Description

Technical Field

[0001] This utility model belongs to the field of high-pressure sterilization technology, and in particular relates to a high-pressure sterilization device for sterilizing pipette tips. Background Technology

[0002] With the rapid development of the life sciences and biopharmaceutical industry, pipette tips, as core consumables used in laboratories for precise liquid transfer, have their sterility directly affecting the accuracy and reliability of experimental results. Especially in scenarios with stringent requirements for sterile environments, such as cell culture, microbial detection, and molecular diagnostics, sterilized pipette tips have become a key prerequisite for ensuring the validity of experimental data. Therefore, efficient and stable autoclaving equipment is needed to sterilize pipette tips to thoroughly kill any bacteria, viruses, spores, and other microorganisms that may remain on or inside the tip, thus avoiding the risk of cross-contamination.

[0003] However, existing high-pressure sterilization equipment lacks a structural design that allows for easy control of the contact and distance of supporting components from the ground. This makes it difficult to flexibly adapt to different usage scenarios. Additional tools or complex operations are required to switch between the fixed and mobile states of the equipment, making it difficult to ensure the structural stability of the equipment in various states. Consequently, this affects the convenience and safety of sterilization operations. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure sterilization device for sterilizing pipette tips. By setting up a support and fixing part, it solves the problem that existing high-pressure sterilization devices lack a structural design that allows for convenient control of the support parts' contact with and distance from the ground during use. This makes it difficult to flexibly adapt to different usage scenarios, requiring additional tools or complex operations to switch between the fixed and mobile states of the device. It also makes it difficult to ensure the structural stability of the device in various states, thus affecting the convenience and safety of sterilization operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a high-pressure sterilization device for sterilizing pipette tips, comprising a support plate 1 and a plurality of rectangular rods fixedly connected to the bottom of the support plate 1. A second support plate is fixedly connected to the bottom of the plurality of rectangular rods, and a high-pressure sterilization device is fixedly connected to the top of the support plate 1. The device further includes: a support fixing part mounted on the second support plate; a movable part disposed between the first and second support plates; the support fixing part includes a fixing component mounted on the second support plate; and a driving component mounted between the first and second support plates; the fixing component includes a cross plate disposed between the first and second support plates, and a plurality of supporting legs extend through the second support plate. The legs are slidably connected to the support plate 2. Each of the support legs is fixedly connected to a cylindrical rod 1. Each of the cross plates is fixedly connected to a cylindrical rod 2. Each of the cylindrical rod 1 and cylindrical rod 2 is hinged with a hinge rod. A transmission component is provided at the top of the support plate 2. There are four support legs, four cylindrical rods 1, and four cylindrical rods 2. The transmission component includes several rectangular plates fixedly connected to the top of the support plate 2. Each of the rectangular plates has a cylindrical rod 3 fixedly connected to one side of each rectangular plate. Each of the cylindrical rod 3 has a transmission rod hinged to its outer wall. Each of the transmission rods has two telescopic rods fixedly connected to it. Each telescopic rod is fixedly connected to one of the cylindrical rods 2. All telescopic rods are in a semi-compressed state.

[0006] Furthermore, the movable part includes a support assembly mounted on the second support plate; and a movable assembly mounted on the support assembly; the movable assembly is located below the second support plate.

[0007] Furthermore, the drive assembly includes a hydraulic cylinder fixedly connected to the bottom of the support plate one, the output shaft of the hydraulic cylinder being fixedly connected to the cross plate, and a plurality of support rods being fixedly connected between the support plate one and the support plate two, each of the support rods penetrating the cross plate and each of the support rods being slidably connected to the cross plate; four support rods are provided, arranged in a circumferential array.

[0008] Furthermore, the support assembly includes connecting rods that pass through the left and rear sides of the cross plate respectively, both connecting rods are fixedly connected to the cross plate, and hexagonal support rods are fixedly connected to the front and rear sides of both connecting rods. Several hexagonal support rods pass through the second support plate and are slidably connected to the second support plate. Four hexagonal support rods are provided.

