As shown in fig. 3 and 7, the locking element 271 includes a locking pin 2711 capable of moving transversely with respect to the frame 1, the pushing portion 28 includes an arc-shaped protrusion 281 circumferentially disposed on the connecting portion 26, and the arc-shaped protrusion 281 is provided with a protrusion slope 282 capable of contacting the locking pin 2711 to push the locking pin 2711 to exit from the locking groove 272 when the connecting portion 26 rotates. Therefore, when the backrest 22 rotates, the boss inclined surface 282 contacts with the latch 2711, and the boss inclined surface 282 presses the latch 2711 outwards during the continuous rotation of the backrest 22, so that the latch 2711 is separated from the locking groove 272, and the unlocking of the seat 2 and the frame 1 is completed. The operation is very convenient and fast, and the design is ingenious.

As shown in fig. 3, 4 and 6, a vertical engaging platform 274 is disposed on the frame 1, a vertical engaging groove 275 having an opening at a lower end and capable of engaging with the vertical engaging platform 274 is disposed on the connecting seat 25, and the bayonet 2711 is disposed in the frame 1 and capable of extending out of the vertical engaging platform 274. When the seat 1 is coupled to the frame 1, the vertical catching groove 275 is caught to the vertical catching table 274, so that the seat 2 is hung to the frame 1, and then the bayonet 2711 is laterally inserted into the locking groove 272, so that the seat 2 is more firmly locked to the frame 1.

As shown in fig. 3, a bayonet 2711 is provided with a bayonet slope 2712 which can be pressed by the edge of the connecting portion 26 when the vertical engaging groove 275 and the vertical engaging platform 274 are engaged with each other. Therefore, when the seat 2 is connected with the frame 1, when the seat 2 is installed from the top to the bottom, the edge of the connecting part 26 touches the bayonet 2712 and presses the bayonet 2711, and when the seat 2 is completely hung on the vertical clamping platform 274, the bayonet 2711 is pushed by the first spring 273 to reset and is clamped in the locking groove 272, and the whole installation process of the seat 2 is very convenient and fast.

As shown in fig. 6 and 8, the connection seat 25 includes an outer connection seat 251 for connecting with the frame 1 and an inner connection seat 252 for fixing the seat rod 211, the inner connection seat 252 is rotatably connected with the outer connection seat 251, an arc-shaped limit boss 253 is arranged on the inner connection seat 252 along the circumferential direction, and a limit groove 254 capable of being matched with the limit boss 253 to limit the inner connection seat 252 is formed between the outer connection seat 251 and the connection portion 26. When the seat 2 is connected with the frame 1, the outer connecting seat 251 is fixedly connected with the frame 1, and the inner connecting seat 252 can rotate a certain angle relative to the outer connecting seat 251, so that the seat rod 211 can also rotate towards the backrest 22 to be closed, the rotating angle range is controlled through the limiting boss 253 and the limiting groove 254, and the folding size of the baby carriage framework can be ensured to be smaller and more compact.

As shown in fig. 8, the backrest locking device 23 includes a plurality of locking grooves 231 provided on the connecting seat 25 along the circumferential direction, the backrest 22 is provided with a locking rod 232 capable of being engaged with or disengaged from the locking groove 231, the backrest 22 is further provided with a handle 233, a pull cable 234 for connecting the handle 233 and the locking rod 232 and pulling the locking rod 232 out of the locking groove 231 when the handle 233 rotates is further provided between the handle 233 and the locking rod 232, and the backrest 22 is further provided with a second spring 235 capable of keeping the locking rod 232 and the locking groove 231 engaged when the backrest is unfolded. When the seat locking device 27 needs to be unlocked, the handle 233 is only required to be rotated, the locking rod 232 is pulled out of the locking groove 231 through the pull cable 234, the handle 233 is arranged on the backrest 22, an infant is difficult to touch, the seat 2 and the frame 1 cannot be unlocked by mistake, and safety is ensured. Moreover, the plurality of locking grooves 231 are provided, and the included angle of the backrest 22 can be adjusted by inserting the locking rod 232 into different locking grooves 231, so that the infant can sit in a comfortable position. Of course, other locking structures in the prior art can be used for the backrest locking device 23, and will not be described in detail herein.
