[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5 One embodiment provided by this utility model:

[0035] An ab roller with a rebound function includes a wheel body 1. An anti-slip pad 6 is fixedly connected to the middle of the outer wall of the wheel body 1. Multiple guide blocks 7 are fixedly connected to the outer wall of the anti-slip pad 6, so that the user can clearly understand the direction of the ab roller and reduce the possibility of the ab roller slipping. Limiting grooves 2 are opened on both sides of the outer wall of the wheel body 1. A connecting block 8 is fixedly connected to the center of the inner wall of one side of the limiting groove 2. A rotating ring 11 is fixedly connected to the outer wall of the connecting block 8. A housing 4 is rotatably connected to the outer wall of the rotating ring 11 away from the wheel body 1. A rebound mechanism 3 is provided on the inner wall of the housing 4. The rebound mechanism 3 includes a positioning rod 301, a positioning groove 302 and an elastic roll 303. A positioning ring 304 and a positioning block 305 are fixedly connected to both ends of the outer wall of the elastic roll 303, respectively. A grip mechanism 5 is provided on the outer wall of the housing 4. The grip mechanism 5 includes a connecting seat 501 and a handle 502.

[0036] Compared to most traditional ab rollers, this ab roller is equipped with a rebound mechanism 3. When the wheel 1 is pushed to move, the elastic coil 303 will contract. When it is necessary to pull back, the elastic coil 303 will release its elasticity to reset, thereby applying a rotational force to the wheel 1. This helps the user to perform the pull-back operation, reducing the risk of falls or injuries that beginners may experience due to unstable control when pulling back. This improves both the ease of operation and the safety of use of this ab roller.

[0037] Multiple limiting slots 9 are provided on one side of the outer wall of the connecting block 8, and multiple limiting blocks 12 are fixedly connected to one side of the inner wall of the rotating ring 11, allowing the user to disassemble or install the outer shell 4 on the wheel body 1. Locking bolts 10 are threaded onto the inner wall of the limiting slots 9 near the connecting block 8, allowing the user to install or disassemble the rotating ring 11 and the connecting block 8 using the locking bolts 10. A positioning rod 301 is fixedly connected to one side of the inner wall of the outer shell 4, and a positioning groove 302 is provided on one side of the outer wall of the rotating ring 11, allowing the user to disassemble and replace the elastic roll 303, so that it can be replaced with a new one after prolonged use, reducing the impact on the abdominal exercise wheel. The positioning ring 302... The positioning block 305 engages with the positioning groove 302, and the positioning rod 301 engages with the positioning block 305, so that the elastic roll 303 can be positioned between the outer shell 4 and the rotating ring 11. Thus, the rotation of the rotating ring 11 will control the elastic roll 303 to retract. The connecting seat 501 is fixedly connected to the middle of the outer wall of the outer shell 4, and the handle 502 is fixedly connected to the center of the outer wall of the connecting seat 501, so that the user can easily disassemble or install the handle mechanism 5 on the outer shell 4. Multiple connecting bolts 504 are provided around the outer wall of the connecting seat 501, and a soft pad 503 is fixedly connected to the outer wall of the handle 502, so that the user can disassemble or install the connecting seat 501 by rotating the connecting bolts 504.

[0038] Working principle: First, the user grips the handle 502 with both hands and pushes the wheel 1 along the guide block 7. When the wheel 1 rotates, the outer shell 4 remains stationary with the position of the handle 502, while the rotating ring 11 rotates with the wheel 1. The rotation of the rotating ring 11 while the outer shell 4 remains stationary causes the elastic coil 303 to contract towards the rotating ring 11, thus accumulating elasticity. When the user moves to a certain position and wants to pull back, the elastic coil 303 will release its elastic force to assist the wheel 1 in rotating in the opposite direction, reducing the force required for the user to pull back, thereby reducing the possibility of falls or injuries caused by unstable control when beginners pull back.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
