[0038] like Figures 1 to 7 As shown, a height adjustment mechanism for a baby carriage carrier comprises a frame and a carrier 1, connectors 101 are provided on both sides of the carrier 1, a sliding seat 3 which can slide relative to the push rod 2 of the frame to adjust the height position is provided, the sliding seat 3 has a locking member 4 which can achieve sliding locking between the sliding seat 3 and the frame when the sliding seat 3 is at different height positions; a mounting seat 5 for the connector 101 to be plugged and installed is provided on the sliding seat 3, the mounting seat 5 is communicated with the inner cavity of the sliding seat 3, an auxiliary locking block 6 is rotatably installed in the sliding seat 3, one end of the auxiliary locking block 6 can extend into or out of the plug-in slot of the mounting seat 5, and the other end is movably connected with the locking member 4.

[0039] In this embodiment, the push rod 2 of the frame is formed with a slide rail 201 along its extension direction, and the sliding seat 3 is arranged on the slide rail 201 and slides with it. Preferably, the locking member 4 is a sliding button, and the sliding seat 5 has a mounting groove for the locking member 4 to be installed and slide. The slide rail 201 has at least two slots 202 for the sliding button to lock in. The sliding button locks in or out of the corresponding slot 202 by sliding relative to the sliding seat 3, thereby realizing whether the sliding seat 3 and the frame push rod 2 are locked. In the figure of this embodiment, although only two slots 202 are marked on each side push rod 2, the number of the slots 202 can be set as needed to achieve the adjustment of different height gears.

[0040] In this embodiment, the sliding direction of the locking member 4 is arranged perpendicular to the sliding direction of the sliding seat 3. This direction setting is conducive to better locking between the sliding seat 3 and the frame, and the sliding operation of the locking member 4 is also more convenient.

[0041] In this embodiment, the middle part of the auxiliary lock block 6 is rotatably connected with the sliding seat 3, in a seesaw shape. The locking member 4 has a movable groove 401 on one side, and the other end of the auxiliary lock block 6 is located in the movable groove 401. When the auxiliary lock block 6 rotates, its embedded end can move in the movable groove 401, thereby realizing a movable connection with the locking member 4; when the plug-in member 101 of the carrier 1 is plugged and assembled with the mounting seat 5, the two ends of the auxiliary lock block 6 are respectively set against and clamped on the bottom of the plug-in member 101 and the upper end of the movable groove 401, at which time the auxiliary lock block 6 cannot rotate, and the locking member 4 cannot slide and unlock.

[0042] In this embodiment, the mounting seat 5 is opened upward, arranged longitudinally, and is integrally formed with the sliding seat 3. The arrangement of the mounting seat 5 facilitates the plug-in installation of the plug-in components 101 on both sides of the carrier 1, and a locking mechanism is often arranged between the two. The locking mechanisms between the plug-in structures are of various types and are common structures in the technical field, so they are not specifically limited or elaborated here.

[0043] The working principle of the utility model is:

[0044] When the connector 101 of the carrier 1 is not plugged and assembled with the mounting seat 5, the auxiliary locking block 6 is not clamped and can be rotated at will. At this time, the locking member 4 can achieve the locking of the sliding seat 3 and the frame by sliding; when the height of the carrier 1 needs to be adjusted, it is only necessary to slide the locking member 4 to unlock the lock between the sliding seat 3 and the frame, and then when the sliding seat 3 is slid to the desired position along the push rod 2, the locking member 4 is slid in the opposite direction to lock the sliding seat 4 with the frame.

[0045] When the connector 101 of the carrier 1 is plugged and assembled with the mounting seat 5, the connector 101 presses against the auxiliary locking block 6 to make it withdraw from the plug-in slot of the mounting seat 5 and be clamped between the connector 101 and the locking member 4. At this time, the auxiliary locking block 6 cannot rotate, and the other end of the auxiliary locking block 6 restricts the locking member 4 so that it cannot perform a sliding unlocking operation.

[0046] The utility model has a simple, novel and reliable structure, avoids accidental unlocking of the sliding seat 3 caused by mistakenly touching the locking member 4, and further improves the safety performance during use.

[0047] The height of the carrier 1 (seat or sleeping basket) of the utility model can be adjusted according to different usage needs, and it has a simple structure, a reliable principle, and is easy to operate. On the one hand, the infant in the carrier 1 (seat or sleeping basket) has a wider field of vision for observing the surrounding environment and objects, which increases the pleasure of the infant's growth. On the other hand, during the pushing process of the baby carriage, the distance between the infant and the parent can be shortened by raising the carrier 1 (seat or sleeping basket), which makes it convenient for the parent to maintain closer contact and better communication and interaction with the child, and at the same time allows the parent to easily carry the infant in or out of the baby carriage by just bending over slightly.
