Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a quick-clamping pipette tip box. Background Technology

[0002] A pipette is a type of pipette commonly used in laboratories for transferring small or micro-volume liquids. Different sizes of pipettes require different sized tips, and the shapes of pipettes from different manufacturers may vary slightly, but the working principle and operation method are basically the same. Traditionally, pipettes are considered precision instruments, requiring careful handling and storage to prevent damage and avoid affecting their volume. This is especially true for the storage of pipette tips. Most existing pipette tip boxes only store pipette tips, and each box can only accommodate one type of tip. When there are many different types of pipette tips, this becomes inconvenient, requiring the replacement of different tip boxes. Furthermore, storing pipette tips does not allow for sterilization, limiting their functionality.

[0003] To address the aforementioned technical issues, the prior art CN216024992U provides a pipette tip holder. This device facilitates the storage of pipette tips and can clamp and fix pipette tips of different sizes. After the pipette tips are placed, they can be rotated. Combined with the ultraviolet disinfection lamp, this achieves the disinfection of the pipette tips. The rotation ensures that the ultraviolet disinfection lamp disinfects the pipette tips evenly, guaranteeing a good disinfection and sterilization effect.

[0004] However, certain technical issues may arise during its use. For example, when using the device, operators need to manipulate multiple positioning and clamping components on the clamping ring one by one to clamp the pipette tip with the elastic pads inside the positioning and clamping components. However, this makes the operation of the device cumbersome and complicated, and causes inconvenience to the fixation of the pipette tip. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a quick-clamping pipette tip holder that allows staff to easily secure pipette tips while simultaneously improving the disinfection and sterilization effect of the tips.

[0006] This utility model is achieved through the following technical solution: a quick-clamping pipette tip holder is provided, including a cylindrical box body, an ultraviolet disinfection lamp fixed on the inner side wall of the cylindrical box body, and a sealing door fixedly installed on the front of the cylindrical box body. A rotating motor is fixed on the bottom wall of the cylindrical box body by a support frame. A clamping ring is fixed on the outer side wall of the output shaft of the rotating motor by a connecting rod. Four positioning clamping components are arranged circumferentially on the clamping ring. An internal gear ring is sleeved on the clamping ring. A first gear is arranged between two of the positioning clamping components, which is rotatably connected to the outer side wall of the clamping ring and meshes with the internal gear ring. A transmission mechanism is meshed on the internal gear ring to move the elastic pad inside the positioning clamping component toward the axis of the clamping ring.

[0007] In use, this invention comprises a cylindrical box, an ultraviolet disinfection lamp fixed to the inner wall of the cylindrical box, and a sealed door fixed to the front of the cylindrical box. A rotating motor is fixed to the bottom wall of the cylindrical box via a support frame. A clamping ring is fixed to the outer wall of the output shaft of the rotating motor via a connecting rod. Four positioning clamping components are arranged circumferentially on the clamping ring. An internal gear ring is fitted on the clamping ring. A first gear is provided between two positioning clamping components, rotatably connected to the outer wall of the clamping ring and meshing with the internal gear ring. A transmission mechanism meshes with the internal gear ring, causing the elastic pads inside the positioning clamping components to move towards the axis of the clamping ring. During use, the cylindrical box is opened by controlling the sealed door. Then, a pipette tip is placed inside the clamping ring, coaxial with the clamping ring. Finally, one of the first gears is controlled to move along the outer wall of the clamping ring. The internal gear ring rotates, causing one of the first gears to rotate, which in turn drives the other first gears to rotate on the outer wall of the clamping ring. This, in turn, causes the internal gear ring to drive the transmission mechanism that meshes with it, moving the elastic pad inside the positioning clamping assembly toward the axis of the clamping ring and into contact with the pipette tip. In this way, the pipette tip, located inside the clamping ring and coaxial with it, is fixed by the four positioning clamping assemblies. Then, the cylindrical box is closed by controlling the sealing door. After that, the rotating motor and ultraviolet disinfection lamp on the support frame are turned on, so that the output shaft of the rotating motor drives the clamping ring to rotate inside the cylindrical box via the transmission of the connecting rod. This ensures that the ultraviolet disinfection lamp disinfects the pipette tip evenly and improves the disinfection and sterilization effect of the device on the pipette tip. This allows the staff to fix the pipette tip while improving the disinfection and sterilization effect.

