DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments; in the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, the description of known functions and structures is omitted.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0029] like Figure 1-7 As shown, a baby walker provided by the present embodiment includes an upper tray 100, a lower chassis 200 and a support assembly 300. The lower chassis 200 is located below the upper tray 100. The support assembly 300 is arranged between the upper tray 100 and the lower chassis 200. A universal wheel 400 is provided at the bottom of the lower chassis 200. The support assembly 300 includes a folding box 310, a short frame 320, a long frame 330 and an adjusting block 340. One end of the short frame 320 is hinged to the bottom of the upper tray 100, and the other end is fixedly connected to the adjusting block 340. The adjusting block 340 is movably arranged inside the top of the folding box 310. One end of the long frame 330 is hinged to the middle and lower part of the folding box 310, and the other end is hinged to the bottom of the lower chassis 200. A groove 312 runs through the surface of the folding box 310 along the length direction, and both sides of the long frame 330 can enter or move out of the groove 312.

[0030] Specifically, when the walker of this embodiment is in normal use, the two sides of the long frame 330 are located in the grooves 312 of the folding box 310. When folding the walker, the two sides of the long frame 330 are moved out of the grooves 312, and then the long frame 330 is pressed downward to make the two ends of the long frame 330 rotate around the folding box 310 and the lower chassis 200 respectively. At the same time, the long frame 330 pulls the folding box 310 to move, and the folding box 310 drives the short frame 320 to move, and then the short frame 320 pulls the upper tray 100 to move downward until the upper tray 100 is folded to the inner side of the lower chassis 200, thereby realizing the folding of the walker. The folding structure of the walker of this embodiment is simple, so the production process is simpler, cost is saved, and the operation process is fast and convenient, which improves the convenience of folding the walker for users.

[0031] Furthermore, the long frame 330 of this embodiment includes two symmetrically arranged support rods 331, one end of the two support rods 331 being hinged to the lower chassis 200 is integrally connected, and there is a certain distance between the ends of the two support rods 331 and the folding box 310 being hinged; a rotating sleeve 311 is provided at the middle and lower part of the surface of the folding box 310, and the ends of the support rods 331 away from the lower chassis 200 are inserted into the rotating sleeve 311. The grooves 312 on the surface of the folding box 310 are arranged on both sides of the rotating sleeve 311, and the two support rods 331 can enter or move out of the grooves 312.

[0032] Specifically, the two support rods 331 of the long frame 330 are made of a material that can undergo plastic deformation and self-recovery. When folding, it is only necessary to press the two support rods 331 together with one hand to move the support rods 331 out of the grooves 312 of the folding box 310, thereby unlocking the long frame 330 and the folding box 310, and at the same time press the long frame 330 downward to perform the above-mentioned folding process. When the two sides of the long frame 330 are rotated out of the folding box 310, the force pressing the two support rods 331 together can be released, and the two support rods 331 return to their original state. The long frame 330 is arranged in this way, which facilitates the locking or unlocking between the long frame 330 and the folding box 310, thereby achieving the purpose of folding and folding the vehicle.

[0033] Furthermore, a button 313 is provided in the middle of the folding box 310 of the present embodiment, and a V-shaped single-bead shrapnel is provided in the adjusting block 340. The marble of the V-shaped single-bead shrapnel passes through the adjusting block 340, the folding box 310 and conflicts with the button 313. The V-shaped single-bead shrapnel is not shown in the figure, and the product selected is a common product on the market that can be directly purchased. Since the V-shaped single-bead shrapnel is already an existing well-known technology, the marble of the V-shaped single-bead shrapnel is moved out of the folding box 310 by pressing the button 313, thereby achieving unlocking between the folding box 310 and the adjusting block 340. This is also an existing well-known technology, and no drawings or text explanations are provided here; after unlocking, the adjusting block 340 can move in the folding box 310, so that people can adjust the position of the adjusting block 340 in the folding box 310 according to actual needs, and then adjust the height position of the upper tray 100 to adapt to children of different heights, so that the scope of use of the walker is wider.

[0034] Furthermore, the upper tray 100 of this embodiment is provided with an annular opening 110 for a child to enter, and a seat cover 500 is detachably mounted at the annular opening 110 for the child to sit on. A reinforcing frame 510 is inserted inside the seat cover 500 to facilitate the child to lean on when sitting, making the seat cover 500 safer and more comfortable to sit on.

[0035] Furthermore, a receiving groove 120 is provided on the upper tray 100 on the front side of the annular opening 110, and a dining plate is detachably installed in the receiving groove 120. The receiving groove 120 can be used to place toys for children to play with, and can also be used to install a dining plate for children to eat. The dining plate is set to be detachable for easy cleaning.

[0036] Furthermore, screw holes 210 are evenly distributed on the bottom of the lower chassis 200 of the present embodiment, and the screws on the wheel frame of the universal wheel 400 are screwed into the screw holes 210, so that disassembly and assembly are very convenient.

[0037] Furthermore, the bottom of the lower chassis 200 of the present embodiment is hinged with a limit support leg 600. When the child needs to stay in a certain position, the limit support leg 600 can be supported on the ground to limit the movement of the child.
