Description

Technical Field

[0001] The present invention relates to the technical field of template waste removal devices, and more particularly to an extensible baby furniture bed that can be adjusted according to the growth of a baby's body shape. Background Art

[0002] Baby furniture beds are the core facilities for infant care. Traditional baby beds generally adopt a fixed-size structure, which only fits babies of a relatively small age group, and there are problems such as short service life, low space utilization rate, and single function. With the development of parenting concepts towards refinement, the market's demand for long-cycle adaptable baby beds is becoming increasingly urgent, requiring the bed body to be dynamically adjusted according to the changes in the baby's height and activity ability.

[0003] After retrieval, the patent document with the publication number CN218246530U discloses an adjustable baby bed, which includes a bed board body. On both sides of the outer surface of the bed board body, there are extension bed board devices, and at the bottom of the outer surface of the bed board body, there is an arc-shaped support. The extension bed board device includes two extension boards, and on the top of the outer surface of both extension boards, there are bed rails fixedly connected. For this adjustable baby bed, by setting the extension bed board device, under the action of the extension boards, the extension boards can cooperate with the rectangular grooves and dovetail sliders on the inner wall of the bed board body, so that the extension boards can be pulled out from the inner wall of the bed board body or retracted into the inner wall of the bed board body, thereby enabling the size of the bed board body to be adjusted, and thus being applicable to babies of different body postures, and further preventing babies of different body postures from feeling embarrassed due to the too-small bed board body, and improving the baby's sleep experience.

[0004] However, the above invention has the following deficiencies: The above patent can achieve a certain bed surface expansion effect through the expansion device, but it can only achieve unidirectional expansion, while a baby grows in all directions. Therefore, when leaving the factory, only a relatively wide size can be reserved, resulting in inconvenient use. Moreover, it cannot adjust the height of the fence. As the baby's body shape grows and its activity ability gradually increases, there is a risk of the baby falling, so there are certain limitations. Summary of the Invention

A pair of bumps 26 are fixedly installed at the end of the extension plate 25. The bumps 26 are slidably matched with the adjusting grooves I 19. An adapter block 39 is slidably installed inside the adjusting grooves III 35. The adapter block 39 and the side sliding plate 8 are connected to each other through a movable shaft. The provided adjusting grooves I 19 and adjusting grooves III 35 can further limit and stabilize the movement of the side sliding plate 8 and the extension plate 25, thereby ensuring the stability of the adjustment process.

[0042] Further, a ventilation pipe 36 is fixedly connected between every two adjacent support sleeves 3. A T-shaped connecting pipe 37 is fixedly connected between the pair of ventilation pipes 36. A cut-off valve 38 is fixedly installed at the end of the T-shaped connecting pipe 37. The provided ventilation pipe 36 and T-shaped connecting pipe 37 can effectively control the air pressure inside the support sleeve 3. When the cut-off valve 38 is opened, the piston support column 4 can move normally under the action of the return spring 5. When the cut-off valve 38 is closed, it can ensure that the internal air pressure does not change, thereby realizing the locking effect on the piston support column 4, and further realizing the fixing effect on the bed board 2.

[0043] Specific working principle: First, open the cut-off valve 38 and place the baby on the bed board 2. Under the action of the baby's own gravity, the bed board 2 can be driven to move downward. As the bed board 2 moves downward, the protection component can be driven to move upward through the cable 16 and the fixed pulley 13, thereby improving the protection effect and avoiding the risk of the baby falling, thus improving the protection effect on the baby. When the bed board 2 moves downward to a certain position, close the cut-off valve 38. By controlling the constant air pressure inside the support sleeve 3, the locking effect on the piston support column 4 can be realized, and then the fixing effect on the bed board 2 can be realized, ensuring the stability of the bed board 2 during the turning process of the baby. When the device needs to be adjusted, through the hexagon wrench, the bidirectional threaded rod 27 can be easily rotated by using the provided hexagonal mounting block 34, thereby driving the extension plate 25 to move, and then widening the length of the bed board 2. Then, through the bevel gear transmission, the bidirectional threaded rod 27 can drive the adjusting screw 29 to rotate, and then drive the connecting slider 32 to move. By using the provided V-shaped connecting rod 33, the side baffle 7 can be driven to rotate, and then the side sliding plate 8 can move downward while rotating, thereby increasing the angle between the side baffle 7 and the bed board 2, and then appropriately increasing the width of the bed board 2, so as to facilitate the adjustment of the device according to the body shape changes brought about by the continuous growth of the baby, and improve the practicability of the device.
