进一步地，所述卡扣220可以为销钉。所述第一密封圈40的材质可以为硅胶、氟橡胶、聚氨酯发泡胶、丁腈橡胶以及天然橡胶等中的至少一种。所述第二盖板21设有凹槽210，所述第一密封圈40部分容置于所述凹槽210内，从而使所述第一密封圈40相较于所述第二盖体20定位且防止所述第一密封圈40脱离所述第二盖体20。在另一实施方式中，所述凹槽210可以省略，所述第一密封圈40可以通过胶粘剂固定于所述第二盖板21。
本申请所述第一盖体10和所述第二盖体20通过卡槽120和卡扣220的方式进行安装，安装过程方便快捷，且由于省略螺丝等紧固件，在提高生产效率的同时能够避免螺丝对箱体1外观造成影响。
如图4和图5A所示，在本发明一实施例中，所述卡槽120相较于所述第一盖板11所在平面呈倾斜设置，倾斜角度可设置为0-90度。通过使所述卡槽120倾斜设置，可以从一定程度上避免所述第二盖体20脱离所述第一盖体10。如图5B所示，在本发明另一实施例中，所述卡槽120包括第一卡槽部1201 和连通所述第一卡槽部1201的第二卡槽部1202。所述第一卡槽部1201相较于所述第一盖板11所在平面呈倾斜设置，所述第二卡槽部1202平行于所述第一盖板11所在平面。所述卡扣220用于通过所述第一卡槽部1201滑动至所述第二卡槽部1202中。由于所述卡扣220能够容置于所述第二卡槽部1202中，可以防止所述卡扣220滑出所述卡槽120，进而避免所述第二盖体20脱离所述第一盖体10。如图5C所示，在本发明又一实施方式中，所述卡槽120包括第一卡槽部1201和连通所述第一卡槽部1201的第二卡槽部1202。所述第一卡槽部1201和所述第二卡槽部1202均相较于所述第一盖板11所在平面呈倾斜设置且倾斜方向相反。例如，可以使得所述卡槽120大致呈现V字形。所述卡扣220用于通过所述第一卡槽部1201滑动至所述第二卡槽部1202中。由于所述卡扣220能够容置于所述第二卡槽部1202中，同样可以防止所述卡扣220滑出所述卡槽120，进而避免所述第二盖体20脱离所述第一盖体10。
如图5A所示，在本发明的一些实施例中，所述第一侧壁12的外侧连接有卡槽板13，所述卡槽板13包括主体部131和连接于所述主体部131两侧的连接部132，所述连接部132固定于所述第一侧壁12的外侧，所述主体部131与所述第一侧壁12相距设置，所述主体部131包括远离所述第一盖板11的侧边1310，所述卡槽120由所述侧边1310向所述主体部131内开设。
所述卡扣220的长度可大于所述卡槽120的深度(即，所述主体部131的厚度)，且小于所述主体部131与连接对应的卡槽板13的第一侧壁12之间的距离。
进一步地，所述卡扣220的直径可以设置为0.05-1mm。所述卡扣220的直径略小于所述卡槽120的宽度，使得所述卡扣220可在所述卡槽120中滑动，降低了安装难度。
更进一步地，所述连接部132可通过螺栓连接、铆接或焊接的方式固定于所述第一侧壁12。在本实施方式中，所述连接部132通过螺栓连接的方式固定于所述第一侧壁12。具体地，如图5A所示，所述连接部132上开设有第一固定孔1320，所述第一侧壁12对应于所述第一固定孔1320的位置也开设有第二固定孔(图未示)，螺栓可穿过所述第一固定孔1320以及所述第二固 定孔，以将所述连接部132固定于所述第一侧壁12。由于所述第一盖体10和所述第二盖体20完成安装后，所述螺栓会被所述第二盖体20覆盖，从而避免所述螺栓对所述箱体1的外观造成影响。
在本发明的一些实施例中，所述卡槽120在所述侧边1310上形成第三开口121，所述第三开口121的宽度大于所述卡扣220的宽度，所述卡槽120还包括与所述第三开口121相对设置的端部122，当所述卡扣220位于所述端部122时，所述第一密封圈40的压缩量大于或等于50％。此时所述第一密封圈40可实现所述第一盖体10与所述第二盖体20之间较好的密封效果，从而隔绝外部水分、灰尘等异物进入所述箱体1。
如图4所示，在本发明的一些实施例中，所述第一侧壁12远离所述第一盖板11的边缘向外延伸形成凸缘123，所述凸缘123自所述第一侧壁12延伸出来的宽度小于所述主体部131与所述第一侧壁12之间的距离，所述第一密封圈40设置于所述第二盖板21与所述凸缘123之间。
如图3所示，在本发明的一些实施例中，所述箱体1还包括第三盖体30，所述第一盖体10包括与所述第一盖板11相对的第一开口14以及与所述第一侧壁12相对的第二开口15，所述第二开口15连接所述第一开口14，所述第二盖体20用于盖合于所述第一开口14，所述第三盖体30用于盖合于所述第二开口15并将所述第一盖体10固定至所述第二盖体20，从而提高所述箱体1的结构稳定性和抗震性能。
请一并参阅图7，在本发明的一些实施例中，所述第三盖体30包括第三盖板31和设置于所述第三盖板31边缘的第三侧壁32，所述第三盖板31对应所述第二开口15，所述第三侧壁32包围所述第一盖体10和所述第二盖体20。
在本发明的一些实施例中，所述第一盖体10还包括由所述第一侧壁12的边缘延伸形成且位于所述第二开口15中的延伸部16，所述第三盖板31与所述延伸部16通过紧固件(如：螺钉、螺栓等)固定。具体地，所述延伸部16上开设有第三固定孔160，所述第一盖板31在对应所述第三固定孔160的位置开设有第四固定孔(图未标)，紧固件可穿过所述第四固定孔和所述第三固定孔160以将所述第三盖板31固定于所述延伸部16，从而实现第三盖体30与 所述第一盖体10之间的固定。
在本发明的一些实施例中，所述第三盖板31与所述第二侧壁22之间设有第二密封圈33(参图3)，当所述第三盖体30盖合于所述第二开口15时，所述第二密封圈33呈压缩状态。所述第二密封圈33用于在所述第三盖体30与所述第一盖体10之间实现较好的密封效果。
安装时，将所述第二盖体20放置于所述第一盖体10上，使得所述卡扣220对准所述第三开口121处。然后，按压所述第二盖体20，使得所述卡扣220沿所述卡槽120滑动，此时所述第一密封圈40被压缩。当所述卡扣220滑动至所述卡槽120的端部122时，所述第一密封圈40压缩量较大以实现较好的密封效果。然后，再将所述第三盖体30盖合于所述第一盖体10，此时所述第二密封圈33呈压缩状态以在所述第三盖体30与所述第一盖体10之间实现较好的密封效果。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
