Description

Screen lock structure

The invention relates to a screen window lock structure, in particular to a screen window lock structure capable of fixing the relative position of the screen window and the fixed window frame.

Existing horizontal-pull windows are mainly provided with two movable window frames whose main body is glass in a fixed window frame. Therefore, when the two movable window frames are in the open state, the screen window is located at the opening, so it can prevent dust, mosquitoes, insects, etc. from entering the room when the indoor and outdoor air is circulated.

Generally speaking, there is an engaging structure between the track on the fixed window frame for installing the screen window and the frame of the screen window, so that the screen window can move along the track of the fixed window frame, but cannot be arbitrarily removed from the frame. The fixed window frame is removed, and this design can not only prevent theft, but also prevent the screen window from falling due to improper external force such as strong wind, and prevent accidents from occurring.

However, although the screen window will not easily fall from the fixed window frame, the screen window and the fixed window frame do not have a structure that can be combined and positioned with each other, so that the screen window can still move along the track of the fixed window frame. Therefore, On windy days such as typhoon days, the screen window will be swayed laterally by strong winds, or even moved, so as to collide with the fixed window frame or the moving window frame. In this way, in addition to generating noise, the screen window will also damaged by collision.

In view of the aforementioned problems in the prior art, the purpose of the present invention is to provide a screen window lock structure, which can fix the relative position of the screen window and the fixed window frame, and prevent the screen window from shaking or moving.

In order to achieve the above-mentioned creative purpose, the technical means adopted by the present invention is to make a screen window lock structure including: a fixed window frame, which has a side plate, and the inner side of the side plate is provided with at least one limiting recess; a screen window, which It is installed in the fixed window frame and has a screen frame, and at least one installation slot is arranged on the screen frame; The locking element includes a positioning seat and a locking piece, the positioning seat is fixed in the installation groove of the screen window, and the opposite ends of the positioning seat are respectively a retracted end and a protruding end, and the protruding end faces toward The side plate of the fixed window frame, the positioning seat has a guide piece, the guide piece extends obliquely from the protruding end of the positioning seat toward the side guide groove of the fixed window frame, and the locking member is elastic and movable Installed in the positioning seat, the locking piece has a limiting tab, the limiting protruding piece is extended and formed at one end of the locking member facing the protruding end of the positioning seat, and the locking member can be driven to The limiting protruding piece is selectively received in the positioning seat, protruding from the side guide groove of the side plate of the fixed window frame or protruding into the limiting recess of the side plate of the fixed window frame.

In the lock structure of the screen window, the positioning seat can have two side frames arranged at intervals, and the two ends of each side frame extend toward the retracted end and the protruding end of the positioning seat respectively, and each side frame A first positioning part, a second positioning part and a third positioning part are arranged in sequence from the retracting end to the protruding end of the lock; On both sides, the two positioning portions can selectively engage and position with the two first positioning portions, the two second positioning portions or the two third positioning portions of the positioning base, respectively.

In the lock structure of the screen window, the first positioning part, the second positioning part and the third positioning part of the positioning seat can all be formed as concave parts, and the positioning part of the locking piece can be formed as a convex part.

In the lock structure of the screen window, the lock member can have a toggle rod, and the toggle rod protrudes out of the positioning seat.

In the lock structure of the screen window, the inner side of the side plate of the fixed window frame can be concavely formed with a side guide groove, and the bottom of the side guide groove is further formed with the at least one limit concave part, and each limit concave part can be formed. Pass through the side panel of the fixed window frame.

In the screen window locking structure, at least one limiting piece can be fixed on the inner side of the side plate of the fixed window frame, and the limiting recess is formed on each limiting piece.

With the above-mentioned design, when the limiting tab of the locking element of the locking element is received in the positioning seat, the user can remove the screen window from the fixed window frame; when the locking element is When the limiting tabs of the locking pieces protrude into the side guide grooves of the side plates of the fixed window frame, the screen window can move along the guide rails set on the fixed window frame, but cannot be moved from the fixed window frame When the limit tab of the lock member of the lock assembly protrudes into the limit recess of the side plate of the fixed window frame, the screen window not only cannot be removed from the fixed window frame, but also cannot be removed along the fixed window frame. The guide rail provided on the fixed window frame moves. Therefore, the lock structure of the screen window of the present invention can effectively prevent the screen window from being blown laterally or move by strong wind, and avoid the screen window from colliding with the fixed window frame or other moving window frames, thereby reducing noise and preventing the screen window from being damaged due to collision.
