Description

Technical Field

[0001] The utility model relates to a test tube rack, in particular to a test tube rack with a sample adding indicating device, belonging to the technical field of experimental equipment. Background Art

[0002] Test tubes are common and frequently used instruments in laboratories and are indispensable experimental reaction containers. Test tubes often need to be placed on test tube racks. Various experimental reaction operations are performed by adding various reagents or solutions into the test tubes. Common test tubes are made of transparent glass. If it is necessary to add colorless and transparent liquid samples, when large-scale sample addition operations are required, operators often easily confuse the added and unadded samples, which is time-consuming and labor-intensive, and is prone to failure to add samples or repeated additions, resulting in inaccurate sample addition and thus inaccurate experimental results.

[0003] In the prior art, there is a test tube rack for easily marking sampled specimens disclosed in announcement number CN215234390U, which includes a base and a rack, wherein the rack includes an insert plate and a plurality of vertical rods, wherein the insert plate is provided with a plurality of through holes in an array, and the insert plate is fixedly mounted above the base through the vertical rods; the base is provided with a plurality of lifting devices, each of which is respectively fixedly provided with a test tube holder, and each test tube holder is respectively located directly below a through hole in a one-to-one correspondence; the inspector can quickly determine which test tubes have been loaded with samples and which have not been loaded with samples, thereby greatly reducing the occurrence of repeated loading or missing loading of samples. Although the prior art can distinguish whether a test tube has been loaded with samples, in actual operation, each time a sample is loaded into a test tube, a carry key is clicked once, and the loaded test tube is lifted. According to whether the test tubes are lifted, it is easy to determine which test tubes have been loaded with samples and which test tubes have not been loaded with samples. However, when large batches or multiple loadings are required, multiple test tubes need to be repeatedly loaded with samples. Therefore, the operator is required to manually click the carry key multiple times, which greatly increases the operator's workload and is inconvenient to use. In addition, the existing technology can only distinguish whether the test tubes have been loaded with samples. For experimental operations that require multiple loadings, although the lifting device can be reset and then the loading distinction can be made again, the operator must always remember the operating requirement of manually clicking the carry key after loading the samples. As a result, the operator's attention is easily too focused on the repeated cycle of loading and then clicking the carry key during the entire loading process, which may cause the operator to miss a certain sample.

[0034] Embodiment 2

[0035] Improvements based on Example 1:

[0036] like Figures 1 to 6 As shown, the test tube rack body 1 includes a top plate 11, a middle partition plate 12, a base 13 and a support rod 14, the top plate 11, the middle partition plate 12 and the base 13 are arranged in parallel from top to bottom, the top plate 11 and the base 13 are connected with the support rod 14 at the four corners, the middle partition plate 12 is provided with a support rod through hole 122 at the four corners, and the rod body of the support rod 14 is fixed in the support rod through hole 122, and the four corners of the lower plate surface of the base 13 are connected with a stabilizing foot 132, so that the test tube can be placed in the test tube rack by the combination of the top plate 11, the middle partition plate 12, the base 13 and the support rod 14. The rack body 1 maintains structural stability and can stably place the test tube rack body 1 on the operating table through the stabilizing legs 132. A plurality of top plate plug holes 111 are opened through the top plate 11, and a plurality of partition plate plug holes 121 are opened on the middle partition plate 12. The top plate plug holes 111 and the partition plate plug holes 121 are arranged in a one-to-one correspondence. The glass test tube 2 can be inserted into the test tube rack body 1 through the opened plug holes to ensure that the glass test tube 2 is placed vertically on the test tube rack body 1, thereby facilitating the addition of samples into the glass test tube 2.

[0037] Furthermore, an indicator light placement groove 112 is provided on the upper surface of the top plate 11, and the indicator light placement groove 112 is located on one side of the top plate socket 111. A sensor placement groove 131 is provided on the upper surface of the base 13, and the sensor placement groove 131 is located directly below the top plate socket 111. The indicator light 3 can be installed on one side of each glass test tube 2 through the indicator light placement groove 112, and the weight sensor 5 can be installed directly below the glass test tube 2 through the sensor placement groove 131, so that each glass test tube 2 is equipped with a weight sensor 5 and an indicator light 3, so as to realize separate indication of each glass test tube 2 when adding samples.

[0038] Furthermore, a control board 6 is provided on the test tube rack body 1, and the control board 6 is embedded in the base 13. The control board 6 is electrically connected to the weight sensor 5 and the indicator light 3 equipped with each glass test tube 2 through the connecting line 61, and the control board 6 is electrically connected to the external power supply through the power line 62, so that the control board 6 can receive the weight change signal of the glass test tube 2 monitored by each weight sensor 5 when the sample is added, and can control the indicator light 3 to light up in different colors based on the weight change signal, so that the operator can intuitively and clearly know whether the glass test tube 2 has been added.

