Background technology
Dumbbell is a kind of conventional sports equipment of physical education.Less than barbell, and not free during motion.
In order to save the cost making dumbbell, dumbbell head can be made cavity structure by existing dumbbell, is injected by water in use.This dumbbell cost is lower, and weight convenient sources.But said structure cannot ensure that the water weight that the dumbbell head of both sides injects is identical, thus causing deflection to occur when taking exercise, being unfavorable for taking exercise; , because water is liquid, can rock in use meanwhile, when people can cause varying in weight of two ends when using dumbbell exercise because of rocking of water, be unfavorable for equally taking exercise, and wrist can be caused to pull because the weight difference at two ends is excessive.
Summary of the invention
For the problems referred to above, the utility model provides a kind of physical education self-balancing dumbbell, and structure is simple, by the weight of water in the dumbbell head of leveling two ends, guarantees student's balance in use, avoids the wrist caused because two ends are unbalanced to pull.
For achieving the above object, a kind of physical education self-balancing dumbbell of the utility model, comprise the dumbbell head at dumbbell bar and two ends, dumbbell head inside is cavity structure, and the mid portion of cavity structure is cylindric, and the inclined-plane, upper end of dumbbell head has water injection hole;
Meanwhile, dumbbell head is also provided with compressed water generation apparatus, water level observation pipe, liquid level gauge and display screen; Wherein, dumbbell head upper end is provided with screwed pipe; Compressed water generation apparatus is made up of compressor arm and water squeezing plate, and compressor arm upper end has screw thread, and the screwed pipe arranged with dumbbell head upper end coordinates, water squeezing plate is installed in compressor arm lower end, water squeezing plate is discoideus, is arranged in the cavity structure of dumbbell head, diameter 2-3mm less of the mid portion diameter of dumbbell head; Water level observation pipe is arranged on the outer surface of dumbbell head, is connected by flexible pipe with the inside of dumbbell head; Liquid level gauge) be arranged in water level observation pipe, be connected with the display screen electric wire being arranged on outside.Dumbbell bar is the telescopic structures in two ends, and the distance of maximal dilation is 15cm-20cm, and at its two ends and centre position, telescopic intersection is carved with size scale, is filled with colored paint in scale.
Further, water squeezing plate is rubber circular plate.
Further, liquid level gauge arranges more than one, is arranged in water level observation pipe.
Further, connection electric wire arranged outside one deck watertight composition of liquid level gauge and display screen.
Further, liquid level counts magnetic float liquidlevel meter.
Further, the cavity structure inwall of dumbbell head is provided with one deck antirust coat.
Compared with the dumbbell of existing dress water, the utility model is water level observation pipe in dumbbell arranged outside, and be provided with liquid level gauge and display screen respectively in the inside of water level observation pipe and outside, wherein, water level in observation tube is converted into signal transmission to display screen and conversion data display by liquid level gauge, thus guarantees that the weight of water filling in the dumbbell head of two ends is identical; Meanwhile, rotate compressed water generation apparatus, compressor arm drives the water squeezing plate extruding water surface, prevent water surface activities, leave space simultaneously, prevent the ejection of water in extrusion process, thus further ensure that the balance of two ends water weight, avoid the wrist caused because two ends are unbalanced and pull.On this basis, dumbbell bar is the telescopic structures in two ends, and the distance of maximal dilation is 15cm-20cm, and at its two ends and centre position, telescopic intersection is carved with size scale, is filled with colored paint, guarantees leveling in scale, and then ensures the safety of student.

Fig. 2 is the schematic enlarged-scale view at A place in Fig. 1.
In figure: 1, dumbbell bar, 2, dumbbell head, 3, compressor arm, 4, water injection hole, 5, water level observation pipe, 6, water squeezing plate, 7, liquid level gauge, 8, display screen.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of physical education self-balancing dumbbell, comprises the dumbbell head 2 at dumbbell bar 1 and two ends, and dumbbell head 2 inside is cavity structure, and the mid portion of cavity structure is cylindric, and the inclined-plane, upper end of dumbbell head 2 has water injection hole 4
It is characterized in that, dumbbell head 2 is also provided with compressed water generation apparatus, water level observation pipe 5, liquid level gauge 7 and display screen 8;
Wherein, dumbbell head 2 upper end is provided with screwed pipe; Compressed water generation apparatus is made up of compressor arm 3 and water squeezing plate 6, wherein, compressor arm 3 upper end has screw thread, the screwed pipe arranged with dumbbell head 2 upper end coordinates, water squeezing plate 6 is installed in compressor arm 3 lower end, water squeezing plate 6 is discoideus, is arranged in the cavity structure of dumbbell head 2, diameter 2-3mm less of the mid portion diameter of dumbbell head 2;
Water level observation pipe 5 is arranged on the outer surface of dumbbell head 2, is connected by flexible pipe with the inside of dumbbell head 2; Liquid level gauge 7 is arranged in water level observation pipe 5, is connected with display screen 8 electric wire being arranged on outside.
