Description

Technical Field

[0001] This utility model relates to the field of baby product technology, specifically to a lifting and adjusting structure for a baby stroller bassinet. Background Technology

[0002] Baby strollers are common baby products. To ensure flexibility, some strollers are designed with height adjustment devices, meaning the bassinet can be adjusted vertically to meet different needs. However, most existing lifting mechanisms use simple sliding connections. Unlike industrial equipment, baby strollers are not equipped with metal rails, but rather use a plug-in method. During lifting, the plug-in structure cannot slide completely along the sliding direction, which will cause some wear and tear and is not conducive to long-term use. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed lifting and adjusting structure for a baby stroller bassinet, which addresses the defects and shortcomings of the existing technology and solves the aforementioned deficiencies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes telescopic kits installed on both sides of the bassinet of the stroller, and a mounting component for connecting the stroller frame is provided below the telescopic kit. The mounting component is slidably inserted into the telescopic kit. A connecting seat is provided inside the telescopic kit and is connected to the bassinet through the connecting seat. A movable locking mechanism is provided on the connecting seat.

[0005] Preferably, the movable locking mechanism includes an unlocker installed on the bassinet, a rotating inner core rotatably installed inside the unlocker, a handle connected to the rotating inner core, a control wire rope connected to the rotating inner core, a slider for unlocking slidably installed laterally inside the connecting seat, and a groove opened in the connecting seat, through which the control wire rope passes and connects to the slider.

[0006] Preferably, a locking block is slidably installed inside the connecting seat, a locking part is connected to the front end of the locking block, two locking tongues are connected to the front end of the locking part, the locking tongues are set towards the telescopic kit, the mounting part has matching holes, and multiple sets of locking holes are opened on the rear side of the mounting part along the vertical direction, the locking tongues are inserted into one set of locking holes, and the slider is connected to the locking block by transmission.

[0007] Preferably, the connecting seat has a transverse groove for sliding the slider and a longitudinal groove for sliding the locking block. The rear end of the locking block is provided with a spring. The transverse groove and the longitudinal groove are perpendicular to each other. The top surface of the locking block has a movable groove through which the slider passes. The slider has a driving inclined surface on its side and a driven inclined surface on one side of the movable groove. When the slider slides in the transverse groove, it drives the locking block to slide along the longitudinal groove through the inclined surface.

[0008] Preferably, the telescopic kit has fixed wheels on both sides of its bottom, with a gap between the fixed wheels and the mounting component, and movable wheels on both sides of the top of the mounting component, with a gap between the movable wheels and the sliding groove inside the telescopic kit.

[0009] Preferably, both ends of the control wire rope are connected to anti-slip blocks, which are respectively locked in the rotating inner core and the slider.

[0010] The beneficial effects of this utility model after adopting the above structure are:

[0011] 1. This application uses an unlocking device, which can be unlocked by controlling the steel wire rope through the handle. After release, it can be quickly reset and locked. The height of the sleeping basket can be adjusted with the key hole. The operation is simple and convenient.

[0012] 2. This application uses two sets of rollers to maintain the gap with the mounting parts during the lifting process, maintain the stability of sliding, prevent excessive compression or excessive friction, and ensure the long-term stability of the trolley. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figure 1 - Figure 8 As shown, it includes telescopic kits 3 installed on both sides of the bassinet 1 of the stroller. The telescopic kits 3 have mounting parts 2 for connecting to the stroller frame below. The mounting parts 2 are slidably inserted into the telescopic kits 3. The telescopic kits 3 have connecting seats 4 inside and are connected to the bassinet 1 through the connecting seats 4. The connecting seats 4 have a movable locking mechanism. The movable locking mechanism includes an unlocker 5 installed on the bassinet 1. A rotating inner core 7 is rotatably installed inside the unlocker 5. A handle 6 is connected to the rotating inner core 7. A control wire rope 8 is connected to the rotating inner core 7. A slider 11 for unlocking is slidably installed in the connecting seat 4. A groove 10 is opened in the connecting seat 4. After the control wire rope 8 passes through the groove 10, it is connected to the slider 11. Anti-slip blocks 9 are connected to both ends of the control wire rope 8. The anti-slip blocks 9 are respectively locked in the rotating inner core 7 and the slider 11. A locking block 13 is slidably installed inside the connecting seat 4. A locking part 18 is connected to the front end of the locking block 13. Two locking tongues 19 are connected to the front end of the locking part 18. The locking tongues 19 are set towards the telescopic kit 3. The mounting part 2 has a matching hole. Multiple sets of locking holes 20 are opened on the rear side of the mounting part 2 along the vertical direction. The locking tongue 19 is inserted into one set of locking holes 20. The slider 11 is connected to the locking block 13. The connecting seat 4 has a transverse slide groove 17 for sliding the slider 11 and a longitudinal slide groove 15 for sliding the locking block 13. The rear end of the locking block 13 is provided with a spring 23. The transverse slide groove 17 and the longitudinal slide groove 15 are perpendicular to each other. The top surface of the locking block 13 has a movable groove 16, through which the slider 11 passes. The side of the slider 11 is provided with a driving inclined surface 12, and one side of the movable groove 16 is provided with a driven inclined surface 14. When the slider 11 slides in the transverse slide groove 17, it drives the locking block 13 to slide along the longitudinal slide groove 15 through the inclined surface. The telescopic kit 3 has fixed wheels 21 on both sides of its bottom, with a gap between the fixed wheels 21 and the mounting part 2. The mounting part 2 has movable wheels 22 on both sides of its top, with a gap between the movable wheels 22 and the sliding groove inside the telescopic kit 3.

[0017] When lifting or lowering is required, lever 6 will rotate the inner core 7, which in turn pulls the control wire rope 8. Figure 6Taking the perspective as an example (the "up" and "down" below refer to the vertical direction in the diagram), at this time, the control wire rope 8 drives the slider 11 to slide to the left. The slider 11 then pushes the driven inclined plane 14 to slide through the driving inclined plane 12, causing the locking block 13 to slide downwards. This causes the locking tongue 19 at the front end of the locking block 13 to exit the lock hole 20. At this time, the mounting part 2 can slide up and down within the telescopic kit 3. The height can be adjusted by moving the sleeping basket 1 and the telescopic kit 3 up and down. After releasing the handle 6, the spring 23 rebounds, the locking block 13 slides forward, the handle 6 returns to the initial angle, and then the locking tongue 19 inserts into the lock hole 20 to lock the height. Figure 9 The state shown.

[0018] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.
