Description
Technical field
It the utility model is related to body-building apparatus technical field, more particularly to a kind of adjustable fitness equipment of crank up radius
Material.
Background technology
The crank up radius of current market sales of body-building apparatus, especially elliptical exercise machine equipment be all it is fixed,
No matter user's step size is caused all to use changeless stride, it is impossible to meet the demand for experience of different stride users.
Utility model content
Therefore, technical problem to be solved in the utility model is：A kind of adjustable body-building of crank up radius is provided
Equipment so that body-building apparatus crank up radius can be adjusted according to user's step size, to meet different stride users
Demand for experience.
Then, the utility model provides a kind of adjustable body-building apparatus of crank up radius, including crank, Yi Jiyu
The roller tube of crank connection, the other end of crank shaft core offer groove profile through hole, and roller tube assembly wears via height and can adjust
Ground is fixedly connected with crank, and bearing is provided with roller tube assembly, and roller tube is arranged on bearing.
Wherein, through hole and roller tube assembly the engagement connection.
One is set to be used to controlling the engagement of roller tube assembly and through hole and the knob that separates and be easy in roller tube assembly
Adjust roller tube assembly and the sliding shoe of via height position.
The adjustable body-building apparatus of crank up radius described in the utility model, by opening up groove profile through hole on crank,
Roller tube assembly is worn into through hole, makes the height adjustable of roller tube assembly in through-holes save land to be fixedly connected with crank, and will
Roller tube is arranged on the mode in the bearing in roller tube assembly, realizes the radius of gyration of crank and can adjust, and then meets
The demand for experience of different stride users.

Embodiment
Below, the utility model is described in detail with reference to accompanying drawing.
As shown in Fig. 1 to 5, a kind of adjustable body-building apparatus 1 of crank up radius, the fitness equipment are present embodiments provided
Material 1 includes：Crank 11, roller tube assembly 12 and roller tube 13.
Wherein, the other end in the axle center of crank 11 offers groove profile through hole 14, and roller tube assembly 12 wears the height of through hole 14
Adjustably it is fixedly connected with crank 11, bearing is provided with roller tube assembly 12（Do not identified in figure）, roller tube 13 is arranged on
On bearing.
In the present embodiment, through hole 14 and roller tube assembly 12 are connected using engagement.Therefore, set in roller tube assembly 12
One is used to controlling roller tube assembly 12 and through hole 14 to engage and the knob 15 that separates and be easy to adjust roller tube assembly 12 and lead to
The sliding shoe 16 of the height and position of hole 14.During locking knob 15, roller tube assembly 12 engages with through hole 14, when unclamping knob 15, rolling
Wheel tube assembly 12 separates with through hole 14, and when roller tube assembly 12 separates with through hole 14, roller tube assembly 12 can in through hole 14
To slide up and down, and then throw of crankshaft is adjusted, due to being connected between crank 11 and roller tube 13 by roller tube assembly 12, therefore
Can adjust for throw of crankshaft, realizes the regulation of body-building apparatus stride, and then meet the demand for experience of different stride users.
As shown in fig. 6, when roller tube assembly 12 is below through hole 14, throw of crankshaft R1, when roller tube assembly 12 exists
During 14 top of through hole, throw of crankshaft R2, R1 are more than R2.Therefore the stride regulation of body-building apparatus, passes through the adjustable of throw of crankshaft
Section is achieved.
In summary, the adjustable body-building apparatus of crank up radius described in the present embodiment, by opening up groove on crank
Type through hole, roller tube assembly is worn into through hole, makes the height adjustable of roller tube assembly in through-holes save land to be fixedly connected with crank,
And the mode being arranged on roller tube in the bearing in roller tube assembly, realizing the radius of gyration of crank can be adjusted, and be entered
And meet the demand for experience of different stride users.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
