Embodiment 1

[0028] A detailed description will be given below of specific embodiments of the present invention according to the accompanying drawings.

[0029] according to Figure 1-Figure 9 As shown, a kind of abdominal fitness equipment described in this embodiment includes a support tube 2 made of aluminum alloy, a speed change mechanism 3 and rollers arranged in pairs, and the rollers arranged in pairs are installed on the support tube; The speed change mechanism is installed between the paired rollers.

[0030] A polygonal positioning ring 20 is formed at the center of the outer wall of the support tube, a driven rotor 25 is installed at the center of the support tube, and a plurality of equidistant magnets b251 are evenly installed at one end of the driven rotor along the circumferential direction. Motors 24 are fixedly installed at both ends of the driven rotor inside the support tube, and the output shaft of the motor is connected to the driven rotor in rotation; a circuit board...

Embodiment 2

[0045] according to Figure 1-Figure 6 as well as Figure 10-Figure 12 As shown, a kind of abdominal fitness equipment described in this embodiment includes a support tube 2 made of aluminum alloy, a speed change mechanism 3 and rollers arranged in pairs, and the rollers arranged in pairs are installed on the support tube; The speed change mechanism is installed between the paired rollers.

[0046] A polygonal positioning ring 20 is formed at the center of the outer wall of the support tube, a driven rotor 25 is installed at the center of the support tube, and a plurality of equidistant magnets b251 are evenly installed at one end of the driven rotor along the circumferential direction. Motors 24 are fixedly installed at both ends of the driven rotor inside the support tube, and the output shaft of the motor is connected to the driven rotor in rotation; a circuit board 23 and a battery 22 are also fixedly installed inside the support tube , the motor and the storage battery ...

Embodiment 3

[0067] This embodiment also includes the following features on the basis of Embodiment 2, the handle 41 includes a spherical handle head and a handle body; the handle body includes a polished rod part and a threaded part, and the polished rod part and the wheel The body is rotated and connected, and is positioned on the wheel body through the crank head and the nut; the other wheel body is provided with a threaded hole on the circumference corresponding to the position of the rocker; when the present invention is used as an abdominal wheel, the threaded part Extend to the threaded hole of another wheel body, and this wheel body is threadedly connected, has reduced the length that described rocking handle stretches out of wheel body like this, reduces the hand that the rocking handle that stretches out when the user uses and acts on the support tube. , At the same time, the two wheel bodies are connected into one body to increase the stability of the structure.

Abstract

The invention discloses abdominal fitness equipment which comprises a supporting tube made of an aluminum alloy, a speed change mechanism and rollers in pairs, wherein the rollers in pairs are mountedon the supporting tube; and the speed change mechanism is arranged between the rollers in pairs. When an abdominal roller is used by a beginner, the speed change mechanism generates resistance in theforward pushing process, and the direction of holding the abdominal roller can be adjusted; when hand or abdominal strength reaches the limit and is not enough to support, a reverse button can be pressed down, a motor in the supporting tube runs, a driven rotor rotates, a magnet b on the driven rotor drives a magnet a on a ring gear to rotate, the ring gear is rotated to drive a gear b, a gear dis driven by a gear a, a gear c drives an internal gear on a transmission base to rotate, and the transmission base enables the roller to slow down to generate backward force so as to make the rollerreturn. Therefore, rotation of the roller is conveniently controlled, and the condition that pull of a user is caused by out-of-control rolling of the roller is avoided.

Description

technical field [0001] The invention belongs to the field of sporting goods, and in particular relates to abdominal fitness equipment. Background technique [0002] The more common structure of the existing abdominal health device is that the middle two rollers are attached, and then a handle tube runs through the two rollers. The user lies prone on the ground, grasps both ends of the handle tube with both hands, and pushes the abdomen health device forward or backward. Pull, the body cooperates with stretching or arching, and multiple reciprocating movements have an exercise effect. However, although the existing abdominal strengthening device adopts two rollers, the width of the wheels is relatively narrow, and beginners are not easy to grasp the center of gravity, and the strength is not well grasped, which is easy to cause muscle strain. The strength requirements are high, and it is difficult for beginners to complete many times. [0003] In view of the above problems,...
