Description

Technical Field

[0001] This utility model relates to the technical field of storage and transportation of petri dishes, and in particular to a stacking rack for petri dishes. 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 typically made of glass or plastic.

[0003] In laboratories, experiments typically require the use of batches of petri dishes. Experimental equipment includes stacking racks for storing or placing these batches, and marking machines for labeling and transporting them. However, existing stacking racks generally place petri dishes from the top. When these dishes are placed from the side, the overall stability of the batch is poor, and there is a risk of them tipping over. Summary of the Invention

[0004] The purpose of this invention is to improve the problem of the risk of lateral tilting when a batch of culture dishes enters from the side in existing stacking racks, and to provide a stacking rack for culture dishes.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] Stacking racks for petri dishes include:

[0007] The support body includes a first support plate, a second support plate, and at least three support columns. The two ends of each support column are respectively installed on the first and second support plates. The three support columns are distributed along the circumference of the first support plate, and a material cavity is formed between the three support columns. The culture dish is housed in the material cavity.

[0008] The limiting component is movably mounted on the first support plate or the second support plate, and the limiting component is disposed between the first support plate and the second support plate; wherein, a feed inlet is formed between the two support columns near the limiting component, and the feed inlet is in communication with the material cavity; the limiting component has a first moving position and a second moving position, in the first moving position, the limiting component is close to the feed inlet; in the second moving position, the limiting component is away from the feed inlet.

[0009] In one embodiment, the limiting component includes a first limiting member and a second limiting member, the two ends of the first limiting member being movably mounted on a first support plate and a second support plate, the two ends of the second limiting member being movably mounted on the first support plate and the second support plate, and the first limiting member and the second limiting member being disposed opposite to each other.

[0010] The first limiting member and the second limiting member have a moving path that moves closer to or further away from each other; when the first limiting member and the second limiting member move closer to each other, the feed inlet narrows; when the first limiting member and the second limiting member move further away from each other, the feed inlet widens.

[0011] In one embodiment, the first or second limiting member includes a limiting rod, a first connecting block, and a second connecting block. The two ends of the limiting rod are respectively installed on the first ends of the first connecting block and the second connecting block. The second end of the first connecting block is rotatably connected to the first support plate, and the second end of the second connecting block is rotatably connected to the second support plate.

[0012] The limiting rod has a clockwise or counterclockwise movement path.

[0013] In one embodiment, the first or second limiting member further includes an abutment block and an elastic member. The first end of the elastic member is installed inside the first connecting block, the abutment block is at least partially located inside the first connecting block, and the first end of the abutment block abuts against the second end of the elastic member, and the second end of the abutment block abuts against the bottom of the first support plate.

[0014] In one embodiment, the end of the abutment block near the first support plate is spherical, and the outer arc surface of the abutment block abuts against the lower end surface of the first support plate.

[0015] In one embodiment, the second support plate has a limiting groove that extends along the movement path of the limiting rod;

[0016] The bottom of the second connecting block has a limiting block, which is at least partially located in the limiting groove and is used to abut against the inner wall of the second support plate.

[0017] In one embodiment, the support body further has a base, which is mounted on the bottom of the second support plate;

[0018] The base has a placement groove and a through-hole, the through-hole being located at the bottom of the base and communicating with the material cavity.

[0019] In one embodiment, the base is at least partially bent and bent to form a placement groove, the height of which corresponds to the height of the petri dish.

[0020] In one embodiment, both the first support plate and the second support plate have notches, and the opening direction of the notches is consistent with the opening direction of the placement groove.

[0021] In one embodiment, the support column has four columns, which are equidistantly distributed around the first support plate.

[0022] The technical solution provided by this utility model has the following advantages and effects:

[0023] When a culture dish needs to be placed, the limiting component moves to the second moving position, and the culture dish can enter the material chamber from the feed inlet; after the culture dishes are placed, multiple culture dishes are stacked in the material chamber, and the limiting component moves to the first moving position. The limiting component is used to abut against the culture dishes in the material chamber and support the culture dishes from the side of the support body, thereby improving the stability of multiple culture dishes in the material chamber.

