DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In modern society, as a crystallization of science and engineering wisdom, shelters play an indispensable role in emergency rescue, military operations, medical support and other fields due to their unique structure and versatility. Traditional shelter designs often focus on their robustness, protection and mobility to ensure that they can provide stable use space in various harsh environments, but they ignore the expansion performance of shelters during use.

[0032] At present, the size of the internal storage space of the shelter depends on its structural design. Most of the current shelter structures are designed to be fixed and non-detachable. This means that when the shelter is in actual use, if there is a change in operational requirements, it is impossible to modify the structure of the shelter on the spot, so that multiple shelters can be installed together to achieve rapid expansion of the internal space of the shelter. Secondly, after multiple shelters are spliced ​​and combined, the internal storage space is completely occupied, resulting in the inability to stack and store the disassembled parts in time when the shelter structure is modified, which can easily lead to property loss.

[0033] In order to solve the above technical defects, the inventor provides a cabin structure and method with stacking storage function.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-3 As shown, in a first aspect of an embodiment of the present invention, a cabin structure with a stacking storage function is provided, comprising: an upper frame and a lower frame, wherein a cabin top assembly is provided at the top of the upper frame, and a cabin bottom assembly is provided at the bottom of the lower frame, and the upper frame and the lower frame are connected by an extension assembly, and the extension assembly is used to connect an external cabin, so that the external cabin is located on the top of the upper frame or on the lower frame; specifically, the upper frame comprises an upper end beam 7 and an upper cross beam, and the upper cross beam comprises a front upper cross beam 6 and a rear upper cross beam 8, and two upper end beams 7 are provided, and the two upper end beams 7 are connected by the front upper cross beam 6 and the rear upper cross beam 8; the lower frame comprises a lower end beam and a lower cross beam 5, There are also two lower end beams, which are connected by two lower cross beams 5; the wave plate assembly is arranged on the upper frame, the lower frame and the extension assembly, and the wave plate assembly is used to seal the upper frame, the lower frame and the extension assembly; the wave-transmitting plate assembly includes a front wave-transmitting plate 3, a top wave-transmitting plate 9, an end wave-transmitting plate 11 and a bottom wave-transmitting plate 12, wherein the front wave-transmitting plate 3 and the end wave-transmitting plate 11 are installed on the extension assembly, and the top wave-transmitting plate 9 is installed on the upper frame; the stacking storage assembly is arranged in the lower frame and is slidably connected to the lower frame for storing the cabin top assembly and the cabin bottom assembly; specifically, the stacking storage assembly is slidably connected to the bottom of the lower cross beam 5. When in use, the square cabin is divided into three parts: an upper frame, a lower frame and a wave plate assembly. The wave plate assembly seals the upper frame, the lower frame and the expansion assembly to form a square cabin accommodation space. The cabin roof assembly is installed on the top of the upper frame, and the cabin bottom assembly is installed on the bottom of the lower frame. The upper and lower frames are connected by the expansion assembly. When it is necessary to expand the internal space of the square cabin and form a multi-level square cabin, it is only necessary to disassemble the cabin roof assembly and the cabin bottom assembly, leak out the expansion assembly, and then connect multiple square cabins together by bolts to expand the square cabin vertically or horizontally, thereby realizing the assembly of multi-level square cabins and expanding the accommodation space of the square cabin. This effectively solves the technical defect in the prior art that the square cabin structure is fixed and cannot be disassembled, and the internal space of the square cabin cannot be quickly expanded on the spot; secondly, a stacking storage assembly is slidably installed in the lower frame. When the square cabin is expanded and renovated, the parts removed from the square cabin can be directly placed in the stacking storage assembly to avoid the occurrence of property loss problems.

