Description
Technical Field
[0001] The utility model relates to the technical field of bacterial culture equipment, and particularly relates to a bacterial culture dish for laboratory use. Background Technique
[0002] A culture dish is a laboratory ware used for culturing microorganisms or cells. It consists of a flat disc-shaped bottom and a cover, and is generally made of glass or plastic. The materials of the culture dish are basically divided into two categories, mainly plastic and glass. Glass ones can be used for plant materials, microbial culture and adherent culture of animal cells. Plastic ones may be made of polyethylene materials, and there are disposable and reusable ones, which are suitable for operations such as inoculation, streaking and separating bacteria in the laboratory, and can be used for the culture of plant materials.
[0003] The culture dish is an essential piece of equipment in the laboratory. When observing bacteria, users need to use the culture dish for culturing. However, since the culture dish is usually made of plastic materials and is equipped with a lid, when the user opens and closes the lid, due to the need to improve the sealing performance, some force is required, which easily causes the bacteria during the culturing process to fall off, reducing the safety of culturing with the culture dish, and the culture dish is prone to breakage during the cleaning process.
[0004] Therefore, we propose a bacterial culture dish for laboratory use. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bacterial culture dish for laboratory use to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A bacterial culture dish for laboratory use, including a culture dish body. At the top of the front surface of the culture dish body, a mounting seat is fixedly installed. At the top of the back surface of the culture dish body, a hinge is fixedly installed. At the top of the mounting seat, a connecting plate is fixedly installed. In the middle of the top of the connecting plate, a rotating seat is integrally connected. At both sides of the rotating seat on the top of the connecting plate, clamping springs are fixedly installed. Inside the rotating seat, a first clamping plate is rotatably connected. Inside the rotating seat, a second clamping plate is rotatably connected on one side of the first clamping plate. The top parts of the two clamping springs are respectively abutted and installed against the middle parts of the first clamping plate and the second clamping plate. The other end of the hinge is fixedly installed with a top cover. On the front surface of the top cover, a fixing convex block is integrally provided. At the bottom of the fixing convex block, a clamping cylinder is fixedly installed. The clamping cylinder is in clamping contact with the middle parts of the first clamping plate and the second clamping plate.
[0007] Optionally, the hinge is a spring hinge with a torsion spring, and the torsion spring in the hinge is arranged in the middle of the rotating shaft.
[0008] Optionally, symmetric arc surfaces are provided on the opposite surfaces of the first clamping plate and the second clamping plate, and the outer peripheral surface of the clamping cylinder is in tight contact with the arc surfaces of the first clamping plate and the second clamping plate.
[0009] Optionally, a pressing convex block is integrally connected to the middle parts outside the first clamping plate and the second clamping plate, and the top of the clamping spring is fixedly installed with the bottom of the pressing convex block.
[0010] Optionally, arc surfaces are provided on the tops of the first clamping plate and the second clamping plate, the tops of the first clamping plate and the second clamping plate do not contact each other, and the bottoms of the first clamping plate and the second clamping plate are rotatably arranged through a rotating shaft.

[0014] 1. For this laboratory bacterial culture dish, by setting the top cover, when using the culture dish body, close the top cover, so that the clamping cylinder is in tight contact with the tops of the first clamping plate and the second clamping plate, thereby causing the tops of the first clamping plate and the second clamping plate to deflect towards both sides, and then squeezing the clamping spring. After the clamping cylinder is clamped between the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate are pushed by the clamping spring to clamp the clamping cylinder tightly, fixing the top cover.

