具体实施方式
下面结合附图和实施例对本发明做进一步说明。
参照图1，一些实施例中的半高滑动门锁闭系统包括：锁杆1、底座2、电磁铁驱动装置3、锁销座4、锁销5、压缩弹簧6。
锁杆1固定设置在滑动门上；底座2呈矩形框体结构，其后侧外部安装有一电磁铁驱动装置3，电磁铁驱动装置上的衔铁31从底座后侧面上的孔伸入到底座内部；锁销座4的前端有一锁销 5，锁销的前端从底座的前端面伸出，后端与衔铁31连接；压缩弹簧6设置在底座后侧面与锁销之间；锁盘7可旋转设置在底座前侧面，锁盘可以自己的旋转，但是不能移动，锁盘的上方设有一个与锁销5配合的第一卡口71，下方设有一对分别与左右滑动门上设置的锁杆1配合的第二卡口72，设置为两个相互对称的第二卡口，这可以使左右滑动门锁闭系统的结构通用。
参照图2和图8，为本半高滑动门锁闭系统的另一实施例，锁盘上还固定设置有一旋转轴8，该旋转轴为一轴形结构，旋转轴的中部有一个凸起的轴肩81，轴肩的前部，也就是旋转轴的前端插入到锁盘中，并焊接牢固；轴肩的后部，也就是旋转轴的后端插入到底座的前侧面上的一圆孔(图中未标注)中。为了固定旋转轴8，使其旋转时不脱离底座的前侧面，在旋转轴的后端还开有一个螺纹孔，在旋转轴后端插入到底座前侧面后，再设置一个圆柱体状的卡盖83，卡盖的直径大于底座上圆孔的直径，用一个螺栓(图中未标注)把卡盖固定在旋转轴后端的螺纹孔上。安装好后旋转轴8的轴肩和卡盖把旋转轴卡在底座的前侧面上，使旋转轴不能移出底座2的前侧面，但是可以旋转，而旋转轴又和锁盘焊接在一起，则锁盘也是可以自由旋转的。为了锁盘更好的旋转，在旋转轴上还套有法兰轴承82，而且法兰轴承也可以减少轴肩81和卡盖83的端面摩擦力，提高了其寿命。
锁销5为阶梯轴结构，从后端到前端依次包括第一阶51、第二阶52、第三阶53、第四阶54、第五阶55，第五阶设置在锁销的最前端，其穿出底座前侧面，在电磁铁不通电时锁销是可以进入到第一卡口的,锁住锁盘7。第四阶的直径大于第五阶的直径，这使得第五阶可以穿出底座上的孔，而第四阶不能穿出底座，这 样对锁销5也起到一个限位的作用，使锁销始终处在底座内。第四阶54的直径大于压缩弹簧的外径，第三阶53的直径小于压缩弹簧的内径，这样使得第三阶可以穿入压缩弹簧6内，如此压缩弹簧可以穿过衔铁31和锁销的第三阶53，同时压缩弹簧6的前端抵住第四阶54的侧面，压缩弹簧的后端抵住底座2的后侧面。衔铁31为圆柱形，其前部设置有一横截面为T形的槽311，槽311的尺寸设置为与锁销5的第一阶和第二阶可以相配合，这样锁销的第一阶和第二阶插入到槽311内，使锁销5与锁销座4配合连接。锁销座呈阶梯状的中空圆柱结构，其直径后端大，前端小；锁销5的第三阶和第四阶穿入锁销座4中空部分，用一销9同时穿过锁销和锁销座，从而固定锁销和锁销座，使压缩弹簧在带动锁销运动时，也可以带动锁销座同步运动。
在生产过程中可能会有制造误差的出现，比如锁销与衔铁同轴度不够，这样电磁铁拉动锁销后，锁销可能会出现卡顿的现象，为了避免此现象的发生，在衔铁和锁销之间还增加了一个弹性调节装置，在衔铁的槽311后方再开设一个圆孔，再在圆孔内依次设置小弹簧313和钢珠314，这样在锁销等其部件的制造误差过大时，此结构可以起到微调的作用，避免锁销卡住不能回弹的现象发生。
