[0002] Baby furniture beds are core facilities for infant care. Traditional baby beds generally adopt a fixed-size structure and are only suitable for infants of younger ages. They have problems such as short usage cycle, low space utilization and single function. As parenting concepts develop towards refinement, the market demand for long-term adaptable baby beds is becoming increasingly urgent, requiring the bed to be able to dynamically adjust according to changes in the baby's height and mobility.

[0003] After searching, the patent document with announcement number CN218246530U discloses a size-adjustable baby crib, comprising a bed board body, with extension bed board devices provided on both sides of the outer surface of the bed board body, an arc-shaped support provided at the bottom of the outer surface of the bed board body, and the extension bed board device comprising two extension boards, the outer surface tops of the two extension boards being fixedly connected to bed rails. The size-adjustable baby crib is provided with an extension bed board device. Under the action of the extension board, the extension board can cooperate with the rectangular groove and dovetail slider on the inner wall of the bed board body, so that the extension board can be pulled out from the inner wall of the bed board body or stored in the inner wall of the bed board body, thereby making the size of the bed board body adjustable, thereby being suitable for babies of different body shapes, and thereby preventing babies of different body shapes from feeling embarrassed because the bed board body is too small, thereby improving the baby's sleeping experience.

[0024] Third: The present invention provides multiple support sleeves and piston support columns between the base and the bed board. When there is no baby in it, the bed board can be supported to a certain extent by the action of the return spring. When the baby is put in, it can play a certain buffering role in the downward movement of the bed board, thereby improving the comfort of the baby. In addition, a certain locking effect can be achieved by setting the ventilation pipe and the shut-off valve. When the bed board needs to be moved, the shut-off valve is opened and the piston support column can be moved by the action of the return spring. When locking is required, the shut-off valve is closed to keep the pressure inside the support sleeve unchanged, which will cause the piston support column to be unable to continue moving, thereby achieving the locking effect of the bed board.

[0037] The present invention provides an extendable baby furniture bed that can be adjusted according to the baby's body growth through improvement. The technical solution of the present invention is:

[0038] like Figures 1 to 8 As shown, an embodiment of the present invention provides an extendable baby furniture bed that can be adjusted according to the growth of the baby's body shape, including a base 1 and a bed board 2. The bed board 2 is arranged on the upper part of the base 1, and an arc-shaped protective pad 24 is fixedly installed on the surface of the bed board 2. A plurality of self-locking universal wheels 6 are fixedly installed on the bottom of the base 1, and two pairs of limiting columns 10 are symmetrically fixedly installed on the surface of the base 1. It also includes a protective component, an adjustment component and a support component.

The protective component, adjustment component and support component can effectively achieve a stable adjustment effect on the device, so as to adapt to the body shape changes brought about by the growth of the baby, thereby improving the practicality of the device.

[0039] The protective component is arranged between the limiting column 10 and the bed board 2.

[0040] The protective component includes a long protective rail 17 slidably installed on one side of the limiting column 10, and a pair of short protective rails 18 are slidably installed on both sides of the long protective rails 17. The long protective rails 17 and the short protective rails 18 are set to provide protection for the baby, thereby preventing the baby from falling.

[0041] Adjustment component, the adjustment component is arranged on the bed board 2.

[0042] The adjustment component includes an extension plate 25 slidably installed at both ends of the bed board 2. Both ends of the bed board 2 are provided with sliding grooves adapted to the extension plates 25. Side baffles 7 are installed on both sides of the bed board 2 through hinge rotation. A side slide 8 is slidably installed inside each side baffle 7. A rubber protective plate 9 is fixedly installed between the side slide 8 and the side baffle 7. A two-way threaded rod 27 is installed inside the bed board 2 for rotation. The two ends of the two-way threaded rod 27 are threadedly connected to the extension plate 25. By setting the two-way threaded rod 27, the extension plate 25 can be moved, thereby widening the length of the bed surface. The side baffles 7 and side slides 8 can appropriately increase the width of the bed surface by changing their rotation angle, so that the device can better adapt to the changes brought about by the growth of the baby's body shape, thereby improving the practicality of the device.

[0043] The support assembly is arranged between the base 1 and the bed board 2.

[0044] The support assembly includes multiple support sleeves 3 fixedly installed on the surface of the base 1, and a piston support column 4 is slidably installed in the vertical direction inside each support sleeve 3. A reset spring 5 is fixedly connected between the bottom of the piston support column 4 and the inner bottom of the support sleeve 3.

The support sleeves 3 and piston support columns 4 can achieve a supporting effect on the bed board 2, and the reset spring 5 can ensure that the bed board 2 can achieve an automatic reset effect.

[0045] Furthermore, a plurality of connecting grooves 20 are equidistantly provided on both sides of the long guardrail 17, and a plurality of connecting tubes 21 are symmetrically fixedly installed on one side of the short guardrail 18 close to the long guardrail 17. Each connecting tube 21 slides in cooperation with the corresponding connecting groove 20. By setting up a plurality of connecting tubes 21, it is ensured that the long guardrail 17 can stably move with the short guardrail 18 when moving, thereby realizing the overall movement of the protective assembly, thereby ensuring that the protective assembly can work normally.

[0046] Furthermore, a connecting spring 22 is fixedly installed between the connecting tube 21 and the connecting groove 20, and a rubber protective sleeve 23 is fixedly installed between the short guardrail 18 and the long guardrail 17. The setting of the connecting spring 22 can have a certain pulling effect on the short guardrail 18, thereby ensuring the stability of the movement of the short guardrail 18, and the setting of the rubber protective sleeve 23 can have a protective effect on the gaps between multiple connecting tubes 21, thereby improving the safety of the use of the device.

