Description

Technical Field

[0001] This utility model relates to the field of biological experimental technology, specifically a biological experimental culture dish rack. Background Technology

[0002] A petri dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is generally made of glass or plastic. Petri dishes are basically divided into two categories: plastic and glass. Glass petri dishes can be used for the culture of plant materials, microorganisms, and adherent cultures of animal cells. Plastic petri dishes are likely made of polyethylene and are available in disposable and reusable versions. They are suitable for laboratory inoculation, streaking, and bacterial isolation procedures, and can be used for the culture of plant materials.

[0003] Existing petri dishes require a rack for storage and positioning during use. Most existing racks use metal or plastic rods to position the petri dishes. Since petri dishes vary in size, some racks cannot be adjusted, meaning that a rack of a certain size can only hold petri dishes of that size.

[0004] Meanwhile, when using existing placement racks, most petri dishes are simply stacked on them. However, when all the petri dishes need to be removed, staff have to take them out one by one, which is not only cumbersome, but also prone to causing the petri dishes to tilt during the removal process, affecting the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide a biological experimental culture dish rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biological experimental culture dish rack, comprising a mounting plate and mounting shells fixed to both sides, and further comprising:

[0007] A threaded rod is installed inside the housing cavity. A sleeve is threadedly connected to the surface of the threaded rod. A fixed frame is rotatably connected to the top of the sleeve. Positioning rods are fixedly connected to both sides of the top of the fixed frame.

[0008] A connecting frame is fixed to the top of the fixing frame. A locking rod is slidably connected to the inner cavity of the connecting frame. An adjustment mechanism is installed on the top of the locking rod. A locking hole is opened on the top of the sleeve.

[0009] Preferably, the adjustment mechanism includes a movable frame fixed to the top of the locking rod and a tension spring fixed to the other end of its bottom and fixedly connected to the connecting frame. A connecting rod is fixedly connected to one side of the bottom of the movable frame.

[0010] Preferably, a limiting groove is formed on one side of the top of the connecting frame, and the inner wall of the limiting groove is slidably connected to the surface of the connecting rod.

[0011] Preferably, the other end of the threaded rod is fixedly connected to a bearing seat, and the other side of the bearing seat is fixedly connected to the inner wall of the mounting shell.

[0012] Preferably, positioning grooves are provided on both sides of the mounting plate, and the inner wall of the positioning groove is designed with an arc shape.

[0013] Preferably, the surface of the sleeve is slidably connected to the inner wall of the mounting shell, and the top of the sleeve is at the same horizontal line as the top of the mounting shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes the cooperation between a threaded rod and a sleeve to adjust the position of the positioning rod, allowing the placement rack to accommodate culture dishes of different sizes. This not only facilitates adjustment but also enhances the applicability of the placement rack. Furthermore, the locking rod and locking hole work together to release the limiting mechanism, allowing the fixing frame to be rotated directly to push the positioning rod out of the culture dish. This not only makes it easier to remove the culture dish but also prevents it from tilting, further improving the convenience of the device. It solves the problems of existing placement racks, which are inconvenient for placing culture dishes of different sizes and are not easy to remove. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4As shown, a biological experimental culture dish rack includes a mounting plate 1, with mounting shells 2 fixedly connected to both sides of the mounting plate 1. A threaded rod 3 is provided inside the mounting shell 2, with one end of the threaded rod 3 penetrating to the outside of the mounting shell 2 and rotatably connected to the inner wall of the penetration point. This allows for easy rotation of the threaded rod 3 by the operator. A sleeve 4 is threadedly connected to the surface of the threaded rod 3. When the threaded rod 3 rotates, it can drive the sleeve 4 to move. The surface of the sleeve 4 is slidably connected to the inner wall of the mounting shell 2, and the top of the sleeve 4 is at the same horizontal level as the top of the mounting shell 2. This allows the sleeve 4 to move under the action of the threaded rod 3, while the inner wall of the mounting shell 2 acts as a guide for the movement of the sleeve. The sleeve 4 serves as a guide, preventing it from rotating in place due to the threads on the surface of the threaded rod 3. This effectively improves the stability of the sleeve 4 during movement. A bearing seat 12 is fixedly connected to the other end of the threaded rod 3, and the other side of the bearing seat 12 is fixedly connected to the inner wall of the mounting shell 2. This allows the bearing seat 12 to support the threaded rod 3 during rotation, preventing significant vibration and improving its stability. This also prevents instability during rotation from affecting the threaded connection with the sleeve 4. A fixing frame 5 is rotatably connected to the top of the sleeve 4. The fixing frame 5 has a U-shaped structure design, with two... Positioning rods 6 are fixedly connected to both sides. With the cooperation of the positioning rods 6 and the mounting plate 1, the culture dish can be formed into a triangular compression state, thereby limiting the position of the culture dish and preventing it from easily shifting. Furthermore, with the cooperation of the threaded rod 3 and the sleeve 4, the position of the positioning rods 6 can be adjusted, allowing the rack to accommodate culture dishes of different sizes, effectively improving its applicability. Positioning grooves 13 are provided on both sides of the mounting plate 1. The inner wall of the positioning grooves 13 has an arc-shaped structure design. This allows for simple limiting of the culture dish when it contacts the mounting plate 1, further improving the positioning effect of the rack. A connecting frame 7 is fixedly connected to the top of the fixed frame 5. The connecting frame 7 has an L-shaped structure design. A locking rod 8 is slidably connected to the inner cavity of the connecting frame 7. An adjustment mechanism 9 is installed on the top of the locking rod 8. A locking hole 10 is opened on the top of the sleeve 4. The inner wall of the locking hole 10 is slidably connected to the surface of the locking rod 8. Under this action, the locking rod 8 can be inserted into the locking hole 10 by the adjustment mechanism 9, thereby limiting the fixed frame 5 and preventing it from rotating easily. When it is necessary to remove all the culture dishes, the locking rod 8 can be released from the locking hole 10 by the adjustment mechanism 9. Then, the fixed frame 5 can be rotated by the positioning rod 6, so that the positioning rod 6 can remove all the culture dishes, making it convenient for staff to remove the culture dishes.

