Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically an ab wheel with an emergency braking mechanism. Background Technology

[0002] An ab wheel is a commonly used small fitness equipment that can focus on exercising the rectus abdominis muscle, the main part of the abdominal muscles, also known as the "six-pack". It usually consists of a wheel, a support frame, and handles on both sides. Users can use their core strength to push the wheel forward and back by holding the handles with both hands to complete the exercise.

[0003] Because current ab wheels rely solely on the user's own strength to control the wheel and lack an active braking protection mechanism, beginners or those with insufficient strength may experience situations where the ab wheel cannot stop in time, such as when the wheel rolls back rapidly or when it tilts due to wear on the outer wall of the wheel or uneven training ground. This can easily lead to lower back strain or loss of balance and falls, resulting in insufficient safety when using the device. Therefore, we propose a new type of ab wheel with an emergency braking mechanism to solve the aforementioned defects. Utility Model Content

[0004] The purpose of this invention is to provide an ab wheel with an emergency braking mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ab wheel with an emergency braking mechanism, comprising a support frame and further comprising... A horizontal bubble is embedded in one side of the support frame. The front wheel body and the rear wheel body are evenly and movably connected to both sides of the bottom of the support frame. Both the front wheel body and the rear wheel body are fitted with outer anti-slip wheel sleeves. The housing is fixed at the middle position of the support frame, and a circuit board and a rechargeable lithium battery are installed inside the housing in sequence. A grip handle is fixed to the top of one side of the support frame. Both ends of the grip handle are equipped with rubber anti-slip sleeves. A button switch box is connected to the outside of the housing via wires. The button switch box is equipped with an arc-shaped sleeve that engages with the rubber anti-slip sleeves. A hydraulic telescopic cylinder is fixed at the middle position of the bottom of the housing. The output end of the hydraulic telescopic cylinder is connected to a brake suction cup. Negative pressure suction holes are evenly arranged at the bottom of the brake suction cup, and a pressure relief valve is installed at the top of the brake suction cup.

[0006] Furthermore, both the front wheel body and the rear wheel body are provided with two.

[0007] Furthermore, the inner wall of the outer anti-slip wheel sleeve is uniformly fixed with positioning inserts arranged at equal angles, and both the front wheel body and the rear wheel body are provided with positioning slots that match the positioning inserts.

[0008] Furthermore, both ends of the front wheel body and the rear wheel body are fixed with a first mounting side plate.

[0009] Furthermore, the bottom of the support frame is provided with a turntable that matches the front wheel body and the rear wheel body. The turntable and the edge of the first mounting side plate are both provided with screw holes, and screws are connected inside the screw holes.

[0010] Furthermore, a connecting bearing is provided between the turntable and the support frame.

[0011] Furthermore, the top of the support frame is evenly provided with three reserved mobile phone slots near the handle, making it convenient for users to attach their mobile phones to the device and play fitness videos to accompany training. The three reserved mobile phone slots in different positions also make it easier for users to adjust the distance between the mobile phone and the handle, thus increasing flexibility.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This ab wheel with an emergency braking mechanism optimizes its structure by incorporating a hydraulic telescopic cylinder. Firstly, the four-wheel design (two front wheels and two rear wheels) at the bottom provides greater stability and load-bearing capacity compared to a single-wheel design. Furthermore, a spirit level allows users to easily monitor the levelness of the operating surface and check for wear on the wheels, preventing tipping due to unevenness and enhancing safety during ab exercises. Secondly, users can easily install the push-button switch box using the locking mechanism between the curved sleeve and the rubber anti-slip sleeve. The handle is positioned at an appropriate location for pressing the button switch box in case of loss of balance. This activates the hydraulic telescopic cylinder, causing the brake suction cup at its output end to press against the training ground for emergency braking. Simultaneously, as the brake suction cup presses against the training ground, the negative pressure suction holes at the bottom of the brake suction cup are compressed to expel internal gas and create negative pressure, thus achieving adhesion and fixation between the brake suction cup and the training ground. This dual-fixation structure enhances the emergency braking effect and prevents poor braking performance due to excessive impact force, further improving the safety performance of the device. Subsequently, the user only needs to open the pressure relief valve to allow ambient gas to fill the brake suction cup, thereby releasing the adhesion and fixation effect and allowing the device to be removed.

