Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figures 1 - 7 , a microbial culture kit with good sealing performance of the present utility model includes a kit 1. A culture test tube 4 is placed on the inner bottom surface of the kit 1. A sealing cover 2 is placed on the top of the kit 1. Mounting blocks 101 are respectively fixed on both sides of the kit 1. A fixing component 3 is arranged on the mounting blocks 101. Two placing plates 102 are respectively fixed on both sides inside the kit 1. A fixed air cushion 1021 is arranged on the inner wall of the circular groove of the placing plate 102. A culture test tube 4 passing through the circular groove of the placing plate 102 is placed inside the fixed air cushion 1021. The fixing component 3 includes a screw 301 rotatably connected to the top of the mounting block 101. A moving block 302 is threadedly connected to the screw 301. Two pressing plates 3021 are fixed on one side of the moving block 302. Two piston rods 303 are fixed on the bottom of the moving block 302. The piston rods 303 are slidably connected inside the piston cylinder 304. The piston cylinder 304 is fixed on one side of the kit 1. An air passage connecting the piston cylinder 304 and the fixed air cushion 1021 is provided on the kit 1.

[0025] Specifically, when this case is actually used, the culture test tube 4 is placed inside the fixed air cushion 1021 fixed in the placement plate 102. After the sealing cover 2 is placed on the top of the reagent kit 1, the screw 301 on the mounting block 101 is rotated, and the moving block 302 indirectly connected by threads moves downward, driving the piston rod 303 at the bottom to move downward inside the piston cylinder 304. The piston rod 303 fits tightly with the piston cylinder 304. Therefore, the gas in the piston cylinder 304 is squeezed into the fixed air cushion 1021 through the air duct, and the fixed air cushion 1021 expands to fix the culture test tube 4. At the same time, the pressing plate 3021 on one side of the moving block 302 presses and fixes the sealing cover 2 during the downward movement. This assembly simultaneously completes the fixation of the culture test tube 4 and the sealing of the reagent kit 1 during the downward movement process. The operation process is simple, the fixation effect is good, and the culture test tube 4 will not be damaged.

[0026] Combined with Figures 3 - 6 , a rubber head 3031 is fixed at the bottom of the piston rod 303, and the rubber head 3031 fits tightly with the inner wall of the piston cylinder 304. Fixing the rubber head 3031 that fits tightly with the inner wall of the piston cylinder 304 at the bottom of the piston rod 303 can form a good sealing effect to prevent gas leakage. The surface of the rubber block is smooth, the friction coefficient is small, and the wear with the components is relatively small, which helps to extend the service life of the components.

[0027] A positioning block 3022 is fixed at the bottom of the pressing plate 3021, and four positioning holes 202 are opened at the top of the sealing cover 2. The positioning block 3022 corresponds to the positions of the positioning holes 202. Before the pressing plate 3021 completes the pressing during the downward movement, the positioning block 3022 fixed at its bottom is inserted into the corresponding positioning holes 202 at the top of the sealing cover 2 to complete the initial positioning and fixation, which can ensure the precise fixation of the firmware, prevent deviation, strengthen the fixation between the reagent kit 1 and the sealing cover 2, and improve the stability of the device.

[0028] A convex rubber pad 201 is fixed at the bottom of the sealing cover 2, and the convex rubber pad 201 fits with both the top and the inner wall of the reagent kit 1 when closed. Fixing the convex rubber pad 201 that fits with both the top and the inner wall of the reagent kit 1 at the bottom of the sealing cover 2 effectively strengthens the sealing of the reagent kit 1 after the sealing cover 2 is pressed, ensuring the internal environment.

[0029] Combined with Figures 1 - 3 and Figure 7 , a placement pad 103 is installed at the bottom position of the culture test tube 4 inside the reagent kit 1. A notch is opened at the top of the placement pad 103 corresponding to the culture test tube 4. The placement pad 103 is made of sponge material. The placement pad 103 made of sponge is placed inside the reagent kit 1. A notch corresponding to the position of the culture test tube 4 is opened at the top of the placement pad 103 for placing the culture test tube 4 to prevent the position of the culture test tube 4 from shifting.

[0030] There are four anti-slip pads 104 distributed in a matrix at the bottom of the kit 1. The bottom of the anti-slip pads 104 is provided with regular anti-slip patterns. The four anti-slip pads 104 with regular anti-slip patterns distributed in a matrix at the bottom of the kit 1 can effectively ensure stable placement and prevent the shaking of the internal culture test tubes 4 caused by the unstable placement of the kit 1.

[0031] Openings are provided at the corresponding positions of the two sides of the kit 1 and the culture test tubes 4. Glass 105 is embedded in the openings. By providing openings at the positions where the culture test tubes 4 are placed on the two sides of the kit 1 and embedding and installing the glass 105 inside the openings, it can effectively isolate air and dust and also facilitate observing the culture conditions in the culture test tubes 4.
