Novel door lock

Abstract

The invention discloses a novel door lock, and belongs to the technical field of electrical mechanical interlocking devices. A door sheet is internally provided with four interlocking board assemblies, fixed bending plates are arranged on the interlocking board assemblies and welded to the door sheet, a lifting door lock body is installed on the door sheet, fixed sliding groove studs are arrangedbelow the lifting door lock body, the fixed sliding groove studs are in sliding connection with the interlocking board assemblies, and a side plate is arranged on the lower portion of the door sheet;an improved lifting lock device has a padlock measurement function, a lock cover plate is additionally arranged on the upper portion of the lock, a seal plate is additionally arranged on the side faceto block a lock tongue, on the condition that no dedicated key exists, the lock cannot be opened, and the five-prevention requirement is achieved; the lock is quick in door opening and closing, convenience is brought to a user better, the user can open the door sheet at first time conveniently in the maintenance process, and the improved door lock cannot lead to the phenomenon that the left-rightposition of a door lock hole is deviated, and the production efficiency is lowered; by means of the lock, the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a novel door lock, which belongs to the technical field of electromechanical interlocking devices. Background technique [0002] The schematic diagram of the existing door lock is as follows: Figure 1-2 As shown: the steps to open the door are as follows: first get the special external hexagonal wrench a, insert the wrench into the door lock b, and turn it counterclockwise until the door lock screw turns outside the screw thread, then the door panel c can be opened. [0003] The door closing procedure is as follows: After closing the door panel, get a special external hexagonal wrench, insert the wrench into the door lock b, and turn it clockwise until the door lock screw turns inside the screw thread, and the door panel c is considered to close the door until the screw can no longer be screwed. [0004] 3 to 4 door locks b are required to install the lock on each door panel c. During the installation, when the main frame and ...

AI Technical Summary

Problems solved by technology

[0004] 3 to 4 door locks b are required to install the lock on each door panel c. During the installation, when the main frame and door panel c deviate, the door lock screw is deviated, and the door panel c is closed to the door lock screw at the side panel d. The left and right deviation of the screw hole position is large and it is not easy to fix it, which will reduce the production efficiency of the production workers

Every time the user needs maintenance and repair, the user needs to use the hex wrench to turn counterclockwise / clockwise to twist the lock when opening and closing the door, which brings inconvenience to the user, and the disadvantage is that it is very time-consuming
