Description

Technical Field

[0001] The embodiments of this utility model belong to the field of medical auxiliary equipment technology, and more specifically, relate to a novel eight-tube support. Background Technology

[0002] During centrifugation, the samples in the eight-tube bundle will separate due to centrifugal force. To prevent the eight-tube bundle from moving or tipping over during centrifugation, which could lead to sample mixing or leakage, a placement rack provides necessary support and fixation. The eight-tube placement rack is one of the essential devices that provides support and placement space for the eight-tube bundle. It has slots that are the same shape as the eight-tube bundle but slightly larger in size, providing placement space for the eight-tube bundle and achieving vertical support for the eight-tube bundle.

[0003] During centrifugation, the eight tubes may become tightly stuck to the rack due to centrifugal force, making separation difficult. Prying the eight tubes apart one by one is not only time-consuming and laborious, but also increases the operational risk.

[0004] During the forced separation of the eight-tube bundle, improper operation may cause the nucleic acid sample inside the tube to slosh out, or the cap of the eight-tube bundle may be accidentally opened, thereby contaminating the operator's gloves or the surrounding environment, which poses a threat to the accuracy and safety of the experiment.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] A new type of eight-tube rack, including as follows Figures 1-5 As shown, in this embodiment of the utility model, an inner frame assembly 1 is included, an outer frame assembly 2 is movably mounted on the upper part of the inner frame assembly 1, and an ejector assembly 3 is movably disposed between the inner frame assembly 1 and the outer frame assembly 2.

[0029] The inner shelf assembly 1 includes an inner shelf plate 11, with a limiting groove 112 on one side of the inner shelf plate 11. The outer shelf assembly 2 includes an outer shelf plate 21, with a fixing groove 212 on one side of the outer shelf plate 21. An ejection assembly 3 is installed between the limiting groove 112 and the fixing groove 212.

[0030] The ejector assembly 3 includes a rotating column 31, a support rod 32, a sleeve 33, a connecting rod 34, and a limiting sleeve 35. The top end of the support rod 32 is fixedly installed inside the rotating column 31. The sleeve 33 is fitted onto the outside of the support rod 32. A spiral groove 331 is provided on the outside of the sleeve 33. A pin 321 is fixedly installed on one side of the support rod 32. The pin 321 is slidably disposed inside the spiral groove 331 by the rotation of the support rod 32. The connecting rod 34 is fixedly installed at the bottom of the support rod 32. A limiting ring 341 is fixedly installed in the middle of the connecting rod 34. A spring 342 is fixedly installed at the bottom of the limiting ring 341. The spring 342 is fitted into the middle of the connecting rod 34. The limiting sleeve 35 is fitted onto the outside of the connecting rod 34. The top end of the connecting rod 34 is inserted into the limiting groove 112. The rotating column 31 is movably installed inside the fixed groove 212.

[0031] In this embodiment, the inner shelf assembly 1 is installed in a suitable position to ensure its stability. The outer shelf assembly 2 is movably installed on the upper part of the inner shelf assembly 1, allowing the two to move relative to each other. The ejector assembly 3 is installed between the limiting groove 112 and the fixing groove 212, ensuring that the rotating column 31 is movably installed inside the fixing groove 212. The top end of the connecting rod 34 is inserted into the limiting groove 112. The eight connecting tubes are placed in a suitable position on the inner shelf plate 11, ensuring that they are stably supported. The entire placement rack, including the inner shelf assembly 1, the outer shelf assembly 2, and the eight connecting tubes, is placed in a centrifuge for processing. After centrifugation, rotate the rotating column 31 to make the support rod 32 rotate inside the sleeve 33. The pin 321 slides inside the spiral groove 331. The support rod 32 compresses the spring 342, thereby pushing the connecting rod 34 inside the sleeve 33 to move downward. The bottom of the connecting rod 34 pushes the eight-tube connector out of the inner plate 11, making it easy to remove the eight-tube connector. By rotating the rotating column 31 in the opposite direction, the spring 342 is reset. The reset force of the spring 342 pulls the connecting rod 34 back to its original position, and at the same time resets the outer frame assembly 2. The placement rack is then ready for the next experiment.

[0032] The design of the ejector component 3 allows for easy ejection of the eight-tube bundle from the rack without the need for individual manipulation, significantly improving separation efficiency. The ejector component 3 also reduces the risk of sample spillage due to forced separation and accidental opening of the tube caps, thus lowering operational risks. The movable arrangement between the inner rack component 1 and the outer rack component 2, along with the stable support of the ejector component 3, enhances the stability of the rack, ensuring that the eight-tube bundle does not move or tip over during centrifugation. The rack's simple and straightforward design facilitates disassembly and cleaning, making it convenient for researchers to maintain. By reducing operational errors and contamination risks, this rack helps improve experimental accuracy and provides more reliable support for molecular biology experiments.

