Description

Technical Field

[0001] The utility model belongs to the technical field of PCR experimental tools, and particularly relates to a PCR multi-tube cap opener. Background Art

[0002] The consumables commonly used in PCR experiments are PCR octa-tubes or other types of PCR tubes, which are designed to arrange multiple reaction tubes in a row for batch processing. During the PCR experiment, the operator often needs to open and close the caps of the PCR tubes. Especially when adding reagents, samples or performing subsequent processing, opening the cap is an essential step. However, with the increase in experimental requirements and the expansion of the operation batch, there are many problems in the actual application of the traditional cap-opening method:

[0003] The existing technology usually only supports single-row cap opening. If the operator needs to open the caps of multiple rows of PCR octa-tubes simultaneously, the equipment or method of the existing technology cannot ensure the stability of the tubes. In addition, when opening the caps, multiple rows of tubes cannot be processed at one time, and it is necessary to open the caps row by row, resulting in low operation efficiency and poor stability.

[0004] Therefore, the utility model provides a PCR multi-tube cap opener. Summary of the Utility Model

[0005] The utility model designs a PCR multi-tube cap opener to solve the problems existing in the above background art.

[0006] In order to achieve the above technical effects, the utility model is realized by the following technical solutions: a PCR multi-tube cap opener, comprising an inserting plate assembly and a supporting assembly.

[0007] Further, the inserting plate assembly includes a lower inserting plate and an upper inserting plate rotatably connected to the lower inserting plate; the supporting assembly includes a grip rod fixedly connected to the rear end of the lower inserting plate and a rotating rod fixedly connected to the upper inserting plate.

[0008] Further, a plurality of lower inserting rods are provided on the lower inserting plate, an anti-slip pad is provided at the bottom end of the lower inserting rod, a plurality of upper inserting rods are provided on the upper inserting plate, and the front ends of the lower inserting rod and the upper inserting rod are rotatably hinged.

[0009] Further, a T-shaped grip is provided at the rear end of the grip rod.

[0010] Further, a T-shaped rotating handle is provided at the rear end of the rotating rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model allows operators to quickly open the tube caps of PCR octuplets through simple insertion and rotation actions. It can not only open the caps of single-row PCR octuplets, but also, by adjusting the insertion position of the lower insertion rod, achieve the cap-opening operation for multi-row PCR octuplets. This reduces the time required for manually opening each cap one by one and greatly improves the working efficiency of the laboratory;

[0013] 2. After the lower insertion rod is inserted into the gap between the PCR tubes, by holding the T-shaped handle and further pressing the lower insertion plate to ensure the stability of the octuplets, it can effectively prevent the PCR octuplets from slipping out of the tube rack box due to external force during cap opening, ensuring the safety of the experiment and the stability of the operation.

[0022] Embodiment 1

[0023] Refer to Figures 1 to 4 As shown, a PCR tube cap opener includes an insertion plate assembly 1 and a support assembly 2. Both the insertion plate assembly 1 and the support assembly 2 are made of rigid plastic. The insertion plate assembly 1 includes a lower insertion plate 11 and an upper insertion plate 12 rotatably connected to the lower insertion plate 11. The support assembly 2 includes a grip rod 21 fixedly connected to the rear end of the lower insertion plate 11 and a rotating rod 22 fixedly connected to the upper insertion plate 12.

[0024] A plurality of lower insertion rods 111 are provided on the lower insertion plate 11. An anti-slip pad is provided at the bottom end of the lower insertion rod 111 to ensure the stability of the connection between the bottom end of the lower insertion rod 111 and the PCR tube. A plurality of upper insertion rods 121 are provided on the upper insertion plate 12. The front ends of the lower insertion rods 111 and the upper insertion rods 121 are rotatably connected.

[0025] A T-shaped grip 211 is provided at the rear end of the grip rod 21.

[0026] A T-shaped rotating handle 221 is provided at the rear end of the rotating rod 22.

[0027] Embodiment 2

[0028] The operating principle of the present utility model:

[0029] Each single tube in the PCR octuplex tube is connected adjacent to each other, and there are gaps between these adjacent single tubes. Similarly, there is also a connection between adjacent tube caps. The purpose of this structural design is to place multiple rows of PCR octuplex tubes together in a suitable tube rack box to maintain stability during operation.

[0030] When an operator performs an opening operation on the PCR octuplex tube, when only opening one row of PCR octuplex tubes, the operator needs to insert the front ends of multiple lower insertion rods 111 into the connection gaps between the PCR octuplex tubes respectively. This step is to firmly fix the PCR octuplex tube by the lower insertion plate to ensure that the tubes do not detach from the tube rack box during the opening operation. When it is necessary to open multiple rows of PCR octuplex tubes, the operator needs to insert multiple lower insertion rods 111 through the connection gaps between multiple columns of PCR octuplex tubes. This operation is equivalent to inserting the lower insertion rods into each column of PCR octuplex tubes to ensure that all octuplex tubes are stably fixed.

[0031] The operator holds the T-shaped grip 211 of the grip rod 21 with one hand, which is the fixed part of the opener. By pressing the lower insertion plate 11, the lower insertion rods 111 on the lower insertion plate 11 tightly press against the connection part of the PCR octuplex tube. The purpose of this step is to ensure the stability of the PCR octuplex tube during the entire operation and prevent it from detaching from the tube rack box due to the applied external force. Hold the T-shaped rotating handle 221 with the other hand. The operator drives the multiple upper insertion rods 121 on the upper insertion plate 12 by rotating the T-shaped rotating handle 221, so that the upper insertion rods 12 are disengaged from the connection gaps of the PCR octuplex tube.

[0032] The disengaging action of the upper insertion rod 121 will push open the tube lid of the PCR octuplet tube, and the rotation of the upper insertion plate realizes the opening of the tube lid.

[0033] Through these two steps, that is, the lower insertion plate fixes the octuplet tube and the upper insertion plate rotates to push open the tube lid, the operator completes the operation of opening the lid of the PCR octuplet tube.

[0034] The utility model realizes the rapid opening of the lid of single-row or multi-row PCR octuplet tubes through simple insertion and rotation operations, significantly improves the experimental efficiency, and prevents the tubes from sliding or disengaging during the lid-opening process, ensuring the stability and safety of the operation.
