[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-3 As shown,

[0020] A rotating seat base includes a chassis 1 and a rotating shaft 2 installed on the chassis 1, wherein the chassis 1 is provided with a connecting piece 3 for installing the rotating shaft 2, and the connecting piece 3 is provided with a slot 31 for inserting the rotating shaft 2, and the end of the rotating shaft 2 corresponding to the slot 31 is installed with a bearing 4, and the rotating shaft 2 is rotatably installed in the slot 31 through the bearing 4; the rotating shaft 2 is also provided with a thread 21, and the thread 21 is used for installation in conjunction with a seat body, and the rotating shaft 2 is also covered with a nut 5, which is connected to the thread 21 of the rotating shaft 2 and is used to support the limited seat body.

[0021] This solution can be matched through the thread 21 connection between the nut 5 and the rotating shaft 2. The support position of the seat body can be adjusted by rotating the nut 5 on the rotating shaft 2, so that the height can be adjusted to adapt to the play of children of different sizes, and can maintain a good adaptation state as the child grows. The setting of the slot 31 also facilitates the installation of the bearing 4 and the rotating shaft 2, making the rotation of the rotating shaft 2 more stable.

[0022] At the same time, in order to make the installation of the seat body more convenient and the support more stable, in an optional embodiment, a connecting plate 6 for cooperating with the seat body for installation is installed at the other end of the rotating shaft 2 corresponding to the chassis 1, and the connecting plate 6 is connected to the thread 21 of the rotating shaft 2, and the nut 5 abuts the connecting plate 6.

[0023] The connecting plate 6 and the rotating shaft 2 are installed in advance, and then the connecting plate 6 and the seat body are fixed with bolts. The connecting plate 6 can increase the support area of ​​the seat body, thereby distributing the pressure. Moreover, the connecting plate 6 is connected to the thread 21 of the rotating shaft 2 by thread 21, which can make the installation more convenient. The connecting plate 6 part can be made of metal material, which has higher strength, and the thread 21 between the rotating shaft 2 is more stable, and there will be no problem of thread slippage.

[0024] In addition, a protrusion 61 is provided at a position of the connection disk 6 corresponding to the rotating shaft 2 , and a channel 62 for inserting the rotating shaft 2 is provided along the axial direction of the protrusion 61 , and the channel 62 is connected to the thread 21 of the rotating shaft 2 .

[0025] The protrusion 61 on the connecting plate 6 can allow the rotating shaft 2 to have a larger movable space, so that the height adjustment range of the seat body is larger and the practicality is better.

[0026] In order to facilitate the installation between the bearing 4 and the rotating shaft 2 , the position where the rotating shaft 2 and the bearing 4 are installed is smooth and has an interference fit with the inner ring of the bearing 4 .

[0027] The interference fit between the smooth surface and the inner ring of the bearing 4 can make the installation of the shaft 2 more convenient. In addition, the smooth surface of the bearing 4 can continue to be inserted into the slot 31 to achieve positioning and better cooperation.

[0028] In order to further enhance the fun, the chassis 1 is provided with an inclined support rod 7, and the connecting member 3 is located on the support rod 7, and the connecting member 3 is arranged upward perpendicular to the support rod 7. The inclined support rod 7 cooperates with the connecting member 3 to allow the rotating shaft 2 to rotate obliquely, so that the seat body rotates obliquely, and the seat body produces a swaying effect on the child during the rotation process, thereby exercising the gripping strength of the hands.

[0029] In a further configuration, in order to facilitate the rotation of the nut 5 and the locking of the connecting plate 6 , a handle 51 is provided on the side of the nut 5 .

[0030] The handle 51 enables the user to apply force more conveniently without the need for other tools.

[0031] Based on the above structure, the steps for adjusting the seat body are as follows: first, press the seat body by hand to prevent it from rotating (at this time, since the nut 5 and the connecting plate 6 are in a tight state, they can rotate relative to each other), and rotate the nut 5 to move the nut 5 downward, so that the nut 5 and the connecting plate 6 are separated. At this time, without the tightness of the nut 5, the thread 21 between the connecting plate 6 and the rotating shaft 2 can be easily rotated, and the rotating shaft 2 is pressed by hand to prevent it from rotating, and the connecting plate 6 is rotated to allow the connecting plate 6 to move upward or downward. Finally, the nut 5 is rotated to re-tighten the protrusion 61 on the connecting plate 6, thereby locking the connecting plate 6.

[0032] The above describes a swivel seat base, which is assembled with a seat body to form a seat.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
