所述固定支架组件1包括固定支架11、设置于所述固定支架11 远离所述推拉盖板3一侧并分别与所述导向部24连接的支撑件12以及开设于所述固定支架11靠近所述推拉盖板3一端的避让通槽13，所述支撑件12所处位置与所述防尘网骨架21的所述导向部24对应设置，用于连接对应所述导向部24，所述避让通槽13用于让位收容所述塑胶铆钉4。
在本实施方式中，所述支撑件12为硅胶套，所述导向部24为导向柱，值得一提的是，所述导向柱的数量并无限制，比如，在本实施方式中，导向部24选用三根导向柱，此时所述支撑件12对应包括三个硅胶套，分别用于卡接防尘网组件2上的三根导向柱，所述硅胶套对所述导向柱具有紧固和支撑作用，能有效防止所述防尘网组件2在配套设备内部晃动。作为一种可选方式，所述支撑件12也可以为磁铁，所述导向部24则为金属块，通过磁铁对金属块的吸力来起到紧固作用，且不妨碍所述防尘网组件2的拆卸。
在本实施方式中，所述固定支架11包括两个，两个所述固定支架11相互盖设并通过热熔方式固定连接。两个所述固定支架11结构简单且完全相同，加工时可以共用一套模具，降低了加工难度和加工成本。另一方面，两个所述固定支架11均设有与所述防尘网骨架21对应的支撑骨架14，以确保安装好所述防尘网组件2后不影响防尘网22的作用面积。
值得一提的是，所述防尘装置还包括壳体6，所述固定支架组件1的内侧周缘设有导向槽15，所述防尘网骨架21卡设于所述导向槽15并与所述固定支架组件1形成滑动连接，从而防尘网组件2通过推动推拉盖板3沿所述收容空间内侧的导向槽15，导入至固定支架组件1内部。同时，由于所述防尘网组件2具备良好的韧性，在拆装过程中可进行弯折，使所述可防尘网组件2与配套设备的拆装不易受拆装位置附近的空间限制。比如，所述配套设备为投影设备，该投影设备在超短焦的应用场景中，投影设备距离投影的墙壁很近，可将所述防尘网组件2弯折，并通过推拉所述推拉盖板3使所述防尘网组件2从所述投影设备的外部推入所述投影设备内部或从投影设备的内部 抽离至所述投影设备的外部，在安装过程中，弯曲所述防尘网组件2，使所述防尘网骨架21卡设于所述导向槽15，能方便、准确地安装所述防尘网组件2。在本实施方式中，所述导向槽15还包括呈弯曲结构且位于所述壳体6外部的第二导向槽151，所述第二导向槽151与所述导向槽15为一体结构或者可拆卸结构，所述防尘网组件2还包括位于所述壳体6外部呈弯曲结构的导轨25，所述防尘网骨架21的下侧卡设于所述导轨25并形成滑动连接，所述导轨25的一端抵接于所述导向槽15，且所述导轨25与所述导向槽15为一体设置或者可拆卸结构。该结构的设置，在弯曲安装所述防尘网组件2时，使得所述防尘网组件2能更方便，更准确导入所述固定支架组件1内。
上述结构的设置，不需要移动投影设备的位置即可完成所述防尘网组件2的安装与拆卸，便于经常拆装所述防尘网22进行清洗，即提高了投影设备的使用寿命，同时避免了因移动投影设备而需再次调整焦距、调节投影画面尺寸大小等重复性的工作。
更进一步的，所述固定支架组件1还包括定位柱16和固定孔17，所述定位柱16设于所述固定支架11的上下两侧，所述固定孔17开设于所述固定支架11的安装面，所述固定支架11通过所述定位柱16与所述固定孔17与配套设备固定连接。
更优的，所述固定支架11的安装面上还设有避位槽18，用于避开与配套设备之间的干涉部位。
本实用新型还提供了一种投影设备100，所述投影设备100包括机壳20和如上所述的防尘装置10。
在本实施方式中，所述机壳的侧壁设有进风口和门扣5，所述固定支架组件1盖设固定于所述进风口，接压所述推拉盖板使所述卡钩32与所述门扣5形成锁合或分离。该结构的设置，在投影设备100外部完成所述防尘网组件2的独立安装与拆卸，大大提高了拆装便利性，降低了操作难度，减少了拆装时间。
相较于现有技术，所述防尘装置包括具有收容空间的固定支架组件、插设于所述收容空间内并与所述固定支架组件形成滑动连接的防 尘网组件以及位于所述防尘网组件一端的推拉盖板。所述防尘网组件包括防尘网骨架和套设于所述防尘网骨架的防尘网，所述防尘网骨架与所述防尘网一体成型，所述推拉盖板与所述防尘网骨架形成可拆卸连接且位于所述收容空间的外侧。所述防尘网组件的结构的设置，使所述防尘网骨架和所述防尘网紧密固定在一起并具有良好的韧性，拆装过程中可进行弯折，并在弯折状态下可进行准确定位拆装，不容易受安装位置附近的空间限制；同时，所述固定支架组件与所述防尘网组件间采用滑动连接结构，所述防尘网组价与所述推拉盖板间采用可拆卸连接结构，使得所述防尘装置便于拆装。另一方面，所述投影设备包括机壳和所述防尘装置，所述机壳的侧壁设有进风口和门扣，所述固定支架组件盖设固定于所述进风口，接压所述推拉盖板使所述卡钩与所述门扣形成锁合或分离，在投影设备外部完成所述防尘网组件的独立安装与拆卸，大大提高了拆装便利性，降低了操作难度，减少了拆装时间。
以上实施例仅为清楚说明本实用新型所作的举例，并非对实施方式的限定；本实用新型的范围包括并不限于上述实施例，凡是按照本实用新型的形状、结构所作的等效变化均包含在本实用新型的保护范围内。
