Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to an adjustable stepper. Background Art

[0002] Modern people pay more and more attention to body maintenance, and the most popular health care method is exercise. However, modern people are busy with work and live in crowded environments, so it is rather troublesome to find free time and a suitable place for exercise. Therefore, many fitness equipment have been introduced on the market for users to exercise at home, including steppers. A stepper is a common fitness equipment, which is easy to install, occupies a small area, is convenient for daily home use and storage, and can burn calories, increase heart rate and aerobic respiration ability. It uses the up-and-down swing of the left and right pedals to simulate stepping motions such as walking and climbing stairs, so as to train the leg muscles and achieve the effect of exercise. The structure of traditional steppers can only achieve simple stepping motions, and the exercise is relatively monotonous. Therefore, in order to enable the stepper to train other parts of the body as well, rotating steppers have emerged on the market, so that the stepper has the function of rotating and twisting the waist. However, the existing similar products only have one of the functions of up-and-down stepping or rotating stepping, and cannot switch between the two functions, resulting in a single function. Summary of the Utility Model

[0003] Aiming at the technical problems existing in the prior art, the utility model provides an adjustable stepper, which can realize the switching between the two functions of up-and-down stepping and rotating stepping, and can meet the different usage requirements of users.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an adjustable stepper, including a base, a rotating seat, a swinging frame and pedals. The rotating seat is rotatably connected to the base around its vertical axis. The swinging frame is swingably connected to the rotating seat, and the swinging frame has two upwardly extending ends. The pedals are respectively installed at the two ends of the swinging frame. The stepper further includes a connecting member. The base is provided with a rotation stopping connection portion and a rotation transmission portion. The connecting member can be detachably connected to one of the rotation stopping connection portion and the rotation transmission portion. When the connecting member is connected to the rotation stopping connection portion and is detachably connected to the rotating seat, the connecting member restricts the rotation of the rotating seat relative to the base. When the connecting member is connected to the rotation transmission portion and is detachably connected to the swinging frame, the connecting member drives the rotating seat to rotate relative to the base when the swinging frame swings up and down.

[0005] Further, the rotation transmission portion is a rotating member rotatably connected to the base, and the rotation axis of the rotating member is perpendicular to the rotation axis of the rotating seat.

[0006] Further, the rotating member includes a connecting rod and a rotating seat. The rotating seat is rotatably connected to the base, and the rotation axis of the rotating seat is perpendicular to the rotation axis of the rotating base. One end of the connecting rod is fixedly connected to the rotating seat, and the other end is rotatably connected to the swing frame and is used for detachably connecting to the connecting member.

[0007] Further, the base is provided with a connecting sleeve which extends along the direction of the rotation axis of the rotating seat. One end of the rotating seat is movably sleeved in the connecting sleeve, so that the rotating seat can rotate around the axis of the connecting sleeve and can slide along the axis direction of the connecting sleeve.

[0008] Further, the connecting member is detachably connected by plugging and matching with the rotary transmission part and the swing frame. The rotary transmission part is provided with a first jack for plugging the connecting member, and the swing frame is provided with a second jack for plugging the connecting member.

[0009] Further, the connecting member is detachably connected by plugging and matching with the anti-rotation connecting part and the rotating base. The anti-rotation connecting part is provided with a third jack for plugging the connecting member, and the rotating base is provided with a fourth jack for plugging the connecting member.

[0010] Further, the swing frame is in a V shape. The two sides corresponding to the V shape are respectively swing arms. The upper ends of the two swing arms respectively form the two ends of the swing frame. Oil cylinders are respectively connected between the two swing arms and the rotating base.

[0011] Further, U-shaped members are respectively connected to the upper ends of the two swing arms. One end of the oil cylinder is rotatably connected to the U-shaped member, and the other end of the oil cylinder is rotatably connected to the rotating base.

[0012] Further, balance connecting pieces are respectively provided corresponding to each pedal. One end of the balance connecting piece is rotatably connected to the corresponding pedal, and the other end is rotatably connected to the rotating base.

[0013] Further, a rotating shaft extending along the height direction is provided on the rotating base. The rotating shaft is rotatably connected to the base. A bearing is provided between the rotating shaft and the base.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The present utility model further includes a connecting member. The base is provided with a rotation-preventing connecting portion and a rotation transmission portion. The connecting member is detachably connected to one of the rotation-preventing connecting portion and the rotation transmission portion. When the connecting member is connected to the rotation-preventing connecting portion and is detachably connected to the rotating seat, the connecting member restricts the rotation of the rotating seat relative to the base. When the connecting member is connected to the rotation transmission portion and is detachably connected to the swing frame, the connecting member drives the rotating seat to rotate relative to the base when the swing frame swings up and down. With this structure of the present utility model, when the connecting member is connected to the rotation-preventing connecting portion and the rotating seat, the swing frame only swings up and down to simulate stepping motions such as brisk walking and going up stairs. When the connecting member is connected to the rotation transmission portion and the swing frame, the swing frame swings up and down and also rotates, so that the user can adjust the motion mode of the stepper according to his own needs, with diversified functions, achieving multi-faceted training and having sports fun.
