[0023] Please refer to Figure 1 -Figure 5 In the embodiment, the fixed sleeve 33 is provided with a clamping groove at the relative position of the sliding sleeve 34, the sliding sleeve 34 is clamped and connected on the clamping groove, the rotation of the fixed sleeve 33 is limited by clamping the sliding sleeve 34 on the clamping groove, so as to avoid the rotation of the fixed sleeve 33 driving the sliding block 37 to retract and make the clamping rod 313 disengage from the clamping of the clamping sleeve 315 when the clamping rod 313 is clamped with the clamping sleeve 315. The clamping sleeve 315 is provided with a clamping groove at the relative position of the clamping rod 313, and the clamping rod 313 is clamped and connected on the clamping groove. The rotation of the wheel 2 is limited by clamping the clamping rod 313 on the clamping sleeve 315, so as to avoid the situation of rolling car. The main fixed seat is composed of the first fixed shell 41 and the second fixed shell 42, the first fixed shell 41 and the second fixed shell 42 are connected by bolts, the axle body 1 and the rotating shaft 31 are both rotationally connected on the first fixed shell 41, the sliding sleeve 34 is slidingly connected on the sliding sleeve 34, the first thrust spring 35 is fixedly connected between the sliding sleeve 34 and the second fixed shell 42, the sliding sleeve 34 is provided with a pushing force by the first thrust spring 35, the sliding sleeve 34 is pushed to be more stably clamped with the fixed sleeve 33, and the sliding sleeve 34 is further prevented from being disengaged from the fixed sleeve 33, so as to avoid the fixed sleeve 33 driving the clamping rod 313 to disengage from the clamping sleeve 315 and cause the wheel 2 to roll and slide. The second fixed shell 42 is provided with a sliding groove at the relative position of the sliding sleeve 34, and the sliding sleeve 34 is slidingly connected on the sliding groove. The rotation of the sliding sleeve 34 is limited by the sliding groove, so as to avoid the sliding sleeve 34 from being disengaged from the second fixed shell 42 and affecting the clamping of the fixed sleeve 33. The brake fixed seat is composed of the first brake seat shell 51 and the second brake seat shell 52, the first brake seat shell 51 and the second brake seat shell 52 are connected by bolts, the first brake seat shell 51 and the second brake seat shell 52 are arranged on the axle body 1, the sliding block 37 is slidingly connected on the second brake seat shell 52, the second thrust spring 38 is fixedly connected between the sliding block 37 and the first brake seat shell 51, the guide wheel 310 is rotationally connected on the second brake seat shell 52, and the fixed clamping block 311 is fixedly connected on the second brake seat shell 52. The sliding block 37 is provided with a pushing force by the second thrust spring 38, the sliding block 37 is pushed to be more stably clamped with the clamping rod 313, and the sliding block 37 is better limited to rotate the wheel 2. The second brake seat shell 52 is provided with a sliding groove at the relative position of the sliding block 37, and the sliding block 37 is slidingly connected on the sliding groove. The sliding of the sliding block 37 is limited by the sliding groove, so as to avoid the sliding block 37 from being disengaged from the second brake seat shell 52 and affecting the clamping of the clamping rod 313 and the clamping sleeve 315.
[0024] In the process of working, the first brake seat shell 51 and the second brake seat shell 52 are connected by bolts during installation, and then connected with the axle body 1, and then the axle body 1 is installed between the first fixed shell 41 and the second fixed shell 42, and then the first fixed shell 41 and the second fixed shell 42 are screwed, and then the main fixed seat is connected with the stroller body, so as to complete the installation of the structure. When the wheel 2 needs to be restricted, the guardian steps on the brake pedal 32, and when the brake pedal 32 rotates, the fixed shaft sleeve 33 rotates, and at this time, the sliding shaft sleeve 34 is pushed outwards through the sliding groove, and when the fixed shaft sleeve 33 rotates to a certain angle, the sliding shaft sleeve 34 corresponds to the other clamping groove position of the fixed shaft sleeve 33, and the first push spring 35 provides a pushing force to the sliding shaft sleeve 34, pushing the sliding shaft sleeve 34 to slide to the original place, and re-clamping with the fixed shaft sleeve 33 to restrict the rotation of the fixed shaft sleeve 33. When the fixed shaft sleeve 33 rotates, the connecting wire disc 36 is driven to rotate, and the short traction rope 39 is temporarily released, and at this time the second push spring 38 provides a pushing force to the sliding block 37, pushing the sliding block 37 to slide on the second brake seat shell 52, driving the clamping rod 313 to slide out of the clamping with the clamping shaft sleeve 315 on the wheel 2, so as to complete the restriction of the wheel 2. At this time, the guardian can move freely, and when the restriction of the wheel 2 is to be released, the guardian pushes the brake pedal 32 again, driving the fixed shaft sleeve 33 and the connecting wire disc 36 to rotate again, and when the connecting wire disc 36 rotates, the first traction rope 39 is pulled, and the guide wheel 310 cooperates with the first traction rope 39 to guide the first traction rope 39, and the sliding block 37 is pulled to slide on the second brake seat shell 52, so that the clamping rod 313 is retracted into the brake fixing seat and is released from the clamping with the clamping shaft sleeve 315. In this way, the wheel 2 can move again, and the guardian can push the stroller to continue moving.
[0025] Through the above steps, when the stroller is used, especially in the shopping scene, the user temporarily leaves to find the goods, and if the stroller is not held, the stroller will move and slide, and the rotation of the wheel 2 is restricted by the clamping rod 313 and the clamping shaft sleeve 315, so as to solve the problem that the stroller lacks restriction and slides when the guardian needs to be away from the stroller, and finally causes bumping, even the child falls and causes injury.
