[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figures 1-10 As shown, an embodiment of the present application proposes a fast-assembly detachable large-plate square cabin, including a cabin body 1, which is spliced ​​by a plurality of first connecting plates 2 and a plurality of second connecting plates 3. The first connecting plates 2 and the second connecting plates 3 can be spliced ​​into a flat large plate. After six large plates are spliced ​​according to needs, the six large plates are assembled and assembled by existing bolts and connectors to form a square cabin. That is to say, when the first connecting plates 2 and the second connecting plates 3 need to be connected vertically, they need to be installed with bolts using existing connectors. However, the assembly between the first connecting plates 2 and the second connecting plates 3 required for each large plate abandons the existing bolt installation and adopts a simpler and more convenient installation method. The specific contents are as follows:

[0031] The first connecting plate 2 is provided with a plurality of plug-in slots 4 on the four sides, and the second connecting plate 3 is provided with a plurality of plug-in plates 5 on the four sides, which are used to be plugged into the plug-in slots 4. Positioning slots 6 are provided on the opposite sides of the length direction of the plug-in plates 5. A clamping portion 9 is installed inside the plug-in slot 4. An adjustment mechanism is installed between the first connecting plate 2 and the second connecting plate 3. When the plug-in plate 5 is inserted into the plug-in slot 4, the clamping portion 9 is clamped in the positioning slot 6 through the adjustment mechanism. In the existing installation of the square cabin, the first connecting plate 2 and the second connecting plate 3 are installed by means of connecting members and bolts, while the first connecting plate 2 and the second connecting plate 3 of the present application are installed in the same manner. During installation, first place the second connecting plate 3 opposite to the side of the first connecting plate 2, and then insert the plug-in plate 5 into the plug-in slot 4. At this time, the plug-in plate 5 is located in the plug-in slot 4, and one side of the first connecting plate 2 is in contact with one side of the second connecting plate 3. At this time, the clamping portion 9 is clamped in the positioning slot 6 through the adjusting member 8, thereby indirectly fixing the plug-in plate 5 in the plug-in slot 4, thereby realizing quick installation of the first connecting plate 2 and the second connecting plate 3. Compared with the method of using bolts and connectors, no tools are required and the installation is convenient, thereby improving the installation efficiency of the first connecting plate 2 and the second connecting plate 3, thereby indirectly improving the overall installation efficiency of the cabin.

[0032] like Figure 2 、 Figure 8 and Figure 9 As shown, in some embodiments, the clamping portion 9 includes a mounting groove 901 opened on one side of the length of the plug-in slot 4, and a positioning plug-in plate 902 is slidably inserted in the mounting groove 901. A resistance spring 903 is installed between the positioning plug-in plate 902 and the mounting groove 901. When the positioning plug-in plate 902 is inserted into the positioning groove 6, the positioning plug-in plate 902 is moved by adjusting the mechanism. When the plug-in plate 5 is inserted into the plug-in slot 4, the limit plate 13 is located at the opening of the positioning groove 6, thereby blocking the opening of the positioning groove 6. At this time, the plug-in plate 5 is inserted into the plug-in slot 4. In this embodiment, the end of the plug-in plate 5 is arc-shaped. At this time, the end of the plug-in plate 5 is in contact with the positioning plug-in plate When the locking cam 902 is in contact with the locking cam 903, the locking cam 902 retracts into the corresponding mounting groove 901, and the corresponding interference spring 903 is compressed until one side of the first connecting plate 2 is in contact with the one side of the second connecting plate 3. At this time, the limiting plate 13 is moved by the adjusting member 8, so that the limiting plate 13 moves away from the opening of the positioning groove 6. During the movement of the limiting plate 13, the compressed interference spring 903 is reset due to its own elastic deformation characteristics, thereby forcing the positioning plate 902 to move, so that the positioning plate 902 moves toward the opening of the corresponding mounting groove 901 until the positioning plate 902 is inserted into the positioning groove 6, thereby achieving the effect of quick installation.

