Problems solved by technology

However, it is this design of free rotation that often causes the anti-rotation piece to shift when the user unlocks the lock (that is, to prevent the lock hole on the piece from being misaligned with the lock hole on the lock cylinder), and the direction of the lock hole of the anti-rotation piece Uncertain, so that every time the user opens the door, he needs to observe the direction of the anti-drilling piece, first insert the key and then adjust the direction of the anti-drilling piece to insert the key into the lock cylinder to unlock, which causes trouble and time-consuming for the user to unlock

Abstract

Disclosed is a mortise door lock of an adjustable explosion-proof cover. The mortise door lock of an adjustable explosion-proof cover comprises a lock cylinder arranged in a door sheet, a front face plate, a rear face plate and a handle, wherein the front face plate, the rear face plate and the handle are arranged outside the door sheet. The mortise door lock is characterized in that the lock cylinder is arranged in a lock hole in the door sheet; the outer end of the lock cylinder is sequentially covered with the explosion-proof cover and a protective cover; the protective cover is in screwed joint with a fixed plate arranged on the inner side of the door sheet to enable the door sheet to be clamped between the protective cover and the fixed plate; and a bolt height adjusting device capable of adjusting the opposite distance between the explosion-proof cover and the lock cylinder is arranged between the explosion-proof cover and the fixed plate or between the explosion-proof cover and the protective cover. The mortise door lock has the beneficial effects that the bolt adjusting device is utilized so that the opposite distance between the explosion-proof cover and the lock cylinder can be precisely adjusted, and the advantages of being convenient to adjust, large in size adjusting range and the like are achieved; the protective cover is arranged outside the explosion-proof cover, the lock cylinder and the explosion-proof cover are covered with the protective cover, and meanwhile the bottom of the explosion-proof cover is tightly combined with the door sheet; and the side wall of the explosion-proof cover is a slope, and the phenomenon that a burglar damages the protective cover in prying or clamping and other manners can be effectively avoided.

Description

technical field [0001] The invention relates to an anti-theft lock, in particular to a mortise lock with an adjustable explosion-proof cover. Background technique [0002] The door lock generally adopts the mortise door lock cylinder. In order to protect the mortise door lock cylinder, a protective device is often installed on the outside of the door. The protection device of the existing mortise door lock lock cylinder is generally an explosion-proof cover that is sleeved on the outer end of the lock cylinder. The explosion-proof cover is provided with a concave hole to accommodate the end of the mortise door lock lock cylinder. The depth from the inside of the explosion-proof cover to the concave hole is designed according to the highest height of the mortise door lock cylinder protruding from the door panel. Therefore, when the explosion-proof cover is matched with the mortise door lock cylinder of different specifications, it may not be completely consistent. , for the ...
