Embodiment Construction
[0017] The technical solutions of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0018] The push-pull casement window opening locking device of the present invention has a structure comprising upper and lower window locks 7, 8, through which the window sash 1 can be fixed on the upper and lower window rails 3, 4 to open the window. bit lock, such as Figure 4 shown.
[0019] The upper window lock 7 includes an upper lock frame 5 installed in the corresponding rail groove of the upper window rail 3 through the front and rear rollers 2 and an upper locking mechanism based on the upper lock frame 5. The upper locking mechanism includes an upper pressure block 14 , the upper pressing block 14 is movably installed in the upper lock frame 5 (with upper and lower degrees of freedom), the position of the upper pressing block 14 corresponds to the upper rotation axis position 11 of the window sash 1, and ...

The invention discloses a window opening locking device for a push-pull casement window. The window opening locking device is characterized in that an upper window lock comprises an upper lock rack mounted in an upper window track through wheels and an upper locking mechanism based on the upper lock rack, a lower lock comprises a lower lock rack mounted in a lower window track through wheels and a lower locking mechanism based on the lower lock rack, the lower locking mechanism comprises a warped plate, an ejector pin and a lower compression block, the warped plate is hinged to warped shafts, the lower compression block is located in the lower lock rack, the upper and lower positions of the lower compression block is regulated by a manual screwing screw, the front end of the warped plate is connected with the lower compression block, the rear end of the warped plate supports the lower end of the ejector pin, and the ejector pin is located in the vertical edge of a sash rotary shaft position; the upper locking mechanism comprises an upper compression block which is arranged in the upper lock rack and can freely vertically move, and the upper end of the ejector pin is connected with the upper compression block; an upper compression strip and a lower compression strip are arranged at the top and the bottom of each of the upper window track and the lower window track, and concave and convex structures meshing during compression are arranged between each compression strip and the corresponding compression block. The window opening locking device has the advantages that the lever principle is used to allow the upper compression block and the lower compression block to be compressed onto the corresponding compression strips at the same time, and the window opening position of a sash is stabilized by the meshing concave and convex structures.
Description
technical field [0001] The invention relates to a window component for house construction, in particular to a window locking device for a push-pull casement window. Background technique [0002] The so-called push-pull casement window is a window whose sash can be opened by sliding left and right along the window rail and the sash can be rotated outwards to open. No. CN204457296U). [0003] In the structure of the authorized patent, the window sash can be opened by pushing and pulling left and right along the window rail when the window locking mechanism is unlocked. When the window sash is rotated outward to open, the window locking mechanism locks and fixes the window sash in the window opening position so that it cannot be moved. [0004] Including the authorized patent "Push-Pull Casement Window", the structure of the window locking mechanism is various, but most of them rely on friction to lock the window sash, and there is a problem of unstable locking. Invention co...
