Description

Technical Field

[0001] This invention relates to the field of storage technology, and in particular to a petri dish storage box. Background Technology

[0002] A culture 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. Culture dishes are basically divided into two categories: plastic and glass. Glass dishes can be used for plant material, microbial culture, and may also be used for adherent culture of animal cells. Plastic dishes, often made of polyethylene, are available in disposable and reusable versions, suitable for laboratory inoculation, streaking, and bacterial isolation procedures, and can be used for culturing plant material.

[0003] When storing culture dishes, they are often placed directly on culture trays. However, due to the adhesive nature of the storage, the trays cannot be stacked, which makes the culture dishes take up a lot of space. Furthermore, the culture dishes are often exposed to the outside and are often damaged by external forces, as well as affected by the external environment (light, temperature, etc.).

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a petri dish storage box and a storage component 100, which includes a storage box 101, a locking block 101a disposed on the outer wall of the storage box 101, a first slide rail 101b disposed on the inner wall of the storage box 101, a drawer 102 slidably disposed inside the first slide rail 101b, and an opening and closing door 103 rotatably disposed on the outer wall of the storage box 101.

[0035] The storage box 101 is a shell with an opening on one side. A locking block 101a is fixedly connected to the opening side of the storage box 101. The locking block 101a has a T-shaped structure. Three first slide rails 101b are arranged in an array on the inner wall of the storage box 101. The drawer 102 is a long plate. The opening and closing door 103 is rotatably connected to the outer wall of the storage box 101 on one side.

[0036] Preferably, the outer wall of the card block 101a is provided with a first inclined surface 101a-1, the end face of the drawer 102 is provided with a receiving box 102a, the outer wall of the receiving box 102a is provided with a limiting member 104, one end of the limiting member 104 is fixedly connected with a bidirectional threaded rod 105, the outer wall of the bidirectional threaded rod 105 is respectively provided with a first push plate 106 and a second push plate 107, and the two ends of the first push plate 106 are rotatably provided with a first support rod 106a, the two ends of the second push plate 107 are rotatably provided with a second support rod 107a, the other end of the first support rod 106a and the second support rod 107a are provided with a placement plate 108, and the end face of the placement plate 108 is provided with an array of connecting members 109.

[0037] A receiving box 102a is fixedly connected to the upper surface of drawer 102. A limiting member 104 is rotatably provided on the side of the receiving box 102a near the opening of storage box 101. The limiting member 104 can drive the bidirectional threaded rod 105 to rotate. The outer wall of the bidirectional threaded rod 105 has two sections of thread, and the directions of the two sections of thread are opposite. A first push plate 106 and a second push plate 107 are respectively connected to the outer walls of the two sections of thread. The inner wall of the first push plate 106, which contacts the bidirectional threaded rod 105, has a corresponding thread. Similarly, the inner wall of the second push plate 107 has a thread corresponding to the bidirectional threaded rod 105. When the bidirectional threaded rod 105 rotates, the first push plate 106 and the second push plate 107 move closer to each other or further away from each other; one end of the first support rod 106a is rotatably connected to the outer wall of the first push plate 106, and the other end is rotatably connected to the bottom of the placement plate 108; one end of the second support rod 107a is rotatably connected to the outer wall of the second push plate 107, and the other end is rotatably connected to the bottom of the placement plate 108, so that when the two push plates move closer to each other, the placement plate 108 can rise; if the two push plates move further away from each other, the placement plate 108 can be retracted into the receiving box 102a.

[0038] The limiting component 104 includes a knob 104a, one end of which extends into the interior of the receiving box 102a and is fixedly connected to the bidirectional threaded rod 105. A spring 104b is provided inside the knob 104a, and push rods 104c are provided at both ends of the spring 104b. A first limiting block 104c-1 is fixedly connected to the outer wall of the push rod 104c. A limiting plate 104d is slidably provided inside the knob 104a. Multiple through holes are provided on the outer wall of the receiving box 102a corresponding to the position of the knob. A second slide rail 104d-1 is provided inside the limiting plate 104d for the first limiting block 104c-1 to slide.

