所述衬套簧座连杆50上设有容纳折叠状态自锁弹簧组件的连接容槽51，自锁弹簧组件70的一端伸入到第二容槽41内通过第八铰轴108与第二容槽41的侧壁铰接，自锁弹簧组件70的另一端伸入到连接容槽51内通过第九铰轴109与连接容槽51的侧壁铰接，在折叠时，自锁弹簧组件70围绕第九铰轴109向靠近力臂60方向转动，折叠收拢完成后，自锁弹簧组件70容纳在衬套簧座连杆50的连接容槽51内。所述衬套簧座连杆50包括两个连杆以及用于连接两个连杆的连接铆钉，连接容槽处于两个连杆之间。
值得注意的是，门板固定座10、柜体固定座20、摇臂30、轴弹簧座连杆40、衬套簧座连杆50以及力臂60组成两个四边形结构，第一个四边形结构由柜体固定 座上的第一铰轴101与第六铰轴106之间的间距、摇臂30上第一铰轴101与第五铰轴105之间的间距、衬套簧座连杆上第五铰轴105与第七铰轴107之间的间距组成；第二个四边形结构由摇臂30上第五铰轴105与第二铰轴102之间间距、轴弹簧座连杆40、门板固定座10以及衬套簧座连杆50组成。在展开时，门板固定座10与柜体固定座20张开时，两个四边形结构张开，摇臂30以第一铰轴101为支点向远离柜体固定座20方向转动，力臂60以第六铰轴为支点向远离柜体固定座20方向转动，第一个四边形内第一铰轴101与第七铰轴107的间距达到最大，第二四边形内第三铰轴103与第五铰轴105的间距达到最大，门板固定座10与柜体固定座20之间形成间距，门体打开角度范围为0～115度；而在折叠收拢时，两个四边形结构折叠收拢，摇臂30以第一铰轴101为支点向靠近柜体固定座20方向转动，力臂60以第六铰轴为支点向靠近柜体固定座20方向转动，第一个四边形内第六铰轴106与第五铰轴105的间距达到最大，第二四边形内第二铰轴102与第四铰轴104的间距达到最大，各臂体收纳在门板固定座10与柜体固定座20之间。
如图6所示，所述自锁弹簧组件70包括轴弹簧座701、与轴弹簧座701配合的衬套弹簧座702以及处于轴弹簧座701和衬套弹簧座702之间的弹簧703，轴弹簧座701通过第八铰轴108与轴弹簧座连杆40铰接，衬套弹簧座702通过第九铰轴109与衬套弹簧座连杆50铰接。所述自锁弹簧组件70两端分别铰接在轴弹簧座连杆40和衬套簧座连杆50之间，对轴弹簧座连杆40和衬套簧座连杆50施加一个弹性推力，在本发明开启于接近展开最大角度状态时，门板固定座10与衬套簧座连杆50夹角已接近180度，轴弹簧座连杆40受自锁弹簧组件70的弹性推力作用下，以第三铰轴103为支点顺时针旋转，轴弹簧座连杆40与门板固定座10夹角继续减小；也即是门板固定座10、轴弹簧座连杆40、摇臂30及衬套簧座连杆50铰接构成的四边形在自锁弹簧组件70的作用下继续朝本发明展开状态形变，第三铰轴103和第五铰轴105之间距离继续扩大，固定连接在门板固定座10上的门体从而也就获得一个开启自锁弹性作用力。
参照图7中所示，同理相反，在本发明折叠收拢接近最小角度状态时，门板固定座10、轴弹簧座连杆40、摇臂30及衬套簧座连杆50铰接构成的四边形在自锁弹簧组件70的作用下继续朝本发明折收拢状态形变，第二铰轴102和第四铰轴10 4之间距离继续扩大，固定连接在门板固定座10上的门体从而也就获得一个关闭自锁弹性作用力。
所述门板固定座10的一侧设有用于安装在门体的第一安装板12，通过第一安装板12安装在门体上；所述柜体固定座20的一侧设有用于安装在柜体一侧的第二安装板23，通过第二安装板23安装在柜体上。
综上所述，本发明的技术方案可以充分有效的实现上述发明目的，且本发明的结构及功能原理都已经在实施例中得到充分的验证，能达到预期的功效及目的，在不背离本发明的原理和实质的前提下，可以对发明的实施例做出多种变更或修改。因此，本发明包括一切在专利申请范围中所提到范围内的所有替换内容，任何在本发明申请专利范围内所作的等效变化，皆属本案申请的专利范围之内。
