Lifting mechanism of running device

Abstract

The invention relates to the field of exercise equipment, in particular to a lifting mechanism of a running device, comprising a running platform lifting base, a stepping motor, a worm gear, synchronous belts, linear guide rails, a running platform fixing plate, a lifting sliding plate, a trapezoid lead screw, a trapezoid nut, lifting rods, a connection valve and a fixing rod. In the lifting mechanism, the lifting sliding plate moves along the linear guide rails, the accuracy is high and the operation is stable. Simultaneously, the lifting mechanism is provided with two lifting rods, the loadability is strong, the application group is wide, and the use is convenient.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a lifting mechanism of a treadmill. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people pay more and more attention to their own health. The fitness boom has been one wave after another, gradually transitioning from exercising in public gyms to building home gyms. Because of its simple form of exercise, the treadmill is often used as the first choice for families. It not only shields the limitations of the venue and environment, but also eliminates many obstacles to exercise. After years of development, it has accumulated a variety of running scene modes and intensity control programs, and Digital functions such as entertainment and Internet calls are gradually loaded, making it an important carrier for current running exercises. The treadmill adjusts the intensity of exercise by changing th...

Problems solved by technology

[0004] Searched by the Information Retrieval Center of the Patent Office of the State Intellectual Property Office, the closest existing technology is the invention application "Improved Treadmill Lifting and Adjusting Mechanism" filed by Wang Guoliang in 2002 with the publication number CN2507502Y, which uses a DC lifting motor to drive the screw rod. To achieve slope adjustment, its disadvantages are: direct current is prone to problems such as sudden surge and noise, which will cause sudden stop or speed up of the machine, difficulty in reversing the direction of the DC motor, and sparks, short life, and frequent maintenance

At the same time, the ability of the treadmill to bear the load has also been limited.

Among them, the close existing technology also has the utility model patent "Rear Powered Treadmill Lifting Mechanism" with the publication number CN201692564U applied by Shandong Huikang Sports Equipment Co., Ltd. in 2010, which discloses a treadmill with a negative angle The lifting mechanism of the power treadmill has the advantage of a large lifting angle, but the disadvantage is that the lifting speed does not change during the lifting process, especially when the slope is large, it is not safe to continue to adjust the slope quickly
