[0026] Example 1

[0027] like Figure 1 , Figure 3 and Figure 4As shown, the electrically adjustable lumbar support device for a blood collection chair proposed in this utility model includes a base 1 and a massage mechanism fixed to the inner wall of the base 1. The massage mechanism includes multiple pneumatic rods 15 penetrating the base 1. One end of each pneumatic rod 15 is fixedly connected to a massage head 16, and the end of each pneumatic rod 15 away from the massage head 16 is fixedly connected to an adjustment mechanism. The adjustment mechanism includes a gas distribution pipe 18 fixed to one side of the multiple pneumatic rods 15. The side of each gas distribution pipe 18 away from the pneumatic rods 15 is fixedly connected to a transmission air pipe 17. The top end of each transmission air pipe 17 is fixedly connected to an air transmission pipe 19, and one end of the air transmission pipe 19 is fixedly connected to an air pump 20. A control box 21 is fixedly connected to the end of the air pump 20 away from the air transmission pipe 19. An operating lever 22 is fixedly connected to the outer wall of the control box 21 away from the air pump 20. A fixing bracket 10 is fixedly connected to one side of the outer wall of the control box 21. The fixing bracket 10 is fixed to one side of the base 1. After the device is powered on, the air pump 20 is operated through the ECU-type control box 21. The air pump 20 transmits compressed air into the air transmission pipe 19. The compressed air is transmitted into multiple pneumatic rods 15 through the air transmission pipe 19. The pneumatic rods 15 drive the massage head 16 fixedly connected to one end to push the textile layer 6 to adjust the thickness of the backrest, thereby adjusting the backrest.

[0028] In addition, such as Figure 1 and Figure 2 As shown, a connecting box 2 is fixedly connected to one side of the outer wall of the base 1, and a fixed frame 3 is fixedly connected to one side of the outer wall of the connecting box 2. A filling layer 4 is fixedly connected to the inner wall of the fixed frame 3, and a frame mechanism is provided on the outer wall of the fixed frame 3. The frame mechanism includes multiple connecting blocks 7 fixed to the upper and lower ends of the fixed frame 3. Each of the multiple connecting blocks 7 is fixedly connected to a buckle 8 on one side. A lock 9 is engaged at the end of the multiple buckles 8 away from the connecting blocks 7. An outer frame 5 is fixedly connected to one side of the multiple lock 9. A textile layer 6 is embedded on one side of the outer wall of the outer frame 5. The textile layer 6 corresponds to the position of the multiple massage heads 16. By setting the connecting blocks 7 and the buckles 8, the outer frame 5 can be fixed to the fixed frame 3 by the lock 9, making the device connection more stable.

[0029] It should be added that, such as Figure 1 and Figure 2 As shown, a restraint mechanism is provided at the top of the fixed frame 3. The restraint mechanism includes a top through rod 11 fixed to the top of the fixed frame 3. A sliding sleeve 12 is slidably connected to the top of the top through rod 11. By setting the top through rod 11, the sliding sleeve 12 can slide to a suitable position. Connecting seats 13 are fixedly connected to both sides of the outer wall of the sliding sleeve 12. A restraint strap 14 is fixedly connected to the end of the two connecting seats 13 away from the sliding sleeve 12. By setting the restraint strap 14, the device can be fixed in the position of the human body to prevent the lumbar support device from falling off the human body.

[0030] In this embodiment, the air pump 20 is operated through the control box 21 (model ECU). The air pump 20 transmits compressed air into the air transmission pipe 19, which in turn transmits the compressed air into multiple pneumatic rods 15. These pneumatic rods 15 drive the massage head 16, which is fixedly connected to one end, to push the textile layer 6 to adjust the thickness of the backrest. This allows for backrest adjustment. By setting the connecting block 7 and the buckle 8, the outer frame 5 is fixed to the fixed frame 3 by the lock 9, making the device connection more stable. By sliding the sliding sleeve 12 to a suitable position on the human body and fixing it to the human body by the restraint strap 14, the device is better secured to the human body, providing relief to the waist area.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
