Detailed Implementation

[0014] 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.

[0015] Example 1 like Figures 1-6 As shown, this utility model provides a technical solution: an adjustable mattress with partial height adjustment, including an adjustable base 1 and a connecting mattress 2. The top of the adjustable base 1 has a groove 101. Folding mattresses 3 are rotatably installed on both sides of the connecting mattress 2. A hinge 31 is fixedly installed on the top of the folding mattress 3, and one end of the hinge 31 is fixedly connected to the top of the connecting mattress 2. A guide rail 32 is fixedly installed on the bottom of the folding mattress 3. Two cranks 4 are rotatably installed on the surface of the adjustable base 1. A two-way screw 41 is fixedly connected to the rear end of the crank 4. A guide plate 5 is provided at the bottom of the folding mattress 3 and is slidably connected to the guide rail 32. A docking groove 501 is provided at the bottom of the guide plate 5. A slot 502 is provided on both sides of the inner wall of the docking groove 501. A connecting plate 6 is provided inside the groove 101. The two-way screw 41 is rotatably installed inside the groove 101. Threaded sleeves 42 are threadedly installed at both ends of the surface of the two-way screw 41. A rotating rod 43 is rotatably installed on the top of the threaded sleeve 42. A support block 44 is rotatably installed on the top of the rotating rod 43.

[0016] In this embodiment, the connecting mattress 2 and the folding mattress 3 are combined and connected by a hinge 31, so that the folding mattress 3 can be flipped up and lifted. Folding mattresses 3 are provided on both sides of the connecting mattress 2, so that multiple parts can be lifted for use. The bidirectional lead screw 41 is threadedly connected to the threaded sleeve 42, so that turning the crank 4 drives the bidirectional lead screw 41 to rotate, which can move the threaded sleeve 42. The two ends of the rotating rod 43 are respectively connected to the threaded sleeve 42 and the support block 44, so that the two ends of the threaded sleeve 42 come closer to each other and push the support block 44 upward, thereby supporting and lifting the folding mattress 3 at the top, making it convenient to lift the folding mattress 3 for back support use.

[0017] Example 2 like Figures 1-6As shown, the shape of the connecting plate 6 matches the shape of the docking groove 501. The bottom of the connecting plate 6 is rotatably connected to the top of the support block 44. A slider 51 is fixedly installed on the top of the guide plate 5. The slider 51 is T-shaped and is slidably installed inside the guide rail 32. A push rod 52 is slidably installed on the side of the guide plate 5. One end of the push rod 52 extends into the slot 502. A storage cavity 601 is opened inside the connecting plate 6. A spring 61 is fixedly installed inside the storage cavity 601. One end of the spring 61 is fixedly connected to a locking block 62. One side of the locking block 62 is a slope surface, and the slope surface of the locking block 62 extends outward to the outside of the connecting plate 6.

[0018] In this embodiment, the sliding connection between the slider 51 and the guide rail 32 allows the guide plate 5 to move horizontally at the bottom of the folding mattress 3. By locking one end of the locking block 62 inside the slot 502, the guide plate 5 and the connecting plate 6 can be connected together. The connecting plate 6 is rotatably connected to the support block 44, so that when the support block 44 rises and lifts the folding mattress 3, it can drive the guide plate 5 to slide. At the same time, the connecting plate 6 will rotate accordingly to avoid the fixed angle causing jamming. The connection between the guide plate 5 and the connecting plate 6 can prevent the folding mattress 3 from flipping when lifted, which will affect its use, and can improve the stability of the mattress. The locking block 62 is connected to the spring 61, and one end of the push rod 52 is set inside the slot 502. Pushing the push rod 52 causes the locking block 62 to retract into the storage cavity 601, which can release the limiting fixation of the connecting plate 6, making it easy to separate the guide plate 5 and the connecting plate 6, thereby making it easy to remove and replace the mattress from the top of the adjustment base 1.

[0019] Working principle: Hinge 31 connects the connecting mattress 2 and the folding mattress 3, allowing the folding mattress 3 to be flipped. By placing the connecting mattress 2 and the folding mattress 3 together on top of the adjusting base 1, the mating groove 501 at the bottom of the guide plate 5 is aligned with the connecting plate 6, so that the guide plate 5 fits onto the surface of the connecting plate 6. The locking block 62 is pressed and moves into the storage cavity 601, compressing the spring 61. When the locking block 62 aligns with the locking groove 502, the locking block 62 rebounds, causing its inclined surface to embed into the locking groove 502, thus connecting the guide plate 5 and the connecting plate 6. When the folding mattress needs to be folded... When the mattress 3 is lifted for use, the crank handle 4 drives the bidirectional lead screw 41 to rotate. The rotating rod 43 lifts the support block 44 and the connecting plate 6 upwards. When the support block 44 rises and lifts the folding mattress 3, it can drive the guide plate 5 to slide, thereby supporting and lifting the folding mattress 3 at the top. This makes it convenient to lift the folding mattress 3 for back support and use. By pushing the push rod 52, the locking block 62 retracts into the storage cavity 601, which can release the limiting fixation of the connecting plate 6, making it convenient to separate the guide plate 5 from the connecting plate 6, thus making it convenient to remove and replace the mattress from the top of the adjustment base 1.
