, the weight of adjustment dumbbell.
Description
Technical field
Variable mass dumbbell based on constant volume belongs to physical fitness equipment.
Background technology
Dumbbell is a kind of simple equipment for strengthening muscle strength training.Traditional dumbbell employing dumbbell plate is screwed in the structure on handle, by screwing the dumbbell plate of different quality varying number, realizes the adjustment to dumbbell weight.
Under this configuration, the quality of adjustment dumbbell will certainly change the volume of dumbbell, and trainer, while adjustment dumbbell weight, due to the change of dumbbell volume, also needs to adjust the posture of taking exercise.
Utility model content
In order to solve the problem, the utility model devises a kind of variable mass dumbbell based on constant volume, can be implemented in when not changing dumbbell volume, the weight of adjustment dumbbell.
The purpose of this utility model is achieved in that
Based on the variable mass dumbbell of constant volume, comprise handle and dumbbell plate, described handle and dumbbell plate make integrative-structure by Digital printing technology, on described dumbbell plate, cover has sponges cover, the distribution of dumbbell plate Side symmetrical is porose, be provided with weight adjustment block in hole, described weight adjustment block inside is provided with the hollow-core construction of different volumes.
The above-mentioned variable mass dumbbell based on constant volume, it is following several one that the installation between described hole and weight adjustment block is closed:
Relation one, hole are tapped through hole or tapped blind hole, and weight adjustment block outer setting has screw thread, and weight adjustment block screws in hand-hole;
Relation two, hole are blind hole, and the bottom in hole is connected by joint with weight adjustment block;
The sidewall of relation three, hole and weight adjustment block is provided with permanent magnet, utilizes opposite pole to attract mutually to realize the constraint of hole to weight adjustment block.
Beneficial effect:
The first, owing to being provided with the hollow-core construction of different volumes by weight adjustment block inside, therefore only needing the volume by adjusting hollow parts, under just can be implemented in the condition not changing weight adjustment block volume, changing the weight of weight adjustment block; By installing or not erection weight adjustment block in the hole of dumbbell plate, or the weight adjustment block of different quality being installed, realizing while not changing dumbbell volume, change the quality of dumbbell.
The second, due to the constancy of volume of dumbbell, therefore can overlap on dumbbell plate and have sponges cover, realize the function of protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model based on the variable mass dumbbell of constant volume.
In figure: 1 handle, 2 dumbbell plates, 3 sponges covers, 4 weight adjustment blocks.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is described in further detail.
Specific embodiment one
The variable mass dumbbell based on constant volume of the present embodiment, structural representation as shown in Figure 1.This dumbbell comprises handle 1 and dumbbell plate 2, described handle 1 and dumbbell plate 2 make integrative-structure by Digital printing technology, on described dumbbell plate 2, cover has sponges cover 3, the distribution of dumbbell plate 2 Side symmetrical is porose, be provided with weight adjustment block 4 in hole, described weight adjustment block 4 inside is provided with the hollow-core construction of different volumes.
Installation between described hole and weight adjustment block 4 is closed: hole is tapped through hole or tapped blind hole, and weight adjustment block 4 outer setting has screw thread, and weight adjustment block 4 screws in hand-hole.
Specific embodiment two
The variable mass dumbbell based on constant volume of the present embodiment, is from the different of specific embodiment one, and the installation between described hole and weight adjustment block 4 is closed and is: hole is blind hole, and the bottom in hole is connected by joint with weight adjustment block 4.
Described joint can adopt the concrete structures such as socket latch, and those skilled in the art can designed, designed or directly adopt prior art, no longer repeat specification in this application as required.
Specific embodiment three
The variable mass dumbbell based on constant volume of the present embodiment, be from the different of specific embodiment one, installation between described hole and weight adjustment block 4 is closed: the sidewall of hole and weight adjustment block 4 is provided with permanent magnet, utilizes opposite pole to attract mutually to realize the constraint of hole to weight adjustment block 4.
