Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a children's scooter. Background Technology

[0002] Children's scooters are a favorite outdoor sport for kids, helping to develop balance and coordination while providing fun. Scooters typically consist of a base, seat, and handlebars. When using one, children sit on the seat, hold onto the handlebars, and glide along the ground with their feet. For safety reasons, some scooters are equipped with safety barriers to prevent children from falling off the seat. Additionally, two training wheels are installed on either side of the rear wheel. These wheels provide support when the user's center of gravity is too far back (e.g., during sudden braking or a sudden drop of the rear), preventing the scooter from tipping over and avoiding falls due to loss of balance. Furthermore, for beginners or young children, who are prone to swaying from side to side when starting or traveling at low speeds, the training wheels provide lateral support, reducing the risk of tipping over and helping users gradually master balance skills.

[0003] However, existing children's scooters have the following drawbacks in actual use: protective devices cannot be quickly disassembled or installed according to the user's situation. These added guardrails and training wheels are often fixed to the base plate or fixed by multiple bolts. Beginners need these guardrails and protective devices to ensure safety, but for some skilled children, the training wheels and guardrails actually affect play. The training wheels will greatly reduce the scooter's flexibility, so they cannot be quickly adapted to different children. Utility Model Content

[0029] To allow the rear buckle 12 to swing, the support frame 9 has a hinged pivot 18 on its right side that is fixed to the rear buckle 12.

[0030] To facilitate the reset of the rear latch 12, a torsion spring 19 is provided on the rotating shaft 18. One end of the torsion spring 19 is connected to the rear latch 12 and the other end is connected to the support frame 9.

[0031] To facilitate pressing the rear buckle 12, a pressure plate 20 is provided at the right end of the rear buckle 12.

[0032] For ease of use, the support frame 9 is provided with a wheel groove 21 located between the two auxiliary wheels 10, and the rear wheel 3 can be inserted into the wheel groove 21.

[0033] For ease of stability, the upper surface of the support frame 9 is arc-shaped and can be completely fitted with the lower surface of the base plate 1.

[0034] In order to fix and release the fixed buckle 14 and the movable buckle 17, a fixed block 22 is slidably connected to the front side of the fixed buckle 14. The upper end of the fixed block 22 is connected to the fixed buckle 14 via a spring. The movable buckle 17 is provided with a snap-fit ​​buckle 23 that can cooperate with the fixed block 22.

At this time, the disassembly of the protective rod 16 can be completed.

[0039] Then press down on the pressure plate 20. The pressure plate 20 will cause the rear buckle 12 to swing to the right. After swinging to the right at a certain angle, it will disengage from the locking block 8. At this time, pull down on the right side of the support frame 9 to disengage the rear buckle 12 from the bottom plate 1, thus releasing the fixed limit on the right side of the bottom plate 1. Then, at an angle of inclination, pull the front buckle 11 out from the limiting slot 7 to release the fixed limit on the support frame 9. The support frame 9 can then be removed. At this time, the disassembly of the protective device is complete. It is suitable for skilled children to play with. When installation is required, simply reverse the above process.

[0040] Compared with the prior art, the beneficial effects of this utility model are: the support frame, front buckle, and rear buckle can protect children while they play, preventing them from falling off the seat and tipping over. At the same time, the protective bar and auxiliary wheels can be quickly and easily disassembled, making it suitable for skilled children. Compared with the traditional fixed type, it can be transformed into different usage states according to different users. It is easy to operate and saves time and effort. This structure is simple, novel in design, convenient to use, and highly practical.

[0041] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.
