[0002] Children's dining chairs are widely used in daily life. Many families and restaurants have children's dining chairs for children to use. Children's dining chairs will not only help babies develop the habit of eating in dining chairs, avoiding the trouble of parents chasing after their babies to feed them, but also can exercise the coordination ability of babies' hands, eyes and brains. At the same time, it also has a great impact on the baby's sitting posture and physical development.

[0003] In order to facilitate users, the applicant has proposed a folding structure, which is convenient for users to fold and store the dining car. Patent No. CN201922497157.0 proposes a 360-degree rotating dining chair, which points out that an elastic clamping device is provided on the mounting seat, and the elastic clamping device is connected with the 360-degree rotating device to realize the positioning of the 360-degree rotating device. The elastic clamping device includes a clamping channel arranged on the side of the mounting seat, and the clamping channel runs through the mounting seat; a clamping slide rod is slidably connected in the clamping channel, and a rear baffle is fixedly installed in the rear part of the clamping channel; the clamping slide rod runs through the rear baffle, and a front baffle is fixedly installed in the front part of the clamping slide rod; a spring is sleeved on the clamping slide rod, one end of the spring is fixed on the rear baffle, and the other end of the spring is fixed on the front baffle; a clamping rod corresponding to the plug-in hole is provided at the inner end of the clamping slide rod, and the clamping rod is inserted into the plug-in hole to realize the positioning of the conical rotating axis; a handle is fixedly connected to the outer end of the clamping slide rod. The utility model realizes folding through the cooperation of the rotating shaft and the clamping shaft of the fixed rotating shaft. The rotating shaft rotates to open the front and rear legs, the footrest bracket and the dining board, and the seat is fixed as a whole through the clamping of the clamping shaft. When it needs to be stored and folded, it only needs to open the clamping shaft and the rotating shaft rotates to realize storage. The operation is convenient and reliable, and the practicability is strong.

[0004] The folding structure proposed in the application is relatively complex. Both the front and rear legs are equipped with their own shafts, which takes up a large space. If one of the shafts fails, the entire device cannot be folded for use. The patent proposes a snap-on shaft design to achieve folding and fixation, but during use, if the user does not operate properly or there are product quality issues, it may cause the folding to be unstable and even cause accidental injuries.

[0031] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0032] Example 1

[0033] The utility model is a 360-degree rotating dining chair folding structure, and its design features include front legs, rear legs, a first rotating shaft, a second rotating shaft, a rotating shaft seat and a fixing member. The front legs are installed on both sides of the first rotating shaft, and the second rotating shaft is cleverly mounted on the first rotating shaft, and the second rotating shaft is fixedly connected to the rear legs. The rotating shaft seat is located on the upper side of the first rotating shaft and the second rotating shaft, and connecting rods are provided at both ends, one end of which is inserted into the fixing hole of the second rotating shaft, and the other end is inserted into the rotating shaft seat. A fixing member is installed on one side of the rotating shaft seat, which passes through the rotating shaft seat and is connected to the first rotating shaft.

[0034] An inner structure is arranged inside the rotating shaft seat, and the inner structure is mounted on the upper sides of the first rotating shaft and the second rotating shaft. The inner structure includes fixed protrusions and grooves. The fixed protrusions and grooves of the inner structure correspond to the fixed protrusions and grooves of the second rotating shaft.

[0035] After the fixing member is fully inserted, the first rotating shaft is in fixed contact with the fixing member, the first rotating shaft is in a stuck position, and the second rotating shaft cannot rotate. When the fixing member and the first rotating shaft are in a disengaged state, the first rotating shaft is not stuck, and the second rotating shaft can rotate.

[0036] The utility model improves the original folding structure, making the improved folding structure more compact. When in use, it is only necessary to pull out the fixing part and change the position of the fixing part and the first rotating shaft to easily unfold or fold it. The operation is simple and convenient, avoiding dangerous accidents caused by mistakes. The design of this dining chair not only reflects the in-depth consideration of user needs, but also shows the designer's pursuit of safety and convenience.

[0037] Example 2

[0038] When the utility model is not in use and needs to be folded, the fixing part is pulled out from the first rotating shaft, and when the fixing part and the first rotating shaft are in a disengaged state, the first rotating shaft is not stuck, and the second rotating shaft can rotate freely. The first rotating shaft drives the front legs to move, and the second rotating shaft drives the rear legs to move, and the front legs and the rear legs are rotated at the same time to achieve the purpose of folding the vehicle.

[0039] In actual application, this design makes the product more efficient when folding. Users only need to pull the fixings to quickly fold the device, saving a lot of valuable time. At the same time, since the first and second rotating shafts are movable structures, the second rotating shaft can rotate freely when the first rotating shaft is not stuck, making the entire folding process smoother and further improving the user experience.

[0040] The utility model also has excellent adaptability. Whether it is outdoor adventure, travel vacation, or daily family use, it can be easily handled. Its compact and lightweight design allows users to carry it with them and enjoy the convenience it brings anytime and anywhere.

[0041] In addition, the utility model has good expansibility. Users can choose different accessories to combine according to their needs, so as to achieve more functions. For example, it can be matched with portable seats, tables, etc. to meet different usage needs. At the same time, the operation steps are simplified, the dangerous accidents that may be caused by improper operation are reduced, and the personal safety of users is guaranteed.

[0042] In general, the utility model realizes the lightness, convenience and safety of the product by improving the folding structure and operation method.
