Description

Technical Field

[0001] The utility model relates to the technical field of transparent covers, and more particularly to a transparent cover for experiments. Background Art

[0002] A space laboratory, also known as a space lab, is a reusable, multi-purpose space station for manned space science experiments. It is a laboratory used to conduct various space science experiments. The construction process involves first launching an unmanned space lab, then using a carrier rocket to send a manned spacecraft into space. The spacecraft then rendezvouses and docks with the orbiting space lab. Astronauts then enter the space lab from the attached stage of the spacecraft to begin their work.

[0003] The space station has experimental cabinets filled with experimental supplies. Astronauts need to open drawers to retrieve items during experiments. In the weightless environment, these items float, making it difficult to perform experiments. To address this, we provide a transparent cover specifically for the experimental cabinets. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a transparent cover for experiments, which can confine the supplies in the experiment cabinet to a certain area, making it convenient for astronauts to conduct scientific experiments in the space station.

[0005] The technical solutions adopted by the present invention to solve the above technical problems are as follows:

[0006] The transparent cover for experiments includes a bag body with three-side sealing formed by two sides, an upper layer, a lower layer and a bottom, and a soft glove. The top is the bag opening. The bag body is transparent. The soft glove is fixed to the side of the bag body through the cuff. The soft glove is located inside the bag body, and the interior of the soft glove is connected to the outside of the bag through the cuff.

[0007] Preferably, the soft gloves are composed of a left and a right glove in pairs.

[0008] Preferably, the opening of the soft glove is located on the side of the bag body close to the upper layer.

[0009] Preferably, an elastic rubber band is provided at the bag opening for tightening the bag opening.

[0010] Preferably, an annular cavity is provided at the bag opening, and a pair of through holes communicating with the annular cavity are opened on the bag opening. The elastic rubber band is inserted into the annular cavity, and part of the elastic rubber band passes through the pair of through holes and is located outside the annular cavity.

[0011] Preferably, a hard sheet is provided at the bag opening.

[0012] Preferably, the hard sheet is located at the four corners of the bag opening where the two sides meet the upper layer and the lower layer.

[0013] Preferably, buckles are respectively provided at the four corners of the bag opening where the two side portions meet the upper layer and the lower layer.

[0014] Preferably, both sides of the bag body are connected and equipped with an air inlet bag and an air outlet bag respectively.

[0015] Preferably, the air inlet bag is close to the upper layer of the bag body, and the air outlet bag is close to the lower layer of the bag body.

[0016] The beneficial effects that can be achieved by the above technical solutions of the present invention are:

[0017] 1. By putting the bag on the drawer of the experimental cabinet under the fixing effect of the buckle, the drawer of the experimental cabinet is tightly wrapped in the bag, effectively preventing the experimental supplies from floating around in a weightless environment, thereby ensuring the smooth progress of astronaut experiments;

[0018] 2. By setting air inlet bags and air outlet bags on both sides of the bag, the air inside the bag can be effectively kept clean, thus ensuring the experimental effect;

[0019] 3. By placing pairs of soft gloves inside the transparent bag, astronauts can conduct experimental operations under visual conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Depend on Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the transparent cover for experiment includes a bag body 5 with three-side sealing consisting of two side parts 1, an upper layer 2, a lower layer 3 and a bottom 4, and a soft glove 6. The top is a bag opening 7. The bag body 5 is transparent, which is convenient for astronauts to clearly see the experimental supplies and experimental conditions in the bag body 5 when conducting experiments. The inner cavity of the bag body 5 matches the shape of the drawer of the experimental cabinet. The soft glove 6 is fixed on the side 1 of the bag body 5 through the sleeve 8. The soft glove 6 is located in the bag body 5. The interior of the soft glove 6 is connected to the outside of the bag body 5 through the sleeve 8. In order to facilitate experimental operations, the soft glove 6 is composed of left and right gloves in pairs. When conducting experimental operations, the astronaut's left and right hands are respectively extended into the bag body 5 from the left and right openings 8. Since the experimental operation supplies are located in the drawer of the experimental cabinet, the opening of the soft glove 6 is located on the side 1 of the bag body 5 near the upper layer 2, which can effectively avoid the baffles on both sides of the drawer. An annular cavity is provided at the bag opening 7, and a pair of through holes 10 connected to the annular cavity are opened on the bag opening 7. An elastic rubber band 9 is inserted into the annular cavity, and part of the elastic rubber band 9 passes through the pair of through holes 10 and is located outside the annular cavity. The bag opening 7 can be contracted by the elastic rubber band 9, so that the bag opening 7 can be tightened. On the drawer, a hard sheet 11 is provided at the pocket opening 7. The hard sheet 11 is located at the four pocket corners of the pocket opening 7 where the two side parts 1 meet the upper layer 2 and the lower layer 3. When multiple adjacent drawers need to be opened at the same time, and the gaps between adjacent drawers are narrow, the pocket opening 7 can be guided by the hard sheet 11 to be inserted into and fixed to the drawer of the experimental cabinet. In order to prevent the pocket opening 7 of the bag body 5 from being separated from the experimental cabinet during experimental operation, buckles 12 are respectively provided at the four pocket corners of the pocket opening 7 where the two side parts 1 meet the upper layer 2 and the lower layer 3. The buckles 12 can be hard plastic parts. It is fastened with the four corners of the drawer on the laboratory cabinet to fix the bag so that the bag opening will not slip easily when it is opened. The two side parts 1 of the bag body 5 are respectively connected to the air inlet bag 13 and the air outlet bag 14. The air inlet bag 13 is close to the upper layer 2 of the bag body 5, and the air outlet bag 14 is close to the lower layer 3 of the bag body 5. In this way, clean air enters from the air inlet bag 13 near the upper layer 2 of the bag body 5, and is discharged from the air outlet bag 14 near the lower layer 3 of the bag body 5, which is conducive to extending the travel of clean air, carrying away harmful substances produced during the experiment, and ensuring the cleanliness of the air in the drawer inside the bag body 5.

[0026] In actual use, the operator tightens the bag to the drawer of the laboratory cabinet through the elastic rubber band at the bag opening, and then connects and installs the inflation device and the exhaust device on the air inlet bag 13 and the air outlet bag 14. After installation, the operator inserts his hands into the left and right soft gloves to open the drawer containing the experimental items, and then takes out the experimental items for experiment. After completion, the drawer is reset and the bag is removed.

[0027] This product is for laboratory use only and is used for scientific experiments, biological research, hazardous substance isolation experiments, etc.
