Description

Technical Field

[0001] This utility model relates to the field of biological science experimental equipment technology, specifically a sample preservation device for type IV collagen detection. Background Technology

[0002] With the continuous development of bioscience and medical technology, the requirements for sample preservation and testing are becoming increasingly stringent. Especially in the field of type IV collagen testing, the integrity and stability of the sample are crucial to the accuracy of the test results. Therefore, how to effectively preserve and conveniently access samples has become a problem that needs to be solved.

[0003] In existing technologies, sample preservation devices mostly employ traditional fixing methods, such as using screws or clips to secure sample tubes to the device. However, this method is not only cumbersome to operate, but also prone to damaging the sample tubes during sample storage and retrieval, affecting the integrity and stability of the sample. Furthermore, traditional sample preservation devices often require manual insertion into the device during sampling. For samples preserved at low temperatures, this not only increases the risk of hand injury but may also cause discomfort due to direct contact with cold surfaces, affecting operator comfort and work efficiency. To address these issues, some improved sample preservation devices have emerged on the market, but these devices often suffer from complex structures... The inconvenience of operation and high cost of traditional sample preservation methods make them unsuitable for practical applications. Therefore, we need a sample preservation device that can effectively secure sample tubes while simplifying the operation and avoiding direct hand contact. To this end, we propose a sample preservation device for type IV collagen detection. This device achieves effective fixation of the sample tubes through the ingenious combination of a fan-shaped block and a rotating disk, ensuring the stability and integrity of the samples during storage. Furthermore, the device employs a design where the inner box rises with the rotating base, elevating the sample tubes to an easily accessible height, avoiding the need for direct hand contact with the cold surface and preventing discomfort. In addition, this device boasts advantages such as simple structure, convenient operation, and low cost, making it suitable for various samples requiring cryopreservation and providing strong support for bioscience and medical research, including type IV collagen detection.

[0004] The purpose of this invention is to provide a sample preservation device for type IV collagen detection, so as to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a sample preservation device for type IV collagen detection, including a base, a box body rotatably connected to the inner wall of the base, a box cover threadedly connected to the surface of the box body, an inner box rotatably connected to the inner wall of the box body, the lower end of the inner box being fixedly connected to the inner wall of the base, two symmetrically arranged through grooves on the surface of the inner box, two symmetrically arranged sliding rods fixedly connected to the surface of the inner box, two symmetrically arranged sliding grooves on the inner wall of the box body, a central column fixedly connected to the inner wall of the base, the central column rotatably connected to the inner wall of the chassis, a chassis being provided inside the inner box, two symmetrically arranged central gears being sleeved on the surface of the central column, the upper central gear being fixedly connected to the upper end of the central column, and a fixed lifting device being provided inside the inner box.

[0006] Preferably, the fixed lifting device includes two sets of symmetrically arranged half gears. Each set of half gears meshes with the surface of an adjacent central gear. A rotating disk is fixedly connected to the inner wall of each half gear. Multiple symmetrically arranged arc-shaped grooves are formed on the surface of each rotating disk. Multiple symmetrically arranged sector blocks are rotatably connected to the upper end of each rotating disk. A small round rod is fixedly connected to the lower end of each sector block. A support frame is rotatably connected to the lower end of each upper rotating disk. Each support frame is fixedly connected to the upper end of the chassis. Sample tubes are provided on the inner wall of each lower rotating disk and the corresponding upper rotating disk. Multiple sets of symmetrically arranged support rods are fixedly connected to the upper end of the chassis. Two symmetrically arranged telescopic rods are rotatably connected to the side wall of each support rod. Each telescopic rod is rotatably connected to the upper end of an adjacent sector block.

[0007] Preferably, each of the slide bars is sized to match the corresponding slide groove, and each of the slide bars is slidably connected to the inner wall of the corresponding slide groove.

[0008] Preferably, the surface of the central column is provided with two sets of symmetrically arranged strip grooves, and the inner wall of each central gear is fixedly connected with two symmetrically arranged rectangular blocks, which are slidably connected to the inner wall of the corresponding strip groove.

[0009] Preferably, the inner wall of the box has two symmetrically arranged slots, and the surface of the chassis has two symmetrically arranged blocks fixedly connected, each block penetrating the inner wall of the corresponding slot and slidingly connected to the inner wall of the slot.