[0036] This utility model proposes a stacking rack 100 for petri dishes 3, such as... Figures 1 to 4 As shown, the system includes a support body 1 and a limiting component 2. The support body 1 includes a first support plate 11, a second support plate 12, and at least three support columns 14. The two ends of the support columns 14 are respectively installed on the first support plate 11 and the second support plate 12. The three support columns 14 are distributed circumferentially along the first support plate 11, and a material cavity 16 is formed between the three support columns 14, in which the culture dish 3 is housed. The limiting component 2 is movably installed on the first support plate 11 or the second support plate 12, and the limiting component 2 is located between the first support plate 11 and the second support plate 12. An inlet 15 is formed between the two support columns 14 on the side closest to the limiting component 2, and the inlet 15 communicates with the material cavity 16. The limiting component 2 has a first moving position and a second moving position. In the first moving position, the limiting component 2 is close to the inlet 15. In the second moving position, the limiting component 2 is away from the inlet 15.

[0037] Specifically, multiple culture dishes 3 can be placed in the material cavity 16 through the opening on the first support plate 11. An inlet 15 is formed between the two support columns 14 near the limiting component 2, allowing the culture dishes 3 to enter the material cavity 16 from different directions, thus improving the transport efficiency of the culture dishes 3. Since the overall stability of multiple culture dishes 3 is poor after stacking, a movable limiting component 2 is provided at the inlet 15. When a culture dish 3 needs to be placed, the limiting component 2 moves to a second moving position, allowing the culture dish 3 to enter the material cavity 16 from the inlet 15. After all the culture dishes 3 have been placed, they are stacked in the material cavity 16, and the limiting component 2 moves to a first moving position. The limiting component 2 then abuts against the culture dishes 3 in the material cavity 16, supporting the culture dishes 3 from the side of the support body 1, thus improving the stability of the multiple culture dishes 3 in the material cavity 16.

[0038] In one embodiment, the limiting component 2 includes a first limiting member 21 and a second limiting member 22. The two ends of the first limiting member 21 are movably mounted on the first support plate 11 and the second support plate 12, and the two ends of the second limiting member 22 are movably mounted on the first support plate 11 and the second support plate 12, with the first limiting member 21 and the second limiting member 22 arranged opposite to each other. The first limiting member 21 and the second limiting member 22 have a moving path that allows them to move closer to each other or further away from each other. When the first limiting member 21 and the second limiting member 22 move closer to each other, the feed inlet 15 narrows; when the first limiting member 21 and the second limiting member 22 move further away from each other, the feed inlet 15 widens.

[0039] Specifically, the first limiting member 21 and the second limiting member 22 have a moving path that moves closer to or further away from each other; when it is necessary to place the culture dish 3, the first limiting member 21 and the second limiting member 22 move further away from each other, and the feed inlet 15 increases, so that the culture dish 3 can enter the material cavity 16 through the feed inlet 15; when the culture dish 3 is placed, the first limiting member 21 and the second limiting member 22 move closer to each other, and the size of the feed inlet 15 decreases, so that the first limiting member 21 and the second limiting member 22 support multiple culture dishes 3 on the side of the supporting body 1, further improving the stability of multiple culture dishes 3 in the material cavity 16.

[0040] Preferably, the first limiting member 21 or the second limiting member 22 includes a limiting rod 211, a first connecting block 212, and a second connecting block 214. The two ends of the limiting rod 211 are respectively installed at the first ends of the first connecting block 212 and the second connecting block 214. The second end of the first connecting block 212 is rotatably connected to the first support plate 11, and the second end of the second connecting block 214 is rotatably connected to the second support plate 12. The limiting rod 211 has a clockwise or counterclockwise movement path. Specifically, the two ends of the limiting rod 211 are connected to the first connecting block 212 and the second connecting block 214, enabling the two ends of the limiting rod 211 to rotate with the first support plate 11 and the second support plate 12 respectively. The limiting rod 211 has a clockwise or counterclockwise movement path via the first connecting block 212 and the second connecting block 214. By moving the limiting rod 211, the limiting rod 211 can have a first moving position and a second moving position.

