[0019] 2. This invention rotates the threaded rod clockwise, causing two threaded blocks on the rod to move towards each other. The threaded blocks cause the four linkage rods to unfold vertically, thereby increasing the distance between the chassis and the ground, and raising the height of the chassis. This not only prevents rainwater from entering, but also allows for adjustment of the unfolding distance of the linkage rods in uneven terrain, keeping the chassis level.

[0020] 3. In this invention, the rotating block and the slide groove are rotated by a knob, and the docking frame moves along the slide groove by ball bearings. The docking frame moves downward and drives the lifting rod to make the inner arc tooth block and the outer convex tooth mesh. At this time, the chassis cannot be raised or lowered by rotating the threaded rod, thereby avoiding the chassis tilting caused by vibration and external accidental collision.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0032] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0033] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Example: A quick-assembly folding house, such as Figure 1 and Figure 2 As shown, the system includes a chassis 1, a main frame 2 fixedly mounted on the top of the chassis 1, and side wall panels 3 fixedly mounted on the left and right sides of the main frame 2, which are inserted into the chassis 1. Door and window wall panels 5, which are inserted into the chassis 1, are fixedly mounted on the front and rear sides of the side wall panels 3, and a fixed wall panel 4, which is inserted into the top of the door and window wall panels 5, is fixedly mounted on the top of the side wall panels 3.

[0036] The top of the chassis 1 has a docking groove 11 for connecting to the main frame 2. The main frame 2 adopts a horizontally oriented U-shaped structure. The main frame 2 has a leakage protection device 21, a five-hole socket 22, and a transport fixing hole 23. An acrylic door 51 is rotatably connected to the middle of the door and window wall panel 5, and a ventilation window 52 is rotatably connected to the acrylic door 51. Folding rubber strips are provided on the chassis 1, side wall panels 3, fixed wall panels 4, and door and window wall panels 5.

[0037] The side wall panel 3 is composed of internal wall panels, interlayer fireproof and heat-insulating materials and external alloy panels. The side wall panel 3, fixed wall panel 4 and door and window wall panel 5 have the same material composition. The chassis 1 is composed of internal anti-slip aviation floor mat, interlayer aluminum honeycomb core or extruded board and external alloy base plate.

[0038] like Figure 7 and Figure 8 As shown, the mating points of the chassis 1, side wall panels 3, fixed wall panels 4, and door and window wall panels 5 all utilize swivel fittings 8 with locking edges and rubber strips. Multiple chassis 1 are spliced ​​together. The chassis 1, side wall panels 3, fixed wall panels 4, and door and window wall panels 5 are folded along folding rubber strips for easy transport. The side wall panels 3 consist of internal wall panels, a layer of fireproof and thermally insulating material, and an external alloy panel. The external alloy panel is impact-resistant, while the internal wall panels and the layer of fireproof and thermally insulating material provide insulation. Swivel fittings 8 are fixedly installed between each component of the chassis 1, main frame 2, side wall panels 3, fixed wall panels 4, and door and window wall panels 5.

[0039] During installation, first place the base plate 1, then place the main frame 2 in the groove on top of the base plate 1, and level it according to the prompts of the acrylic level. Then install the front and rear fixed wall panels 4. After installation, the fixed wall panels 4 are in a drooping state. Then install the door and window wall panels 5. After installation, one person holds the door and window wall panels 5 to make them perpendicular to the base plate 1, while another person supports and lifts the fixed wall panels 4 to make them slightly higher than the height of the door and window wall panels 5. Adjust the angle between the fixed wall panels 4 and the door and window wall panels 5 to complete the assembly. The disassembly method of the present invention is the reverse of the above assembly sequence.

[0040] This invention allows for the connection of multiple chassis 1, main frame 2, fixed wall panels 4, and door and window wall panels 5 with the original building by removing one side wall panel 3, thus enabling expansion. The size and layout of the dormitory area can be flexibly adjusted according to needs to meet the usage requirements of different scenarios. At the same time, folding rubber layers are provided on chassis 1, main frame 2, fixed wall panels 4, and door and window wall panels 5, which can be folded along the folding rubber layers to reduce space and facilitate transportation.

