[0010] The present invention provides a mobile house with a side wall contraction type. It has the following beneficial effects: 1. For this mobile house with a side wall contraction type, chutes are provided on both sides of the front and back of the housing, and guide rails are arranged inside the chutes. By applying an external force to push the main board to move, the main board drives the side strips to displace. The thin strips at the top of the side strips slide along the inner side of the guide rails, thereby ensuring the basic condition for the device to quickly contract and paving the way for saving storage space for the mobile house.

[0011] 2. For this mobile house with a side wall contraction type, the bottom of the side strip slides along the notch in the inner cavity of the housing. The guide rails facilitate the auxiliary support for the maintenance device and the side strips, preventing the maintenance device or the side strips from deforming and sagging after long-term use. The cross strip is located between several plates. The cross strip is a rubber layer connecting several plates. Several plates are squeezed and contracted together. The cross strip forms a folding trend. Then, through the combined use of the folding member, the plates and the cross strip, the function of quickly contracting the device is ensured. Thus, the space inside the housing is reserved, with flexible adjustment, convenient disassembly, no redundant and cumbersome steps, and effectively saving the space occupied by the mobile house.

[0012] 3. For this mobile house with a side wall contraction type, the shaft rod pushes against the innermost side of the guide rail and continues to displace. The bending degree of the vertical plate becomes larger, and the vertical plate deforms outward. The vertical plate squeezes the opening and closing plate, and the opening and closing plate deforms. The torsion member buffers the tension of the opening and closing plate. The opening and closing plate pushes the thin plate to displace synchronously. The wiping member moves along with the displacement of the thin plate. The thin plate swings to wipe the inner wall of the mobile house, thereby improving the cleaning of the inner wall of the house and realizing the function of a clean house, saving the labor intensity of manual cleaning.

[0013] 4. For the sidewall-contracting mobile house, the other end of the square plate is fixed to the bottom of the inner sidewall of the housing. The square plate is stably held by the housing. The chuck is inserted into the inner chute of the square plate. The pressing shaft contains a rod inside, and the rod on the pressing shaft extends into the inner cavity of the square plate. The chuck squeezes the rod on the pressing shaft and slides downward. The pressing shaft impacts the slider to displace, and the slider gradually displaces along the inner cavity of the mounting plate and contacts the universal wheel. The universal wheel is squeezed and fixed. Thus, when the house is being contracted, it prevents the universal wheels at the bottom from being affected and shaking, improving the comfort of living in the house.

[0014] 5. For the sidewall-contracting mobile house, the main board slides along the central axis and the outer surface of the laminar plate. The clamping part slides under the guidance of the central axis. The clamping part drives the sweeping head to move synchronously. The sweeping head wipes the interior. The dust after wiping falls on the upper surface of the laminar plate. And the middle part of the laminar plate is relatively concave, and the dust gradually accumulates inside the laminar plate. Opening the leakage cover can complete the acceptance, thus ensuring that the device has the function of quickly cleaning the interior, keeping the top environment clean, and achieving the purpose of convenient cleaning.

Detailed implementation mode

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and the detailed implementation mode. The examples of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form.

[0019] When the house is regularly cleaned, due to the relatively high distance at the top, cleaning is very inconvenient. Therefore, when the main board 61 moves, the main board 61 drives the card 33 fixedly installed at the top to move synchronously. The main board 61 slides along the outer surface of the central axis 34 and the laminate 32. The card 33 slides under the guidance of the central axis 34, and the card 33 drives the sweeper 35 to move synchronously. The sweeper 35 wipes the interior, and the dust after wiping falls on the upper surface of the laminate 32. Moreover, the middle part of the laminate 32 is relatively concave, and the dust gradually accumulates inside the laminate 32. Opening the leakage cover 36 can complete the acceptance, thereby ensuring that the device has the function of quickly cleaning the interior, ensuring the cleanliness of the top environment, and achieving the purpose of convenient cleaning.

