Description

Technical Field

[0001] This utility model relates to the technical field of sampling tube placement equipment, specifically a sampling tube placement device for pharmaceutical experiments. Background Technology

[0002] In pharmaceutical experiments, sampling tubes come in a variety of sizes, and common test tube racks are difficult to accommodate sampling tubes of different diameters and lengths. This can cause the sampling tubes to shake or even tip over when placed, which may not only cause the samples to spill and affect the experimental results, but may also lead to the breakage of the sampling tubes and increase the experimental costs.

[0003] In addition, this placement method does not take into account the protection requirements of the sample. The sampling tube is easily affected by external factors such as dust and collisions, which may adversely affect the purity of the sample and the accuracy of the experimental results.

[0004] In summary, existing methods for placing sampling tubes in pharmaceutical experiments have many shortcomings. There is an urgent need for a method that can accommodate various sizes of sampling tubes and prevent them from being affected by external dust or impacts, in order to meet the growing needs of pharmaceutical experiments and improve the accuracy and efficiency of experiments.

[0005] Therefore, a sampling tube placement device for pharmaceutical experiments is needed. Utility Model Content

[0006] The purpose of this invention is to provide a sampling tube placement device for pharmaceutical experiments. By using this device, the problems of existing test tube racks being unable to accommodate various sizes of sampling tubes and being unable to prevent sampling tubes from being exposed to external dust and collisions, which greatly reduces the accuracy of experimental results, are solved.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical experimental sampling tube placement device, including a placement box, a box cover at the top of the placement box, a test tube rack inside the placement box, the test tube rack including a base plate, a partition fixedly installed at the top of the base plate, and multiple telescopic rods fixedly installed at the bottom of the base plate. The telescopic rods are fixedly connected to the bottom surface of the inner wall of the placement box, and a buffer spring is sleeved on the outer side of the telescopic rods. The upper end of the buffer spring is fixedly connected to the base plate, and the lower end of the buffer spring is fixedly connected to the bottom surface of the inner wall of the placement box. Multiple placement slots are opened through the interior of the partition, and clamping members are symmetrically arranged on the inner side of the placement slots.

[0008] The clamping components include a rubber ring, with a telescopic rod two fixedly installed at one end of the rubber ring. The telescopic rod two is fixedly connected to the surface of the placement groove. A spring is sleeved on the outside of the telescopic rod two, with one end of the spring fixedly connected to the rubber ring and the other end of the spring fixedly connected to the surface of the placement groove. When a sampling tube needs to be placed, the open end of the sampling tube faces upward, and then the lower end of the sampling tube is used to squeeze the rubber ring, thereby compressing the spring until the bottom of the sampling tube contacts the bottom plate. At this time, the clamping components symmetrically arranged inside the placement groove will adaptively clamp the sampling tube, thus adapting to sampling tubes of different specifications. On the one hand, this greatly improves its practicality, and on the other hand, it effectively avoids the shaking of the sampling tube. Through the setting of the buffer spring, the vibration transmitted from the placement box can be effectively filtered, reducing the impact on the sample and thus improving the accuracy of the experimental results.

[0009] Preferably, a plurality of rubber recesses are fixedly installed on the upper surface of the base plate, and the plurality of rubber recesses correspond one-to-one with a plurality of placement slots. The setting of the rubber recesses can provide good protection for the bottom of the sampling tube and avoid damage to the sampling tube caused by hard contact.

[0010] Preferably, multiple sliding columns are fixedly installed on the inner wall surface of the placement box. The sliding columns are matched with the base plate and are slidably connected. By setting the sliding columns, the test tube rack can only move vertically during the process of filtering vibration by the buffer spring, thereby avoiding lateral swaying and collision with the inner wall of the placement box, which would cause irreversible impact on the experimental results.

[0011] Preferably, the upper surface of the box is provided with a groove, and a fixing strip is fixedly installed at the lower end of the box cover. The fixing strip fits into the groove. When it is not necessary to place the sampling tube, the fixing strip is embedded in the groove by closing the box cover, which effectively prevents dust in the air from entering and further reduces the impact on the sample.

[0012] Preferably, the upper surface of the storage box has multiple slots, each slot containing an elastic element. Multiple blocks are fixedly installed at the lower end of the lid, each block corresponding to a slot. Each block has a slot. The elastic element includes a pull rod that passes through the storage box and slides along it. One end of the pull rod is fixedly fitted with a block, and the other end with a pull ring. One end of the block is fixedly fitted with a compression spring, the end of which is away from the block fixedly connected to the surface of the slot. When the lid needs to be opened, pulling the pull ring moves the pull rod and the block, causing the block to compress the spring and disengage from the slot. The lid can then be opened. When the lid needs to be closed, simply align the block with the slot and press it in. During the pressing process, the block forces the block to compress the spring until they align again.

