DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides an embodiment: a conveniently adjustable auditorium chair, comprising a base 1, a cushion 3, a support seat 4 and a backrest 7. Servo motors 2 are installed on both sides of the bottom end of the base 1. The output shaft end of the servo motor 2 is installed with a threaded rod 201. The top of the threaded rod 201 is rotatably connected to a limiting rod 202. The outer thread of the threaded rod 201 is connected to a threaded cylinder 203. The top of the threaded cylinder 203 is fixedly connected to the cushion 3. Two groups of servo motors 2 are installed inside the base 1 and can be used alternately. The servo motor 2 can be started to drive the threaded rod 201 to rotate inside the threaded cylinder 203. At this time, the threaded cylinder 203 can push the cushion 3 to lift. At the same time, a limiting rod 202 is arranged on the top of the threaded rod 201 and can slide inside the threaded cylinder 203, thereby playing an auxiliary limiting work for the threaded rod 201 to prevent the threaded rod 201 from escaping from the inside of the threaded cylinder 203.

[0022] The two sides of the base 1 are fixedly connected with a support base 4, the top of the support base 4 is fixedly connected with a hand rest 401, and a control button is installed on one side of the top of the hand rest 401 to start the servo motor 2, wherein starting the motor by the control button is an existing technology;

[0023] A card slot 402 is provided in the middle of one side of the support seat 4, and the hand rest 401 can be used to facilitate the user to hold the hand. At the same time, when the card block 6 on one side of the support seat 4 of the auditorium chair is inserted into the card slot 402 on the support seat 4 of the same auditorium chair, and the insert block 503 in the card slot 402 is inserted into the slot 601 on the card block 6, the connection and assembly of the same auditorium chair can be completed;

[0024] A pull rod 5 is slidably connected to one side of the outside of the support seat 4, a movable plate 501 is fixedly connected to one side of the pull rod 5, a spring 502 is fixedly connected to one side of the movable plate 501, and an insert block 503 is fixedly connected to one side of the movable plate 501. When the pull rod 5 on one side of the support seat 4 is pulled, the pull rod 5 can squeeze the spring 502 on one side through the movable plate 501, and the movable plate 501 can drive the insert block 503 to be retracted into the inside of the support seat 4. When the pull rod 5 is released, the movable plate 501 can push the insert block 503 to reset due to the reaction force of the squeezed spring 502.

[0025] A clamping block 6 is fixedly connected to the middle position of one side of the support seat 4, and a slot 601 is provided inside one side of the clamping block 6. The position of the clamping block 6 is aligned with the position of the hand support 401 on the support seat 4, so as to facilitate the assembly of similar auditorium chairs;

[0026] A backrest 7 is installed on one side of the base 1, a support leg 8 is fixedly connected to the bottom end of the support seat 4, and a reinforcement rod 801 is fixedly connected to one side of the support leg 8. The backrest 7 can be used for the user to lean on the back, and the support leg 8 and the reinforcement rod 801 can reinforce the auditorium chair as a whole.

[0027] When the embodiment of the present application is in use: the user can sit on the cushion 3 at the top of the base 1 and lean back on the backrest 7. By pressing the control button at the top of the support seat 4, the support seat 4 can control the servo motor 2 inside the base 1 to start. At this time, the servo motor 2 can drive the threaded rod 201 to rotate inside the threaded cylinder 203, and the threaded cylinder 203 can push the cushion 3 to lift, so that the cushion 3 can drive the user to adjust to a suitable height for use. At the same time, the two sides of the auditorium chair are respectively provided with a card slot 402 and a card block 6. By pulling the pull rod 5 on the support seat 4, the pull rod 5 can squeeze the spring 502 through the movable plate 501, and the movable plate 501 can pull the plug block 503 into the interior of the support seat 4. At this time, the card block 6 on one side of the auditorium chair is inserted into the card slot 402 on the side of the same auditorium chair, and the pull rod 5 is released. Due to the reaction force of the spring 502 being squeezed, the plug block 503 can be pushed through the movable plate 501 to insert into the slot 601 on the card block 6, thereby completing the assembly work between similar auditorium chairs.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model.
