The protective lock handle is arranged at the upper end of the protective lock body. The lower cover is arranged at the lower end of the protective lock body. A clamping boss is arranged in the position, corresponding to the protective lock body, of the lower cover. Locating bosses are arranged on the two sides of the clamping boss. The lower end of the protectivelock body is provided with locating grooves matched with the locating bosses. A non-penetration cavity is formed in the protective lock body from bottom to top. Through the replaceable five-prevention lock protective cover, the service life of a lock is prolonged, and the dust accumulation prevention effect is good; the problems that a lock is poorer in reliability, is damaged easily and cannot be opened due to the phenomena of sand accumulation, rustiness and electrochemical corrosion in a lock body are avoided; the operation efficiency of operation and maintenance personnel is improved.

Description

technical field [0001] The invention relates to the technical field of hardware-related equipment, in particular to a replaceable protective cover for five-proof locks.
