在具体实施例中，第一控制板210、第二控制板220以及第三控制板230与壳体架100之间均还设置有卡扣结构，以便于第一控制板210、第二控制板220以及第三控制板230相对壳体架100推进到极限位置时，第一控制板210、第二控制板220以及第三控制板230相对壳体架100可以进行卡扣连接，不容易发生晃动。
在具体实施例中，控制板210、220和230与架体100之间均还设置有卡扣结构，以便于控制板210相对架体100推进到极限位置时，控制板210相对架体100可以进行卡扣连接，不容易发生晃动。
在具体实施例中，背板300通过插针组件与控制板组件200电连接。具体地，可以是背板300上设置有插针，控制板组件200上对应设置有针槽以进行配合实现电连接。其他实施例中，也可以是控制板组件200设置有插针，背板300设置有针槽进行配合。且具体的，插针与针槽的配合方向与控制板组件200的滑动方向相同。
在具体实施例中，控制板组件200的滑动方向进一步垂直于背板300，因此，在控制板组件200相对架体100进行抽出时，可以直接远离背板300，进而解除插针与针槽的配合关系。
在上述实施例的基础上，壳体还可以包括一用于阻挡控制板组件200从架体100上抽出的阻挡板，阻挡板置于第一侧面上。阻挡板可以相对外壳进行移动以解除对控制板的抽出阻挡，进而便于控制板组件200相对外壳进行抽出。
具体地，阻挡板可以相对外壳进行滑动或者转动或者拆卸，从而使得在外壳在控制板组件200的滑动面上露出一个窗口，从而控制板组件200可以从窗口中进行抽出或者推进，从而相对外壳进行抽出。
在上述结构的基础上，对背板300的拆卸和安装方式说明如下：
在背板300通过螺钉或卡扣的方式与架体100进行连接时：
在进行拆卸时，首先将盖板从壳体上拆出，然后移除侧面上的阻挡板， 拉动推拉板240使控制板组件200从架体100内抽出，此时控制板组件200中的控制板210、220和230移出壳体且与背板300断开连接，随后扭动螺钉或者解除卡扣连接，从而可以解除背板300与架体100的连接关系，将背板300沿垂直于顶板150的方向取出，从而完成拆卸。在一些实施例中没有阻挡板结构的，可以直接省略该步骤的拆卸。
在具体实施例中，螺钉的长度方向可以垂直于顶板150，因此可以直接从垂直于顶板150的方向对背板300与进行拆卸与取出，在具体场景中，由于背板300远离顶板150一侧的周边还可能设置有其他的器件，因此直接从垂直于顶板150的方向对背板300与进行拆卸与取出，可以无需对其他器件进行拆卸，极大的缩减了拆卸流程。
在安装时，安装的步骤与拆卸的步骤相反，也即是最后拆卸的部件先安装，先拆卸的部件最后安装。先将背板300通过螺钉或卡扣的方式固定在架体100，随后将控制板组件200相对架体100进行推进，再将阻挡板固定在壳体上推拉板所在的一侧面上，然后将盖板410装到壳体上。
在背板300通过第一卡槽的方式与架体100进行连接时：
相似的，在进行拆卸时候，首先将盖板410从壳体上拆出，然后移除侧面上的阻挡板，拉动推拉板240使控制板组件200从架体100内抽出，此时控制板组件200中的控制板210、220和230移出壳体且与背板300断开连接，随后直接将背板300从第一卡槽抽出，从而完成拆卸。在一些实施例中没有阻挡板结构的，可以直接省略该步骤的拆卸。
在进行安装时，操作步骤与拆卸的步骤顺序相反。先将背板300推进到第一卡槽中，随后将控制板组件200相对架体100进行推进，使控制板组件200中的各控制板与背板300连接，再将阻挡板固定在壳体上推拉板所在的一侧面上，然后将盖板410固定在壳体上，从而完成背板300的连接。
本实用新型提供的放映机，通过盖板将电子箱模组封设于放映机的壳体内，且电子箱模组的顶板与盖板邻接设置，打开盖板电子箱模组的顶板和背板可露在外面，控制板组件中控制板的一端固设在推拉板上，推拉板贴合设置于架体上且推拉板与壳体的一个侧面邻接设置，在拆卸时可以直 接从壳体的侧面抽出推拉板，抽出推拉板时控制板组件中的控制板从架体中滑出，同时推拉板离开架体与壳体且控制板组件与背板断开连接，从而可以方便地从壳体的另一面将背板取出。即在背板的拆卸过程中，只需要将壳体的盖板拆卸，然后断开与背板连接的控制板，即可快捷地将背板取出。需要拆卸的器件少，拆卸过程简单，使背板可以快速地拆卸与安装，给转接析的检修与定期维护带来了便捷。
以上仅为本实用新型的实施方式，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结果或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
