附图说明
为更清楚地说明本实用新型实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型的一些实施例，对本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本实用新型电源安装模组的结构示意图；
图2是本实用新型电源安装模组的拆分状态示意图；
图3是电源另一侧的结构示意图。
具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
请参阅图1至图3，图1是本实用新型一种电源安装模组的组装状态示意图，包括电源架体1和电源3，电源架体1具有一个用于容纳电源3的腔体2，腔体2的一侧具有一开口，电源3通过该开口进入腔体2内。电源架体1还具有侧板11，腔体2的两侧均设置有侧板11，侧板11上设置有第一导向孔21。电源3具有第一导向柱31，第一导向柱31与第一导向孔21相对设置，第一导向柱31与第一导向孔21相配合以提供电源3向腔体2装配过程中推进方向上的引导和装配后的限位。
电源3与电源架体1进行装配时，电源3从腔体2的开口处进入，当推进到一定位置时，第一导向柱31与第一导向孔21接触，在继续推进的过程中，第一导向柱31进入到第一导向孔21内，第一导向柱31与第一导向孔21的配合，可以提供电源推进方向上的引导，使电源3在推进方向上不会产生偏离。在电源3装配到腔体2内，第一导向柱31与第一导向孔21的配合还可以给电源提供在水平方向上的限位，即防止电源3在水平方向上发生偏移。
本实施例的安装模组不使用滑轨结构，采用导向柱与导向孔相配合 进行安装导向，不仅结构简单，且能快速地进行安装与拆卸。
在上述实施例的基础上，在电源3上设置第一导向孔，在电源架体1的侧板上设置对应的第一导向柱也是可以的，与上述设置的作用相同，同样可以达到导向和限位的作用。当导向孔和导向柱为多组，例如两组时，为达到受力平衡，将导向装置分别布置在电源3两侧，两侧的两组导向柱和导向孔可以为相同设置，如腔体2的开口两相对外缘上分别均设有一第一导向柱，或均设有一第一导向孔21；也可以为不同设置，腔体2的敞口两相对外缘分别设有一第一导向柱、一第一导向孔。导向装置数量越多，则变化越多样，同一侧的设置也可以进行不同变化。
为便于说明，将腔体2正对开口的面称为内侧面，开口上下的面分别称为上面和下面，左右两面分别称为左面和右面。电源3的第一面为在装配后与电源架体1的内侧面接触的面。电源的第二面指电源3装配到电源架体1后，朝向外的面，也就是与第一面相对的面。该第一导向柱31或第一导向孔21既可以设于电源3上也可设于电源架体1的内侧面或外缘上，只需两者的位置和数量对应即可。
进一步请参阅图2和图3，图2为电源安装模组的拆分状态示意图，图3为电源3另一侧的结构示意图。本实施例以在电源3上设置第一导向柱31，在电源架体1的两侧面上设置对应的第一导向孔21为例，第一导向柱31的直径与第一导向孔21的直径相同，位置相对，即在装配时第一导向柱31可以恰好插入第一导向孔21内。
电源架体1上还设置有第二导向孔22或第二导向柱32，相对应地，电源3还具有第二导向柱32或第二导向孔22。第二导向孔22设置在电源架体1上还是设置在电源3上，根据具体的应用需求进行设计。以下的实施例以电源架体1上设置第二导向孔22，电源3上设置第二导向柱32为例进行说明。
电源架体1上设置有第二导向孔22，第二导向孔22置于腔体2的内侧面。电源3上的第二导向柱32置于电源33的第一面上。第二导向孔22的个数可以为一个、两个、三个、四个等，相应地，第二导向柱32的个数也可以为一个、两个、三个、四个等，第二导向柱32的个数 与第二导向孔22的个数需要相同。当设置为一个时，可以将第二导向孔22设置在电源架体1内侧面的中间部位；当设置为两个时，可以在电源架体1内侧面的左边区域设置一个第二导向孔22，右边区域设置一个第二导向孔22；此时电源3上的第二导向柱32的位置与第二导向孔22的位置相对应。
