Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for petri dishes, specifically to a petri dish placement rack. Background Technology

[0002] In laboratory environments, petri dish racks need to accommodate containers of different sizes. However, traditional racks often have a fixed structural design, and the connection between the guide rails and support components lacks flexibility, making it difficult to quickly adjust the height of the racks according to container dimensions. This not only limits the racks' applicability but can also lead to wasted space or operational inconvenience due to incompatible containers and racks. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a petri dish rack to solve the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A rectangular hollow base has two U-shaped inserts symmetrically arranged along its length at the top. Several placement plates are spaced apart along the height of the two U-shaped inserts on their sides, which are close to each other. Strip-shaped sliders are installed at both ends of each placement plate, and these sliders are slidably connected to guide rails. Two fixing blocks are spaced apart on the side of the guide rails away from the placement plates, and each fixing block has a sliding hole. Both sides of the U-shaped inserts are slidably connected to the sliding holes. Two parallel connecting posts are installed between the guide rails at both ends of the placement plates, and each connecting post has a sliding groove in its middle. A slider is slidably connected within each of the two sliding grooves, and a mounting block is installed at one end of each slider. A triangular height-adjusting plate is installed at the top of the rectangular hollow base, and the mounting block rests on the triangular height-adjusting plate.

[0006] As a preferred embodiment of the petri dish rack, a connecting rod is connected between the two U-shaped inserts, with the connecting rod located at the top of the U-shaped inserts. Vertically upward sliding tubes are installed around the inside of the rectangular hollow base. The bottom ends of the two U-shaped inserts pass through the upper surface of the rectangular hollow base and are inserted into the inner wall of the sliding tubes.

[0007] As a preferred embodiment of the petri dish rack, an internally threaded tube is installed between the sliding tube and the inner wall of the rectangular hollow base. The internally threaded tube communicates with the sliding tube. A fastening bolt is provided on the outer side of the rectangular hollow base. The fastening bolt passes through the side wall of the rectangular hollow base and is threadedly connected to the internally threaded tube. The length of the fastening bolt is greater than the length of the internally threaded tube, so that the fastening bolt can abut against the side wall of the U-shaped insert inside the sliding tube.

[0008] As a preferred embodiment of the petri dish rack, the slider is equipped with a lever, which is located between mutually parallel connecting posts and protrudes from the upper surface of the connecting posts.

[0009] As a preferred embodiment of the petri dish rack, the inclined surface of the triangular height adjustment plate has a stepped structure, and the mounting block is mounted on the stepped structure.

[0010] As a preferred embodiment of the petri dish rack, a first handle is installed on the front side of the rack.

[0011] As a preferred embodiment of the petri dish rack, the rectangular hollow base has a storage opening on the front side, a drawer is inserted into the inner wall of the storage opening, and a second handle is installed on the front side of the drawer.

[0012] The beneficial effects of this utility model are:

[0013] This utility model's petri dish rack adopts a stepped structure design. The guide rails at both ends of the placement plate are slidably connected to the U-shaped insert rod through sliding holes on the fixing block, allowing the placement plate to slide up and down along the U-shaped insert rod, thereby quickly adjusting the height of the placement plate. At the same time, the slider is driven by the lever to slide in the groove, so that the block at one end of the slider can be placed on any step position on the inclined surface of the triangular height adjustment plate, thereby positioning the placement plate to meet the placement needs of containers of different sizes. This not only avoids the limitation of container size on traditional fixed structures, but also improves space utilization. Attached Figure Description

[0027] Example 1:

[0028] like Figures 1 to 6 As shown, this embodiment provides a petri dish rack, including a rectangular hollow base 1. Two U-shaped inserts 2 are symmetrically arranged on the top of the rectangular hollow base 1 along its length. The tops of the two U-shaped inserts 2 are fixedly connected by connecting rods 3 to enhance overall stability. Vertically upward sliding tubes 4 are installed on all four sides of the interior of the rectangular hollow base 1. The bottom ends of the two U-shaped inserts 2 pass through the upper surface of the rectangular hollow base 1 and are inserted into the inner wall of the corresponding sliding tubes 4. The height of the U-shaped inserts 2 can be adjusted as needed to form a liftable support structure.

