Abdominal wheel with controllable travel distance

Abstract

The invention discloses an abdominal wheel with the controllable travel distance. The abdominal wheel comprises handles, a center shaft, a first end cover, a second end cover and wheel body, the first end cover and the second end cover are integrated with the wheel body and wavily arranged on the center shaft, the handles are correspondingly connected to the two ends of the center shaft, a connecting shaft sleeve is fixed to the center shaft, at least one group of elastic damping devices are mounted on one side of the connecting shaft sleeve, a sliding shaft sleeve is arranged on the other side of the connecting shaft sleeve, a limiting sleeve capable of sliding in the axial direction is arranged on the sliding shaft sleeve, a travel distance locating seat sleeves the limiting sleeve, the travel distance locating seat is fixed to a middle division plate, the travel distance locating seat is provided with a rotary guide rail groove, and a rotary guide rail matched with the rotary guide rail groove is arranged on the limiting sleeve; and in the initial state, the locating end of the rotary guide rail is matched with the initial limiting end of the rotary guide rail groove to limit. The abdominal wheel has the advantages that the structure is simple, the operation is convenient, damping is adjustable, the travel distance is controllable, and training is safe after the structure is adopted.

Description

technical field [0001] The invention relates to a kind of exercise and fitness equipment, in particular to an ab wheel with controllable stroke, which has a set maximum motion stroke and an adjustable damping force. Background technique [0002] With people's emphasis on physical fitness and the improvement of exercise awareness, many people have begun to invest in indoor fitness activities, and indoor exercise and fitness equipment has developed rapidly. The abdominal wheel is one of the more popular sports and fitness equipment. The abdominal wheel is a small fitness equipment that can exercise muscles, joints, and lose weight. Because it is durable, easy to use, and the required venue is relatively simple, etc. Because of its advantages, it is deeply loved by the majority of fitness trainers. However, the existing abdominal wheel has the following problems in use: First, because there is no damping and stroke control, it is easy to lose control during abdominal training,...

AI Technical Summary

Problems solved by technology

However, the existing abdominal wheel has the following problems in use: First, because there is no damping and stroke control, it is easy to lose control during abdominal training, especially for beginners or trainers with poor strength control, it is easy to lose control due to wheel speed. Excessive speed can cause muscle strain or bumps to cause facial injuries, which poses a safety hazard during fitness exercises

The second is that even if there is a torsion spring abdominal wheel, its torque output is not stable, there is no resistance adjustment and stroke adjustment function, it is difficult to meet the needs of different users in various training stages

The third is that there is no counting and timing function, and the calorie consumption cannot be recorded, which brings inconvenience to the reasonable arrangement of exercise.

The four handles cannot be disassembled, the packaging and transportation are bulky, and storage is inconvenient

In response to the above problems, many manufacturers and people of insight have carried out development and trial production, but so far no ideal products have come out