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 of 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] Please refer to Figures 1 to 5, the present utility model provides a bacterial culture dish for laboratory use, including a culture dish body 1. At the top of the front surface of the culture dish body 1, a mounting seat 4 is fixedly installed. At the top of the back surface of the culture dish body 1, a hinge 2 is fixedly installed. The hinge 2 is a spring hinge 2 with a torsion spring, and the torsion spring in the hinge 2 is arranged in the middle of the rotating shaft. At the top of the mounting seat 4, a connecting plate 5 is fixedly installed. In the middle of the top of the connecting plate 5, a rotating seat 6 is integrally connected. At the top of the connecting plate 5, clamping springs 10 are fixedly installed on both sides of the rotating seat 6. Inside the rotating seat 6, a first clamping plate 7 is rotatably connected. Inside the rotating seat 6, a second clamping plate 8 is rotatably connected on one side of the first clamping plate 7. The tops of the two clamping springs 10 are respectively tightly abutted and installed with the middle parts of the first clamping plate 7 and the second clamping plate 8. In the middle of the outside of the first clamping plate 7 and the second clamping plate 8, abutting protrusions 9 are integrally connected. The top of the clamping spring 10 is fixedly installed with the bottom of the abutting protrusion 9. The other end of the hinge 2 is fixedly installed with a top cover 3. On the front surface of the top cover 3, a fixing protrusion 13 is integrally arranged. At the bottom of the fixing protrusion 13, a clamping cylinder 14 is fixedly installed. The clamping cylinder 14 is in tight contact with the middle parts of the first clamping plate 7 and the second clamping plate 8. The diameter of the clamping cylinder 14 is greater than the minimum distance between the tops of the first clamping plate 7 and the second clamping plate 8. By setting the top cover 3, when using the culture dish body 1, close the top cover 3, so that the clamping cylinder 14 is in tight contact with the tops of the first clamping plate 7 and the second clamping plate 8, thereby causing the tops of the first clamping plate 7 and the second clamping plate 8 to deflect to both sides, and then squeezing the clamping springs 10. After the clamping cylinder 14 is clamped into the space between the first clamping plate 7 and the second clamping plate 8, the first clamping plate 7 and the second clamping plate 8 are pushed by the clamping springs 10 to clamp the clamping cylinder 14, fixing the top cover 3. When opening the top cover 3, just push the clamping cylinder 14 so that the clamping cylinder 14 slides out from between the first clamping plate 7 and the second clamping plate 8 to open the top cover 3. This increases the stability of the top cover 3, reduces the force used by the user during the opening and closing processes, reduces the risk of bacteria falling during the cultivation process, and increases the safety of the culture dish cultivation.
[0024] The opposite faces of the first clamping plate 7 and the second clamping plate 8 are provided with symmetric arc surfaces. The outer peripheral surface of the clamping cylinder 14 is in tight contact with the arc surfaces of the first clamping plate 7 and the second clamping plate 8. The tops of the first clamping plate 7 and the second clamping plate 8 are provided with arc surfaces, and the tops of the first clamping plate 7 and the second clamping plate 8 do not contact. The bottoms of the first clamping plate 7 and the second clamping plate 8 are rotatably arranged through a rotating shaft. The front and rear sides of the bottom of the first clamping plate 7 are integrally connected with limiting protrusions 11 facing the second clamping plate 8. The front and rear sides of the bottom of the second clamping plate 8 are provided with limiting grooves 12. The limiting protrusions 11 are slidably connected with the interiors of the limiting grooves 12. By providing the limiting protrusions 11 and the limiting grooves 12, after the clamping cylinder 14 slides out from between the first clamping plate 7 and the second clamping plate 8, under the action of the clamping spring 10, the tops of the first clamping plate 7 and the second clamping plate 8 approach each other, and the tops of the first clamping plate 7 and the second clamping plate 8 are prevented from closing by abutting against the bottoms of the limiting grooves 12 through the fiber protrusions, thereby affecting the clamping of the clamping cylinder 14.
[0025] Working principle:
[0026] When using the culture dish body 1, close the top cover 3 so that the clamping cylinder 14 is in tight contact with the tops of the first clamping plate 7 and the second clamping plate 8, thereby causing the tops of the first clamping plate 7 and the second clamping plate 8 to deflect to both sides, and then compressing the clamping spring 10. After the clamping cylinder 14 is clamped between the first clamping plate 7 and the second clamping plate 8, the first clamping plate 7 and the second clamping plate 8 are pushed by the clamping spring 10 to clamp the clamping cylinder 14 and fix the top cover 3. When opening the top cover 3, just push the clamping cylinder 14 so that the clamping cylinder 14 slides out from between the first clamping plate 7 and the second clamping plate 8 to open the top cover 3. This increases the stability of the top cover 3, reduces the force used by the user during the opening and closing processes, reduces the risk of bacteria falling during the culturing process, increases the safety of culturing in the culture dish. After the clamping cylinder 14 slides out from between the first clamping plate 7 and the second clamping plate 8, under the action of the clamping spring 10, the tops of the first clamping plate 7 and the second clamping plate 8 approach each other, and the tops of the first clamping plate 7 and the second clamping plate 8 are prevented from closing by abutting against the bottoms of the limiting grooves 12 through the fiber protrusions, thereby affecting the clamping of the clamping cylinder 14.