[0039] The knob 104a is a disc-shaped structure with a sliding space inside. A spring 104b is installed inside the sliding space, and push rods 104c are fixedly connected to both ends of the spring 104b. A first limiting block 104c-1 is fixedly connected to the outer wall of the push rod 104c. The through hole on the outer wall of the receiving box 102a is the same size as the limiting plate 104d, and the limiting plate 104d can slide into the through hole. The through holes are arranged in a circumferential array. The second slide rail 104d-1 is an inclined groove that simultaneously presses the push rods 104c. The two push rods 104c press the spring 104b. During the movement, the first limiting block 104c-1 slides along the inside of the second slide rail 104d-1, pulling the limiting plate 104d out of the through hole on the outer wall of the receiving box 102a. Then, rotating the knob 104 drives the bidirectional threaded rod 105 to rotate, thereby raising or lowering the placement plate 108.

[0040] The connector 109 includes a sphere 109a, a first movable groove 109a-1 for the sphere 109a, a second movable groove 109b on the outer wall of the sphere 109a, an airbag 109c at the bottom of the first movable groove 109a-1, a conical block 109d on the end face of the airbag 109c, a sliding abutment rod 109e inside the second movable groove 109b, and a rolling ball 109f inside the second movable groove 109b.

[0041] Among them, four spheres 109a are fixedly installed on the upper surface of the placement plate 108 and are distributed in the four corners; there is a first movable groove 109a-1 at the axial position of the sphere 109a, and an airbag 109c is fixed at the bottom of the first movable groove 109a-1. A conical block 109d is connected to the surface of the airbag 109c, and the outer wall of the conical block 109d is inclined; the first movable groove 109b connects the outside and the first movable groove 109a-1, and one end of the abutting rod 109e slides along the outer wall of the conical block 109d, while the other end abuts against the outer wall of the rolling ball 109f.

[0042] The first tray 301 is fixedly provided with a snap-fit ​​cylinder 109g on the side near the placement plate 108, and the inner wall of the snap-fit ​​cylinder 109g is provided with an annular groove 109g-1.

[0043] The bottom of the first tray 301 is fixedly connected to a snap-fit ​​cylinder 109g. The inner wall of the snap-fit ​​cylinder 109g has an annular groove 109g-1. When the snap-fit ​​cylinder 109g slides along the outer wall of the sphere 109a, the inner wall of the snap-fit ​​cylinder 109g pushes the rolling ball 109f to slide along the second movable groove 109b into the first movable groove 109a-1. The rolling ball 109f pushes the abutment rod 109e to slide. The abutment rod 109e slides along the outer surface of the conical block 109d, subsequently pushing the conical block 109d to compress the airbag 109c. When the rolling ball 109f slides along the inner wall of the snap-fit ​​cylinder 109g... When the ball reaches the annular groove 109g-1, the airbag 109c pushes the conical block 109d upward, pushing the contact rod 109e to push the ball 109f into the annular groove 109g-1. The outer wall of the ball 109f fits against the inner wall of the annular groove 109g-1, realizing quick release between the first tray 301 and the placement plate 108, making it convenient for the staff to pick up, put down and move the entire tray of culture dishes A. The function of the snap fastener 109 is to make the first tray 301 and the placement plate 108 shake, so as to prevent the first tray 301 from shaking during the handling process when the operator needs to transfer the storage box 101.

[0044] If only a single petri dish A needs to be observed or removed, the operator pulls out drawer 102, then presses the two push rods 104c, and then rotates knob 104a, causing the bidirectional threaded rod 105 to rotate, so that the first push plate 106 and the second push plate 107 move closer to each other, raising the placement plate 108 from the receiving box 102a. Then, the two push rods 104c are released, and spring 104b returns the two push rods 104c to their original positions. Then, the limiting plate 104d slides back into the through hole on the outer wall of the receiving box 102a, allowing the operator to operate on the placement plate 108, providing an operating platform for single placement and retrieval.

[0045] Example 2

[0046] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment is based on the previous embodiment. After long-term use, conventional flip-open doors may become loose or unable to close.

