Problems solved by technology

However, the existing test tube racks have the following disadvantages: 1. The test tubes are relatively loose in the test tube racks, which is not conducive to outdoor work, easy to shake, and has a high breakage rate
2. When the test tube is not in use and is drained, the test tube mouth is in contact with the bottom surface of the test tube rack, which will cause contact pollution

Embodiment 1

[0024] Such as Figure 1 to Figure 4 and Figure 7 The shown test tube rack includes a board, two brackets, a base and a clamp made of elastic material. The two brackets are respectively installed at the two ends of the base, and the height of the bracket is greater than the height of the test tube. The board Installed on the upper end of the bracket, the insertion plate is provided with a plurality of through holes through which the test tube passes, the clamping plate is clamped on the bracket, and the clamping plate is located between the insertion plate and the base, and the clamping plate is provided with There are arc-shaped card positions equal in number to the through holes, and each card position corresponds to the corresponding through hole; the arc angle of the card positions is a, and the size of a is 225°, and the The diameter of the clamping position is smaller than the outer diameter of the test tube to be placed.

Embodiment 2

[0033] This test tube rack is with embodiment 1 except following technical characteristics: as Figure 5 and Figure 6 As shown, the two ends of the clamping plate are provided with clamping grooves, the thickness of the bracket gradually increases from top to bottom, and the clamping plate is clamped with the two brackets through the clamping grooves. This changes the thickness of the bracket to replace the installation groove of embodiment 1, which can ensure the stability of the connection between the clamp and the bracket, and ensure the effective progress of the experimental work.

Embodiment 3

[0035] This test tube rack is the same as embodiment 1 except for the following technical features: the test tube rack includes a board, two brackets, a base and a clamp made of elastic material, and the two brackets are respectively installed at both ends of the base, and the The height of the bracket is greater than the height of the test tube, the inserting plate is installed on the upper end of the support, the inserting plate is provided with a plurality of through holes passed by the test tube, the clamping plate is clamped on the bracket, and the inserting plate is located on the inserting plate Between the base and the base, there are circular-arc-shaped clamping positions equal to the number of through-holes in the clamping plate, and each clamping position corresponds to a corresponding through-hole one by one; the arc angle of the clamping positions is a , the size of this a is 190°, and the diameter of the clamping position is smaller than the outer diameter of the ...

Abstract

The invention discloses a test tube stand. The test tube stand comprises an insertion board, two brackets, a base and a clamping board, wherein the clamping board is made from an elastic material, thetwo brackets are respectively mounted at two ends of the base, the heights of the brackets are larger than the heights of test tubes, the insertion board is mounted at the upper ends of the brackets,a plurality of through holes penetrated by the test tubes are formed in the insertion board, and the clamping board is clamped to the brackets and is located between the insertion board and the base;arc-shaped clamping sites with the same number of the through holes are arranged in the clamping plate and are in one-to-one correspondence with the corresponding through holes; and the arc angles ofthe clamping sites are a, a is more than 180 degrees and less than 270 degrees, and the diameters of the clamping sites are smaller than the outer diameters of to-be-placed test tubes. According to the test tube stand, the test tubes inserted into the through holes are fixed through the clamping plate, so that the shaking of the test tubes is avoided, the breakage of the test tubes caused by thecollision is avoided, the outdoor operation is facilitated, and meanwhile, the draining of the test tubes is facilitated.

Description

technical field [0001] The invention relates to experimental equipment, in particular to a test tube rack. Background technique [0002] Test tube racks are commonly used equipment in current experiments. Present test tube rack mainly is made of base, support and inserting plate, and has some through holes on inserting plate to use for test tube. The principle of use is: when using the test tube, put the bottom of the test tube with liquid down into the test tube socket, the contact between the test tube and the socket is loose, and it is convenient to take and place; when the test tube is not in use, put the empty test tube with the mouth facing down Just put it into the test tube jack, which can not only drain the water, but also prevent dust from falling into the test tube. But the existing test tube rack has the following disadvantages: one, the test tubes are relatively loose in the test tube rack, which is unfavorable for outdoor work, easy to shake, and has a high d...
