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

[0025] refer to Figure 1-6 A sealed bacterial culture device includes a housing 1 and a culture plate 2. A plurality of through holes can be provided on the culture plate 2. The through holes can increase the contact area between air and the culture plate, thereby increasing the contact between moisture in the air and the culture in the culture plate. This can improve the efficiency of moisture transfer, which is beneficial to the growth and reproduction of microorganisms during the culture process. A plurality of culture plates 2 can be provided.

[0026] A box door 103 is provided on one side of the shell 1, a support column 101 is connected inside the shell 1, and the two sides of the support column 101 are respectively connected to the top and the bottom of the shell 1, and a plurality of fixing holes 102 are arranged at intervals along the axial direction on both sides of the support column 101, a guide cylinder 201 is provided on the top of the culture tray 2, and a sliding groove 202 is provided inside the guide cylinder 201, the support column 101 is slidingly connected to the inner wall of the sliding groove 202, and fixed grooves 203 are provided on both sides of the sliding groove 202, and each fixed groove 203 is provided with a fixing column 204, and an accommodating space 205 is provided on one side of the fixing groove 203, and the accommodating space 205 is communicated with the fixing groove 203, and a fixing component for engaging the fixing column 204 with the fixing hole 102 or disengaging the fixing column 204 from the fixing hole 102 is provided in the accommodating space 205;

[0027] When the staff disengages the fixing column 204 from the fixing hole 102 and moves the guide cylinder 201, the support column 101 will be slidably connected to the inner wall of the sliding groove 202. By setting the guide cylinder 201 and the sliding groove 202, the culture plate 2 can be prevented from being offset during the movement, thereby improving the stability of adjusting the height of the culture plate 2.

[0028] The height of the culture tray 2 is adjusted by providing the support column 101, the guide cylinder 201, the fixing column 204 and the fixing assembly. When the staff needs to adjust the height of the culture tray 2, they only need to separate the fixing column 204 from the fixing hole 102 through the fixing assembly and move the guide cylinder 201 to complete the adjustment. This operation is simple and convenient, and there is no need to repeatedly rotate the threaded rod.

[0029] At the same time, since the fixing component is arranged in a relatively sealed manner inside the guide cylinder 201, the fixing component can be prevented from being corroded or rusted in a humid environment, thereby improving the stability of adjusting the height of the culture dish 2.

[0030] Furthermore, in order to ensure that the fixed column 204 can correspond to the fixed hole 102 each time the staff adjusts the height of the culture tray 2, a guide groove 206 is provided on one side of the support column 101, and a guide block 207 is provided on one side of the sliding groove 202, and the guide block 207 is slidably connected to the inner wall of the guide groove 206. The radial degree of freedom of the guide cylinder 201 is limited by the provided guide block 207 and the guide groove 206, so that the guide cylinder 201 can only move along the axial direction of the support column 101, so that each time the height of the culture tray 2 is adjusted, the fixed column 204 can correspond to the fixed hole 102, which is convenient for the staff to adjust the height of the culture tray 2.

[0031] Specifically, the fixing assembly includes an elastic member 3, a pressure plate 301, a pressure rod 302, and two connecting rods 303. The elastic member 3 is a cylindrical compression spring, which can store energy efficiently and release it when needed.

[0032] One end of the elastic member 3 is in contact with the side of the accommodating space 205 facing the door, and the other end of the elastic member 3 is fixedly connected to the pressure plate 301, and the pressure plate 301 is slidably connected to the upper and lower sides of the accommodating space 205. When one end of the elastic member 3 is in contact with the side of the accommodating space 205 facing the door, the pressure plate 301 can face the front of the person, which can facilitate the staff to compress the elastic member 3 and improve convenience. One end of the two connecting rods 303 is rotatably connected to the two sides of the pressure plate 301, and the other end of the two connecting rods 303 is rotatably connected to the two fixing columns 204 (it should be noted here that reference Figure 6 When the connection relationship between the two connecting rods 303 and the pressure plate 301 is projected on a horizontal plane, the angle between the pressure plate 301 and the connecting rod 303 is greater than 90 degrees and less than 180 degrees, which is convenient for the staff to press the pressure rod 302). The pressure rod 302 is arranged on the side of the pressure plate 301 facing the box door, and one end of the pressure rod 302 passes through the side of the guide cylinder 201 and extends to the outside of the guide cylinder 201.

[0033] When the staff needs to adjust the height of the culture tray 2, they only need to press the pressure rod 302, and the pressure rod 302 will drive the pressure plate 301 to move in the direction of the compression elastic member 3. In order to facilitate the staff to press the pressure rod 302, a circular arc structure is designed on the side of the pressure rod 302 away from the guide cylinder 201. The circular arc surface is smooth and has no sharp edges or protrusions to avoid stabbing the fingers of the staff, thereby improving the safety of operation. When the pressure plate 301 moves in the direction of the compression elastic member 3, the pressure plate 301 drives the fixing column 204 to disengage from the fixing hole 102 through the connecting rods 303 on both sides. When the fixing column 204 disengages from the fixing hole 10 2, the staff can release the finger pressing the pressure rod 302 and move the guide cylinder 201. Under the action of the elastic member 3, the fixing column 204 is always in contact with the outer surface of the support column 101. In order to increase the service life of the fixing column 204, the side of the fixing column 204 close to the fixing hole 102 is in an arc shape, which reduces the contact area with the outer surface of the support column 101, thereby reducing wear and tear, and further increasing the service life of the support column 101. When moving to the next fixing hole 102, the fixing column 204 will automatically pop up under the action of the elastic member 3, and form a snap connection with the fixing hole 102, thereby fixing the culture tray 2.

[0034] Since the shell 1 has a certain depth inside, it is not very convenient to place the culture dish. In this embodiment, guide rails 4 are provided at the top and bottom of the inner side of the shell 1, and each guide rail 4 is slidably connected with a slider 401. The two sides of the support column 101 are fixedly connected to the top and bottom sliders 401 respectively. When the staff needs to place the culture dish, they only need to pull out the culture tray 2 with one hand, and the culture tray 2 will drive the support column 101 to move away from the inside of the shell 1, thereby driving the slider 401 to move, which makes it easier for the staff to place the culture dish. In order to facilitate the staff to move the slider 401, a ball 402 is provided on the top of each guide rail 4, and the ball 402 is slidably connected to the slider 401. The ball 402 can reduce the friction between the guide rail 4 and the slider 401, thereby facilitating the staff to move.

[0035] In order to prevent the staff from pulling out the entire culture tray 2, a baffle 403 is provided on the inner bottom side of the shell 1 close to the box door, and a limit block 404 is provided on the side of the slider 401 away from the box door. The limit block 404 abuts against the baffle 403. When the staff pulls the culture tray 2 outward, the limit block 404 will abut against the baffle 403, thereby limiting the slider 401 and preventing the entire culture tray 2 from being pulled out.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
