Air bag, the air bag side of rectangular-shape sets charge and discharge gas port and filling port, is provided with the upper surface of air bag Multiple perpendicular to balloon surface and vertically arranged sub- air bag,

Base plate, the base plate middle part carries out bonding connection by the air bag being bonded,

And top board, multiple circular holes are provided with top board, the circular hole is corresponded with the sub- air bag, and sub- air bag is swollen The circular hole is sleeved on the root of sub- air bag under swollen state.

Further, there is downward bending portion on the top board, the base plate surrounding is buckled into and fastens shape in bending part Integrally.

Further, there is bulb in the middle part of the sub- air bag.

Further, the base plate is working of plastics.

Further, the top board is working of plastics.

Further, the air bag is rubber parts.

The beneficial effects of the utility model are：

Simple structure, only with three parts, low cost.

Under deflation status, it is easy to storage, forms portable structure, and air bag is in the guard space of base plate and top board Interior, security protection effect is good.

Under inflated condition, operating efficiency can be improved with rapid shaping.

Under water-filling state, internal heat supply is formed to test tube therein and heated at the top of sub- air bag, accelerates test tube Dry, and be conducive to being maintained at and dry shape body.

Specific embodiment

As shown in Figures 1 to 4, a kind of rack for test tube, is the improvement to traditional rack for test tube, traditional rack for test tube be it is wooden or Person's stainless steel, jack and column are provided with rack for test tube, wherein jack is used for the upright placement of test tube, and column is used for The upside down of test tube.

Traditional wooden or metal rack for test tube, its hardness is higher than test tube, easily makes after test tube encounters rack for test tube Tube breaking is obtained, breakage is in turn resulted in.

Current solution is to handle with care.

The utility model is namely based on a kind of rack for test tube of this problem exploitation, possesses following characteristic：Flexibility, can conveniently receive Receive, with following design feature.

Air bag 1, air bag is rectangular-shape, and the side of air bag is provided with a charge and discharge gas port 11 and a filling port 12, Inflate or deflate to it by charger, multiple is provided with perpendicular to balloon surface and vertical in the upper surface of air bag 1 The sub- air bag 2 for setting, the sub- air bag is uniform, and is multiple.

Base plate 3, base plate is working of plastics, and bonding connection is carried out by the air bag being bonded, and abutting edge 31 is located at bottom center, When being inflated in air bag, the trend being adjacent to relative to base plate is arranged at air bag bottom, with reference to Fig. 4.

Top board 4, top board is made using engineering plastics, with excellent decay resistance, multiple circles is provided with top board Hole, corresponds with above-mentioned sub- air bag, and above-mentioned top board passes through sub- air bag and is sleeved on the root of sub- air bag from top to bottom.

The flange 41 with downward bending, forms bending part on the top plate 4, and bending part has the buckle of indent, when base plate 3 Surrounding is buckled into bending part, can fasten to form one.

In the deflated condition, with reference to Fig. 4, now, test tube can upside down and be fastened on sub- air bag.

It is different according to occupation mode, hot water can be inflated or fill, or mixing is filled with.

With reference to Fig. 5,2 gases of atmospheric pressure are filled with completely in air bag.

With reference to Fig. 6, air 51 and water 52 are filled with simultaneously in air bag, the group effect of water is counterweight, improve stability.

With reference to Fig. 7, a small amount of air is now filled, be then charged with a large amount of hot water, hot junction is formed in one end of sub- air bag, accelerate test tube The evaporation of interior moisture.

With reference to Fig. 8, hot water is full of in air bag.

Embodiment two

With reference to Fig. 9, some bulbs 21 are formed at the middle part of sub- air bag 2, form a kind of between four adjacent sub- air bags Clamping effect, can be upright by test tube and inserts wherein.

The presence of bulb, can also effectively form to inverted test tube and lift, it is to avoid examination is touched at the top of sub- air bag Bottom of the tube, strict occasion is required for some.

After deflating and discharging water, air bag and sub- air bag are shunk, and formation is caved in, so after being fastened when top board and base plate, just Air bag and sub- air bag can be fastened in space between two plates, form a kind of container structure, occupied little space, be easy to deposit Storage.
