[0019] like Figures 1 to 3As shown, the present invention provides an angle-adjustable child safety seat, comprising a seat 1 and a backrest 2, wherein an adjustment device 3 for adjusting the angle of the backrest 2 is connected between the seat 1 and the backrest 2. The adjustment device 3 comprises a fixing plate 34, an extension rod 35, a first pulley 31, a rotating shaft 33, a second pulley 32, a fixing plate 38, and an insertion rod 37. One end of the extension rod 35 is fixedly connected to the seat 1, and the lower side of the backrest 2 is hinged to the extension rod 35. One end of the fixing plate 34 is fixedly connected to the seat 1, and one side of the fixing plate 38 is fixedly connected to the fixing plate 34. The rotating shaft 33 passes through the fixing plate 34 and the fixing plate 38 and is rotatably connected thereto, thereby fixing the fixing plate 34 and the fixing plate 38 to the rotating shaft 33. The rotating shaft 33 passes through the seat 1 and is fixedly connected thereto, so that the rotating shaft 33 drives the seat 1 to rotate. The rotating shaft 33 passes through the first pulley 31 and is fixedly connected to the first pulley 31, and the first pulley 31 drives the rotating shaft 33 to rotate. The insertion rod 37 passes through the first pulley 31 and is slidably connected to the first pulley 31. A plurality of sockets 8 are provided on one side of the fixed disk 38, and the plurality of sockets 8 correspond to the insertion rods 37. The insertion rods 37 are inserted into the sockets 8 to prevent the first pulley 31 from rotating. One side of the second pulley 32 is rotatably connected to the seat 1. A belt 36 is connected between the first pulley 31 and the second pulley 32. Rotating the second pulley 32 rotates the first pulley 31 through the belt 36. A handle 9 is fixedly connected to the side of the second pulley 32, and a plurality of anti-slip strips 7 are connected to the outside of the handle 9 to prevent slipping. A headrest 6 is connected to the upper part of the chair back 2.

[0020] There are two extension rods 35, and a cross bar 4 is connected between the two extension rods 35. A telescopic rod 5 is connected between the cross bar 4 and the chair back 2. The connection between the telescopic rod 5, the cross bar 4 and the chair back 2 is hinged. The telescopic rod 5 supports the chair back 2 and increases the stability of the chair back 2.

[0021] The above scheme operates as follows: To adjust the angle of the chair back 2, the rod 37 is pulled out to allow the chair back 2 to move. The handle 9 is turned to rotate the second pulley 32, which, via the belt 36, rotates the first pulley 31 and the rotating shaft 33, which in turn rotates the chair back 2. When the chair back 2 is adjusted to the desired angle, the rod 37 is inserted into the socket 8 to secure the first pulley 31 and the rotating shaft 33, thus fixing the angle of the chair back 2.

[0022] The above scheme has the following beneficial effects: the angle of the chair back 2 is adjusted by the adjusting device 3 to adapt to the sitting posture requirements of the child; the first pulley 31 and the chair back 2 are rotated by rotating the second pulley 32, and when the position is determined, the insertion rod 37 is inserted into the socket 8 to fix the angle of the chair back 2; the telescopic rod 5 is used to provide support force to the chair back 2 to increase the stability of the chair back 2.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
