Problems solved by technology

[0002] At present, lock door handles are divided into two types: left-opening and right-opening. Once the commonly used structure is assembled, the opening direction cannot be changed unless it is reassembled. During construction and installation, a corresponding number of left-opening and right-opening door handles must be prepared. , and no mistakes can be made during installation, otherwise it must be disassembled and reassembled or purchased to obtain a door handle with an accurate door opening direction, which adds trouble to the construction; there are also handles with reversing function, but their structure is more complicated or the operation is not easy convenient
[0003] Moreover, the current door lock bodies are basically directly installed inside the door body, or directly fixed on the panel. This lock body structure leads to very inconvenient installation, and it is necessary to destroy the panel or the door body when replacing the lock body, causing other problems. Components can no longer be used, resulting in waste

Abstract

The invention provides a door lock structure easy to replace. The door lock structure comprises a lining plate; a rotating shaft hole is formed in the middle of an upper side of the lining plate; a rotating shaft is arranged in the rotating shaft hole; a retainer ring is arranged on the rotating shaft; limiting blocks matched with the retainer ring are mounted on the lining plate on two sides of the retainer ring, respectively; the two limiting blocks are arranged symmetrically; a spring is connected to a lower side of the retainer ring; an upper end of the spring is connected to an upper positioning piece that is connected to the retainer ring; lower positioning pieces are arranged on the lower end and on both upper and lower sides of the upper positioning piece, respectively; the lower positioning pieces are connected to a fixed plate; and a mounting hole is formed in the lining plate. According to the door lock structure easy to replace, a lock body structure is mounted and fixed on the lining plate, such that a degree of modularization can be increased, and the mounting efficiency can be improved during mounting use or replacement; meanwhile, as a panel is separated from the lock body, the panel still can be used continuously when the lock body is replaced, and therefore, the cost of replacement is reduced.