[0020] Embodiment 2: Please refer to Figure 1 , Figure 9 , Figure 10 , the present invention provides a technical solution: A reinforcement device 4 is movably installed at the bottom of the machine base 1, and the reinforcement device 4 is used to adjust the stability state of the mobile house; The reinforcement device 4 includes a placement plate 41. A universal wheel 42 is movably installed in the middle of the inner cavity of the placement plate 41. A notch is provided on the left side wall of the placement plate 41, and a slider 44 is slidably connected to the notch on the side wall of the placement plate 41. A pressing shaft 43 is fixedly installed inside the placement plate 41. A square plate 45 is fixedly installed at the bottom of the inner side wall of the housing 2. The pressing shaft 43 is composed of an outer shell and a rod. The top of the rod on the pressing shaft 43 extends to the chute of the square plate 45. A chuck 46 is inserted and installed in the middle of the side of the square plate 45 close to the placement plate 41. The chuck 46 is inserted into the inner chute of the square plate 45. The pressing shaft 43 contains a rod, and the rod on the pressing shaft 43 extends into the inner cavity of the square plate 45. The square plate 45 is connected to the placement plate 41 through the pressing shaft 43. The bottom end of the rod on the pressing shaft 43 is fixedly connected to the slider 44. The diameter of the chuck 46 is larger than the diameter of the pressing shaft 43, and the included angle between the chuck 46 and the square plate 45 is ninety degrees. The rotating shaft on the universal wheel 42 is embedded and installed inside the placement plate 41. The square plate 45 is of a cube structure.

[0021] When the house is shrunk, the house moves, and the bottom of the house is easily affected by the vibration at the top and shakes. Therefore, when the bottom of the house needs to be reinforced, when the main board 61 moves, it gradually slides to the chuck 46. The chuck 46 is hit and displaced. The other end of the square plate 45 is fixed to the bottom of the inner side wall of the housing 2. The square plate 45 is stabilized by the housing 2. The chuck 46 is inserted into the inner chute of the square plate 45. The pressing shaft 43 contains a rod, and the rod on the pressing shaft 43 extends into the inner cavity of the square plate 45. The chuck 46 squeezes the rod on the pressing shaft 43 and slides downward. The pressing shaft 43 hits the slider 44 and displaces. The slider 44 gradually displaces along the inner cavity of the placement plate 41 and contacts the universal wheel 42. The universal wheel 42 is squeezed and fixed. Therefore, when the house is shrunk, it is prevented from affecting the bottom universal wheel and shaking, and the comfort of living in the house is improved.

[0022] Embodiment 3: Please refer to Figures 1 - 13 , the present invention provides a technical solution: on the basis of Embodiment 1, a door 5 is installed in the middle of the front of the machine base 1 in an openable and closable manner, and a contraction device 6 is movably installed on the top of the machine base 1, and the contraction device 6 is located on both sides of the inner cavity of the housing 2. The contraction device 6 is used to adjust the contraction state of the mobile house; The contraction device 6 includes a main board 61. Side strips 62 are fixedly installed in the middle of the front and back of the main board 61. Guide rails 63 are slidably connected to the tops of the side strips 62. A maintenance device 64 is movably installed on one side of the main board 61 away from the side strip 62. A plate 65 is movably installed at the bottom of the side wall of the main board 61. A cross bar 66 is inserted and installed in the middle of the inner cavity of the plate 65. A folding member 67 is fixedly installed at the bottom of the plate 65. A nail plate 68 passes through the folding member 67 and extends to the plate 65. When the nail plate 68 moves with the folding member 67, the plate 65 moves synchronously, and the folding member 67 is inserted and installed with the nail plate 68 at the bottom.

[0023] A main board 61 is movably installed on one side of the folding member 67 close to the side strip 62. The main board 61 is made of foam material. The cross bar 66 is a connected rubber layer. The side strip 62 slides along the inner cavity of the guide rail 63. The bottom end of the side strip 62 slides along the notch in the inner cavity of the housing 2. The nail plate 68 is connected to the plate 65 through the folding member 67. The maintenance device 64 is located above the plate 65 and on the side of the main board 61.