[0047] Preferably, the inner wall of the first sleeve 201 is provided with a limiting groove 201b, one end of the first sleeve 201 is provided with a third slide rail 201c, and the outer wall of the locking rod 202 near the locking block 101a is provided with a second inclined surface 202a.

[0048] The first sleeve 201 is embedded inside the opening and closing door 103. The first sleeve 201 is a through cylinder. Two rotating rods 201a are fixedly connected to the inner wall of the first sleeve 201. Each rotating rod 201a has a locking rod 202 rotatably provided on the outer wall. When the opening and closing door 103 is rotated, the first sleeve 201 inside the opening and closing door 103 will cover the locking block 101a. At the same time, the locking rod 202 is rotated, so that the opening and closing door 103 can no longer be rotated.

[0049] The inner wall of the first sleeve 201 is provided with a limiting groove 201b, and one end of the first sleeve 201 is provided with a third slide rail 201c. The outer wall of the locking rod 202 near the locking block 101a is provided with a second inclined surface 202a.

[0050] The first sleeve 201 has a turntable 203 at one end. The outer wall of the turntable 203 has a ring 203a that can slide along the inside of the third slide rail 201c. The turntable 203 has a first threaded rod 203b inside. The outer wall of the first threaded rod 203b is rotatably provided with a second sleeve 204.

[0051] Among them, a ring 203a is fixedly provided on the outer wall of the turntable 203. The outer diameter of the ring 203a is the same as the inner diameter of the third slide rail 201c, so that the ring 203a rotates and the turntable 203 rotates. Inside the turntable 203, there is a threaded column first threaded rod 203b. The outer wall of the first threaded rod 203b is threaded, and the inner wall of the second sleeve 204 has threads that mesh with the first threaded rod 203b.

[0052] A connecting plate 204a is fixedly provided at one end of the second sleeve 204 near the first sleeve 201. A pull block 205 is provided inside the first sleeve 201. A third support rod 205a is provided through the pull block 205, and the third support rod 205a extends through the connecting plate 204a to slide inside the limiting groove 201b.

[0053] The second sleeve 204 has a connecting plate 204a fixedly connected to one end near the inside. The connecting plate 204a has a Y-shaped structure. The pull block 205 is set between the connecting plates 204a. The third support rod 205a passes through the connecting plates 204a at both ends and extends into the corresponding limiting groove 201b to slide. When the turntable 203 rotates, the second sleeve 204 will move because the third support rod 205a slides along the limiting groove 201b, instead of rotating with the turntable 203. At the same time, since the third support rod 205a passes through the connecting plate 204a, the movement of the second sleeve 204 will drive the pull block 205 to move.

[0054] In summary, when the operator needs to operate on the culture dish A inside the storage box 101, rotating the turntable 203 pushes the second sleeve 204 inward, causing the pull block 205 to move inward, thereby releasing the pull block 205 from restricting the locking rod 202. Then, rotating the opening and closing door 103 outward causes the locking rod 202 to slide along the first inclined surface 101a-1. Subsequently, the locking rod 202 rotates around the rotating rod 201a, contacting the locking block 101a, opening the opening and closing door 103, and allowing operation on the culture dish A inside. When no operation is needed... When operating inside the storage box 101, the opening and closing door 103 is closed. If the locking rod 202 is not open at this time, the outer wall of the locking block 101a slides along the second inclined surface 202a, opening the locking rod 202. Then, when the opening and closing door 103 is closed, the turntable 203 is reversed, causing the pull block 205 to move outward, and at the same time causing the two locking rods 202 to rotate. The pull block 205 will abut against the locking rod 202 to prevent the locking rod 202 from rotating. The locking rod 202 clamps the locking block 101a to prevent the opening and closing door 103 from rotating, thus protecting the storage box 101.

[0055] Example 3

[0056] Reference Figures 1-9 This is the third embodiment of the present invention. This embodiment provides a protective structure for petri dish A, including a placement component 300, which includes a first tray 301, a first receiving groove 301a disposed inside the first tray 301, a cover plate 302 disposed on the end face of the first tray 301, a first disk 303 slidably disposed inside the first receiving groove 301a, and a clamping rod 304 rotatably disposed on the end face of the first disk 303.

