Description

Technical Field

[0001] The invention relates to the technical field of foldable houses, in particular to a foldable high-heat-insulation camping house. Background Art

[0002] Camping houses are places for outdoor workers to live, rest and work. In order to facilitate transportation, a variety of folding camping houses have been developed. Existing folding camping houses mainly have two ways: folding to the bottom plate and folding to the middle. The bottom plate of the camping house folding to the bottom is limited by the width of the transport vehicle and is relatively narrow. In addition, multiple camping houses will be stacked during transportation, which is easy to damage the camping house. The camping house folding to the middle can overcome the above-mentioned disadvantages of the camping house folding to the bottom. For example, the Chinese invention patent with patent number "ZL201610890606.6" proposes a fully automatic intelligent deformation camping house.

[0003] However, the existing foldable camping houses still have some disadvantages. For example, the wall and roof of the camping house cannot be directly and quickly connected, and a large number of connectors are required, which makes the unfolding and folding operations of the camping house complicated. Another example is that the gap between the wall and the roof is large after being connected by connectors, which is not conducive to heat preservation. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a foldable high-insulation camping house that is upright and can be transported side by side without being stacked and crushed. The unfolded width is not limited by the transport vehicle, and the roof and side walls can be directly connected without the need for additional connecting parts.

[0005] The foldable high-insulation camping house of the present invention comprises a steel structure frame, a front bottom, a front gable, a front top, a side top, a side bottom, a front wall and a side gable; the front bottom is horizontally installed at the bottom of the steel structure frame, the front top is horizontally installed at the top of the steel structure frame, two front gables are vertically installed on both sides of the steel structure frame, two side tops are rotatably installed on both sides of the front top to form a roof, two side bottoms are rotatably installed on both sides of the front bottom to form a floor, two front walls are rotatably connected to the two side bottoms to form side walls, and a plurality of side gables are rotatably connected to the two sides of the two front gables to form gables, a supporting structure is provided at the edge overlap of the two front walls and the two side tops, the supporting structure guides the upper ends of the two front walls outward, a limiting structure is provided on the outer side of the edge overlap of the two front walls and the two side tops, the limiting structure is arranged along the contact edge of the two front walls and the two side tops, and the limiting structure The upper ends of the two front walls are hooked from the outside; when the foldable high-insulation camping house is unfolded, the two side roofs are unfolded, the two side bottoms are unfolded outward to form a floor, and the two front walls are erected to support the outer edges of the two side roofs, so that the two front walls are connected to the supporting structures of the two side roofs, and the two front walls are connected to the limiting structures of the two side roofs. The guiding effect of the supporting structure makes the two front walls tilt toward the outside of the foldable camping house, and the limiting structure hooks the two front walls from the outside, so that the limiting structure is pressed tightly, the connection is more stable, and the wall is prevented from tipping over, and a direct and quick connection between the wall and the roof is achieved, the use of connecting parts is reduced, and the unfolding and folding operations of the camping house are simplified. The limiting structure arranged along the contact edges of the two front walls and the two side roofs makes the wall and the roof connected as a whole. After being pressed by the guidance of the supporting structure, the gap at the connection is small, which is conducive to heat preservation.

[0006] Preferably, the expansion steps are:

[0007] 1. Expand the two side tops upward to form inclined side tops;

[0008] 2. Expand the two side bottoms downwards and lay them flat with the main bottom to form the floor;

[0009] 3. Erect the two front walls and connect the upper edges of the two front walls to the outer edges of the two side roofs respectively;

[0010] Fourth, the multiple side gables are rotated outward and spread out, and the edges of the multiple side gables are overlapped with the edges of the two side bottoms, the two front walls and the two side tops;
