Description

Technical Field

[0001] The utility model relates to the technical field of test tube fixing clamps, in particular to a biological tissue test tube fixing clamp used for an immune labeling instrument. Background Art

[0002] Immunolabeling technology refers to the use of fluorescein, radioisotopes, enzymes, ferritin, colloidal gold and chemiluminescent (or bioluminescent) agents as tracers to label antibodies or antigens for antigen-antibody reactions, with the aid of instruments such as fluorescence microscopes and enzyme label detectors. For example, the patent document with application number CN201810090214.0 discloses a test tube holder, which can change the distance between the support plate and the fixing plate by inserting the support plate and the fixing plate in different slots, so as to adapt to test tubes of different specifications, thereby improving the applicability of the device.

[0003] However, in the above-mentioned similar schemes, due to the small internal space of the instrument, the test tubes are arranged relatively densely. When a single test tube needs to be taken out, all the test tubes around it need to be taken out, which wastes time and is not convenient for quick retrieval. Moreover, when all the test tubes are taken out, they need to be taken out together with the base below, which is blocked by the base, resulting in that the color of the liquid in the test tube cannot be directly observed after taking it out.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a biological tissue test tube fixing clamp for an immunolabeling instrument is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a biological tissue test tube fixing clamp for an immunolabeling instrument, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. Since the internal space of the instrument is small, the test tubes are arranged relatively densely. When a single test tube needs to be taken out, all the surrounding test tubes need to be taken out, which wastes time and is inconvenient to take out quickly. Moreover, when all the test tubes are taken out, they need to be taken out together with the base below, which is blocked by the base, resulting in the problem that the color of the liquid in the test tube cannot be intuitively observed after taking them out.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a biological tissue test tube fixing fixture for an immunolabeling instrument, comprising a base, a rotating assembly and a fixed assembly, the rotating assembly is located above the base, and the rotating assembly comprises a rotating disk, a supporting roller, a test tube slot and a second magnet, and the upper end of the base is slidably connected to the supporting roller, the upper end of the supporting roller is fixed with the rotating disk, and the inner side of the supporting roller is surrounded by a plurality of groups of the test tube slots, and the bottoms of the plurality of groups of the test tube slots are slidably connected to the second magnet, the fixed assembly is located at the upper end of the rotating assembly, and the fixed assembly comprises a fixed disk, an electric telescopic rod and a clamping block, the upper end of the rotating disk is clamped with the fixed disk, and the lower end of the fixed disk is surrounded by a plurality of groups of the electric telescopic rods, and the outer sides of the plurality of groups of the electric telescopic rods are fixed with the clamping blocks.

[0007] Furthermore, a marking device is provided on the outer side of the fixed component, and the fixed component is engaged with the rotating component to form a disassembly structure.

[0008] Furthermore, a column is fixed at the center of the upper end of the base, and a bearing is interference-connected on the outer side of the column, and the rotating disk forms a rotating structure with the base through the supporting roller and the bearing.

[0009] Furthermore, the test tube slots and the second magnets are each provided in ten groups, and the upper ends of the ten groups of the second magnets are connected with rubber sleeves.

[0010] Furthermore, a baffle is engaged with the outer side of the column, and a first magnet is arranged below the baffle, and the electrodes of the first magnet and the second magnet on a side close to each other are of the same pole.

[0011] Furthermore, a limiting protrusion is fixed below the supporting roller, a magnet slot is fixed at the bottom of the test tube slot, and a limiting slot is provided through the upper end of the rotating disk.

[0012] The utility model provides a biological tissue test tube fixing fixture for an immune labeling instrument, which has the following beneficial effects:

[0013] When the test tubes are densely arranged, it is not necessary to take out all the surrounding test tubes when taking out a single test tube, which can save time and facilitate accurate and fast taking. Moreover, when all the test tubes are taken out, it is possible to avoid taking out the base below together to avoid being blocked by the base, so that the color of the liquid in the test tube can be directly observed after taking it out. The specific contents are as follows:

