Description
Technical field
The present invention relates to body-building apparatus technical field, more particularly to a kind of chest expander of convenient regulation.
Background technology
Present fast pace life, operating pressure is increasing, and body does not catch up with the demand of Working Life but, and lacks suitable
When outdoor exercises, there is inferior health or unhealthy situation in many people, and therefore, people would generally arrive gymnasium or borrow at home
Fitness equipment is helped to reach the purpose of sport and body-building.The different parts that can cause body by using different body-building apparatus are had
The exercise of effect, to reach body-building effect.
The size of the chest expander of existing physical training is all universal size, but for all ages and classes level, no
The crowd of same height, when being taken exercises using chest expander, there is different difference, chest expander can not be adjusted in itself
Carry out the difference of adaptation population, be also exactly the regulation of chest expander pulling force, what is relied primarily on is the quantity of spring, it is impossible to does its other party
The adjustment of formula, and the chest expander of existing pedal, too complicated in structure, cost is higher.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of of proposition facilitates the pulling force adjusted
Device.
To achieve these goals, present invention employs following technical scheme：A kind of chest expander of convenient regulation, including the
One handle, second handle and spring, one end of the first handle lead to heart circular hole and are socketed with the first round bar, the first handle
The other end annulus is connected with by link, be socketed with rotating shaft on the annulus, and the taper end of rotating shaft screw be connected with it is elastic
Adjuster, flat rope being enclosed with the rotating shaft and is connected with draw ring, the first circular hole, first circle are equidistantly offered on the draw ring
Hole is connected by spring with equidistant second circular hole opened up on second handle, and the other end of the second handle leads to the socket of heart circular hole
There is the connection of the second round bar.
As further describing for above-mentioned technical proposal：
Fixed after the flat rope winding annulus by rivet.
As further describing for above-mentioned technical proposal：
First circular hole is identical with the diameter of the second circular hole.
As further describing for above-mentioned technical proposal：
First round bar and first handle are demountable structure.
As further describing for above-mentioned technical proposal：
Second round bar and second handle are demountable structure.
As further describing for above-mentioned technical proposal：
The first handle, link and annulus are integral type structure.
In the present invention, first, by flat rope and the combination of rotating shaft, user can be according to the actual height and arm of oneself
Long condition, shunk by rotating shaft, extend flat rope to meet the needs of itself exercise, so solve Different Individual difference
People, using chest expander the drawbacks of；Secondly, user when in use, by adjusting the length of flat rope, when exercise due to
The position that arm stretches when originating is different, changes the intensity of pulling force, is so easy to user to adjust training strength, practicality at any time
By force；Finally, the combination of the handle using dismountable round bar and with through hole, meet that people are actually needed according to itself, change
Structure, enter to travel far and wide and step on the lower end of chest expander, the upper end of hand-held chest expander is performed physical exercise with chest expander, this simple in construction, operation
It is convenient, reduce the purchase cost of user.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Reference picture 1-3, a kind of chest expander of convenient regulation, including first handle 2, second handle 12 and spring 10, first
One end of handle 2 leads to heart circular hole and is socketed with the first round bar 1, and the other end of first handle 2 is connected with annulus by link 7
14, rotating shaft 8 is socketed with annulus 14, and the taper end of rotating shaft 8 is screwed and is connected with slack adjuster 3, and flat rope 4 is enclosed with rotating shaft 8
It is connected with draw ring 6, the first circular hole 9 is equidistantly offered on draw ring 6, the first circular hole 9 is by spring 10 with being opened up on second handle 12
Equidistant second circular hole 11 connect, the other end of second handle 12, which leads to heart circular hole and is socketed with the second round bar 13, to be connected.
Flat rope 4 is fixed after winding annulus 14 by rivet 5, and the first circular hole 9 is identical with the diameter of the second circular hole 11, the first circle
Bar 1 is demountable structure with first handle 2, and the second round bar 13 is demountable structure with second handle 12, first handle 2, is connected
Frame 7 and annulus 14 are integral type structure.
The effect of rotating shaft 8 is that the length of flat rope 4 is adjusted, and to meet the exercise needs of user, the taper end of rotating shaft 8 is led to
Annulus 14 is crossed until both ends are socketed in annulus 14, flat rope 4 is shunk by the butt end circular bosses of leakage, passes through pine
Tight adjuster 3 is fastened, and prevents that the revolution of rotating shaft 8 causes flat rope 4 to extend in exercise routine.
Operation principle：In use, when the stretching routine of user's two arms of progress, first slack adjuster 3 is loosened, led to
Flat rope 4 is retracted to most weakness by the round platform for crossing the butt end of rotating shaft 8, and two hands hold first handle 2 and second handle 12, stretching respectively
To suitable length, slack adjuster 3 is tightened, completes the adjustment to chest expander initial length；When user need to be carried out with chest expander
When up-down stretch is moved, the first round bar 1 is penetrated in the through hole of first handle 2, the second round bar 13 is then penetrated into second handle
In 12 through hole, the rear foot step on the second round bar 13, slack adjuster 3 is loosened, received flat rope 4 by the round platform of the butt end of rotating shaft 8
Most weakness is reduced to, two hands hold first handle 2 and second handle 12, are stretched to suitable length, tighten elastic regulation respectively
Device 3, the adjustment to chest expander initial length is completed, connect the spring 10 of varying number according to the practical capacity of user afterwards.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