[0033] Specifically, L-shaped limiters 351 are fixedly installed on the left and right sides of the bottom of the limit sleeve 35, the top of the L-shaped limiters 351 is fixedly installed with the inner layer plate 11, and a hole cylinder 352 is opened in the middle of the bottom of the limit sleeve 35, and the connecting rod 34 is movably inserted into the inside of the hole cylinder 352.

[0034] In this embodiment, the limiting sleeve 35 is located between the inner layer plate 11 and the outer frame assembly 2, and is used to fix and support the connecting rod 34, ensuring that the connecting rod 34 can maintain the correct position and posture when the eight connecting tubes are ejected. The top of the L-shaped limiting 351 is fixedly installed with the inner layer plate 11, providing additional stability and support. By connecting the bottom of the L-shaped limiting 351 with the limiting sleeve 35, a stable support structure is formed to prevent the connecting rod 34 from shifting or tilting during movement. The orifice 352 is a cylindrical channel opened in the middle of the bottom of the limiting sleeve 35. The connecting rod 34 is movably inserted into the inside of the orifice 352, so that the connecting rod 34 can move freely in the orifice 352, while being restricted by the orifice 352 to prevent it from moving excessively or detaching.

[0035] Specifically, the bottom of the spiral groove 331 is provided with a groove 332 for engaging the pin 321, and a bearing sleeve 311 is sleeved on the outside of the rotating column 31. The bearing sleeve 311 is fixedly installed in the inner wall of the fixed groove 212.

[0036] In this embodiment, when the rotating column 31 rotates, the pin 321 on the support rod 32 slides within the spiral groove 331, allowing the support rod 32 to move along the path of the spiral groove 331, thereby driving the connecting rod 34 to move up and down. The groove 332 is an opening at the bottom of the spiral groove 331 for engaging the pin 321. When the pin 321 slides to the bottom of the spiral groove 331, it engages in the groove 332, ensuring the stability and accuracy of the pin 321 during rotation and preventing the pin 321 from falling off or becoming misaligned. The bearing sleeve 311 is an annular component fitted onto the outside of the rotating column 31 and fixedly installed in the inner wall of the fixing groove 212, providing a stable support and rotation platform for the rotating column 31. The use of the bearing sleeve 311 reduces the friction between the rotating column 31 and the fixing groove 212, making the rotation smoother and less strenuous.

[0037] Specifically, the inner layer plate 11 has a first hole plate 111 on its surface, and the outer layer plate 21 has a second hole plate 211 on its surface. The diameter of the first hole plate 111 is smaller than that of the second hole plate 211.

[0038] In this embodiment, by designing the aperture of the first perforated plate 111 to be smaller, the tight support of the first perforated plate 111 helps to prevent the eight tubes from falling off or being damaged due to vibration during centrifugation. This allows for more efficient use of space, enabling more second perforated plates 211 to be adapted to the top of the eight tubes, thus ensuring the stability of the entire placement rack during the ejection process.

[0039] Specifically, limiting side plates 12 are fixedly installed on both sides of the upper surface of the inner layer plate 11, and limiting slot plates 22 are fixedly installed on both sides of the lower surface of the outer layer plate 21. The limiting side plates 12 are movably inserted into the inside of the limiting slot plates 22.

[0040] In this embodiment, the limiting side plate 12 is a plate-like structure fixedly installed on both sides of the upper surface of the inner layer plate 11, restricting the horizontal movement of the inner layer plate 11 and ensuring that the inner layer plate 11 and its eight connecting tubes will not fall off or shift due to vibration or external force during centrifugation or transportation. The limiting slot plate 22 is a plate-like structure fixedly installed on both sides of the lower surface of the outer layer plate 21, and has a slot inside that matches the limiting side plate 12. The slot design allows the limiting side plate 12 to be inserted in the movable state, thereby achieving relative fixation between the inner layer plate 11 and the outer layer plate 21. When it is necessary to install the inner layer plate 11 onto the outer layer plate 21, the experimenter only needs to align the limiting side plate 12 with the slot of the limiting slot plate 22 and gently push it in. The combination of the limiting side plate 12 and the limiting slot plate 22 ensures the relative stability between the inner layer plate 11 and the outer layer plate 21 and reduces the risk of displacement caused by vibration or external force.

[0041] Specifically, the outer wall of the rotating column 31 is provided with an anti-slip sleeve.

[0042] In this embodiment, the anti-slip sleeve is a ring-shaped structure set on the outer wall of the rotating column 31. It is usually made of a material with rubber anti-slip properties to increase the friction on the surface of the rotating column 31 and prevent the rotating column 31 from accidentally falling off or being rotated improperly due to the experimenter slipping during the rotation.

[0043] Specifically, the diameter of spring 342 is larger than the diameter of the tube 352.

[0044] In this embodiment, the diameter of the spring 342 is larger than the diameter of the orifice 352, which means that the spring 342 cannot pass directly through the orifice 352 when it is not subjected to external force. This ensures that the spring 342 can maintain a certain tension during the ejection process, thereby providing a stable ejection force.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
