[0032] Furthermore, the technical solutions between the various implementation modes of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] The first aspect of the present invention provides a sealing mechanism for a sample rack. Figure 1 and Figure 2 The closing mechanism includes a closing box 100 and a closing cover 200 .

[0034] The closed box 100 includes a plurality of walls and a support bar 110. The wall may be a thin-walled structure, which may be made of a hard material, such as a wooden board, a metal board, a plastic board, a glass board, etc. In this way, a plurality of closed boxes 100 may be stacked and placed to save storage space. In some embodiments, the wall may be made of a transparent material, such as a glass board, an acrylic board, etc. In this way, the morphology of the sample may be directly observed from outside the closed box 100, or the serial number on the sample rack 300 may be checked to quickly find the sample.

[0035] A plurality of walls surround and form a receiving cavity with an opening at one end, which can be understood as a structure surrounded by a plurality of walls having an opening on one side, such as a wall corresponding to the side being missing. The structure surrounded by a plurality of walls can be a structure of regular shape. Since the structure of the sample rack 300 is a rectangular parallelepiped, the structure surrounded by a plurality of walls can also be a notched rectangular parallelepiped, that is, a wall corresponding to a surface of the rectangular parallelepiped opposite to the length direction of the closed box 100 is missing, and the rectangular parallelepiped contains the receiving cavity. The following description is based on the example that the structure surrounded by a plurality of walls is a notched rectangular parallelepiped.

[0036] The number of the plurality of walls is 5, specifically including a first wall 120, a second wall 130, a third wall 140 and two side walls. The first wall 120 and the second wall 130 are arranged relative to each other in the height direction of the closed box 100, and the first wall 120 (for the convenience of description, it can also be called the top wall of the closed box 100) is located higher than the second wall 130 (for the convenience of description, it can also be called the top wall of the closed box 100). The third wall 140 is arranged relative to the opening (for the convenience of description, it can also be called the supporting wall of the closed box 100). The two side walls are connected between the first wall 120 and the second wall 130.

[0037] The support bars 110 are distributed on two opposite walls among the multiple walls, that is, located on two side walls. The support bars 110 are used to support the sample rack 300. The extension direction of the support bars 110 is toward the opening, so that the accommodating area 150 and the operating area 160 are both toward the opening.

[0038] See also Figure 3The support bar 110 may be arranged along the length direction of the closed box 100, or its extension direction may have a certain inclination angle relative to the length direction of the closed box 100. For example, in some embodiments, the height of the support bar 110 gradually decreases in the direction from the opening to the third wall 140. That is, the support bar 110 is inclined downward, for example, by 2 to 5 degrees, so that the height of the portion of the support bar 110 near the opening is slightly higher than the height of the portion of the support bar 110 near the third wall 140. Therefore, the sample rack 300 containing the sample is not easy to slide out of the opening by itself without operation.

[0039] See also Figure 4 and Figure 5 The support bar 110 divides the accommodating cavity into an accommodating area 150 located above the support bar 110 and an operating area 160 located below the support bar 110. The accommodating area 150 is larger than the operating area 160 and is adapted to the sample rack 300 containing the sample. The height and length of the accommodating area 150 can be larger than the corresponding height and length of the sample rack 300 containing the sample, and the width of the accommodating area 150 can be slightly larger than the corresponding width of the sample rack 300 containing the sample, or the two are equal. In this way, the convenience of the sample rack 300 containing the sample entering and exiting the accommodating area 150 and the stability of the sample rack 300 placed in the accommodating area 150 are achieved in a better balance.

[0040] The operation area 160 allows a gap between the bottom of the sample rack 300 and the bottom of the closed box 100 , such as a gap of 1 to 2 cm, so that fingers can enter the operation area 160 , so that the sample rack 300 can be held to enter and exit the closed box 100 .

[0041] The closing cover 200 is movably connected to a part of the wall bodies among the multiple wall bodies near the opening position, and the closing cover 200 has an open state for opening the accommodating cavity and a closed state for closing the accommodating cavity. The closing cover 200 is adapted to the shape of the opening, and can open or open the opening, thereby opening the open state of the accommodating cavity or being used for or closing the accommodating cavity.

[0042] In the above-mentioned closing mechanism for the sample rack, the closing box 100 has a receiving cavity with an opening at one end. The extension direction of the support bar 110 is toward the opening, so that the receiving area 150 is toward the opening. When the closing cover 200 is open, the sample rack 300 containing the sample can enter the receiving area 150 through the opening as a whole, and the sample in the sample rack 300 does not need to be transferred, thereby reducing the workload and saving the operation time. Then, the closing cover 200 is switched to a closed state, so that all the samples in the sample rack 300 are sealed and stored. Moreover, the operation area 160 makes the bottom of the sample rack 300 spaced from the bottom of the closing box 100, so that when the sample rack 300 enters the receiving area 150 or is taken out of the receiving area 150, the closing mechanism has a large operating space, and the operation is more convenient. In the above-mentioned closing mechanism for the sample rack, the operation is more convenient, the workload during sample processing is reduced, and the operation time is saved.