[0057] The first tray 301 has the following structure: Figure 2 It is a cylindrical structure with one open end. Its first tray 301 has a cylindrical first receiving groove 301a at its bottom. The radius of the first disc 303 is the same as the inner diameter of the first receiving groove 301a. The first disc 303 can slide along the inner wall of the first receiving groove 301a. A clamping rod 304 is rotatably connected to the upper surface of the first disc 303, and four clamping rods 304 are arranged in a circumferential array. The clamping plate 304 is in the shape of a "hook," and the short side of the clamping plate 304 is tilted downwards. The culture dish A is placed... Place it on the upper surface of the first disc 303, then push the first disc 303 downward. Then the clamping rods 304 on the upper surface of the first disc 303 are pushed by the inner wall of the first receiving groove 301a. All four clamping rods 304 move closer to the culture dish A. During the rotation of the short side of the four clamping rods 304, they move downward and clamp the culture dish A. Then cover the culture dish A with the cover plate 302 to protect it. When it needs to be removed, open the cover plate 302 and drag the clamping rods 304 to release the clamping of the culture dish A.

[0058] Preferably, the end face of the first disc 303 is provided with a second receiving groove 303a, the inner wall of the second receiving groove 303a is provided with a first sliding groove 303a-1, a protrusion 303a-2 is fixedly provided inside the first sliding groove 303a-1, and a groove 303a-3 is provided on the outer wall of the protrusion 303a-2. The shape of the protrusion 303a-2 is the same as the shape of the first sliding groove 303a-1, and the protrusion 303a-2 and the first sliding groove 303a-1 form a sliding track.

[0059] The lower surface of the first disc 303 is provided with a second receiving groove 303a, which is rectangular. The left and right inner walls of the second receiving groove 303a are provided with a first sliding groove 303a-1, which is heart-shaped. A protrusion 303a-2 is fixedly connected to the bottom of the first sliding groove 303a-1. The upper end of the protrusion 303a-2 has a groove 303a-3. The shape of the protrusion 303a-2 is similar to that of the first sliding groove 103a-1. The protrusion 303a-2 and the first sliding groove 303a-1 form a closed-loop slide.

[0060] The third sleeve 301a-1 is located inside the first receiving groove 301a. A rotating rod 305 is rotatably provided inside the third sleeve 301a-1. A plate 305a is fixedly connected to the other end of the rotating rod 305. A first slider 305a-1 that can slide along the outer wall of the protrusion 303a-2 is fixedly connected to the outer wall of the plate 305a.

[0061] Two third sleeves 301a-1 are fixedly provided at the bottom of the first receiving groove 301a. A rotating rod 305 is rotatably provided between the two third sleeves 301a-1. The rotating rod 305 has a T-shaped structure, with one end rotating along the inside of the third sleeve 301a-1 and the other end extending into the inside of the second receiving groove 303a. A plate 305a is fixedly connected to one end of the rotating rod 305 near the first disc 303. The first slider 305a-1 on the outer wall of the plate 305a slides along the slide formed by the protrusion 303a-2 and the first slide groove 303a-1.

[0062] The first receiving groove 301a is provided with a first elastic element 306. One end of the first elastic element 306 is fixedly connected to the bottom of the first receiving groove 301a, and the other end of the first elastic element 306 is fixedly connected to the first disc 303.

[0063] The first elastic element 306 is a compression spring.

[0064] When the first disc 303 moves downward along the inner wall of the first receiving groove 301a, the first disc 303 begins to compress the first elastic element 306. At the same time, the first slider 305a-1 slides along the slide formed by the protrusion 303a-2 and the first sliding groove 303a-1, and the outer wall of the clamping rod 304 slides against the inside of the first receiving groove 301a and begins to rotate inward. When the first disc 303 can no longer be pushed, it means that the first slider 305a-1 has reached the uppermost end of the first sliding groove 303a-1 and then stops pushing. The first elastic element 306 will release some potential energy, and then the first slider 305a-1 will enter the bottom of the groove 303a-3, thereby restricting the sliding of the first disc 303. At this time, the clamping rod 304 clamps the culture dish A, and then the cover plate 302 is closed to store the culture dish A. The internal environment can maintain stable internal light and is not affected by changes in the external environment, while reducing air circulation with the outside and reducing external pollution. When it is time to remove petri dish A, approximately cover plate 302 is used. Then, the first disc 303 is pressed down, and the first slider 305a-1 slides out of the groove 303a-3. When the first disc 303 can no longer move down, the pressure is released, and the first elastic element 306 resets the first disc 303. The clamping rod 304 is then opened, and petri dish A can be removed.

