[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 5 A sitting posture auxiliary cushion comprises a mounting plate 1, which is vertically mounted on a seat through a mounting assembly, and further comprises: a first back plate 2, a second back plate 3 and a third back plate 4, which are sequentially mounted on the mounting plate 1 from bottom to top; the first back plate 2 is fixedly connected to the mounting plate 1, and the second back plate 3 and the third back plate 4 are respectively slidably connected to the mounting plate 1; through grooves are provided on adjacent sides of the first back plate 2, the second back plate 3 and the third back plate 4, and connecting rods 7 are slidably connected in every two adjacent through grooves, and elastic ropes 8 are fixedly connected in the through grooves, and the elastic ropes 8 are fixedly connected to the adjacent connecting rods 7; a T-shaped slide groove 401 is provided at the upper end of the third back plate 4; a T-shaped slide plate 402 is symmetrically slidably connected in the T-shaped slide groove 401; an L-shaped plate 405 is mounted on the T-shaped slide plate 402.

[0023] The mounting assembly includes a mounting block 101, a first screw rod 102, a clamping plate 103 and a guide rod 104. The mounting block 101 is fixedly connected at the four corners of the mounting plate 1, the first screw rod 102 is rotatably connected to the side of the mounting block 101 away from the first support plate 2, the clamping plate 103 is threadedly connected to the first screw rod 102, the guide rod 104 is fixedly connected to the side of the mounting block 101 close to the first screw rod 102, and the clamping plate 103 is slidably connected to the guide rod 104.

[0024] A T-shaped slot 105 is symmetrically provided on one side of the mounting plate 1 close to the second support plate 3 . T-shaped bars 9 are symmetrically fixedly connected to one side of the second support plate 3 and the third support plate 4 close to the mounting plate 1 . The T-shaped bars 9 are slidably connected in adjacent T-shaped slots 105 .

[0025] In order to improve the user's sitting posture and avoid diseases such as spinal disease and hunchback, when the user sits on the chair to study or work, the mounting plate 1 is first placed vertically on the chair, and the mounting plate 1 is made to fit against the backrest of the chair. Then the first screw 102 can be rotated, so that the first screw 102 drives the clamping plate 103 to one side of the mounting plate 1 with the cooperation of the guide rod 104, until the clamping plate 103, the mounting plate 1 and the backrest of the chair are tightly fitted, thereby completing the installation operation of the cushion, and then the user can sit on the chair. , and buttocks are pressed against the first backrest board 2, so that the back is in contact with the first backrest board 2, the second backrest board 3 and the third backrest board 4, and then the user can lift the L-shaped board 405 upwards, and then the second backrest board 3 and the third backrest board 4 will move upwards under the pull of the L-shaped board 405, so that the first backrest board 2, the second backrest board 3 and the third backrest board 4 can be fully in contact with the back of the user, and when the L-shaped board 405 is higher than the user's shoulders, the L-shaped board 405 can be lowered to the user's shoulders, and then the L-shaped board 405 can be elastically moved. Under the action of the force rope 8, it is tightly attached to the user's shoulder, so that the user's back can always be restricted in a relatively straight state, avoiding the user's back from bending forward involuntarily during study or work, and effectively improving the effect of assisting the correction of the user's sitting posture. By making the T-shaped slide plate 402 slidably connected to the T-shaped slide groove 401 of the third backrest plate 4, the distance between the two L-shaped plates 405 can be adjusted accordingly according to the user's shoulder width, thereby further improving the applicability of the back cushion. By installing the plate 1 and the first backrest plate 2. The coordinated use of the second backrest board 3, the third backrest board 4, the T-shaped slide groove 401, the T-shaped slide plate 402, the L-shaped plate 405, the through groove, the connecting rod 7, the elastic rope 8, etc., can not only make the back cushion suitable for users of different body shapes, but also effectively improve the applicability of the back cushion. When the user sits on the chair to study or work, the user's back can always be restricted to a relatively straight state, avoiding the user's back from involuntarily bending or leaning forward during the process of studying or working, and effectively improving the effect of assisting in correcting the user's sitting posture.

[0026] Embodiment 2:

[0027] Reference Figure 1-Figure 5, a sitting posture auxiliary cushion, which is basically the same as embodiment 1, and further comprises: a T-shaped slide plate 402 is rotatably connected to a second screw rod 403 on a side away from the mounting plate 1, an adjustment plate 404 is threadedly connected to the second screw rod 403, and an L-shaped plate 405 is fixedly connected to the adjustment plate 404. Before the user uses the cushion, the second screw rod 403 is first rotated to allow the second screw rod 403 to adjust the distance between the L-shaped plate 405 and the third support plate 4 through the adjustment plate 404, so that the L-shaped plate 405 can be flexibly adjusted according to the thickness between the front and back of the user's shoulders, so that the L-shaped plate 405 can be better stuck on the user's shoulders, thereby further improving the applicability of the cushion and facilitating better assistance to the user in correcting the sitting posture and preventing the user from leaning forward.

[0028] The first backrest plate 2, the second backrest plate 3 and the third backrest plate 4 are respectively connected to a back cushion 5 on the side away from the mounting plate 1, and the L-shaped plate 405 is connected to a shoulder pad 406. Through the arrangement of the back cushion 5 and the shoulder pad 406, when the user uses the cushions to assist in correcting the sitting posture, the comfort of the user sitting on the seat for a long time can be improved, and the first backrest plate 2, the second backrest plate 3, the third backrest plate 4 and the L-shaped plate 405 can be avoided to be too hard, thereby preventing the user from feeling uncomfortable.

[0029] The back cushion 5 is detachably connected to the first back plate 2, the second back plate 3 and the third back plate 4 respectively via the first Velcro 6, and the shoulder pad 406 is detachably connected to the L-shaped plate 405 via the second Velcro 407. By making the back cushion 5 detachably connected to the first back plate 2, the second back plate 3 and the third back plate 4, and making the shoulder pad 406 detachably connected to the L-shaped plate 405, it is not only convenient to replace different back cushions 5 and shoulder pads 406 according to the needs of different users, but also the back cushion 5 and the shoulder pad 406 can be disassembled and cleaned, which effectively improves the flexibility of the cushion.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
