Description

Technical Field

[0001] This utility model relates to the technical field of biological experimental instruments, and in particular to a storage device for biological test tubes. Background Technology

[0002] Test tubes play a crucial role in biological experiments, their multiple uses making these experiments more precise and efficient. Test tubes can be used to collect and preserve various biological samples, such as cells, bacteria, blood, and urine. Researchers can use test tubes to provide a suitable growth environment for cells and observe processes such as cell growth, division, and metabolism. In biological experiments, test tubes are also commonly used to culture microorganisms such as bacteria and fungi. Test tubes can also be used to conduct various biochemical reactions, such as enzymatic reactions and protein synthesis. Furthermore, test tubes can be used for sample filtration and centrifugation.

[0003] Currently, in biological experiments, test tubes are usually stored on test tube racks, exposed to the air, and are easily contaminated by bacteria. Test tubes placed inside a box are inconvenient to retrieve, and when one test tube is retrieved, other test tubes are easily exposed to the air, causing contamination. It is also inconvenient to open and close the box lid repeatedly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution:

[0005] A storage device for biological test tubes includes a box and a sealing plate. A plurality of placement holes are linearly arranged on the box. One side of the sealing plate is rotatably connected to the box via a fixed rotating shaft. The sealing plate is rotated to cover the linearly arranged placement holes.

[0006] The movable clamping rod and the fixed clamping plate are symmetrically installed in the placement hole. The fixed clamping plate is fixedly connected to the inner wall of the placement hole. The movable clamping rod slides along the diameter direction of the placement hole. Several transmission components are set on the box body corresponding to the movable clamping rod. The movable clamping rod and the rotating shaft are connected through the transmission components. The rotating shaft is driven to rotate through the rotating sealing plate. The sliding of the movable clamping rod is controlled by the transmission components.

[0007] The movable clamping rod includes a clamping plate, an elastic telescopic rod, and a control rod. The tail end of the clamping plate is slidably sleeved on the front end of the elastic telescopic rod. The rear end of the elastic telescopic rod is connected to the transmission assembly. The control rod is fixedly installed on the extended end of the elastic telescopic rod. The transmission assembly drives the elastic telescopic rod and the clamping plate to move closer to the fixed clamping plate. A control component is rotatably set on the housing at the position corresponding to the control rod. By rotating the control component, the control rod is driven to extend or retract the extended end of the elastic telescopic rod.

[0008] The box body has a collection channel that is wider at the top and narrower at the bottom below the placement hole, and several sliding channels are opened in the box body corresponding to the placement hole. The upper part of the sliding channels is connected to the placement hole, and the lower part is connected to the upper end of the collection channel. The bottom side of the box body has an outlet that is connected to the lower end of the collection channel.

[0009] Furthermore, the inner walls of the placement hole, sliding channel, collection channel, and outlet are all equipped with ultraviolet lamps, and the sealing plate is also equipped with several ultraviolet lamps corresponding to the placement hole.

[0010] Furthermore, the control component includes a cam, a connecting shaft, and a rotating plate. The two ends of the connecting shaft are fixedly connected to the cam and the rotating plate, respectively. By rotating the rotating plate, the cam rotates and pushes against the control rod to move, thereby causing the extended end of the elastic telescopic rod to retract.

[0011] Furthermore, the transmission assembly includes a rack, a lead screw, and two gears. The rack is slidably mounted inside the housing, and the lead screw is rotatably mounted inside the housing. The tail end of the elastic telescopic rod is threaded onto the lead screw. The two gears are respectively fixedly mounted on the tail end of the lead screw and the rotating shaft, and both gears mesh with the rack. The rotation of the rotating shaft drives the gears on the rotating shaft to rotate, controlling the rack to slide. The sliding of the rack drives the gears at the tail end of the lead screw to rotate, thereby driving the lead screw to rotate and causing the elastic telescopic rod to slide.

[0012] Furthermore, the rear end of the clamping plate is slidably sleeved on the extended end of the elastic telescopic rod, and a bolt is provided at the rear end of the clamping plate. Tightening the bolt restricts the sliding of the clamping plate on the elastic telescopic rod.

