[0002] In modern work and study, people sit in the office for a long time, which leads to problems with the lumbar spine. There are more and more patients with cervical spondylosis and lumbar disc herniation, and they are getting younger and younger. Bad sitting posture often causes myopia. The body leans forward, and the waist will be under great pressure after losing the support of the chair back, which greatly hurts the waist. Bending over and hunching over makes the spine arch, which causes a certain amount of pressure on the cervical spine, making it easy to have soreness in the head, shoulders, neck and other parts, and even suffer from cervical spondylosis. Tools for correcting sitting posture are generally divided into seats and cushions.

[0003] In the prior art, the base plate and backrest plate used for correcting sitting posture are inconvenient to adjust the distance parameters, are not flexible enough to use, and the seat cushion is easily displaced, which affects the sitting comfort and leads to problems such as lumbar spine. Therefore, a base plate and backrest plate of a sitting posture correction cushion are needed. Utility Model Content

[0007] Preferably, a second screw groove vertically distributed with the first screw groove is fixedly opened inside the backrest board body, and the second screw groove is located below the first screw groove. The inner wall of the second screw groove is threadedly connected to the backrest board body by providing a second screw rod adapted thereto, a second distance adjustment handle is fixedly installed on one end of the second screw rod, and a lumbar support plate is fixedly installed on the other end of the second screw rod, and a second sponge pad is fixedly installed on the inner wall of the lumbar support plate.

[0008] Preferably, the backrest plate body is connected and fixed to the top of the base plate body by symmetrically distributed support rods.

[0009] Preferably, a fixed square groove is fixedly provided on the top of the base plate body, and a fixed base adapted thereto is movably installed inside the fixed square groove.

[0010] Preferably, a hard sponge cushion matching with the fixed base is fixedly mounted on the top of the fixed base, and a correction limit groove is fixedly opened on the top of the hard sponge cushion.

[0011] Preferably, the backrest board body forms a first correction structure with the base board body through the first screw, the first distance adjustment handle, the neck support plate, the second screw, the second distance adjustment handle and the waist support plate.

[0012] Preferably, the base plate body forms a second correction structure with the backrest plate body through a fixed square groove, a fixed base, a hard sponge cushion and a correction limit groove.

[0013] Beneficial effects achieved by the utility model:

[0014] 1. The first screw is driven to move back and forth inside the first screw groove by rotating the first distance adjustment handle, thereby driving the neck support plate to be telescopically adjusted, so that the neck support plate can be flexibly adjusted according to the user's situation. The second screw is driven to move back and forth inside the second screw groove by rotating the second distance adjustment handle, thereby driving the waist support plate to be telescopically adjusted, so that the waist support plate can be flexibly adjusted according to the user's situation, so that the sitting posture of different users can be corrected, the parameters can be flexibly adjusted, and the actual use effect can be improved;

[0015] 2. The fixed base can be flexibly fixed through the fixed square groove to prevent the user from shifting when sitting for a long time, which will affect the effect of posture correction. The correction limit groove on the hard sponge seat cushion can be used to fix the user's sitting posture to prevent the user from moving, thereby preventing deviations in the correction position and improving the correction effect.
