Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, in particular to a sliding cover lock for a casement screen window. Background Art
[0002] The installation methods of screen windows are generally divided into invisible screen windows and casement screen windows. The casement screen window fixes the frame with the screen mesh on the window frame, and the frame is hinged to the window frame. The casement screen window has the advantages of long service life, low cost, and easy cleaning. For outward-opening windows, since the screen window is located inside the window, when using a fixed screen window, an opening for accommodating the window handle needs to be provided on the screen window. To prevent mosquitoes from entering the room through this opening when the window is opened, a sliding cover lock is generally installed at the opening. When the window is opened, the sliding cover of the sliding cover lock is slid down to close the opening.
[0003] Most of the existing sliding cover locks for casement screen windows do not have the function of firmly locking the screen window after closing the sliding cover, resulting in poor safety of the screen window. There may be safety accidents due to children's accidental operation of opening the screen window. Therefore, there is an urgent need for a sliding cover lock for casement screen windows that can be further improved and has different locking methods according to different needs. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems existing in the prior art.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A sliding cover lock for a casement screen window, comprising: a lock body cover plate and a lock body bottom cover. One end of the bottom of the lock body cover plate fixes a password dial fixing seat through a card slot. A password dial operation hole is opened on one side of the surface of the lock body cover plate. A slot for the second fork to slide is opened on the other side of the surface of the lock body cover plate. A first fork is embedded at the bottom of the password dial fixing seat. The first fork is embedded and installed with a password dial through a hole opened. A key dial is arranged at the center inside the password dial. A spring is fixed to the password dial fixing seat. One end of the spring is fixed with a ball. The first fork is connected to the bottom cover of the password dial fixing seat through the spring and the ball. One end of the bottom of the key dial is fixed in a groove opened on the bottom cover of the password dial fixing seat.
[0006] As a preferred implementation manner, a sliding cover seat is fixed through a fixing pin in a chute at one end of the bottom of the lock body cover plate. A rubber card is arranged on the sliding cover seat. An active sliding cover is arranged in the chute formed by the sliding cover seat and the lock body cover plate.
[0007] As a preferred implementation manner, one end of the active sliding cover is fixed with a second fork. One end of the active sliding cover is fixed with a clamping screw. The active sliding cover is clamped to the bottom cover of the password dial fixing seat through the clamping screw.
[0008] As a preferred implementation, a latch is provided on the first shift fork, and a V-shaped latching groove corresponding to the latch is provided at one end of the bottom of the code disk.