[0013] Furthermore, a cover plate is rotatably installed at the bottom of the box to cover the outlet.

[0014] Furthermore, a one-way plate is rotatably installed below the collection channel. One end of the one-way plate is rotatably connected to the inner wall of the collection channel, and the rotation of the one-way plate is controlled by setting an elastic element.

[0015] Furthermore, the rear of the sealing plate is rotatably connected to the housing via a fixed mounting rotating shaft, and several magnetic strips are fixedly installed on the four sides of the sealing plate. The sealing plate is magnetically attracted to the housing via the magnetic strips, covering the placement hole.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This invention features a series of linearly arranged placement holes on the box body. Moving clamping rods and fixed clamping plates are symmetrically installed within these holes. The elastic telescopic rods of the fixed and moving clamping plates initially hold the test tubes within the placement holes. Rotating a sealing plate mounted on the box body rotates the rotating shaft, driving a transmission assembly to control the sliding of the elastic telescopic rods of the moving clamping rods, causing the clamping plates to move towards the fixed clamping plates, thus clamping the test tubes and preventing collisions and damage during transport. A converging channel, wider at the top and narrower at the bottom, is created below the placement holes within the box body, and corresponding... Several sliding channels are provided, connecting the placement holes and the collection channels. An outlet is also provided on the bottom side of the box, connecting to the collection channels. When retrieving a test tube, the control component corresponding to the placement hole on the box is rotated, causing the extended end of the elastic telescopic rod to retract. This causes the clamping plate to release its grip on the test tube, which falls into the sliding channel, passes through the collection channel, and slides to the outlet. This eliminates the need to open the upper sealing plate, reducing the chance of contamination. Ultraviolet lamps are installed on the inner walls of the placement holes, sliding channels, collection channels, and outlet to sterilize the test tubes and ensure a sterile environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figure 1-5 A storage device for biological test tubes includes a housing 1 and a sealing plate 2. The housing 1 has a plurality of linearly arranged placement holes 101. One side of the sealing plate 2 is rotatably connected to the housing 1 via a fixed rotating shaft 8, allowing the sealing plate 2 to cover the linearly arranged placement holes 101. Moving clamping rods 5 and fixed clamping plates 6 are symmetrically installed within each placement hole 101. The fixed clamping plates 6 are fixedly connected to the inner wall of the placement hole 101. The moving clamping rods 5 slide along the diameter of the placement hole 101. A plurality of transmission components are provided on the housing 1 corresponding to the moving clamping rods 5, allowing transmission... The movable clamping rod 5 and the rotating shaft 8 are connected by a component. The rotating shaft 8 is driven to rotate by the rotating sealing plate 2, and the sliding of the movable clamping rod 5 is controlled by the transmission component. The movable clamping rod 5 includes a clamping plate 501, an elastic telescopic rod 502 and a control rod 503. The tail end of the clamping plate 501 is slidably sleeved on the front end of the elastic telescopic rod 502. The rear end of the elastic telescopic rod 502 is connected to the transmission component. The control rod 503 is fixedly installed on the extended end of the elastic telescopic rod 502. The transmission component drives the elastic telescopic rod 502 and the clamping plate 501 to move closer to the fixed clamping plate 6.

[0026] In this embodiment, the transmission assembly includes a rack 10, a lead screw 11, and two gears 9. The rack 10 is slidably installed inside the housing 1, and the lead screw 11 is rotatably installed inside the housing 1. The tail end of the elastic telescopic rod 502 is threaded onto the lead screw 11. The two gears 9 are respectively fixedly installed on the tail end of the lead screw 11 and the rotating shaft 8, and both gears 9 mesh with the rack 10. The rotation of the rotating shaft 8 drives the gears 9 on the rotating shaft 8 to rotate, controlling the rack 10 to slide. The sliding of the rack 10 drives the gears 9 at the tail end of the lead screw 11 to rotate, thereby driving the lead screw 11 to rotate and causing the elastic telescopic rod 502 to slide.

