Description

Door lock convenient for inclined bolt reversing Technical Field The invention relates to a door lock basin convenient for inclined tongue reversing. Background In the installation and the use process of the door lock, as the door body has two different opening directions of left opening door and right opening door, and the installation position needs to be matched with the left side and the right side of the door body, the door lock is prevented from being independently designed and produced aiming at different door directions for improving the universality and the suitability of the lockset, and the inclined tongue reversing function becomes one of the core basic functions of the door lock product. At present, the inclined tongue reversing structure forms of the existing door lock are different, but the technical defects of complicated operation, insufficient reliability and the like generally exist, and the high-efficiency requirement of on-site construction and installation and the stability requirement of long-term use are difficult to meet. The traditional structure has the advantages that the reversing piece naturally falls down to realize reversing by disassembling the lock panel and overturning the lock body, the operation steps are complex, time and labor are consumed, the surface of the lock is scratched and internal transmission parts are damaged easily in the disassembling process, and the assembling precision and the service life of the lock are reduced; in addition, some structures adopt an external reversing design, and the inclined tongue is pushed or stirred to be ejected for rotary reversing, so that the structure does not need to detach the lock body, but the risk of unexpected ejection of the inclined tongue and blocking in the reversing process exists, and the positioning stability is poor after reversing is finished, so that the inclined tongue is easy to deviate due to vibration and abrasion after long-term use, and the normal function of the door lock is influenced. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the door lock convenient for the inclined tongue reversing, which has the advantages of simple structure, convenient reversing operation, reliable and stable use and good use effect. In order to achieve the above purpose, the invention provides a door lock convenient for reversing a latch, which comprises a lock shell, wherein a latch hole is formed in the lock shell, the latch is slidably arranged in the latch hole, a connecting rod is rotatably matched on the latch, the connecting rod is in plug-in connection with the lock shell, an abutting boss is arranged on the peripheral wall of the connecting rod, a latch spring is abutted between the abutting boss and the lock shell, the latch spring is sleeved on the connecting rod, a latch groove is formed in the side wall of the latch hole, a sliding step is arranged in the latch groove, a step surface of the sliding step is combined with one side wall of the latch groove to form a first sliding part, the side wall of the sliding step, the bottom surface of the latch groove and the other edge of the latch groove are combined to form a second sliding part, a disassembling opening for the latch is formed in the position corresponding to the second sliding part on the lock shell, one end of the sliding step far away from the disassembling opening is provided with a notch groove, the lengths of the first sliding part and the second sliding part are longer than the latch exposed on the connecting rod, the length of the latch spring is arranged in the outer side wall of the lock shell, the sliding step surface of the sliding part is provided with a sliding groove, one end face is arranged in the sliding body corresponding to the first sliding part is arranged in the sliding body, the sliding part is provided with a sliding groove is arranged in the sliding groove, and the sliding groove is movably corresponding to the other end face of the sliding body, and the sliding part is provided with a sliding body. The sliding door lock has the advantages that the sliding tongue slides in the lock groove during normal use, at the moment, the sliding tongue continuously collides in the lock groove due to the fact that the length of the sliding tongue exposed out of the lock shell is limited, the locking tongue only slides on the first sliding part during opening and closing of the door and does not reach the position of the notch groove, so that the second sliding part cannot be accessed, accidents caused by the fact that the structure is in normal operation are avoided, when the sliding tongue is required to perform reversing actions, the sliding tongue is pressed in further by hand, the movable shaft body on the sliding tongue enters the notch groove along the first sliding part and then reaches the second sliding groove, at the moment, the position of the movable shaft body also slides in the movable gr
