The material is generally high-quality engineering plastics, and the design is succinct, the appearance is pleasing to the eye, sturdy and durable, convenient to use for temper the proud flesh of each position of the equal body such as belly, waist buttock, arm. The required field is simple when exercising, so that the device is convenient to use at home.

The common use modes of the exercise wheel comprise the following modes:

1. standard kneeling posture: the knees are placed on the kneelers, the handles of the exercise wheels are tightly held by the two hands, the exercise wheels are pushed forwards until the body is horizontal to the ground, and then the kneelers are recovered and returned to the original position for repeated operation.

2. Standard standing posture: the two feet are closed and stand on the horizontal ground, the handles of the abdomen building wheels are tightly held by the two hands, the abdomen building wheels are pushed forwards until the body is horizontal to the ground, and then the abdomen building wheels are recovered and returned to the original position for repeated operation.

3. Practicing legs: sitting on the chair, putting two feet on the handle of the exercise wheel, pushing the exercise wheel with the feet, extending forwards, then recovering and returning to the original position, and repeating the operation.

4. Yoga-style training: sitting on the ground, the two feet are opened into a V shape, the abdomen building wheel handle is grasped, the body is extended forwards or rightwards to the maximum extent, and then the abdomen building wheel is recovered and returned to the original position for repeated operation.

5. Back type training: sitting on the ground, putting the abdomen building wheel at the back, grasping the abdomen building wheel handle with two hands to push the abdomen building device to extend the body backwards to the maximum extent, then recovering and returning to the original position, and repeating the operation.

6. Training light strength: facing the wall, lifting the exercise wheel to push the exercise wheel to the wall, extending upwards, then recovering and returning, and repeating the operation.

However, no matter which exercise method is adopted, there are exercisers with small strength that are difficult to use; and when the action is recovered, the recovery distance is easy to be larger, so that the problem of injury to the exerciser is easily caused.

Disclosure of Invention

The invention aims to provide a steel sheet spring body building wheel which has the characteristics of resilience and limiting effect.

The technical scheme adopted by the invention is as follows: steel sheet spring body-building wheel, including the center pin, steel sheet spring body-building wheel is still including fixed left bowl physique and the right bowl physique that form a hollow gyro wheel together, the central point of this left bowl physique puts the central point that all is equipped with the perforation with this right bowl physique, this center pin clearance fit wears to establish in 2 perforation, and this center pin can not remove about for this hollow gyro wheel, and, be fixed with the sleeve on the inner chamber right flank of this left bowl physique and/or on the inner chamber left flank of this right bowl physique, be equipped with a steel sheet spring in the sleeve, the one end of steel sheet spring is connected on this center pin, the other end is connected on corresponding telescopic inner chamber lateral wall.

The left end and the right end of the central shaft are both fixed with a handle sleeve, and the hollow roller is clamped in the middle by 2 handle sleeves.

Compared with the prior art, the invention has the advantages that: has the functions of springback and limiting. The steel sheet spring body building wheel is characterized in that a sleeve capable of rotating relative to the central shaft is fixed in the hollow roller, the steel sheet spring is arranged in the sleeve, and two ends of the steel sheet spring are respectively connected with the central shaft and the sleeve, so that once the hollow roller rotates, the steel sheet spring can be tightened to have certain resilience force, and even an exerciser with small strength can easily reset. Simultaneously, when the hollow gyro wheel of reverse rotation, the steel sheet spring can tend to become loose then its diameter becomes bigger more, and after the diameter reached certain degree, the steel sheet spring can receive the restriction of sleeve inner chamber lateral wall, makes the hollow gyro wheel can't continue reverse rotation, has formed certain spacing in other words, better protection the person taking exercise, make it be difficult for because of moving too big or be difficult for controlling and strain.

Detailed Description

Examples, see fig. 1-3: the steel plate spring body building wheel includes central shaft 10.

Further speaking:

the steel plate spring body building wheel also comprises a left bowl-shaped body 21 and a right bowl-shaped body 22 which are fixed together by buckling or screw connection and the like to form a hollow roller 20. The center of the left bowl-shaped body 21 and the center of the right bowl-shaped body 22 are both provided with through holes 23. The central shaft 10 is inserted into the 2 through holes 23 in a clearance fit manner. That is, the center shaft 10 and the hollow roller 20 have the same axis, and both left and right portions of the center shaft 10 extend to the outside of the hollow roller 20. The central shaft 10 is not movable left and right with respect to the hollow roller 20. For example, the central shaft 10 is provided with a plurality of steps for limiting. In this embodiment, a handle sleeve 50 is fixed to each of the left and right ends of the central shaft 10, and the diameters of the end surfaces of 2 handle sleeves 50 are larger than the inner diameter of the through hole 23 so that the 2 handle sleeves 50 clamp the hollow roller 20 therebetween.

More specifically:

a sleeve 30 is fixed on the right side surface of the inner cavity of the left bowl-shaped body 21 and/or the left side surface of the inner cavity of the right bowl-shaped body 22. The sleeve 30 preferably has a bottom and is fixed to the corresponding left or right bowl 21, 22 by means of screws. Alternatively, the sleeve 30 is substantially integral with the respective left or right bowl 21, 22. A steel spring 40 is disposed in the sleeve 30, the steel spring 40 is inevitably sleeved on the central shaft 10, and one end of the steel spring 40 is connected to the central shaft 10, and the other end is connected to the corresponding side wall of the inner cavity of the sleeve 30. Like this, when the exerciser both ends that hold this center pin 10 of both hands are bowing the appearance forward and are lying prone down, this hollow gyro wheel 20 rolls forward, and steel sheet spring 40 can be tightened up and then gathered sufficient potential energy, and the resilience force that this kind of potential energy formed is then favorable to the exerciser to retrieve the action that resets. However, when the hollow roller 20 is reversed to a sufficient extent during the recovery and return, the diameter of the steel plate spring 40 will become larger until the hollow roller 20 cannot rotate continuously after being limited enough by the side wall of the inner cavity of the sleeve 30, which is equivalent to forming a limit. That is, the hollow roller 20 does not excessively roll forward and excessively roll backward, greatly ensuring the safety of the exerciser.

Optimizing:

repeated verification of practical use can reasonably set the expansion length of the steel disc spring 40 according to the experimental result, and the movement stroke of the hollow roller 20 is 1300-1850 mm. Thus, it is possible to ensure that the moving distance of the hollow roller 20 is more scientific and the user is more comfortable and safe.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
