[0002] A children's dining chair is a special chair designed for infants and young children, usually used to make children sit more safely and comfortably while eating.

[0003] In order to facilitate parents to care for and feed their children, rotatable dining chairs have appeared. The applicant has filed a patent with patent number CN201922497157.0. The application points out that "a conical groove is provided in the middle position of the upper end surface of the mounting seat, and the part of the conical rotating shaft located at the lower part of the square connecting plate is inserted into the conical groove. Such a structure realizes the free rotation of the conical rotating shaft; the plug-in hole cooperates with the elastic clamping device to realize the positioning of the conical rotating shaft. The clamping rod in the utility model is clamped into the plug-in hole in the square connecting plate by the action of the spring to realize positioning. When rotation is required, only the handle needs to be pulled open. The operation is convenient and simple. It can be completed by one parent. The operation is simple and reliable." This technology realizes rotation through the cooperation of a rotating seat and a conical rotating shaft, and the rotation can achieve stable rotation without any other assistance. The structure is simple and reliable.

[0004] The utility model realizes rotation by cooperating between a rotating seat and a conical rotating shaft. The handle needs to be pulled open during rotation, but it is not convenient to fix the chair after rotation, which may easily cause the dining chair to be in a rotatable state all the time, posing hidden risks.

[0027] Example 1

[0028] The utility model proposes a 360-degree dining chair, which combines practicality and comfort. Its structure mainly includes a seat, a dining board, a support seat, a connecting seat and a supporting leg. The dining board is installed above the seat, and the connecting seat is provided below. The connecting seat is installed on the supporting seat, and the supporting seat is connected to the supporting leg below. In order to increase the convenience of movement, a moving wheel is installed below the supporting leg, and a brake is equipped to ensure safety.

[0029] The connecting seat is composed of an upper fixed cover, a fixing part, an upper rotating part, a lower rotating part and a lower fixed cover. Each part works closely together to ensure the stability of the seat and the smoothness of rotation. The upper fixed cover is connected to the upper rotating part through a fixing part, and the upper rotating part is also connected to the lower rotating part through a fixing part, while the lower rotating part is connected to the lower fixed cover. A fixing column is set on the lower rotating part, and a fixing hole is opened on the fixing column. The fixing part is inserted into the hole when fixing, thereby locking the seat.

[0030] The upper rotating part is provided with a fixing groove, while the lower rotating part is provided with a fixing protrusion, which complement each other and provide more accurate positioning. In addition, a fixing column A is provided under the lower rotating part, and a fixing hole is provided on the fixing column A, which further enhances the stability of the seat.

[0031] The fixing parts include a push rod, a turntable gear and a positioning bolt. The push rod consists of a pressing part and a protruding part. The upper side of the pressing part is the protruding part, and the lower side is the gear structure. This design makes the operation easier. The turntable gear includes an insertion column, a chassis and a rotating tooth. The chassis is wrapped on the insertion column. The rotating tooth is partially installed on the chassis and partially installed on the insertion column. The rotating tooth part installed on the insertion column is an inclined structure, which undoubtedly increases the dynamic stability of the seat when rotating.

[0032] The upper and lower fixed covers are provided with gear parts at the mounting holes of the mounting fixings, including a mounting chassis and rotating teeth. The chassis is arranged on the upper and lower fixed covers, and a plurality of rotating teeth are arranged on the chassis, and gaps are arranged between the plurality of rotating teeth, which brings a smoother rotation experience to the user.

[0033] The utility model realizes rotation through the upper rotating member and the lower rotating member, and when fixing, the components on the upper fixed cover or the lower fixed cover are passed through the upper rotating member and the lower rotating member, so as to realize rotation and fixing at any angle. This design not only improves the flexibility of use, but also enhances the stability of fixing, bringing a more comfortable experience to users.

[0034] When in use, the user only needs to lightly press the top rod on the fixing part to separate the upper rotating part and the lower rotating part from the upper fixed cover and the lower fixed cover, then manually rotate the seat to the required position, and then press the top rod on the fixing part to pass the parts through the upper rotating part and the lower rotating part to complete the fixation.

[0035] In addition, the utility model also has safety performance. The brake design on the moving wheel can automatically lock or release when the user sits down or leaves the seat, preventing the user from falling due to accidental movement of the seat. At the same time, the rotation operation of the seat can also be achieved through an electronic control system, and the user can adjust the angle and position of the seat through the controller, which is more convenient and safer.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
