Description

Technical Field

[0001] The utility model relates to the technical field of laboratory equipment, in particular to a PCR eight-tube placement rack. Background Art

[0002] Octa-tube strips, also known as 8-well tubes or 8-well tube strips, are used for simultaneous gene amplification and quantification of multiple samples in experiments such as PCR and qPCR. They are especially used in biology, chemistry, medical research, and clinical experiments. Octa-tube strips consist of 8 interconnected tubes, usually in one piece. This design is intended to facilitate simultaneous experimental processing of multiple samples.

[0003] During the use of the eight-tube strip, in order to facilitate subsequent retrieval, a placement device will be used to store and place the eight-tube strip, such as Figure 7 As shown, the eight-tube strips will be placed on a storage rack;

[0004] However, in the process of actually storing and placing the eight-strip tubes on the racks, it was found that a single rack could accommodate a limited number of eight-strip tubes. When a laboratory uses a large number of eight-strip tubes, several racks are often needed. Multiple racks not only affect the laboratory space, but also make it difficult for laboratory personnel to observe and take the eight-strip tubes.

Through the engagement and sliding of the movable plate 54 with the limiting groove 531, the placement mechanism 5 can be pushed to slide above 1, so that 5 can be pulled out from above 1, so as to facilitate the placement of the eight-unit tube 6.

[0033] In this embodiment, the assembly mechanism 2 includes an assembly rod 21, a support ring 1 22 and a support ring 23. The assembly rod 21 is arranged on the top surface of the support plate 1. A support assembly is arranged outside the assembly rod 21. The support assembly includes a support ring 1 22 and a support ring 23. The support ring 1 22 and the support ring 23 are engaged and rotated. The support ring 1 22 and the support ring 23 are engaged and slid with the assembly rod 21. Through the assembly rod 21 arranged in the assembly mechanism 2, the placement mechanism 5 can be rotated with the assembly rod 21 as a point, so as to facilitate the adjustment of the posture of the placement mechanism 5 to take and place the eight-unit tube 6. Through the support assembly arranged, the placement mechanism 5 can be assisted to rotate outside the assembly rod 21.

[0034] In this embodiment, the rotating cylinder 55 is engaged and slidably engaged with the assembly rod 21, and the rotating cylinder 55 is rotatably connected with the assembly rod 21; through the engagement and sliding of the rotating cylinder 55 and the assembly rod 21, it is convenient to assemble the placement mechanism 5 on the outside of the assembly rod 21 by the rotating cylinder 55, and then the placement mechanism 5 can be removed and used when needed;

[0035] In this embodiment, the placement mechanism 5 and the pallet 1 have two states: storage and taking.

Through the mutual conversion between the storage and taking states formed by the placement mechanism 5 and the pallet 1, the position of the placement plate 51 can be changed, so as to facilitate the storage and taking of the eight-piece tube 6.

[0036] By means of the movable grooves 53 provided inside the multiple placement trays 51 and the rotation of the rotating cylinder 55 inside the movable plate 54 and the assembly rod 21, the placement tray 51 can be rotated to adjust its position while sliding, thereby making it more convenient for the placement rack to take and store the eight-piece tube 6.

[0037] Embodiment 2

[0038] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0039] In order to make the placement tray 51 more stable when stored, this embodiment provides the following design:

[0040] The fixing mechanism 3 includes a fixing vertical rod 31, a fixing block 32, a mounting column 33 and a fixing magnetic block 34. The fixing vertical rod 31 is fixedly arranged on the side of the end of the support plate 1. The fixing vertical rod 31 is mirror-distributed at the end of the support plate 1. A mounting hole is opened inside the fixing vertical rod 31. A fixing component is arranged inside the fixing vertical rod 31. The fixing component includes a fixing block 32, a mounting column 33 and a fixing magnetic block 34. A mounting column 33 is arranged at the end of the fixing block 32. The mounting column 33 is threadedly connected to the mounting hole. A fixing magnetic block 34 is arranged on the top surface of the fixing block 32. The fixing block 32 can be installed and removed by threading the mounting column 33 with the mounting hole, so as to facilitate the installation of the fixing block 32 according to the number of the placement mechanism 5. The setting of the fixing block 32 can support the placement mechanism 5 from below when the placement mechanism 5 is stored.

[0041] A fixed magnetic sheet 56 is provided at the bottom end of the placement plate 51, and the fixed magnetic sheet 56 is provided corresponding to the fixed magnetic block 34; by providing the fixed magnetic sheet 56 corresponding to the fixed magnetic block 34, the stability of the placement mechanism 5 when being stored can be improved, and the placement mechanism 5 can be prevented from sliding and misaligning when the placement rack is moved;

[0042] In this embodiment, a cover plate 4 is provided at the top of the assembly mechanism 2 and the fixing mechanism 3, and a mounting opening 41 is provided on the bottom surface of the cover plate 4, which is engaged with the top of the assembly rod 21; a mounting groove 42 is provided on the side surface of the end of the cover plate 4, which is engaged with the top of the fixed vertical rod 31; through the mounting groove 42 and the mounting opening 41 provided at the bottom of the cover plate 4, it is convenient for the cover plate 4 to cover the placement mechanism 5 after the placement mechanism 5 and the assembly mechanism 2 are combined, so as to protect and shield the eight-link pipe 6 located higher up.

[0043] The working principle and use process of this utility model:

[0044] When using:

[0045] First, the multiple placement mechanisms 5 above the tray are pulled outward. At this time, the placement plate 51 in the placement mechanism 5 will slide on the outside of the movable plate through the movable groove 53 and the limit groove 531 provided inside. After the placement plate 51 is slid out, the placement plate 51 is rotated, and the rotating cylinder 55 in the middle of the movable plate 54 will rotate with the assembly rod 21 as a point. In this way, the placement mechanism 5 can be changed from the storage state to the taking state, thereby facilitating the experimenter to take and place the eight-tube 6;

[0046] During use:

[0047] After placing or taking the eight-tube 6, the placement plate 51 is pushed back to the top of the tray. At this time, the bottom of the placement plate 51 will contact the fixed block 32 in the fixing mechanism 3, and the fixed block 32 will support the placement plate 51. At the same time, the fixed magnetic block 34 in the fixed block 32 will be adsorbed with the fixed magnetic sheet 56 under the placement plate 51, so as to achieve the purpose of fixing and limiting the placement plate 51, so as to avoid the placement plate 51 from sliding and misaligning when the eight-tube 6 placement rack moves as a whole.