[0014] The user rotates the rotating disk and the supporting roller to make the test tubes in different positions pass over the first magnet. Since the two groups of magnets with the same poles repel each other, the second magnet drives the test tube to bulge upward, so that the labels on the test tubes leak out, making it easier for the user to take them out. When all the test tubes are taken out, the electric telescopic rod drives the clamping block to fit the test tubes. The test tubes are subjected to the pressure between the fixed disk and the electric telescopic rod, which can prevent the test tubes from falling. The fixed disk can be lifted to take out all the test tubes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, a biological tissue test tube fixing fixture for an immunolabeling instrument comprises a base 2, a rotating assembly 3 and a fixing assembly 5, wherein a marking instrument 1 is arranged on the outer side of the fixing assembly 5, and the changes in the test tube are detected by placing the test tube into the marking instrument 1, the rotating assembly 3 is located above the base 2, and a column 21 is fixed at the center of the upper end of the base 2 for supporting and fixing a bearing 4, and the outer side of the column 21 is interference-connected with a bearing 4 for connecting a support roller 302 and the base 2, so that a rotating disk 301 forms a rotating structure with the base 2 through the support roller 302 and the bearing 4, so that when the rotating assembly 3 is rotated, the base 2 can be fixed, and the rotating assembly 3 comprises a rotating disk 301, a support roller 302, a test tube slot 303 and a second magnet 304, and the upper end of the base 2 is slidably connected with the support roller 302, and a limiting protrusion 321 is fixed below the support roller 302, and the rotating assembly 3 is rotated along the edge of the base 2 by the limiting protrusion 321, thereby improving the rotation stability of the rotating roller 302;

[0022] A rotating disk 301 is fixed to the upper end of the support roller 302, and the rotating disk 301 is set to highlight the marking instrument 1, which is convenient for users to use and adjust, and a plurality of test tube grooves 303 are arranged around the inner side of the support roller 302 to place test tubes to prevent the test tubes from tipping over during use and causing reagent contamination, and a magnet groove 331 is fixed to the bottom of the test tube groove 303 to guide the rising and falling directions of the second magnet 304, and the second magnet 304 is slidably connected to the bottom of the plurality of test tube grooves 303. Because the first magnet 23 is arranged below the baffle 22, and because the electrodes on the side where the first magnet 23 and the second magnet 304 are close to each other are of the same pole, when the second magnet When 304 moves to the top of the first magnet 23, the second magnet 304 moves upward due to the principle of magnets with the same poles repelling each other, thereby driving the test tube on the upper end of the magnet to bulge upward, causing the label to leak out. When taking out a single test tube, time can be saved, which is conducive to accurate and fast taking. The test tube slots 303 and the second magnets 304 are each provided with ten groups, and the upper ends of the ten groups of second magnets 304 are connected with rubber sleeves 341 for protecting the test tubes, which can reduce the damage when the test tubes collide with the second magnets 304. The outer side of the column 21 is engaged with a baffle 22, so that the second magnet 304 can rotate on the baffle 22, so that the second magnet 304 can rotate smoothly on the base 2.

[0023] The fixing assembly 5 is located at the upper end of the rotating assembly 3, and the fixing assembly 5 includes a fixing disk 501, an electric telescopic rod 502 and a clamping block 503. The upper end of the rotating disk 301 is clamped with the fixing disk 501. Because the upper end of the rotating disk 301 is penetrated by a limiting groove 6, the fixing assembly 5 forms a disassembly structure with the rotating assembly 3 through clamping. The fixing disk 501 is plugged into the inner side of the limiting groove 6, so that the fixing disk 501 can be quickly removed from the rotating disk 301 through elastic deformation, thereby facilitating the rapid separation of the test tube and the rotating assembly 3. The lower end of the fixing disk 501 is surrounded by a plurality of groups of electric telescopic rods 502, and the outer sides of the plurality of groups of electric telescopic rods 502 are fixed with clamping blocks 503. The clamping blocks 503 are arc-shaped surfaces that fit the outer wall of the test tube. The test tube is clamped by the electric telescopic rod 502, thereby improving the clamping stability, so that the test tube can be taken out without the support of the base 2, thereby avoiding the base from being blocked, so that the color of the liquid in the test tube can be directly observed after it is taken out.

[0024] In summary, when the biological tissue test tube fixing fixture for the immunolabeling instrument is used, first, the test tube is inserted into the test tube slot 303, at which time the bottom of the test tube contacts the second magnet 304. When the user takes out a single test tube after the test, the user rotates the rotating disk 301 to drive the support roller 302 and the bearing 4 to rotate. At the same time, the second magnet 304 slides along the upper end surface of the baffle 22, and the fixed protrusion 321 slides along the edge of the base 2, so that the second magnets 304 at different positions pass over the first magnet 23. Since the two groups of magnets have the same poles that repel each other, the second magnet 304 moves upward along the magnet slot 331 and drives the test tube to bulge upward, so that the label on the test tube leaks out, which is convenient for users to select. When all the test tubes are taken out, several groups of electric telescopic rods 502 extend outward at the same time, thereby driving the clamping block 503 to fit the outer wall of the test tube. The test tube is clamped by the pressure between the fixed plate 501 and the electric telescopic rod 502, and then the fixed plate 501 is lifted upward to separate the bottom of the fixed plate 501 from the limiting slot 6, so that all the test tubes are taken out.
