[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 A children's dining chair with adjustable height includes a fixed bracket 1, the internal rotation connection of the fixed bracket 1 is connected to a rotating shaft 2, the outer surface of the rotating shaft 2 is fixedly installed with a movable bracket 3, the internal fixed bracket 1 is fixedly installed with a slide rod 4, the outer surface of the slide rod 4 is slidably connected with a slider 5, the outer surface of the slider 5 is fixedly installed with a dining chair body 6, a dining board 7 is provided on the left side of the dining chair body 6, a limiting groove 8 is provided on the outer surface of the slide rod 4, a button 9 is movably connected to the right side of the slider 5, a pin 10 is provided inside the slider 5, and a brake block 11 is provided on the outside of the fixed bracket 1.

[0021] Specifically, such as Figure 1 As shown, after use, the movable bracket 3 is retracted to be flush with the fixed bracket 1 through the rotating shaft 2, thereby reducing the space required for storage, and then the stability of the two fixed brackets 1 and the two movable brackets 3 is ensured by the provided first connecting rod and the second connecting rod, and then the slider 5 sliding outside the slide rod 4 is limited by the provided limit block to prevent it from exceeding the range of movement.

[0022] Specifically, such as Figure 1 As shown, the material of the spring body is beryllium bronze, which contains 1.7-2.5% beryllium. The addition of beryllium has excellent elasticity. Beryllium bronze is a precipitation hardening alloy with good strength, hardness, elasticity and fatigue resistance. Beryllium bronze springs can still maintain excellent mechanical properties at high temperatures.

[0023] Specifically, such as Figure 1As shown, a rubber plate is provided at the bottom of the two movable brackets 3 to increase the friction between the device and the ground to prevent displacement and the like during use. The main component of the rubber plate is natural rubber, which has excellent elasticity and wear resistance. The rubber plate is processed by a special process to make its surface rougher, thereby increasing the friction with the ground and effectively preventing the seat from sliding, providing children with a stable and safe dining or playing environment. At the same time, the rubber plate has a certain elasticity. When the seat is subjected to external force, it can quickly return to its original shape and absorb part of the impact force, reducing the movement of the seat and further ensuring the safety of the child.

[0024] During implementation, follow these steps:

[0025] 1) First, the movable bracket 3 is driven to separate from the fixed bracket 1 by the rotating shaft 2, so that the device can be deployed for use and fixed by the brake block 11;

[0026] 2) Then press the two buttons 9 to cooperate with the spring body to pull the two latches 10 out of the limiting grooves 8 and retract them into the interior of the slider 5;

[0027] 3) Slide the slider 5 again to drive the dining chair body 6 to move along the slide bar 4, thereby adjusting the height of the dining chair body 6;

[0028] 4) Finally, release the two buttons 9. Under the action of the spring body, the two latches 10 are inserted into the limiting grooves 8 to fix the position.

[0029] To sum up, when the height-adjustable children's dining chair is in use, the movable bracket 3 is driven to separate from the fixed bracket 1 to form a triangle by the rotation of the rotating shaft 2, and is fixed in position by the brake block 11. Then, by pressing the two buttons 9 at the same time, the two pins 10 can be pulled out from the limiting grooves 8 on the outer surfaces of the two slide rods 4 in cooperation with the spring body, and temporarily retracted into the interior of the slider 5. Then, the dining chair body 6 is driven to move along the outer surface of the slider 4 by sliding the slider 5, so as to adjust the height of the dining chair body 6. When it is adjusted to the appropriate height, release the two buttons 9 and, under the action of the spring body, send the two pins 10 out of the interior of the slider 5 again, and insert them into the corresponding limiting grooves 8 on the outer surfaces of the two slide rods 4, respectively, so as to achieve the purpose of easy height adjustment and easy storage.
