[0015] like Figure 1-2 The utility model provides a folding stroller for children, comprising a base frame, a wheel 1 arranged at the lower end of the base frame, a folding frame arranged at the upper end of the base frame and a seat 2 arranged on the folding frame, the base frame comprises a front roller frame 3 and a rear roller frame 4 arranged oppositely, a cross column 5 and a cross bar 6 arranged between the front roller frame 3 and the rear roller frame 4, both ends of the cross column 5 and the cross bar 6 are fixed to the middle of the front roller frame 3 and the rear roller frame 4 and spaced up and down, and the wheels 1 are respectively arranged at the lower ends of the front roller frame 3 and the rear roller frame 4;
[0016] Wheels are installed at the lower ends of the front roller frame 3 and the rear roller frame 4. There are four wheels, two at the front and two at the rear. The cross column 5 and the cross bar 6 are double-rod supports, which have higher strength and better load-bearing performance. With the four wheels, the balance is better. The seat 2 adopts a simple seat pocket structure and is lighter.
[0017] The folding frame includes a cross frame 7 and a telescopic vertical rod 8 arranged in a cross shape, and a sliding seat 9 slidably arranged on the cross column 5 and the cross bar 6. The telescopic vertical rod 8 and the cross frame 7 are hinged at the cross position. The seat 2 is arranged between the front end of the cross frame 7 and the upper end of the telescopic vertical rod 8. The rear end of the cross frame 7 is hinged to the rear roller frame 4, and the front end is connected to the lower end of the seat 2. The lower end of the telescopic vertical rod 8 is hinged to the sliding seat 9, and the upper end is connected to the upper end of the seat 2. The back of the seat 2 is connected to the telescopic vertical rod 8 at the corresponding position. The sliding seat 9 is provided with two sliding holes and is adapted to the cross column 5 and the cross bar 6. The sliding seat 9 is slidably mounted on the cross column 5 and the cross bar 6 with the help of the two sliding holes.
[0018] The telescopic upright 8 is a telescopic rod structure, and the sliding seat 9 is slidably connected to the cross column 5 and the cross bar 6 at the same time, so the sliding is more stable. When folding, the upper end of the telescopic upright 8 is swung forward, and the lower end of the telescopic upright 8 slides backward on the cross column 5 and the cross bar 6 until the telescopic upright 8 and the cross frame 7 are placed flat on the bottom frame. At this time, the front end of the telescopic upright 8 is pushed back to complete the folding. The seat 2 is a simple seat pocket structure made of cloth, which does not hinder folding, or can be directly removed before folding. This design adopts a simple structure with stable structure, excellent load-bearing performance, simple folding operation, small volume after folding, easy to carry, low production and assembly difficulty, and low cost.
[0019] like Figure 1-2 The cross frame 7 includes symmetrically arranged support rods 10, the rear ends of the support rods 10 are hinged to the rear roller frame 4, the front ends of the support rods 10 are bent and tilted outward and are respectively connected to the two corners on the lower side of the front end of the seat 2, and the telescopic vertical rods 8 pass through between the support rods 10.
[0020] The support rod 10 is composed of two support rods 10, and the telescopic vertical rod 8 passes through the support rods 10 and is connected by a hinge structure. The front end of the support rod 10 is bent and tilted outward, and the two corners on the lower side of the front end of the seat 2 are connected, so that the load-bearing force is more uniform and the stability is stronger.
[0021] like Figure 1-2 The telescopic upright rod 8 has a C-shaped frame 11 with its opening facing forward fixed on its upper end, and the upper end of the seat 2 is connected to the C-shaped frame 11 .
[0022] The C-shaped frame 11 is used to fix the left and right sides of the upper end of the seat 2, so that the load-bearing force is more uniform and the stability is stronger. In addition, the C-shaped frame 11 can also be used as a handle for pushing the seat 2, which is very convenient to use.
[0023] like Figure 1-2 Said, a sun visor 12 is arranged on the upper end of the seat 2 .
[0024] The sun visor 12 can provide shade for children riding in the seat 2 to prevent direct sunlight.
[0025] like Figure 1-2 The cross column 5 and the cross bar 6 are also provided with an outer cover 13, and the upper end of the outer cover 13 is provided with a long slot hole 14. The sliding seat 9 is located in the outer cover 13 and the upper end extends upward from the long slot hole 14 and is hinged to the lower end of the telescopic vertical rod 8.
[0026] The outer cover 13 is fixed between the front roller frame 3 and the rear roller frame 4, and the cross column 5 and the cross bar 6 are located in the outer cover 13. The outer cover 13 can protect the sliding seat 9, the cross column 5 and the cross bar 6 to avoid collisions that affect the sliding stability and smoothness. The long slot hole 14 can limit the sliding range of the sliding seat 9, that is, limit the swing range of the telescopic vertical rod 8, which plays a role of reminding that it is in place, and is more convenient to use.
[0027] like Figure 1-2 The rear end of the rear roller frame 4 is provided with a handle 15 .
[0028] After being folded, the handle 15 can be conveniently carried, making it easy to transport the cart.