[0008] Preferably, the positioning and clamping assembly includes a square support fixed to the outer wall of the clamping ring, an inner liner plate fixedly connected to the inner wall of the square support, a lead screw rotatably mounted on the outer wall of the inner liner plate via a bearing, a sliding plate sleeved on the lead screw, a connecting post between the inner liner plate and the inner wall of the square support, one end of the connecting post extending laterally toward the axis of the clamping ring and passing through the clamping ring, an elastic pad fixed to one end of the connecting post, the other end of the connecting post fixedly connected to the inner wall of the sliding plate, a baffle plate provided on the side of the square support away from the sliding plate, a limiting post fixedly connected to the outer wall of the square support extending laterally toward the axis away from the clamping ring, passing through the sliding plate and fixedly connected to the inner wall of the baffle plate, and a rotating shaft coaxially fixedly connected to the end of the lead screw away from the clamping ring, passing through the baffle plate. The positioning and clamping assembly includes a square support fixed to the outer wall of a clamping ring. An inner liner plate is fixedly connected to the inner wall of the square support. A lead screw is rotatably mounted on the outer wall of the inner liner plate via a bearing. A sliding plate is sleeved on the lead screw. A connecting post is provided between the inner liner plate and the inner wall of the square support. One end of the connecting post extends laterally towards the axis of the clamping ring and passes through the clamping ring. An elastic pad is fixed to one end of the connecting post. The other end of the connecting post is fixedly connected to the inner wall of the sliding plate. A baffle is provided on the side of the square support away from the sliding plate. A limiting post is fixedly connected to the outer wall of the square support, extending laterally towards the axis away from the clamping ring, passing through the sliding plate, and fixedly connected to the inner wall of the baffle. A rotating shaft passing through the baffle is coaxially fixed to the end of the lead screw away from the clamping ring. During use... The internal gear ring drives the transmission mechanism that meshes with it. The transmission mechanism drives the rotating shaft to rotate inside the baffle, thereby causing the lead screw to rotate with the rotating shaft inside the sliding plate and the bearing on the outer wall of the inner liner. At this time, the limiting post passes through the sliding plate and is fixed to the outer wall of the square support and the inner wall of the baffle respectively. Therefore, the sliding plate will not rotate with the lead screw, but will move towards the axis of the clamping ring under the rotation drive of the lead screw. This will drive the connecting post between the inner liner and the inner wall of the square support, and the clamping ring will also move towards the axis of the clamping ring. This will drive the elastic pad fixed at one end of the connecting post to move towards the axis of the clamping ring and contact the pipette tip, thereby fixing the pipette tip located inside the clamping ring and coaxial with the clamping ring.

[0009] Preferably, the transmission mechanism includes a turbine coaxially fixed to the end of the rotating shaft away from the baffle. A worm gear, rotatably connected to the sidewall of the baffle away from the sliding plate, meshes with the turbine. A second gear, meshing with an internal gear ring, is mounted on the worm gear. In use, the rotation of the internal gear ring drives the second gear to rotate, which in turn drives the worm gear to rotate on the sidewall of the baffle away from the sliding plate. This causes the worm gear to drive the turbine gear to rotate. During this process, the rotation of the turbine gear drives the rotating shaft to rotate within the baffle, thus facilitating the internal gear ring's drive of the rotating shaft.

[0010] Preferably, two support plates are fixedly connected to the side wall of the baffle away from the sliding plate, and the inner side walls of the two support plates are rotatably connected to the end of the worm gear. By fixing two support plates to the side wall of the baffle away from the sliding plate, and rotatably connecting the inner side walls of the two support plates to the end of the worm gear, the stability of the worm gear rotation during use can be improved.

[0011] Preferably, a rotating rod is provided in the inner hole of the first gear, and a vertical plate fixedly connected to the outer wall of the clamping ring is provided at the end of the rotating rod. The first gear and the outer wall of the clamping ring are rotatably connected through the rotating rod and the vertical plate. By providing a rotating rod in the inner hole of the first gear, and a vertical plate fixedly connected to the outer wall of the clamping ring at the end of the rotating rod, the first gear and the outer wall of the clamping ring are rotatably connected through the rotating rod and the vertical plate, the stability of the rotation of the first gear during use can be improved.

[0012] Preferably, a rotating handle is provided on the side wall of one of the upright plates away from the first gear, for driving the rotating rod to rotate between the two upright plates. By providing a rotating handle on the side wall of one of the upright plates away from the first gear, the operator can easily drive the rotating rod to rotate between the two upright plates, thereby driving the first gear to rotate.

[0013] Preferably, a base plate is fixedly connected to the bottom of the cylindrical box. By fixing the base plate to the bottom of the cylindrical box, it is convenient for workers to place the cylindrical box at the work site.

