Description

Unlocking mechanism for folding sleeping basket, folding sleeping basket and baby carriage Technical Field The utility model relates to a child walker, in particular to an unlocking mechanism for a folding sleeping basket, the folding sleeping basket and a baby carriage. Background Some strollers on the market are very popular with consumers because they can be used to mount both a child seat and a sleeping basket to carry younger infants. Most of the existing folding sleeping baskets are provided with cloak which can be used for shading sun and rain, when the folding sleeping basket needs to be folded, the folding sleeping basket can be folded after the supported cloak support is unlocked, and therefore operation is complex. In the patent application 2024112926283, the first upper frame and the second upper frame can be folded in half and then stored after the cloak bracket is unlocked and folded. Disclosure of utility model The utility model aims to solve the technical problem that in the prior art, folding of a sleeping basket needs to be carried out in two steps, and the sleeping basket is not convenient to store, and provides an unlocking mechanism for folding the sleeping basket, the folding sleeping basket and a baby carriage. The utility model solves the technical problems by the following technical scheme: An unlocking mechanism for folding a sleeping basket comprises a first rotating member and a second rotating member, wherein the first rotating member comprises a first main body and a locking member, the first rotating member and the locking member synchronously rotate around an axial direction (X), the first main body is provided with a first clamping groove, the locking member is configured to move in the first clamping groove along the axial direction (X) between a first position and a second position, the locking member comprises a lock pin part, the second rotating member comprises a second main body and a pushing block, the second rotating member and the pushing block synchronously rotate around the axial direction (X), the second main body is provided with a second clamping groove and a locking groove, the pushing block is provided with a pushing part, the pushing block is configured to move in the second clamping groove along the axial direction (X) between a third position and a fourth position, the locking member is abutted with the pushing part, in some specific embodiments, the locking member is clamped in the locking groove when being subjected to the acting force of an elastic member in the first position, the third rotating member is provided with a slope surface matched with the pushing part, and when the second rotating member and the third rotating member rotate around the axial direction (X) are in a tangential direction, and the pushing part is enabled to move towards the second position from the first position to the fourth position and the pushing part is enabled to move towards the second position (X) along the axial direction. In this aspect, when the locking member is in the first position, the lock pin portion is engaged in the lock groove, and the locking member cannot rotate around the axial direction (X). In addition, since the first rotating member and the locking member rotate synchronously around the axial direction (X), the first catching groove and the locking member are restricted from each other, and when the locking member cannot rotate, the first rotating member cannot rotate. When the second rotating piece and the third rotating piece relatively rotate, the inclined surface is in tangential contact with the pushing part and applies axial (X) acting force to the pushing part, so that the pushing block moves from the third position to the fourth position along the axial direction (X). The locking piece is abutted with the pushing block, and moves from the first position to the second position to be separated from the locking groove under the action of the pushing block. At this time, the locking member can be rotated about the axial direction (X), i.e., the first rotation member can be rotated while unlocking is achieved. The locking piece of first rotating member and the locking groove cooperation of second rotating member form the locking, and the inclined plane drive ejector pad of third rotating member is along axial displacement, promotes the locking piece and breaks away from the locking groove, promptly through the relative rotation of second rotating member and third rotating member, realizes the automatic unblock of first rotating member, need not the first rotating member of individual operation, and the unblock process is convenient and reliable and stable. In addition, since the cloak bracket is connected with the first rotating member, the first upper frame body is connected with the second rotating member, and the second upper frame body is connected with the third rotating member. The locking piece of the first rotating piece is matched with th
