Description

Technical Field

[0001] This utility model relates to the field of eight-tube technology, and in particular to a magnetic frame device for fixing eight-tubes. Background Technology

[0002] The eight-tube consumable consists of eight independent sub-tubes integrated on a common base. Each sub-tube can hold the reaction liquid independently. It is mainly used as a consumable in high-precision biological, medical, and chemical applications. It is usually made of polypropylene (PP) material and falls under the category of medical device management. When using the eight-tube consumable, a magnetic rack is required to facilitate the magnetic separation of the reaction liquid inside the eight-tube consumable, thereby facilitating subsequent operations.

[0003] A PCR eight-tube fixing device with announcement number CN221720794U includes a mounting base with eight evenly arranged insertion holes on its surface. Each insertion hole has an elliptical cylindrical structure and contains a secondary arc plate and a primary arc plate. The primary arc plate is mounted on the inner wall of the mounting base via a telescopic spring. When the experimenter presses the push block, the sliding column moves along the track of the slide groove and hooks into the concave part of the groove. At this time, the telescopic rod remains extended, allowing the connecting rod to drive the secondary arc plate to clamp and fix the eight tubes. The experimenter does not need to continuously apply force to the secondary arc plate. When it is necessary to remove the eight tubes, the push block is pressed again, causing the sliding column to move out of the concave part of the groove. The push block resets under the action of spring B, thereby allowing the telescopic rod to drive the connecting rod to reset the secondary arc plate, releasing the eight tubes. This enhances the stability and versatility of the overall device, facilitating operation by experimenters and laboratory promotion.

[0004] However, the above-mentioned PCR eight-tube fixation device still has the following defects in use: In the use of the above-mentioned existing technology, the experimenter directly inserts the eight tubes into the corresponding sockets. However, in actual use, the above operation is inconvenient to seal them. Therefore, the staff needs to manually seal them, which not only increases the labor intensity of the staff, but also easily contaminates the reaction solution inside the eight tubes, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a magnetic frame fixing eight-tube device to solve the problem mentioned in the background art that the existing magnetic frame fixing eight-tube device does not have a sealing function during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnetic frame fixing eight-tube device, comprising a magnetic frame body, an eight-tube body, insertion holes, and magnets. Insertion holes are evenly provided on both sides of the top of the magnetic frame body, and the eight-tube body is provided inside the insertion holes. Magnets are evenly provided inside the magnetic frame body.

[0007] A sealing mechanism is provided on one side of the main body of the magnetic frame, and adjustment mechanisms are provided on both sides inside the main body of the magnetic frame.

[0008] When using the magnetic frame fixing eight-tube device of this technical solution, the sealing mechanism not only seals the eight-tube body during use, but also initially limits and fixes it, thereby preventing it from moving and improving its practicality.

[0009] Preferably, the sealing mechanism includes a guide rod, which is disposed on one side of the magnetic frame body. A sealing plate is sleeved on the outer side of the guide rod, and a pipe cap is uniformly fixed at the bottom end of the sealing plate. A fixing spring is uniformly wound on the outer side of the guide rod, and one end of the fixing spring is fixedly connected to the sealing plate. A stop block is fixed at the top end of the guide rod, and a sliding groove is provided inside the stop block. A slider is slidably disposed inside the sliding groove, and a limit block is slidably disposed on one side of the stop block.

[0010] Preferably, there are two fixing springs, which are symmetrically distributed and both are in a stretched state on the outside of the guide rod.

[0011] Preferably, there are two sliders, which are symmetrically distributed and both sliders have a T-shaped cross-section.

[0012] Preferably, the adjustment mechanism includes an adjustment block, which is disposed inside the magnetic frame body. A guide block is fixed at the bottom end of the adjustment block, a push block is disposed on one side of the adjustment block, a return spring is fixed on one side of the adjustment block, and an adjustment rod is disposed on the other side of the adjustment block, with one end of the adjustment rod extending to the outside of the magnetic frame body.

[0013] Preferably, the adjustment mechanism includes an adjustment block, which is disposed inside the magnetic frame body. A guide block is fixed at the bottom end of the adjustment block, a push block is disposed on one side of the adjustment block, a return spring is fixed on one side of the adjustment block, and an adjustment rod is disposed on the other side of the adjustment block, with one end of the adjustment rod extending to the outside of the magnetic frame body.

[0014] Preferably, the guide blocks are provided in two sets, each set of the guide blocks has two blocks, and the outer side of both sets of the guide blocks is provided with guide grooves, and both guide grooves are provided inside the magnetic frame body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the magnetic frame fixing eight-tube device not only has a sealing function, but also facilitates the quick removal of the eight-tube body from the magnetic frame body.

[0016] By pushing the limiting block away from the cover plate under the action of the slider and the slide groove, the limiting block is released from the limiting of the cover plate. Then, the fixing spring is reset and drives the cover plate to move downward until one side of the cover plate and one side of the eight-tube body are in contact with each other, so that the tube cap is inserted into the interior of the eight-tube body. Through the above operation, not only can the eight-tube body be automatically sealed, thus avoiding the contamination of the reaction liquid inside the eight-tube body, but the eight-tube body can also be limited and fixed to prevent it from moving in position, thereby improving its practicality.

