Description

Technical Field

[0001] This application belongs to the field of liquid concentration testing technology, and more specifically, relates to a sample transport device for liquid sample concentration testing. Background Technology

[0002] In many fields such as medical diagnostics, environmental monitoring, food safety testing, and bioscience research, accurate testing of liquid sample concentrations is crucial for obtaining reliable data and ensuring research quality and testing accuracy. Sample transport, as a vital intermediate step connecting sample collection points and testing laboratories, directly impacts sample quality and the accuracy of subsequent test results due to the performance of the transport equipment used.

[0003] Currently, when using existing sample transport boxes for sample transportation, the test tubes containing the samples are usually sealed at the opening and then squeezed and stacked inside the box. During transportation, the test tubes are very likely to collide with each other, causing sample leakage or even damage to the test tubes. Utility Model Content

[0004] Based on the above-mentioned technical problems, this application provides a sample transport device for liquid sample concentration testing, in order to solve the technical problem that in the prior art, sample leakage or even damage to the test tubes is easily caused by collisions between test tubes during the transport process.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a sample transport device for liquid sample concentration testing is provided, comprising: a transport box, a bracket slidably disposed inside the transport box, and a placement rack placed on the bracket. An elastic part is provided between the bracket and the bottom surface of the transport box for pushing the bracket to move away from the bottom of the transport box. The placement rack is provided with a plurality of positioning holes for receiving test tubes. An elastic claw is fixed to the inner edge of each positioning hole. The outer diameter of the test tube is larger than the inner diameter of the elastic claw.

[0006] Furthermore, the transfer box includes a box body and a box cover hinged to the top of the box body. The elastic part consists of multiple springs, which are evenly distributed on the bottom surface inside the box body. Shock-absorbing sponge is also filled between the bracket and the bottom of the transfer box.

[0007] Furthermore, there are multiple placement racks, and multiple partitions are fixed inside the rack. The multiple partitions divide the interior of the rack into multiple accommodating spaces, and the multiple placement racks are respectively located in the multiple accommodating spaces.

[0008] Furthermore, a handle is fixedly provided on the partition, and when the transfer box is in the open state, the height of the top of the handle is higher than the height of the top of the box body.

[0009] Furthermore, a cushioning sponge is fixed on the side of the box lid near the box body. When the transport box is closed, the cushioning sponge abuts against the top of the handle.

[0010] Furthermore, the bottom surface of the bracket is provided with multiple through-holes for leakage.

[0011] Furthermore, the placement rack includes a base plate, a first positioning plate, and a second positioning plate arranged at intervals from bottom to top. The four corners of the base plate, the first positioning plate, and the second positioning plate are fixedly connected by connecting rods. A plurality of positioning holes are respectively opened on the first positioning plate and the second positioning plate, and the plurality of positioning holes of the first positioning plate and the plurality of positioning holes of the second positioning plate correspond to each other.

[0012] Furthermore, the base plate is provided with concave, crown-shaped grooves that are adapted to the bottom surface of the test tube, corresponding to the plurality of positioning holes.

[0013] Furthermore, the elastic claw includes an annular piece, the outer edge of which is fixedly connected to the inner edge of the positioning hole. The inner edge of the annular piece is provided with a plurality of through grooves, which are evenly arranged circumferentially along the inner edge of the annular piece. One end of each through groove is connected to the central hole of the annular piece, and the other end of each through groove extends toward the outer edge of the annular piece. The annular piece between two adjacent through grooves forms an elastic piece.

[0014] Compared with the prior art, the beneficial effects of the sample transport device for liquid sample concentration testing provided in this application are: 1. An elastic section is installed between the bracket and the bottom of the transport box. When encountering bumps or vibrations during transport, the elastic section can absorb and disperse energy through its own elastic deformation, reducing the impact force on the bracket and protecting the test tubes and samples. At the same time, an elastic claw is set on the inner edge of the positioning hole. The elastic plate of the elastic claw can be adaptively adjusted according to the diameter of the test tube, which can tightly hold the outer wall of test tubes of different sizes, realize the stable fixation of the test tubes, and prevent the test tubes from shaking, colliding or tipping over during transport, thus ensuring the safety of the samples.

