Description

Technical Field

[0001] This utility model relates to the field of centrifugal experimental equipment technology, and in particular to a centrifuge tube holder that is easy to clean. Background Technology

[0002] Centrifuge tubes are laboratory instruments primarily used in centrifuges to hold substances for centrifugation. Centrifuge tubes are generally made of plastic and come in various types depending on the material. They typically have good sealing properties to prevent sample leakage or contamination during centrifugation. Due to the significant centrifugal force generated, centrifuge tubes need to have sufficient pressure resistance to prevent breakage during high-speed rotation. For centrifuge tubes containing chemical reagents or biological samples, the material must have good corrosion resistance to ensure sample purity and integrity. To facilitate observation of sample separation after centrifugation, centrifuge tubes usually have good transparency. Centrifuge tubes come in various sizes, including different capacities, lengths, diameters, and bottom shapes, to meet different experimental needs. Centrifuge tube holders, also known as centrifuge tube racks or centrifuge tube boxes, are essential laboratory equipment for storing and protecting centrifuge tubes. They are mainly made of materials such as plastic, plexiglass, silicone, or stainless steel, and are used to safely and orderly store centrifuge tubes of various sizes, protecting them from damage and ensuring their stability during storage and transportation. They also facilitate quick access and return of centrifuge tubes by laboratory personnel.

[0003] To address this, Chinese patent application CN207981245U discloses a centrifuge tube support, which consists of two side uprights, an upper plate, a lower plate, and a plate. The side uprights are vertically positioned on both sides, while the upper and lower plates are horizontally placed above and below the side uprights, respectively. Rectangular grooves are provided on the inner sides of the side uprights. The plate is disposed inside the upper plate, lower plate, and side uprights, and has a first circular hole. This utility model has a simple structure and can satisfy the fixing of a large number of centrifuge tubes of various types.

[0004] While current centrifuge tube supports can generally meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of centrifuge tube holders being unable to accommodate multiple types of centrifuge tubes: Centrifuge tubes are divided into various models in terms of volume, diameter and height, depending on the volume of the target sample obtained from different biological samples. At the same time, in some experiments, as the sample volume increases or decreases, it may be necessary to replace centrifuge tubes of different capacities. Centrifuge tube holders need to be able to hold multiple types of centrifuge tubes at the same time.

[0006] 2. The problem of difficulty in cleaning centrifuge tube holders: Centrifuge tubes are often used in experiments to hold various biological or chemical samples. These samples may contain different microorganisms, proteins, DNA and other substances. Centrifuge tube holders need to be cleaned after each use to avoid residual samples or contaminants from contaminating new samples in the next experiment. However, the numerous gaps in centrifuge tube holders make cleaning difficult. Utility Model Content

[0007] The purpose of this invention is to provide a centrifuge tube holder that is easy to clean, in order to solve the shortcomings of existing centrifuge tube holders that are difficult to adapt to various types of centrifuge tubes and are difficult to clean conveniently.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a centrifuge tube support that is easy to clean, including support legs;

[0009] The bottom of the support leg is bonded with an anti-slip pad, the top of the support leg is engaged with a base, and the top of the base is engaged with a lifting structure.

[0010] The top of the lifting structure is engaged with a support plate, the top of the support plate is provided with a perforated plane, the bottom of the perforated plane is provided with a disassembly structure, and the inside of the perforated plane is provided with a fixing structure.

[0011] The fixing structure includes a large socket, a medium socket, a small socket, a rubber ring, and a marking plate. The large sockets are evenly distributed inside the perforated plane. A medium socket is provided on one side of the large socket. Rubber rings are engaged on the inner side of each large socket. The marking plate is integrally formed on the top of the perforated plane.

[0012] In use, first adjust the height of the outer and inner lifting rods according to the height of the centrifuge tubes to be placed. Rotate the outer lifting rod to move the limiting block inside the outer lifting rod into the lifting groove and slide it up and down. After sliding to the appropriate height, rotate it left and right to move the limiting block into the limiting groove for fixation. Next, align the locking rings on the outer side of the mounting rods on the outer and inner lifting rods with the mounting holes opened on the base, support plate, and perforated surface for snap-fit ​​installation. Finally, install the support feet on the bottom of the base and it is ready for use. Place the centrifuge tubes into the appropriate insertion holes for use.

[0013] Furthermore, a locking block is provided at the top of the support leg, and a locking groove is provided at the bottom of the base. The support leg and the base are connected by a locking mechanism, which facilitates quick assembly and disassembly of the support leg.

[0014] Furthermore, handles are fixedly installed on both sides of the base, and the handles are symmetrically distributed about the central axis of the base, so that users can move the centrifuge tube support without touching the main body of the support, and it is also easier to pick it up.

[0015] Furthermore, the small-sized insertion holes are located inside the perforated plane, and these small-sized insertion holes are evenly distributed inside the perforated plane, allowing various types of centrifuge tubes to be placed stably and as neatly as possible.

[0016] Furthermore, the lifting structure includes an outer lifting rod, an inner lifting rod, a lifting groove, a limiting groove, and a limiting block. The outer lifting rod is engaged with the bottom end of the perforated plane, and the inner lifting rod is installed inside the outer lifting rod. The outer side of the inner lifting rod has a lifting groove, and one side of the lifting groove has a limiting groove. The inner side of the outer lifting rod is integrally formed with a limiting block, allowing the user to adjust the height between the base and the support plate, as well as between the support plate and the perforated plane, according to the height of the centrifuge tube.

[0017] Furthermore, the outer diameter of the limiting block is smaller than the inner diameter of the lifting groove, and the limiting block and the lifting groove are slidably connected. When the limiting block is rotated into the lifting groove, the overall height of the outer lifting rod and the inner lifting rod can be changed.

[0018] Furthermore, the disassembly and assembly structure includes a mounting hole, a mounting rod, a locking ring, and a locking groove. The mounting hole is opened at the bottom end of the perforated plane. The mounting rod is set at the top end of the outer lifting rod and the bottom end of the inner lifting rod. The outer side of the mounting rod is integrally formed with a locking ring, and the inner side of the mounting hole is provided with a locking groove. The various components are connected by locking. Only by disassembling the various components can a thorough cleaning be performed.

[0019] This utility model provides a centrifuge tube holder that is easy to clean. Its advantages include: multiple large, medium, and small insertion holes are evenly distributed inside the perforated plane and support plate, with smaller holes also provided at corresponding positions on the base. This allows users to select the appropriate hole size based on the thickness of the centrifuge tubes, ensuring more stable placement. Rubber rings are installed inside the large, medium, and small insertion holes, and a marking plate is placed at the top of each perforated plane. The rubber rings protect the centrifuge tubes from damage when they collide with the holder and ensure stability when moving the holder. The marking plate has a frosted surface, facilitating the marking of each centrifuge tube and preventing misuse. This achieves the goal of accommodating various centrifuge tube sizes.

[0020] By modularizing the entire centrifuge tube holder, mounting rods are provided for the legs, outer lifting rod, and inner lifting rod. Corresponding mounting holes are provided for the base, support plate, and perforated surface. The locking grooves on the inside of the mounting holes and the locking rings on the outside of the mounting rods are matched to each other. The simple locking method facilitates quick assembly and disassembly of the centrifuge tube holder. At the same time, the components that come into direct contact with the centrifuge tubes, such as the base, support plate, and perforated surface, are all integrally molded, which greatly reduces the occurrence of cleaning dead corners. After use, each component can be disassembled for thorough cleaning, thus achieving the goal of convenient cleaning of the centrifuge tube holder. Attached Figure Description
