[0024] The stabilizing mechanism 3 includes a slider 301, a slide bar 302, a movable plate 303, a support block 304 and a support plate 305. The outer wall of the slider 301 is slidably connected to the base 1. The slider 301 slides inside the base 1. The slider 301 will not be separated from the base 1. The slider 301 is fixedly connected to one end of the slide bar 302. The slider 301 and the slide bar 302 slide together. The outer wall of the slide bar 302 is slidably connected to the base 1. The other end of the slide bar 302 is fixedly connected to the movable plate 303. The movable plate 303 moves together with the slide bar 302. The movable plate 303 always fits the ground when moving.

[0025] The upper surface of the movable plate 303 is fixedly connected with a support block 304, and the movable plate 303 drives the support block 304 to move. The outer wall clearance of the lower end of the support plate 305 of the support block 304 is matched, and the support plate 305 can be inserted into the groove set in the support block 304. The upper end of the support plate 305 is fixedly connected with the seat plate 7, and the seat plate 7 moves with the support plate 305. The lower end of the support plate 305 is fixedly connected with the first magnet block 12, and the interior of the support block 304 is fixedly connected with the second magnet block 13. The magnetic poles of the first magnet block 12 and the second magnet block 13 are opposite, and the two attract each other.

When the user sits on the seat plate 7, the support plate 305, the support block 304 and the movable plate 303 support the seat plate 7. The support plate 305 transmits the force vertically downward to the support block 304, so that the support effect of the support block 304 on the support plate 305 is more stable, and then the support of the seat plate 7 is more stable. When in use, the auditorium chair has a better stability effect.

[0027] The guide mechanism 4 includes a sleeve 401, a bent rod 402 and a spring 403. The end of the sleeve 401 is fixedly connected to the back plate 2. The inside of the sleeve 401 is slidably connected to the bent rod 402. The bent rod 402 slides inside the sleeve 401. The end of the bent rod 402 is fixedly connected to the seat plate 7. The bent rod 402 moves with the seat plate 7. A spring 403 is arranged inside the sleeve 401. The model of the spring 403 is selected according to actual use requirements to meet the work requirements. The two ends of the spring 403 are fixedly connected to the sleeve 401 and the bent rod 402 respectively. The spring 403 can drive the bent rod 402 to slide under the action of elasticity.

[0028] The seat plate 7 drives the bent rod 402 to move, and the bent rod 402 slides inside the sleeve 401. The bent rod 402 compresses the spring 403. The bent rod 402 and the sleeve 401 guide the rotation of the seat plate 7, making the movement of the seat plate 7 more stable. At the same time, the spring 403 can drive the sliding rod 402 to slide under the elastic action, so that the seat plate 7 can be restored to an oblique upward state when not in use, avoiding the seat plate 7 from occupying space. The bent rod 402 is slidably connected to the sleeve 401, and the seat plate 7 is not prone to jamming when rotating.

[0029] Working principle:

[0031] Seat plate rotation stage:

[0032] The seat plate 7 is in an oblique upward state when not in use. When the auditorium chair is needed, the seat plate 7 is rotated, and the seat plate 7 drives the bent rod 402 to move. The bent rod 402 slides inside the sleeve 401, and the bent rod 402 compresses the spring 403. The bent rod 402 and the sleeve 401 guide the rotation of the seat plate 7, making the movement of the seat plate 7 more stable. At the same time, the spring 403 can drive the sliding rod 402 to slide under the elastic action, so that the seat plate 7 can be restored to an oblique upward state when not in use, avoiding the seat plate 7 from occupying space. The bent rod 402 is slidably connected to the sleeve 401, and the seat plate 7 is not prone to jamming when rotating;

[0033] Auditorium chair stable stage:

[0034] The support plate 305 is inserted into the groove provided in the support block 304, and when the user sits on the top of the seat plate 7, the support plate 305, the support block 304 and the movable plate 303 support the seat plate 7, and the support plate 305 transmits the force vertically downward to the support block 304, so that the support effect of the support block 304 on the support plate 305 is more stable, and thus the support of the seat plate 7 is more stable, so that the auditorium chair has a better stability when in use;

[0035] When the end of the support plate 305 is inserted into the interior of the support block 304, the first magnet block 12 and the second magnet block 13 attract each other to prevent the seat plate 7 from rotating under the elastic action of the spring 403 when the auditorium chair is in use. When not in use, the seat plate 7 is slightly lifted upward to separate the first magnet block 12 and the second magnet block 13, and the spring 403 restores the seat plate 7 to an oblique upward position under the elastic action of the spring 403.