[0043] In some embodiments, see Figure 1 and Figure 2 The closing cover 200 is connected to the first wall 120 by rotation around the short side of the opening, and the rotation axis is parallel to the short side. That is, the closing cover 200 can be turned upside down to open or close the opening. Under the action of gravity, the closing cover 200 is normally in a state of closing the opening, thereby reducing the risk of samples being left in an open environment due to forgetting to close the closing cover 200, resulting in sample contamination or solvent volatilization.

[0044] In some embodiments, see Figure 1 and Figure 3 The closing mechanism further includes a fixing assembly 170 for fixing the closing cover 200 when it is opened.

[0045] For example, Figure 3 As shown, the fixing assembly 170 may include a push rod arranged on the top surface of the first wall body 120. The push rod is located near the first wall body 120 near the closing cover 200. The closing cover 200 is flipped up and rests on the push rod. The fixing assembly 170 of this type has a simple structure. It can be understood that in order to facilitate the stacking of the closing mechanism, a protrusion (not shown in the figure) that bulges toward the first wall body 120 is provided at the bottom of the second wall body 130 of the closing mechanism. The protruding portion forms a cavity on the bottom surface of the second wall body 130, and the cavity is matched to accommodate the push rod. And the height of the push rod is lower than the height of the operating area 160. In this way, two adjacent closing mechanisms can be stacked up and placed, and the push rod will not affect this, and the push rod can also realize axial positioning of the closing mechanism, so that the closing mechanism is not easy to tip over.

[0046] Exemplarily, the fixing assembly 170 may include a support rod disposed on the closing cover 200 and a support hole disposed on the side wall. One end of the support rod is rotatably connected to the closing cover 200. When the closing cover 200 is opened, one end of the support rod is extended into the support hole to be supported, so that the closing cover 200 remains in an open state, so that the sample rack 300 containing the sample can enter the containing area 150.

[0047] The support rod on the closing cover 200 and the support hole opened on the side wall are arranged. One end of the support rod is rotatably connected to the closing cover 200. When the closing cover 200 is opened, one end of the support rod is extended into the support hole to be supported, so that the closing cover 200 remains in an open state, so that the sample rack 300 containing the sample can enter the containing area 150.

[0048] In some embodiments, see Figure 1 and Figure 2 The sealing mechanism further includes a sealing strip 210 wrapped around the edge of the closing cover 200. The sealing strip 210 can be a flexible strip such as a rubber strip or a silicone strip, which can reduce the gap between the closing cover 200 and the opening and enhance the sealing performance of the closing cover 200.

[0049] In some embodiments, see Figure 3 The sealing mechanism further includes a buffer block 180. The buffer block 180 may be made of a flexible material such as sponge or rubber. The buffer block 180 is disposed on the surface of the third wall 140 close to the opening, and is used to abut against the sample rack 300. In this way, when the sample rack 300 is pushed into the receiving area 150, the buffer block 180 can abut against the sample rack 300 to play a buffering role, thereby preventing the sample rack 300 from applying excessive pressure to the third wall 140, causing the third wall 140 to be damaged or cracked.

[0050] In some embodiments, the support bar 110 includes a plurality of support segments, which are spaced apart along the length direction of the closed box 100. In this way, the contact area between the support bar 110 and the sample rack 300 can be reduced, thereby reducing the friction between the two, making the sample rack 300 enter and exit more smoothly.

[0051] In some embodiments, a ball bearing is embedded above the support bar 110. In this way, the sliding friction between the support bar 110 and the sample rack 300 is transformed into rolling friction, thereby reducing the friction between the two, making the sample rack 300 enter and exit more smoothly.

[0052] In some embodiments, the height of the operation area 160 in the height direction of the closed box 100 is 1.1 times the height of the sample rack 300 containing the sample. The top wall of the closed box 100 is 0.5 to 1 cm away from the top of the sample of the sample rack 300, and the top wall of the closed box 100 does not contact the sample to avoid contamination by the sample.

[0053] In some embodiments, the height of the operation area 160 in the height direction of the closed box 100 is 0.2 times the height of the sample rack 300 containing the sample. The height of the operation area 160 is suitable for easy operation.

[0054] The utility model also provides a sample rack 300 set, comprising a sample rack 300 and the above-mentioned sealing mechanism for the sample rack.

[0055] The above technical solutions of the present invention are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
