[0016] In order to explain the technical content, purpose and effect of the utility model in detail, the following is an explanation in combination with the implementation mode and the accompanying drawings. In the description of the implementation mode, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the implementation mode and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0017] like Figure 1 and 2As shown, the structure includes a child seat support plate 1, a rear connecting rod 2, a tooth plate 3, a locking block 4, a pneumatic spring 5, a rear mounting bracket 6, a cable 7, a front mounting bracket 8 and a front connecting rod 9. The front end of the seat support plate 1 is rotatably connected to the front mounting bracket 8 through the front connecting rod 9, and the rear end of the seat support plate 1 is rotatably connected to the rear mounting bracket 6 through the rear connecting rod 2. The end of the rear connecting rod 2 connected to the rear mounting bracket 6 is fixedly provided with a tooth plate 3, and the end of the rear mounting bracket 6 connected to the rear connecting rod 2 is provided with a locking block 4. The tooth plate 3 is locked and fixed by the locking block 4, one end of the cable 7 is connected to the locking block 4, and the other end is provided on the front mounting bracket 8. Pulling the end of the cable 7 on the front mounting bracket 8 can drive the cable 7 to contract, thereby driving the locking block 4 to disengage from the tooth plate 4.

[0018] As a preferred embodiment of the above embodiment, Figure 1-2 As shown, the number of the rear connecting rods 2 is two, and the corresponding matching cables 7, tooth plates 3 and locking blocks 4 are also two, which are arranged in parallel between the rear mounting bracket 6 and the rear end of the seat support plate 1.

[0019] As a preferred embodiment of the above embodiment, Figure 1-2 As shown, it also includes a pneumatic spring 5 and a rear cross bar 10. The rear cross bar 10 is arranged parallel to the lower rear end of the seat support plate 1. The end of the rear cross bar 10 is fixed to the rear connecting rod 2. The middle part of the rear cross plate 10 is connected to one end of the pneumatic spring 5, and the other end of the pneumatic spring 5 is fixed to the front mounting bracket 8.

[0020] After the installation is complete, Figure 3 The adjustment and matching form for children of different ages is shown as follows: the unlocking cable 7 is pulled at the front end of the seat cushion, the locking block 4 is unlocked, and the rear connecting rod 2 is lifted under the action of the pneumatic spring 5. After reaching the height required by children of different age groups, the cable is released, and the locking block 4 locks the tooth plate 4, thereby achieving height fixation. When resetting, just unlock the cable 7, press down the seat cushion, so that the locking block 4 is aligned with the starting point of the upper tooth plate 4, release the cable, and the locking block 4 locks the tooth plate 4, thereby achieving resetting. The adjustable height travel of the tooth plate 4 is 0-65mm, which can meet the riding height requirements of children aged 2-12.

[0021] The utility model integrates a child seat on the basis of a car seat and can be adjusted according to children of different ages and heights, thereby reducing the use cost and being easy to carry.

[0022] Although the present invention has been described in detail above with specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention.
