[0034] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0035] like Figure 1-11 As shown, the utility model is an angle-adjustable seat, comprising a seat body 1 and a seat adapter 14 rotatably arranged on both sides of the seat body 1 for connecting to a child stroller frame, a gear control locking mechanism 2 for limiting the seat body 1 to a corresponding gear position and a gear release mechanism 3 for linking the unlocking action of the gear control locking mechanism 2 are arranged between the seat body 1 and the seat adapter 14, an angle fine-tuning locking mechanism 4 for adjusting the inclination angle of the seat body 1 relative to the seat adapter 14 and an angle release mechanism 5 for linking the unlocking action of the angle fine-tuning locking mechanism 4 are also arranged between the seat body 1 and the seat adapter 14; the angle fine-tuning locking mechanism 4 is configured to adjust the inclination angle of the seat body 1 relative to the seat adapter 14 when the gear control locking mechanism 2 limits the seat body 1 to a corresponding gear position. During adjustment, the gear release mechanism is operated to release the gear control locking mechanism in conjunction with the gear control locking mechanism, and the angle release mechanism is operated to release the gear control locking mechanism in conjunction with the angle fine-tuning locking mechanism. At this moment, the locking state of the seat body relative to the seat adapter is released, and then the seat body is operated to rotate relative to the seat adapter to the desired gear position, and the gear release mechanism unlocks the gear control locking mechanism, so that the gear control locking mechanism restricts the seat body to the corresponding gear position. At this moment, the unlocking action of the angle release mechanism on the angle fine-tuning locking mechanism can be directly canceled, or the seat body can continue to be operated to rotate relative to the seat adapter to fine-tune the inclination angle of the seat body, and then the unlocking action of the angle release mechanism on the angle fine-tuning locking mechanism can be canceled, thereby completing the adjustment operation of the seat body. For this reason, the utility model can facilitate users to quickly restrict the seat body to the desired gear position, and then continue to adjust and fine-tune the inclination angle of the seat body to provide a more comfortable riding environment for the occupant, and has the characteristics of convenient adjustment and comfortable use.

[0036] When the seat needs to be folded, the gear control locking mechanism 2 and the angle fine-adjusting locking mechanism are released at the same time, and the seat body 1 can be operated to rotate and fold relative to the seat adapter 14.

The corresponding end of the gear locking protrusion 221 is blocked and limited with the two end walls of the gear limiting arc groove 21, so that the seat body can be limited to be fine-tuned within a set range.

[0039] like Figure 7 , 8 As shown, a slider guide structure 6 for guiding the movement path of the gear locking slider 22 is provided between the gear locking slider 22 and the seat joint seat 13. The slider guide structure 6 includes a slider guide slot 61 provided on the seat joint seat 13 and extending along the axial direction thereof, and a slider guide protrusion 62 provided on the gear locking slider 22 and guidingly matched with the slider guide slot 61, which is conducive to the gear locking protrusion smoothly snapping into the gear limiting arc groove, ensuring the smooth cooperation between the two and ensuring the smooth adjustment of the seat.

In this embodiment, the angle release member 53 drives the angle release dials 51 on the left and right sides of the seat body to rotate through the corresponding angle release pull rope 52 to synchronously release the angle fine-tuning locking mechanism 4 on the left and right sides of the seat body, thereby improving the unlocking efficiency. When it is necessary to fine-tune the seat body, the user pulls the angle release member 53 by hand to move relative to the seat body 1, and the angle release member 53 drives the angle release dial 51 to rotate through the angle release pull rope 52, and the angle release dial 51 and the angle release inclined portion 511 of the angle locking gear 42 cooperate with each other to drive the angle locking gear 42 to move axially toward the seat adapter 14 and separate from the angle locking groove 41 of the seat joint seat 13, and then operate the seat body 1 to rotate relative to the seat adapter 14 to fine-tune the required tilt angle, release the angle release member 53, at this moment, the gear locking elastic member 43 drives the angle locking gear 42 to elastically reset so that the angle locking gear 42 is simultaneously engaged in the seat joint seat 13 and the angle locking groove 41 of the seat adapter 14 to lock the seat body 1 relative to the seat adapter.
