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, an...

Method used

As shown in Figure 7, the two ends of described clamping plate are provided with draw-in groove, and described support is provided with the installation groove that matches with draw-in groove, and the draw-in groove that is positioned at clamping plate two ends is clamped in two supports respectively the installation slot. The structure is simple, and it is convenient to disassemble and assemble the clamping board, and it is also convenient for processing and manufacturing.

The thickness of described pallet is b, and the size of this b is 5mm. The proper thickness of the clamping plate can further ensure the firmness when the clamping position clamps the test tube.

This test tube rack is with embodiment 1 except following technical characteristics: as shown in Figure 5 and Figure 6, the two ends of described clamping plate are provided with draw-in groove, and the thickness of described support gradually increases from up to down, so The clamping board is clamped with the two brackets through the clamping slot. 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.

This test tube rack is with embodiment 1 except following technical characteristics: test tube rack, comprises the clamping plate that a plate, two supports, base and elastic material are made, and two supports are respectively installed in 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.

Example Embodiment

[0023] Example 1

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

[0025] When the test tube rack is in working state, remove the card plate from the bracket and put it aside, then the test tube can be easily taken out from the test tube rack or placed upright in the through hole to ensure the effective execution of the experiment;

[0026] When the test tube is idle and drained, the card plate is clamped to the bracket. When the test tube passes through the through hole and the bottom of the test tube is in contact with the base, the test tube will pass through the corresponding card position at the same time, because the diameter of the card position is slightly smaller than that of the test tube. In other words, there will be an interference fit between the test tube and the clamping position, and the test tube will be fixed by the clamping position in the clamping plate without shaking. Therefore, when the entire test tube rack is turned upside down, the test tube will not fall off because the test tube is clamped by the card man, and the test tube mouth is in a suspended state at this time, and the test tube mouth will not be in contact with other components, so that the test tube can be drained, and Contact contamination will not occur.

[0027] The card board is made of rubber or plastic. It is made of elastic rubber or plastic, which can further ensure the stability and firmness of the test tube when clamped in place, and ensure the effective drainage of water.

[0028] like Figure 7 As shown, two ends of the card board are provided with card slots, and the brackets are provided with installation slots matching the card slots, and the card slots at both ends of the card plate are respectively clamped to the installation slots of the two brackets. The structure is simple, the disassembly and assembly of the card board is convenient, and the processing and manufacturing are also convenient.

[0029] The thickness of the card board is b, and the size of this b is 5mm. The appropriate thickness of the clamping plate can further ensure the firmness of the clamping position when clamping the test tube.

[0030] The distance between the plug board and the card board is c, and the size of this c is 45mm. Appropriate distances are used between the inserting plate and the clamping plate to constrain the different positions of the test tube, which further ensures the stability during clamping and fixing.

[0031] The upper surface of the base is provided with grooves, and these grooves correspond to the through holes one-to-one. This avoids slippage of the test tube, further ensuring that experiments are performed efficiently.

Example Embodiment

[0032] Example 2

[0033] This test tube rack is the same as Example 1 except the following technical features: Figure 5 and Image 6 As shown, two ends of the card plate are provided with card slots, the thickness of the bracket increases gradually from top to bottom, and the card plate is clamped with the two brackets through the card slots. This changes the thickness of the bracket to replace the installation slot of Embodiment 1, which can ensure the stability of the connection between the card board and the bracket, and ensure the effective progress of the experimental work.

Example Embodiment

[0034] Example 3

[0035] This test tube rack is the same as Embodiment 1 except for the following technical features: the test tube rack includes a plug board, two brackets, a base and a card board made of elastic material, and the two brackets are respectively installed on both ends of the base, and the described The height of the bracket is greater than the height of the test tube, the insert plate is installed on the upper end of the bracket, the insert plate is provided with a plurality of through holes that are passed through by the test tube, the card plate is clamped on the bracket, and the card plate is located on the insert plate. Between the base and the base, the card plate is provided with an arc-shaped card position equal to the number of through holes, and each card position corresponds to the corresponding through hole one-to-one; the arc angle of the card position is a , the size of this a is 190°, and the diameter of the latch is smaller than the outer diameter of the test tube to be placed. The proper angle of the clamping position can ensure a firm clamping of the test tube.
