Rotation limiting device and door/window
The invention relates to the technical field of doors and windows, and particularly discloses a rotation limiting device and a door/window.The rotation limiting device comprises a fixed base, a rotating groove is formed in the fixed base, a follower is rotationally arranged in the rotating groove, and a limiting groove rail is arranged on the inner wall of the rotating groove; the limiting groove rail is provided with a locking clamping groove which is concavely arranged in the direction away from the follower and a pushing part which is convexly arranged in the direction close to the follower, a guiding inclined wall is arranged on the side, close to the pushing part, of the locking clamping groove, and the follower is provided with a movable groove with an opening facing the limiting groove rail and a groove formed in a closed loop mode. A locking piece capable of stretching out and drawing back inside and outside the movable groove is arranged in the movable groove, the locking piece is connected with an elastic piece used for driving the locking piece to move in the direction close to the limiting groove rail and a traction piece used for limiting the moving stroke of the locking piece, the traction piece comprises a connecting end and a sliding end, the connecting end is connected with the locking piece, and the sliding end is connected with the locking piece. The sliding end slides in the groove, and the groove is provided with at least two positioning points used for positioning the locking piece at different stroke positions. The rotation limiting device can be fixed to a certain angle position after the rotation limiting object rotates and can be unfixed along with the rotation stroke when the rotation limiting object reversely rotates and resets, the whole device is simple, an electric control device is not needed, and the rotation limiting device can be installed at the position where a rotating shaft piece of the rotation limiting object is located; normal use of a rotation limiting object cannot be interfered, and the overall appearance is simpler and more attractive.
本发明涉及涉及门窗技术领域，具体公开一种转动限位装置及门/窗，转动限位装置包括固定基座，固定基座上设有转动槽，转动槽内转动设有随动件，转动槽的内壁设有限位槽轨，限位槽轨设有朝远离随动件的方向凹陷设置的锁合卡槽及朝靠近随动件的方向凸起设置的推顶部，锁合卡槽靠近推顶部的一侧设有导向斜壁，随动件设有开口朝向限位槽轨的活动槽以及呈闭合回路设置的沟槽，活动槽内设有可伸缩于活动槽内外的锁合件，锁合件连接有用于带动锁合件沿靠近限位槽轨的方向移动的弹性件，以及用于对锁合件的移动行程进行限位的牵引件，牵引件包括连接端及滑行端，连接端与锁合件相连接，滑行端滑行于沟槽内，沟槽设有至少两个用于将锁合件定位在不同行程位置的定位点。本发明的转动限位装置能够在转动限位对象转动后固定在某一角度位置，并且能够在转动限位对象反向转动复位时随转动行程解除固定，整体装置简单，无需电控装置，可安装于转动限位对象的转轴件所在位置，不会对转动限位对象的正常使用造成干涉，整体外观更简洁、美观。
