The rotating column 312 is provided with a positioning slot 313 and a second locking slot 314 communicated with the positioning slot 313. The positioning slot 313 is communicated with the first slot 111 through the second slot 314, the positioning seat 700 is slidably disposed in the positioning slot 313, and the second slot 314 and the first slot 111 are located on a moving path of the positioning seat 700. The elastic member 600 is installed in the positioning groove 313 and is used for applying a first elastic force to the positioning seat 700 along a predetermined linear direction perpendicular to the rotation axis of the rotating seat 300 so that the positioning seat 700 sequentially penetrates into the second locking groove 314 and the first locking groove 111. The predetermined linear direction is a radial direction of the rotation column 312. Under the effect of elastic component 600, positioning seat 700 pierces through second draw-in groove 314 and first draw-in groove 111 in proper order to can prevent to rotate post 312 and rotate, realize the location of rotating seat 300, and then realize the location of seat 400. When the seat 300 needs to be rotated to adjust the orientation of the seat 400, an external force is applied to drive the positioning seat 700 to slide, the positioning seat 700 leaves the first clamping groove 111, the positioning seat 700 is located in the first clamping groove 111 and the positioning groove 313, the elastic member 600 is stressed, and the rotating column 312 can freely rotate, so that the rotation adjustment of the seat 400 is realized. After the external force is removed, the elastic member 600 is deformed, and the positioning seat 700 sequentially penetrates into the second engaging groove 314 and the first engaging groove 111, and the rotating column 312 is locked again.

Specifically, in some embodiments, the adjustable seat stroller further comprises a press seat 800; the fixing base 100 is further provided with a driving groove 112; the pressing base 800 is slidably mounted in the driving groove 112 along a predetermined linear direction, the positioning groove 313, the second locking groove 314, the first locking groove 111 and the driving groove 112 are sequentially arranged along the predetermined linear direction and in a direction away from the rotating base 300, the positioning groove 313, the second locking groove 314, the first locking groove 111 and the driving groove 112 are sequentially communicated, and the positioning base 700 is located on a moving path of the pressing base 800. The pressing base 800 slides backwards, the pressing base 800 extrudes the positioning base 700 to slide backwards and extrude the elastic piece 600, the positioning base 700 retracts into the second clamping groove 314 and the positioning groove 313, so that the pressing base 800 can rotate, the positioning base 700 is reset and clamped into the second clamping groove 314 and the first clamping groove 111 again to realize the positioning of the rotating base 300.

Specifically, in some embodiments, there are a plurality of pressing bases 800, positioning grooves 313 and second card slots 314, and the plurality of pressing bases 800, the plurality of positioning grooves 313 and the plurality of second card slots 314 correspond to one another; the plurality of second catching grooves 314 are circumferentially spaced along the rotational axis of the rotary holder 300. After the rotary base 300 rotates to a certain angle, the positioning is realized by the pressing base 800 at the corresponding position. For example, there are two pressing bases 800, positioning grooves 313 and second locking grooves 314, the rotating base 300 can be positioned and locked every 180 degrees, there are four pressing bases 800, positioning grooves 313 and second locking grooves 314, and the rotating base 300 can be positioned and locked every 90 degrees.

Specifically, in some embodiments, the elastic member 600 is a spring; one end of the spring abuts against the inner wall of the positioning groove 313, and the other end of the spring abuts against the positioning seat 700. The axis of the spring coincides with the sliding direction of the pressing base 800. The spring is clamped between the positioning socket 700 and the inner wall of the positioning groove 313.

Specifically, in some embodiments, the positioning seat 700 includes a limiting block and a positioning rod for being inserted into the first card slot 111 and the second card slot 314, and the positioning rod is located on a moving path of the pressing seat 800. The limiting block slides in the positioning groove 313 but does not pass through the first locking groove 111 and the second locking groove 314, so that the positioning seat 700 is prevented from being separated from the positioning groove 313.

Specifically, in some embodiments, the adjustable-seat stroller further includes a stopper plate 113 having a through hole 114; the pressing base 800 has a sliding member installed in the driving groove 112 and a pressing member protruding out of the driving groove 112 through the through hole 114. The sliding piece is abutted against the positioning rod, and the user presses down the pressing piece by hand to drive the sliding piece to slide.

Specifically, in some embodiments, the adjustable seat stroller further comprises a T-shaped carriage 900; the seat 400 has a mounting cavity and a through groove extending along a predetermined trajectory and communicating with the mounting cavity; one end of the T-shaped sliding frame 900 is connected with the rotating base 300, and the other end of the T-shaped sliding frame 900 passes through the through groove and is located in the installation cavity and abuts against the inner wall of the installation cavity. The T-shaped carriage 900 may prevent the rotary base 300 from being separated from the seat 400 when the seat 400 slides back and forth on the rotary base 300.

Specifically, in some embodiments, the predetermined trajectory is an arc trajectory, the sliding slot 311 is an arc slot, and the sliding plate 410 is a strip-shaped plate extending along the predetermined trajectory. The front end and the rear end of the arc groove are higher than the middle area of the arc groove, so that the tilting angle of the seat 400 can be adjusted when the seat 400 is movably adjusted forwards and backwards.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
