When the stroller is to be unfolded for use, the frame 300 is unfolded, and then the seat 200 is mounted with respect to the frame 300 using the snap structure 100. Such setting, the normal use of the perambulator of not only being convenient for, the accommodation of the perambulator of being convenient for reduces the occupation space of perambulator moreover, improves the convenience in use.

It should be noted that, since the seat 200 needs to have a process of detachment and attachment with respect to the frame 300, the excellent connection performance of the engaging structure 100 directly affects the performance of the seat 200 assembly with respect to the frame 300. An embodiment of the present invention further provides a locking structure 100, which is convenient to operate and can ensure that the seat 200 is stably and timely matched with the frame 300.

As shown in fig. 1 to 12, in particular, the fastening structure 100 provided in this embodiment includes a fastening seat 10 connected to a frame 300 and a fastening assembly 20 connected to a seat 200. The engaging assembly 20 includes an engaging arm 21, a pushing arm 22 connected to the engaging arm 21, and an acting arm 23 connected to the pushing arm 22, wherein a first elastic element 241 is connected between the pushing arm 22 and the acting arm 23. In the first state, the acting arm 23 can move to the position where the first elastic element 241 is compressed under the pushing force of the latch seat 10, and the latch arm 21 can move toward the side close to the latch seat 10, so that the latch arm 21 can be locked with the latch seat 10. In the second state, the pushing arm 22 can drive the clamping arm 21 to move reversely, the clamping arm 21 can be unlocked relative to the clamping seat 10, and the first elastic element 241 moves synchronously with the pushing arm 22, so that the first elastic element 241 can be clamped with the acting arm 23.

The first state is a state in which the seat 200 needs to be assembled with respect to the frame 300, and the second state is a state in which the seat 200 needs to be disassembled with respect to the frame 300.

As shown in fig. 1-4, when the seat 200 needs to be installed relative to the frame 300, the user needs to hold the seat 200 with his/her hand, move the seat 200 downward relative to the frame 300, and as the seat 200 moves downward relative to the frame 300, the latch assembly 20 connected to the seat 200 approaches the latch seat 10, and when the acting arm 23 in the latch assembly 20 contacts the latch seat 10, the latch seat 10 applies an upward pushing force to the acting arm 23, so as to urge the acting arm 23 to move to a position where it presses the first elastic element 241. Simultaneously, along with being close to of block subassembly 20 relative joint seat 10, joint arm 21 can move towards the one side that is close to joint seat 10 to cooperate with the joint of joint seat 10, realize the locking of the relative joint seat 10 of joint arm 21, thereby realize the joint cooperation between this block subassembly 20 and the joint seat 10, also realize the assembly of the relative frame 300 of seat 200. When the acting arm 23 moves to a position where the first elastic element 241 is compressed, the first elastic element 241 between the acting arm 23 and the pushing arm 22 is compressed, and is elastically deformed to generate elastic potential energy.

As shown in fig. 1, 5, 6 and 7, when it is necessary to detach the seat 200 from the frame 300, the pushing arm 22 is actuated to drive the engaging arm 21 to move reversely, so that the engaging arm 21 is disengaged from the engaging seat 10, i.e. the engaging arm 21 is unlocked from the engaging seat 10, and the user can hold the seat 200 with his hand and move up relative to the frame 300. At this time, the engaging arm 21 is also in the unlocked state with respect to the pushing arm 22.
