Abstract

The utility model relates to a free rotating dumbbell, in particular to a dumbbell used in exercise and provided with eccentric inertia wheels which can rotate freely at two ends, and belongs to the field of fitness equipment. The dumbbell comprises a grip (1) and balancing weights at two ends of the grip (1). The free rotating dumbbell is characterized in that each balancing weight is designed into a hollow weight box, the weight boxes are fixed at two ends of the grip (1) through an internal fixing shaft (3), an eccentric inertia wheel (5) capable of rotating eccentrically is installed in each weight box, and the eccentric inertia wheels (5) are installed at the outer ring of the fixing shaft (3) through bearings (4). According to the free rotating dumbbell, the eccentric inertia wheels in the balancing weights at two ends of the grip can rotate freely according to the motion mode of an arm, and therefore sports fun and an exercise effect are increased.

Description

Rotate freely dumbbell

Technical field

Rotate freely dumbbell, belong to the body-building apparatus field, be specifically related to a kind of two ends and be furnished with the body-building dumbbell that can rotate freely eccentric flying wheel device.

Background technology

Traditional dumbbell is generally that two balancing weights or the adjustable balancing weight of polylith are fixed respectively in the two ends of a handle.The person taking exercise uses dumbbell do the arm strength training or jump dumbbell exercises, and common dumbbell in use motion mode is more dull, lacks the rhythm and timing.

Summary of the invention

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide the eccentric flying wheel of the balancing weight inside at a kind of dumbbell handle two ends to rotate freely according to the arm motion mode, increased sports fun and exercise effect rotate freely dumbbell.

The technical scheme that its technical problem that solves the utility model adopts is: this rotates freely dumbbell, the balancing weight that comprises handle and handle two ends, it is characterized in that: described balancing weight is designed to the ballast box of boring, two ballast boxes fixed axis by inside is fixed on handle two ends, installation can be done the eccentric flying wheel of eccentric rotary in ballast box, and two eccentric flying wheels all are arranged on the fixed axis outer ring by bearing.When the handle that holds dumbbell as the user circulated rhythmically and takes exercises, the eccentric flying wheel at dumbbell two ends was followed the movement locus of arm and is done eccentric rotary.

Described ballast box is comprised of casing and the end cap of an end opening, box opening outwardly, end cap seal is at the opening part of casing.

Described casing is that the cross section is circular cylinder, and end cap is the circular lid of covering at the cylinder opening place.

Described casing is that the cross section is foursquare square tube, and end cap is the square lid that covers at the square tube opening part.

Described casing is that the cross section is polygonal many prismatics bucket, and end cap is the many prismatic lids that cover at many prismatics bucket opening part.

Totally two of described fixed axis are fixed on respectively handle two ends with one heart.

Compared with prior art, the beneficial effect that has of the utility model is:

1, changed the using method of traditional dumbbell, enriched the train on of dumbbell, when the handle that holds dumbbell as the user circulates rhythmically and takes exercises, the eccentric flying wheel at dumbbell two ends is followed the movement locus of arm and is done eccentric rotary, effect due to eccentric flying wheel eccentric rotary, arm can be experienced rhythmical strength and change in motion process, make motion that the rhythm and timing more be arranged, and this motion mode has increased enjoyment and the train on of motion;

2, simple in structure, easy to make, cost is low, is suitable for extensive popularization.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model structure explosive view.

Wherein: 1, handle 2, casing 3, fixed axis 4, bearing 5, eccentric flying wheel 6, end cap.

The specific embodiment

Fig. 1 ~ 2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.

Embodiment 1

With reference to accompanying drawing 1 ~ 2: this rotates freely dumbbell, comprises the balancing weight at handle 1 and handle 1 two ends, and balancing weight is designed to the ballast box of boring, and two ballast boxes fixed axis 3 by inside is fixed on handle 1 two ends.Totally two of fixed axis 3 are fixed on respectively handle 1 two ends with one heart, the outer suit bearing 4 of fixed axis 3, and the eccentric flying wheel 5 that can do eccentric rotary is installed in bearing 4 outer rings.

Ballast box is comprised of casing 2 and the end cap 6 of an end opening, and casing 2 is fixed on handle 1 two ends by fixed axis 3, opening outwardly, end cap 6 is sealed in the opening part of casing 2, casing 2 is circular cylinder for the cross section, end cap 6 is for covering the circular lid at the cylinder opening place.

Embodiment 2

Casing 2 is foursquare square tube for the cross section, and end cap 6 is for covering the square lid at the square tube opening part, and all the other settings are identical with embodiment 1.

Embodiment 3

Casing 2 is polygonal many prismatics bucket for the cross section, and end cap 6 is for covering the many prismatic lids at many prismatics bucket opening part, and all the other settings are identical with embodiment 1.

Operation principle is as follows: when the handle 1 that holds dumbbell as the user circulates rhythmically and takes exercises, the eccentric flying wheel 5 at dumbbell two ends is followed the movement locus of arm and is done eccentric rotary, effect due to eccentric flying wheel 5 eccentric rotaries, arm can be experienced rhythmical strength and change in motion process, make motion that the rhythm and timing more be arranged, this motion mode has increased the enjoyment of motion and the effect of exercise.

The above, it is only preferred embodiment of the present utility model, be not to be the utility model to be done the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
