[0002] A baby carriage is a relatively common children's toy. It is highly playable and can significantly increase the amount of exercise a child does. It is more labor-saving than walking or being carried in the parents' arms when traveling long distances. Therefore, it is loved by children and parents.

[0003] There are many types of baby strollers in the prior art, but there is an obvious technical problem, that is, the seat height of almost all baby strollers on the market cannot be adjusted relatively easily, resulting in a poor experience for children when playing with friends and sharing a baby stroller. For this reason, we propose a baby stroller with an easy-to-adjust seat height. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a baby carriage with an adjustable seat.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] A seat plate, slidably connected to the vertical pipe;

[0012] A rotating rod, one end of which is rotatably connected to the connecting seat; the other end of which is movably connected to the seat plate;

[0013] The adjusting member is arranged on the seat plate and connected with the rotating rod. The user operates the adjusting member to move the rotating rod relative to the seat plate to realize lifting and lowering of the seat plate.

[0014] The utility model has the following beneficial effects:

[0015] When the height of the seat of the utility model needs to be adjusted, it is only necessary to rotate the knob to rotate the screw rod. The rotating screw rod drives the slider to move under the effect of the threaded cooperation, while the height of the other end of the rotating rod cannot be changed. Because the seat plate can only slide up and down relative to the vertical pipe, the rotating rod rotates to lift the seat upward to adjust the seat height. The whole operation is relatively simple, which is convenient for children to quickly adjust the height when playing with friends to obtain a better experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figures 1 to 3 The utility model provides a child stroller with an adjustable seat, which comprises a base 1, a roller 2, a connecting seat 3, a vertical pipe 4, a seat plate 6, a rotating rod 8, and an adjusting member.

[0022] The roller 2 is arranged on the base 1 for supporting the base 1 on the ground. The connecting seat 3 is fixed to the front upper wall of the base 1 . The vertical pipe 4 is fixedly connected to the upper wall of the connecting seat 3 . The connecting seat 3 supports the vertical pipe 4 .

[0023] A sliding sleeve 5 is fixedly connected to the seat plate 6, and the sliding sleeve 5 is slidably connected to the vertical tube 4; one end of the rotating rod 8 is rotatably connected to the connecting seat 3; the other end is movably connected to the seat plate 6; the seat plate 6 can only produce a deflection movement relative to the vertical tube 4, but cannot produce a pitching movement relative to the vertical tube 4.

[0024] Reference Figure 1 , Attachment Figure 2The adjusting member is arranged on the seat plate 6 and connected to the rotating rod 8. The user operates the adjusting member to move the rotating rod 8 relative to the seat plate 6 to realize the lifting and lowering of the seat plate 6. During this process, the adjusting member causes the rotating rod 8 to rotate, so that the height of one end of the rotating rod 8 changes, thereby pushing the seat plate 6 to move up, thereby realizing the seat height adjustment of the baby carriage.

[0025] Reference Figure 1 The rollers 2 include at least three, two rollers 2 are arranged at the front of the base 1, and one roller 2 is arranged at the rear of the base 1, so as to ensure that the whole baby carriage can move stably on the ground.

[0026] Reference Figure 1 The vertical tube 4 is threadedly connected to a handrail rod 7, the upper end of the handrail rod 7 is provided with a horizontal handrail, and the outer wall of the handrail rod 7 is provided with an external thread that cooperates with the threaded sleeve 9. When using the baby carriage, the user sits on the seat plate 6 and holds the horizontal handrail, and steps on the ground with both feet to make the baby carriage slide forward; when the height of the handrail rod 7 needs to be adjusted, the handrail rod 7 can be moved upward or downward relative to the vertical tube 4 by rotating it relative to the vertical tube 4, thereby realizing the adjustment of the height of the handrail rod 7.

[0027] Reference Figure 1 , Attachment Figure 2 The external thread of the handrail 7 is connected to a threaded sleeve 9. Since the handrail 7 is threadedly connected to the vertical pipe 4, the threaded sleeve 9 threadedly connected to the handrail 7 is provided in this embodiment to tighten the handrail 7. When the handrail 7 is adjusted to a desired height, the threaded sleeve 9 is rotated to make it tightly against the upper wall of the vertical pipe 4. At this time, the double nut tightening in the machine is realized to prevent the handrail 7 from easily rotating relative to the vertical pipe 4, thereby ensuring that the handrail 7 will not easily rotate when the user uses the baby carriage.

[0028] Reference Figure 3 A slide groove 11 is provided on the lower wall of the seat plate 6, and the adjusting member includes a slider 14 slidably connected in the slide groove 11, and the slider 14 is rotatably connected to one end of the rotating rod 8. A screw rod 12 is rotatably connected in the slide groove 11, and the screw rod 12 passes through the slider 14 and is threadedly connected thereto. The screw rod 12 passes through the side wall of the seat plate 6 and is fixedly connected thereto with a knob 13. When it is necessary to adjust the height of the seat plate 6, rotating the knob 13 can drive the screw rod 12 to rotate, and the rotation of the screw 12 drives the slider 14 matched therewith to slide in the slide groove 11, thereby changing the position of the end of the rotating rod 8 in the slide groove 11, that is, adjusting the pitch angle of the rotating rod 8, while the height of the other end of the rotating rod 8 remains unchanged, thereby changing the seat height, and achieving the purpose of seat height adjustment.

[0029] A slot 10 is provided on one side of the connection seat 3 , a rotating shaft is fixedly connected in the slot 10 , and one end of the rotating rod 8 is rotatably connected to the rotating shaft.

[0030] To sum up, in this embodiment, the seat plate 6 is used for users to sit on, that is, it has the function of a chair; when the seat height needs to be adjusted, it is only necessary to rotate the knob 13 to rotate the screw rod 12, and the rotating screw rod 12 drives the slider 14 to move through the thread, thereby causing the rotating rod 8 to rotate and lift the seat upward (or move downward), thereby achieving the adjustment of the seat height, and the whole operation is relatively simple.

[0031] It is further explained that: in order to prevent the user from touching the knob 13 and causing the seat height to change when getting on or off the stroller, the knob 13 is generally arranged close to the seat plate 6, that is, when the user moves, a small amount of friction between the knob 13 and the clothes cannot cause the knob 13 to rotate significantly; in other embodiments, the knob 13 is buried in the seat plate 6, and a handle connected to the knob 13 and easy to disassemble is also provided. These are all common technical means based on the present embodiment and should be understood to fall within the scope of protection of the present application.