[0065] Example 4

[0066] Reference Figures 7-8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that the clamping method of the culture dish A is changed so that the culture dish A is clamped outside the first receiving groove 301a.

[0067] Preferably, a support column 401 is provided on the end face of the first disk 303. A first placement disk 401a is fixedly connected to the outer wall of the support column 401 near one end of the first disk 303. A second placement disk 401b is fixedly connected to the outer wall of the other end of the support column 401. A second sliding groove 401b-1 is arranged in an array inside the second placement disk 401b. A sliding disk 402 is slidably provided on the outer wall of the support column 401. A third inclined surface 402a is provided on the end face of the sliding disk 402, which allows the clamping rod 304 to slide. A platform 402b is provided on the end face of the sliding disk 402. A second slider 402b-1 is arranged in an array on the outer wall of the platform 402b. A second elastic element 403 is sleeved on the outer wall of the support column 401. The second elastic element 403 is disposed between the sliding disk 402 and the first placement disk 401a.

[0068] The first disk 303 has a detachable support column 401 on its upper surface. A first placement disk 401a is fixedly connected to the outer wall of the support column 401. The radius of the first placement disk 401a is smaller than the radius of the first disk 303. A second placement disk 401b fixed to the outer wall of the support column 401 has a second sliding groove 401b-1 running through its interior. The second sliding groove 401b-1 is an arc-shaped groove, and its trajectory is directed towards the axis of the support column 401. A sliding disk 402 is slidably mounted on the outer wall of the support column 401. The upper surface is an inclined plane, and the upper surface of the slide 402 is also provided with a platform 402b. The platform 402b is a ring structure, and two second sliders 402b-1 are arranged in a circular array on the outer wall of the platform 402b. The outer wall of the support column 401 is fitted with a second elastic element 403, which is a compression spring and is fitted between the slide 402 and the first placement plate 401a. When the slide 402 moves downward, it will squeeze the second elastic element 403. At the same time, when there is no downward force, the second elastic element 403 will reset the slide 402.

[0069] The outer wall of the support column 401 is provided with a second disk 404, the inner wall of the second disk 404 is provided with a third groove 404a for the second slider 402b-1 to slide, and the interior of the second disk 404 is provided with a vertical groove 404b.

[0070] The second disk 404 is positioned between the sliding disk 402 and the second placement disk 401b. The second disk 404 can rotate on the outer wall of the support column 401. It can be rotatably connected by a circular groove on the inner wall of the second disk 404 and a fixed frustum on the outer wall of the support column 401. A portion of the second disk 404 is attached to the outer wall of the platform 402b. A third sliding groove 404a is provided on the inner wall of the second disk 404. The third sliding groove 404a is an inclined groove. Since the second disk 404 rotates, when the sliding disk 402 moves downward, its platform 402b will also move downward. At the same time, the second slider 402b-1 on the outer wall of the platform 402b slides along the third sliding groove 404a. Since the second disk 404 cannot descend, the second slider 402b-1 will push the second disk 404 to rotate as it moves downward.

[0071] The second placement plate 401b has a clamping plate 405 on its end face array. The end face of the clamping plate 405 has a first limiting rod 405a. The first limiting rod 405a extends through the vertical groove 404b and slides inside the second sliding groove 401b-1.

[0072] The upper surface of the second placement plate 401b is slidably provided with four clamping plates 405. The four clamping plates 405 have a fan-shaped structure, and the lower surface of the clamping plates 405 is fixedly connected with a first limiting rod 405a. The first limiting rod 405a extends through the vertical groove 404b into the interior of the second sliding groove 401b-1. When the second disc 404 rotates, the first limiting rod 405a on the lower surface of the clamping plate 405 will slide along the interior of the second sliding groove 401b-1. At the same time, due to the restriction of the vertical groove 404b, the clamping plates 405 will move closer to each other. If the second disc 404 is flipped, the clamping plates 405 will move further apart.