[0029] Meanwhile, an internally threaded tube 5 is installed between the sliding tube 4 and the inner wall of the rectangular hollow base 1. The internally threaded tube 5 is connected to the sliding tube 4, and a fastening bolt 6 is provided on the outer side of the rectangular hollow base 1. The fastening bolt 6 passes through the side wall of the rectangular hollow base 1 and is threadedly connected to the internally threaded tube 5. The length of the fastening bolt 6 is greater than the length of the internally threaded tube 5, so that the fastening bolt 6 can pass through the internally threaded tube 5 and abut against the side wall of the U-shaped insert 2 inside the sliding tube 4, thereby fixing the U-shaped insert 2. When the height of the U-shaped insert 2 needs to be adjusted, the operator can loosen the fastening bolt 6 and then adjust the height of the U-shaped insert 2. After the adjustment is completed, the fastening bolt 6 is tightened again to complete the height adjustment operation.

[0030] On the side of the two U-shaped rods 2 that are close to each other, several placement plates 13 are arranged at intervals along their height direction. Each of the left and right ends of the placement plate 13 is equipped with a strip slider 12. The strip slider 12 is slidably connected to a guide rail 9, so that the placement plate 13 can slide horizontally along the guide rail 9. On the side of the guide rail 9 away from the placement plate 13, two fixing blocks 10 are installed at intervals. The fixing blocks 10 are provided with sliding holes 11. Both sides of the U-shaped rods 2 are slidably connected to the sliding holes 11, so that the position of the placement plate 13 can be adjusted along the height direction of the U-shaped rods 2.

[0031] To ensure the stable fixation of the placement plate 13, a triangular height adjustment plate 20 is installed on the top of the rectangular hollow base 1 in this embodiment. The triangular height adjustment plate 20 is located at the rear end of the rectangular hollow base 1, and its inclined surface has a stepped structure. Simultaneously, two parallel connecting posts 15 are installed between the guide rails 9 at both ends of the placement plate 13. The connecting posts 15 are located at the rear end of the guide rails 9, and a groove 16 is provided in the middle of each of the two connecting posts 15. A slider 17 is slidably connected within each of the two grooves 16, and a mounting block 1 is installed at one end of the slider 17. 8. The mounting block 18 can be mounted on the triangular height adjustment plate 20. At the same time, the slider 17 is equipped with a lever 19. The lever 19 is located between the parallel connecting columns 15 and protrudes from the upper surface of the connecting columns 15. The operator can lift the lever 19 to drive the placement plate 13 on the guide rail 9 to move up and down. When the placement plate 13 moves to the appropriate height, the mounting block 18 is placed on the steps of the triangular height adjustment plate 20 of the same height to position the placement plate 13 to meet the placement requirements of petri dishes of different heights.

[0032] Example 2

[0033] Based on Embodiment 1, this embodiment optimizes the structure of the rectangular hollow base 1. The front side of the rectangular hollow base 1 has a storage opening 7, and a drawer 8 is inserted into the inner wall of the storage opening 7. The drawer 8 can be used to store experimental tools or spare items. At the same time, a second handle 21 is installed on the front side of the drawer 8, and a first handle 14 is installed on the front side of the placement plate 13 for easy pulling operation.

[0034] Working principle and usage process of this utility model:

[0035] When using this petri dish rack, the overall height of the petri dish rack can first be adjusted according to the height of the experimental platform. The operator loosens the fastening bolt 6, then pulls up the U-shaped insert 2, so that the U-shaped insert 2 slides in the sliding tube 4 to a suitable height, and then tightens the fastening bolt 6 again to fix the U-shaped insert 2, thereby adjusting the overall height of the petri dish rack.

[0036] Then, the operator can adjust the spacing between the placement plates 13 according to the height of the petri dish. The operator can manually lift the lever 19, which will move the placement plate 13 on the guide rail 9 up and down, thereby adjusting the placement plate 13 to the required height. Then, the lever 19 will drive the slider 17 to slide in the slide groove 16, placing the block 18 at one end of the slider 17 at a suitable step position on the inclined surface of the triangular height adjustment plate 20, thereby positioning the placement plate 13.

[0037] Finally, the operator can pull out the placement plate 13 through the first handle 14 to place the petri dish on the placement plate 13. When it is necessary to store tools or spare items, the second handle 21 can be pulled to open the drawer 8 for retrieval.

[0038] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
