The utility model relates to a door and window locking plate. It is the base and the lock tongue slide, the opening is arranged on the base, the sliding lock tongue is arranged in the base, a lock tongue front slider corresponding to the base opening is provided with a lock tongue cavity, a lock tongue is arranged on the slide block along the sliding direction of the first straight rack is arranged on the base, and the first straight rack second straight rack, both ends of the reset spring are in contact with the base and the lock tongue slide back to the lock bolt and the base block meshing clutch, when the lock tongue into the lock tongue slide lock tongue cavity, close to the inner wall of the lock tongue lock tongue cavity. The user can press the lock tongue slide to adjust the gap between the inner wall of the lock tongue cavity and the lock tongue, so that the locking tongue can be close to the inner wall of the tongue cavity, so as to prevent the lock tongue from swaying in the lock tongue cavity and loosening the door body. Therefore, the user can adjust the gap between the lock tongue and the inner wall of the lock cavity by itself, so that the lock tongue is not swaying in the lock tongue cavity, so the utility model has the advantages of flexible operation and simple adjustment operation.

门窗锁扣板
本技术涉及门窗锁
,特别是一种门窗锁扣板。
技术介绍
目前,门窗锁,如:门锁一般安装在门体(如:平开门)边缘,对应在门框上设置有供锁舌伸入的榫眼,榫眼会设置有锁扣板,供门锁的锁舌插入以锁紧门体;然而,传统平开门的锁扣板结构,一般包括锁板和底座,锁板上开有安装口,安装口两侧的锁板上开有锁扣板固定孔,锁板的安装口边缘向背部延伸出定位块,定位块伸延入底座内侧壁、并与底座内侧壁相抵,底座两侧延伸出支耳,各个支耳上设置有支耳固定孔;安装时,底座嵌入门框的榫眼,再由螺钉先后穿过锁扣板固定孔和支耳固定孔,将锁扣板固定在门框的榫眼上;然而,上述结构的锁扣板仍存在以下不足之处:(1)底座开口内腔体积大于锁舌体积,便于锁舌顺畅伸入底座内腔,但是由于底座的开口内腔体积大于锁舌体积,门锁与锁扣板扣合后,锁舌与底座存在空隙,锁舌容易晃动,导致门与门框之间松动,门与门框紧凑性大大降低。
技术实现思路
本技术的目的在于提供一种结构简单、合理、锁舌在锁舌腔内卡置牢靠、紧密,锁舌不会晃动,大大提高门体与门框的锁合程度的门窗锁扣板。本技术的目的是这样实现的:一种门窗锁扣板,底座和锁舌滑块,所述底座上设有开口,所述锁舌滑块滑动设置在底座内,锁舌滑块前侧对应底座的开口设置有锁舌腔,所述锁舌滑块上沿其滑动方向设有第一直齿条,所述底座上设有与第一直齿条啮合的第二直齿条,所述锁舌滑块的后侧与底座之间设有复位弹簧,所述复位弹簧的两端分别抵接在底座与锁舌滑块后侧,以使锁舌滑块与底座离合啮合,当锁舌伸入锁舌滑块的锁舌腔时,锁舌紧密抵靠在锁舌腔的内壁。用户可以通过按压并推动锁舌滑块滑动,以调整锁舌腔 ...
