Description
Technical Field
[0001] The utility model relates to a child stroller frame. Background Art
[0002] A child stroller is a tool vehicle designed to facilitate outdoor activities for infants and young children. It has long been widely used. To make the child stroller more convenient to carry and store, the child strollers on the market generally can be folded and unfolded. However, the frame structure of the existing child strollers is very complex, with many parts and high costs, resulting in inflexible folding. Moreover, after folding many times, the child stroller is easily damaged, and the folded volume is still relatively large. Summary of the Utility Model
[0003] To solve the above technical problems, the purpose of the utility model is to provide a child stroller frame with a simple structure, flexible folding, few folding parts, low cost, small volume after folding, and convenient for carrying and storing.
[0004] A child stroller frame proposed by the utility model, with the forward direction of the child stroller as a reference, includes a front bracket (1), a rear bracket (6), a push rod (3), a rear strut (4), a sliding sleeve (5) and a seat rod (2). The rear end of the front bracket, the front end of the rear bracket and the front end of the push rod are all hinged on the same hinge (7). The sliding sleeve is slidably sleeved on the rear bracket. One end of the rear strut is hinged on the push rod, and the other end is hinged on the sliding sleeve. The front end part of the seat rod is hinged on the front bracket, and the rear end part of the seat rod is hinged on the other end of the rear strut.
[0005] Further, it also includes a U-shaped curtain rod (11). The rear end of the U-shaped curtain rod is hinged on the front end part of the push rod, and the U-shaped curtain rod is located inside the push rod.
[0006] Further, the rear strut is located inside the rear bracket and the push rod.
[0007] Further, a rear wheel assembly (8) is installed at the rear end of the rear bracket, and a front wheel assembly (9) is installed at the front end of the front bracket.
[0008] Further, the front wheel assembly is a universal wheel assembly, the rear wheel assembly is a directional wheel assembly, and a foot brake (12) is provided on the rear wheel assembly.
[0009] Further, a frame unlocking button (10) is installed in the middle of the push rod.
[0010] By means of the above solution, the utility model has at least the following advantages: The child stroller frame has a simple structure, few folding parts, low cost, flexible folding, not easily damaged, small volume after folding, can stand, occupies little space, and is convenient to carry.
[0011] The above description is only an overview of the technical solution of the present utility model. In order to better understand the technical means of the present utility model and implement it according to the content of the description, the following describes in detail with reference to the preferred embodiments of the present utility model and the accompanying drawings. Brief Description of the Drawings

[0013] Figure 2 It is a schematic diagram of the folded state of the child stroller frame of the present utility model. Detailed Description of the Preferred Embodiments
[0014] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0015] Embodiment: A child stroller frame, with the forward direction of the child stroller as the reference, includes a front bracket 1, a rear bracket 6, a push rod 3, a rear strut 4, a sliding sleeve 5 and a seat rod 2. The rear end of the front bracket, the front end of the rear bracket and the front end of the push rod are all hinged on the same hinge 7. The sliding sleeve is slidably sleeved on the rear bracket. One end of the rear strut is hinged on the push rod, and the other end is hinged on the sliding sleeve. The front end portion of the seat rod is hinged to the front bracket, and the rear end portion of the seat rod is hinged to the other end of the rear strut.
[0016] It further includes a U-shaped curtain rod 11. The rear end of the U-shaped curtain rod is hinged to the front end portion of the push rod, and the U-shaped curtain rod is located inside the push rod.
[0017] The rear strut is located inside the rear bracket and the push rod.
[0018] The rear end of the rear bracket is equipped with a rear wheel assembly 8, and the front end of the front bracket is equipped with a front wheel assembly 9.
[0019] The front wheel assembly is a universal wheel assembly, the rear wheel assembly is a directional wheel assembly, and a foot brake 12 is provided on the rear wheel assembly.
[0020] A frame unlocking button 10 is installed in the middle of the push rod.
[0021] The folding method of the stroller frame is as follows: manually press the frame unlocking button to unlock it, and then push the push rod 3 downward to make the push rod move downward. The push rod drives the rear support rod 5 to move downward, and the rear support rod drives the sliding sleeve 7 to slide downward along the rear bracket 8, while driving the seat rod 2 to move upward. The seat rod drives the front bracket 2 to move backward, and both the front bracket and the push rod move closer to the rear bracket, thereby realizing the folding of the frame. Pull the U-shaped curtain rod by hand and pull the U-shaped curtain rod to a position parallel to the push rod through a damping movement. The frame has few folding joints, and the entire frame folding process can proceed smoothly, preventing large forces from occurring at each connection and avoiding damage.
[0022] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
