They are mainly used for physical therapy to train people's motor nerves and balance. They are suitable for all people to practice, including those in need of rehabilitation treatment. They have good fitness effects, especially for the exercise of the spine and pelvis. Yoga balls have good loss recovery and rehabilitation functions and remarkable curative effects on lumbar and back diseases. Yoga balls are relatively safe during exercise and are not easily damaged. Yoga balls can improve people's strength, posture, flexibility, balance and cardiopulmonary function.

[0006] Preferably, the blocking structure includes a spring, a first annular baffle, a second annular baffle, a circular baffle, a first rubber sealing ring and a second rubber sealing ring. The first annular baffle is provided on the inner wall of the tear-resistant layer, the first rubber sealing ring is provided on the first annular baffle, the first annular baffle is communicated with the second installation hole, the second annular baffle is also provided on the inner wall of the tear-resistant layer, the second rubber sealing ring is provided on the second annular baffle, one end of the spring is connected to the inner wall of the tear-resistant layer, the other end of the spring is connected to the circular baffle, the spring is located between the first annular baffle and the second annular baffle, and the first rubber sealing ring and the second rubber sealing ring are in contact with the circular baffle.

[0007] Preferably, the plug is provided with anti-slip lines and is made of plastic material.

[0008] Preferably, anti-slip strips are evenly arranged on the outer wall of the waterproof layer.

[0009] Preferably, the surfaces of the waterproof layer and the anti-slip strip are both provided with silver ion coating.

[0010] Preferably, the second mounting hole may be threadedly connected with an air pumping tube, and the length of the external thread of the air pumping tube is greater than the length of the external thread of the plug.

[0011] The beneficial effects of the utility model are: one end of a spring is connected to the inner wall of the tear-resistant layer, the other end of the spring is connected to a circular baffle, the spring is located between the first annular baffle and the second annular baffle, the first rubber sealing ring and the second rubber sealing ring are in contact with the circular baffle, when the air tube is screwed out, the circular baffle contacts the first rubber sealing ring and the second rubber sealing ring under the action of the spring elastic force, the air in the tear-resistant layer will not leak out temporarily, and then when the plug is tightened, the internal gas can achieve the expected inflation effect.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings.

[0021] As Figures 1-6 shown, a yoga ball includes a waterproof layer 1, a tear-resistant layer 3, a plug 6 and a blocking structure.

[0022] Specifically, the inner wall of the waterproof layer 1 is connected to the tear-resistant layer 3. The waterproof layer 1 is provided with a first mounting hole 4, which facilitates the installation and removal of the plug 6. The tear-resistant layer 3 is provided with a second mounting hole 5, and an internal thread is provided in the second mounting hole 5. The second mounting hole 5 is threadedly connected to the plug 6, and an external thread is provided on the plug 6. The threaded structure can fasten the plug 6 on the second mounting hole 5, improving the stability. The blocking structure is installed on the inner wall of the tear-resistant layer 3 to temporarily prevent air leakage.

[0023] Specifically, the blocking structure includes a spring 8, a first annular baffle 9, a second annular baffle 10, a circular baffle 11, a first rubber sealing ring 7 and a second rubber sealing ring 12. A first annular baffle 9 is provided on the inner wall of the tear-resistant layer 3, and a first rubber sealing ring 7 is provided on the first annular baffle 9. The first annular baffle 9 communicates with the second mounting hole 5. There is also a second annular baffle 10 provided on the inner wall of the tear-resistant layer 3, and a second rubber sealing ring 12 is provided on the second annular baffle 10. One end of a spring 8 is connected to the inner wall of the tear-resistant layer 3, and the other end of the spring 8 is connected to a circular baffle 11. The spring 8 is located between the first annular baffle 9 and the second annular baffle 10. The first rubber sealing ring 7 and the second rubber sealing ring 12 are in contact with the circular baffle 11, which can effectively prevent gas from leaking out.

[0024] Specifically, the plug 6 is provided with anti-slip grooves 13, which can increase the friction and facilitate the screwing out of the plug 6. The plug 6 is made of plastic material; anti-slip strips 2 are evenly arranged on the outer wall of the waterproof layer 1, and the anti-slip strips 2 can facilitate the taking and placing of this device; silver ion coatings are provided on the surfaces of the waterproof layer 1 and the anti-slip strips 2, and the silver ion coatings have good antibacterial effects; the second mounting hole 5 can be threadedly connected with an air pump 14, and the length of the external thread of the air pump 14 is greater than the length of the external thread of the plug 6. The air pump 14 can drive the circular baffle 11 away from the first rubber seal ring 7 and the second rubber seal ring 12, facilitating inflation and deflation.

[0025] Working principle: When it is necessary to inflate this device, first screw out the plug 6, then screw the air pump 14 into the second mounting hole 5. The air pump 14 pushes out the circular baffle 11. At this time, the spring 8 deforms and is in a stretched state. The circular baffle 11 moves away from the first rubber seal ring 7 and the second rubber seal ring 12. Then connect the other end of the air pump 14 to an air pump, and then carry out the inflation work. When this device is fully inflated, quickly screw out the air pump 14. At this time, under the elastic force of the spring 8, the circular baffle 11 contacts the first rubber seal ring 7 and the second rubber seal ring 12, and the air in the tear-resistant layer 3 will not leak out temporarily. Then tighten the plug 6 to be able to use this device normally;

[0026] When it is necessary to deflate this device, screw out the plug 6 and then screw in the air pump 14, and wait for the air to be released.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
