Multi-level buffer structure for fitness running machine plate

Abstract

The invention discloses a multi-level buffer structure for a fitness running machine plate. The multi-level buffer structure comprises a body of a running machine, a running belt and a running plate are arranged on the body, a base is arranged at the bottom end of the body, rotating shafts and sliding rods are arranged at two ends of the base, the sliding rods are positioned on the outer sides of the rotating shafts, rotating rods arranged at two ends of each rotating shaft, rotating rod buffer devices are arranged on the rotating rods, rollers are arranged at the lower ends of the rotating rods, two sleeves are arranged on each sliding rod, a horizontal buffer spring is connected between two sleeves, two connecting seats are arranged on the body, the connecting rods are hinged to the lower ends of the two connecting seats and hinged to the sleeves, telescopic rods are arranged at two ends of the base, two telescopic holes are formed in the lower portion of each end of the body, and vertical buffer springs are arranged on the outer sides of the telescopic rods. According to the structure, multi-level buffer is achieved, multi-directional buffer damping is achieved, vibration sense is buffered layer by layer, the reverse impact force of the running machine on human bodies is decreased, and the pressure of knee joints and lumbar vertebras is relieved.

Description

technical field [0001] The invention relates to the field of treadmills, in particular to a multi-stage buffer structure for fitness treadmill boards. Background technique [0002] Treadmill is a common fitness equipment for families and gyms, and it is the simplest type of home fitness equipment today, and it is the best choice for home fitness equipment. Treadmills are divided into mechanical treadmills and electric treadmills. Mechanical treadmills are driven by the friction between the runner's feet and the running belt. Simply put, electric treadmills rely on motors to drive the running belt to run. Electric treadmills are gym And the more high-end equipment in the family, it drives the running belt through the motor to make people run or walk passively at different speeds. Due to the passive formation of running and walking, it is almost the same as running or walking on the ground from the perspective of movement shape, but from the perspective of human body strength...

AI Technical Summary

Problems solved by technology

This cushioning method cannot well disperse the impact of the treadmill running board on the knee joint, and there is a soft feeling when stepping on the running board, and the foot is not strong, which may easily cause the body to sway left and right, which is safe. If the running board of the treadmill is in a bent state for a long time, it will easily cause the running board to be deformed and the service life will be short