[0041] To improve the stability of the first limiting member 21 and the second limiting member 22 in a static state, preferably, the first limiting member 21 or the second limiting member 22 further includes an abutment block 213 and an elastic member. The first end of the elastic member is installed inside the first connecting block 212, and the abutment block 213 is at least partially located inside the first connecting block 212. The first end of the abutment block 213 abuts against the second end of the elastic member, and the second end of the abutment block 213 abuts against the bottom of the first support plate 11. Specifically, when the limiting rod 211 rotates, the abutment block 213 abuts against the first support plate 11, but the abutment block 213 flexibly contacts the first support plate 11 through the elastic member. When the external force driving the limiting rod 211 disappears, the force of the elastic member acts on the first support plate 11 through the abutment block 213, and the limiting rod 211 maintains a relatively stable state when there is no external force. Furthermore, the weight of the multiple culture dishes 3 is sequentially transferred to the second support plate 12, resulting in relatively low lateral pressure on the culture dishes 3. Therefore, the lateral pressure of the culture dishes 3 makes it difficult to move the limiting rod 211. When the limiting rod 211 is moved, the elastic force generated by the elastic element is limited, thus it does not lead to difficulty in driving the limiting rod 211 to move.

[0042] Preferably, the end of the abutment block 213 near the first support plate 11 is spherical, and the outer arc surface of the abutment block 213 abuts against the lower end surface of the first support plate 11. Specifically, by having the outer arc surface of the abutment block 213 contact the lower end surface of the first support plate 11, the contact area between the abutment block 213 and the first support plate 11 can be reduced, thereby reducing the friction between the abutment block 213 and the first support plate 11 and reducing the force required to drive the limiting rod 211 to move.

[0043] To improve the stability and range of movement of the limiting rod 211, preferably, the second support plate 12 has a limiting groove 121 extending along the movement path of the limiting rod 211; the bottom of the second connecting block 214 has a limiting block 215, which is at least partially located within the limiting groove 121 and abuts against the inner wall of the second support plate 12. Specifically, the limiting groove 121 is provided on the second support plate 12, and the limiting block 215 cooperates with the limiting groove 121 to restrict the rotation path of the second connecting block 214. The limiting block 215 can improve the stability of the limiting rod 211 during movement. Moreover, by setting the limiting groove 121, the movement range of the limiting rod 211 can be limited, preventing the abutting block 213 on the first connecting block 212 from separating from the first support plate 11. The first connecting block 212, through the abutting block 213 and the elastic element, always maintains abutting state with the first support plate 11, thereby improving the stability of the limiting rod 211.

[0044] To facilitate the transport of the culture dishes 3 within the material chamber 16, preferably, the support body 1 also has a base 13, which is mounted on the bottom of the second support plate 12. The base 13 has a placement groove 131 and a through-hole 132, with the through-hole 132 located at the bottom of the base 13 and communicating with the material chamber 16. Specifically, the picking claw can grip a single culture dish 3 through the through-hole 132 and remove the single culture dish 3 from the outlet of the placement groove 131, improving the convenience of transporting the culture dishes 3. Moreover, multiple culture dishes 3 can enter from the inlet 15 and exit from the outlet of the placement groove 131. The base 13 supports multiple culture dishes 3, and there is no interference between the entry and exit of the culture dishes 3 from the stacking rack 100, greatly improving the practicality of the stacking rack 100.

[0045] Preferably, the base 13 is at least partially bent, forming a placement groove 131, the height of which corresponds to the height of the petri dish 3. Specifically, the petri dish 3 enters the material chamber 16 through the feed inlet 15 and exits through the placement groove 131. Depending on the processing requirements of the petri dish 3, the placement groove 131 holds only a single petri dish 3. When the picking claw picks up the petri dish 3, it removes the single petri dish 3 from the material chamber 16, facilitating the transport and processing of the petri dish 3. After the single petri dish 3 is removed by the picking claw, multiple petri dishes 3 move downwards due to their own weight, causing the bottommost petri dish 3 to enter the placement groove 131 for easy picking by the picking claw.

[0046] Preferably, both the first support plate 11 and the second support plate 12 have notches, and the opening direction of the notches is consistent with the opening direction of the placement groove 131. Specifically, the notches in the first support plate 11 and the second support plate 12 facilitate the entry of the petri dish 3 from the top of the support body 1, thereby improving the flexibility of the petri dish 3 entering the stacking rack 100.

[0047] Preferably, there are four support columns 14, which are equidistantly distributed around the first support plate 11. Specifically, by using four support columns 14, the inner walls of the support columns 14 abut against the culture dish 3, which can improve the stability of the culture dish 3 within the material cavity 16.
