[0025] Embodiments:

[0026] Grain is both a heat-sensitive material and a very strong hygroscopic material. High temperature and high humidity environment can easily cause the quality of grain to decrease, causing the grain in the local or even whole warehouse to heat and mildew. Therefore, the grain storage warehouse must have good heat insulation, moisture-proof and airtight performance.

[0027] In the prior art, the door and window installed on the grain storage warehouse realizes the sealing between the door and window leaf and the frame body by means of tightly pressing the rubber strip. However, when there is a pressure difference between the inside and outside of the grain storage warehouse, the rubber strip on the door and window is affected by the pressure difference, and there is a gas leakage phenomenon, and the sealing effect is poor.

[0028] In order to overcome the above technical defects, the purpose of the embodiments of the present application is to provide a low-temperature grain storage and air conditioning special heat-insulating and airtight door and window, which can at least improve the airtightness and heat insulation function of the door and window to a certain extent by setting an automatic inflation and deflation sealing strip.

[0029] Next, the heat-insulating and airtight door and window in the example embodiments will be described in more detail in conjunction with the accompanying drawings.

[0030] Figure 1 The structure schematic diagram of the low-temperature grain storage and air conditioning special heat-insulating and airtight door and window provided by the embodiments of the present application is shown.

[0031] Illustratively, as shown in Figure 1 The low-temperature grain storage and air conditioning special heat-insulating and airtight door and window provided by the embodiments of the present application includes a door and window frame 1, a door and window leaf 2 and an automatic inflation and deflation rubber strip 3.

[0032] Specifically, the door and window frame 1 is used for being installed on the wall; the door and window leaf 2 is installed on the door and window frame 1 through a hinge 4; the automatic inflation and deflation rubber strip 3 is arranged on the side of the door and window leaf 2 close to the door and window frame 1. The automatic inflation and deflation rubber strip has a first state and a second state. When the automatic inflation and deflation rubber strip is in the first state, the door and window leaf is closed with the door and window frame, the automatic inflation and deflation rubber strip is in abutment with the side wall of the door and window frame 3 to realize heat insulation and sealing; when the automatic inflation and deflation rubber strip 3 is in the second state, the door and window leaf 2 is opened and closed with the door and window frame 1, and the automatic inflation and deflation rubber strip 3 is not in contact with the side wall of the door and window frame 1.

[0033] In an embodiment, the door and window leaf 2 comprises a mounting portion 21 and a glass leaf, the mounting portion 21 is on the side of the door and window leaf close to the door and window frame 1, and the automatic inflatable and deflatable rubber strip 3 is clamped in the mounting portion 21. The glass leaf is on the side of the door and window leaf 2 far from the door and window frame 1, and the hinge 4 is connected with the glass leaf.

[0034] In an embodiment, in order to facilitate the installation and replacement of the automatic inflatable and deflatable rubber strip 3, a clamping groove 22 is arranged on the side of the mounting portion 21 far from the door and window frame, and the air nozzle 31 is connected on the side of the automatic inflatable and deflatable rubber strip 3 far from the door and window frame 1, and the air nozzle 31 is arranged in the clamping groove 22. In other words, the automatic inflatable and deflatable rubber strip 3 is clamped with the mounting portion 21 by arranging the air nozzle 31 in the clamping groove 22.

[0035] Further, the user inflates or deflates the automatic inflatable and deflatable rubber strip 3 through the air nozzle 31. When the automatic inflatable and deflatable rubber strip 3 is inflated or deflated through the air nozzle, the automatic inflatable and deflatable rubber strip 3 is in the first state; when the automatic inflatable and deflatable rubber strip 3 is deflated through the air nozzle 31, the automatic inflatable and deflatable rubber strip 3 is in the second state.

