[0028] Reference Figure 1-4 As shown, this embodiment discloses a learning auxiliary chair, including a chair 1 and a cushion block 5. A backrest 4 is provided on one side of the chair 1, and an adjustment device 2 is provided on one side of the backrest 4.
[0029] Reference Figure 1-4As shown, the present embodiment discloses that the adjustment device 2 includes a slide rail 21, the slide rail 21 is fixedly connected to the backrest 4, a sliding block 22 is slidably connected inside the slide rail 21, a clamping block 23 is inserted on one side of the sliding block 22, a plurality of clamping holes 24 are opened on one side of the slide rail 21, the clamping block 23 is clamped with the clamping holes 24 on the surface of the slide rail 21, and the sliding block 22 is fixedly connected to the cushion block 5. When using the learning auxiliary chair, there will be a cushion block 5 at the backrest 4 of the chair to support the user's waist, and then assist the user so that the user can better maintain a sitting posture for learning. When users of different heights use the pad 5 on the surface of the backrest 4, the sliding block 22 can be moved to make the sliding block 22 move inside the slide rail 21, and then the sliding block 22 drives the pad 5 to change its position, and then the pad 5 is adapted to the user's height, and then the clamping block 23 is moved to make the clamping block 23 pass through the sliding block 22 and reach the inside of the clamping hole 24 on the surface of the slide rail 21, and then the position of the sliding block 22 is fixed, and then the position of the pad 5 is fixed after adjustment. By using the adjustment device 2, the position of the pad 5 on the surface of the backrest 4 can be changed, avoiding the situation that the position of the pad 5 at the backrest 4 is fixed and cannot be adapted to users of different heights, thereby improving the adaptability of the learning auxiliary seat.
[0030] Reference Figure 1-4 As shown, this embodiment discloses that one side of the sliding block 22 is fixedly connected with a reinforcing block 25, and the side of the reinforcing block 25 away from the sliding block 22 is fixedly connected with the cushion block 5. By using the reinforcing block 25, the connection strength between the sliding block 22 and the cushion block 5 is improved to avoid the separation of the cushion block 5 from the sliding block 22. The inside of the slide rail 21 is fixedly connected with an arc block 26, and the surface of the arc block 26 is smooth. By using the arc block 26, the friction between the slide rail 21 and the sliding block 22 is reduced, and then the sliding block 22 is made easier to move. One side of the clamping block 23 is fixedly connected with an elastic rope 27, and the side of the elastic rope 27 away from the clamping block 23 is fixedly connected with the sliding block 22. By using the elastic rope 27, the clamping block 23 is connected to the sliding block 22 to avoid the loss of the clamping block 23. One side of the sliding block 22 is fixedly connected with a magnet 28, and one side of the clamping block 23 is fixedly connected with an iron sheet 29, and the iron sheet 29 and the magnet 28 are magnetically attracted. The iron sheet 29 on the surface of the clamping block 23 is adsorbed by the magnet 28 , and then the clamping block 23 is more stably located inside the clamping hole 24 on the surface of the slide rail 21 .
[0031] Reference Figure 1-4As shown, this embodiment discloses that an auxiliary device 3 is provided on one side of the sliding block 22, and the auxiliary device 3 includes a placement block 31, the placement block 31 is fixedly connected to the sliding block 22, and one side of the placement block 31 is rotatably connected to an auxiliary handle 32. When the user moves the sliding block 22 to adjust the position of the cushion block 5, the auxiliary handle 32 on the surface of the placement plate can be used to increase the contact area between the user and the sliding block 22, and then the user can change the position of the sliding block 22 conveniently. By using the auxiliary device 3, the user can move the sliding block 22 more easily, and then the use effect of the adjustment device 2 is improved.
[0032] Reference Figure 1-4 As shown, this embodiment discloses that a limiting block 33 is fixedly connected to one side of the placement block 31, and the size of the limiting block 33 is adapted to the size of the auxiliary handle 32. By using the limiting block 33, the rotation angle of the auxiliary handle 32 is limited, and then the auxiliary handle 32 is conveniently folded, stored and used. A rubber sleeve 34 is fixedly connected to one side of the auxiliary handle 32, and the size of the rubber sleeve 34 is adapted to the size of the auxiliary handle 32. By using the rubber sleeve 34, the friction between the auxiliary handle 32 and the user's hand is increased, and then the auxiliary handle 32 is easier to use.
[0033] Working principle: When using the learning auxiliary seat, there will be a cushion block 5 at the backrest 4 of the seat to support the user's waist and then assist the user so that the user can better maintain a sitting posture for learning. When users of different heights use the pad 5 on the surface of the backrest 4, the sliding block 22 with the reinforcing block 25 can be moved to make the sliding block 22 move inside the slide rail 21 with the arc block 26, and then the sliding block 22 drives the pad 5 to change its position, and then the pad 5 is adapted to the height of the user, and then the clamping block 23 with the elastic rope 27 is moved to make the clamping block 23 pass through the sliding block 22 to reach the inside of the clamping hole 24 on the surface of the slide rail 21, and then the position of the sliding block 22 is fixed, at this time, the iron sheet 29 on the surface of the clamping block 23 is adsorbed by the magnet 28, and then the clamping block 23 is more stably located inside the clamping hole 24 on the surface of the slide rail 21, and then the position of the pad 5 after adjustment is fixed, and by using the adjusting device 2, the position of the pad 5 on the surface of the backrest 4 can be changed, so as to avoid the situation that the pad 5 at the backrest 4 is fixed and cannot be adapted to users of different heights, thereby improving the adaptability of the learning auxiliary seat.
[0034] When the user moves the sliding block 22 to adjust the position of the cushion block 5, the auxiliary handle 32 with the rubber sleeve 34 can be rotated. At this time, the limiting block 33 limits the rotation angle of the auxiliary handle 32, and then one side of the auxiliary handle 32 protrudes from the backrest 4. Then, the user can sit on the chair 1 and lift the auxiliary handle 32 upward, thereby driving the sliding block 22 to move upward, and then it is convenient for the user to change the position of the sliding block 22. By using the auxiliary device 3, the user can more easily move the sliding block 22, thereby improving the use effect of the adjustment device 2.
