[0001] This utility model relates to the field of fecal sulfur bacteria preparation technology, specifically a fecal sulfur bacteria preparation culture medium. Background Technology

[0002] In the preparation and cultivation of fecal sulfur bacteria, petri dishes are needed to hold the culture medium for bacterial growth. However, different experimental requirements or different cultivation procedures may require the use of petri dishes of different sizes.

[0003] Most existing petri dish placement devices have fixed structures and cannot flexibly adjust the placement space according to the size of the petri dishes, resulting in inconvenience and reduced experimental efficiency. In addition, when handling petri dishes, because the placement position of the petri dishes is fixed and may be located deep inside the device, it is inconvenient for operators to handle them, and the petri dishes are prone to collision or contamination, which affects the cultivation effect of fecal sulfur bacteria. Therefore, a fecal sulfur bacteria preparation culture medium is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a culture medium for preparing fecal sulfur bacteria, which has advantages such as strong adaptability and ease of handling, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A culture medium for preparing fecal sulfur bacteria includes a box body, a door hinged to the outside of the box body, and two shelves disposed inside the box body. The outside of the box body is provided with a spacing adjustment mechanism for adjusting the distance between the two shelves. The upper surface of each shelf is provided with a number of storage trays.

[0007] The spacing adjustment mechanism includes a fixed frame fixedly connected to the outside of the housing. A dual-axis cylinder is fixedly installed inside the fixed frame. Connecting ears are fixedly connected to both output ends of the dual-axis cylinder, and the connecting ears are fixedly connected to the outside of the shelf.

[0008] Furthermore, the shelf is slidably connected to the inside of the box, and the outer diameter of the shelf is adapted to the inner diameter of the box.

[0009] Furthermore, the interior of the housing is provided with a movable opening adapted to the connecting lug, and a sealing gasket adapted to the connecting lug is fixedly installed inside the movable opening.

[0010] Furthermore, the interior of the housing is fixedly connected to two guide shafts, and the shelf is slidably connected to the outside of the two guide shafts.

[0011] Furthermore, the upper surface of the shelf is provided with a switching mechanism for rotating and switching the plurality of storage trays. The switching mechanism includes a drive motor fixedly installed on the top of the shelf and a rotating shaft rotatably connected to the top of the shelf. A worm gear is fixedly connected to the output shaft of the drive motor, and a worm wheel meshing with the worm gear is fixedly installed on the outside of the rotating shaft.

[0012] Furthermore, a support plate is fixedly connected to the top of the rotating shaft, and several storage trays are arranged in a ring shape on the top of the support plate.

[0013] Furthermore, the bottom of the box is rotatably connected to four movable wheels equipped with foot brakes, which are distributed at equal intervals on the bottom of the box.

[0014] Furthermore, an observation port is provided inside the door, and tempered glass is embedded inside the observation port.

[0015] Compared with the prior art, this utility model provides a culture medium for preparing fecal sulfur bacteria, which has the following characteristics:

[0016] Beneficial effects:

[0017] 1. The culture medium for preparing fecal sulfur bacteria can flexibly adjust the distance between two plates by extending and retracting the output end of the biaxial cylinder in the spacing adjustment mechanism, so as to meet the storage requirements of petri dishes of different heights.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 In this embodiment, a culture medium for preparing fecal sulfur bacteria includes a box body 1, a box door 2 hinged to the outside of the box body 1, and two shelves 3 disposed inside the box body 1. The outside of the box body 1 is provided with a spacing adjustment mechanism 4 for adjusting the distance between the two shelves 3. Several storage trays 5 are provided on the upper surface of the shelves 3.

[0025] The spacing adjustment mechanism 4 includes a fixed frame 41 fixedly connected to the outside of the housing 1. A dual-axis cylinder 42 is fixedly installed inside the fixed frame 41. Connecting ears 43 are fixedly connected to the two output ends of the dual-axis cylinder 42. The connecting ears 43 are fixedly connected to the outside of the shelf 3.

[0026] Specifically, shelf 3 is slidably connected to the interior of housing 1, and the outer diameter of shelf 3 matches the inner diameter of housing 1. The interior of housing 1 has a movable opening that matches the connecting lug 43, and a sealing gasket that matches the connecting lug 43 is fixedly installed inside the movable opening. By installing a sealing gasket inside the movable opening, the sealing performance of the dual-shaft cylinder 42 during movement is ensured, preventing external contamination from entering the interior of housing 1 and reducing the risk of contamination.