[0036] In a possible implementation, when the door and window is sealed and heat-insulated, the door and window leaf 2 is closed with the door and window frame 1, and there is a gap between the door and window leaf 2 and the door and window frame 1. The automatic inflatable and deflatable rubber strip 3 is inflated, so that the automatic inflatable and deflatable rubber strip 3 abuts against the side wall of the door and window frame 1, to realize the sealing and heat-insulation of the door and window. Especially when fumigation or pressure maintenance is carried out in the grain storage warehouse, the air-tight film does not need to be covered inside, the pressure maintenance is longer, the heat-insulation effect is better, and the energy consumption for storing grain is lower.

[0037] When the door and window is opened, the door and window leaf 2 is closed with the door and window frame 1, the automatic inflatable and deflatable rubber strip 3 is deflated, so that the automatic inflatable and deflatable rubber strip 3 does not contact with the side wall of the door and window frame 1, and there is a gap between the door and window leaf 2 and the door and window frame 1. The pressure difference between the inside and outside of the grain storage warehouse is gradually balanced, the user can open the door and window conveniently, the damage to the automatic inflatable and deflatable rubber strip 3 when the door and window is opened and closed is reduced to some extent, the service life of the automatic inflatable and deflatable rubber strip 3 is effectively prolonged, the sealing and heat-insulation of the door and window are further improved, the door and window is more smooth to open and close, the requirement for the quality of the door and window lock is reduced, and the installation and debugging of the door and window are more convenient.

[0038] Further, when the automatic inflatable and deflatable rubber strip 3 is in the first state, the automatic inflatable and deflatable rubber strip 3 expands towards the door and window frame 1, so that the automatic inflatable and deflatable rubber strip 3 fully contacts with the side wall of the door and window frame 1, and the heat-insulation air-tightness is further improved. The first limiting stop 23 is integrally formed on the mounting portion 21.

[0039] Further, in order to make the automatic inflatable and deflatable rubber strip 3 expand towards the door and window frame 1 when in the first state, the side wall of the door and window frame 1 near the mounting portion 21 is L-shaped; the second limiting strip 24 is integrally formed on the mounting portion 21, and the first limiting strip 23 and the second limiting strip 24 are combined to make the automatic inflatable and deflatable rubber strip 3 expand towards the L-shaped side wall of the door and window frame 1. Specifically, Figure 1 The direction of the arrow is the expansion direction of the automatic inflatable and deflatable rubber strip 3.

[0040] Further, in order to fit the L-shaped side wall of the door and window frame 1 and make the automatic inflatable and deflatable rubber strip 3 contact the side wall more fully, the automatic inflatable and deflatable rubber strip 3 is rectangular, and when in the first state, the automatic inflatable and deflatable rubber strip 3 directly abuts against the L-shaped side wall of the door and window frame 1, thereby improving the air tightness of the door and window.

[0041] Figure 1 The heat preservation and sealing door and window is provided with the automatic inflatable and deflatable rubber strip 3, which can be inflated and deflated when the door leaf 2 and the door and window frame 1 are closed, so that the automatic inflatable and deflatable rubber strip 3 is in the first state and abuts against the side wall of the door and window frame 1 to achieve heat preservation and sealing. When the door leaf 2 and the door and window frame 1 are closed, the automatic inflatable and deflatable rubber strip 3 is deflated, so that the automatic inflatable and deflatable rubber strip 3 does not contact the side wall of the door and window frame 1, and a gap exists between the door leaf 2 and the door and window frame 1 to balance the pressure difference between the inside and outside of the grain storage warehouse, facilitate opening of the door and window, reduce damage to the automatic inflatable and deflatable rubber strip 3 to a certain extent, prolong the service life of the automatic inflatable and deflatable rubber strip 3, and further improve the heat preservation and sealing performance of the door and window.

[0042] In a possible implementation, when the door and window is heat preserved and sealed, as shown in Figure 2 The two symmetrically arranged automatic inflatable and deflatable rubber strips 3 are inflated to the first state after the casement door is closed, so as to be pressed towards the middle and be sealed.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
