Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-low temperature refrigerators, and in particular relates to an ultra-low temperature refrigerator for placing biological samples in different categories. Background Art

[0002] Biological samples usually refer to flowers, leaves, stems, roots, seeds, etc. of plants, body fluids, hair, muscles and some tissues and organs of animals (including humans) and various microorganisms. After the microorganisms are collected, they are placed in a preservation tube, and the preservation tube for collecting biological samples is frozen, usually by an ultra-low temperature refrigerator. The existing ultra-low temperature refrigerator is a device used for preserving and freezing biological samples. The ultra-low temperature refrigerator is convenient for classifying and placing different types of biological sample preservation tubes during freezing. After classification and placement, they are clamped and fixed, and the placement is more stable, which improves the stability of the ultra-low temperature refrigerator for classifying and placing sample preservation tubes of different sizes;

[0003] When the existing ultra-low temperature refrigerator classifies and stores biological samples, the biological samples are stored in storage tubes. When the sample storage tubes are classified and placed, they are directly placed in the placement grooves.

[0028] A classification placement component is arranged inside the sample placement rack 103, and a clamping component is arranged inside the classification placement component. An air intake component is arranged on the top of the clamping component. When the ultra-low temperature refrigerator body 100 stores samples, the classification placement component can classify and place the sample storage tubes. After placement, the clamping component can clamp the sample storage tubes of different sizes again, making the placement more stable, thereby improving the stability of the classification placement of the sample storage tubes of different sizes by the ultra-low temperature refrigerator body 100.

[0029] In order to facilitate the classified placement of different sample preservation tubes through the classified placement component and make the placement more convenient, in the present embodiment, preferably, the classified placement component includes a classified placement hole 1032 opened inside the sample placement rack 103, and a breathable mesh plate 1037 is provided at the inner bottom end of the classified placement hole 1032. The sample preservation tubes are classified and placed inside the classified placement hole 1032, and the interior of the classified placement hole 1032 is frozen through the breathable mesh plate 1037 when frozen after placement.

After the airbag body 1033 is fixed, sample preservation tubes of different sizes are clamped and placed inside the classification placement hole 1032, which is easy to fasten and install, and the placement is more stable.

[0031] In order to facilitate inflation of the interior of the airbag body 1033 through the air intake assembly, in the present embodiment, preferably, the air intake assembly includes a threaded air inlet 1036 disposed at the top of the airbag body 1033, and a sealing cover 1035 is rotatably connected to the top of the threaded air inlet 1036, and air is inflated into the interior of the airbag body 1033 through the threaded air inlet 1036 and is sealed and fixed by the sealing cover 1035.

[0032] Cleaning components are arranged on both sides of the heat dissipation net 105, and sliding components are arranged at the ends of the cleaning components. The ultra-low temperature refrigerator body 100 can dissipate heat through the heat dissipation net 105 when in use. When dust falls on the surface of the heat dissipation net 105 exposed to the outside world, the sliding components drive the cleaning components to slide and clean on the surface of the heat dissipation net 105, which is convenient for cleaning and improves the convenience and heat dissipation effect of cleaning the heat dissipation net 105 of the ultra-low temperature refrigerator body 100 when classifying and storing samples.

[0033] In order to facilitate the sliding cleaning of the surface of the heat dissipation net 105 through the cleaning component, facilitate the cleaning process, and effectively dissipate heat from the heat dissipation net 105, in the present embodiment, preferably, the cleaning component includes connecting plates 1051 arranged on both sides of the heat dissipation net 105, the inner surface of the connecting plate 1051 is provided with a brush 1053, and a paddle plate 1052 is provided at the middle position of the outer surface of the connecting plate 1051. The paddle plate 1052 is held by hand to drive the connecting plate 1051 and the brush 1053 to slide on the surface of the heat dissipation net 105, and it is convenient to clean the inner and outer surfaces of the heat dissipation net 105 at the same time, and cleaning is convenient.

[0034] In order to facilitate sliding adjustment of the connecting plate 1051 and the brush 1053 through the sliding component and facilitate sliding cleaning, in the present embodiment, preferably, the sliding component includes a slide groove 1055 opened at both ends of the heat dissipation net 105 and located inside the main box body 101, and the inside of the slide groove 1055 is slidably connected with a slider 1054, and the end of the slider 1054 is fixed to the end of the connecting plate 1051 by screws, and the connecting plate 1051 and the brush 1053 are slidably cleaned by sliding the slider 1054 inside the slide groove 1055.

[0035] The working principle and use process of the utility model are as follows: when using the ultra-low temperature refrigerator for biological samples that can be placed in different categories, the ultra-low temperature refrigerator body 100 can be stably placed in the use position by touching the ground with the bottom of the main box body 101. When the ultra-low temperature refrigerator body 100 is stably placed for frozen storage, the sample label is placed inside the label placement transparent box 104, and the sample storage tube is placed inside the sample placement rack 103. The sample placement rack 103 is again engaged with the inside of the main box body 101, and the box door 102 is closed to freeze the sample through the ultra-low temperature refrigerator body 100. When taking out, it is convenient to observe the label placement transparent box 104 to take out the corresponding sample;

[0036] Then, before the ultra-low temperature refrigerator body 100 places the sample preservation tube, the external threaded ring 1034 rotates inside the internal threaded groove 1031 to fix the airbag body 1033 inside the classification placement hole 1032, and the air is inflated into the airbag body 1033 again through the threaded air inlet 1036. The sealing cover 1035 is rotated to seal the threaded air inlet 1036, and the sample preservation tube is passed through the airbag body 1033 until it is embedded in the inner bottom end of the classification placement hole 1032. At this time, when placing the sample preservation tube, the airbag body 1033 is deformed to clamp the sample preservation tube inside the classification placement hole 1032. Therefore, the airbag body 1033 can be deformed to facilitate the clamping and placement of preservation tubes of different sizes, and the placement is more stable, thereby improving the stability of the ultra-low temperature refrigerator body 100 for the classification placement of sample preservation tubes of different sizes.

[0037] Finally, when the ultra-low temperature refrigerator body 100 is in operation for a long time, the heat generated at the bottom inside is dissipated through the heat dissipation net 105. The heat dissipation net 105 is exposed to the outside. When dust falls on and adheres to the surface of the heat dissipation net 105, the dial plate 1052 can be held to take the connecting plate 1051. When sliding the connecting plate 1051, the slider 1054 is driven to slide inside the slide groove 1055. At this time, it is convenient to slide the two connecting plates 1051 at the same time. The sliding of the connecting plate 1051 drives the brush 1053 to slide, which is convenient for the brush 1053 to slide and clean the inside and outside of the heat dissipation net 105 at the same time, which is convenient for regular cleaning and not easy to be blocked. The heat dissipation net 105 effectively dissipates the internal heat of the main box 101, thereby improving the convenience and heat dissipation effect of cleaning the heat dissipation net 105 when the ultra-low temperature refrigerator body 100 is classified and stored.