[0027] In this embodiment, several placement holes 101 are linearly arranged on the housing 1. Movable clamping rods 5 and fixed clamping plates 6 are symmetrically installed in the placement holes 101. The test tubes in the placement holes 101 can be initially clamped by the elastic telescopic rods 502 of the fixed clamping plate 6 and the movable clamping plate. By rotating and closing the sealing plate 2 installed on the housing 1, the rotating shaft 8 is driven to rotate, and the transmission component is driven to control the sliding of the elastic telescopic rods 502 of the movable clamping rods 5, so that the clamping plate 501 moves towards the fixed clamping plate 6, thereby clamping the test tubes and preventing the test tubes from colliding and being damaged during transportation.

[0028] Example 2:

[0029] Please see Figure 1-5 According to Embodiment 1, a control component 4 is rotatably installed on the housing 1 at the position corresponding to the control rod 503. By rotating the control component 4, the control rod 503 is driven to extend or retract the extended end of the elastic telescopic rod 502. The control component 4 includes a cam, a connecting shaft, and a rotating plate. The two ends of the connecting shaft are fixedly connected to the cam and the rotating plate, respectively. By rotating the rotating plate, the cam rotates and moves against the control rod 503, causing the extended end of the elastic telescopic rod 502 to retract, thereby causing the clamping plate 501 to release the clamping of the test tube.

[0030] Example 3:

[0031] Please see Figure 1-5 According to embodiments 1-2, the rear end of the clamping plate 501 is slidably sleeved on the extended end of the elastic telescopic rod 502, and a bolt is provided at the rear end of the clamping plate 501. By tightening the bolt, the sliding of the clamping plate 501 on the elastic telescopic rod 502 is restricted. The distance between the clamping plate 501 and the fixed clamping plate 6 can be adjusted by the sliding of the clamping plate 501, thereby adapting to test tubes of different diameters.

[0032] Example 4:

[0033] Please see Figure 1-5 According to embodiments 1-3, a collection channel 103 with a wider top and a narrower bottom is opened below the placement hole 101 in the box body 1, and several sliding channels 102 are opened in the box body 1 corresponding to the placement hole 101. The upper part of the sliding channel 102 is connected to the placement hole 101, and the lower part is connected to the upper end of the collection channel 103. An outlet 104 is opened on the bottom side of the box body 1, and the outlet 104 is connected to the lower end of the collection channel 103.

[0034] When retrieving the test tube, by rotating the control component 4 corresponding to the placement hole 101 on the housing 1, the extended end of the elastic telescopic rod 502 is retracted, thereby causing the clamping plate 501 to release the clamping plate and the test tube to fall into the sliding channel 102, pass through the collecting channel 103, and slide to the retrieval outlet 104. Thus, the test tube can be retrieved without opening the sealing plate 2 above, reducing the chance of the test tube being contaminated.

[0035] Example 5:

[0036] Please see Figure 1-5 According to embodiments 1-4, the inner walls of the placement hole 101, the sliding channel 102, the collecting channel 103, and the outlet 104 are all equipped with ultraviolet lamps 7. The sealing plate 2 is also equipped with several ultraviolet lamps 7 corresponding to the placement hole 101, which can sterilize the test tube and the sliding channel 102, the collecting channel 103, and the outlet 104 to ensure a sterile environment for the test tube.

[0037] Example 6:

[0038] Please see Figure 1-5 According to embodiments 1-4, a cover plate 3 is rotatably installed below the box body 1, covering the outlet 104. A one-way plate 12 is rotatably installed below the collecting channel 103. One end of the one-way plate 12 is rotatably connected to the inner wall of the collecting channel 103, and the rotation of the one-way plate 12 is controlled by setting an elastic element. When the test tube slides out from below the collecting channel 103, it pushes the one-way plate 12 to rotate and open. After the test tube passes through, the one-way plate 12 rotates under the action of the elastic element to block the bottom of the collecting channel 103.
