Anti-theft device for opening and closing door
The invention relates to a door opening and closing anti-theft device which comprises a shell installed in a door pocket, a limiting piece is slidably connected into the shell and is in an L shape, the vertical section of the limiting piece is slidably inserted into the shell, the horizontal section of the limiting piece is located outside the shell, a through hole is formed in the outer end face of the shell, and a through hole is formed in the outer end face of the through hole. The bottom of the through hole is provided with a limiting protrusion, the vertical section of the limiting piece is provided with a straight sliding groove and an arc-shaped sliding groove, the length direction of the straight sliding groove is consistent with the axis direction of the through hole, the arc-shaped sliding groove is communicated with the straight sliding groove, the arc-shaped sliding groove is formed in the outer side of the straight sliding groove, and the limiting protrusion is clamped in the straight sliding groove or the arc-shaped sliding groove in a sliding mode. The device only needs to be fixedly installed in the door pocket, then the rotary limiting piece is pulled, and the position of the limiting protruding shaft in the arc-shaped sliding groove or the straight sliding groove is changed, so that the door opening limiting effect can be achieved, the installation mode is simple, cost is low, and the device is suitable for industrial production and has high practicability.
本发明涉及一种房门启闭防盗装置，包括有安装在门套内的壳体，壳体内滑动连接有限位件，所述限位件呈L型设置，限位件的竖直段滑动插接在壳体内，限位件的水平段位于壳体外设置，壳体外端面上开设有贯穿孔，贯穿孔底部设置有限位凸起，限位件的竖直段上分别开设有直滑槽与弧形滑槽，直滑槽的长度方向与贯穿孔的轴线方向一致，弧形滑槽与直滑槽接通，且弧形滑槽位于直滑槽的外侧设置，所述限位凸起滑动卡接在直滑槽或弧形滑槽内设置，该装置仅仅需要固定安装在门套内，再通过拉动旋转限位件，通过限位凸轴在弧形滑槽或直滑槽内的位置改变，即可完成对于房门开启的限位作用，安装方式简单且成本低廉，适用于工业生产中，具有很强的实用性。