[0047] Furthermore, each limiting column 10 is provided with a limiting slide groove 11 and an installation groove 12, and a pair of limiting sliders 14 are fixedly installed on one side of the long guardrail 17 close to the limiting column 10. The limiting sliders 14 slide in cooperation with the limiting slide groove 11. The setting of the limiting slide groove 11 and the limiting slider 14 can improve the stability of the movement of the long guardrail 17.

[0048] Furthermore, a fixed pulley 13 is fixedly installed on the inner top of the installation groove 12, and a cable 16 is slidably installed on the fixed pulley 13. A plurality of L-shaped connecting rods 15 are fixedly installed on the bottom of the bed board 2, and the two ends of the cable 16 are fixedly connected to the long guardrail 17 and the L-shaped connecting rod 15 respectively. Through the set fixed pulley 13 and cable 16, the bed board 2 and the guardrail can be linked, so that the bed board 2 can move downward and the protective component can be automatically moved upward at the same time. Moreover, as the weight of the baby grows, the upward movement distance of the protective component also becomes larger, thereby facilitating better protection for the baby.

[0049] Furthermore, a hexagonal mounting block 34 is fixedly installed at one end of the bidirectional threaded rod 27, and a pair of adjusting slots 2 31 are symmetrically opened at the bottom of the bed board 2. An adjusting screw 29 is rotatably installed inside each adjusting slot 2 31. A driving bevel gear 28 is fixedly installed in the middle of the bidirectional threaded rod 27, and a driven bevel gear 30 is fixedly installed near the end of the adjusting screw 29. The driving bevel gear 28 is meshed with the driven bevel gear 30. The existing external hexagonal wrench can easily rotate the bidirectional threaded rod 27 through the hexagonal mounting block 34, and then the bevel gear transmission can drive the pair of adjusting screws 29 to rotate, thereby achieving the transmission effect and realizing the normal operation of the adjustment component.

[0050] Furthermore, the two ends of the bidirectional threaded rod 27 are threadedly connected to the extension plate 25, and a connecting slider 32 is threadedly connected to the adjusting screw 29. The connecting slider 32 slides in cooperation with the adjusting slot 2 31, and a pair of V-shaped connecting rods 33 are fixedly installed between the bottom of the connecting slider 32 and the side baffle 7 through a movable shaft. By utilizing the provided connecting slider 32, the V-shaped connecting rod 33 can realize the rotation effect of the side baffle 7, and then increase the inclination angle of the side slide 8, thereby appropriately widening the width of the bed surface, thereby improving the comfort of using the device.

[0051] Furthermore, a pair of adjustment slots 35 and 19 are respectively provided on the inner sides of the long guardrail 17 and the short guardrail 18. A pair of protrusions 26 are fixedly installed on the end of the extension plate 25. The protrusions 26 slide in cooperation with the adjustment slots 19. A connecting block 39 is slidably installed inside the adjustment slot 35. The connecting block 39 and the side slide 8 are connected to each other through a movable shaft. The provided adjustment slots 19 and 35 can further limit and stabilize the movement of the side slide 8 and the extension plate 25, thereby ensuring the stability of the adjustment process.

[0052] Furthermore, a ventilation pipe 36 is fixedly connected between each two adjacent support sleeves 3, and a T-shaped connecting pipe 37 is fixedly connected between a pair of ventilation pipes 36. A shut-off valve 38 is fixedly installed at the end of the T-shaped connecting pipe 37. The ventilation pipe 36 and the T-shaped connecting pipe 37 are provided to effectively control the air pressure inside the support sleeve 3. When the shut-off valve 38 is opened, the piston support column 4 can move normally under the action of the reset spring 5. When the shut-off valve 38 is closed, it can ensure that the internal air pressure will not change, thereby achieving a locking effect on the piston support column 4, and then achieving a fixing effect on the bed board 2.

[0053] The specific working principle is as follows: first, open the shut-off valve 38 and put the baby on the bed board 2. Under the action of the baby's own gravity, the bed board 2 can be moved downward, and as the bed board 2 moves downward, the protective component can be moved upward through the cable 16 and the fixed pulley 13, thereby improving the protective effect and avoiding the risk of the baby falling, thereby improving the protection effect for the baby. After the bed board 2 moves down to a certain position, close the shut-off valve 38, and by controlling the internal air pressure of the support sleeve 3 to remain unchanged, the piston support column 4 is locked, thereby achieving a fixing effect on the bed board 2, ensuring the stability of the baby on the bed board 2 during the flipping process. When the device needs to be adjusted, it is adjusted through the external The hexagonal wrench and the hexagonal mounting block 34 can easily rotate the two-way threaded rod 27, thereby moving the extension plate 25 and widening the length of the bed board 2. The bevel gear transmission is then used to rotate the two-way threaded rod 27 and the adjusting screw 29, thereby moving the connecting slider 32. The V-shaped connecting rod 33 can be used to rotate the side baffle 7, thereby rotating the side slide 8 and moving it downward, thereby increasing the angle between the side baffle 7 and the bed board 2, thereby appropriately increasing the width of the bed board 2, so that the device can be adjusted according to the changes in body shape brought about by the continuous growth of the baby, thereby improving the practicality of the device.

[0054] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
