Description

TECHNICAL FIELD

[0001] The utility model belongs to cell test tube classification and placement technical field, concretely relates to cell classification and isolation frame. BACKGROUND

[0002] When sampling cells, the sampling swab is stored in a sampling tube containing cell preservative after sampling, and the sampling tube is usually placed on an isolation frame for waiting for use during experiments. A limiting hole is usually formed on the isolation frame to clamp the sampling tube. However, when the sampling tube has multiple sizes, it cannot be placed on the same isolation frame, resulting in increased experimental cost.

[0003] Patent CN202420819568.5 discloses a cell culture test tube placement tray. The sampling tube is placed in a containing hole (i.e. limiting hole) on the tray (i.e. isolation frame), and then clamped by a clamping device, so as to be suitable for sampling tubes with different sizes. However, the above-mentioned scheme still has the following technical problems: when the size of the sampling tube and the size of the limiting hole are quite different, i.e. the outer diameter of the sampling tube is much smaller than the inner diameter of the limiting hole, the limiting hole cannot effectively limit the sampling tube, and the sampling tube will be tilted when placed in the limiting hole. Before the clamping device clamps the sampling tube, the operator needs to manually hold the sampling tube to make it located at the center of the limiting hole, so as to avoid the problem that the sampling tube cannot be clamped by the clamping device due to tilting, and even cause the solution in the sampling tube to flow out. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a cell classification and isolation frame to solve the problem that when the size of the sampling tube and the size of the limiting hole are quite different, i.e. the outer diameter of the sampling tube is much smaller than the inner diameter of the limiting hole, the limiting hole cannot effectively limit the sampling tube, and the sampling tube will be tilted when placed in the limiting hole. Before the clamping device clamps the sampling tube, the operator needs to manually hold the sampling tube to make it located at the center of the limiting hole, so as to avoid the problem that the sampling tube cannot be clamped by the clamping device due to tilting, and even cause the solution in the sampling tube to flow out.

[0005] According to the embodiments of the utility model, the following technical scheme is adopted:

[0006] The cell classification and isolation frame comprises a frame body, a plurality of limiting plates fixed on the frame body in the vertical direction, a plurality of limiting holes distributed along the length direction of the limiting plates, and a supporting plate arranged at the bottom of the frame body. The inner diameter of the limiting hole on the limiting plate decreases from top to bottom along the frame body, and the corresponding plurality of limiting holes are coaxially arranged in the vertical direction. A plurality of limiting assemblies corresponding to the limiting holes are arranged on the limiting plate. Each limiting assembly comprises two clamping blocks arranged on both sides of the limiting hole, and the clamping blocks are slidingly connected to the limiting plate. A plurality of grooves corresponding to the limiting holes are arranged on the supporting plate.

[0007] Compared with the prior art, the utility model has the beneficial effects that:

[0008] In the scheme, through setting multilayer limit board, the limit hole inner diameter of multilayer limit board along vertical direction is sequentially reduced along from top to bottom direction, then sampling tube can be inserted into limit hole with little size difference, and limit effect is received, and it is avoided that sampling tube is too large in dumping angle. Then the sampling tube is clamped by the clamping block, and the clamping block on the multilayer limit board can clamp the sampling tube in multiple places along the vertical direction, so that the sampling tube maintains a stable vertical state.

[0009] Further, the limit hole upper side is equipped with the guide portion in inverted cone shape.

[0010] Further, the multiple clamping blocks corresponding along the vertical direction are commonly connected with the connecting plate, and further comprising a driving member for driving the connecting plate to move.

[0011] Further, the driving member comprises a driving rod, the two sides of the driving rod are respectively screw-connected with the two connecting plates located on the two sides of the limit hole, and the screw rotation directions of the two sides of the driving rod are opposite.

[0012] Further, the end of the driving rod is fixed with a handle.

[0013] Further, the opposite side of the clamping block on the two sides of the limit hole is fixed with a first flexible pad.

[0014] Further, the inner wall of the limit hole is fixed with a second flexible pad.

[0015] Further, the bottom of the supporting plate is equipped with a suction disc. BRIEF DESCRIPTION OF DRAWINGS

[0019] The utility model will be further explained in detail below in combination with the drawing of the specification, and specific implementation mode is given.

