Description

Technical Field

[0001] This utility model relates to the field of chemical experimental instrument technology, specifically a dustproof pipette rack with a rotating function. Background Technology

[0002] A pipette stand is a device specifically designed for storing pipettes. It has a dustproof function to protect the pipettes from dust contamination.

[0003] In existing technologies, pipette racks contain various reagents, making it difficult to accurately remove pipettes during routine operations, leading to measurement and experimental errors. Furthermore, most pipette racks on the market lack dust protection, and even those with dust protection may not be able to accurately remove the required reagents, resulting in errors in experimental and measurement data. Therefore, we propose a dustproof pipette rack with a rotating function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof pipette holder with a rotating function to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a dustproof pipette holder with a rotating function, including a protective barrel. The upper end of the protective barrel has a first circular hole. A first turntable is rotatably connected to the inner wall of the protective barrel. The upper end of the first turntable has multiple annularly arranged second circular holes. A circular rod is fixedly connected to the upper end of the first turntable. The upper end of the circular rod is rotatably connected to the inner top surface of the protective barrel. A second turntable is rotatably connected to the inner wall of the protective barrel. The upper end of the second turntable has multiple annularly arranged third circular holes. Multiple sets of annularly arranged limiting rods are fixedly connected to the lower end of the first turntable. A tray is slidably connected to the surface of each of the multiple sets of limiting rods. A pipette is placed on the upper end of the tray. The lower end of the circular rod passes through the upper ends of the first turntable and the second turntable and extends to the lower part of the second turntable. A first bevel gear is fixedly connected to the lower end of the circular rod. A second bevel gear is meshed with the surface of the first bevel gear. A rotating rod is fixedly connected to the right end of the second bevel gear. A support plate is fixedly connected to the inner wall of the protective barrel. An electric push rod is fixedly connected to the upper surface of the support plate.

[0006] Preferably, the output end of the electric push rod is fixedly connected to a support circular plate, the diameter of which is smaller than the diameter of the tray.

[0007] Preferably, the lower ends of the multiple sets of limiting rods are all fixedly connected to limiting blocks, and the diameter of the limiting blocks is larger than the diameter of the limiting rods.

[0008] Preferably, the other end of the rotating rod penetrates the inner wall of the protective barrel and extends to the outside, and a knob is fixedly connected to the other end of the rotating rod.

[0009] Preferably, a button is fixedly connected to the surface of the protective barrel, and the button is electrically connected to the electric push rod.

[0010] Preferably, the pipette matches the second circular hole, the diameter of the pipette is smaller than the diameter of the third circular hole, and the diameter of the pipette is smaller than the diameter of the tray.

[0011] Preferably, the diameter of the third circular hole is larger than the diameter of the second circular hole, and the diameter of the third circular hole is larger than the diameter of the tray.

[0012] Preferably, the tray is positioned above the electric push rod.

[0013] This utility model provides an improved dustproof pipette holder with a rotating function, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model involves rotating a knob and driving the second bevel gear and the first bevel gear to rotate via a rotating rod. Then, a round rod drives the first turntable and the second turntable to rotate, moving the pipette to be removed to below the first round hole. This facilitates the management of the pipette to be removed and prevents errors in experimental data caused by taking the wrong pipette during use.

[0015] Secondly, this utility model allows the pipette to be positioned below the first circular hole by rotating the knob. Then, the electric push rod is activated to move the support plate upward, causing the tray to move upward and move the pipette through the first circular hole to the top of the protective container. The pipette can then be removed for the experiment. This not only avoids the mistake of taking the wrong pipette but also prevents the liquid inside the pipette from coming into contact with the outside and causing contamination.

Detailed Implementation

[0022] 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.