[0018] Please see Figure 1-4 One embodiment of this utility model provides: an ab wheel with an emergency braking mechanism, including a support frame 6, and further comprising... A horizontal bubble 5 is embedded on one side of a support frame 6. The front wheel body 7 and the rear wheel body 12 are evenly and movably connected to the two sides of the bottom of the support frame 6. Both the front wheel body 7 and the rear wheel body 12 are fitted with outer anti-slip wheel sleeves 11. Both the front wheel assembly 7 and the rear wheel assembly 12 are provided with two; The inner sidewall of the outer anti-slip wheel sleeve 11 is evenly fixed with positioning inserts 16 arranged at equal angles, and the front wheel body 7 and the rear wheel body 12 are both provided with positioning slots 15 that match the positioning inserts 16. Both ends of the front wheel body 7 and the rear wheel body 12 are fixed with the first mounting side plate 22; The bottom of the support frame 6 is provided with a turntable 20 that matches the front wheel body 7 and the rear wheel body 12. The turntable 20 and the edge of the first mounting side plate 22 are evenly provided with screw holes, and screws are connected inside the screw holes. A connecting bearing 21 is provided between the turntable 20 and the support frame 6; When in use, the device features a four-wheeled motion structure consisting of two front wheels 7 and two rear wheels 12 at the bottom, which is more stable and has a better load-bearing capacity than a single-wheel design. On the other hand, the level bubble 5 allows users to easily observe whether the operating ground is level and whether the balance of the device is affected by wear of the four wheel structures. This can avoid the problem of tipping over due to tilting when the device is not level, thus improving the safety of abdominal training. The housing 8 is fixed at the middle position of the support frame 6. The circuit board 18 and the rechargeable lithium battery 19 are installed inside the housing 8 in sequence. A grip handle 2 is fixed to the top of one side of the support frame 6. Both ends of the grip handle 2 are provided with rubber anti-slip sleeves 1. The outside of the housing 8 is connected to a button switch box 3 through a wire. The button switch box 3 is provided with an arc-shaped sleeve 4 that engages with the rubber anti-slip sleeve 1. A hydraulic telescopic cylinder 9 is fixed at the middle position of the bottom of the housing 8. The output end of the hydraulic telescopic cylinder 9 is connected to a brake suction cup 14. Negative pressure suction holes 13 are evenly arranged at the bottom of the brake suction cup 14. A pressure relief valve 17 is installed at the top of the brake suction cup 14. In use, the user can use the locking effect between the arc-shaped sleeve 4 and the rubber anti-slip sleeve 1 to install the button switch box 3 in a suitable position on the handle 2, so that when the body loses balance, the button switch box 3 can be pressed to activate the hydraulic telescopic cylinder 9, so that the brake suction cup 14 at its output end can press against the training ground for emergency braking. At the same time, when the brake suction cup 14 presses against the training ground, the negative pressure suction holes 13 arranged at the bottom of the brake suction cup 14 will be compressed to expel the internal gas and bring in negative pressure, so as to achieve the suction and fixation between the brake suction cup 14 and the training ground. In this way, the emergency braking effect is improved through the double fixation structure, avoiding the problem of poor braking effect caused by excessive impact force, and further improving the safety performance of the device. Afterwards, the user only needs to open the pressure relief valve 17 to let the external ambient gas fill into the brake suction cup 14 to release the suction and fixation effect, so as to remove the device. The top of the support frame 6 is evenly provided with three reserved mobile phone slots 10 near the handle 2, making it convenient for users to insert mobile phones into the device and play fitness videos to accompany training. The three reserved mobile phone slots 10 in different positions also make it easier for users to adjust the distance between the mobile phone and the handle 2, making it more flexible.

[0019] The working principle of this utility model is as follows: First, by setting a four-wheel motion structure consisting of two front wheels 7 and two rear wheels 12 at the bottom of the device, it is more stable and has a better load-bearing capacity compared to a single-wheel design. On the other hand, the level bubble 5 allows the user to easily observe whether the operating ground is level and whether the balance of the device is affected by wear of the four wheel structures. This can avoid the problem of tipping over due to insufficient levelness during operation, thus improving the safety of abdominal training. In specific operation, the user can use the locking effect between the arc-shaped sleeve 4 and the rubber anti-slip sleeve 1 to install the button switch box 3 in a suitable position on the handle 2. This makes it convenient to press the button switch box 3 when the body loses balance, activating the hydraulic telescopic cylinder 9, which causes the brake suction cup 14 at its output end to press against the training ground for emergency braking. At the same time, when the brake suction cup 14 presses against the training ground, the negative pressure suction holes 13 arranged at the bottom of the brake suction cup 14 will be compressed accordingly. By venting the internal gas and creating negative pressure, the brake suction cup 14 is adhered and fixed to the training ground. This double-fixation structure improves the emergency braking effect and avoids the problem of poor braking performance caused by excessive impact force, further enhancing the safety performance of the device. Subsequently, the user only needs to open the pressure relief valve 17 to allow ambient gas to fill the brake suction cup 14, thereby releasing the adhesion and fixing effect and allowing the device to be removed. In addition, the wheel structure will wear down over time, resulting in insufficient surface levelness and poor anti-slip properties. At this time, the user can remove the front wheel 7 and the rear wheel 12 through the mounting structure formed by screws between the turntable 20 and the first mounting side plate 22. Then, through the insertion action formed by the positioning slot 15 and the positioning insert 16, the outer anti-slip wheel sleeve 11 on the outer wall of the front wheel 7 and the rear wheel 12 can be replaced. By replacing the locally worn structure, the overall service life of the device is extended, resources are saved, and it is easy to promote.
