Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a centrifuge tube holder that is easy to pick up and put down. Background Technology

[0002] Centrifuge tubes are common laboratory consumables, primarily used to hold samples for centrifugation and to facilitate solid-liquid separation and liquid-liquid separation in centrifuges. They are mostly made of polypropylene or polycarbonate, possessing properties such as acid and alkali resistance and resistance to centrifugal force; some can be sterilized at high temperatures for reuse. Centrifuge tubes come in a wide range of sizes, from microtubes of a few milliliters to large-capacity tubes of hundreds of milliliters, and feature various bottom types such as pointed, round, and flat bottoms to suit different centrifugation scenarios.

[0003] Currently, most centrifuge tube racks used in laboratories are traditional fixed-layer structures. These racks have a fixed shelf spacing, making them unsuitable for different sizes of centrifuge tubes. When tubes of different diameters are mixed together, the sorting effect is poor, and it's difficult to quickly identify the required sample. Furthermore, the layered design makes it inconvenient to retrieve tubes from the lower layers, requiring bending over or reaching into the rack. This process greatly increases the risk of collisions with surrounding tubes, potentially causing damage, sample leakage, and impacting experimental progress and operational safety. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a centrifuge tube shelf that is easy to pick up and put down, which allows for good classification and placement of centrifuge tubes and makes them less likely to collide with each other when being picked up.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a centrifuge tube shelf that is easy to pick up and put down, comprising:

[0006] The base has several legs fixedly installed on its bottom surface;

[0007] A turntable is rotatably connected above the base, with an elevation seat fixed in the center above it and several handles fixed on the side wall.

[0008] The placement rack has two parts, which are fixedly installed on the upper edge of the turntable and on the upper base, respectively. The diameter of the placement rack fixed on the upper base is smaller than the diameter of the placement rack fixed on the turntable. The placement rack includes a lower ring and an upper ring. The lower ring and the upper ring are provided with a number of positioning grooves and positioning holes at equal intervals, and the positioning grooves and positioning holes are aligned vertically. A protective rod is connected between the lower ring and the upper ring at the edge of the positioning grooves and positioning holes.

[0009] Furthermore, the support legs are evenly distributed along the edge of the bottom surface of the base, and an anti-slip pad is fixedly provided on the bottom surface.

[0010] Furthermore, a rotating shaft is rotatably connected at the center of the base, and the center of the bottom surface of the turntable is fixedly connected to the upper end of the rotating shaft.

[0011] Furthermore, a plurality of arc-shaped guide blocks are fixedly provided at equal intervals on the bottom edge of the turntable, and a guide ring groove matching the arc-shaped guide blocks is provided on the base, and the arc-shaped guide blocks are slidably disposed in the guide ring groove.

[0012] Furthermore, the grip bar is provided at equal intervals around the side wall of the turntable, and the extended end is integrally formed with a spherical end.

[0013] Furthermore, the two placement racks are coaxially arranged and coaxial with the rotating shaft.

[0014] Furthermore, there are no fewer than two protective rods on the edges of the same group of positioning grooves and positioning holes.

[0015] Furthermore, the placement rack is provided with label slots that correspond one-to-one with the positioning slots.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the dual placement racks are coaxial and layered in diameter. The inner placement rack is heightened by the riser, which can distinguish centrifuge tubes of different specifications or batches. With the label slot, sample information can be accurately marked, making the classification clear and easy to identify, and avoiding mixed placement. The positioning grooves and positioning holes of the upper and lower rings of the placement rack are precisely aligned, and the protective rod limits the centrifuge tubes from multiple directions, ensuring that each centrifuge tube is independent and stable, and preventing tipping and collision. The turntable can rotate smoothly in all directions, so there is no need to move the whole centrifuge tube when picking up centrifuge tubes in different positions. With the layered placement, the target centrifuge tube can be accurately positioned, which greatly reduces the probability of contact and collision with surrounding tubes during the handling process, taking into account both classification and storage safety.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 2 A centrifuge tube shelf that is easy to pick up and put down includes: a base 1, with a plurality of legs 2 fixedly provided on the bottom surface. The legs 2 are evenly distributed along the bottom edge of the base 1. An anti-slip pad is fixedly provided on the bottom surface to ensure the overall stability of the shelf and avoid tilting on one side. The anti-slip pad can increase the friction with the placement table and prevent the shelf from sliding when picking up and putting down centrifuge tubes.

