Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a lightweight horizontal rotor structure for a centrifuge. Background Technology

[0002] In practical applications of centrifuges, the weight of the horizontal rotor assembly has always been a critical issue that urgently needs to be addressed. Currently, most horizontal rotor assemblies on the market are quite bulky, mainly because the rotors are mostly made of stainless steel components or galvanized steel parts, and the basket assemblies are also generally heavy.

[0003] Taking the centrifugation of a 10ml blood collection tube at 4000 rpm as an example, the strength requirements for the horizontal rotor assembly are not extremely high under these conditions. However, due to the material and structural design, the existing horizontal rotor assembly is too heavy. This not only increases the overall load on the centrifuge, causing it to consume more energy during operation, but also occupies a lot of space. Therefore, it is necessary to develop a lightweight horizontal rotor structure for centrifuges. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A lightweight horizontal rotor structure for a centrifuge includes a horizontal rotor assembly and a U-shaped basket assembly. The horizontal rotor assembly consists of a horizontal rotor, a horizontal rotor pin, and a retaining spring. The horizontal rotor pin is fixedly connected to the horizontal rotor by the retaining spring.

[0007] The U-shaped hanging basket assembly consists of a hanging basket, a U-shaped hanging basket, and test tubes. The middle part of the U-shaped hanging basket is designed as a hollow structure.

[0013] In a preferred embodiment of the lightweight horizontal rotor structure for a centrifuge described in this utility model, the opening size of the retaining ring is 3mm.

[0014] The beneficial effects of this utility model are: the lightweight horizontal rotor assembly and U-shaped hanging basket assembly make installation, disassembly, and maintenance easier and more convenient, reducing the labor intensity of operators and improving work efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-5 The diagram shows a structural schematic of an embodiment of a lightweight horizontal rotor structure for a centrifuge according to this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed description of a lightweight horizontal rotor structure for a centrifuge.

[0027] A lightweight horizontal rotor structure for a centrifuge includes a horizontal rotor assembly 1 and a U-shaped basket assembly 2. The horizontal rotor assembly 1 consists of a horizontal rotor 1-1, a horizontal rotor pin 1-2, and a retaining ring 1-3. The horizontal rotor 1-1 is designed to be as small as possible in terms of volume while ensuring strength, meeting centrifugal force and centrifugal radius requirements, and avoiding assembly interference. The horizontal rotor pin 1-2 is fixedly connected to the horizontal rotor 1-1 by the retaining ring 1-3.

[0028] The U-shaped hanging basket assembly 2 consists of a hanging basket 2-1, a U-shaped hanging basket 2-2, and test tubes 2-3. The middle part of the U-shaped hanging basket 2-2 is designed as a hollow structure. The hanging basket 2-1 and the U-shaped hanging basket 2-2 are fixedly connected by self-tapping screws, and the test tubes 2-3 are placed in the hanging basket 2-1. Through this structural design, while ensuring that the working requirements of the centrifuge are met, the weight of the entire horizontal rotor structure is reduced as much as possible. At the same time, the reasonable connection method ensures the stability and reliability of the structure, enabling the centrifuge to complete the centrifugation work more efficiently during operation, reducing energy loss and operational inconvenience caused by excessive structural weight. Furthermore, the close cooperation between the various components provides a guarantee for achieving the efficient centrifugation function of the centrifuge.

[0029] Furthermore, the horizontal rotor 1-1 is provided with mounting holes for installation and connection with the centrifuge; the matching screws and mounting holes enable the horizontal rotor 1-1 to be accurately installed on the centrifuge, ensuring the accuracy and stability of the installation.

[0030] Furthermore, the horizontal rotor pin 1-2 is provided with an annular groove, and the retaining spring 1-3 is installed in the annular groove; the annular groove and the retaining spring 1-3 enable the retaining spring 1-3 to firmly fix the horizontal rotor pin 1-2 and the horizontal rotor 1-1 together, which enhances the reliability of the connection and prevents the two from loosening or separating when the centrifuge is running at high speed.

[0031] Furthermore, the hanging basket 2-1 is provided with reinforcing ribs, which are located on the outer side of the hanging basket 2-1. The reinforcing ribs improve the structural strength of the hanging basket 2-1. Although the hanging basket 2-1 is made of relatively lightweight materials, the reinforcement of the reinforcing ribs enables it to withstand the weight of the test tube 2-3 and the force generated during centrifugation, making it less prone to deformation and ensuring the safety and stability of use.

[0032] Furthermore, the inner wall of the U-shaped basket 2-2 is an arc-shaped inner wall, which fits against the outer side of the test tube 2-3; this reduces the shaking of the test tube 2-3 during centrifugation, allowing the sample to be subjected to centrifugal force more evenly, thus improving the centrifugation effect;

[0033] Furthermore, the thread length of the self-tapping screw 3 is 15mm; this thread length design ensures that the self-tapping screw 3 has sufficient connection depth when fixing the hanging basket 2-1 and the U-shaped hanging basket 2-2, ensuring the firmness of the connection and preventing the self-tapping screw 3 from loosening due to vibration or other reasons during the operation of the centrifuge, thereby affecting the stability of the entire U-shaped hanging basket assembly 2.

[0034] Furthermore, the opening size of the retaining ring 1-3 is 3mm; this opening size ensures that the retaining ring 1-3 can be easily installed and removed, and provides sufficient elastic force after installation to tightly fix the horizontal rotor hanging pin 1-2 and the horizontal rotor 1-1 together, thus ensuring the connection stability of the horizontal rotor assembly 1.

[0035] The horizontal rotor 1-1 and the U-shaped suspended platform 2-2 are made of aluminum alloy, which is much lighter than steel for the same volume. While ensuring strength, the horizontal rotor 1-1 is designed to have the smallest possible centrifugal radius and to avoid assembly interference, while the middle part of the U-shaped suspended platform 2-2 is designed to be hollow. Figure 5 The hanging basket 2-1 uses molded plastic parts, resulting in low mass production costs. Two holes are cut at the bottom (see details). Figure 4 To prevent deformation due to excessive wall thickness and to reduce weight, the horizontal rotor 1-1, U-shaped hanging basket 2-2, and hanging basket 2-1 are all lightweight designs, resulting in a significant reduction in total weight.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
