Description

一种锁定机构
技术领域
本发明涉及屏幕固定领域，更具体地，涉及一种用于屏幕固定的锁定机构。
背景技术
现有投影型图像拼接显示装置中需要经常对投影箱内的设备进行维护，根据维护方式的不同可分为前维护方式和后维护方式。前维护方式一般需要将屏幕设置成可移动设备，当需要进行前维护时，将屏幕从箱体上拉出，维护好后再将屏幕恢复原位并锁紧。现有的屏幕锁紧结构是采用锁钩机构，在背投箱体的两边设置两个挂钩装置，在屏幕单元框架上对应设置两个锁钩装置，实现对屏幕单元的锁定。但是由于屏幕单元尺寸较大，一个锁钩只能对屏幕单元进行单点锁定，两边的单点锁定形成的仅仅是线锁定，稳固性差。此外，屏幕单元的生产制造和拼接过程中容易产生尺寸误差或者结构变形，由于现有的锁紧机构稳固性差，无法通过稳固锁紧的方式来弥补上述缺陷，导致系统中各屏幕单元与背投箱之间容易形成倾角或者容易造成屏幕单元脱离背投箱，影响屏幕单元的投影效果。
发明内容
本发明为克服上述现有技术所述的至少一种缺陷（不足），提供一种锁紧功能可靠的锁定机构。
为解决上述技术问题，本发明的技术方案如下：
一种锁定机构，包括安装板，还包括用于安装在背投箱体上的两个固定锁钩、安装在安装板上的旋转紧扣结构，旋转旋转紧扣结构能使其与两个固定锁钩相扣合。
与现有技术相比，本 发明 技术方案的有益效果是：
本发明的锁定机构上设置了两个固定锁钩，旋转紧扣结构通过旋转与两个固定锁钩实现扣接锁紧，解决了现有技术中由于单点锁定导致锁紧功能不可靠的问题，利用该锁定机构能使屏幕单元紧密稳固地锁定在背投箱体上，克服了 各屏幕单元与背投箱之间容易形成倾角或者容易造成屏幕单元脱离背投箱的技术问题。

具体实施方式
附图仅用于示例性说明，不能理解为对本专利的限制；
为了更好说明本实施例，附图某些部件会有省略、放大或缩小，并不代表实际产品的尺寸；
对于本领域技术人员来说，附图中某些公知结构及其说明可能省略是可以理解的。
下面结合附图和实施例对本发明的技术方案做进一步的说明。
实施例 1
如图 1 所示，为本发明中一个锁定机构的结构示意图。参见图 1 ，本实施例的锁定机构包括安装板 1 、固定锁钩 2 和旋转紧扣结构 3 ；其中安装板 1 是用于固定在屏幕框架上的，固定锁钩 2 包括两个，用于安装在背投箱体上；旋转紧扣结构 3 安装在安装板 1 上。本实施例通过旋转紧扣结构 3 的旋转使其与两个固定锁钩 2 相扣接，实现两点锁紧。实际应用时，可以通过在屏幕框架相对的两边设置安装板 1 和旋转紧扣结构 3 ，在背投箱体对应的边上安装固定锁 2 ，就可以对屏幕实现四点成面的锁定，从而使屏幕稳固且紧密地安装在背投箱体上。
具体地，如 1 和图 2 所示，旋转紧扣结构包括转轮 31 、第一活动锁钩 32 和第二活动锁钩 33 ，转轮 31 安装在安装板 1 上，第一活动锁钩 32 和第二活动锁钩 33 分别套装在转轮 31 的侧壁上，其中第一活动锁钩 32 和第二活动锁钩 33 与两个固定锁钩 2 以一对一的方式相对应，转轮 31 的旋转能使第一活动锁钩 32 、第二活动锁钩 33 与对应的固定锁钩 3 相扣合。
具体地，如图 3 所示，为本实施例中安装板 1 的结构示意图。参见图 3 ，安装板 1 上设有限位槽 11 、上导向槽 12 和下导向槽 13 ，上导向槽 12 和下导向槽 13 分别位于限位槽 11 的两端且分别与限位槽 11 相通，上导向槽 12 和下导向槽 13 作为第一活动锁钩和第二活动锁钩的运动限位和运动导向；安装板 1 的限位槽 11 内还设有轴孔 14 ，用于装配转轮，使该转轮能绕此轴孔 14 转动。装配时，如图 1 所示，转轮 31 安装在限位槽 11 内，第一活动锁钩 32 卡在上导向槽 12 内，第二活动锁钩 33 卡在下导向槽 13 内，转轮 31 的旋转带动第一活动锁钩 32 沿着上导向槽 12 作向上运动、第二活动锁钩 33 沿着下导向槽 13 作向下运动从而与对应固定锁钩 2 实现扣合。限位槽 11 、上导向槽 12 和下导向槽 13 的设置避免了转轮转动时第一活动锁钩 32 和第二活动锁钩 33 的左右运动，保证了第一活动锁钩 32 和第二活动锁钩 33 在转轮 31 的转动下只做向上或者向下运动，从而很好地与背投箱体上的固定锁钩相配合实现锁定功能。
