[0020] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalents also fall within the scope of the claims appended hereto.

[0021] The embodiment of the present utility model relates to a portable child pedal stroller, such as Figure 1-5 As shown, it includes a frame 1, a front wheel assembly movably inserted at the front end of the frame 1, a rear wheel assembly arranged at the rear end of the frame 1, and a seat 6 arranged at the upper end of the frame 1, and also includes a rear basket 9. The rear end of the frame 1 is installed with an insert tube 11, and a detachable push rod assembly 8 is inserted into the insert tube 11. A long strip of guide plates 20 are installed on both sides of the insert tube 11, and an arc-shaped guide surface 24 is provided on the upper end of the guide plate 20. A conical column 19 is installed on the outer side of the lower part of each guide plate 20, and the diameter of the conical column 19 gradually increases from top to bottom. A notch 15 is opened on the upper part of the rear basket 9, and a docking sleeve 16 is installed on both sides of the notch 15 and is sleeved on the outside of the corresponding conical column 19. A slit 17 is opened on the side of the docking sleeve 16, and the slit 17 is connected to the inner hole of the docking sleeve 16, and the guide plate 20 is inserted along the slit 17.

[0022] The detachable push rod assembly 8 is a conventional technical means. Most of the strollers on the market have this function, so it will not be elaborated in detail.

[0023] When installing the rear basket 9, first align the slits 17 on the sides of the two docking sleeves 16 with their respective guide plates 20 and insert them. The cooperation between the guide plates 20 and the inner walls of the slits 17 allows the two docking sleeves 16 to be accurately sleeved on the outside of the corresponding conical cylinders 19. The diameter of the conical cylinder 19 gradually increases from top to bottom. The inner hole of the docking sleeve 16 is a straight hole with a constant hole diameter. As the conical cylinder 19 is continuously inserted into the docking sleeve 16, the outer wall of the conical cylinder 19 and the inner hole of the docking sleeve 16 are tightened, thereby fixing the position of the rear basket 9 and eliminating the traditional structure of fixing with fasteners, which facilitates disassembly and assembly. The slits 17 not only guide the guide plates 20, but also enable the docking sleeve 16 to have a certain deformation and expansion capacity.

[0024] The front wheel assembly includes a front fork 2, a front wheel 3 and a handlebar 5. The front fork 2 is rotatably mounted on the front end of the frame 1. The front wheel 3 and a pedal 4 for controlling the front wheel 3 are mounted on the lower part of the front fork 2. The handlebar 5 for controlling the steering of the front wheel 3 is mounted on the front fork 2.

[0025] A cup holder 14 is provided at the middle of the front end of the front fork 2 , and the cup holder 14 is used for placing a cup or a bottle.

[0026] The rear wheel assembly includes a rear fork shaft 7 and a rear wheel 10. A rear fork shaft 7 is installed on each side of the lower part of the rear end of the frame 1. A rear wheel frame 25 is installed at the end of the two rear fork shafts 7. A rear wheel 10 is rotatably installed on each side of the rear wheel frame 25. A support rod 26 is provided between the middle parts of the two rear fork shafts 7. A locking structure that cooperates with the support rod 26 is installed at the lower part of the insert tube 11; the locking structure includes a rotating seat 21, a hook 22 and a spring 27. A rotating seat 21 is installed at the lower part of the insert tube 11, and a rotatable hook 22 and a spring 27 for assisting the hook 22 to return to its original position are installed in the rotating seat 21. An armrest 23 is provided on the outer side of the upper part of the hook 22, and the hook portion of the lower part of the hook 22 hooks the support rod 26.

[0027] When the rear fork shaft 7 needs to be folded, hold the handrail 23 with your hand and rotate the hook 22 so that the hook portion at the lower part of the hook 22 is separated from the support rod 26, so that the rear fork shaft 7 can be rotated relative to the frame 1, and the two rear fork shafts 7 and the frame 1 are folded together, which can reduce the occupied space and facilitate transportation; when the cart needs to be used, bend the rear fork shaft 7 outward so that the hook portion at the lower part of the hook 22 is hooked on the support rod 26, and the elastic force of the spring 27 allows the hook 22 to keep the state hooked on the support rod 26, so that the rear fork shaft 7 and the frame 1 are in the unfolded state. Figure 1 The following figure shows the normal use of the cart.

[0028] A rotating plate 30 is provided on the inner side of the upper part of the hook 22, which is inserted into the rotating seat 21 and rotatably connected to the rotating seat 21. An arc-shaped opening 31 is opened at one end of the rotating plate 30, and a limiting column 29 is provided on the inner wall of the upper part of the arc-shaped opening 31. One end of the spring 27 is sleeved on the limiting column 29, and a baffle 28 is also provided inside the rotating seat 21 to abut against the other end of the spring 27; the spring 27 is limited by the cooperation of the baffle 28 and the limiting column 29.

[0029] A backrest 12 and a canopy 13 are installed on the rear side of the seat 6 , and the canopy 13 covers the backrest 12 .

[0030] A reinforcing rib 18 is further provided between the side of the docking sleeve 16 and the rear basket 9 .

[0031] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0032] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.
