Abstract
An arm-strength device can adjust the force degree. One ends of the two metal rods 11, 12 of the arm-strength device are respectively articulated with the same side of the middle part of a metal rod 30 and are connected with a spring 20 sequentially with the metal rod 30, the outside force is inwardly acted on the two metal rods 11 and 12, and the spring is drawn and produces the elasticity, thus reaching the purpose of exercising. The spring 20 can be added or dismantled freely, thereby controlling the force degree of the arm-strength device and providing scientific and suitable force for exercising.
Description
Technical field
The utility model relates to a kind of chest-developer, particularly relates to the degree of control and the chest-developer that security performance is high of a kind of energy.
Background technology
Chest-developer is one of fitness equipment of using always of people, and normal use can make muscle flexibly vigorous and graceful.Traditional chest-developer adds two handles by one section big straight both ends of the spring and forms.Grab chest-developer two ends handle during use and inwardly exert oneself, cause spring bending and produce elastic force and reach the exercise purpose.Obviously, single spring can't be regulated and control the elastic force size adapting to the difference of each user's dynamics, and spring recuperation angle changes excessively during use, and screen resilience strengthens, and be too quickly very easily injured if sliding hand returns power.
Summary of the invention
The utility model is intended to overcome the defective of existing chest-developer and a kind of random chest-developer of the degree of control in use is provided, so that the convenience that is more suitable for taking exercise is provided for the user.For achieving the above object, the utility model provides changeable spring number to come the chest-developer of strength of adjustment, this chest-developer basic structure is the hinged two sections metal bars 11 of homonymy in the middle of one section metal bar 30,12, two metal bar length are identical, metal bar 11,12 other two ends can be swung at grade, metal bar 30 connects spring successively to two ends from the centre, spring length increases successively one by one, each limit five springs arranged side by side, totally ten springs, each spring other end connects metal bar 11 side by side, 12, form the equal counter stress of five springs in every limit, grab metal bar 11,12 two ends handles are inwardly exerted pressure and all springs elongated and generation elastic force, thereby reach the exercise purpose.
Good effect of the present utility model is, it overcome existing chest-developer structure single unreasonable, use defective such as inconvenience.By with spring segmentation, can freely increase and decrease number of springs during use and select optimal dynamics, thereby reach best train on; Spring than slice is easier to produce and install than thick spring, and is safer again during use, smart the wanting of more reasonable structure that allows chest-developer.Thereby both made things convenient for the user, reduced production cost again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Consult Fig. 1, the chest-developer of the energy degree of control of the present utility model comprises the metal bar 30 resistance handles of two metal bars, 11,12 handles and hinged spring 20.Main points of the present utility model are, two chest-developers, 11,12 1 ends are articulated in homonymies in the middle of the metal bar 30, equate that in two the acute angle places connect upper spring 20 side by side as figure, and spring 20 increases by five respectively on both sides, totally ten springs successively from the centre to two ends length.Metal bar 11,12 relies on fixed endpoint activity at grade.Spring 20 elongates when external force causes metal bar 11,12 two ends close, and spring 20 restored when external force disappeared.
Claims (3)
1, a kind of novel chest-developer of the energy degree of control, comprise two metal bars (11,12) handle and the metal bar (30) that is used for hinged spring (20), it is characterized in that, the hinged last two live metal rods of homonymy (11,12) in the middle of the metal bar (30), two metal bars (11,12) and metal bar (30) hinged spring arranged side by side (20), increase length one by one from the centre to the two ends spring, every spring can freely increase dress or tear open and subtract, and external force acts on then spring telescopic variation thereupon of metal bar (11,12).
2, the novel chest-developer of a kind of energy degree of control according to claim 1, it is characterized in that described metal bar (11,12) is movable handle, two handle length are identical, each end is articulated in the middle homonymy of another metal bar (30), its with metal bar (30) between be connected spring (20) side by side.
3, the novel chest-developer of a kind of energy degree of control according to claim 2, it is characterized in that, described spring is articulated between metal bar (30) and two metal bars (11,12) side by side, spring increases length successively from inside to outside, both sides number of springs, length correspondent equal, every spring can freely assemble or remove.
