A kind of body-building apparatus
Technical field
The present invention relates to a kind of body-building apparatus, relate in particular to a kind of family expenses body-building apparatus.
Background technology
In numerous body-building apparatus, small and exquisite gravity body-building apparatus simple in structure is applicable to that the most family uses.The basic structure of this body-building apparatus is generally two gravity body and is connected as a single entity by a handle.Adopt the defective of the fitness equipment of this structure to be, the gravity of body-building apparatus mainly is distributed in the axis of handle or near axis, make that its scope of application is single, be difficult to satisfy the popular demand of using single body-building apparatus to use a plurality of positions of different exercise methods exercise whole bodies.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of fitness equipment, and its weight distribution is disperseed, and using method is various.
For solving the problems of the technologies described above, the invention provides a kind of body-building apparatus with following structure:
A kind of body-building apparatus, comprise gravity body and the handle that is connected with this gravity body, it is characterized in that: described gravity body is a circulus, and handle is positioned at radially position of described circulus, installation and positioning structure is established in handle and gravity body junction, and handle end and gravity body are for detachably being fastenedly connected.
Preferably, described installation and positioning structure is specially: offer the handle mounting groove of square on the gravity body inner ring surface relatively, the both ends of described handle cut out the handle key face suitable with aforementioned handle mounting groove respectively.
Preferably, have the fastening screw that is used for handle is fixed in gravity body in the described handle mounting groove, handle is packed into behind the handle mounting groove, tightens handle and gravity body fixing by fastening bolt.
Preferably, described gravity body is a circular ring.
Preferably, described grip surface is provided with anti-skid structure.
Preferably, the anti-skid structure of described handle is the ridge design that is provided with in grip surface.
Preferably, the surface coverage matcoveredn of described gravity body
Preferably, described gravity body is wrapped up the protective jacket that elastic caoutchouc is made.
Compared with prior art, body-building apparatus of the present invention is owing to adopt the ring-type gravity body, the weight distribution of body-building apparatus has become ring-type by wire, thereby make this body-building apparatus of utilization can carry out the more body-building content of horn of plenty, not only can make more body part obtain taking exercise, and increase the enjoyment of body-building.
Description of drawings
Fig. 1 is the stereochemical structure decomposing schematic representation of body-building apparatus embodiment of the present invention.
Employed mark is respectively in the above accompanying drawing:
The 1-gravity body, 11-handle mounting groove, the fastening screw of 12-gravity body, 2-handle, 21-handle key face, the fastening screw of 22-handle, 3-fastening bolt, 31-pad, 4-protective jacket, 41-protective jacket seam
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of the specific embodiment.
As shown in drawings, this body-building apparatus has one and is the handle 2 that circular gravity body 1 and surface are provided with decorative pattern.2 handle mounting grooves 11 that offer square respectively with center of circle symmetry on the inner ring surface of described gravity body 1 have the fastening screw 12 of gravity body of penetrating described gravity body in the handle mounting groove 11.The both ends of described handle 2 cut out the handle key face 21 suitable with aforementioned handle mounting groove 11 respectively, and from handle 2 end faces inwardly direction offer the fastening screw 22 of handle.With pack into handle mounting groove 11 on the gravity body 1 of handle 2, use fastening bolt 3 to install pad 31 additional and both are tightened fixing.At this moment, handle 2 is subjected to the fixing of fastening bolt 3 at its axis direction, is subjected to the fixing of handle mounting groove 11 at circumferencial direction.Further, the appearance of this gravity body 1 has sprayed flexible material as protective layer, and the outside of gravity body also is enclosed with the protective jacket of being made by elastomeric material 4, and when body-building apparatus fell accidentally, flexible protective jacket 4 can play buffer protection function effectively.
The handle of fitness equipment of the present invention also can be to have only one of them end detachably to fixedly connected with gravity body.
Use the enhancing body resistance equipment can carry out multiple body-building to temper different body parts, for example: both hands are held ring-type gravity body 1 respectively simultaneously, the palm of the hand is inside, the ring-type gravity body placed to keep flat before the body press down the dedicate one's life to body limit, and promote repeatedly, not only can temper arm, shoulder muscle, ligament can stretch simultaneously; For another example: both hands are held gravity body 1 respectively simultaneously, keep flat before the ring-type gravity body is placed body, and both arms Cross Trade repeatedly change, and can make the ligament of arm, shoulder obtain stretching; Again for example: both hands are held ring-type gravity body 1 respectively simultaneously, with gravity body be affixed on the back neck, use suitable power with annular solid draw outward, preceding pressure, not only can temper arm, shoulder and also can carry out pliable and tough training neck, vertebra.
Compared with prior art, body-building apparatus of the present invention is owing to adopt the ring-type gravity body, the weight distribution of body-building apparatus has become ring-type by wire, thereby make and use this body-building apparatus can carry out the more body-building content of horn of plenty, not only can make more body part obtain taking exercise, and increase the enjoyment of exercise activity.
More than disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
