Description

Technical Field

[0001] This utility model relates to the field of culture dish holder technology, and in particular to a holder for stem cell culture dishes. Background Technology

[0002] Petri dishes are common laboratory equipment used for culturing microorganisms or cells. They are typically made of transparent glass or plastic, and are round, shallow dishes with a flat bottom to facilitate observation of the culture's growth. Their design aims to provide a suitable environment to promote the reproduction of microorganisms or cells and for experimental research. Petri dish holders are auxiliary devices used to stably hold multiple petri dishes, ensuring they remain horizontal during experiments and preventing liquid spillage or cross-contamination.

[0003] According to the Chinese patent "Support for Fixing Culture Dishes" authorized announcement number "CN218478745U", this utility model has a compact and novel structure, which is used for the stable placement of culture dish bodies and makes it easy to pick up the corresponding culture dish bodies, avoiding the tipping of stacked culture dish bodies. It is more stable, convenient and flexible to use, and is mainly used as a support for culture dishes.

[0004] The aforementioned application avoids stacking of culture dishes by rotating the support plate to the column. However, due to the ring design, the culture dishes need to be picked up from the edge by the staff each time they are placed on or removed from the support. This can easily cause microorganisms to adhere to the edge of the culture dishes, thus affecting the experimental results.

[0005] Therefore, a fixture for stem cell culture dishes is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a holder for stem cell culture dishes in order to solve the above-mentioned problems, thereby improving the problem of easy contamination of culture dishes when they are handled.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a fixing frame for stem cell culture dishes, comprising: a vertical rod, the bottom end of which is fixedly connected to a support base;

[0008] The placement mechanism includes multiple placement platforms rotatably connected to a surface. Two clamping blocks are provided on the surface of each placement platform, and the bottom ends of the two clamping blocks are slidably connected to the inner wall of the placement platform. A sliding plate is provided inside the placement platform, and a support seat is provided above the sliding plate.

[0009] Preferably, the placement platform has a sliding groove inside, the sliding plate is disposed in the sliding groove and slidably connected to the inner wall of the placement platform, the support seat is fixedly connected to the upper surface of the sliding plate, and grooves are formed on both sides of the support seat. This drives the support platform to move.

[0010] Preferably, both clamping blocks are semi-circular blocks, arranged opposite to each other, with an arc-shaped block fixedly connected to one end of each clamping block. This secures the culture dish.

[0011] Preferably, a sliding rod is fixedly connected to the bottom end of the clamping block, and a spring is fixedly connected between the bottom end of the clamping block and the inner wall of the placement platform. The spring is sleeved around the sliding rod, and the sliding rod is slidably connected to the inner wall of the placement platform. This increases the stability of the clamping block in fixing the culture dish.

[0012] Preferably, a push rod is slidably connected to the inner wall of the placement platform, with one end of the push rod positioned within a groove and the other end extending through the placement platform. This reduces the time that hands are in contact with the culture dishes during placement and removal, thus lowering the probability of contamination.

[0013] Preferably, a baffle plate is fixedly connected to the bottom end of the clamping block, and the baffle plate is slidably connected to the inner wall of the placement platform, and the baffle plate is positioned above the sliding rod. This prevents contaminants from accumulating on the placement platform.

[0014] Preferably, a handle is fixedly connected between the support base and the top of the slide rod, and the distance from the handle to the slide rod is less than the length of the placement platform. This facilitates the movement of the mounting bracket.

[0015] The beneficial effects of this utility model are:

[0016] By placing the support base above the slide plate and using the push rod, when placing the culture dish on the fixed rack, the culture dish is placed directly on the support base. Then, the slide plate and the support base fix the culture dish in the clamp or push it out of the clamp. This reduces the time and number of times the hand comes into contact with the edge of the culture dish during the process of picking up and putting the culture dish on the fixed rack, thus reducing the probability of the culture dish being contaminated due to the operation of the staff.

[0017] By using clamps in conjunction with the support base, when placing the culture dish on the fixed rack, the clamps and springs increase the pressure on the culture dish placed on the support base, making it more stable on the fixed rack; by rotating the placement platform onto the upright, the culture dishes can be prevented from being stacked when placed on the fixed rack, reducing the probability of contamination.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-5 As shown, the holder for the stem cell culture dish includes: a support rod 100, and a support base 110 is fixedly connected to the bottom end of the support rod 100;

[0026] The placement mechanism 300 includes a plurality of placement platforms 310 rotatably connected to a surface. Two clamping blocks 320 are provided on the surface of the placement platform 310. The bottom ends of the two clamping blocks 320 are slidably connected to the inner wall of the placement platform 310. A slide plate 340 is provided inside the placement platform 310, and a support seat 330 is provided above the slide plate 340.

