[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 8 As shown, the utility model provides a highly sealed sample storage device for water conservancy testing, comprising a storage box 1 and a box cover 2. The box cover 2 is arranged on the storage box 1 from the top downward, and the storage box 1 and the box cover 2 are both provided with connecting buckles on the left and right sides. A plurality of storage slots 16 are provided in the storage box 1. The storage slots 16 are used to place water conservancy testing samples. A silicone airbag 10 is provided in the storage slot 16. The function of the silicone airbag 10 is to wrap and fix the sample tube to prevent the sample tube from shaking in the storage slot 16. The bottom surface of the box cover 2 is fixedly connected with a plurality of extrusion cylinders 7 corresponding to the silicone airbags 10. Through the setting of the extrusion cylinder 7, when the sample tube is placed in the storage After being placed in the groove 16, the box cover 2 can be moved downward to make the extrusion cylinder 7 squeeze the top of the silicone airbag 10, so that the silicone airbag 10 expands toward the middle, and then squeezes and wraps the sample tube in the silicone airbag 10. The inner wall of the extrusion cylinder 7 is elastically and slidably provided with an extrusion plate 8. With the setting of the extrusion plate 8, the top of the sample tube can be squeezed and fixed to prevent the sample tube from shaking up and down in the storage groove 16. A second sealing groove 14 is provided on the storage box 1, and a first sealing frame 3 is fixed to the bottom surface of the box cover 2, and the first sealing frame 3 is inserted into the second sealing groove 14. By inserting the first sealing frame 3 into the second sealing groove 14, the sealing between the storage box 1 and the box cover 2 can be ensured.

[0026] like Figure 6 and Figure 8 As shown, the lower half of the surface of the silicone airbag 10 is fixed to the inner wall of the storage groove 16, and the upper half of the surface of the silicone airbag 10 slides elastically on the inner wall of the storage groove 16, so that the lower half of the silicone airbag 10 can be fixed in the storage groove 16 to prevent the silicone airbag 10 from moving around at will. The upper half of the silicone airbag 10 can slide up and down in the storage groove 16, so that after the top of the silicone airbag 10 is squeezed downward, the inner wall of the silicone airbag 10 can move closer to the middle, thereby wrapping and fixing the sample tube in the middle of the silicone airbag 10.

[0027] like Figures 5 to 8As shown, the inner wall of the storage groove 16 is provided with a plurality of slots 18, and the inner wall of each slot 18 is fixedly connected to a guide rod 17, and each guide rod 17 is sleeved with a movable plate 11 and a first compression spring 13, and the two ends of the first compression spring 13 are respectively fixedly connected to the inner bottom wall of the slot 18 and the bottom surface of the movable plate 11, and one end of each movable plate 11 is fixedly connected to the top of the surface of the silicone airbag 10. Through the setting of the above structure, when the box cover 2 drives the extrusion cylinder 7 away from the silicone airbag 10, the elastic force of the first compression spring 13 can be utilized to make the movable plate 11 drive the silicone airbag 10 to be pulled upward, thereby ensuring that the sample tube in the silicone airbag 10 is normally taken out, and at the same time, it also ensures that the top of the silicone airbag 10 can slide up and down stably, ensuring that the middle part of the silicone airbag 10 wraps the sample tube.

[0028] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As shown, the top end of the silicone airbag 10 is fixedly connected with a second sealing strip 12, and the bottom end of the extrusion cylinder 7 is provided with a first sealing groove 9 adapted to the second sealing strip 12. Through the setting of the second sealing strip 12 and the first sealing groove 9, the contact sealing between the extrusion cylinder 7 and the silicone airbag 10 can be guaranteed, thereby ensuring the sealing of the sample tube between the silicone airbag 10 and the extrusion cylinder 7.

[0029] like Figure 6 and Figure 8 As shown, a second compression spring 15 is fixedly connected to the extrusion plate 8, and the top end of the second compression spring 15 is fixedly connected to the inner top wall of the extrusion cylinder 7, so that the extrusion plate 8 can have a buffering effect when squeezing the top end of the sample tube, thereby ensuring the protection effect of the top end of the sample tube, and the material of the extrusion plate 8 is silicone.

[0030] like Figure 2 As shown, a card slot 6 is provided on the back of the storage box 1, and an elastic card plate 5 is fixedly connected to the rear end of the storage box 1, and the bottom end of the elastic card plate 5 is clamped in the card slot 6. Through the arrangement of the elastic card plate 5 and the card slot 6, when the storage box 1 is covered, the elastic card plate 5 can be gradually clamped in the card slot 6, thereby preventing the box cover 2 from being difficult to press downward and moving, and preventing the box cover 2 from being pushed upward.

[0031] like Figure 1 and Figure 2 As shown, protective sleeves 4 are fixedly connected to the four corners of the storage box 1, and a silicone pad is provided on the inner bottom wall of the storage groove 16. The setting of the protective sleeves 4 can protect the side of the storage box 1. The setting of the silicone pad can protect the bottom end of the sample tube in the storage groove 16 to prevent the sample tube from being damaged when placed.

[0032] The working principle and usage process of the present invention are as follows: after the sampling of the sample tubes is completed, they can be placed one by one in the storage groove 16, then the box cover 2 is placed on the storage box 1, and the first sealing frame 3 is inserted into the second sealing groove 14 to ensure the sealing effect between the storage box 1 and the box cover 2. At the same time, the bottom end of the extrusion cylinder 7 is also above the corresponding silicone airbag 10, and squeezes the silicone airbag 10 downward, so that the top end of the silicone airbag 10 can make the inner wall of the silicone airbag 10 move closer to the middle after being squeezed downward, wrapping and fixing the sample tube in the middle of the silicone airbag 10, and at this time the extrusion plate 8 will also squeeze and fix the top end of the sample tube to prevent it from shaking, and the contact between the silicone airbag 10 and the extrusion cylinder 7 ensures the sealing of the sample tube in the storage groove 16, thereby preventing the liquid in the sample tube from leaking. When the box cover 2 is away from the storage box 1, the top end of the silicone airbag 10 will be pushed upward by the elastic force of the first compression spring 13, so that it is convenient for personnel to take out the sample tube for subsequent storage of the sample tube.