[0012] This invention provides an improved sample preservation device for type IV collagen detection, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this utility model achieves effective fixation of the sample tube through the ingenious cooperation between the sector block and the rotating disk. When the device is closed, the sector block tightly clamps the sample tube, preventing it from falling off due to shaking or external force. This fixing method not only ensures the stability of the sample tube during storage, but also avoids damage caused by the sample tube colliding with each other.

[0014] Secondly, when it is necessary to remove the sample tube, simply rotate the base and the fan-shaped block will automatically open. At the same time, the inner box will rise with the rotation of the base, lifting the sample tube to a height that is easy to pick up. This design not only simplifies the operation process, but also avoids the need for people to directly reach into the device to pick up the sample tube. Especially for sample tubes that are stored at low temperatures, this design effectively prevents the hands from feeling uncomfortable due to direct contact with the cold surface. In addition, the height of the sample tube also makes the picking process easier and less strenuous, improving work efficiency and user experience. Attached Figure Description

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] This utility model provides an improved sample preservation device for type IV collagen detection. The technical solution of this utility model is as follows:

[0029] like Figure 1 - Figure 9 As shown, a sample preservation device for type IV collagen detection includes a base 1, a box 2 rotatably connected to the inner wall of the base 1, a box cover 3 threadedly connected to the surface of the box 2, an inner box 4 rotatably connected to the inner wall of the box 2, the lower end of the inner box 4 being fixedly connected to the inner wall of the base 1, two symmetrically arranged through grooves 5 opened on the surface of the inner box 4, two symmetrically arranged sliding rods 6 fixedly connected to the surface of the inner box 4, two symmetrically arranged sliding grooves 7 opened on the inner wall of the box 2, a central column 8 fixedly connected to the inner wall of the base 1, the central column 8 being rotatably connected to the inner wall of the base 9, the base 9 being provided inside the inner box 4, two symmetrically arranged central gears 10 being sleeved on the surface of the central column 8, the upper central gear 10 being fixedly connected to the upper end of the central column 8, and a fixed lifting device being provided inside the inner box 4.

[0030] Furthermore, the fixed lifting device includes two sets of symmetrically arranged half gears 11. Each set of half gears 11 meshes with the surface of the adjacent central gear 10. A rotating disk 12 is fixedly connected to the inner wall of each half gear 11. Multiple symmetrically arranged arc-shaped grooves 13 are formed on the surface of each rotating disk 12. Multiple symmetrically arranged sector blocks 14 are rotatably connected to the upper end of each rotating disk 12. A small round rod 15 is fixedly connected to the lower end of each sector block 14. A support frame 16 is rotatably connected to the lower end of each upper rotating disk 12. Each support frame 16 is fixedly connected to the upper end of the chassis 9. Each lower rotating disk 12 is connected to the corresponding upper rotating disk 12. The inner wall of each component is provided with sample tubes 17. The upper end of the base plate 9 is fixedly connected to multiple sets of symmetrically arranged support rods 20. The side wall of each support rod 20 is rotatably connected to two symmetrically arranged telescopic rods 21. Each telescopic rod 21 is rotatably connected to the upper end of the adjacent sector block 14. Through the meshing connection of two sets of symmetrically arranged half gears 11 and the adjacent central gear 10, the stability and synchronization during the rotation process are ensured. The rotatable connection between the telescopic rod 21 and the upper end of the sector block 14 allows the sector block 14 to rotate smoothly on the rotating disk 12. When the sector block 14 is opened, the telescopic rod 21 is shortened. When the sector block 14 rotates to clamp the sample tube 17, the telescopic rod 21 is extended.

[0031] Furthermore, each slide rod 6 is matched with the size of the corresponding slide groove 7, and each slide rod 6 is slidably connected to the inner wall of the corresponding slide groove 7. By sliding the slide rod 6 in the slide groove 7, the inner box 4, which is fixedly connected to the slide rod 6, can move vertically while rotating.