[0027] It should be noted that two guide shafts 44 are fixedly connected inside the housing 1, and the shelf 3 is slidably connected to the outside of the two guide shafts 44. By setting the shelf 3 to be slidably connected to the outside of the guide shafts 44, a guiding function is provided for the movement of the shelf 3, ensuring that the shelf 3 remains stable during movement, improving the accuracy of spacing adjustment and the reliability of device operation.

[0028] Please see Figures 1 to 3In this embodiment, the upper surface of the shelf 3 is provided with a switching mechanism 6 for rotating and switching several storage trays 5. The switching mechanism 6 includes a drive motor 61 fixedly installed on the top of the shelf 3 and a rotating shaft 63 rotatably connected to the top of the shelf 3. A worm gear 62 is fixedly connected to the output shaft of the drive motor 61, and a worm wheel 64 meshing with the worm gear 62 is fixedly installed on the outside of the rotating shaft 63. Each shelf 3 is provided with a switching mechanism 6 for rotating and switching the storage trays 5, making it convenient to retrieve petri dishes in different positions. When it is necessary to rotate the storage trays 5, the drive motor 61 is started, and the drive motor 61 drives the worm gear 62 to rotate. The worm gear 62 drives the rotating shaft 63 to rotate through meshing with the worm wheel 64. The support plate 65 on the top of the rotating shaft 63 rotates accordingly, thereby driving the several storage trays 5 distributed in a ring shape on the support plate 65 to rotate, realizing the switching of different storage trays 5.

[0029] A support plate 65 is fixedly connected to the top of the rotating shaft 63, and several storage trays 5 are arranged in a ring shape on the top of the support plate 65. The rotation of the storage trays 5 is achieved by utilizing the transmission principle of the worm gear 62 and the worm wheel 64. The operator only needs to start the drive motor 61 to easily rotate the required petri dishes to an easily accessible position, avoiding collisions or contamination that may be caused by reaching deep into the petri dishes, thus improving operational efficiency and experimental accuracy.

[0030] Specifically, the bottom of the chamber 1 is rotatably connected to four casters 7 equipped with foot brakes, arranged at equal intervals. An observation port is located inside the door 2, with tempered glass embedded within it. When the culture medium for preparing fecal sulfur bacteria needs to be moved, the chamber 1 is pushed, causing the casters 7 to roll on the ground, thus moving the device. Once the desired position is reached, the foot brake is depressed to lock the casters 7 and prevent further movement. Operators can observe the growth of fecal sulfur bacteria in the culture dishes inside the chamber 1 through the tempered glass without opening the door 2, thus avoiding interference with the internal environment.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the culture dishes containing fecal sulfur bacteria are placed in several storage trays 5 on the upper surface of the shelf 3. The storage trays 5 provide a stable position for the culture dishes, ensuring that they do not shake during the culture process. When the device needs to be moved, the operator only needs to apply external force to push the box 1, and the moving wheels 7 will roll on the ground, thereby moving the device and facilitating its transport to the desired location. When it is necessary to adjust the distance between two shelves 3, the operator activates the extension and retraction of the dual-axis cylinder 42 through the controller. The two output ends of the dual-axis cylinder 42 will extend or retract simultaneously, driving the connecting ears 43 to move. Under the guidance of the guide shaft 44, the shelf 3 will move with the connecting ears. The movement of 43 allows for smooth sliding, thereby adjusting the distance between the two shelves 3. When it is necessary to retrieve a culture dish from a different location, the output shaft of the drive motor 61 drives the worm gear 62 to rotate. Since the worm gear 62 meshes with the worm wheel 64, it in turn drives several storage trays 5 arranged in a ring shape on the support plate 65 to rotate, realizing the switching of different storage trays 5, which makes it convenient for operators to retrieve the required culture dishes. During the culture of fecal sulfur bacteria, the operator can observe the growth of fecal sulfur bacteria in the culture dishes inside the box 1 through the tempered glass on the box door 2. This not only facilitates observation but also avoids interfering with the culture environment inside the box by opening the box door 2, which is conducive to the normal growth of fecal sulfur bacteria.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