[0015] 2. By setting handles on the tray, it is easy to pick up and put down the tray. At the same time, the cushioning sponge abuts against the top of the handle to provide further cushioning for the tray and the placement rack, thus better protecting the sample.

[0016] 3. With multiple through-holes on the bottom of the holder, if a test tube leaks, the liquid sample will flow out of the holder through the through-holes, preventing it from accumulating in the holder and contaminating other test tubes. Attached Figure Description

[0025] Please refer to the following: Figures 1 to 4 As shown, the following describes a sample transport device for liquid sample concentration testing provided by an embodiment of this application. The sample transport device for liquid sample concentration testing according to this utility model includes a transport box 1, a tray 2, and a placement rack 3. The transport box 1 includes a box body 11 and a box lid 12. In this embodiment, the box body 11 is a rectangular box with a hollow interior and an open top. The box lid 12 covers the open end of the box body 11. It should be noted that one end of the box lid 12 is hinged to one side of the top of the box body 11, and the other side of the box body 11 is provided with a lock 13 as in the prior art to facilitate opening and closing the transport box 1, which will not be described in detail here.

[0026] The bracket 2 is used to support the placement rack 3. The bracket 2 is slidably disposed inside the box 11 of the transfer box 1. An elastic part is provided between the bracket 2 and the bottom surface of the transfer box 1, so as to push the bracket 2 away from the transfer box 1. Specifically, the elastic part is a plurality of springs 14, which are evenly distributed on the bottom surface inside the box 11. The two ends of the springs 14 abut against the bottom surface inside the box 11 and the bottom surface of the bracket 2, respectively. In this way, when the bracket 2 is placed inside the box 11, the springs 14 will support the bracket 2. During the transfer process, if it encounters bumps or vibrations, the springs 14 will absorb and disperse energy through their own elastic deformation, reducing the impact force on the bracket 2. Preferably, shock-absorbing sponge 16 is also filled between the bracket and the bottom of the transfer box, so as to reduce the damage to the test tube 4 caused by repeated vibrations generated by the springs 14 during the buffering process.

[0027] The placement rack 3 is placed on the bracket 2. The placement rack 3 has multiple positioning holes 331 for receiving test tubes 4, which are used to hold multiple test tubes 4 for storing samples. Specifically, the placement rack 3 includes a base plate 31, a first positioning plate 32, and a second positioning plate 33 arranged at intervals from bottom to top. The four corners of the base plate 31, the first positioning plate 32, and the second positioning plate 33 are fixedly connected by connecting rods 35. Multiple positioning holes 331 are respectively opened on the first positioning plate 32 and the second positioning plate 33, and the multiple positioning holes 331 of the first positioning plate 32 and the multiple positioning holes 331 of the second positioning plate 33 correspond to each other. In practice, after the test tubes 4 are passed through the positioning holes 331 of the first positioning plate 32 and the second positioning plate 33, the bottom of the test tubes 4 will be placed on the base plate 31. The test tube 4 is more stably fixed by a multi-layer positioning structure, that is, the test tube 4 is limited by the first positioning plate 32 and the second positioning plate 33 to prevent the test tube 4 from tilting or shaking during transportation, thereby improving the fixation effect of the test tube 4 and ensuring the safety of the sample.

[0028] Preferably, the base plate 31 has a plurality of positioning holes 331 corresponding to a spherical crown-shaped groove 311 that is adapted to the bottom surface of the test tube 4. When the test tube 4 is placed in the positioning hole 331, the bottom surface of the test tube 4 will be embedded in the spherical crown-shaped groove 311. By increasing the contact area with the bottom surface of the test tube 4 through the spherical crown-shaped groove 311, the pressure on the bottom of the test tube 4 can be more evenly distributed, avoiding concentrated stress from damaging the test tube 4, thereby improving the stability of the test tube 4 on the placement rack 3.

[0029] In this embodiment, there are multiple placement racks 3, and multiple partitions 21 are fixed inside the bracket 2. The multiple partitions 21 divide the interior of the bracket 2 into multiple accommodating spaces 22, and the multiple placement racks 3 are respectively located in the multiple accommodating spaces 22. By setting multiple partitions 21, the shaking of the placement racks 3 during transportation can be effectively avoided, further ensuring the stability of the test tubes 4, reducing the impact of shaking on the samples, and improving the safety and reliability of sample transportation.