[0020] For example Figure 1 , Figure 2As shown, the cell classification isolation frame comprises a frame body 1, a plurality of limiting plates 4 fixed vertically on the frame body 1, a plurality of limiting holes 5 distributed along the length direction of the limiting plates 4, and a supporting plate 2 arranged at the bottom of the frame body 1, which is used to be placed on the desktop or countertop.

[0021] The inner diameter of the limiting hole 5 on the limiting plate 4 decreases from top to bottom along the frame body 1, and a plurality of limiting holes 5 are coaxially arranged vertically. In this way, the sampling tube with different outer diameters can be inserted into the limiting hole 5 with similar size when inserted into the multi-layer limiting plate 4, and the limiting effect is achieved. Even if the limiting hole 5 cannot completely hold the sampling tube, the sampling tube will not tilt at a large angle, avoiding the solution in the sampling tube from flowing out. In order to avoid the sampling tube from colliding with the inner wall of the limiting hole 5 when shaking in the limiting hole 5, a second flexible pad is fixed on the inner wall of the limiting hole 5. Specifically, the second flexible pad can be a rubber gasket in the prior art.

[0022] The upper side of the limiting hole 5 is provided with a reverse tapered guide part 6. When the outer diameter of the sampling tube cannot completely pass through all the limiting holes 5 on the limiting plate 4, the lower end of the sampling tube will be stuck in the limiting hole 5 on one of the limiting plates 4 and cannot be inserted further. At this time, the guide part 6 can also limit the bottom of the sampling tube to a certain extent. The supporting plate 2 is provided with a plurality of grooves 3 corresponding to the limiting holes 5. When the sampling tube passes through all the limiting holes 5 on the limiting plate 4 and abuts against the supporting plate 2, the groove 3 limits the bottom of the sampling tube to a certain extent.

[0023] The limiting plate 4 is also provided with a plurality of limiting assemblies corresponding to the limiting holes 5 one by one. The limiting assembly comprises two clamping blocks 7 arranged on both sides of the limiting hole 5, respectively. The clamping blocks 7 are slidingly connected to the limiting plate 4. By sliding the two clamping blocks 7 towards each other to clamp the sampling tube on both sides, the sampling tube is clamped and limited. In order to avoid the clamping force being too large to damage the sampling tube, the opposite side of the clamping block 7 on both sides of the limiting hole 5 is fixed with a first flexible pad. Specifically, the first flexible pad can be made of a sponge block in the prior art, which protects the sampling tube through the buffering of the first flexible pad.

[0024] In combination Figure 2As shown, the corresponding plurality of clamping blocks 7 in the vertical direction are jointly connected with a connecting plate 8, specifically, the clamping blocks 7 are each fixed with a connecting rod, and the plurality of connecting rods are fixed on the connecting plate 8, that is, the corresponding plurality of clamping blocks 7 in the vertical direction can be simultaneously driven to move through the connecting plate 8, in the embodiment, a driving member for driving the connecting plate 8 to move is further included, specifically, the driving member includes a driving rod 9, the two sides of the driving rod 9 are respectively and threadedly connected with the two connecting plates 8 located on the two sides of the limiting hole 5, and the threads on the two sides of the driving rod 9 are opposite in rotation direction, by rotating the driving rod 9, the two connecting plates 8 located on the two sides of the driving rod 9 can be controlled to move towards each other or away from each other. A handle 10 is fixed at the end of the driving rod 9, so as to facilitate the staff to rotate the driving rod 9 through the handle 10.

[0025] The bottom of the supporting plate 2 is provided with a suction cup 11, which can be a conventional rubber suction cup 11, to increase the stability of the supporting plate 2 placed on the desktop, so as to avoid the instability of the frame body 1 caused by the unilateral arrangement of the limiting assembly.

[0026] Specifically in use, the sampling tube can be inserted downward into the limiting hole 5 with a size difference, after being limited, the driving rod 9 is rotated, the two connecting plates 8 located on the two sides of the driving rod 9 are controlled to move towards each other, the connecting plate 8 drives the clamping block 7 to move to clamp the sampling tube, and the clamping blocks 7 on the plurality of limiting plates 4 can clamp the sampling tube at multiple places in the vertical direction, so that the sampling tube is kept in a stable vertical state.