[0073] In summary, the first placement plate 401a below the support column 401 is placed on the upper surface of the first disc 303, and the culture dish A is placed on the upper surface of the second placement plate 401b. Then, the second placement plate 401b is pressed down, causing it to push the first disc 303 downwards along the inner wall of the first receiving groove 301a. As the first slider 305a-1 on the outer wall of the upper plate 305a of the rotating rod 305 slides into the groove 303a-3, the clamping rod 304 rotates along the inner wall of the first receiving groove 301a around the rotation point. Simultaneously... The upper end of the clamping rod 304 begins to slide along the surface of the third inclined plane 402a, pushing the slide plate 402 downward and squeezing the second elastic element 403. At this time, the second slider 402b-1 on the outer wall of the platform 402b slides along the inside of the third slide groove 404a, causing the second disc 404 to rotate. At the same time, it causes the clamping plates 405 on the upper surface of the second placement plate 401b to move closer together, clamping the culture dish A. The outer wall of the culture dish A is clamped, preventing it from sliding into the inside of the first receiving groove 301a, thus avoiding the inability of internal sterilization light to irradiate the culture dish A.

[0074] When it is necessary to remove petri dish A, open the cover plate 302, press down the first placement plate 401a, push the first disc 303 down, and the first slider 305a-1 on the outer wall of the rotating rod 305 slides out of the groove 303a-3. Then the first elastic member 306 pushes the first disc 303 out of the first receiving groove 301a. Then the second elastic member 403 pushes the clamping rod 304 to slide along the third inclined surface 402a. Then the clamping rod 304 opens, the sliding plate 402 moves upward, pushes the second disc 404 to reverse, and the clamping plates 405 move away from each other, and the petri dish A is released from clamping.

[0075] Example 5

[0076] Reference Figures 1-9 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a sampling channel is added to prevent the internal environment of the first tray 301 and the cover plate 302 from being damaged.

[0077] Preferably, the end face of the cover plate 302 is provided with a slide cylinder 501, the slide cylinder 501 is connected to the interior of the cover plate 302, the outer wall of the slide cylinder 501 is provided with a first movable channel 501a, and the outer wall of the first movable channel 501a is provided with a second movable channel 501a-1.

[0078] A sliding cylinder 501 is fixedly connected to the upper surface of the cover plate 302. The sliding cylinder 501 is a cylindrical channel open at both ends, with one end connected to the interior of the cover plate 302. Two first movable channels 501a are symmetrically provided on the outer wall of the sliding cylinder 501, and each of the two first movable channels 501a is connected to a second movable channel 501a-1, such as... Figure 1 As shown.

[0079] A sampling rod 502 is slidably provided inside the slide cylinder 501. The outer wall of the sampling rod 502 is provided with a slot 502a. The end of the sampling rod 502 near the first tray 301 is provided with a third movable channel 502b. A first limiting ring 502b-1 is fixedly provided on the inner wall of the third movable channel 502b, and a second limiting ring 502b-2 is fixedly provided on the inner wall of the third movable channel 502b.

[0080] The inner wall of the slide cylinder 501 is slidably provided with a sampling rod 502. The size of the sampling rod 502 is adapted to the inner diameter of the slide cylinder 501. The lower surface of the sampling rod 502 has a third movable channel 502b. The third movable channel 502b is cylindrical. The inner wall of the third movable channel 502b is fixedly provided with a first limiting ring 502b-1. A second limiting ring 502b-2 is above the first limiting ring 502b-1, and the inner diameter of the second limiting ring 502b-2 is larger than the inner diameter of the first limiting ring 502b-1.

[0081] A second limiting rod 503 is slidably provided inside the first active channel 501a. A second limiting block 503a is provided on the outer wall of the second limiting rod 503, which can slide along the inside of the second active channel 501a-1. One end of the second limiting rod 503 can slide along the outer wall of the sampling rod 502, and the other end is fixedly provided with a handle 503b. A third elastic element 504 is sleeved on the outer wall of the sampling rod 502.

