Description

Technical Field

[0001] This utility model relates to the field of magnetic rack technology, and in particular to a magnetic rack for large-volume centrifuge tubes. Background Technology

[0002] Magnetic racks can quickly adsorb magnetic beads and samples onto the test tube wall, thereby achieving efficient separation of the target analyte from other components in the solution. Magnetic racks for large-volume centrifuge tubes play an important role in the laboratory. Their features, such as being designed specifically for large-volume centrifuge tubes, rapid separation, strong magnetism, ease of operation, and wide applicability, make them promising for applications in biomedicine, molecular biology, and other fields.

[0003] Chinese patent CN220352137U discloses a multifunctional magnetic rack. The base has a support column with a hollow cavity, within which a magnet is placed. At least one side wall of the support column has a positioning plate with a positioning hole for horizontally positioning test tubes. An elastic abutment is located on the side of the positioning plate away from the support column, abutting against the side wall of the test tube and pushing it closer to the support column. This invention's elastic abutment is compressible, with one end located within the positioning hole, allowing passive adjustment of the hole's size. This makes it suitable for test tubes of different sizes, improving the versatility of the magnetic rack. Furthermore, by using multiple positioning plates, the separation of magnetic microspheres and liquid within multiple test tubes can be achieved, increasing separation efficiency.

[0004] The above method cannot control the pressure on the test tubes during the clamping process, which can easily lead to damage to the test tubes due to excessive pressure during clamping, reducing the practicality of the magnetic rack for large-volume centrifuge tubes. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic rack for large-volume centrifuge tubes to solve the problems mentioned in the background art.

[0006] To address the above problems, this utility model provides a technical solution:

[0007] A magnetic rack for large-volume centrifuge tubes includes a mounting frame, a protective shell, fixing components, a storage slot, a sensor, a spring, a baffle, and a contact head. The protective shell is fixedly mounted on the top of the mounting frame. Multiple fixing components are provided on the top of the protective shell. Each fixing component has a storage slot on one side, and a sensor is fixedly mounted inside each storage slot. Springs are symmetrically fixedly mounted inside each storage slot. A baffle is fixedly mounted on one side of every two springs, and a contact head is fixedly mounted on the inner side of each baffle.

[0008] As a preferred embodiment of this utility model, a separation component is provided on the top of the protective shell, and multiple transmission lines are fixedly installed on the top of the separation component. A storage battery is fixedly installed inside the protective shell.

[0009] As a preferred embodiment of the present invention, the fixing component includes a placement frame, each placement frame is fixedly installed on one side of the protective shell, and a fixing seat is fixedly installed inside each placement frame.

[0011] As a preferred embodiment of the present invention, the separation component includes a second electric slide rail, which is fixedly installed on one side of the protective housing. A second track block is slidably connected to the outer end of the second electric slide rail, and an L-shaped plate is fixedly installed on one side of the second track block.

The magnetic rod head and the transmission line are fixedly connected.

[0013] The beneficial effects of this utility model are as follows: by setting a fixing component, large-volume centrifuge tubes can be fixed, preventing them from shaking due to magnetic attraction within the large positioning hole. By setting a storage groove, sensor, spring, baffle, and contact head, the sensor and contact head are used to detect during the clamping process, which can prevent the large-volume centrifuge tubes from being damaged by huge pressure. This protects the large-volume centrifuge tubes and improves the practicality of the magnetic frame for large-volume centrifuge tubes. Attached Figure Description

[0028] The separation component 9 includes a second electric slide rail 91. The second electric slide rail 91 and the first electric slide rail 33 are equipped with an electric motor, which is supplied with electrical energy by a power source and converted into mechanical energy to drive the movement of the slide rail. The second electric slide rail 91 is fixedly installed on one side of the protective housing 2. The outer end of the second electric slide rail 91 is slidably connected to a second track block 92. An L-shaped plate 93 is fixedly installed on one side of the second track block 92. Multiple support plates 94 are fixedly installed on one side of each L-shaped plate 93.