参照图5和图6,在一些实施例中,在半高滑动门锁闭系统处于解锁状态时，锁盘7没有锁销5的定位作用，可能在受震动的情况下不稳定，为了增加锁盘的稳定性，在底座的前端面上固定设置了碰珠21，碰珠凸出于底座2前端面，碰珠21与的锁盘7的后端面相抵合，滑动门解锁时，电磁铁断电，锁销5在压缩弹簧6的压缩弹性力下对锁盘7施加一个压力，此时锁销配合碰珠 对锁盘7起到了一个弱限位的作用，防止震动导致锁盘的转动，使锁盘保持在等待锁闭状态。当然为了进一步增大限位的作用，在锁盘7的端面设置多个凹座73，通过使碰珠21与凹座73配合实现增大限位的作用。碰珠21可以采用两个螺母固定一个螺杆的方式，螺杆伸出底座前侧面与锁盘接触。
在另一个实施例中，为了记录系统当前的状态，在底座内部还设置有锁闭状态开关10和打开状态开关20，所述开关上都设置有弹性机械结构(图中未标出)，由于锁销座4的阶梯结构的设计，再通过对锁闭状态开关10和打开状态开关20位置的设计，使当系统处于锁闭状态时，锁销座4大直径处的压住弹性机械结构，锁闭状态打开开关10上的弹性机械结构压缩，打开状态开关20上的弹性机械结构不被压住，从而释放，此时开关会发出锁闭信号，系统会显示状态为锁闭状态；当解锁时，锁销座4大直径处的压住弹性机械结构，打开状态开关20的弹性机械结构压缩，锁闭状态开关10的弹性机械结构释放，此时开关会发出解锁信号，系统会显示状态为打开状态。
在系统出现问题，比如断电等情况发生时，滑动门不能打开，会带来一些安全性的问题。因此，在一些实施例中，增加了手工机械控制的部分，在锁销座4上设置了一轴心与锁销轴心平行的圆孔，圆孔内固定配合设置手动解锁推杆30。这里的手动解锁推杆与锁销座可以通过螺纹配合来固定，也可以采用铆接，焊接等其它一些方式来固定。
为了进一步说明半高滑动门锁闭系统，下面对本系统的运行过程作介绍。
参照图2和图3，此时为半高滑动门锁闭系统处于锁闭状态 时的视图，此时锁销5穿过第一卡口71，限制住了锁盘7的旋转，锁杆1卡入了第二卡口72内，此时左右滑动门处于闭合状态，由于锁盘7已经被锁销5限制的转动，实现了锁杆1的固定，即此时滑动门锁定闭合，不能左右移动。为了打开滑动门，也就是要先解锁，就需要电磁铁1通电吸合，拉动锁销5，并使压缩弹簧6压缩，此时锁销5从第一卡口71中抽出，从而解除了锁销5对锁盘7的限制，此时电动机可以带动滑动门水平移动，而锁杆1与滑动门钢性连接，也就带动了门锁杆水平移动。锁杆1也就带动了锁盘7的旋转，此时锁杆脱离了第二卡口72，实现了滑动门的解锁。
参照图4和图5，此时为半高滑动门锁闭系统处于打开状态时的视图，此时锁销5没有穿过锁销孔7，打开滑动门后，锁杆1会带动锁盘7旋转，此时碰珠21会与锁盘7上平面压合，锁销5也会在压缩弹簧的弹力下压住锁盘7，防止震动导致锁盘7的转动，使锁盘7保持在等待锁闭状态。
上述通过具体实施例对本发明进行了详细的说明，这些详细的说明仅仅限于帮助本领域技术人员理解本发明的内容，并不能理解为对本发明保护范围的限制。本领域技术人员在本发明构思下对上述方案进行的各种润饰、等效变换等均应包含在本发明的保护范围内。
