[0002] With the deepening of medical research, people have gained a clearer understanding of the anatomical structure, biomechanical characteristics, and pathogenesis of lumbar diseases. Studies have found that maintaining poor posture for extended periods, such as slouching or hunching, alters the normal stress distribution on the lumbar spine, leading to increased pressure on the intervertebral discs, excessive strain on the lumbar muscles, and consequently, various lumbar diseases. Based on these research findings, researchers realized the need to design a product that could help maintain the normal physiological posture of the lumbar spine and reduce lumbar pressure, thus giving rise to the lumbar support cushion.
[0003] However, existing adjustable lumbar support cushions have the following drawbacks:

[0018] (III) Beneficial Effects
[0019] This utility model provides an adjustable lumbar support cushion, which has the following beneficial effects:
[0020] 1. This adjustable lumbar support cushion, through the arrangement of a threaded rod, a slider, a rotating block, and a connecting rod, allows the operator to adjust the angle of the cushion by first rotating the threaded rod, which moves the slider connected to it, causing the rotating block and connecting rod to change angles. This, in turn, causes the cushion to change angles via the connecting plate, thus improving the flexibility of the device.
[0021] 2. This adjustable lumbar support cushion, through the design of sliding blocks, springs, locking rods, push rods, and round holes, allows staff to disassemble the cushion by pushing two push rods in opposite directions. This causes the sliding blocks to move the locking rods, while simultaneously compressing the springs. Once the locking rods are fully moved outside the round holes, the cushion can be disassembled and cleaned, effectively preventing sweat and bacteria from adhering to its surface and ensuring optimal use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0028] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable lumbar support cushion, including a base 1, a connecting plate 2 rotatably connected to the top of the base 1, a cushion 3 movably inserted into one side of the connecting plate 2, an adjustment component 4 between the connecting plate 2 and the base 1, and a disassembly component 5 between the connecting plate 2 and the cushion 3.
[0029] The adjustment assembly 4 includes a slide groove on the top of the base 1. A threaded rod 401 is rotatably connected to the inner wall of the slide groove. One end of the threaded rod 401 extends to the outside of the base 1. A slider 402 is threadedly sleeved on the surface of the threaded rod 401. A rotating block 403 is hinged to the opposite side of the slider 402 and the connecting plate 2. A connecting rod 404 is fixedly connected between the two rotating blocks 403. With the arrangement of the threaded rod 401, slider 402, rotating block 403 and connecting rod 404, when the operator adjusts the angle of the cushion 3, he first rotates the threaded rod 401, which drives the slider 402 threadedly connected to it to move, causing the rotating block 403 and the connecting rod 404 to change angle. This, in turn, causes the cushion 3 to change angle through the connecting plate 2, improving the flexibility of the device.
[0030] The disassembly assembly 5 includes a cavity inside the connecting plate 2. A sliding block 501 is slidably connected to the inner wall of the cavity. A spring 502 is connected between the sliding block 501 and the inner wall of the cavity. A locking rod 503 is fixedly connected to one side of the sliding block 501. A push rod 504 is fixedly connected to the surface of the sliding block 501. A round hole 505 is opened on the surface of the cushion 3. One end of the locking rod 503 extends into the round hole 505. Through the arrangement of the sliding block 501, spring 502, locking rod 503, push rod 504 and round hole 505, when the staff disassembles the cushion 3, they push the two push rods 504 to move towards each other, so that the sliding block 501 drives the locking rod 503 to move, while squeezing the spring 502. When the locking rod 503 has completely moved to the outside of the round hole 505, the cushion 3 can be disassembled and cleaned, effectively preventing sweat and bacteria from adhering to its surface and ensuring the user experience.
[0031] One end of the threaded rod 401 is fixedly connected to a turntable 6. The turntable 6 facilitates the rotation of the threaded rod 401. The turntable 6 is circular in shape.
[0032] An anti-slip pad 7 is fixedly connected to the bottom of the base 1. The stability of the device is improved by the anti-slip pad 7, which is made of rubber.
[0033] A limiting rod 8 is movably inserted into one side of the sliding block 501. The limiting rod 8 makes the sliding block 501 more stable when moving. One end of the limiting rod 8 is fixedly connected to the inner wall of the cavity.
[0034] One end of the push rod 504 extends to the outside of the connecting plate 2, and a fixing block 9 is fixedly connected to one end of the push rod 504. The fixing block 9 facilitates pushing the push rod 504.
[0035] A rectangular groove is provided on one side of the connecting plate 2. The rectangular groove makes it difficult for the push rod 504 to shake when it moves, and the push rod 504 slides inside the rectangular groove.
[0036] In this invention, the working steps of the device are as follows:
[0037] First step: When adjusting the angle of the cushion 3, the staff first rotates the threaded rod 401, which drives the slider 402 connected to it to move, causing the rotating block 403 and the connecting rod 404 to change their angle, thereby driving the cushion 3 to change its angle through the connecting plate 2, which improves the flexibility of the device.
[0038] The second step: When the staff disassembles the cushion 3, they push the two push rods 504 to move towards each other, so that they drive the locking rod 503 to move through the sliding block 501. At the same time, the spring 502 is squeezed. When the locking rod 503 has moved completely to the outside of the round hole 505, the cushion 3 can be disassembled and cleaned. This effectively prevents sweat and bacteria from adhering to its surface and ensures the effect of use for the staff.