[0013] Preferably, the multiple sets of clamping members have identical structural compositions.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention proposes a pharmaceutical experimental sampling tube placement device. When a sampling tube needs to be placed, the open end of the sampling tube faces upward, and then the lower end of the sampling tube is used to squeeze the rubber ring, thereby compressing the spring until the bottom of the sampling tube contacts the base plate. At this time, the clamping parts symmetrically arranged inside the placement groove will adaptively clamp the sampling tube, thus adapting to sampling tubes of different specifications. On the one hand, this greatly improves its practicality, and on the other hand, it effectively avoids the shaking of the sampling tube. Through the setting of the buffer spring, the vibration transmitted from the placement box can be effectively filtered, reducing the impact on the sample and thus improving the accuracy of the experimental results.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1-3 , Figure 5 A pharmaceutical experimental sampling tube placement device includes a placement box 1, a box cover 2 at the upper end of the placement box 1, a test tube rack 3 inside the placement box 1, the test tube rack 3 including a base plate 31, a partition 32 fixedly installed at the upper end of the base plate 31, and a plurality of telescopic rods 33 fixedly installed at the lower end of the base plate 31. The telescopic rods 33 are fixedly connected to the bottom surface of the inner wall of the placement box 1. A buffer spring 34 is sleeved on the outer side of the telescopic rods 33. The upper end of the buffer spring 34 is fixedly connected to the base plate 31, and the lower end of the buffer spring 34 is fixedly connected to the bottom surface of the inner wall of the placement box 1. A plurality of placement slots 321 are opened through the interior of the partition 32, and clamping members 322 are symmetrically arranged on the inner side of the placement slots 321.

[0026] The clamping component 322 includes a rubber ring 3221. A telescopic rod 3222 is fixedly installed at one end of the rubber ring 3221. The telescopic rod 3222 is fixedly connected to the surface of the placement groove 321. A spring 3223 is sleeved on the outside of the telescopic rod 3222. One end of the spring 3223 is fixedly connected to the rubber ring 3221, and the other end of the spring 3223 is fixedly connected to the surface of the placement groove 321. When a sampling tube needs to be placed, the open end of the sampling tube faces upward, and then the lower end of the sampling tube is used to squeeze the rubber ring 3221. Then, the spring 3223 is compressed until the bottom of the sampling tube contacts the base plate 31. At this time, the clamping parts 322, which are symmetrically arranged inside the placement groove 321, will adaptively clamp the sampling tube to adapt to different specifications of sampling tubes. On the one hand, this greatly improves its practicality, and on the other hand, it effectively avoids the shaking of the sampling tube. By setting the buffer spring 34, the vibration transmitted from the placement box 1 can be effectively filtered, reducing the impact on the sample and thus improving the accuracy of the experimental results.

[0027] Combination Figure 2 Multiple rubber recesses 311 are fixedly installed on the upper surface of the base plate 31. The multiple rubber recesses 311 correspond one-to-one with multiple placement slots 321. The setting of the rubber recesses 311 can provide good protection for the bottom of the sampling tube and avoid damage to the sampling tube caused by hard contact.

[0028] Combination Figure 2 Multiple sliding columns 14 are fixedly installed on the inner wall surface of the placement box 1. The sliding columns 14 are matched with the base plate 31 and are slidably connected. By setting the sliding columns 14, the test tube rack 3 can only move vertically during the process of filtering vibration by the buffer spring 34, thereby avoiding lateral shaking and collision with the inner wall of the placement box 1, which would have an irreversible impact on the experimental results.

[0029] Combination Figure 2 , Figure 4 The upper surface of the box 1 is provided with a groove 13, and a fixing strip 23 is fixedly installed at the lower end of the box cover 2. The fixing strip 23 fits into the groove 13. When it is not necessary to place the sampling tube, the fixing strip 23 is embedded in the groove 13 by closing the box cover 2, which effectively prevents dust in the air from entering and further reduces the impact on the sample.

[0030] Combination Figure 2 , Figure 4 , Figure 6 The upper surface of the storage box 1 has multiple slots 11, and the interior of each slot 11 contains an elastic element 12. The lower end of the box cover 2 is fixedly fitted with multiple blocks 21, each corresponding to a slot 11. Each block 21 has a slot 22. The elastic element 12 includes a pull rod 121 that passes through the storage box 1 and slides along it. One end of the pull rod 121 is fixedly fitted with a block 22, and the other end is fixedly fitted with a pull ring 123. One end of the block 22 is fixedly fitted with a compression spring 124, which is located away from the block 2. One end of 122 is fixedly connected to the surface of slot 11. When the lid 2 needs to be opened, the pull ring 123 is pulled to drive the pull rod 121 and the second locking block 122, so that the second locking block 122 compresses the compression spring 124 and then disengages from the slot 22. At this time, the lid 2 can be opened. When the lid 2 needs to be closed, simply align the first locking block 21 with the slot 11 and press it in. During the pressing process, the first locking block 21 will force the second locking block 122 to squeeze the compression spring 124 until the second locking block 122 corresponds to the slot 22 and then re-engages.

[0031] Combination Figure 5 The multiple sets of clamping components 322 have completely identical structural compositions.
