[0003] However, the above solution cannot control the forward movement of the abdominal wheel, and has poor controllability. Utility Model Content

[0004] The utility model aims to provide a brakeable abdominal wheel which can control the forward travel of the abdominal wheel.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A brakeable abdominal wheel comprises an elbow support component, a running wheel and an armrest, wherein the running wheel is rotatably arranged at the bottom of the elbow support component, and the armrest is arranged on the elbow support component. The invention is characterized in that: it also comprises a brake mechanism, the brake mechanism comprises an operating member, a brake line and a brake pad, the operating member is arranged on the armrest, the brake pad is arranged at the bottom of the elbow support component opposite to the running wheel, the brake line is connected between the operating member and the brake pad, and the operating member can drive the brake pad to frictionally contact with the running wheel through the brake line to limit the rotation of the running wheel. In this way, the user can operate the operating member to control the brake of the abdominal wheel in the process of pushing the abdominal wheel forward according to his own situation during exercise, so as to prevent difficulty in getting up due to exhaustion or insufficient strength. The safety and operability are high, and the exercise intensity can be controlled.

[0007] The brake line includes a line body and a tubular shell, the line body passes through the tubular shell, the armrest is provided with a first limiting structure for limiting the movement of one end of the tubular shell, and the elbow support component is provided with a second limiting structure for limiting the movement of the other end of the tubular shell, one end of the line body is connected to the operating part, and the other end is connected to the brake pad, so that the tubular shell will be limited by the first limiting structure and the second limiting structure, and when operating the operating part, only the line body will be dragged to move, and the line body will not be exposed to the outside and is not easily damaged.

[0008] The armrest is a tubular body, and the operating member includes a handle rotatably arranged on the upper end of the armrest. The tubular shell is partially sleeved on the armrest, and one end of the wire body is connected to the handle. When the handle is pressed and rotated, one end of the wire body can be dragged to move so that the other end of the wire body pulls the brake pad. The brake pad is deformed by the pulling and comes into friction contact with the walking wheel. When the user bends over to do abdominal exercises by sliding back and forth, the user can hold the armrests with both hands to conveniently operate the handle to control the friction braking of the brake pad and the walking wheel.

[0009] The first limiting structure is a limiting sleeve sleeved on the upper end of the armrest, and the limiting sleeve is formed with a first clearance hole for the wire body to pass through and limit the tubular shell to pass through. The wire body passes through the limiting sleeve but the tubular shell cannot pass through, so that the wire body can be smoothly connected to the operating member.

[0010] The second limiting structure is a limiting seat arranged at the bottom of the elbow support component, and the limiting seat is formed with a second clearance hole for the wire body to pass through and limit the tubular shell to pass through. The wire body passes through the limiting seat but the tubular shell cannot pass through, so that the wire body can be smoothly connected to the brake pad.

[0011] The brake pad is a deformable metal, and the outer peripheral surface of the running wheel is provided with an elastically deformable polymer layer. The brake pad can be deformed and come into frictional contact with the running wheel. The elastically deformable polymer layer provided on the outer peripheral surface of the running wheel cooperates with the brake pad to increase friction, making the brakes more sensitive and reducing the noise generated by friction.

[0012] The device also includes a steering wheel, a wheel frame and an adapter. The steering wheel can be rotatably arranged on the wheel frame, and the adapter can be rotatably arranged on the wheel frame around a first axis extending up and down. The elbow support component can be rotatably connected to the adapter around a second axis extending front and back. A driving part is arranged at the bottom of the elbow support component. When the elbow support component rotates and tilts around the second axis, the driving part can drive the wheel frame to rotate around the first axis. In this way, when exercising, the user can drive the wheel frame to rotate by tilting and pressing down the abdominal wheel, and the steering wheel will rotate accordingly. Pushing the abdominal wheel forward will become an arc-shaped steering movement, which can well exercise the user's side abdominal muscles.

[0013] The driving part includes two first driving surfaces arranged left and right and inclined up and down or extending in an arc shape up and down. The wheel frame is provided with two second driving surfaces that can be matched with the two first driving surfaces. The arrangement is such that when the elbow support component rotates and tilts around the second axis, the first driving surface moves downward and cooperates with the second driving surface to drive the wheel frame to rotate around the first axis, so that the abdominal wheel turns toward the inclined side of the elbow support component. In this way, the wheel frame will be driven to rotate by the first driving part that is tilted downward, and the abdominal wheel can turn.

[0014] A first elastic reset member is arranged between the adapter and the elbow support member, and the first elastic reset member drives the elbow support member to return to a horizontal state. The first elastic reset member includes two coil springs, and the two coil springs are respectively arranged on the left and right sides of the adapter. One end of the coil spring is pressed against the adapter, and the other end is pressed against the elbow support member. In this way, when the abdominal wheel tilts to one side, the coil spring on one side can drive the abdominal wheel to return to a horizontal state.

[0015] A second elastic reset member is arranged between the adapter and the wheel frame, and the second elastic reset member drives the wheel frame to reset to an initial position.

[0016] The second elastic reset member includes a left torsion spring and a right torsion spring distributed on the left and right sides. The left torsion spring and the right torsion spring both include a spiral body installed at the bottom of the elbow support component and two force-bearing sections extending outward from the spiral body. One force-bearing section of the left torsion spring and the right torsion spring are connected to each other, and the other force-bearing section rests on the wheel frame. When the wheel frame rotates to one side, the left torsion spring and the right torsion spring are driven to be deformed under force. The left torsion spring and the right torsion spring can drive the wheel frame to reset to its initial position. BRIEF DESCRIPTION OF THE DRAWINGS

At the end, when the wheel frame 51 rotates toward one side, the left torsion spring 161 or the right torsion spring 162 is driven to deform under force. For example, when the wheel frame 51 rotates toward the left side, the left torsion spring 161 can be driven to deform under force. When the force driving the wheel frame 51 to rotate disappears, the left torsion spring 161 or the right torsion spring 162 can drive the wheel frame to return to its initial position. Two mounting columns 17 and two anti-detachment gaskets 171 distributed on the left and right are provided at the bottom of the elbow support component 1. The two anti-detachment gaskets 17 and the two mounting columns 17 are fixed to the two mounting columns 17 by bolts.