[0027] like Figure 3 , Figure 4 and Figure 5As shown, the placement platform 310 has a groove 311 inside. The slide plate 340 is set in the groove 311 and is slidably connected to the inner wall of the placement platform 310. The support seat 330 is fixedly connected to the upper surface of the slide plate 340. The support seat 330 has grooves on both sides. The two clamping blocks 320 are semi-circular blocks and are arranged opposite to each other. One end of the clamping block 320 is fixedly connected to an arc-shaped block 321. The bottom end of the clamping block 320 is fixedly connected to a slide rod 322. A spring 323 is fixedly connected between the bottom end of the clamping block 320 and the inner wall of the placement platform 310. The spring 323 is sleeved on the outer periphery of the slide rod 322. The slide rod 322 is slidably connected to the inner wall of the placement platform 310. A push rod 350 is slidably connected to the inner wall of the placement platform 310. One end of the push rod 350 is set in the groove 311, and the other end of the push rod 350 passes through the placement platform 310.

[0028] In this embodiment, the placement platform 310 consists of a ring and a rectangle. The ring is rotatably connected to the upright 100. When the culture dish needs to be placed on the support platform, the operator needs to hold the two sides of the bottom surface of the culture dish by hand and place the culture dish on the support platform through the groove. When the culture dish needs to be removed from the support platform, it also needs to be removed from the bottom surface of the culture dish through the two grooves. The support platform is connected to the slide plate 340 through a rectangular block. The placement platform 310 is provided with a rectangular groove to cooperate with the sliding of the rectangular block. The bottom surface of the support platform and the surface of the placement platform 310 are at the same level. The slide plate 340 is provided with sliding strips on both sides. The two sliding strips are also slidably connected to the inner wall of the placement platform 310. At the same time, a square block is provided at the end of the sliding strip. The square block cannot slide out of the placement platform 310 to prevent the slide plate 340 from detaching from the placement platform 310.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a baffle plate 312 is fixedly connected to the bottom end of the clamping block 320. The baffle plate 312 is slidably connected to the inner wall of the placement platform 310. The baffle plate 312 is located above the slide rod 322. A handle 200 is fixedly connected between the support base 110 and the top end of the slide rod 322. The distance from the handle 200 to the slide rod 322 is less than the length of the placement platform 310. Because the bottom end of the arc-shaped block 321 needs to be slidably connected to the placement platform 310, an opening needs to be provided on the placement platform 310. To prevent the opening from being exposed to the air for a long time and to prevent the accumulation of pollutants, and for the overall aesthetics of the device, the baffle plate 312 is required.

[0030] When using this utility model, the fixing frame is placed stably on the experimental table, and then the push rod 350 is pushed. The push rod 350 pushes the slide plate 340, so that the slide plate 340 slides out in the slide groove 311, and at the same time drives the support seat 330 to slide until the slide plate 340 drives the support seat 330 to slide completely out of the clamp 320, and then the culture dish can be placed on the support seat 330.

[0031] During this process, when the slide plate 340 drives the support seat 330 to slide outward, because the diameter of the support seat 330 is greater than the minimum distance between the two arc blocks 321, the edge of the support seat 330 will slide along the arc surface of the arc block 321, thereby pushing the two clamping blocks 320 to move to both sides, so that the support seat 330 can be completely moved out of the clamping blocks 320.

[0032] After placing the petri dish on the support 330, it needs to be fixed on the mounting bracket. At this time, the sliding plate 340 needs to be pushed so that the support 330 slides into the clamping block 320. Similarly, the support 330 will squeeze the two clamping blocks 320, so that the bottom ends of the two clamping blocks 320 slide within the placement platform 310. At the same time, it will drive the sliding rod 322 to slide away from the clamping block 320 and compress the spring 323. When the diameter of the support 330 passes through the shortest distance of the arc block 321, the elastic force released by the spring 323 will squeeze the arc block 321. The arc surface of the arc block 321 will squeeze the support 330 into the middle of the two clamping blocks 320 and restrict it in that position, thus fixing the petri dish.

[0033] Once the petri dishes are fixed in place, rotate the placement platform 310 so that multiple placement platforms 310 are staggered to prevent the petri dishes from being stacked.

[0034] When you need to remove the petri dish, simply repeat step one.

[0035] It should be noted that the spring 323 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and will not be elaborated here.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
