[0002] Folding chairs are generally composed of a seat, a backrest, legs and a folding mechanism. The seat is the part that a person contacts when sitting down, and is usually made of a strong material such as canvas, leather or plastic. The backrest provides back support, and its height, angle and material vary depending on the design to meet the comfort needs of different users.

[0003] At present, there are many types of folding chairs on the market, but some folding chairs have the problems of complex structure and inconvenient operation. For example, a Chinese patent, an outdoor portable automatic locking folding chair, application number CN202020771761.8, in the process of storage, the movable lock sleeve is pulled up, the lock extension piece of the lock catch is separated from the movable lock sleeve, then the backrest support pipe is directly lifted up, the U-shaped connecting piece and the seat cushion support pipe at the bottom side of the backrest support pipe are moved up, the middle side of the backrest support pipe drives the armrest pipe, the armrest pipe drives the front leg pipe and the rear leg pipe to rotate, and the front leg pipe, the rear leg pipe and the armrest pipe are gradually retracted and close together. It can be seen that the operation process of the folding chair is relatively complicated, and the user needs to perform multiple steps to complete the storage or unfolding operation of the folding chair, which increases the difficulty of use. SUMMARY

[0004] Therefore, the utility model provides a folding high chair with self-locking and simple operation to meet the industrial needs.

[0005] The self-locking folding high chair comprises two symmetrical handrail supports, a first folding assembly arranged between the handrail supports, two second folding assemblies arranged between the handrail supports, and two limiting rods arranged at one end of the second folding assemblies respectively. The first folding assembly comprises two first folding supports hinged to the handrail supports. Each first folding support comprises a first folding support body arranged on the handrail support, and a first folding support connecting piece arranged at an end of the first folding support body away from the handrail support. The ends of the two first folding supports are hingedly connected to the handrail supports respectively, and the first folding support connecting pieces of the two first folding supports are hingedly connected to each other. Each second folding assembly comprises two second folding supports arranged between the handrail supports, and two connecting rods hingedly connected between the second folding supports and the handrail supports. The two second folding supports are arranged in a cross shape and are hingedly connected to each other, and the centers of the two second folding supports are hinged positions. One end of each second folding support is hingedly connected to the handrail support, and the other end of the second folding support is fixedly connected to the limiting rod. One end of each connecting rod is hingedly connected to the handrail support, and the other end of the connecting rod is hingedly connected to one end of the second folding support close to the limiting rod. When the self-locking folding high chair is in an unfolded state, the free ends of the two first folding supports are combined together, and the two limiting rods abut against one side of the handrail support respectively, thereby limiting the rotation of the second folding assembly, and achieving the automatic locking of the second folding assembly and the first folding assembly.

[0006] Further, each handrail support comprises a handrail body and a backrest support arranged on the handrail body.

[0007] Further, the handrail body has a rectangular outer contour.

[0009] Further, a first anti-skid pad is arranged at the bottom of each handrail support.

[0010] Further, a second anti-skid pad is arranged on the first folding support body.

[0011] Further, when the self-locking folding high chair is in the unfolded state, one end of the two first folding supports is combined together, and the sum of the lengths of the two first folding supports is equal to the width of the handrail support in the unfolded state.

[0012] Compared with the prior art, the self-locking folding high chair provided by this utility model can drive the armrest support to fold through the first folding assembly and the second folding assembly, and the first folding assembly and the limiting rod. Two first folding brackets in the first folding assembly are respectively hinged to the armrest support. Each first folding bracket includes a first folding bracket body on the armrest support, and a first folding bracket connector disposed at the end of the first folding bracket body away from the armrest support. The first folding bracket connector is disposed at the bottom of the first folding bracket body, and the ends of the two first folding brackets facing away from the armrest support are connected together by the first folding bracket connector. Each second folding assembly includes two second folding brackets disposed between the armrest support, and two connecting rods hinged between the second folding brackets and the armrest support. The two second folding brackets are arranged crosswise and hinged together. One end of each second folding bracket is hinged to the armrest support, and the other end of the second folding bracket is fixedly connected to the limiting rod, realizing the opening and closing of the second folding assembly. Each connecting rod has one end hinged to the armrest bracket and the other end hinged to the end of the second folding bracket near the limiting rod, thus restricting the position of one end of the second folding bracket. When the self-locking folding high chair is in the unfolded state, one end of the two first folding brackets merges together, the two first folding brackets are connected horizontally, and the free ends of the two first folding brackets merge together, achieving a limiting between the two first folding brackets. The sum of the lengths of the two first folding brackets is equal to the width of the two armrest brackets in the unfolded state, thus limiting the distance between the two armrest brackets. The two limiting rods abut against one side of one armrest bracket, thereby restricting the rotation of the second folding assembly. Thus, the user only needs to open the self-locking folding high chair to achieve automatic locking of the second folding assembly and the first folding assembly, ensuring the stability of the self-locking folding high chair when unfolded. It can be seen that the self-locking folding high chair is simple to operate, convenient to use, and automatically locks after unfolding, possessing good stability and load-bearing capacity.