[0082] The first movable channel 501a has a second limiting rod 503 sliding inside it. A second limiting block 503a, identical in shape to the second movable channel 501a-1, is fixedly connected to the outer wall of the second limiting rod 503. Pulling the handle 503b pulls the second limiting rod 503 outwards. When the second limiting block 503a slides out of the second movable channel 501a-1, rotating the second limiting rod 503 rotates the second limiting block 503a on its outer wall by a certain angle, causing it to abut against the outer wall of the slide cylinder 501. The second limiting block 503a restricts the second limiting rod 503 from sliding inwards. The third elastic element 504 is a compression spring, always in a stretched state. One end of the third elastic element 504 is fixedly connected to the handle 504b, and the other end is fixedly connected to the outer wall of the slide cylinder 501.

[0083] In summary, the sampling rod 502 slides downward through the inner wall of the slide cylinder 501. When the first limiting ring 502b-1 contacts the upper surface of the clamping plate 405, it continues to be pushed downward and then released. The first disc 303 slides out of the first receiving groove 301a, and then the clamping rod 304 contacts the restriction on the slide disc 402. Under the action of the second elastic element 403, the slide disc 402 drives the second disc 404 to rotate. Then the clamping plate 405 moves outward. At this time, the clamping disc 405 will be locked into the track formed between the first limiting ring 502b-1 and the second limiting ring 502b-2. Then the sampling rod 502 is pulled upward, and the sampling rod 502 will move the clamping plate 405 upward, while driving the support column 401 to move upward.

[0084] When the slot 502a on the outer wall of the sampling rod 502 slides past the first movable channel 501a, the second limiting rod 503 is rotated, aligning the second limiting block 503a on the outer wall of the second limiting rod 503 with the second movable channel 501a-1. Then, the third elastic element 504 pushes the second limiting rod 503 to slide inward, continuing to pull out the sampling rod 502. The second limiting rod 503 slides along the outer wall of the sampling rod 502, and then the second limiting rod 503 disengages from the outer wall of the sampling rod 502, entering the space between the sliding plate 402 and the second disc 404. The second limiting rod 503 holds the second disc 404. If only the condition of the internal culture dish A needs to be observed, it can be observed through the observation window. If it needs to be removed, squeeze both second limiting rods 503 simultaneously. Then, the second limiting rods 503 slide along the third inclined surface 402a, separating the sliding plate 402 from the second disc 404. This causes the clamping plates 405 to move closer together and slide out of the track formed between the first limiting ring 502b-1 and the second limiting ring 502b-2. Then, take out the sampling rod 502, release the second limiting rods 503, and release the clamping plates 405 from the culture dish A, so that the culture dish A can be removed.

[0085] If a new petri dish A needs to be placed, squeeze the second limiting rod 503 to slide the sampling rod 502 into the interior of the slide cylinder 501. Then release the second limiting rod 503, and the clamping plate 405 re-clamps into the sampling rod 502. Then pull out the second limiting rod 503 to clamp the second limiting block 503a onto the outer wall of the slide cylinder 501. Press down the sampling rod 502 to bring the first placement plate 401a on the outer wall of the support column 401 against the upper surface of the first disk 303. Then push the sampling rod 502 to clamp the first slider 305a-1 into the groove 303a-3. The clamping rod 304 drives the sliding plate 402 to move downward, causing the clamping plate 405 to clamp the culture dish A. Then, the second limiting rod 503 is rotated to realign the second limiting block 503a with the second active channel 501a-1. The second limiting rod 503 then slides along the outer wall of the sampling rod 502. When the sampling rod 502 is pulled out, the second limiting rod 503 slides into the slot 502a, restricting the sliding of the sampling rod 502 and blocking the sliding cylinder 501. This prevents the external environment from exchanging with the internal environment of the first tray 301, which would alter the internal light and environment and affect the culture dish A.

[0086] This not only prevents the external environment from affecting culture dish A, but also reduces the exchange between the external and internal environments when observing culture dish A. At the same time, it can clamp culture dish A when it is placed to prevent it from tilting or other issues.
