[0037] The traditional support frame for the ventilator pipeline is a fixed structure, and the height of the raised pipeline is a fixed value. However, in practice, due to the different ages of patients, the height of the head of the patient when lying on the bed is also different. If the height of the breathing pipeline is raised too low, there is still a risk of breaking the tube, which is not conducive to the patient's oxygen inhalation. The utility model provides a first adjustment component 2 between the machine body component 1 and the base 4, which is convenient for adjusting the height of the machine body component 1, thereby raising the height of the clamping and stabilizing component and the pipeline, so that the height of the ventilator pipeline is adjustable. The user can use the first adjustment component 2, and the user manually raises or lowers the height of the upper plate 22, and the two groups of rotating rods 215 rotate. At this time, the two groups of upper sliders 216 and the two groups of lower sliders 213 all slide. When the upper plate 22 is lifted, the two adjacent groups of lower sliders 213 move closer to each other, and the two adjacent groups of upper sliders 216 also move closer to each other. When the height of the upper plate 22 is determined When the upper plate 22 is lowered, the upper plate 22 is manually adjusted to lower the height. At this time, the two adjacent upper sliders 216 and the two adjacent lower sliders 213 move away from each other, and finally extend into the slot 214 through the driving block 212, that is, the driving component 21 is fixed. This arrangement can adjust the height of the main body assembly 1 through the adjustment component, and then the ventilator pipeline support frame can adjust the height according to patients with different head sizes, so that the pipeline is smooth, thereby raising the ventilator pipeline support to a certain height, which is beneficial for the ventilator to provide oxygen to the patient and improves the scope of application of the device.