[0035] Furthermore, if Figure 1 and Figure 2As shown, the expansion component includes a column 1 and an expansion piece 101. The column 1 is provided with multiple columns, one end of the multiple columns 1 is connected to the upper frame, and the other end is connected to the lower frame. The column 1 is axially perpendicular to the upper frame and the lower frame, and supports the upper frame and the lower frame to form a accommodating space. The expansion piece 101 is arranged on the top of the column 1, and the external cabin is installed on the expansion piece 101. It can be understood that, since the extension piece 101 is installed on the top of the column 1, when the external cabin is installed on the top of the upper frame, the cabin top assembly on the top of the upper frame and the cabin bottom assembly on the bottom of the external cabin are disassembled, and the extension piece 101 on the external cabin is also exposed. When the two cabins are assembled together to expand the internal space of the cabin, the external cabin can be hoisted to the top of the upper frame, or the outside of the lower frame by a lifting device, so that the external cabin can be expanded in multiple stages along the top of the upper frame or the outside of the lower frame; in terms of installation, when the two cabins are stacked vertically or horizontally, it is only necessary to connect the two relative extension pieces 101 together with sharp bolts and lock them, so as to realize the combination of multiple cabins.

[0036] In order to further understand the structure of the extension 101, Figure 2 As shown, the extension piece 101 is provided with a first connection port, a second connection port and a third connection port. The first connection port and the second connection port have the same structure and are interconnected. The first connection port, the second connection port and the third connection port are axially perpendicular to each other. When assembling the two shelters together, the first connection port is used to install the external shelter on one side of the column 1, that is, Figure 1 In the width direction of the central cabin, multiple cabins are arranged in a long strip; the second connection port is used to install the external cabin on the other side of the column 1, that is, Figure 1 The length direction of the central cabin; the third connection port is used to install the external cabin on the top of the column 1, that is, Figure 1 The top of the central cabin can be expanded in different directions to meet temporary operation needs on site, thus improving the expansion performance of the cabin.

[0037] like Figure 3 As shown, the stacking storage assembly includes a storage drawer 10, with guide rails 17 on opposite sides of the storage drawer 10, a slide groove is provided at the bottom of the lower crossbeam 5, and the guide rails 17 are slidably connected in the slide groove, and a forklift hole is provided on the outer side of one of the guide rails 17; the storage drawer 10 is provided with a bottom wave-transmitting plate 12, a bottom beam 15 and a forklift groove 14, the bottom wave-transmitting plate 12 is arranged on the inner bottom surface of the storage drawer 10, and the bottom beam 15 is provided with multiple forklift grooves along the length of the storage drawer 10, and the forklift groove 14 is located in the middle of the storage drawer 10. Figure 3It can be seen that the bottom beam 15 divides the storage drawer 10 into multiple stacking storage areas, and different types of parts can be placed in each stacking storage area. For example, the top beam 13 and the upper bottom beam 16 parts are placed in the stacking storage area at the end of the storage drawer 10; when the cabin is transported and moved, the stacking storage assembly and the cabin as a whole can be moved by the cooperation between the forklift and the forklift slot 14. When the cabin is not transported, the forklift hole sealing plate 4 is used to block the forklift hole. Finally, a personnel door 2 is provided on the front wave-transmitting plate 3, and the personnel door 2 is provided to facilitate the operator to enter and exit.

[0038] In a second aspect, a method for using a shelter structure with a stacking storage function is provided, wherein the method is performed using the shelter structure as described above. Figure 4 As shown, including: S101. When expanding the cabin, the cabin roof assembly and the cabin bottom assembly are disassembled to allow the expansion assembly to leak out, and the external cabin is connected to the expansion assembly so that the external cabin is installed on the top of the upper frame or the outside of the lower frame; illustratively, when it is necessary to expand the internal space of the cabin and form a multi-level cabin, it is only necessary to disassemble the cabin roof assembly and the cabin bottom assembly to allow the expansion assembly to leak out, and then multiple cabins can be connected together through the cooperation of bolts and the expansion assembly to allow the cabin to be expanded vertically or horizontally, thereby realizing the assembly of multi-level cabins and expanding the accommodation space of the cabin, which effectively solves the technical defect in the prior art that the cabin structure is fixed and cannot be disassembled, and the internal space of the cabin cannot be quickly expanded on the spot. S102, stacking storage, disassembling the cabin top assembly and cabin bottom assembly, manually pulling out the storage drawer, so that the cabin top assembly and cabin bottom assembly are stored in the storage drawer. Exemplarily, the stacking storage assembly is slidably installed in the lower frame, and when the square cabin is expanded and renovated, the storage drawer is manually pulled out, and the parts disassembled from the square cabin are directly placed in the stacking storage assembly to avoid the occurrence of property loss.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