[0032] Furthermore, the surface of the central column 8 is provided with two sets of symmetrically arranged strip grooves. The inner wall of each central gear 10 is fixedly connected with two symmetrically arranged rectangular blocks. The rectangular blocks are slidably connected to the inner wall of the corresponding strip groove. By setting the rectangular blocks and strip grooves, when the central column 8 rotates, the rectangular blocks are stuck in the strip grooves, so that the central gear 10 can rotate together and move up and down on the surface of the central column 8.

[0033] Furthermore, the inner wall of the box 2 has two symmetrically arranged slots 18, and the surface of the base 9 is fixedly connected to two symmetrically arranged blocks 19. Each block 19 passes through the inner wall of the corresponding through groove 5 and is slidably connected to the inner wall of the slot 18. By setting the slots 18 and blocks 19, when the inner box 4 moves upward due to the rotation of the base 1, the inner wall of the through groove 5 lifts the block 19, so that the block 19 of the base 9 slides in the slot 18, thus allowing it to move upward smoothly.

[0034] Furthermore, the lower central gear 10 is rotatably connected to the upper end of the chassis 9, and the lower rotating disk 12 is rotatably connected to the upper end of the chassis 9. When the central column 8 rotates, it drives the lower central gear 10 to rotate as well. Due to the meshing connection between the central gear 10 and the half gear 11, this rotation is further transmitted to the rotating disk 12, causing it to rotate as well. During this process, the chassis 9 does not rotate with the central gear 10, but maintains a relatively stable position. In order to achieve smooth rotation of the central gear 10 and the rotating disk 12, and at the same time ensure the stability of the chassis 9, a rotatable connection between the lower central gear 10 and the upper end of the chassis 9 is specially set. This design allows the central gear 10 to rotate freely on the chassis 9 without being restricted or affected by the chassis 9.

[0035] Furthermore, each small round rod 15 is matched with the size of the corresponding arc groove 13, and each small round rod 15 is slidably connected to the inner wall of the corresponding arc groove 13. The precise matching of the size of the small round rod 15 and the arc groove 13 ensures the accurate positioning of the sector block 14 on the rotating disk 12. When the rotating disk 12 rotates, the small round rod 15 slides along the inner wall of the arc groove 13. This sliding connection restricts the movement direction of the sector block 14 and also ensures its stable movement on the preset path, realizing the function of the sector block 14 opening and clamping the sample tube 17.

[0036] Working principle: In the initial state, all sample tubes 17 are inside the rotating disk 12 and clamped and fixed by the sector block 14. When in use, the sample tubes 17 need to be removed. First, unscrew the box cover 3, then rotate the base 1. The base 1 drives the inner box 4 and the central gear 10 to rotate. The base 9 is locked in the slot 18 by the locking block 19, so it does not rotate with the inner box 4 and the central column 8. The through groove 5 on the surface of the inner box 4 allows the inner box 4 to have a certain rotation space within the locking block 19. When the central column 8 rotates, it drives the upper and lower central gears 10 to rotate together. The upper and lower central gears 10 mesh, causing the corresponding half gears 11 to rotate. The half gears 11 drive the rotating disk 12 to rotate. Through the cooperation of the arc groove 13 and the small round rod 15, the small round rod 15 drives the sector block 14 to move within the arc groove 13, thereby allowing the sector block 14 to move within the rotating disk. Rotate the base 12 at a certain angle and open it. At this time, the fixing of the sector block 14 to the sample tube 17 is released. While the base 1 drives the inner box 4 to rotate, the two sliding rods 6 on the inner box 4 slide in the corresponding sliding grooves 7. The sliding rods 6 drive the inner box 4 to rise in the box body 2. The inner box 4 then moves upward together with the locking block 19 through the through groove 5. Therefore, when the base 1 is rotated, the sector block 14 opens and the fixing of the sample tube 17 is released. The inner box 4 and the base plate 9 raise the rotating disk 12 and the sample tube 17 inside, so that the sample tube 17 can be taken out from the sector block 14. When it is necessary to put the sample tube 17 into the base 1 for storage, put the sample tube 17 into the sector block 14 and rotate the base 1 in the opposite direction. Similarly, the sector block 14 clamps the sample tube 17, the inner box 4 and the base plate 9 descend, so that the sample tube 17 is completely placed in the inner box 4. Then tighten the box cover 3.