由于腔体2的内尺寸略大于电源3的外部尺寸，两者之间有间隙，电源3滑入腔体2后，内部可能会发生晃动，对电源3的稳定性造成影响，因此第二导向柱32与第二导向孔22的匹配设置，可以对电源3的内侧进行限位，避免晃动，作为电源3的限位装置使用。同上述的导向装置相同，当第二导向孔和第二导向柱为两组时，两侧的导向柱和导向孔可以为相同设置，如均为导向孔对导向柱或导向柱对导向孔，也可以为不同设置，如一端为导向孔对导向柱另一端为导向柱对导向孔。限位装置数量越多，则变化越多样，同一侧的设置也可以进行不同变化。
安装时电源3从电源架体1的开口进入并向腔体2内推进，当推进到一定距离时，第一导向柱31插入第一导向孔21内，即表明电源3的位置为预设的安装位置，电源3可以顺着两者配合的方向继续向内推进。当第一导向柱31插入第一导向孔21时，第一导向孔21起到了安装引导的作用，当第一导向柱31插入第一导向孔21后，第一导向孔21可以对第一导向柱31即电源3在推进方向相垂直的面上进行了约束，起到了限位的作用。由于第一导向孔21和第一导向柱31在电源3推进时提供了导向作用，当推进到一定距离时，第二导向柱32与第二导向孔22接触，第二导向柱32能够准确地插入第二导向孔22，即第二导向柱32不会偏离第二导向孔22。使得电源3能够快速地装配到电源架体1上。避免出现电源3推进后内部的限位装置被遮挡无法观察，难以调整第导向柱22和第二导向孔32两者相对位置的问题。
在上述各实施例的基础上，电源3还包括一安装板34，安装板34固设于电源3的第二面上，安装板34的两端凸出于电源3的本体，第一导向柱31分别固设于安装板34的两端。作为一种变换的结构，电源3上不设置安装板，而是在电源的相对两侧设置侧板，也就是说，电源 3的左侧设置有一侧板，相应地，电源3的右侧同样设置有一侧板，第一导向柱31分别置于两侧板上。电源3装配到电源架体1上时，腔体两侧的侧板与电源两侧的侧板相贴合。
为了方便电源3的安装与拆卸，可以在安装板34上设置把手。在安装与拆卸电源3时，可以通过该把手对电源进行推进与拉出，操作方便快捷。在电源独立于电源架体1时，可以通过把手来提携电源3。
各实施例中，第一导向柱31的长度或第一导向孔21的深度大于腔体2深度的六分之一，小于或等于腔体2深度的二分之一。第一导向柱31和第一导向孔21为达到安装导向的作用，长度不能太短，否则只有当电源3推进到接近腔体2内侧时，导向结构之间才接触，起不到预设的导向作用。当然长度也不宜过长，否则造成与其它零部件的抵触以及浪费物料的后果。
与上述各个实施例相结合，电源3上还设有螺钉33，电源架体1的侧板上还对应设有螺栓孔23，电源3通过螺钉33可拆卸地安装于电源架体1上。螺栓孔23的位置及直径与螺钉33的位置及尺寸相适配，当电源3到达安装的预定位置时，即第一导向柱31插入第一导向孔21内后，将电源3向体腔2内推进，直至电源3的凸出端抵住腔体2的侧板，将螺钉33拧入螺栓孔23内，使电源3固定于电源架体1上，安装方式简单快速。由此，电源3在推进方向上即横向方向上由螺钉33和螺栓孔23限位，前端由限位装置在推进方向的垂直面即纵向方向上进行限位，导向装置也在电源3的后端进行了横向方向上的限位，电源3的各个方向上均被限位，无法晃动，避免电源3在使用过程中产生位移，保证了电源3的稳定性。
为增强对电源3的稳固性，螺钉33为两侧各两个，且螺钉33为松不脱螺钉，该螺钉33压铆或涨铆在电源模块3上，不会脱落，避免零件丢失，便于安装操作，加快了安装速度。在上述实施例的基础上，本实用新型还提供一种放映设备，该放映设置内具有上述实施例所述的电源安装模组。
使用本实用新型的电源安装模组及其放映设备，在电源3的安装方 向上设计有结构简单的导向结构，对电源模块的推进安装进行导向，实现快速安装与拆卸，相比于滑轨的安装方式更简单，且易于加工与安装。
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构或等效流程变换，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。