在具体实施过程中，第一活动锁钩和第二活动锁钩可以采用相同的结构实现，具体如图 4 所示。下面以第一活动锁钩为例阐述第一活动锁钩和第二活动锁钩的结构。
参见图 4 ，第一活动锁钩 32 包括方形孔 321 和锁棒 322 ，锁棒 322 的末端设有弯角面 323 。装配时，方形孔 321 套装在转轮侧壁上且方形孔 321 的内侧面与转轮侧壁相切，保证转轮转动时能够带动第一活动锁钩 32 转动；第一活动锁钩 32 的锁棒 322 卡在上导向槽上；第一活动锁钩 32 的弯角面 323 是用于和对应固定锁相配合固定的，此时，固定锁可以采用如图 5 所示的结构实现，与第一活动锁钩 32 上的弯角面相对应地设置固定锁钩的弯角面 21 ，两个弯角面相配合能够实现紧密的扣合。相应地，第二活动锁钩也对应设置方形孔、锁棒和弯角面，其方形孔套装在转轮侧壁上且该方形孔的内侧面与转轮侧壁相切，第二活动锁钩的锁棒卡在下导向槽上；第二活动锁钩的弯角面用于和对应的固定锁相配合固定的。
在具体实施过程中，转轮可以采用如图 6 所示的结构实现。参见图 6 ，转轮 31 侧壁的中部位置设有凸沿 311 ，凸沿 311 的两侧形成有第一圆台 312 和第二圆台 313 ，第一圆台 312 和第二圆台 313 上设有相互错位的第一凹槽位 3121 和第二凹槽位 3131 。装配时，第一活动锁钩的方形孔和第二活动锁钩的方形孔分别套装在第一圆台 312 和第二圆台 313 的侧壁上，此时第一活动锁钩的方形孔和第二活动锁钩的方形孔各自的内侧面分别与第一圆台 312 和第二圆台 313 相切，使得转轮转动时第一活动锁钩和第二活动锁钩能够随之转动；此外为了使转轮转动时能够时刻带动第一活动锁钩和第二活动锁钩转动，第一活动锁钩的方形孔需要始终与第一圆台 312 相切，第二活动锁钩的方形孔始终与第二圆台 313 相切，此时可以将第一活动锁钩的方形孔的内角、第二活动锁钩的方形孔的内角均设置为倒圆角，使得第一活动锁钩的方形孔、第二活动锁钩的方形孔分别与第一凹槽位 3121 、第二凹槽位 3131 形成线接触，配合安装板上的上导向槽和下导向槽，使得转轮的转动能够转化为第一活动锁钩、第二活动锁钩的向上或者向下的直线运动。
转轮旋转时，第一圆台 312 上的第一凹槽位 3121 转到下方，从而带动套装在其上的第一活动锁钩沿着上导向槽作向上运动，与对应固定锁钩扣合，第二圆台 313 上的第二凹槽位 3131 到上方，从而带动套装在其上的第二活动锁钩在重力作用下沿着下导向槽作向下运动，与对应的固定锁钩扣合。优选地，第一凹槽位 3121 和第二凹槽位 3131 可以设置其横切面相互垂直。
在具体实施过程中，为了便于旋转转轮，本实施例还设置一个手柄结构来转动转轮。具体地，安装板安装转轮的背面设有手柄结构，手柄结构上设有第一通孔，转轮轴向上设有第二通孔，安装板的限位槽上设有轴孔，手柄结构通过第一固定件穿过该第一通孔、轴孔和第二通孔与转轮连接成一体，手柄结构的转动带动转轮旋转。在一种优选的实施方式中，手柄结构可以采用如图 7 和 8 所示的拨片实现。如图 7 和 8 所示，拨片 4 上设置有第一通孔 41 和钩位 42 ，第一通孔 41 与转轮上的第二通孔相配合，通过第一固定件固定成一体，使得拨片 4 转动时能够带动转轮转动。钩位 42 在屏幕锁定时贴合于屏幕表面，防止拨片 4 外凸，影响日常使用；在解锁时，通过钩位 42 即可将拨片 4 旋转拉出。
在具体实施过程中，为了防止转轮转动时，脱离安装板和手柄结构，本实施例还设置了封板。具体地，如图 6 所示，转轮 31 上设置有第二通孔 314 ，第二通孔 314 两端分别设有中间与第二通孔 314 相通的凸台 315 ，其一端的凸台 315 穿过安装板限位槽上的轴孔与手柄结构上的第一通孔相接，其另一端的凸台活动连接有一封板，该封板固定在安装板上。由于封板固定在安装板上，手柄结构转动时，封板固定不动，转轮随着转轮的转动绕着封板转动。具体地，如图 9 所示，为封板 5 的结构，封板 5 上设置有设有固定孔 51 和封板轴孔 52 ，封板 5 通过固定孔 51 结合螺钉等固定件固定在安装板上，封板 5 通过第二固定件穿过其上的封板轴孔 52 与转轮一端的凸台活动连接。
