Description

Test-tube rack for refrigerator storage test-tubes

Technical Field

The utility model relates to a test tube rack, in particular to a test tube rack for storing test tubes or test tube bottles in a refrigerator.

Background

Chemical reagents and solutions often need to be refrigerated or frozen in a refrigerator to avoid too rapid degradation or evaporation. However, there are many problems in this field. Because the containers of various reagents and solutions have large diameter and height difference, the containers are placed in test tube racks with different specifications, and the sizes and the shapes of each layer of the refrigerator are also different, so that the containers are disorderly in the refrigerator with very limited space, the space utilization rate is low, and the containers are very difficult to find. In the long-time searching process, the refrigerator exchanges heat with the outside to cause frosting or icing, and the refrigerator door can not be closed seriously. The unreasonable use of refrigerator space undoubtedly increases the number of refrigerators, and the heat exchange during searching can cause great energy waste.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a refrigerator storage test tube rack which makes full use of the space of a refrigerator, is easy to find and reduces frosting and icing.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a refrigerator stores test-tube rack that test-tube was used, includes horizontal perforated plate and is located horizontal perforated plate below the collet, horizontal perforated plate's upper surface bilateral symmetry be provided with the handle, the bottom of handle be provided with the screw thread post, the screw thread post on be provided with the nut, the screw thread post pass horizontal perforated plate with nut swing joint, the bottom of screw thread post with collet fixed connection, horizontal perforated plate separate for a plurality of module region, the module region in be provided with the round hole of aperture size homogeneous, any module region in each round hole evenly distributed and adjacent two rows of round holes between cross arrangement.

The collet on be provided with the constant head tank that is used for supporting the test tube bottom, the aperture of constant head tank do the porous plate of level on 1/5 ~ 1/3 in round hole aperture.

The bottom of the threaded column is fixedly connected with the bottom support in a bolt mode.

And a hollow area which is communicated up and down is arranged in the middle of the horizontal porous plate.

The hollow area is provided with a movable pore plate for placing test tubes with different apertures.

The inner wall of the hollow area is provided with a supporting block for supporting the movable orifice plate, and the movable orifice plate is just clamped in the hollow area and is positioned on the supporting block.

The round holes on the movable orifice plate are uniformly distributed and are arranged in a crossed manner between two adjacent rows of round holes.

The round holes on the horizontal porous plate are provided with numbers or coordinate marks.

The size of the test tube rack is matched with the space size of one layer of the refrigerating chamber of the refrigerator.

Compared with the prior art, the utility model has the advantages that:

1. the refrigerator has the advantages that the refrigerator is arranged one by one, the whole refrigerator can be conveniently placed in or taken out, and the space is fully utilized.

2. The cross arrangement between two adjacent rows of holes does not influence under the prerequisite that test tube or test tube bottle placed, and level and side interval accomplish the minimum, compares ordinary side by side and arranges, promotes space utilization by a wide margin.

3. And the numbers or the coordinates are marked, so that the search is convenient.

4. Through the height of adjusting the nut on the handle cylinder, can change the height of horizontal perforated plate apart from the collet, adapt to not the test tube or the test tube bottle of co-altitude.

5. Besides the common same aperture, the perforated plate also has a movable modular structure, so that test tube racks with different apertures can be freely combined conveniently. The movable hole plate can be taken out to become an object placing area, so that other test tubes (bottles) with unusual diameters and other plastic packages and the like can be conveniently placed.

6. The test tube racks are designed according to the size of the refrigerating chamber of the refrigerator, and the test tube racks occupy one layer of space as much as possible according to the principle that the test tube racks are arranged one by one, so that the test tube racks can be freely placed in or taken out.

Drawings

Fig. 1 is a first structural schematic diagram of a test tube rack for storing test tubes in a refrigerator according to the present invention.

Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Example 1

The utility model provides a refrigerator stores test-tube rack that test-tube was used, as shown in figure 1, including horizontal perforated plate 1 and the collet 2 that is located horizontal perforated plate 1 below, through 3 body couplings of handle between horizontal perforated plate 1 and the collet 2, the upper surface bilateral symmetry of horizontal perforated plate 1 is provided with handle 3, the bottom of handle 3 is provided with screw thread post 4, be provided with nut 5 on the screw thread post 4, screw thread post 4 passes horizontal perforated

plate

1 and 5 swing joint of nut, the bottom and the collet 2 fixed connection of screw thread post 4, horizontal perforated plate 1 separates for a plurality of module region 6, be provided with the round hole 7 of aperture size homogeneous in the module region 6, cross arrangement between 7 evenly distributed of each round hole 7 and two adjacent rows of round holes 7 in any module region 6.

In this embodiment, the bottom support 2 is provided with a positioning groove 8 for supporting the bottom of the test tube, and the aperture of the positioning groove 8 is 1/5-1/3 of the aperture of the round hole on the horizontal porous plate 1. The bottom of the threaded column 4 is fixedly connected with the bottom support 2 in a bolt mode.