[0030] Preferably, a handle 23 is fixed on the partition 21 to allow the bracket 2 to be removed from the transfer box 1. In this embodiment, when the transfer box 1 is open, the top of the handle 23 is higher than the top of the box body 11 (it should be noted that at this time, the elastic part acts on the bottom of the bracket 2, lifting the bracket 2, so the top of the handle 23 is higher than the top of the box body 11). Therefore, when the box lid 12 is closed, since the top of the handle 23 is higher than the top of the box body 11, the spring 14 will be in a certain compressed state. If the transfer box 1 is subjected to external impact, the further compression of the spring 14 can provide a certain buffer space and reduce the swaying amplitude of the bracket 2.

[0031] Preferably, a cushioning sponge 15 is fixed on the side of the lid 12 near the box body 11. When the transport box 1 is closed, the cushioning sponge 15 abuts against the top of the handle 23. This allows the cushioning sponge 15 to absorb energy through its own deformation, providing further cushioning for the bracket 2 and the placement rack 3.

[0032] Preferably, the bottom surface of the tray 2 has multiple through-holes 24 for leakage. During transport, if any individual test tube 4 leaks, the liquid sample will flow out of the tray 2 through the leakage holes 24 (flowing out between the box 11 and the tray 2), thus avoiding contamination of other test tubes 4 and samples.

[0033] In this embodiment, an elastic claw 34 is fixed to the inner edge of each positioning hole 331, and the outer diameter of the test tube 4 is larger than the inner diameter of the elastic claw 34. Therefore, the elastic claw 34 will fit tightly against the outer wall of the test tube 4 due to its own elasticity, achieving stable fixation of the test tube 4 and preventing it from shaking, colliding, or tipping over during transport. At the same time, the design of the elastic claw 34 can accommodate test tubes 4 of different diameters to a certain extent.

[0034] Specifically, the elastic claw 34 includes an annular plate 341. The outer edge of the annular plate 341 is fixedly connected to the inner edge of the positioning hole 331. The inner edge of the annular plate 341 is provided with multiple through grooves 342, which are evenly arranged circumferentially along the inner edge of the annular plate 341. One end of the through groove 342 is connected to the central hole of the annular plate 341, and the other end of the through groove 342 extends towards the outer edge of the annular plate 341. The annular plate 341 between two adjacent through grooves 342 forms an elastic plate. When the test tube 4 is inserted into the positioning hole 331, the elastic plate will undergo elastic deformation due to the compression of the test tube 4, thereby tightly holding the outer wall of the test tube 4. The elastic plate can adaptively adjust according to the diameter of the test tube 4, better fixing test tubes 4 of different specifications. At the same time, the elastic deformation of the elastic plate can provide a stable clamping force, ensuring that the test tube 4 will not loosen during transportation and ensuring the safety of the sample.

[0035] In a specific implementation of this utility model, the worker places the bracket 2 entirely into the housing 11 of the transfer box 1. At this time, the bracket 2 is slidably connected to the transfer box 1, and multiple springs 14 between the bracket 2 and the bottom surface of the transfer box 1 support the bracket 2. Then, the worker sequentially passes the test tube 4 containing the liquid sample through the corresponding positioning holes 331 of the first positioning plate 32 and the second positioning plate 33 of the placement rack 3, so that the bottom of the test tube 4 is embedded in the groove 311. During this process, the elastic claws 34 on the inner edge of the corresponding positioning holes 331 abut tightly against the outer wall of the test tube 4 due to their own elasticity, thereby fixing the test tube 4. Next, place the rack 3 inside the tray 2 to complete the placement of the test tubes 4, and then close the lid 12, ensuring that the cushioning sponge 15 on the side of the lid 12 closest to the box body 11 abuts against the top of the handle 23. During transport, if bumps or vibrations occur, multiple springs 14 will absorb and disperse energy through their elastic deformation, reducing the impact force on the tray 2. At the same time, the cushioning sponge 15 will also absorb energy through its own deformation, further cushioning the tray 2 and the rack 3. If any test tube 4 leaks, the liquid sample will flow out of the tray 2 through multiple vertically penetrating leakage holes 24 on the bottom surface of the tray 2, preventing accumulation inside the tray 2 and contamination of other test tubes 4 and samples.

[0036] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