[0033] like Figure 2 、 Figure 8 and Figure 9As shown, in some embodiments, the plug-in board 5 is internally constructed with a sliding cavity 14 that is connected to the positioning groove 6. The adjustment mechanism includes a driving plate 15 that is slidably installed in the sliding cavity 14. A limit plate 13 is slidably installed in the positioning groove 6 along its length direction. A connecting rod 16 is hinged between the limit plate 13 and the driving plate 15. An adjusting member 8 that acts on the driving plate 15 is installed on the first connecting plate 2. When the plug-in board 5 is inserted into the plug-in groove 4, the driving plate 15 is moved by the adjusting member 8. That is to say, when the plug-in board 5 is inserted into the plug-in groove 4, the positioning plug-in plate 902 is also inserted into the corresponding positioning groove 6. At this time, when the first connecting plate 2 and the second connecting plate 3 need to be disassembled, it is only necessary to use the adjusting member 8 to move the driving plate 15. Movement, that is, when the driving plate 15 is moved by the adjusting member 8, because the driving plate 15 is hinged to the connecting rod 16, the movement of the driving plate 15 will drive the connecting rod 16 to move, and because one end of the connecting rod 16 is hinged to the limit plate 13, the movement of the driving plate 15 through the connecting rod 16 will cause the limit plate 13 to move, so that when the driving plate 15 moves, multiple limit plates 13 will simultaneously move away from or approach the axis direction of the plug-in plate 5 through multiple hinged rods, so that the limit plate 13 pushes the corresponding positioning plug-in plate 902 until the limit plate 13 is flush with the opening of the positioning slot 6 so that the positioning plug-in plate 902 is disengaged from the positioning slot 6, so that the plug-in plate 5 can be pulled out of the plug-in slot 4, which is more convenient for disassembly.

[0034] like Figure 5 and Figures 8-10As shown, in some embodiments, the first connecting plate 2 is internally constructed with a cavity 801 that is connected to the plug-in slot 4, the adjusting member 8 includes a sliding plate 802 that is slidably installed in the cavity 801, and the plug-in slot 4 is symmetrically constructed with two baffles 803, which are used to contact one end of the plug-in plate 5, one end of the driving plate 15 is located outside the sliding cavity 14, the driving plate 15 is constructed with a convex plate 804 and the convex plate 804 is located outside the sliding cavity 14, and a transmission plate 805 is constructed on the sliding plate 802, and a through slot 7 for the driving plate 15 to pass through is opened on the transmission plate 805, that is, when the plug-in plate 5 is plugged into the plug-in slot 4 and one side of the first connecting plate 2 is fitted with the second connecting plate 3, at this time, the end of the plug-in plate 5 located in the plug-in slot 4 is just in contact with the two baffles 80 3 fits, and at this time, the sliding plate 802 is moved, and the movement of the sliding plate 802 indirectly drives the transmission plate 805 constructed on the sliding plate 802 to move. The through slot 7 on the transmission plate 805 is for the end of the driving plate 15 to pass through. During the movement of the transmission plate 805, the end of the driving plate 15 will pass through the transmission plate 805 and contact the convex plate 804. Therefore, as the transmission plate 805 moves, the convex plate 804 is pushed to move, thereby indirectly moving the driving plate 15, so that the driving plate 15 moves toward the opening of the corresponding plug-in slot 4, thereby cooperating with the pair of connecting rods 16 to make the multiple limit plates 13 move toward the opening direction of the corresponding positioning slot 6. Because when the sliding plate 802 moves, multiple driving plates 15 on the same side will move at the same time, it is more convenient to use.

[0035] like Figure 5-Figure 8 As shown, in some embodiments, a rotating disk 17 is installed in the first connecting plate 2 through a rotating shaft, and a column 18 is eccentrically constructed on the rotating disk 17. A movable groove 19 is provided on the sliding plate 802, and the column 18 slides tangentially in the movable groove 19. When the rotating disk 17 is rotated, the rotating disk 17 rotates to drive the column 18 to move. Because the column 18 slides tangentially with the movable groove 19, when the rotating disk 17 rotates, the column 18 moves in the movable groove 19 relative to the sliding plate 802. Compared with the moving method of driving the sliding plate 802, the method of using the rotating disk 17 to rotate and drive the sliding plate 802 can effectively prevent the first connecting plate 2 from having more sliding grooves for the sliding plate 802 to move. It is only necessary to provide a circular groove for the rotating disk 17 to rotate on the first connecting plate 2. The rotating disk 17 is rotatably installed in the circular groove, thereby effectively preventing external impurities from entering the first connecting plate 2, and driving the sliding plate 802 by rotating the rotating disk 17 is more labor-saving.

