Treadmill folding mechanism

The present invention provides a treadmill folding mechanism, in particular, a loose fit assembly tolerance is not required, and the second sliding unit through the hand-holding mechanism is extended or shortened in the first sliding unit opposite to the pedal platform, so that the whole The height is effectively reduced after being folded and stored, thereby achieving the effects of simple structure, easy assembly, and low cost.

According to the vigorous development of industry and commerce, there is a widespread lack of exercise in modern people, leading to increased opportunities for diseases such as hypertension, diabetes, heart disease, obesity and poor physical fitness. Only regular exercise, strengthening heart and lung function In order to maintain the best physical fitness, coupled with the modern people's emphasis on daily health and leisure and sports, fitness equipment has gradually spread from the fitness center to the general family.

In addition, electric treadmills are the most common among fitness equipment, and cardio endurance training can be performed by the adjustable running speed and slope elevation angle of the electric treadmill. In recent years, it has been widely used by medical practitioners for patients. Physical fitness test and rehabilitation function, while the treadmill slope elevation angle adjustment can be divided into manual and electric type by driving source judgment, and can be divided into front elevation angle and back elevation angle adjustment according to the mechanism configuration mode, wherein the front elevation angle adjustment can be Divided into linear adjustment, splicing angle adjustment and cantilever splicing adjustment, this elevation control function is designed to allow the user to simulate the situation of up and down slope while running.

However, the frontal angle adjustment operation principle of the treadmill is to add an elevation control motor to the front end of the treadmill, and to change the elevation angle of the running board by driving the shaft to extend or shorten when the motor rotates, or to use the two sides of the armrest mechanism. The inner and outer sliding sleeves are linearly adjusted for relative elongation or shortening. However, such a structural design must be precisely matched to the assembly angle to accurately control the elevation angle of the running board to simulate the situation of ups and downs, and The tolerance requirements of the components are high, not only the components are complicated, the cost can not be effectively reduced, and the assembly alignment needs to be very precise and inconvenient and difficult, resulting in the overall cost becoming quite high, not all users have the willingness to purchase Necessity; in addition, the components of the treadmill are fixed in size and difficult to fold and store, so that when multiple treadmills are transported, they need to be disassembled and transported separately before being assembled separately, which not only causes difficulty in handling multiple treadmills. Increase, and relatively increase the labor and cost of packing freight and assembly, and those who have yet to work in this industry Meter to be effectively addressed.

Therefore, in view of the problems and shortcomings of the above-mentioned treadmills, the creators have collected and collected relevant materials through multi-party evaluation and consideration, and have continuously tried and modified the years of research and development experience in this industry, and designed a new type of folding mechanism for such treadmills. Born.
