DETAILED DESCRIPTION

[0027] To facilitate the placement and retrieval of items and the opening and closing of containers by staff, the basic technical concept of this utility model is to provide a container using a flexible material as the box body, with a portion of the side of the box body connected by a sealing zipper. When it is necessary to open the container, simply pulling the sealing zipper creates an opening on the side, which is convenient and quick. Furthermore, when placing or retrieving items, staff do not need to hoist the items to a high height, thus facilitating operation. The following detailed description of this utility model is provided in conjunction with embodiments.

[0028] Specific embodiments of the microenvironment protection sealing device provided by this utility model:

[0029] The microenvironment protection sealing device provided in this embodiment, when in the closed state, is as follows: Figures 1-3 As shown, its overall structure is basically a cuboid. Specifically, it includes a box (thin-walled), which comprises a top wall 1, a bottom wall 9, and four side walls 2. The top wall 1, bottom wall 9, and side walls 2 enclose a receiving cavity for containing and storing items 100. These items 100 can be cultural relics, machinery, grains, etc. The receiving cavity is equipped with a one-way valve 5, and the box has a set pressure-bearing capacity. Depending on actual needs, the box can be used in two ways: if an inert gas (e.g., nitrogen) needs to be filled into the receiving cavity, the one-way valve 5 can be used to connect a gas filling device to fill the cavity. If a vacuum is required, the one-way valve 5 can be used to connect a vacuum pump to extract the gas from the receiving cavity. The pressure-bearing capacity of the box is not specifically limited here; those skilled in the art can calculate it based on the size of the box.

[0030] The enclosure is made of a flexible material, specifically TPU or PVC, both of which are readily available products from the market. However, in other embodiments, the use of other flexible materials such as leather is not excluded.

[0031] The box is equipped with a sealing zipper 3, such as Figures 1-3 As shown, the starting point of the sealing zipper 3 is located on one side wall 2, and the ending point is located on the opposite side wall 2, with the zipper 3 extending through the bottom wall 9. Thus, when the sealing zipper 3 is open, as... Figure 4 As shown, one side of the box can be opened directly, forming an opening for the item 100 to enter and exit.

[0032] It should be noted that the figure exemplifies a case where the sealing zipper 3 penetrates the bottom wall 9, in which case opening one side of the box actually opens upwards (a top-opening door). However, in other embodiments, the sealing zipper 3 can also penetrate the top wall 1, in which case opening one side of the box actually opens downwards (a bottom-opening door).

[0033] Analysis of the above structure shows that, in this embodiment, when storing item 100, the microenvironmental protection sealing device simply involves opening the sealing zipper 3 and flipping up one side of the box to form a side opening, which is convenient and efficient. When placing item 100 into the receiving cavity, it is only necessary to hoist item 100 to the required level for horizontal insertion into the side opening, making operation convenient. The process of retrieving item 100 is the reverse of storing item 100, and it also has the same convenient and efficient effect.

[0034] As a preferred embodiment that is easy to manufacture and provides better sealing, the box body is composed of three membrane materials spliced ​​together. Specifically, the three membrane materials are a main membrane and two side membranes. The main membrane, in its unfolded state, is as follows... Figure 5 As shown, the two ends of the main membrane ( Figure 5 The two ends in the middle (up and down direction) are connected to form a ring structure, and are bent in sequence at the set position to form corners, thus forming the top wall 1, bottom wall 9 and opposite side walls 2 of the box. Figure 5 The connection points at both ends of the main membrane shown are actually located on the top wall 1, but in other embodiments, the connection points can also be located on the bottom wall 9. Two side membranes are connected at both ends in the width direction of the main membrane, forming two additional side walls 2. The connection can be achieved using thermofusion welding, with specific process parameters described in existing technology.

[0035] In this embodiment, the sealing zipper 3 is actually located on the main body film. Specifically, when installing the sealing zipper 3, a slit can be made at a relevant position on the main body film first, the sealing zipper 3 can be installed at the slit, and then heat fusion connection can be used.

[0036] The housing provided in the above embodiments is easy to manufacture, has stronger integration, fewer potential points of risk for air leakage / intake, and higher reliability. However, it should be noted that in other embodiments, it is not excluded that the top wall 1, bottom wall 9, and each side wall 2 may be made of independent membrane materials.

[0037] Furthermore, to facilitate operation by staff based on the site location, such as Figures 1-5 As shown, there are actually two sealing zippers 3, located at both ends of the main film, allowing openings at both ends for flexible selection by staff based on actual needs. However, it should be noted that other embodiments may also include the possibility of having only one sealing zipper 3.

[0038] For example Figures 1-5 The illustrated embodiment of the upward-opening door, to prevent the opened portion from accidentally closing, such as... Figure 5As shown, the top wall 1 is provided with a buckle 15, which is used to fix the opened part after the box is opened upward on one side. For example, one part of the buckle 15 can be fixed outside the top wall 1, and the other part can be fixed inside the side wall 2. After the side wall 2 is rolled up, the two parts of the buckle 15 can be buckled and connected.

