Description

Technical Field

[0001] This utility model relates to the field of unlocking mechanisms for strollers, and particularly to an unlocking mechanism for baby strollers. Background Technology

[0002] To make the shoelaces on the baby stroller easier to fit, the size of the stroller during transport needs to be minimized. To make the stroller easier to fold, a combination of locking and unlocking mechanisms is required. Existing unlocking mechanisms are relatively complex and prone to malfunction during use, leading to unlocking or locking failure. Utility Model Content

[0003] The main purpose of this utility model is to provide an unlocking mechanism for a baby stroller.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An unlocking mechanism for a baby stroller includes a fixed base, a housing, and a pinching part. The housing is fixedly mounted on the stroller frame, and the fixed base is fitted inside the housing. Sliding limiting grooves are fixedly formed on both end faces of the fixed base. Movable connecting blocks are slidably mounted within these sliding limiting grooves. A first inclined guide surface is formed on the movable connecting block. A button connection part is provided on either the fixed base or the housing, or either of them. A sliding connecting groove is formed on the housing, and a pinching part is slidably mounted within this groove. One end of the pinching part extending into the sliding connecting groove has a second inclined guide surface that matches the first inclined guide surface. The first and second inclined guide surfaces are slidably connected. The pinching part drives two movable connecting blocks to move in opposite directions via the second inclined guide surface. A pull cord fixing groove is formed on each movable connecting block.

[0006] Furthermore, a limiting part is provided on one side of the sliding limiting groove, and a rope groove for the pull rope to pass through is provided on the limiting part. The limiting part is located at the opposite end of the unlocking and moving direction of the movable connecting block.

[0007] Furthermore, a button connection groove is provided on one side of the fixed base, and a button body is slidably installed in the button connection groove. A locking groove matching the button body is provided on the pinch part, and one end of the button body slides out of the locking groove to the outer shell.

[0008] Furthermore, a limiting arm is fixedly provided on one side of the button connection groove, and a limiting protrusion is provided at the end of the limiting arm. A longitudinal limiting groove matching the limiting arm is provided on the button body.

[0009] Furthermore, the button connection groove is provided with a spring positioning protrusion, and a reset spring is provided on the spring positioning protrusion, with the other end of the reset spring placed inside the button body.

[0010] Furthermore, the button body includes an integrally formed button body, a limiting guide portion and a pressing portion. A clearance groove is provided between the pressing portion and the button body. An irregularly shaped recess is provided on one side of the button body to form the limiting guide portion. The button connecting groove has the same cross-sectional shape as the limiting guide portion and the button body.

[0011] Furthermore, a limiting member is fixedly provided inside the outer shell. The limiting member is fixedly connected to the fixed base by screws. A connecting guide groove is provided on the upper end face of the limiting member. A connecting protrusion matching the connecting guide groove is provided on the fixed base. A spring guide protrusion is fixedly provided between the lower end face of the limiting member and the inside of the pinching part. A reset spring is provided between the two spring guide protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the pinching part moves in the direction of the fixed base under force, the second inclined guide surface of the pinching part cooperates with the first inclined guide surface to drive the movable connecting block to move in opposite directions, thereby driving the rope to pull closer to unlock the folding switch of the handcart frame. The structure is simple and the folding and unlocking is achieved through the sliding cooperation of the two inclined guide surfaces, which is practical and convenient. Attached Figure Description
