Abstract
The utility model provides a treadmill motion buffer, including the rocker bar bearing, the footboard of running, spring and spring depression bar, one end and the rocker bar bearing of footboard of running is articulated, this buffer still includes the connecting rod and makes its the only left fixing support and right fixing support of acceptor level direction power for limited spring, the other end of footboard and the one end of connecting rod of running articulates, the other end of connecting rod is articulated with the one end of spring depression bar, spring depression bar order in proper order passes right fixing support, spring and left fixing support, the one end of spring sets firmly on the spring depression bar, the other end contacts with left fixing support, bear at the footboard under the state of effort, this effort passes through the connecting rod and transmits for the spring depression bar, and driving spring depression bar fixing support one side left removes and the motion buffering of compression spring with the footboard of realizing running. The utility model discloses an advantage lies in, turns into the horizontal force with gravity, and the spring only bears pressure, does not hold the flexural square, improves the life of spring by a wide margin.
Description
Technical field
The utility model relates to body-building apparatus technical field, particularly relates to a kind of treadmill motion buffer unit.
Background technology
Along with growth in the living standard, people are day by day urgent to the pursuit of health, and the investment that people spend in health also constantly increases.Treadmill, as one of the most effective body-building apparatus of one, enters average family, and becomes one of gymnasium standard facility.Although kind and the model of current treadmill are various, the general principle of mechanical part is but substantially identical with structure, and difference is on the controlling functions that electronic-controlled installation realizes variant.Current people have not been be satisfied with can run, to count or in the variation of function to the demand of treadmill, but focus on the outward appearance of product, quality, quality and comfortableness etc. more.Therefore in the design of the frame for movement of product, should more trend towards rational in infrastructure, be connected firmly, the durable and good reliability of part, man-machine efficacy is good, level of comfort is high, namely the update of product will adapt with the ever-increasing real needs of people.
Buffer system is the critical component of treadmill, and its function is the body wt supporting runner, alleviates the direct impact that kinematic mount causes in the face of human knee and leg joint.The athletic posture that good buffer system can make human body keep correct, and avoid the impact wear of joint part, improve the comfortableness of motion; And the ability that buffer system has the reliability of good motion, part parts have high antifatigue deformation and fracture.
The structure of the buffer system of the treadmill sold in the market as shown in Figure 1.
The advantage of this old structure is: by rocker bar bearing moving up and down pedal, change side-to-side movement into.Spring is laterally placed, but not stands to placement, so greatly saves space, makes pedal overhead comparatively closely, make runner feel more to run as on level land.But this structure also has obvious defect: the pressure that spring is subject to not with the dead in line of spring, but certain angle that tilts, this pressure can resolve into and being separated and the component vertical with axle of spring of axis being parallel of paralysing.Parallel component makes spring-compressed, and vertical stress component makes spring generation bending.Result is that the buffering effect of spring is poor, and loses efficacy very soon.
Utility model content
The utility model is mainly for solving above-mentioned Problems existing, and provide a kind of treadmill motion buffer unit, the spring of this buffer unit only bears the power of horizontal direction, significantly improves the service life of spring.
For solving above-mentioned Problems existing, the technical scheme that the utility model adopts is: a kind of treadmill motion buffer unit, comprise rocker bar bearing, running pedal, spring and spring pressure bar, one end and the rocker bar bearing of described running pedal are hinged, also comprise connecting rod and make its left hold-down support only bearing horizontal direction power and right hold-down support in order to restraining spring, the other end of described running pedal and one end of connecting rod hinged, the other end of connecting rod and one end of spring pressure bar hinged, spring pressure bar passes through right hold-down support successively, spring and left hold-down support, one end of spring is installed on spring pressure bar, the other end contacts with left hold-down support, under the state that pedal bears active force, this active force passes to spring pressure bar by connecting rod, driving spring depression bar left hold-down support side move and Compress Spring with realize running pedal motion buffering.
Described both ends of the spring is connected with left hold-down support and spring pressure bar respectively by cushion pad.
Described cushion pad offers some through holes.
The beneficial effect that the utility model brings is:
1, gravity is converted into horizontal force by the utility model, and spring only bears pressure, does not bear moment of flexure, significantly improves the service life of spring.Force and motion transmission is steady, and user feels more comfortable.
2, stressed member intensity is high, and structure is simple, and being convenient to processing and manufacturing, I& M, is the upgraded product of treadmill motion buffer unit, can create significant economic benefit to manufacturing enterprise.

Mark in figure: 1, rocker bar bearing, 2, running pedal, 3, left hold-down support, 4, spring, 5, spring pressure bar, 6, right hold-down support, 7, connecting rod.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in the figure, a kind of treadmill motion buffer unit, comprise rocker bar bearing 1, running pedal 2, spring 4 and spring pressure bar 5, one end and the rocker bar bearing 1 of described running pedal 2 are hinged, also comprise connecting rod 7 and make its left hold-down support 3 only bearing horizontal direction power and right hold-down support 6 in order to restraining spring, the other end of described running pedal 2 and one end of connecting rod 7 hinged, the other end of connecting rod 7 and one end of spring pressure bar 5 hinged, spring pressure bar 5 passes through right hold-down support 6 successively, spring 4 and left hold-down support 3, one end of spring 4 is installed on spring pressure bar 5, the other end contacts with left hold-down support 3, under the state that pedal bears active force, this active force passes to spring pressure bar by connecting rod, driving spring depression bar left hold-down support 3 side move and Compress Spring with realize running pedal 2 motion buffering, when leaving pedal, distress resolves, spring elongates, promotes spring push-rod to right translation.Spring pressure bar promotes connecting rod, and connecting rod promotes pedal and resets.The stroke so just completing a pedal pressure and upspring.
Described spring 4 two ends are connected with left hold-down support 3 and spring pressure bar 7 respectively by cushion pad.
Described cushion pad offers some through holes.
Operation principle: runner moves on pedal, press pedal when moving downward, pedal can rotate clockwise around rocker bar bearing axle.Pedal drives spring pressure bar Compress Spring by connecting rod, makes spring contraction, thus plays cushioning effect.When runner's health leaves pedal, spring elongates, promotes pedal and rotates counterclockwise around hinge making axle, thus pedal is risen.
