Foldable trailer coach

Abstract

The invention provides a foldable trailer coach which comprises a frame and a shingle arranged on the frame. The frame comprises a bottom frame, a top frame and at least four foldable columns, wherein each foldable column comprises an upper folding column, a lower folding column and a locking connecting devices which are arranged between the upper folding column and the top frame, between lower folding column and the bottom frame and between the upper folding column and the lower folding column. According to the trailer coach, the design of the locking connecting devices is adopted to achieve vertical folding of the trailer coach, the height of the trailer coach after being detached is only one fifth that of the trailer coach after the assembling, the trailer coach is convenient and fast to move and hoist, the logistics cost is greatly reduced, and the construction efficiency is effectively improved.

Description

technical field [0001] The invention relates to a folding activity room, in particular to a folding activity room with a locking connection device. Background technique [0002] In the process of my country's national economic development, prefabricated houses have been widely used. At present, there are many types of activity rooms and they are varied. Representative prefab houses mainly include the following types, namely, tent type, container type and one-time assembled color steel wall panel prefab houses. Although the tent-type mobile home is easy to assemble, disassemble and transport, the facilities are simple and the comfort is poor, it is difficult to meet the requirements of multiple layers, and the floor area is large; the logistics cost of the container-type mobile home is too high. The connection firmness is poor, and the middle layer is composed of two layers of bottom wall panels, so the manufacturing cost of the box is high; and the one-time assembled color...

Problems solved by technology

Although the tent-type mobile home is easy to assemble, disassemble and transport, the facilities are simple and the comfort is poor, it is difficult to meet the requirements of multiple layers, and the floor area is large; the logistics cost of the container-type mobile home is too high. The connection firmness is poor, and the middle layer is composed of two layers of bottom wall panels, so the manufacturing cost of the box is high; and the one-time assembled color steel wall panel activity room that belongs to the mainstream product of the activity room is basically assembled. The manufacturing mode and technology of permanent houses are faced with the defects of slow construction speed, many safety hazards, and high labor costs; during dismantling, the ground ceiling and hydropower work items are severely damaged, and other structural parts are greatly damaged, resulting in large material loss. It is not easy to turn around and use, and at the same time, it will cause a large amount of construction waste and increase the cost of environmental protection; in view of the above shortcomings, the present invention urgently needs to provide a new folding activity room