[0039] In a more preferred embodiment, as shown in Figure 1 and Figure 4 The inside of the box is also provided with a buffer lining 4, which is made of flexible material, such as EVA material (prior art) or pearl wool. The six inner circumferential surfaces of the box are shown in the figure as being paved with the buffer lining 4, which can protect the articles 100 in all directions. At the same time, the buffer lining 4 also supports the box, improving the pressure-bearing and anti-deformation capacity of the box. However, in other embodiments, if the buffer lining 4 is provided, at least the buffer lining 4 should be paved on the four side walls 2. Compared with the scheme of paving the buffer lining 4, it can play a basic buffering role and the same supporting role.

[0040] Of course, the buffer lining 4 cannot affect the normal installation of the one-way valve 5, as shown in Figure 7 The buffer lining 4 is provided with a first avoiding opening 401 for avoiding the one-way valve 5.

[0041] Further, considering that the articles 100 contained may not be regular, for example, mechanical equipment may have a part extending longer. As shown in Figure 7 The buffer lining 4 is also provided with a containing opening 402 for avoiding the contained articles 100. The specific shape and size of the containing opening 402 are not limited here and can be set according to the actual articles 100.

[0042] As another preferred embodiment, as shown in Figures 1-4 The micro-environment protection and sealing device also includes a mobile chassis 8, which can support the box and move the box, facilitating the movement of the box by the staff. Specifically, the mobile chassis 8 includes a frame and a roller 14, as shown in Figure 2 The frame is provided with a roller mounting position 801, and the roller 14 can be mounted on the roller mounting position 801. The roller 14 is preferably a universal wheel, but other embodiments also do not exclude the case of using a roller 14 rotating on a fixed shaft. The frame is connected with the bottom wall 9 to support the box. There are two ways of connection here, one is direct connection, for example, directly bonding the bottom wall 9 on the frame. The second is indirect connection, as an embodiment of indirect connection, as shown in Figure 2As shown, the bottom wall 9 is connected with the thickened cover plate 11, and is connected with the rack through the thickened cover plate 11. The material of the thickened cover plate 11 can be consistent with the material of the box body. Here, thickening means that the thickness of the bottom is increased after the thickened cover plate 11 is connected, and does not mean that the thickness of the thickened cover plate 11 is thicker than the bottom wall 9. As shown in Figure 2 and Figure 6 As shown, the thickened cover plate 11 is provided with an ear 1101 around. When connecting the rack, the ear 1101 can be folded downward, and a bolt is used to pass through the ear 1101 to connect with the rack, at this time the ear 1101 is equivalent to the edge of the rack. In order to improve the connection strength, a rigid pressing plate 10 can be used to press the ear 1101 and connect with the rack. It should be pointed out here that the specific form of indirect connection is not only the above-mentioned thickened cover plate 11, but also other forms of transition connecting piece can be used for connection in other embodiments, for example, a locking hook can be provided on the box body, and the locking hook is locked with the rack to achieve connection.

[0043] Based on the above embodiments, in a further preferred embodiment, as shown in Figures 3-5 The embodiment also includes two annular straps 12, which pass around the top wall 1, the moving base 8 and the two opposite side walls 2, that is, the straps 12 bind the moving base 8 and the box body as a whole. In this way, when the box body is transported later, the lifting tool can be directly connected with the straps 12, and the whole can be lifted by lifting the straps 12, at this time the moving base 8 is equivalent to a tray, which is convenient for overall lifting.

[0044] In a further preferred embodiment, the box body is provided with a pull ring 13, the pull rings 13 are arranged in groups, and the number of groups of pull rings 13 is consistent with the number of straps 12. For the case of Figures 3-5 two straps 12, the pull ring 13 is also provided with two groups. In each group of pull rings 13, the number of pull rings 13 is at least two, and the pull rings 13 are arranged in intervals along the extension direction of the straps 12, and the straps 12 pass through the corresponding group of pull rings 13 correspondingly. Specifically, the pull ring 13 can be hot melt welded on the box body. The pull ring 13 can play a limiting role on the strap 12, avoid the strap 12 from deviating, and ensure the safety of lifting.

[0045] In other embodiments, in order to timely and accurately obtain the temperature, humidity and pressure in the containing cavity, temperature sensors, humidity sensors and pressure sensors are arranged inside the box body. In order to facilitate the observation of the sensor readings by the staff, as shown in Figure 1 The box body is also provided with an observation window 6, and the observation window 6 is made of transparent material, so that the staff can accurately obtain the readings of the sensors through the observation window 6. Of course, in the case where the observation window 6 and the buffer lining 4 exist, as shown in Figure 7As shown, the second avoiding opening 403 for avoiding the observation window 6 is also formed on the buffer lining 4.

[0046] In addition, as Figure 1 As shown, the top wall 1 is further provided with a file pocket 7 for placing the relevant instruction files of the article 100.