[0023] The adjustment mechanism 9 includes a movable frame 91 fixed to the top of the locking rod 8. A tension spring 92 is fixedly connected to the bottom of the movable frame 91, and the other end of the tension spring 92 is fixedly connected to the surface of the connecting frame 7. Under this action, when the operator needs to move the locking rod 8, the movable frame 91 provides an effective force application point, making it easier for the locking rod 8 to move. With the cooperation of the tension spring 92, the locking rod 8 can return to its original position after moving, and pressure is continuously applied to the locking rod 8, so that the locking rod 8 will not move easily when it is inside the locking hole 10, effectively improving the locking rod 8 during use. To improve stability, a connecting rod 93 is fixedly connected to one side of the bottom of the movable frame 91. The connecting rod 93 works in conjunction with the connecting frame 7. Under this action, after the locking rod 8 disengages from the locking hole 10, the movable frame 91 can be rotated to make the connecting rod 93 contact the connecting frame 7, thereby blocking the locking rod 8 and preventing the locking rod 8 from returning to its original position under the action of the tension spring 92. A limiting groove 11 is opened on one side of the top of the connecting frame 7. The inner wall of the limiting groove 11 is slidably connected to the surface of the connecting rod 93. Under this action, the connecting rod 93 can be limited, thereby preventing the connecting rod 93 from moving easily on the surface of the connecting frame 7 and effectively improving the stability of the connecting rod 93.

[0024] Working principle: First, the operator rotates the threaded rod 3 according to the culture dish to be placed. The thread on the surface of the threaded rod 3 can drive the sleeve 4 to move. With the cooperation of the sleeve 4, the fixing frame 5 can drive the positioning rod 6 to adjust until the positioning rod 6 is moved to the appropriate position, so that the placement rack can hold culture dishes of different sizes. Then, the culture dishes to be placed are placed between the mounting plate 1 and the positioning rod 6 in sequence to limit the culture dishes. When it is necessary to remove all the culture dishes, the operator can pull the movable frame 91 to disengage the locking rod 8 from the inside of the locking hole 10. Then, the operator rotates the movable frame 91 to make the connecting rod 93 insert into the inside of the limiting groove 11. Then, the operator directly rotates the positioning rod 6. Under the action of the positioning rod 6, the culture dish can be pushed so that the placement rack no longer limits the culture dish. After the culture dish is removed, the operator rotates the movable frame 91 to make the locking rod 8 insert into the inside of the locking hole 10.
