Adjustment limit frames 102 are slidably arranged on the sides of the slide grooves A101, and the side opposite surfaces of the adjustment limit frames 102 are arranged in an inclined arc shape. Limiting grooves 103 are embedded and arranged above the adjustment limit frames 102. There are several limiting grooves 103, which are arranged equidistantly in an arc shape. A limiting card frame 104 is rotatably arranged above the slide groove A101 through a bearing, and the limiting card frame 104 is slidably arranged on the inner side of the limiting groove 103, and the upper part of the inner wall of the heat preservation rack 1 Damping telescopic rods A106 are fixedly installed on both sides, and springs are matched on the outside of the damping telescopic rods A106. A limit pressure plate 107 is fixedly installed between the lower ends of the damping telescopic rods A106. When the staff carries the infusion bottle to the designated patient ward and needs to perform infusion treatment on the patient, the staff pushes the two limit card frames 104 to slide out of the limit groove 103 through the bearing rotation, loosens and pushes the two adjustment limit frames 102 to expand laterally inside the slide groove A101, and then the staff puts the infusion bottle upside down into the insulation rack 1 and pushes the two limit card frames 104 to slide out of the limit groove 103. The adjusting limit frame 102 slides in the opposite direction inside the slide groove A101, so that the side inclined arc surface of the adjusting limit frame 102 contacts the two sides of the surface of the infusion bottle, and limits the infusion bottle inside the heat preservation rack 1, while contacting and squeezing the limit pressing plate 107 to drive the damping telescopic rod A106 and the outer spring to contract, so that the contracted damping telescopic rod A106 and the outer spring produce a reverse thrust on the limit pressing plate 107.

When the staff pushes the two adjustment limit frames 102 to expand on the inner side of the slide A101, the limit block 5 is squeezed and slidable. After the limit slot 103 drives the damping telescopic rod B501 and the outer spring to contract, and the adjustment limit frame 102 is unfolded, the damping telescopic rod B501 and the outer spring rebound limit block 5 slide into the relative inner side of the limit slot 103, the staff puts the infusion bottle upside down into the insulation rack 1, and pushes the two limit blocks 5 to slide out of the limit slot 103, driving the damping telescopic rod B501 and the outer spring to contract, and then pushes the adjustment limit frame 102 to slide in the relative direction inside the slide slot A101, so that the adjustment limit The inclined arc surface on the side of the rack 102 contacts both sides of the surface of the infusion bottle, and limits the infusion bottle inside the insulation rack 1.
