According to the scheme, the door handle and the lock tongue box are designed into an integrated form, the lock tongue box is fixed on the sliding door, the lock head is fixed on the door frame, and the lock tongue box is hidden on the door handle. Although the technical scheme meets the general use requirement of the sliding door, the sliding door has some problems and defects in practical application, and is specifically shown as follows: firstly, the lock body is arranged on the push door and the pull, and the door handle is directly vertical and protrudes out of the frame of the push door leaf, so that limbs are easy to collide with corners of the handle to cause injury in the process of entering and exiting. And, the door handle is rectangular structural design, makes its corner position all comparatively sharp-pointed, when people's limbs touch on the door handle, receives the injury more easily. Therefore, the sliding door lock with the structure has a certain safety default because of the unscientific structural design, and cannot be comprehensively popularized and applied, especially cannot be applied to public places with more people in and out, or more public safety disputes are easily caused. Secondly, because the whole door handle is long structural design, no special part for people to grasp when opening and closing the door is reserved or designed on the door handle, people can not conveniently find the grasping position when opening and closing the door, and the practicality and the use convenience of the door handle are quite poor. Thirdly, because the tapered end and the door handle are designed to be of a split structure, when the door handle is applied, the door handle must be installed on the push-pull door leaf, and the tapered end must be installed on the door frame. The novel door lock has the advantages that the limitation in application is large, the application range is narrow, the whole set of lock product is large in size, the structure is not compact enough, the novel door lock can be only used for door leaves and door frames with wide frames, and the novel door lock cannot be applied to narrow-frame sliding door products popular in the current market, and is poor in applicability and narrow in application range. Therefore, in view of the foregoing various shortcomings of the existing sliding door locks, it is necessary to redevelop and design the existing sliding door locks, so that the existing sliding door locks can better keep pace with the development pace of the sliding door, and meet the application requirements of modern sliding doors.