[0014] The beneficial effects of this utility model are as follows: By setting a cylindrical box body, an ultraviolet disinfection lamp fixed to the inner wall of the cylindrical box body, and a sealed door fixed to the front of the cylindrical box body, a rotating motor is fixed to the bottom wall of the cylindrical box body via a support frame. A clamping ring is fixed to the outer wall of the output shaft of the rotating motor via a connecting rod. Four positioning clamping components are arranged circumferentially on the clamping ring. An internal gear ring is fitted on the clamping ring. A first gear is arranged between two positioning clamping components, rotatably connected to the outer wall of the clamping ring and meshing with the internal gear ring. A transmission mechanism meshes on the internal gear ring, causing the elastic pad inside the positioning clamping component to move towards the axis of the clamping ring. In use, the cylindrical box body needs to be opened by controlling the sealed door. Then, by placing the pipette tip inside the clamping ring and making the pipette tip coaxial with the clamping ring, one of the first gears is controlled to move on the outer wall of the clamping ring. The internal gear ring rotates, causing one of the first gears to rotate, which in turn drives the other first gears to rotate on the outer wall of the clamping ring. This, in turn, causes the internal gear ring to drive the transmission mechanism that meshes with it, moving the elastic pad inside the positioning clamping assembly toward the axis of the clamping ring and into contact with the pipette tip. In this way, the pipette tip, located inside the clamping ring and coaxial with it, is fixed by the four positioning clamping assemblies. Then, the cylindrical box is closed by controlling the sealing door. After that, the rotating motor and ultraviolet disinfection lamp on the support frame are turned on, so that the output shaft of the rotating motor drives the clamping ring to rotate inside the cylindrical box via the transmission of the connecting rod. This ensures that the ultraviolet disinfection lamp disinfects the pipette tip evenly and improves the disinfection and sterilization effect of the device on the pipette tip. This allows the staff to fix the pipette tip while improving the disinfection and sterilization effect. Attached Figure Description

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figures 1-7 The quick-clamping pipette tip holder of this utility model includes a cylindrical box body 2, an ultraviolet disinfection lamp 5 fixed on the inner side wall of the cylindrical box body 2, and a sealing door 1 fixedly installed on the front of the cylindrical box body 2. A rotating motor 4 is fixed on the inner bottom wall of the cylindrical box body 2 by a support frame 7. A clamping ring 8 is fixed on the outer side wall of the output shaft of the rotating motor 4 by a connecting rod 6. Four positioning clamping components are arranged circumferentially on the clamping ring 8. An internal gear ring 13 is sleeved on the clamping ring 8. A first gear 10 is arranged between two of the positioning clamping components, which is rotatably connected to the outer side wall of the clamping ring 8 and meshes with the internal gear ring 13. A transmission mechanism is meshed on the internal gear ring 13 to move the elastic pad 9 inside the positioning clamping component toward the axis of the clamping ring 8.

