Embodiment 1

[0035] An easily adjustable infusion chair with cushioning effect, see Figure 1~2 , including a seat 1, the two sides of the seat 1 are fixedly connected with armrests, the rear end of the seat 1 is provided with a seat back 2, the inner side of the seat back 2 is fixedly installed with a back cushion 3, the seat The lower end of the chair leg 4 is provided with a chair leg 4, and the bottom of the chair leg 4 is fixedly equipped with a universal wheel 5, which is more flexible in movement, and is convenient for quickly transferring a patient who is undergoing infusion in an emergency;

[0036] The seat 1 includes a base 11 and a cushion 12, the base 11 is provided with a cavity with an open top, the cushion 12 is sleeved in the base 11, and can slide along the inner wall of the base 11, the cushion 12 The bottom and the inner wall of the base 11 enclose a buffer cavity 6, and the buffer cavity 6 is provided with a buffer device 7, and the buffer device 7 includes a guide pla...

Embodiment 2

[0040] Embodiment 2 is basically the same as Embodiment 1, and the difference is that the cross section of the guide plate 71 is regular N-gon, N is greater than or equal to 3, and each side of the regular N-gon sidewall is distributed with one or A plurality of gears 74, the side length of the regular N-gon is 0.2 to 0.4 times the width of the seat cushion 12, and the multi-directional arrangement of the gears 74 forms the same strength of support and buffering in all directions, which is beneficial to improve the seat. Comfort and cushioning performance. In this example, see Figure 5 , taking the cross-section of the guide plate 71 as an equilateral triangle as an example, there are three fixed plates 72 and three gears 74, and three fixed plates 72 are arranged on each of the triangular side walls of the guide plate 71. Side outside.

Embodiment 3

[0042] Embodiment 3 is substantially the same as Embodiment 1 or 2, and its difference is: see Image 6 , the bottom end of the guide plate 71 is provided with a limiting plate 77, and the limiting plate 77 is provided with a through hole for the fixing plate 72 to pass through. The outer side of the limiting plate 77 is connected to the buffer chamber 6 The inner wall of the guide plate fits together and forms a T-shaped structure with the guide, so that the guide plate 71 can only do linear reciprocating motion, and the buffer force of the damping spring 75 at its lower part can be evenly transmitted to the guide plate 71, which can better buffer the external impact force. It can play a guiding role in the re-entry process of the seat cushion 12.
