Embodiment Construction

[0012] The specific embodiment of the present invention will be described in further detail below through specific examples.

[0013] A lock guard such as figure 1 As shown, the protective device includes a fixed plate and a protective cover. The fixed plate is mainly used to fix the protective cover. The protective cover is rotatably connected with the fixed plate through a rotating shaft. The top of the protective cover is an arc surface. The two sides of the protective cover are fan-shaped surfaces, and the preferred fan-shaped surfaces can be a quarter of a circle. Nut holes or foam double-sided adhesive strips are arranged on the fixing plate. If the upper area of ​​the lock is relatively smooth, you can use foam double-sided adhesive strips to fix the fixing plate on the door. If the upper area of ​​the lock is not smooth and difficult to bond and fix with foam double-sided adhesive strips, you can use screws The hole fixes the fixing plate on the door, and the protecti...
