[0025] See also Figure 1-3 , a storage device for pre-treated samples, comprising a sample storage box 1, a box cover 7 connected to the top of the sample storage box 1, and a handle 8 installed on the top of the box cover 7, four fixing blocks 4 are relatively installed on the outer wall of the sample storage box 1, and the four fixing blocks 4 are relatively installed in pairs, wherein the fixing blocks 4 shrink from top to bottom toward the inner wall of the sample storage box 1, and are in an inverted cone shape, a fixing cylinder 3 is connected to the bottom of the box cover 7, the interior of the fixing cylinder 3 is hollow, and the size of the inner diameter of the fixing cylinder 3 is larger than the size of the outer diameter of the sample storage box 1, four installation grooves 10 are opened on the inner wall opposite to the fixing cylinder 3, wherein the four installation grooves 10 and the fixed blocks 4 are distributed in the same manner on the side wall of the sample storage box 1, elastic positioning components are installed inside the four installation grooves 10, and positioning blocks 14 are installed on the side walls of the elastic positioning components, wherein the four positioning blocks 14 are respectively connected to the four fixing blocks 4 The fixing block 4 is clamped with the positioning block 14, wherein the positioning block narrows from top to bottom toward the inner wall of the fixing tube 3 and is conical. The side wall where the fixing block 4 is clamped with the positioning block 14 is inwardly staggered. The elastic positioning assembly includes an elastic spring 9 installed laterally inside the mounting groove 10, and a connecting block 15 installed on the end of the elastic spring 9 away from the mounting groove 10. The positioning block 14 is fixedly installed on the side wall of the connecting block 15 away from the elastic spring 9, so that the elastic force of the elastic spring 9 can maintain the tendency to move toward the fixing block 4, and the fixing block 4 can be clamped with the positioning block 14 in the form of an inwardly staggered buckle. Because the fixing block 4 is fixed on the outer wall of the sample storage box 1, the positioning block 14 will maintain a tendency to move downward, so that the box cover 7 can maintain a tendency to move downward, thereby making the sample storage box 1 achieve a sealing effect.

[0026] In this embodiment, a first hemisphere 5 is installed on the top of the fixing block 4, and a second hemisphere 13 is installed on the bottom of the positioning block 14. Due to the spherical characteristics of the first hemisphere 5 and the second hemisphere 13, when the box cover 7 is pressed from top to bottom for installation, the positioning block 14 can be easily retracted into the inside of the installation groove 10, thereby facilitating the locking of the positioning block 14 with the fixing block 4.

[0027] In this embodiment, limiting sliders 12 are installed on the two side walls separated from each other of the connecting block 15, and limiting slots 11 are transversely opened on the two side walls opposite to the installation groove 10, wherein the two limiting sliders 12 are slidably connected with the two limiting slots 11 respectively, and the two limiting slots 11 are transversely opened, so that the two limiting sliders 12 can only move transversely, and then the positioning block 14 can only move transversely through the elastic force of the elastic spring 9 and the reverse force of the fixed block 4, and will not deviate downward or upward, so that the positioning block 14 can achieve the effect of stable snap-fitting with the fixed block 4.

[0028] In this embodiment, a partition 2 is installed inside the sample storage box 1. The partition 2 is used to divide the interior of the sample storage box 1 into several independent spaces, so as to facilitate the classified storage of samples.

[0029] In this embodiment, a sealing gasket 6 is installed at the bottom of the box cover 7, and the sealing gasket 6 can effectively increase the sealing performance of the storage device.

[0030] Working principle: put the sample into the sample storage box 1, then close the box cover 7, press the box cover 7, so that the second hemisphere 13 slides through the first hemisphere 5, and then the positioning block 14 moves to the inside of the installation groove 10, so that the elastic spring 9 contracts. When the positioning block 14 is completely moved to the side wall of the fixed block 4, release your hand, and the positioning block 14 will move toward the fixed block 4 through the elastic force of the elastic spring 9, thereby forming a stable internal staggered shape, so that the positioning block 14 can maintain the trend of moving downward, and further enable the box cover 7 to stably cover the sample storage box 1, thereby achieving the effect of increasing the airtightness of the storage device. When the box cover 7 needs to be opened, just rotate the box cover 7 to release the snap-fit ​​relationship between the positioning block 14 and the fixed block 4, and then the box cover 7 can be opened.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
