Description

Technical Field

[0001] The utility model relates to the technical field of elliptical machine lifting, in particular to an electric lifting device for an elliptical machine track. Background Technique

[0002] The elliptical machine, also known as the space walker, is a very good device for cardiopulmonary function exercise and is loved by many users and professionals. The slope design, resistance adjustment function, programmed exercise modes, and the ability to specifically exercise certain tissues and muscles in the lower limbs of the elliptical machine make it a common exercise device in professional gyms and home living rooms. Although there are certain differences in the quality and exercise comfort of different types of elliptical machines, this machine is undoubtedly a powerful weapon for exercisers to carry out cardiopulmonary function exercise.

[0003] The existing patent with the publication number CN206355502U discloses a manual lifting structure of an elliptical machine, which is characterized by including a sliding bracket and a lifting component arranged on the base of the elliptical machine. The sliding bracket is axially connected to the base. The lifting component includes an outer telescopic tube, an inner telescopic tube, a positioning shaft and a spring. The lower end of the outer telescopic tube is axially connected to the base. The inner telescopic tube is arranged inside the outer telescopic tube and is in sliding fit with it. The upper end of the inner telescopic tube is axially connected to the sliding bracket. A gear position through groove is opened at the upper end of the outer telescopic tube. A plurality of clamping grooves are arranged in the direction close to the front end of the outer telescopic tube in the gear position through groove. A connecting long hole is opened on the inner telescopic tube. The positioning shaft passes through the connecting long hole and is in clamping fit with the clamping groove. The front end of the spring is sleeved on the positioning shaft, and the rear end of the spring abuts against the inner wall of the rear end of the outer telescopic tube. The advantage is that a lifting component capable of adjusting the movement track of the elliptical machine is added to the base of the elliptical machine, and different people can adjust the movement track of the elliptical machine according to the actual situation, and the practicability is strong.