[0041] like Figures 3 to 5 As shown, the bottom of the chassis 1 is provided with a foot 6, and a threaded rod 62 is provided between the chassis 1 and the foot 6. Two threaded blocks 63 are symmetrically arranged and threadedly connected to the threaded rod 62. A lower connecting block 61 is fixedly installed on the top of the foot 6, and an upper connecting block 66 is fixedly installed on the bottom of the chassis 1. Four linkage rods 64 are hinged between the two threaded blocks 63, the lower connecting block 61 and the upper connecting block 66, and the four linkage rods 64 form a rhomboid structure.

[0042] The threads on the threaded rod 62 are in opposite directions, and the two threaded blocks 63 are located on two different threads. A limit block 65 is fixedly installed at one end of the threaded rod 62, and a handle extending from the bottom of the chassis 1 is fixedly installed at the other end of the threaded rod 62.

[0043] By turning the handle, the threaded rod 62 is rotated, and the threaded blocks 63 on the threaded rod 62 move towards each other. The threaded blocks 63 cause the four linkage rods 64 to unfold vertically, thereby increasing the distance between the chassis 1 and the foot 6, thus realizing the adjustment of the height of the chassis 1. The limit block 65 prevents the threaded blocks 63 from moving off the threaded rod 62.

[0044] A slider is slidably connected to the top of the base 6, and a telescopic rod 67 is hinged to the top of the slider. The top of the telescopic rod 67 is fixedly connected to the chassis 1. Multiple telescopic rods 67 are provided, located at the top of the base 6 and near the corners. The telescopic rods 67 prevent the linkage rod 64 from tilting.

[0045] This invention rotates the threaded rod 62 clockwise, causing the two threaded blocks 63 on the threaded rod 62 to move towards each other. The threaded blocks 63 cause the four linkage rods 64 to unfold vertically, thereby increasing the distance between the chassis 1 and the foot 6 and raising the height of the chassis 1. This not only prevents rainwater from entering the ground, but also allows for adjustment of the unfolding distance of the linkage rods 64 in uneven terrain, keeping the chassis 1 in a horizontal state.

[0046] like Figure 5 and Figure 6 As shown, a lifting rod 74 is slidably connected to the inside of the chassis 1. An inner arc toothed block 75 is fixedly installed at the bottom of the lifting rod 74, and an outer convex toothed block 76 is fixedly installed at the end of the linkage rod 64. The inner arc toothed block 75 and the outer convex toothed block 76 mesh. When the lifting rod 74 slides down, the inner arc toothed block 75 meshes with the outer convex toothed block 76, preventing the linkage rod 64 from rotating. This prevents the threaded rod 62 from being accidentally touched from the outside and causing it to rotate, which would cause the chassis 1 to tilt.

[0047] A knob 7 is rotatably connected to the top of the chassis 1, and a docking frame 73 is fixedly installed on the top of the lifting rod 74. The docking frame 73 adopts a U-shaped structure and slides up and down along the inside of the chassis 1. A rotating block 71 is fixedly installed at the bottom of the knob 7. A groove 72 is opened on the outer wall of the rotating block 71. A ball is rolled on the side of the docking frame 73 facing the groove 72. The ball rolls in the groove 72. The groove 72 adopts a stepped structure and forms a ring around the outer wall of the rotating block 71.

[0048] Rotating the knob 7 causes the rotating block 71 and the slide 72 to rotate, and the docking frame 73 moves along the slide 72 via the ball bearings. However, since the docking frame 73 is restricted by the chassis 1 and cannot be selected, the docking frame 73 exhibits a vertical movement path.

[0049] The present invention rotates the rotating block 71 and the slide 72 by the knob 7, and the docking frame 73 moves along the slide 72 by the ball bearing. The docking frame 73 moves downward and drives the lifting rod 74 to make the inner arc tooth block 75 and the outer convex tooth 76 mesh. At this time, the chassis 1 cannot be raised or lowered by rotating the threaded rod 62, thereby avoiding vibration and external accidental collision that cause the chassis 1 to tilt during lifting or lowering.

[0050] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
