Description

Technical Field

[0001] This utility model relates to a biochemical laboratory apparatus, specifically a liquid culture medium rack. Background Technology

[0002] Culture media are indispensable tools for microbial experiments. They provide a suitable growth environment for microorganisms, allowing these tiny life forms to thrive. Culture media not only contain the basic nutrients necessary for microbial life but also allow for selective cultivation by adding various components. Liquid culture media, often referred to as "broth" media, are known for their high fluidity and ease of handling.

[0003] In microbiology experiments, liquid culture media need to be placed in sterilized containers, and then the containers containing the liquid culture media are placed on racks for inoculation, cultivation and preservation of microorganisms.

[0004] However, conventional racks have fixed holes that can only hold one type of container, usually test tubes. But for different experimental purposes, different batches may choose containers with different diameters, which requires additional racks that match the hole size, undoubtedly increasing the cost of the experiment.

[0005] Therefore, how to provide a liquid culture medium rack that is both flexible and has stable clamping is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a liquid culture medium rack that can accommodate culture media of different diameters in batches, and is stable and not easily shaken.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a liquid culture medium holder, comprising:

[0008] The support frame is a rectangular structural frame;

[0009] A clamping plate assembly is disposed on the top of the bracket. The clamping plate assembly includes a fixed clamping plate and a sliding clamping plate. The fixed clamping plate and the sliding clamping plate are arranged vertically and stacked at their side ends. The fixed clamping plate and the sliding clamping plate are provided with a plurality of U-shaped clamping grooves at intervals at their corresponding stacked side ends. The fixed clamping plate is fixedly connected to the bracket, and the sliding clamping plate is slidably connected to the bracket and slides in the direction of the width of the corresponding U-shaped clamping groove. The U-shaped clamping groove of the sliding clamping plate cooperates with the U-shaped clamping groove of the fixed clamping plate on the side closer to it to clamp the two side walls of the culture medium container in the first direction.

[0010] A clamping plate assembly is disposed in the middle of the support. The clamping plate assembly includes two clamping plates that are close to or far apart from each other. The clamping plates are slidably connected to the support. The two clamping plates clamp the two side walls of the culture medium container in a second direction. The first direction is perpendicular to the second direction.

[0011] The technical advantages of this invention are: the clamping plate assembly achieves clamping of the culture medium container in the first direction, and the clamping plate assembly achieves clamping of the culture medium container in the second direction. The first direction and the second direction are perpendicular. Multi-directional clamping ensures the stability of the culture medium container. At the same time, it can also be used for batch clamping of products of different specifications, reducing investment costs and making it convenient to use.

[0012] Preferably, the relative movement of the sliding plate and the fixed plate changes the distance between the U-shaped grooves and the groove walls in the upper and lower stacked areas.

[0013] The resulting technical effect is that, during clamping, the culture medium container is held by one side of the sliding plate U-shaped groove and the other side of the fixed plate U-shaped groove. It can be understood that the clamping position is the opposite side of the upper and lower U-shaped grooves. Therefore, when the sliding plate is displaced, the distance between the opposite side of the upper and lower U-shaped grooves changes, thus adapting to the clamping of products with different diameters and specifications.

[0014] Preferably, the bottom side of the sliding plate is provided with a nut, and a screw is rotatably connected inside the nut. One end edge of the screw is provided with a positioning shaft section, and one end of the bracket is provided with a positioning hole. The positioning shaft section is rotatably located in the positioning hole, and a handle is provided at one end of the screw near the positioning shaft section.

[0015] The resulting technical effect is that the sliding plate moves by means of the cooperation between the screw and the nut. The screw is positioned on the rotating bracket through the positioning shaft section. When the screw is rotated, the nut will carry the sliding plate to move. The handle makes it convenient for personnel to use.

[0016] Preferably, the bracket has rail grooves at both ends in the middle, the end of the clamping plate has a slider that matches the rail groove, the bottom side of the two clamping plates has a nut, the nut is internally threaded with an adjusting rod, the adjusting rod has two threaded sections with opposite directions, and the threaded sections match the nut on the corresponding side.

[0017] The resulting technical effect is that the two clamping plates move closer or further apart through the cooperation of the nut and the double-threaded screw. The two clamping plates can achieve the second direction of clamping the culture medium container. The four clamping points in the first and second directions provide a stable clamping effect and are not easy to shake.

[0018] Preferably, the support also includes a tray, which is fixedly disposed at the lower part of the bracket, and the top surface of the tray is provided with an arc-shaped groove for supporting the bottom wall of the culture medium container.

[0019] The resulting technical effect is that the tray supports the culture medium container from below, thus stabilizing its placement.

[0020] Preferably, the sidewalls of the U-shaped slot are provided with flexible pads.

[0021] The resulting technical effect is that the flexible pad can prevent rigid damage to the container shell. Specifically, the flexible pad can be a silicone pad or a rubber pad.

[0022] Preferably, the sides of the clamping plates that are close to each other are provided with silicone pads or rubber pads.

[0023] The resulting technical effect is that the silicone and rubber pads on the clamps can prevent rigid damage to the container shell, which is generally made of glass and is fragile. Attached Figure Description
