Description

A stackable and adjustable petri dish rack

technical field

The utility model relates to the technical field of laboratory supplies, in particular to a stackable and adjustable petri dish rack.

Background technique

Petri dishes are laboratory vessels widely used in cell culture, bacterial culture, small plant culture, storage of samples, and chemical experiments. The common diameters are 35, 55, 60, 70, 90, and 150mm. A dish-shaped bottom and a cover, usually made of glass or plastic. Glass petri dishes are reusable, and plastic petri dishes are generally disposable, but there are also plastic petri dishes that can be reused.

Laboratories generally need to take up a lot of space to store petri dishes. In addition, the petri dishes are frequently used and need to be washed and dried frequently. It may take up a lot of laboratory benches to dry. At present, when the petri dishes are not stored and dried in the laboratory A certain number of petri dish covers or dish bottoms are damaged (especially glass petri dishes), which reduces the use efficiency of the petri dishes and increases the expenditure on experimental consumables, thus affecting the experimental process.

Contents of the invention

The technical problem solved by the utility model is to provide a superimposed and adjustable culture dish rack. The device can store and dry different types of culture dishes through its structural design, and can also store the dish cover and the bottom of the dish separately according to needs. Reduce or avoid losses caused by collisions.

The technical solution of the utility model is: a superimposed and adjustable culture dish rack, including support legs and grooves, characterized in that: the grooves are composed of one or more than one groove, and each groove has a drainage hole at the lower end .

The drain hole described in the utility model is connected with a horizontal drain groove.

The inner surface of the groove described in the utility model is a smooth slope, and the connection between the groove and the drainage groove is a telescopic structure.

The utility model includes four supporting legs, and the upper end of each supporting leg is provided with an insertion groove, and the second layer of culture dish rack can be inserted into the insertion groove of the first layer of culture dish rack through the supporting legs.

The working principle of the utility model is: a superimposed and adjustable culture dish rack, including support legs and grooves, the grooves are composed of one or more grooves, and each groove has a drainage hole at the lower end. The drainage hole is connected to a horizontal drainage groove, and the drainage groove (surface) is inclined to one end, so that the accumulated water can be discharged from the main drainage hole; the bottom of the groove is equipped with a foldable structure for adjusting the size of the groove, which can meet the needs of different sizes of cultivation It includes four supporting legs, and the upper end of the supporting legs is provided with an insertion slot, and the second layer of culture dish rack can be inserted into the insertion slot of the first layer of culture dish rack through the insertion legs, so that the culture dish rack can be superimposed on two layer or more.

The new beneficial effects of the utility model are: the utility model is simple and reasonable in structure, occupies a small space, and is more practical; the bottom of the petri dish and the lid of the petri dish are stored separately to avoid mutual collision and damage; the petri dish racks can be stacked to save space; The utility model can be used for storing or carrying the culture dish, and can be used for drying the culture dish, and is suitable for popularization and application.

Detailed ways

Below in conjunction with accompanying drawing, present embodiment is described further:

 A superimposed and adjustable petri dish rack, including line-type adjustable grooves 1 arranged obliquely, four support columns 6, the upper end of the support columns is provided with an insertion groove 7, the lower end is an insertion column 8, and a drainage groove 3 , the total drainage hole 4.

The groove 1 includes one or more grooves arranged in parallel. The number of grooves can be adjusted according to the needs. Generally, more than ten are better. The bottom surface of the linear groove is arc-shaped, and the lowest part is connected to a drainage hole. 2. Allow the accumulated water on the cleaned culture dish to flow to the drainage groove 3 below the groove, and finally drain through the main drainage hole 4.

Further, in order to store culture dishes of different sizes, the size of the groove can be designed according to the size of the design, and a foldable structure can also be designed at the bottom of the line groove. It can be folded up, as shown in Figure (51), and it can be stretched out for use when placed in a large petri dish (generally >6cm in diameter), as shown in Figure (52). At the same time, the structure can be used as a baffle, which can prevent the bottom or cover of the culture dish from rolling left and right, and is convenient to take.

Further, the upper part of the groove 1 is inclined towards the rear or front of the petri dish rack as a whole, so that the bottom of the petri dish or the lid of the petri dish can be inclined to one side when placed, so as to facilitate the outflow of accumulated water and reduce the time required for drying.

Further, the two grooves 1 arranged in parallel can store the bottom of the petri dish in one row, and the lid of the petri dish in the other row, which is convenient for taking and matching; it can also store the bottom of the petri dish or the lid of the petri dish uniformly, which is convenient for classification and storage. To reduce damage to one of the bottom or lid of the petri dish during use, which is often discarded because it cannot be placed in a matching manner, so that it can be stored in a centralized manner in the laboratory, and can be used as a cross-matching set after accumulation to a certain extent.

There are four support columns 6, each support column upper end is provided with a plug-in slot 7, and the lower end is a plug-in column 8, and the second layer of petri dish rack can be inserted into the slot of the first layer of petri dish rack through the plug-in post inside, so that the petri dish racks can be stacked in two or more tiers.

Further, in order to ensure that there is no contact and collision between layers of the petri dish rack, the height of the plug-in column should be optimized during design, so that when the petri dish racks are stacked, the bottom of the upper rack is higher than the bottom of the lower petri dish or the upper end of the lid.

Further, in order to avoid tilting or shaking of the petri dish rack when the number of stacked layers increases, an auxiliary device can be erected on the bottom petri dish if necessary, such as a fixture that can be fixed to the ground, desktop or wall.

The lower end of the insertion column 8 is tapered, and the end is truncated and blunt, which is convenient for the stable placement of the petri dish and avoids scratching the operator when it is too sharp.

The drainage groove 3 is located at the lower end of the above-mentioned groove 1, and the top communicates with the drainage hole 2 of the groove. In order to facilitate the drainage groove to discharge accumulated water, one end of the drainage groove can be installed higher than the other end during design, or the surface of the drainage groove can be designed as Inclined.

Described total drain hole 4 is the lowest end of drain groove, and the effect of total drain hole is: after cleaning culture dish, need to dry and remain at the bottom of culture dish dish or the water on the dish lid gathers and can discharge through drain hole. In order to prevent the upper layer of water from dripping onto the lower layer of the petri dish rack, the drain hole is designed to protrude a certain distance from the groove.

Further, in order to prevent the discharged water from flowing to the test bench or the ground during drying and use, if necessary, a water storage (bottle) can be connected to the rear end of the main drainage hole 4 during design, or a water pipe can be connected to the drainage pool. It can be removed when dry for storage.
