Description

A treadmill equipped with a flexible shock-absorbing device

technical field

The invention belongs to the field of fitness equipment, and in particular relates to a treadmill equipped with a flexible damping device.

Background technique

With the rapid development of social economy and culture, healthy life has been paid more and more attention by modern people. Among the various types of fitness equipment, treadmills have always been popular for their simple and efficient universal exercise methods. The electric treadmill drives the runway through the motor, so that people can run or walk passively at different speeds. Due to the passive formation of running and walking, from the appearance of the movement, it is almost the same as running or walking on the ground. But from the point of view of human body exertion, running and walking on an electric treadmill saves a stepping and stretching action compared to ordinary running and walking. It is this point that makes every person who exercises on the electric treadmill feel very relaxed. It can make people run about 1/3 more than ordinary running, and consume more energy than ordinary walking and running.

However, since the treadmill was born, there have always been problems such as poor shock absorption capacity and high noise, which has brought difficulties to the popularization of treadmills from gyms to ordinary people's homes. Some traditional treadmills also have shock-absorbing devices, but they are limited to setting small pieces of rubber pads or hard hollow air bags in the interlayer of the runway. These simple devices are not easily deformed by impact, and it is difficult to effectively absorb the impact of running. In the end, the force on the runway will completely react on the legs, causing vibration damage to the joint joints such as the user's ankles and knees. Moreover, because the existing treadmills cannot effectively absorb shocks, the movement noise is very large, especially in the use process of the floor residents, and the running exercise will bring great trouble to the surrounding neighbors.

Contents of the invention

The technical problem to be solved by the present invention is to provide a treadmill equipped with a flexible shock absorbing device, which can effectively reduce shock and noise.

The technical scheme adopted by the present invention to solve the technical problems is: provide a treadmill equipped with a flexible shock absorbing device, comprising a runway and a base, characterized in that an elastic member is installed at the front between the runway and the base, and Elastic stoppers are installed between them.

A treadmill equipped with a flexible damping device according to the present invention is characterized in that the elastic components include springs, elastic rubber blocks, elastic air bags or C-shaped spring sheets.

And because the impact force is fully absorbed, the vibration of the machine is reduced, and the movement noise is also reduced accordingly, which will not affect the surrounding living environment, which is conducive to the popularization of household treadmills.

2. The elastic parts can be springs, elastic rubber blocks, elastic airbags or C-shaped spring pieces, which can produce large elastic deformation and rebound quickly. After repeated tests by the applicant, the spring is the best elastic component. Not only is it deformed by force, it can quickly absorb the impact, and the rebound speed is fast. Even in fast-paced running, it can also maintain shock absorption. Abilities are constant and unaffected.

3. Install an elastic limit device between the runway and the base. The elastic limit device includes a slider and a chute. Install chutes on the two inner sides of the base close to the runway. Install sliders on both sides of the runway. The slider is inserted into the slide in the groove and can move along the chute. In this way, it can not only prevent the elastic parts from falling out when the runway is laid horizontally to be placed vertically, but also make the movement of the runway limited to swinging up and down, and will not shake left and right under the condition of uneven force, which will make the user unbalanced .

4. The bracket is in the shape of "匚". The cross bar of the bracket is hinged on the base. The two arms of the bracket are respectively hinged on both sides of the bottom surface of the runway. The elastic parts are installed between the bracket and the runway. This design can further ensure that the runway will not run There will be side to side shaking. Pulleys are installed on the rear bottom of the runway. During the running process, the runway will move forward and backward for a small distance. The pulleys can reduce the friction between the rear end of the runway and the ground, and can convert part of the impact force into the forward and backward movement of the runway to offset it. , play a role in further shock absorption.

5. The elastic limit device adopts a slide plate. The middle part of the slide plate is hinged on the support arm of the bracket. An arc-shaped hole is set on the upper end of the slide plate. Hinged screws are installed in the arc-shaped hole. The hinged screw connects the slide plate and the runway together, and rollers are installed at the end of the slide plate. ; The slideway is installed on the base in a way that the front is low and the rear is high, and the rollers are arranged on the slideway. When the user is running, the pressure is transmitted to the spring, the spring shrinks, and the hinged "X"-shaped bracket and the skateboard are also pressed down to deform, and the hinged screw moves in the arc-shaped hole, and part of the pressure is converted into the rolling wheel. The movement on the slideway absorbs the force instead of rebounding to the lower limbs of the human body, which further plays a good protective role. The slideway is installed in a way that the front is high and the rear is low, which can help the shock absorber to rebound quickly and avoid the jamming phenomenon. The hinged way between the various mechanisms ensures that the shock absorbing mechanism can effectively prevent the discomfort caused by the rigid contact to the human body.

6. The elastic part adopts a spring assembly. The spring assembly includes a spring, a spring base and a rubber sheath. The two ends of the spring are respectively equipped with cylindrical rubber sheaths. The rubber sheaths are respectively embedded in two spring bases, and one spring base is fixed on the At the bottom of the runway, another spring mount is mounted on a base or stand. The spring is embedded, easy to disassemble, and can be replaced in time if damaged. The rubber boot reduces frictional noise between the spring and the spring base. The two rubber sheaths set on a spring can be inserted and snapped together, which not only has a beautiful appearance, but also has an isolation function to prevent debris from being caught in the spring and causing damage. Moreover, the rubber sheath closely fits the outer circumference of the spring, which can avoid left and right shaking when the spring is under uneven force.

7. The device has simple structure, convenient manufacture, flexible and convenient use, good practical performance, and is suitable for popularization in the industry.
