Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0029] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] like Figure 1-8 As shown, a safety abdominal muscle wheel includes a support mechanism, a movement restriction and a loss of control protection device;
[0031] The supporting mechanism includes a hard shell 10, a movable shaft 12 and a handle shaft 18. The handle shaft 18 is arranged in the middle of the hard shell 10 and is rotatably connected thereto. Both ends of the handle shaft 18 extend out of the two side surfaces of the hard shell 10. The movable shaft 12 is rotatably arranged inside the hard shell 10. The handle shaft 18 is provided with a movement limiting and loss of control protection device, and the movable shaft 12 is provided with a moving wheel 11. The movement limiting and loss of control protection device can limit the moving distance of the device each time and stop the device from moving when the device loses control.
[0032] The moving shafts 12 can be arranged in pairs or in a single arrangement, and the moving wheels 11 arranged on the moving shafts 12 can appear in pairs or in a single arrangement, and can be arranged at the side or in the middle. Being arranged at the side will increase the difficulty for the trainer, so that the trainer must control the strength to ensure balance;
[0033] In one embodiment, the movement limiting and out-of-control protection device includes a driving gear 13, a driven gear 14, a clamp hole 15, a base block 17, an arc block 19, a centrifugal block 20 and a reset spring 21. The clamp hole 15 is annularly arranged on the side wall of the hard shell 10 with the handle shaft 18 as the center, the base block 17 and the driven gear 14 are fixedly arranged on the handle shaft 18, the base block 17 is a circular structure, and an arc block 19 is fixedly arranged on the outer side of the arc, the radius of the base block 17 is smaller than the radius of the clamp hole 15, and the outer edge of the arc block 19 is larger than the radius of the clamp hole 15, the driven gear 14 is meshed with the driving gear 13 fixedly arranged on the moving shaft 12, and a clamp (not shown in the figure) is installed in the clamp hole 15. The outer edge of the base block 17 is provided with annular grooves, and a centrifugal block 20 is slidably arranged in the grooves. A reset spring 21 is fixedly arranged at the lower end of the centrifugal block 20, and the other end of the reset spring 21 is fixedly connected to the bottom wall of the groove. The maximum distance of the centrifugal block 20 when extended outward is greater than the distribution radius of the clamp hole 15. When in use, first insert the clamp into the appropriate hole position in the clamp hole 15. When the user pulls the device to move, the moving wheel 11 will drive the driving gear 13 to rotate, so that the driven gear 14 drives the coaxial base block 17 to rotate, so that the arc block 19 moves. When it moves to the position limited by the clamp, the arc block 19 will be blocked by the clamp, thereby stopping the movement. Since the pushing and pulling distances of each trainee are different, the different hole positions where the clamp is located can be flexibly adjusted to achieve different movement distances.
[0034] When the user is exhausted or loses control due to other circumstances, the device is often pushed out or pulled back quickly. At this time, the driving gear 13 will drive the driven gear 14 to rotate, causing the coaxial base block 17 to rotate quickly, so that the centrifugal block 20 is thrown out under the action of centrifugal force. Once thrown out, the centrifugal blocks 20 with a distribution radius larger than the clamp hole 15 are evenly distributed on the base block 17, so that the centrifugal blocks 20 immediately contact the clamp, thereby stopping the base block 17 from rotating, and then driving the driving gear 13 in the opposite direction through the driven gear 14 to stop the device from moving, thereby ensuring that the user will not lose balance.
[0035] In one embodiment, a through slot 22 is provided on the upper portion of the hard shell 10, and the driven gear 14 is provided in the through slot 22 and partially extends out; a scale is provided on the driven gear 14. The distance moved each time can be seen on the exposed portion of the driven gear 14, so as to serve as a mark to remind the user whether the distance of each movement is consistent and whether the action is standard or not.
[0036] In one embodiment, the clamp is a separately detachable pin.
[0037] In one embodiment, the clamp is a component fixedly disposed on the hard shell 10 corresponding to the clamp hole 15 and capable of switching between an extended state and a retracted state by pressing multiple times.
[0038] In one embodiment, a handle 16 is rotatably disposed on the protruding end of the handle shaft 18 .
[0039] In one embodiment, the moving wheel 11 is provided with anti-slip rubber.
[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
