Description

A lock body and sliding door and window

technical field

The invention relates to a lock body, in particular to a lock body for flat opening sliding doors and windows and sliding doors and windows.

Background technique

In daily life, the use of sliding doors and windows has become very common. Sliding doors and windows are a necessary decorative door and window for modern home decoration. Because the sliding method is used to open the door, it can greatly improve the indoor environment compared with ordinary rotary switch doors and windows. The utilization rate of space, but because the general sliding doors and windows cannot be fully opened, and the channel position is limited, people hope to combine the sliding doors and windows with the casement revolving doors and windows, which can realize both the sliding half-opening doors and windows and the casement opening. Rotating fully open doors and windows. When realizing both sliding and sliding doors and windows, the sliding track of sliding doors and windows includes two parts: one part is a fixed track fixed on the upper part of the door and window frame, and the other part is a moving track fixed on the top of the fixed door and window frame. With the help of the fixed track sliding to the moving track, it can be rotated after overlapping with the fixed door and window. This requires that a special lock body must be designed on the fixed track and the moving track, so that the sliding doors and windows can smoothly slide from the fixed track to the moving track.

In order to solve the above problems, there is such a design in the prior art: patent application number 2016102318145, application publication number CN105715132A, application publication date June 29, 2016, invention name "a lock body and sliding doors and windows". The specific content of the prior art is: a lock body, comprising a lock catch and a lock catch fitting portion, the lock catch includes a lock tongue, a lock catch body and a first pulley hole of the lock body, and the lock tongue extends into the lock body. The first pulley hole of the lock body, the lock fitting part includes a blocking sheet and the second pulley hole of the lock body, the blocking sheet is used to compress and block the lock tongue, the two sides of the lock tongue are grooves, the The end of the groove away from the first pulley hole of the lock body is provided with a first buckle, the lock body is provided with a protrusion, the groove is matched with the protrusion, and the first buckle is matched with the protrusion. The protrusions match. When the present invention realizes the doors and windows that can be pushed and pulled and can be opened horizontally, the lock tongue on the lock can block the pulleys of the sliding doors and windows when the doors and windows are opened horizontally, so as to prevent the sliding doors and windows from sliding out of the track. At the same time, when the doors and windows are closed, the lock After the tongue is compressed from bottom to top, the slideway can be released, so that the pulley of the sliding door and window can be pushed and pulled through the track to achieve the purpose of closing the door and window. The defect of the prior art is that the lock tongue can only be compressed horizontally, and a blocking piece must be used in conjunction with it. Before hitting the blocking piece, when the lock tongue is high, it is extremely easy for the lock tongue to touch the end of the lock catch first, which will affect the closing of the door panel. In addition, the lock body and the sliding door and window of the prior art can only be used for a single movable door, and a return spring must be used, so the application environment is limited and the structure is complicated.
