[0028] like Figure 1-5 As shown, a movable, liftable surgical nursing chair includes a base plate 1. An electric hydraulic cylinder 4 is installed at the upper end of the base plate 1. A seat plate 6 is fixedly connected to the upper end of the electric hydraulic cylinder 4. The left and right sides of the rear end of the seat plate 6 are movably connected to the left and right ends of a rotating rod 11, respectively. The rotating rod 11 is fixedly connected to the lower end of a backrest plate 15. A back massage plate 16 is installed on the backrest plate 15, and several massage holes are opened inside the back massage plate 16. A massage care mechanism 14 is installed at the rear end of the backrest plate 15. Through the cooperation between the massage care mechanism 14 and the back massage plate 16, a massage care effect can be achieved for patients whose backs are resting on the backrest plate 15. The electric hydraulic cylinder 4 can drive the seat plate 6 to move up and down, so that the device can adjust the position and height of the seat plate 6 according to different patients, thereby expanding the applicability of the device and making it convenient for different patients to use.

[0029] Both ends of the rotating rod 11 are fixedly connected to worm gears 10. The two worm gears 10 mesh with the two worms 12 respectively. The lower ends of the two worms 12 are fixedly connected to bevel gears 8 respectively. The two bevel gears 8 mesh with the two bevel gears 7 respectively. The two bevel gears 7 are fixedly connected to one end of the two rotating rods 20 respectively. The other end of the two rotating rods 20 is fixedly connected to the two output shafts of the dual-axis motor 18. The rotation of the output shaft of the dual-axis motor 18 drives the two rotating rods 20 to rotate. Under the action of the bevel gears 8 and 7, the two worms 12 can be driven to rotate. The rotation of the two worms 12, under the action of the two worm gears 10, drives the rotating rod 11 to rotate. This allows for the adjustment of the tilt angle of the backrest 15 during use.

[0030] Furthermore, L-shaped plates 1-9 are movably connected to both worm gears 12, and both L-shaped plates 1-9 are fixedly connected to the lower end of the seat plate 6. The dual-axis motor 1-18 is fixedly connected to the seat plate 6 via a motor frame mounted on it. L-shaped plates 2-20 are movably connected to both rotating rods 2-20, and the upper ends of both L-shaped plates 2-20 are fixedly connected to the seat plate 6. A seat cushion 17 is provided on the upper end of the seat plate 6. Arm-mounted protective frames 13 are provided on both the left and right sides of the upper end of the seat plate 6. Four limiting telescopic sleeves 5 are fixedly connected to the lower end of the seat plate 6, and the lower ends of the four limiting telescopic sleeves 5 are fixedly connected to the base plate 1. Foot pads 3 are provided on the upper end of the base plate 1, and casters 2 are provided at the four corners of the bottom surface of the base plate 1. The L-shaped plates 1-9 provide support for the worm gears 12, the L-shaped plates 2-20 provide support for the rotating rods 2-20, and the limiting telescopic sleeves 5 increase the stability of the seat plate 6 during its up-and-down movement.

[0031] Furthermore, the massage and care mechanism 14 includes a dual-axis motor 149, which is fixedly connected to the backrest plate 15 via another motor frame mounted thereon. The dual-axis motor 149 has two output shafts fixedly connected to two bevel gears 148, which in turn mesh with two bevel gears 147. The two bevel gears 147 are fixedly connected to two rotating rods 1411, each of which has two cams 1412 and four cams 1413 fixedly connected to it. The front ends of 12 overlap with the rear ends of the mounting vertical plate 145. The front end of the mounting vertical plate 145 is provided with several massage blocks 146, and the massage blocks 146 correspond to several massage through holes opened inside the back massage plate 16. Two limiting sliders 144 are fixedly connected to both the upper and lower ends of the mounting vertical plate 145. The four limiting sliders 144 are slidably connected to four fixing rods 143. The front ends of the four fixing rods 143 are fixedly connected to the back plate 15, and the rear ends of the four fixing rods 143 are fixedly connected to two concave plates 141. The front ends of both concave plates 141 are fixedly connected to the back plate 15. Springs 1410 are sleeved on each of the four fixed rods 143. Two support plates 142 are movably connected to each of the two rotating rods 1411. The front ends of the four support plates 142 are fixedly connected to the back plate 15. The rotation of the output shaft of the dual-axis motor 149 drives the two bevel gears 148 to rotate, which in turn, under the action of the two bevel gears 147, achieves the effect of driving the two rotating rods 1411 to rotate. The rotation of the cam 1412, spring 1410, fixing rod 143 and limiting slider 144 can drive the mounting plate 145 to reciprocate in the front and back direction. This can cause the massage blocks 146 mounted on it to repeatedly pass through the massage holes opened on the back massage plate 16, thereby achieving a massage and care effect on the user's back. The interaction between the fixing rod 143 and the limiting slider 144 can limit the movement direction of the mounting plate 145.

[0032] The working principle of this utility model is as follows:

[0033] When using this device for back massage, firstly, the electric hydraulic cylinder 4 is activated to move the seat plate 6 to a suitable height according to the patient's individual needs. Then, the user sits on the seat plate 6 with both feet resting on the rubber pads 3, and rests their back against the back massage plate 16. At this time, the dual-axis motor 149 is activated, driving two bevel gears 148 to rotate. These bevel gears 147 then drive two rotating rods 1411 to rotate. The rotation of these two rotating rods 1411, in conjunction with the cam 1412, spring 1410, fixing rod 143, and limiting slider 144, drives the mounting vertical plate 145 to move forward and backward. The reciprocating motion of the backrest plate 15 causes the massage blocks 146 to repeatedly pass through the massage holes on the back massage plate 16, thereby achieving a massage and care effect on the user's back. When the tilt angle of the backrest plate 15 needs to be adjusted during the use of the device, the dual-axis motor 18 is started to drive the two rotating rods 20 to rotate. Under the action of the bevel gear 8 and bevel gear 7, the two worm gears 12 are driven to rotate. The rotation of the two worm gears 12, under the action of the two worm wheels 10, drives the rotating rod 11 to rotate, thereby achieving the adjustment of the tilt angle of the backrest plate 15 during use.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