[0039] Furthermore, a control switch 63 and a reset switch 64 are installed on one long side of the base 13, and the control switch 63 and the reset switch 64 are both electrically connected to the control board 6, so that the control board 6 can be powered on and off by the control switch 63, and when all the glass test tubes 2 on the test tube rack are loaded with samples once, the indicator light 3 can be restored to its initial state by pressing the reset switch 64, so that the color indicator can be lit up for the next loading operation, so as to avoid confusing the operator and missing the loading of samples into a certain glass test tube 2 when performing large-scale loading operations.

[0040] Furthermore, a counting display screen 65 is installed on one long side of the base 13. The control switch 63, the reset switch 64 and the counting display screen 65 are all located on the side close to the operator. The counting display screen 65 is electrically connected to the control board 6. Each time the reset switch 64 is pressed to facilitate the next sample addition operation, the counting display screen 65 will display the number of times the reset switch 64 is pressed, that is, the number of sample addition operations performed in the glass test tube 2 can be accurately recorded to avoid confusing the operator and missing the addition of a certain sample when performing multiple sample addition operations. In addition, the control switch 63, the reset switch 64 and the counting display screen 65 are located close to the operation side, which is also convenient for the operator to use.

[0041] like Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, the indicator light 3 includes a lamp holder 31, a red light bead 32 and a green light bead 33. The lamp holder 31 is clamped in the indicator light placement groove 112. The red light bead 32 and the green light bead 33 are connected to the lamp holder 31 in a side-by-side manner, and the red light bead 32 and the green light bead 33 are arranged in parallel. The red light bead 32 is in a lighted state when no sample is added, and the green light bead 33 is in a lighted state when no sample is added, so that at the initial stage of sample addition, the red light bead 32 of all the indicator lights 3 is in a lighted state, and then after each glass test tube 2 is added with a sample, the sample addition signal received by the control board 6 cuts off the power to the red light bead 32 and supplies power to the green light bead 33, so that the red light bead 32 is turned off and the green light bead 33 is lit, so that the glass test tube 2 with the sample added can be distinguished from the glass test tube 2 without the sample added.

[0042] Furthermore, the top of each weight sensor 5 is connected to a bottom sleeve 4, and a sensor docking groove 43 is provided at the center of the lower end surface of the bottom sleeve 4, and the docking end of the weight sensor 5 is inserted into the sensor docking groove 43. The bottom end of the glass test tube 2 can be supported by the bottom sleeve 4, and when the sample is added to the glass test tube 2, the weight after the sample is added can be vertically transferred downward to the weight sensor 5, thereby ensuring that the weight sensor 5 can accurately capture the weight change information after the sample is added.

[0043] Furthermore, an arc-shaped inner cavity 41 is formed at the upper end of the bottom sleeve 4, and a plurality of rubber protrusions 42 are embedded in the bottom surface of the arc-shaped inner cavity 41, so that the arc-shaped bottom end of the glass test tube 2 can be stuck in the arc-shaped inner cavity 41, and the bottom end of the glass test tube 2 is flexibly supported by the rubber protrusions 42, so that when the glass test tube 2 is placed, the bottom end of the test tube can be prevented from being broken due to the rigid contact between the bottom end of the test tube and the arc-shaped inner cavity 41 of the bottom sleeve 4.

[0044] Furthermore, a plurality of wire tubes 7 are provided on the test tube rack body 1, and the wire tubes 7 are vertically connected below the indicator light 3. A wire tube through-hole 123 is provided on the middle partition plate 12 of the test tube rack body 1. The tube body of the wire tube 7 passes through the wire tube through-hole 123, and a connecting line 61 is passed through the wire tube 7, so that a hidden design of the connecting line 61 can be realized, thereby avoiding touching the connecting line 61 when placing or taking the glass test tube 2.

[0045] Working principle: First, the power supply of the test tube rack is turned on. At the beginning of sample addition, the red light beads 32 of all indicator lights 3 are in a lighted state. Then, after each glass test tube 2 is added, the weight change signal of the glass test tube 2 monitored by each weight sensor 5 during sample addition is received through the control board 6, and the red light beads 32 of the indicator lights 3 can be controlled to turn off and the green light beads 33 can be turned on based on the weight change signal, thereby distinguishing the added glass test tubes 2 from the unadded glass test tubes 2. When all the glass test tubes 2 on the test tube rack are added once, the indicator lights 3 can be restored to the initial state by pressing the reset switch 64, thereby facilitating the color lighting indication for the next sample addition operation, and each time the reset switch 64 is pressed for the next sample addition operation, the counting display screen 65 will display the number of times the reset switch 64 is pressed, that is, the number of times the sample addition operation is performed in the glass test tube 2 can be accurately recorded to avoid confusing the operator and missing the addition of a certain sample when performing multiple sample addition operations.
