Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a pneumatic tire type abdominal wheel, including a grip rod 1 and a braking device. Two hubs 2 are rotatably sleeved on the surface of the grip rod 1. Pneumatic tires 3 are installed on the surfaces of the two hubs 2. Rubber grip sleeves 4 are fixedly sleeved at both the left and right ends of the grip rod 1. Grooves 5 are arranged at equal intervals in a circular shape on the surfaces of the two rubber grip sleeves 4.

[0025] The user holds two rubber grips 4 with both hands, and the user can increase the contact area with the rubber grips 4 by squeezing the inner wall of the groove 5 with the hands, thereby increasing the friction between the hands and the rubber grips 4, ensuring the stability of the user's grip on the grip rod 1. Then, the user can push the grip rod 1 forward and drive the two inflatable tires 3 to roll on the ground. Moreover, when the two inflatable tires 3 contact the ground, it is a flexible contact with strong shock absorption ability, which can reduce the damage to the user's wrist and shoulder joints.

[0026] The braking device includes two mounting plates 6, two brake pads 7, two bumps 9, a semi-circular slider 11, a brake push block 12, a spring 13, and a connecting block 14. The two mounting plates 6 are both fixedly connected to the surface of the grip rod 1. The two brake pads 7 are respectively slidably mounted inside the two mounting plates 6. Braking slots 8 are formed on the surfaces of the two brake pads 7. The surface of the inflatable tire 3 is in contact with the inner wall of the braking slot 8. The two bumps 9 are respectively fixedly connected to the surfaces of the two mounting plates 6. Semi-circular chutes 10 are formed inside the two bumps 9. The semi-circular slider 11 is slidably connected inside the semi-circular chute 10. The brake push block 12 is fixedly connected to the surface of the semi-circular slider 11. The upper end of the spring 13 is fixedly connected to the bottom of the semi-circular slider 11, and the lower end of the spring 13 is fixedly connected to the bottom wall of the semi-circular chute 10. The connecting block 14 is fixedly connected to the surface of the semi-circular slider 11. One end of the connecting block 14 away from the semi-circular slider 11 is fixedly connected to the surface of the brake pad 7. The same structure is provided inside the two bumps 9.

[0027] When the user suddenly finds that they can't hold on during fitness, the user can move the brake push block 12 downward with the thumb. When the brake push block 12 slides downward, it can drive the semi-circular slider 11 to slide downward and compress the spring 13. The spring 13 gives an upward elastic force to the semi-circular slider 11. When the semi-circular slider 11 slides downward, it can drive the connecting block 14 to slide downward. The downward sliding of the connecting block 14 finally drives the brake pad 7 to slide downward and press on the surface of the inflatable tire 3 through the braking slot 8 for braking. Moreover, this abdominal wheel has a double-wheel structure. When the two inflatable tires 3 brake on the ground, the user can be supported by the two inflatable tires 3 on the ground, and the phenomenon of the user tilting will not occur. Therefore, when the user suddenly can't hold on during fitness, this abdominal wheel can be braked, thereby avoiding the user hitting the ground and improving the safety of the user's fitness.

[0028] Working principle: For this inflatable tire abdominal wheel, the user holds two rubber grips 4 with both hands. The user can then push the grip rod 1 forward and drive the two inflatable tires 3 to roll on the ground. Moreover, when the two inflatable tires 3 contact the ground, it is a flexible contact, which can reduce the damage to the user's wrist and shoulder joints. When the user suddenly finds that they can't hold on during fitness, the user can move the brake push block 12 downward with the thumb. The downward sliding of the brake push block 12 can drive the semi-circular slider 11 to slide downward and compress the spring 13. The downward sliding of the semi-circular slider 11 can drive the connecting block 14 to slide downward. The downward sliding of the connecting block 14 ultimately drives the brake pad 7 to slide downward and press on the surface of the inflatable tire 3 through the brake slot 8 for braking. And this abdominal wheel has a double-wheel structure. When the two inflatable tires 3 brake on the ground, the user can support on the ground through the two inflatable tires 3, preventing the user from tilting, thereby avoiding the user hitting the ground and improving the safety of the user's fitness.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
