图 5和图 9表示了各杆件组绕图 6所示铰接副轴心展开后由限位销钉 10限定在设定位置 的示意图。 其中， 第一主支撑梁 1通过设置在其上的一个限位销钉 10对下部斜撑杆 4限位； 并通过设置在其上的另一个限位销钉 10对上部斜撑杆 2限位。
图 10表示了上部斜撑杆 2与上部平撑杆 3上设置的限位销钉 10相互作用， 保证上部平 撑杆处于水平位置。
图 11表示了下部斜撑杆 4上设置限位销钉 10保证下部斜撑杆 4与底部平撑杆 5之间获 得要求夹角的示意图。
本发明的装配和安装过程为：
首先， 将图 7、 图 8所示的三根第一主支撑梁 1 、 一根第二主支撑梁 11所在的折叠杆件组展 开;按图 4所示，先使相邻第一、第二根第一主支撑梁 1 呈 90° 在窄榫口扣位配合，得到" 型； 再将第二、 第三根第一主支撑梁 1 在窄榫口扣位呈 90° 配合得到 "i "型； 接着将杆 件组的一根第二主支撑梁 11 上两个锁紧块 12的锁紧块紧固螺钉 9拧松， 绕铰链打开， 使一 根第二主支撑梁 1的宽榫口压入第一、 第三根的第一主支撑梁 1窄榫口处， 得到 "井"型； 最后合上锁紧块 12， 拧紧两处的各两个锁紧块紧固螺钉 9， 将榫口全部压紧， 形成三根第一 主支撑梁 1和一根第二主支撑梁 11所在杆件组能相互支撑的稳定 "井"型框架。
然后， 将 "井"型框架上的三根第一主支撑梁 1和一根第二主支撑梁 11所在杆件组的四 根底部平撑杆 5与四根下部斜撑杆 4按图 11所示位置展开， 分别用限位销钉 10限定角度。
接着， 将 "井"型框架上的三根第一主支撑梁 1和一根第二主支撑梁 11所在杆件组的四 根下部斜撑杆 4与主支撑梁 1和主支撑梁 11按图 5、 图 9所示， 采用四个限位销钉 10分别 限定其与三根第一主支撑梁 1和一根第二主支撑梁 11的角度和位置。
第四， 先将完成上述装配的支架结构中的四个底部平撑杆 5放在地面上， 再将 "井"型 框架上的三根第一主支撑梁 1和一根第二主支撑梁 11所在杆件组的上部平撑杆 3和上部斜撑 杆 2按图 10所示， 采用四个限位销钉 10， 限定其角度。
最后， 将 "井"型框架上的三根第一主支撑梁 1和一根第二主支撑梁 11所在杆件组的上 部斜撑杆 2与主支撑梁 1和主支撑梁 11按图 5、 图 9所示， 采用四个限位销钉 10分别限定 上部斜撑杆 2与三根第一主支撑梁 1和一根第二主支撑梁 11的角度和位置。
本发明的简易活动房支架折叠收纳过程， 按上述安装过程反向操作。
首先，将支架结构上的上部斜撑杆 2与三根第一主支撑梁 1和一根第二主支撑梁 11之间 的四个限位销钉 10拆下。
然后， 将上部平撑杆 3和上部斜撑杆 2之间的四个限位销钉拆下。 翻转支架结构， 使底 部平撑杆 5底面朝上， 主支撑梁 1和主支撑梁 11构成的 "井"型框架坐落于地面。
接着， 将下部斜撑杆 4与主支撑梁 1和主支撑梁 11之间的四个限位销钉 10拆下。 第四， 将底部平撑杆 5与四根下部斜撑杆 4之间的四个限位销钉 10拆下。
第五， 拧松锁紧块紧固螺钉 9， 锁紧块 12绕铰链打开， 依次取出一根第二主支撑梁杆件 组和三根第一主支撑梁杆件组。
最后将三根第一主支撑梁杆件组和一根第二主支撑梁杆件组分别按照图 7和图 8的示意 图进行折叠收纳。