[0024] Combined with appendix Figure 1 Appendix Figure 4 A turntable 3 is rotatably connected above a base 1. A rotating shaft 11 is rotatably connected to the center of the base 1. The center of the bottom surface of the turntable 3 is fixedly connected to the upper end of the rotating shaft 11. The rotating shaft 11 provides stable rotational support for the turntable 3, ensuring that the turntable 3 will not deviate during rotation. The connection structure is simple, allowing the turntable 3 to rotate smoothly in all directions, facilitating the placement and removal of centrifuge tubes in different positions. Several arc-shaped guide blocks 12 are fixedly arranged at equal intervals along the bottom edge of the turntable 3. The base 1 has guide ring grooves matching the arc-shaped guide blocks 12. The arc-shaped guide blocks 12 slide within the guide ring grooves, providing a limiting and guiding function for the rotation of the turntable 3. This effectively distributes the load-bearing pressure of the rotating shaft 11, improving the overall structural stability of the turntable 3 during rotation and preventing wobbling.

[0025] Combined with appendix Figure 1 Appendix Figure 3 A heightening seat 4 is fixedly installed at the center of the upper part of the turntable 3, and several grips 5 are fixedly installed on the side wall. Several grips 5 are evenly arranged around the side wall of the turntable 3, and the extended end is integrally formed with a spherical end 13, which makes it convenient for users to hold and rotate the turntable 3 from different positions. The spherical end 13 can prevent the sharp ends of the grips 5 from scratching the hands, while improving the comfort of holding and making the operation safer.

[0026] Combined with appendix Figure 1 Appendix Figure 3 The centrifuge tubes are provided in two, one fixed on the upper edge of the turntable 3 and the other on the upper support 4. The diameter of the centrifuge tube fixed on the upper support 4 is smaller than that of the centrifuge tube fixed on the turntable 3. The two centrifuge tubes are coaxially arranged and coaxial with the rotating shaft 11. This ensures that when the turntable 3 rotates, the centrifuge tubes on the centrifuge tubes all rotate around the same axis. This can prevent the centrifuge tubes from colliding due to eccentric rotation, and at the same time make the overall structure of the centrifuge tubes more regular and the space utilization rate higher.

[0027] Combined with appendix Figure 1 Appendix Figure 4The placement rack includes a lower ring 6 and an upper ring 7. The lower ring 6 and the upper ring 7 are each provided with a plurality of equidistant positioning grooves 8 and positioning holes 9, and the positioning grooves 8 and positioning holes 9 are aligned vertically. A protective rod 10 is connected between the lower ring 6 and the upper ring 7 at the edges of the positioning grooves 8 and positioning holes 9. There are at least two protective rods 10 at the edges of the same group of positioning grooves 8 and positioning holes 9, which can limit and protect the centrifuge tubes from multiple angles; effectively preventing the centrifuge tubes from tipping over during the rotation of the turntable 3 or during handling, thus improving the stability of the centrifuge tubes.

[0028] Combined with appendix Figure 1 Appendix Figure 3 The placement rack is equipped with label slots 14 that correspond one-to-one with the positioning slots 8, which makes it easy for users to mark and distinguish samples in different centrifuge tubes, quickly identify sample information of each centrifuge tube, avoid confusion, and improve the convenience and accuracy of experimental operations.

[0029] The specific implementation of this utility model is as follows: The shelf is placed on a flat tabletop. The support feet 2 and anti-slip pads on the bottom of the base 1 ensure overall stability and prevent slippage. According to the specifications of the centrifuge tubes, they are placed in batches and categories into the positioning slots 8 and positioning holes 9 of the two-layer shelf above the turntable 3. The protective rod 10 will limit the movement from the side to prevent the centrifuge tubes from tipping over or shaking. Then, the sample information is filled into the corresponding label slots 14 to complete the classification and labeling.

[0030] When you need to take out centrifuge tubes, you can hold the handle 5 on the side wall of the heightening seat 4 (the ball end 13 can improve the grip comfort), which will drive the turntable 3 to rotate around the shaft 11. The arc-shaped guide block 12 will slide in the guide ring groove to ensure that the turntable 3 rotates smoothly and does not deviate. You can accurately take out the target centrifuge tube by turning it in front of you without moving the whole equipment.

[0031] After use, return the centrifuge tubes to their original positions and double-check the label information to complete the entire operation. This process avoids collisions between centrifuge tubes and makes sorting and retrieval convenient and efficient.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