[0009] Furthermore, the movable component includes triangular fixing blocks that are fixedly connected to the bottom of several hexagonal support rods, and each of the several triangular fixing blocks is provided with a movable component; there are four triangular fixing blocks, all located below the second support plate, and each movable component includes a rotating rod that passes through the several triangular fixing blocks, and the several rotating rods are rotatably connected to the several triangular fixing blocks respectively, and each of the several rotating rods has a movable wheel fixedly connected to its outer wall; the several movable wheels are located inside the several triangular fixing blocks respectively.

[0010] Furthermore, the high-pressure sterilization equipment in this device adopts the LS-35HD vertical high-pressure sterilizer. Its working principle is based on pressure steam sterilization technology. Steam is generated by heating water inside the sterilizer, while the sterilization chamber is sealed to prevent steam leakage. This gradually creates a high-pressure environment within the chamber. Under high pressure, the boiling point of the steam increases, raising the temperature inside the chamber to a sterilization threshold exceeding 100℃, typically reaching 121℃-138℃, and maintaining this temperature for a certain period. During this process, the high-temperature, high-pressure steam can fully penetrate the surface and internal crevices of the items to be sterilized, such as instruments, dressings, and utensils. By destroying the proteins, nucleic acids, and other bioactive substances of microorganisms, it thoroughly kills bacteria, viruses, spores, and other microorganisms, ultimately achieving aseptic treatment of the items. After sterilization, the equipment automatically releases the steam from the chamber. Once the pressure and temperature drop to a safe range, the sterile items can be removed.

[0011] This utility model has the following beneficial effects: 1. By setting up a support fixing part, after the hydraulic cylinder is started, the hydraulic cylinder drives the cross plate to move upward along several support rods. The cross plate drives the corresponding hinge rods to move through multiple cylindrical rods 2. The upper hinge rods drive multiple transmission rods to rotate on several cylindrical rods 3 through corresponding telescopic rods. Subsequently, these cylindrical rods 3, through the lower telescopic rods, hinge rods and cylindrical rods 1, jointly push multiple support legs to move below the support plate 2. Conversely, by reversing the above process, the support legs can be moved away from the ground. During the movement, the telescopic rods will deform to match the overall movement, which can conveniently control the support legs to contact or move away from the ground, meet the use needs of the equipment in different scenarios, and ensure the structural stability of the equipment when supported or moved. 2. By incorporating a movable section, when several support legs are in contact with the ground, the cross plate moves several hexagonal support rods upward via two connecting rods, thereby causing several moving wheels to detach from the ground. Conversely, when several support legs are away from the ground, the cross plate similarly moves several hexagonal support rods downward via these two connecting rods, pushing several moving wheels into contact with the ground. This achieves alternating ground contact between the support legs and moving wheels, ensuring reliable switching between the "fixed support" and "moving dispatch" states. It also prevents the support legs from scraping the ground during movement, thus extending the service life of equipment components.

[0020] It should be noted that the control of the hydraulic cylinder 221 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control.

The cross plate 211 then drives corresponding hinge rods 215 to move via several cylindrical rods 214. The upper hinge rods 215 then drive several transmission rods 218 to rotate on several cylindrical rods 217 via corresponding telescopic rods 219. These cylindrical rods 217 then push several support legs 212 to move up and down on the support plate 113 via the lower telescopic rods 219, hinge rods 215, and cylindrical rods 213. During this process, the telescopic rods 219 deform, thus better coordinating the movement. The reverse operation described above causes several support legs 212 to move away from the ground. When several support legs 212 are in contact with the ground, the cross plate 211 drives several hexagonal support rods 312 upward through two connecting rods 311, thereby causing several moving wheels 323 to move away from the ground. When several support legs 212 are away from the ground, the cross plate 211 drives several hexagonal support rods 312 downward through two connecting rods 311, causing several moving wheels 323 to contact the ground. Through the above operation process, the autoclave 114 is operated alternately in a fixed and moving manner. When sterilizing pipette tips, the autoclave 114 is opened, and the sterilizing pipette tips are placed into the autoclave 114 to sterilize them.