[0017] By pressing the adjusting rod, the adjusting block moves horizontally under the action of the guide block and the guide groove, thereby pushing the push block to move upward. Through the above operation, the eight-tube body can be lifted from the magnetic frame body, making it easier for the user to quickly remove the eight-tube body from the magnetic frame body, thus improving its working efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 An embodiment of this utility model is provided: a magnetic frame fixing eight-tube device, including a magnetic frame body 1, an eight-tube body 2, a socket 3, and a magnet 5. The two sides of the top of the magnetic frame body 1 are evenly provided with sockets 3, and the eight-tube body 2 is provided inside the sockets 3. The magnets 5 are evenly provided inside the magnetic frame body 1, and a sealing mechanism 4 is provided on one side of the magnetic frame body 1.

[0027] The sealing mechanism 4 includes a guide rod 401, which is located on one side of the magnetic frame body 1. A sealing plate 405 is sleeved on the outer side of the guide rod 401, and a pipe cap 406 is evenly fixed at the bottom end of the sealing plate 405. A fixing spring 402 is evenly wound on the outer side of the guide rod 401, and one end of the fixing spring 402 is fixedly connected to the sealing plate 405. A stop block 407 is fixed at the top end of the guide rod 401, and a sliding groove 408 is provided inside the stop block 407. A slider 404 is slidably arranged inside the sliding groove 408, and a limit block 403 is slidably arranged on one side of the stop block 407.

[0028] There are two fixed springs 402, which are symmetrically distributed and are both in a stretched state on the outside of the guide rod 401.

[0029] There are two sliders 404, which are symmetrically distributed and both sliders 404 have a T-shaped cross-section.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in use, by pushing the limiting block 403 to release the limiting of the cover plate 405, the pipe cover 406 is inserted into the interior of the eight-pipe body 2 under the action of the fixing spring 402. Through the above operation, not only can the eight-pipe body 2 be covered, but the eight-pipe body 2 can also be limited and fixed, thereby preventing it from moving in position.

[0031] Adjustment mechanisms 6 are provided on both sides inside the main body 1 of the magnetic frame;

[0032] The adjustment mechanism 6 includes an adjustment block 601, which is located inside the magnetic frame body 1. A guide block 605 is fixed to the bottom end of the adjustment block 601. A push block 602 is provided on one side of the adjustment block 601. A reset spring 604 is fixed on one side of the adjustment block 601. An adjustment rod 603 is provided on the other side of the adjustment block 601, and one end of the adjustment rod 603 extends to the outside of the magnetic frame body 1.

[0033] There are two sets of adjustment blocks 601, and each set has two adjustment blocks 601, and the two sets of adjustment blocks 601 are symmetrically distributed.

[0034] Two sets of guide blocks 605 are provided, and each set of guide blocks 605 has two blocks. Guide grooves are provided on the outer side of both sets of guide blocks 605, and both guide grooves are provided inside the magnetic frame body 1.

[0035] Specifically, such as Figure 2 , Figure 4 As shown, during use, by pushing the adjusting rod 603, the push block 602 is lifted up under the action of the adjusting block 601, which makes it easier to lift up the eight-tube body 2 that is attached to the magnetic frame body 1, and then make it easier for the staff to quickly remove the eight-tube body 2 from the magnetic frame body 1, thus facilitating subsequent operations.

[0036] Working principle: In use, the eight-tube body 2 is first inserted into the insertion hole 3, which pushes the limiting block 403 so that the slider 404 is inside the slide groove 408, thereby limiting and guiding the movement of the limiting block 403. When the limiting block 403 moves away from the cover plate 405, the limiting force on the fixing spring 402 disappears, thus restoring its deformation. During the process of the fixing spring 402 restoring its deformation, it drives the cover plate 405 to move downward, thereby causing the tube cap 406 to move downward synchronously until one side of the cover plate 405 and one side of the eight-tube body 2 are in contact with each other, so that the tube cap 406 is inserted into the eight-tube body 2. The above operation facilitates the automatic sealing of the eight-tube body 2, and can also limit and fix the eight-tube body 2, thereby preventing the eight-tube body 2 from moving during use, and thus improving its stability during use.

[0037] Then, the cells, proteins, or nucleic acids in the reaction solution inside the eight-tube body 2 are separated and purified by using magnets 5. After separation and purification, the sealing plate 405 is pulled to make it rise. When the sealing plate 405 moves to a certain position, the limiting block 403 is pushed to limit the sealing plate 405. At the same time, the adjusting rod 603 is pushed to make the adjusting block 601 move horizontally. The horizontal movement of the adjusting block 601 causes the guide block 605 to move synchronously. The guide block 605 limits and guides the moving adjusting block 601 to prevent it from shifting position. The horizontal movement of the adjusting block 601 pushes the push block 602 to rise, so that the push block 602 is pushed out from inside the magnetic frame body 1, and then lifts the eight-tube body 2 that is attached to the magnetic frame body 1. The above operation makes it easy for the staff to quickly remove the eight-tube body 2, which facilitates subsequent operations.
