Description

Simple activity room bracket structure supported by folding rods

technical field

The invention relates to a bracket structure of a simple movable room, in particular to a bracket structure of a simple movable room supported by folding rods supporting each other.

Background technique

Present simple prefabricated house is that hinged rods are deployed as a support, and hard plates or soft tarpaulins are fixed around the rods to form the front, rear, left, and right walls and roof of the prefab house. For example, in ZL200710037562.3 "Folding Prefab House" and ZL201020299363.7 "Rotatable Quick-installation Unit Prefab House", it is characterized by the shape of the herringbone slope roof and the vertical rod support of the four walls. Hinged, detached and fixed connections form the folding and unfolding functions. This type of structure is limited by the shape characteristics and structural support of the roof and four walls, the number of rods used is large, the wall is thick, the weight is heavy, the installation is not easy, the shape is single, and the expansion space is small. It is not suitable for rapid application in outdoor camping and activity places; in ZL201120177237.9 "A Double Rod Structure for Improving the Stability of Tent Support Rods", although the tent-type bracket described is light in weight, it has complex structure and stable support Poor performance, easy to damage, high cost, small use area, low space and other shortcomings. These current situations show that there is a certain waste in the shape, material, structure and space resource utilization of the mobile home.
