[0027] Through the threaded cooperation of the screw rod 7 and the movable plate 8, it is convenient to adjust the movable plate 8 to move upward along the cavity 6, thereby driving the fixed block 9 and the table board 10 to move upward to the outside of the cavity 6. Combined with the action of the damping shaft between the table board 10 and the fixed block 9, it is convenient to adjust the table board 10 to flip inward to a horizontal state for easy use. At the same time, it is convenient to adjust the table board 10 to flip to a vertical state after use and store it inside the cavity 6, realizing the folding and storage of the table board 10, solving the problem in the prior art that when the dining table is not needed, it is necessary to adjust the locking part, pull the rod out of the dining table mounting tube, and then disassemble the dining table. The operation is relatively cumbersome, and the disassembled dining table cannot be stored, making the use of the nursing chair more inconvenient.

[0028] The limiting component includes an extrusion plate 12, an active cavity 11 is opened on the front side of the armrest 5, and the extrusion plate 12 is movably arranged in the active cavity 11, and a plurality of extrusion springs 14 are connected between the rear end of the extrusion plate 12 and the inner wall of the active cavity 11. A through hole is opened on the front side of the inner wall of the active cavity 11, and the through hole passes through the front end of the armrest 5. The front end of the extrusion plate 12 is fixedly connected to the limiting plate 13, and movably cooperates with the through hole. The limiting plate 13 cooperates with the upper surface of the table board 10, and a strip groove 15 passes through one side of the inner wall of the active cavity 11. A shift block 16 is fixed on the outer side of the extrusion plate 12, and movably cooperates with the strip groove 15. Through the elastic action of the extrusion spring 14, it is easy to squeeze the extrusion plate 12 to the front side, and then drive the limiting plate 13 to pass through the through hole and move to the upper side of the table board 10, effectively limiting the table board 10, so that the table board 10 is stable in a horizontal state, ensuring the stability of the table board 10 during use.

[0029] Two rotating shafts are provided on the base 1 for relative rotation. The upper end of the rotating shaft extends into the interior of the cavity 6 and is connected to the lower end of the screw rod 7. An L-shaped support plate 17 is fixed to the bottom of the seat cushion 2. A motor 18 is installed on the inner side of the support plate 17. The output end of the motor 18 is connected to a rotating rod. Pulleys are provided on the rotating rod and the rotating shaft. A transmission belt 19 is provided between the two adjacent pulleys on the left and right to drive the two screw rods 7 to rotate synchronously.

The movable plate 8 slides with the guide rod 20, which effectively limits and guides the movable plate 8, thereby ensuring the stability of the movable plate 8 moving up and down.

[0030] Two rollers 21 are relatively arranged on the rear side of the bottom of the base 1, and two universal wheels 22 with a self-locking structure are relatively installed on the front side of the bottom of the base 1, which facilitates the movement of the nursing chair. A pillow 23 is provided on the backrest 3, and a foot pedal 24 is provided on the lower side of the front surface of the base 1.

[0031] Example:

[0032] In the initial state, the movable plate 8 is at the bottom of the cavity 6, and the table top 10 is in a vertical state, completely stored in the cavity 6, and the vertically upward end surface of the table top 10 is at the same level as the top of the side panel 4;

[0033] When in use, the motor 18 is started by the control switch, and the motor 18 drives the rotating rod to rotate. Under the cooperation of the pulley and the transmission belt 19, the rotating shafts on both sides are driven to rotate synchronously, thereby driving the two screw rods 7 to rotate synchronously;

[0034] The screw rod 7 cooperates with the thread of the movable plate 8, and the movable plate 8 cooperates with the guide rod 20, driving the movable plate 8 to move upward steadily until the movable plate 8 moves up to abut against the top of the inner side of the cavity 6, at which time the fixed block 9 and the table top 10 are completely moved to the outside of the cavity 6;

[0035] Next, move the shift block 16 backward along the strip groove 15 to drive the extrusion plate 12 to move backward and compress the extrusion spring 14 until the limit plate 13 is moved backward to the inside of the active cavity 11;

[0036] At this time, under the action of the damping shaft between the table top 10 and the fixed block 9, the table top 10 is adjusted to flip inward to a horizontal state, so that the downward side of the table top 10 is in contact with the upper surface of the side panel 4;

[0037] Then, the shift block 16 is released, and under the elastic action of the extrusion spring 14, the extrusion plate 12 is pressed forward, thereby driving the limiting plate 13 to pass through the through hole and move to the outside. At this time, the lower surface of the limiting plate 13 contacts the upper surface of the table board 10, effectively limiting the top of the table board 10, ensuring that the table board 10 is stable in a horizontal state, making it convenient for the user of the nursing chair to use;

[0038] After use, according to the above principle, the table top 10 is adjusted in reverse to be flipped to a vertical state, and the motor 18 is driven to rotate in the opposite direction, driving the movable plate 8 to move downward until the table top 10 is completely moved into the cavity 6, thereby realizing the folding and storage of the table top 10, facilitating the use of the table top 10, and solving the problem in the prior art that when the dining table is not needed, it is necessary to adjust the locking part, pull the rod out of the dining table mounting tube, and then disassemble the dining table, which is a cumbersome operation and the disassembled dining table cannot be stored, making the use of the nursing chair more inconvenient.

[0039] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented;

[0040] At the same time, the motor 18 in the present invention is purchased on the market, and those skilled in the art can install it according to the requirements and connect it to the battery and the control switch for use;
