Supporting frame and rotation limiting device
The invention relates to a supporting frame and a rotation limiting device. The device can be used for a supporting frame of a baby crib bag, a pet bag, a tent, a mosquito net and the like, and the supporting frame is used for supporting the mosquito net or the tent, and can be folded or unfolded for use. According to the technical scheme,the rotation limiting device is connected to two main spokes, auxiliary spokes are installed on the main spokes, the auxiliary spokes and the main spokes are connected through a rotating shaft, and the main spokes and the space between the auxiliary spokes and the main spokes are directly connected through one rotating shaft. The main spokes and the space between the auxiliary spokes and the main spokes are directly connected through one rotating shaft, so that the structure is more stable, and operation is easier; the two main spokes are connected by using the rotation limiting device, and the unfolding state can be fixed in multiple angles, so that the main spokes are in a semi-unfolding state or a full-unfolding state; and particularly, an elastic piece of an elliptical ring structure is adopted, the deformation direction of the elliptical ring is perpendicular to the rotating axis, and the defects that the rotary joint is expanded and loses the limiting effect due to the fact that beveling force parallel to the rotating shaft is generated are perfectly overcome.
本发明涉及一种支撑框架及旋转限位装置，可用于婴儿床包、宠物包、帐篷、蚊帐等的支撑架，用于支撑蚊帐或帐篷，可以折叠或展开使用，本发明的技术方案是：采用旋转限位装置连接两个主辐条，副辐条安装在主辐条上，采用旋转轴连接副辐条和主辐条，主辐条之间及副辐条与主辐条之间只采用一个旋转轴直接连接，由于主辐条之间及副辐条与主辐条之间只采用一个旋转轴直接连接，结构更稳定，操作更简单，由于采用旋转限位装置连接两个主辐条，可以在多个角度固定展开状态，使其处于半展开或全展开状态，尤其是，采用椭圆环结构弹片，椭圆环变形方向与旋转轴线垂直，完美解决产生与旋转轴平行的斜切力，使得旋转接头被撑开，失去限位作用的缺陷。