[0024] The maintenance device 64 further includes a vertical plate 641. A shaft rod 643 is movably installed at the top of the vertical plate 641. The main board 61 pushes the vertical plate 641, and the vertical plate 641 gradually displaces. The vertical plate 641 forms an extrusion on the shaft rod 643. The shaft rod 643 displaces to the innermost side of the guide rail 63. After the shaft rod 643 abuts against the innermost side of the guide rail 63, it continues to displace, and the shaft rod 643 passes through the inner cavity of the vertical plate 641. A torsion member 642 is movably installed on the inner surface of the vertical plate 641. An opening and closing plate 644 is embedded on one side of the torsion member 642 away from the vertical plate 641. A thin plate 645 is fixedly installed at the top end of the opening and closing plate 644. A wiping member 646 is movably installed on one side of the thin plate 645 away from the vertical plate 641. One end of the vertical plate 641 away from the main board 61 is movably connected to the opening and closing plate 644. The opening and closing plate 644 is in an arc shape structure. The wiping member 646 is made of rubber material. A notch corresponding to the vertical plate 641 is provided inside the vertical plate 641.

[0025] During use, first open the door 5, and then enter the inside of the housing 2. Chutes are provided on both sides of the front and back of the housing 2, and guide rails 63 are arranged inside the chutes. Use an external force to push the main board 61 to move. The main board 61 drives the side strip 62 to displace. The thin strip on the top end of the side strip 62 slides along the inner side of the guide rail 63, thereby ensuring the basic conditions for the rapid contraction of the device and paving the way for saving storage space for the mobile house.

[0026] When the interior needs to be shrunk, the main board 61 is pushed to move by external force, and the side strips 62 move synchronously with the main board 61. The side strips 62 slide along the inner cavity of the guide rail 63, and the bottom of the side strips 62 slide along the groove in the inner cavity of the shell 2. The guide rail 63 is convenient for auxiliary support of the maintenance device 64 and the side strips 62 to prevent the maintenance device 64 or the side strips 62 from being deformed and sagging due to long-term use. The main board 61 squeezes the folding piece 67, and the folding piece 67 is gradually squeezed and shrunk. The nail plate 68 penetrates the folding piece 67 and extends to the plate 65. The nail plate 68 is linked with the movement of the folding member 67, and the plate 65 moves synchronously, and the horizontal bar 66 is located between the several plates 65. The horizontal bar 66 is a rubber layer connected between the several plates 65. The several plates 65 are squeezed and shrunk in one place, and the horizontal bar 66 forms a folding tendency. Then, through the coordinated use of the folding member 67, the plate 65 and the horizontal bar 66, the device is guaranteed to have a rapid contraction function, thereby reserving the space inside the shell 2, and the adjustment is flexible and the disassembly is convenient. There are no unnecessary and cumbersome steps, which effectively saves the space occupied by the mobile house.

[0027] When the inner wall of the house needs to be cleaned, when the main board 61 and the side strip 62 slide along the inside of the guide rail 63, the main board 61 pushes the vertical plate 641, and the vertical plate 641 gradually moves. The vertical plate 641 squeezes the shaft rod 643, and the shaft rod 643 moves to the innermost side of the guide rail 63. The shaft rod 643 pushes the innermost side of the guide rail 63 and continues to move. The bending degree of the vertical plate 641 increases, and the vertical plate 641 is deformed to be supported outward. The vertical plate 641 squeezes the opening and closing plate 644, and the opening and closing plate 644 is deformed. The torsion member 642 buffers the tension of the opening and closing plate 644, and the opening and closing plate 644 pushes the thin plate 645 to move synchronously. The wiping member 646 moves with the displacement of the thin plate 645, and the thin plate 645 swings to wipe the inner wall of the mobile house, thereby improving the cleaning of the inner wall of the house, realizing the function of cleaning the house, and saving the labor intensity of manual cleaning.
