The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and apparent to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein and can be practiced without these specific details.
[0037] It will be understood that, herein, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another entity or operation, and are not intended to express or imply any actual relationship or order between these entities or operations.
[0038] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0039] Reference Figs. 1 to 6 As shown, a children's sports and physical training equipment includes a bracket 1, wherein the bracket 1 is provided with a roller 2 for children to perform running training, and the roller 2 is rotatably connected to the bracket 1;
[0040] The bracket 1 is provided with a support shaft 11, and the drum 2 is rotatably connected to the bracket 1 via the support shaft 11;
[0041] The support shaft 11 is further provided with a counterweight cylinder 3, and the counterweight cylinder 3 is rotatably connected to the support shaft 11;
[0042] The centrifugal transmission assembly is arranged between the roller 2 and the counterweight cylinder 3, and comprises a slewing disc 111 rotatably connected to the support shaft 11, the roller 2 drives the slewing disc 111 to rotate, the slewing disc 111 is provided with a friction plate 112, the friction plate 112 is arranged on the slewing disc 111 in the diametric direction of the slewing disc 111, and the slewing disc 111 drives the counterweight cylinder 3 by the friction between the friction plate 112 and the counterweight cylinder 3.
[0043] When the rotation speed of the roller 2 is greater than or equal to a set rotation speed, the friction plate 112 is in contact with the counterweight cylinder 3 under the action of centrifugal force, and when the rotation speed of the roller 2 is less than the set rotation speed, the friction plate 112 is automatically separated from the counterweight cylinder 3.
[0044] Generally, the roller 2 has a large diameter, so that children are easier to operate when using. When the roller 2 has a large diameter, the roller 2 has a large inertial force during rotation, and when the rotation speed of the roller 2 is too fast, the inertial force of the roller 2 is greater, and children can make the roller 2 have a high rotation speed even if a small force is applied. However, the reaction speed of children is limited, and when the rotation speed of the roller 2 is too fast, children may not react in time and fall down, so it is necessary to avoid the rotation speed of the roller 2 being too fast.
[0045] By arranging the counterweight cylinder 3 and the centrifugal transmission assembly, the roller 2 drives the slewing disc 111 to rotate during rotation, the friction plate 112 does not contact the roller 2 when the slewing disc 111 rotates at a normal speed, and the roller 2 does not drive the counterweight cylinder 3 to rotate at this time. When the rotation speed of the roller 2 is too fast, the friction plate 112 moves to the counterweight cylinder 3 under the action of centrifugal force, and when the friction plate 112 contacts the counterweight cylinder 3, the roller 2 drives the counterweight cylinder 3 to rotate under the action of friction, and since the counterweight cylinder 3 has a certain weight, the counterweight cylinder 3 effectively prevents the rotation speed of the roller 2 from being too fast.
[0046] At the same time, since there is a certain slip between the friction plate 112 and the counterweight cylinder 3, that is, the friction plate 112 slips relative to the counterweight cylinder 3, so that the friction plate 112 does not immediately drive the counterweight cylinder 3 to rotate when the friction plate 112 contacts the counterweight cylinder 3, and there is a certain buffer, so that the rotation speed of the roller 2 does not suddenly decrease, and the safety of the children's physical fitness training equipment is improved.
[0047] Reference Figs. 1 to 6As shown, in some embodiments, the friction plate 112 is provided with a sliding rod 1121, the rotating disc 111 is provided with a sliding hole matched with the sliding rod 1121, and an elastic member 1122 is arranged between the sliding rod 1121 and the rotating disc 111 to push the sliding rod 1121 to make the friction plate 112 disengage from the counterweight cylinder 3.

[0050] The friction plate 112 is at least three, at least three friction plates 112 are uniformly distributed along the circumferential direction of the rotating disc 111, each friction plate 112 is slidably connected to the rotating disc 111 through an independent sliding rod 1121, and each sliding rod 1121 is provided with an independent elastic member 1122.
[0051] The more the number of friction plates 112 is, the larger the total contact area between the friction plates 112 and the cylinder 2 is, and the easier the cylinder 2 drives the counterweight cylinder 3 to rotate.
[0052] Referring to Figs. 1 to 6 As shown, in some embodiments, the cylinder 2 drives the rotating disc 111 through a gear transmission mechanism, and the rotating speed of the rotating disc 111 is greater than that of the cylinder 2.
[0053] Generally, the rotating speed of the cylinder 2 may not be fast enough to displace the friction plate 112, therefore, by arranging the gear transmission mechanism, the rotating disc 111 can have a higher rotating speed, and the friction plate 112 is easy to displace under the action of centrifugal force and contact the counterweight cylinder 3.
[0054] In some embodiments, the gear transmission mechanism comprises a gear ring 21 arranged on the cylinder 2, further comprises an intermediate gear 13 arranged on the support shaft 11, the intermediate gear 13 is installed on the support shaft 11 through a support plate 131, the support plate 131 is in an integral structure with the support shaft 11, the intermediate gear 13 is rotatably connected to the support plate 131, the gear ring 21 is engaged with the intermediate gear 13, and the rotating disc 111 is provided with a driven gear 1112 engaged with the intermediate gear 13.

The counterweight cylinder 3 can be arranged in the roller 2, and when the counterweight is arranged in the roller 2, the support rib 23 is detachably connected to the roller 2, so that the counterweight cylinder 3 is easy to assemble.
[0059] In some embodiments, the support frame 1 is provided with a motion platform 14, the motion platform 14 is provided with a groove, the groove penetrates through the motion platform 14, a part of the roller 2 protrudes out of the motion platform 14 through the groove, the support frame 1 is further provided with a staircase 15 facilitating children to enter the motion platform 14, and the motion platform 14 and the staircase 15 are both provided with a fence 16, and the fence 16 is sleeved with a sponge layer.
[0060] The sponge layer can also be attached on the motion platform 14.
[0061] In some embodiments, children can hold the fence 16 to move, or a separate handrail can also be arranged on the motion platform 14.
[0062] The support shaft 11 is fixed to a rack, and the support shaft 11 does not rotate.