[0018] The positioning and clamping assembly includes a square support 23 fixed to the outer wall of the clamping ring 8. An inner liner 26 is fixedly connected to the inner wall of the square support 23. A lead screw 20 is rotatably mounted on the outer wall of the inner liner 26 via a bearing 27. A sliding plate 21 is sleeved on the lead screw 20. A connecting post 14 is provided between the inner liner 26 and the inner wall of the square support 23. One end of the connecting post 14 extends laterally toward the axis of the clamping ring 8 and passes through the clamping ring 8. An elastic pad 9 is fixed to one end of the connecting post 14. The other end of the connecting post 14 is fixedly connected to the inner wall of the sliding plate 21. A baffle 19 is provided on the side of the square support 23 away from the sliding plate 21. A limiting post 22, extending laterally toward the axis away from the clamping ring 8, passes through the sliding plate 21 and is fixedly connected to the inner wall of the baffle 19, is fixedly connected to the outer wall of the square support 23. A rotating shaft 18, passing through the baffle 19, is coaxially fixed to the end of the lead screw 20 away from the clamping ring 8. When in use, the internal gear ring 13 drives the transmission mechanism that meshes with it. The transmission mechanism drives the rotating shaft 18 to rotate within the baffle 19, thereby causing the lead screw 20 to rotate within the sliding plate 21 and the bearing 27 on the outer wall of the inner liner 26 along with the rotating shaft 18. At this time, the limiting post 22 passes through the sliding plate 21 and is fixed to the outer wall of the square support 23 and the inner wall of the baffle 19 respectively. Therefore, the sliding plate 21 will not rotate with the lead screw 20, but will move towards the axis of the clamping ring 8 under the rotation drive of the lead screw 20. This will drive the connecting post 14 between the inner wall of the inner liner 26 and the inner wall of the square support 23, and the clamping ring 8 to move towards the axis of the clamping ring 8. This will drive the elastic pad 9 fixed at one end of the connecting post 14 to move towards the axis of the clamping ring 8 and contact the pipette tip, thereby fixing the pipette tip located inside the clamping ring 8 and coaxial with the clamping ring 8. The transmission mechanism includes a turbine 17 coaxially fixed to the end of the rotating shaft 18 away from the baffle 19. A worm gear 25 meshes with the turbine 17 and is rotatably connected to the side wall of the baffle 19 away from the sliding plate 21. A second gear 16 is sleeved on the worm gear 25 and meshes with an internal gear ring 13. During use, the rotation of the internal gear ring 13 drives the second gear 16 to rotate, which in turn drives the worm gear 25 to rotate on the side wall of the baffle 19 away from the sliding plate 21. This causes the worm gear 25 to drive the turbine 17 to rotate. In this process, the rotation of the turbine 17 drives the rotating shaft 18 to rotate within the baffle 19, facilitating the internal gear ring 13's drive of the rotating shaft 18. Two support plates 15 are fixed to the side wall of the baffle 19 away from the sliding plate 21, and the inner walls of the two support plates 15 are rotatably connected to the end of the worm gear 25. The support plates 15 improve the stability of the worm gear 25's rotation during use. By providing a rotating rod 24 in the inner hole of the first gear 10, and a vertical plate 12 fixedly connected to the outer wall of the clamping ring 8 at the end of the rotating rod 24, the first gear 10 and the outer wall of the clamping ring 8 are rotatably connected through the rotating rod 24 and the vertical plate 12. The stability of the rotation of the first gear 10 during use can be improved by using the rotating rod 24 and the vertical plate 12.A rotating handle 11 is provided on the side wall of one of the upright plates 12 away from the first gear 10, allowing the rotating rod 24 to rotate between the two upright plates 12. The rotating handle 11 allows the operator to easily drive the rotating rod 24 to rotate between the two upright plates 12, thereby driving the first gear 10 to rotate. A base plate 3 is fixedly connected to the bottom of the cylindrical box 2, allowing the operator to easily place the cylindrical box 2 at the work site.

[0019] Combined with appendix Figure 1-7 The method of using this utility model is as follows: First, the cylindrical box 2 is placed on the work site using the base plate 3. Then, the cylindrical box 2 is opened by controlling the sealing door 1. Next, the pipette tip is placed inside the clamping ring 8 and made coaxial with the clamping ring 8. Then, by rotating the handle 11, one of the rotating rods 24 is driven to rotate between the two upright plates 12, which drives one of the first gears 10 to rotate on the outer wall of the clamping ring 8. This causes the internal gear ring 13 to rotate with one of the first gears 10, thereby driving the other first gears 10 to rotate. The other first gears 10 drive the rotating rod 24 connected to it to rotate on the upright plate 12 on the outer wall of the clamping ring 8. Then, the rotation of the internal gear ring 13 drives the second gear 16 meshing with it to rotate, and drives the worm gear 25 to rotate on the support plate 15 on the side wall of the baffle 19 away from the sliding plate 21. This causes the worm gear 25 to drive the meshing turbine 17 to rotate. During this process, the rotation of the turbine 17 will drive the shaft 18 to rotate within the baffle 19, thereby causing the lead screw 20 to rotate within the sliding plate 21 and the bearing 27 on the outer wall of the inner liner 26 along with the shaft 18. At this time, the limiting post 22 passes through the sliding plate 21 and is fixed to the outer wall of the square support 23 and the inner wall of the baffle 19 respectively. Therefore, the sliding plate 21 will not rotate with the lead screw 20, but will move towards the axis of the clamping ring 8 under the drive of the rotation of the lead screw 20, and drive the connecting post 14 between the inner liner 26 and the inner wall of the square support 23 and the clamping ring 8 to clamp. The ring 8 moves along its axis, thereby driving the elastic pad 9 fixed at one end of the connecting column 14 to move towards the axis of the clamping ring 8 and contact the pipette tip. In this way, the pipette tip, which is located inside the clamping ring 8 and coaxial with the clamping ring 8, is fixed by the four positioning clamping components. Then, the cylindrical box 2 is closed by controlling the sealing door 1. After that, the rotating motor 4 on the support frame 7 and the ultraviolet disinfection lamp 5 are turned on, so that the output shaft of the rotating motor 4 drives the clamping ring 8 to rotate inside the cylindrical box 2 through the transmission of the connecting rod 6. This ensures that the ultraviolet disinfection lamp 5 disinfects the pipette tip evenly and improves the disinfection and sterilization effect of the device on the pipette tip.