[0036] like Figure 6-Figure 8As shown, in some embodiments, a rectangular block 20 is constructed in the middle of one end of the rotating shaft, an adjusting sleeve 21 is provided on the sliding sleeve of the rectangular block 20, a torsion spring 22 is provided on the rotating shaft, one end of the torsion spring 22 is connected to the first connecting plate 2, and the other end of the torsion spring 22 is connected to the rotating disk 17, a baffle 23 is constructed at the end of the rectangular block 20, and a connecting spring 11 is installed between the baffle 23 and the adjusting sleeve 21. That is to say, when the positioning plug-in plate 902 is inserted into the positioning slot 6, it is necessary to rotate the rotating disk 17 so that the limit plate 13 can be moved to facilitate the alignment. When the corresponding plug-in board 5 is pulled out from the plug-in slot 4, pressing the adjustment sleeve 21 will cause the adjustment sleeve 21 to be sleeved on the rectangular block 20. At this time, rotating the adjustment sleeve 21 can move the rotating shaft, causing the rotating disk 17 to rotate. At this time, the torsion spring 22 is in a tightened state. When the adjustment sleeve 21 is released, the adjustment sleeve 21 is reset due to the connecting spring 11, so that the adjustment sleeve 21 is located at the rotating shaft, and the rotating disk 17 is reset due to the torsion spring 22, so that the limit plate 13 is reset, so that the positioning groove 6 can be used for the positioning plug-in board 902 to be inserted.

[0037] like Figure 2 、 Figure 3 and Figure 9 As shown, in some embodiments, the plug board 5 is slidably installed on the second connecting plate 3, and a transmission assembly 12 for driving the plug board 5 to move is installed on the second connecting plate 3. The transmission assembly 12 is used to form the plug board 5 to be stored in the second connecting plate 3. When one side of the second connecting plate 3 does not need to be planarly connected to the first connecting plate 2, the plug board 5 that is not needed can be stored in the second connecting plate 3 through the transmission assembly 12, thereby reducing the space occupied by the plug board 5.

[0038] like Figure 2 and Figure 5 As shown, in some embodiments, the transmission assembly 12 includes a mounting plate 1201 connected to multiple plug-in boards 5 on the same side, and an adjusting screw 1202 that is threadedly engaged with the mounting plate 1201 is rotatably installed inside the second connecting plate 3. Two mutually meshing bevel gears 1203 are rotatably installed on the second connecting plate 3, one of the bevel gears 1203 is connected to the adjusting screw 1202, and an adjusting disk 1204 is installed on the other bevel gear 1203. Rotating the adjusting disk 1204 will cause the bevel gear 1203 to rotate. Because the two bevel gears 1203 are meshed with each other, the adjusting screw 1202 will rotate. Because the mounting plate 1201 is threadedly engaged with the adjusting screw 1202, the mounting plate 1201 will move. Because the mounting plate 1201 is connected to multiple plug-in boards 5, the plug-in boards 5 on the same side will move at the same time, which is more convenient when adjusting the movement of the plug-in boards 5.

[0039] like Figure 2 、 Figure 4 、 Figure 8 and Figure 9As shown, in some embodiments, the number of positioning grooves 6 opened on one side of the plug-in board 5 is multiple and distributed in a linear array along its length direction. Because the number of positioning grooves 6 is consistent with the number of positioning plug-ins 902, the number of positioning plug-ins 902 is also multiple and distributed on two opposite sides of the plug-in slot 4. The multiple positioning grooves 6 and positioning plug-ins 902 improve the installation effect, making the first connecting plate 2 and the second connecting plate 3 more secure after installation. The positioning groove 6 has an inclined angle, and the angle between the positioning groove 6 and the plug-in slot 4 toward the corresponding plug-in slot 4 opening is less than forty-five degrees. The two opposite edges of the free end of the plug-in board 5 are constructed as inclined surfaces 10, the baffle 803 contacts the inclined surface 10, and the transmission plate 805 and the convex plate 804 are attracted to each other by opposite charges. Specifically, the transmission plate 805 and the convex plate 804 are made of magnet material. When the plug-in board 5 is inserted into the plug-in slot 4, the transmission plate 805 can be adsorbed on When the locking plate 802 is in the locking position, the locking plate 802 is locked and the locking plate 803 is locked.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
