Description

Technical Field

[0001] This invention relates to the field of baby stroller technology, and more particularly to a height-adjustable and foldable baby stroller adapter. Background Technology

[0002] Baby strollers are a common tool for people to travel with their babies, freeing up parents' hands and providing comfort for infants. To meet the travel needs of infants of different ages, existing baby strollers are equipped with adapters to facilitate simultaneous use as car seats, infant carriers, and seats, allowing for free switching and meeting multi-functional needs. However, most existing strollers on the market require users to install them themselves when in use and then disassemble them for separate storage when not in use, which is inconvenient and can easily lead to the loss of the adapter over time. Therefore, there is a need to design a stroller that does not require the removal of the adapter, is height-adjustable, and can be quickly folded for storage, meeting different usage needs and preventing the adapter from being lost. Summary of the Invention

[0003] The purpose of this invention is to provide a height-adjustable and foldable baby stroller adapter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A height-adjustable and foldable stroller adapter, which is mounted on a stroller frame and allows for the detachable installation of an infant seat, includes two main bodies, left and right. The main bodies are rotatably mounted on the stroller frame via a rotating seat, and a mounting seat is provided on the top of each main body for installing the infant seat. The main body has a rotating groove, and the rotating seat has a rotating part, a locking plate and a sliding part. The main body is rotatably mounted on the rotating part, and its rotation angle is adjusted by the locking plate moving within the rotating groove. The frame has a lifting rail, and the lifting rail has a locking slot along the rail. The sliding part is slidably mounted on the lifting rail, and the sliding part is movably mounted with a locking block that engages with the locking slot to restrict its movement. The mounting base has a limiting opening and a limiting block is movably installed thereon. The baby seat is mounted on the mounting base by a mounting cap and is locked in place with the limiting block.

[0005] Furthermore, the rotating groove is provided with multiple outer locking teeth, each of which is arranged in a circle at equal intervals. The rotating part is provided with a plate groove opposite to the rotating groove, the structure of which is adapted to the locking plate. The locking plate is provided with multiple inner locking teeth. The locking plate moves between the plate groove and the rotating groove. The locking plate is embedded in the rotating groove. The rotation of the main body is restricted by the engagement of the inner locking teeth and the outer locking teeth. The restriction is released when the engagement is disengaged.

[0006] Furthermore, the rotating part is provided with a connecting tube, the clamping plate and the rotating groove are provided with connecting ports, the clamping plate is sleeved on the connecting tube and moves along it, and the end of the connecting tube is inserted into the connecting port of the rotating groove and fixed by screws.

[0007] Furthermore, the main body has a button port on the other side of the rotating groove. The button port has a control port that communicates with the rotating groove, and a button for controlling the movement of the card plate is movably installed in the button port.

[0008] Furthermore, the button includes a cover plate and a push foot. The cover plate covers the button opening, and the push foot is fixedly connected to the cover plate and passes through the control opening to abut against the card plate. The push foot has a locking part that engages with the inner wall of the rotating groove, and the rotating part has an elastic element for pushing the card plate closer to the main body.

[0009] Furthermore, the sliding part is provided with a slider and a control block that are slidably installed with the lifting rail, the sliding part is provided with two tube holes, and the slider is provided with a tube body that is inserted into the tube hole.

[0010] Furthermore, the sliding part has two connected upper openings and side openings, the slider has a movable opening that aligns with the side opening, the control block is movably mounted on the upper opening, and an adjustment part is provided at its bottom. The locking block is movably mounted on the side opening and moves in and out of the movable opening. The locking block has mating parts on both sides that cooperate with the adjustment part. By pressing the control block, the adjustment part pushes the mating parts and the locking block back into the side opening, and the locking block disengages from the locking opening.

[0011] Furthermore, the mounting base is provided with a movable groove and a movable component. A block is provided in the movable groove, and the block is provided with an adjustment port. The movable component is movably installed in the movable groove, moves up and down along the movable groove, and is provided with a protrusion for limiting movement in the adjustment port. The bottom of the movable component is provided with an upward pushing part that cooperates with the limiting block, and the limiting block is provided with a downward pushing part that cooperates with the upward pushing part.

[0012] Furthermore, the mounting cap is rotatably mounted on the infant seat, and has a mounting opening at its bottom that is compatible with the mounting seat. The top of the mounting cap has an opening and a push block is movably mounted thereon. Pressing the push block downwards and pressing down on the movable part causes the movable part to push the limiting block back into the limiting opening and release the mounting cap from its latching state.

[0013] Furthermore, the mounting cap is provided with a card interface that engages with the limiting block.

[0014] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention features a lifting rail on the frame with a locking slot. The main body of the adapter is rotatably mounted on the lifting rail via a rotating seat. The position of the locking plate is controlled to fold and rotate the main body, meeting the needs of rotation at different angles. This allows for folding and storage without removing the adapter. The sliding part of the rotating seat slides along the lifting rail, and the locking block engages with the locking slot to restrict its movement. This allows the adapter to be raised and lowered to meet the needs of different functions.

[0015] 2. The main body of the adapter of the present invention is installed with the mounting cap of the baby seat. The movable part cooperates with the limiting block to push it to engage with the mounting cap for limiting installation. To release the engagement, simply press the push block to push the movable part downward and push the limiting block back into the limiting port to release the engagement. The baby seat can then be removed. It is ingenious to use and easy to operate. Attached Figure Description
