Description

Elliptical machine stride adjustable structure

Technical field

This utility model relates to a kind of fitness equipment, particularly relates to a kind of elliptical machine stride adjustable structure.

Background technology

Elliptical machine is again spacewalk machine, and as one for the good apparatus of cardio-pulmonary function train on, it is liked by many user and professional person.The slope design of elliptical machine, resistance opposing regulatory function, programmed motor pattern and the ability specially performed physical exercise lower limb tissue muscle allow it become sports apparatus common in professional gymnasium and keeping room.When the feature of elliptical machine maximum is exactly its exercise of human body utilization, knee joint is to there is not force.Employing elliptical machine is taken exercise, and can not only prevent, reduces, alleviate cervical spondylosis, scapulohumeral periarthritis and the pain at upper back, and produced impulsive force when avoiding running, preferably protect joint, thus possess more preferable safety coefficient.Oval functional gymnastics and the sciatic regulation of stimulation, strengthen endurance and the strength of waist muscle, for buttocks, thigh, side waist and the stimulation of lower abdomen, reaches the effect of body shaping. Traditional elliptical machine stride is fixing, it is impossible to according to the different heights of person taking exercise, that lower limb length adjusts stride, comfortableness and adaptability is poor.

Summary of the invention

The purpose of this utility model is that providing a kind of uses the most comfortable, can to meet more crowd demand elliptical machine stride adjustable structure.

For achieving the above object, technical solution of the present utility model is:

This utility model is a kind of elliptical machine stride adjustable structure, including body frame, handle, front swing pipe, foot tube, rear swing pipe, pedal, stride adjusting part；The lower end of described handle is by the upper end thereof of handle connecting plate with front swing pipe, and the middle part of front swing pipe is hinged with body frame by front swing pipe connecting plate, and the lower end of front swing pipe is hinged with the inner of foot tube, and the outer end of foot tube is hinged with the bottom surface of pedal；

Described stride adjusting part includes movement locus pipe, swing arm, roller；The front portion of described movement locus pipe has a camber line gathering sill, this camber line gathering sill is slidably socketed on roller, roller is rotatably mounted to the outer end of swing arm, and the inner of swing arm is fixedly sleeved on the axis of flywheel, and the rear end of movement locus pipe is hinged with body frame by rear swing pipe.

This utility model also includes a bearing pin, and this bearing pin is located on the stage casing of foot tube and the stage casing of movement locus pipe.

After using such scheme, owing to this utility model is additionally arranged stride adjusting part, the roller in movement locus Guan Keyu swing arm in this stride adjusting part slips and produces relative movement, form the movable length that movement locus pipe is different, thus reach to regulate the purpose of stride, have and use advantage the most comfortable, that more crowd demand can be met.

With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention

As shown in Figure 4, Figure 5, this utility model is a kind of elliptical machine stride adjustable structure, including body frame 1, handle 2, front swing pipe 3, foot tube 4, rear swing pipe 5, bearing pin 6, pedal 7, stride adjusting part 8.

The lower end of described handle 2 is by the upper end thereof of handle connecting plate 21 with front swing pipe 3, and the middle part of front swing pipe 3 is hinged with body frame 1 by front swing pipe connecting plate 31, and the lower end of front swing pipe 3 is hinged with the inner of foot tube 4, and the outer end of foot tube 4 is hinged with the bottom surface of pedal 7.

As shown in Figure 1-Figure 3, described stride adjusting part 8 includes movement locus pipe 81, swing arm 82, roller 83.The front portion of described movement locus pipe 81 has a camber line gathering sill 811, this camber line gathering sill 811 is slidably socketed on roller 83, roller 83 is rotatably mounted to the outer end of swing arm 82, the inner of swing arm 82 is fixedly sleeved on the axis of flywheel 9, and the rear end of movement locus pipe 81 is by rear swing pipe 5 with body frame 1(as shown in Figure 4) hinged.

Shown in Fig. 3, described bearing pin 6 is located on the stage casing of foot tube 4 and the stage casing of movement locus pipe 81, and both is coupled together so that foot tube 4 is synchronized with the movement with movement locus pipe 81.

Operation principle of the present utility model:

As shown in Figure 4, Figure 5, after pedal 7 is depressed, pedal 7 can be linked with handle 2 by foot tube 4, front swing pipe 3, simultaneously, pedal 7 can drive movement locus pipe 81 front portion to slide along roller 83, during sliding, this utility model utilizes different fulcrums on two movement locus pipe circular arcs to form range difference, form many strides switching of minimum zero (as shown in Figure 1) to maximum 100 centimetres (as shown in Figure 2), reach the optimization of man machine environment system's overall performance, thus reach to regulate the purpose of stride.

Emphasis of the present utility model is that and is provided with stride adjusting part.

The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