实施例 2
本实施例为实施例 1 的一较佳实施例，图 12 为本实施例的结构的部分爆炸图。参见图 12 ，本实施例的锁定机构包括：安装板 10 、固定锁钩 20 、旋转紧扣结构 30 、拨片 40 、封板 50 、第一固定件 60 和第二固定件 70 ；
安装板 10 上设置有限位槽、上导向槽和下导向槽，上导向槽和下导向槽分别位于限位槽的两端且分别与限位槽相通；
固定锁钩 20 包括两个，分别固定在背投箱体上，用于与旋转紧扣结构 30 配合锁定；固定锁钩 20 位置的设定以能够与旋转紧扣结构 30 相配合为准，在本实施例中，两个固定锁钩 20 分别设置在上导向槽上部和下导向槽下部；固定锁钩 20 一端设置有弯角面，可以用于与第一活动锁钩或者第二活动锁钩上的弯角面相配合；此外固定锁钩 20 上可以设置对应的孔 202 ，便于其固定在背投箱体上；
旋转紧扣结构 30 包括转轮 301 、第一活动锁钩 302 和第二活动锁钩 303 ；
转轮 301 侧壁的中部位置设有凸沿，凸沿的两侧形成有第一圆台和第二圆台，第一圆台和第二圆台上设有横切面相互垂直的第一凹槽位和第二凹槽位，转轮 301 的轴向方向上设置有第二通孔，第二通孔两端分别设有中间与第二通孔相通的凸台；
第一活动锁钩 302 和第二活动锁钩 303 分别包括方形孔和锁棒，锁棒的末端设有弯角面，方形孔的内角设为倒圆角。
拨片 40 上设有第一通孔和钩位；封板 50 上设有固定孔和封板轴孔。
装配时，如图 10-12 所示，将 2 个固定锁钩 20 安装背投箱体 80 合适的位置，将安装板 10 固定安装在屏幕框架上；接着，将第一活动锁钩 302 和第二活动锁钩 303 分别利用各自的方形孔套装在转轮 301 的第一圆台和第二圆台的侧壁上，然后将转轮 301 安装在安装板 10 的限位槽上，其中转轮 301 第二通孔一端的凸台穿过限位槽上的轴孔与拨片 40 上的第一通孔对接，然后利用第一固定件 60 将拨片 40 和转轮 301 固定成一体，第一活动锁钩 302 和第二活动锁钩 303 上的锁棒分别卡在上导向槽和下导向槽内；然后将转轮 301 第二通孔另一端的凸台和封板 50 上的封板轴孔对接，并利用第二固定件 70 实现活动连接，最后将封板 50 固定在安装板 10 上。
由于第一活动锁钩 302 和第二活动锁钩 303 的方形孔内角为倒圆角，使得该倒圆角与转轮 301 上的第一凹槽位和第二凹槽位相遇时能够保持线接触，保证转轮的转动能够带动第一活动锁钩 302 和第二活动锁钩 303 的上下运动。
如图 11 所示，当需要锁定时，将 拔片40 顺时针转 90 °，带动转轮 301 顺时针转 90 °，转轮 301 上的第一凹槽位转到下部，与第一凹槽位相对的第一圆台侧壁转到上部，带动第一活动锁钩 302 沿着安装板 10 内的上导向槽向上运动，与对应的固定于背投箱体 80 上的固定锁钩 20 配合，实现上锁定位的锁定；同时转轮 301 的第二凹槽位转到上部，与第二凹槽位相对的第二圆台侧壁转到下部，第二活动锁钩 303 在重力作用下沿着安装板 10 上的下导向槽向下运动，与对应的固定锁钩 20 配合，实现下锁定位的锁定。
当需要解锁时，拔片40 逆时针转 90 °，带动转轮 301 逆时针转 90 °，转轮 301 上的第一凹槽位朝向上部而对第一凹槽位相对的第一圆台上的侧壁朝向下部，在重力作用下第一活动锁钩 302 沿着安装板 10 上的上导向槽向下运动，与对应的固定于背投箱体 80 上的固定锁钩 20 脱离，实现上锁定位的解锁，同时转轮 301 上的第二凹槽位转到上部，带动第二活动锁钩 303 沿着安装板 10 上的下导向槽向上运动，与背投箱体 80 上的对应固定锁钩 20 脱离，实现下锁定位的解锁。
在具体应用时， 可以通过在屏幕框架相对的两边设置安装板 10 和旋转紧扣结构 30 ，在背投箱体对应的边上安装固定锁 20 ，就可以对屏幕实现四点成面的锁定，从而使屏幕稳固且紧密地安装在背投箱体上。
