[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The following is a further description of the present invention in combination with the embodiments.

[0022] See also Figures 1 to 5 In one embodiment of the present application, an intramuscular injection chair includes a seat plate 3, a support rod 2, a base 1 and a first backrest plate 5, wherein the seat plate 3 is mounted on the base 1 through the support rod 2, the first backrest plate 5 is arranged on the periphery of the seat plate 3, and further includes a second backrest plate 6, a lifting mechanism and an armrest assembly, the lifting mechanism includes a mounting plate 7, a lifting support plate 8 and a lifting drive assembly, one end of the mounting plate 7 is connected to the first backrest plate 5, and the other end is slidably connected to the second lifting slot 18 of the lifting support plate 8 through a second lifting slider 17, the position of the second lifting slider 17 in the second lifting slot 18 is adjusted by the lifting drive assembly, and the lifting support plate 8 is connected to the support rod 2;

[0023] The second backrest plate 6 is arranged on one side of the first backrest plate 5, and one end of the second backrest plate 6 is slidably connected to the transverse guide rail 11 provided on the first backrest plate 5 through a transverse slider 10, and the other end of the second backrest plate 6 is connected to the armrest assembly; the armrest assembly includes an armrest 4 and a first lifting slider 12, one end of the armrest 4 is rotatably connected to the first lifting slider 12 through a connecting shaft 22, and the connecting shaft 22 is provided with a matching block 23, and the first lifting slider 12 is provided with a stop block 24 for limiting the matching block 23, so that when the armrest 4 is swung to be parallel to the ground, the matching block 23 is supported on the stop block 24, thereby ensuring the supporting function of the armrest 4 as an armrest; the first lifting slider 12 is slidably connected to the first lifting slot 14 provided on the second backrest plate 6, and the first lifting slot 14 is provided with a height adjustment component for adjusting the position of the first lifting slider 12.

[0024] In this embodiment, two stop blocks 24 are provided: one for supporting the armrest 4 in the horizontal position, and the other for supporting the armrest 4 in the stowed position. It is important to note that there is an angle between the horizontal position and the stowed position, and the stowed position of the armrest 4 is used to avoid interfering with medical personnel administering injections. To ensure the stability of the armrest 4 in different positions, the stop blocks 24 are magnetic, and the mating blocks 23 are magnets. These mating blocks 23 and the stop blocks 24 magnetically engage. When the armrest 4 swings to a position perpendicular to the ground, the mating blocks 23 magnetically attract the stop blocks 24, ensuring the stability of the armrest 4 in the stowed position.

[0025] In this embodiment, the height adjustment assembly includes a first screw rod 13 and a first motor 16. The first motor 16 is installed on the second backrest plate 6. The output end of the first motor 16 is connected to the first screw rod 13. The first screw rod 13 passes through the first lifting slider 12 and is rotatably connected to the second backrest plate 6. The first screw rod 13 is threadedly connected to the first lifting slider 12.

[0026] In order to facilitate the user to adjust the height of the armrest 4 according to his or her own comfort, an adjustment button 15 for adjusting the height of the armrest 4 is provided on the second backrest plate 6. When in use, the up and down keys of the adjustment button 15 are used to control the forward and reverse rotation of the first motor 16, thereby driving the first screw rod 13 to rise or fall in the first lifting slot 14, thereby achieving the function of adjusting the height of the armrest 4.

[0027] In this embodiment, the lifting drive assembly includes a second motor 20 and a second screw rod 19, one end of the second screw rod 19 is connected to the output end of the second motor 20, and the other end of the second screw rod 19 passes through the second lifting slider 17 and is rotatably connected to the lifting support plate 8. The second screw rod 19 is also threadedly connected to the second lifting slider 17. The second motor 20 drives the second screw rod 19 to rotate forward and reverse, thereby driving the second lifting slider 17 to rise and fall in the second lifting slot 18, and then driving the mounting plate 7 to rise and fall, so that the first backrest plate 5 can provide back support and can be stored under the seat plate 3, which is more conducive to intramuscular injection.

[0028] In this embodiment, the support rod 2 is a telescopic structure, and the lifting support plate 8 is connected to the support rod 2 through the connecting plate 9, wherein the lifting support plate 8 is slidingly connected to the third lifting slot 21 of the connecting plate 9, and the connecting plate 9 is fixedly connected to the support rod 2, so that when the length of the support rod 2 is adjusted, the stability of the position of the first backrest plate 5 can be ensured.