[0023] This utility model provides an improved dustproof pipette holder with a rotating function. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 3 As shown, a dustproof pipette holder with a rotating function includes a protective container 1. A first circular hole 2 is formed at the upper end of the protective container 1. A first turntable 3 is rotatably connected to the inner wall of the protective container 1. Multiple annular second circular holes 4 are formed at the upper end of the first turntable 3. A circular rod 7 is fixedly connected to the upper end of the first turntable 3, and the upper end of the circular rod 7 is rotatably connected to the inner top surface of the protective container 1. A second turntable 5 is rotatably connected to the inner wall of the protective container 1. Multiple annular third circular holes 6 are formed at the upper end of the second turntable 5. Multiple sets of rings are fixedly connected to the lower end of the first turntable 3. The limiting rod 8 is shaped and has a tray 9 slidably connected to its surface. A pipette 10 is placed on the upper end of the tray 9. The lower end of the round rod 7 passes through the upper ends of the first turntable 3 and the second turntable 5 and extends to the lower end of the second turntable 5. The lower end of the round rod 7 is fixedly connected to the first bevel gear 11. The surface of the first bevel gear 11 is meshed with the second bevel gear 12. The right end of the second bevel gear 12 is fixedly connected to the rotating rod 13. The inner wall of the protective barrel 1 is fixedly connected to the support plate 14. The upper surface of the support plate 14 is fixedly connected to the electric push rod 15.

[0025] Furthermore, the output end of the electric push rod 15 is fixedly connected to a support circular plate 16. The diameter of the support circular plate 16 is smaller than the diameter of the tray 9. The electric push rod 15 drives the support circular plate 16 to move, so that the support circular plate 16 contacts the tray 9 and drives the pipette 10 to move upward and through the first circular hole 2, so that the pipette 10 can be easily removed.

[0026] Furthermore, the lower ends of multiple sets of limiting rods 8 are all fixedly connected to limiting blocks 17. The diameter of the limiting blocks 17 is larger than the diameter of the limiting rods 8. The limiting blocks 17 limit the tray 9 to prevent it from falling off when it moves to the bottom.

[0027] Furthermore, the other end of the rotating rod 13 penetrates the inner wall of the protective barrel 1 and extends to the outside. A knob 18 is fixedly connected to the other end of the rotating rod 13. When the knob 18 is rotated, the internal tray 9 can be moved.

[0028] Furthermore, a button 19 is fixedly connected to the surface of the protective barrel 1. The button 19 is electrically connected to the electric push rod 15. By pressing the button 19, the electric push rod 15 can be started to work.

[0029] Furthermore, the pipette 10 is matched with the second circular hole 4, the diameter of the pipette 10 is smaller than the diameter of the third circular hole 6, and the diameter of the pipette 10 is smaller than the diameter of the tray 9. The displacement of the tray 9 facilitates the removal of the pipette 10 through the first circular hole 2.

[0030] Furthermore, the diameter of the third circular hole 6 is larger than the diameter of the second circular hole 4, and the diameter of the third circular hole 6 is larger than the diameter of the tray 9. During use, the tray 9 can be moved below the second circular hole 4 to facilitate the removal of the pipette 10.

[0031] Furthermore, the tray 9 is located above the electric push rod 15. The activation of 15 causes the tray 9 to move upward, making it easier to remove the pipette 10.

[0032] Working principle: First, when in use, the pipette 10 is placed into the protective container 1 through the first round hole 2. At this time, the pipette 10 passes through the second round hole 4 and the third round hole 6 and is placed on the tray 9. The limiting rod 8 limits the pipette 10 to prevent it from shaking inside the protective container 1 and causing the liquid inside the pipette 10 to spill. When it is necessary to remove the pipette 10, the knob 18 can be rotated to drive the second bevel gear 12 and the first bevel gear 11 to rotate. The round rod 7 drives the first turntable 3 and the second turntable 5 to rotate so that the pipette 10 to be removed is rotated to below the first round hole 2. At this time, the button 19 is pressed to start the electric push rod 15. The output end of the electric push rod 15 drives the support plate 16 to move upward and drives the pipette 10 on the tray 9 to move upward until the upper part of the pipette 10 moves to the outside of the protective container 1, making it convenient for the staff to remove the pipette 10.

[0033] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
