本发明通过以下技术方案来实现上述目的,一种易安装的铝蜂窝板,包括铝基板、粘板和蜂窝板,所述粘板和蜂窝板可拆卸的安装在所述铝基板上下两个板面上,所述铝基板上还设置有安装板和钳板,通过安装板和钳板的组合进行多组复合板的组装,所述铝基板与粘板之间设置有多个气囊条和泡沫隔层,通过管路相通的气囊条使粘板与铝基板之间弹性连接,以增强板体的减震性能。
作为本发明的一种技术优化方案,所述铝基板中部设置有放置槽,放置槽内填装有药剂挥发棉,通过填装药剂挥发棉,使板材能够起到驱霉、净化的作用,挥发棉内可填充各种干燥剂、清新剂等药剂。
作为本发明的一种技术优化方案,所述钳板分为固定结构的基板和活动夹板,基板和活动夹板平行安装在铝基板两侧,并构成钳口状结构,钳口的尺寸与所述安装板相配合,通过钳板将安装板钳夹固定。
作为本发明的一种技术优化方案,所述活动夹板与所述铝基板之间安装有杆状的弹簧轴,且所述活动夹板通过所述弹簧轴与所述铝基板侧边转动连接,使钳口能够张开,方便安装板的填装。
作为本发明的一种技术优化方案,所述弹簧轴上设置有推板,当所述活动夹板平行于所述基板时,所述推板与活动夹板角度垂直,使活动夹板收起,从而方便安装板的稳定钳装。
作为本发明的一种技术优化方案,所述粘板上设置有若干个凹槽,通过凹槽方便线路的布置。
作为本发明的一种技术优化方案,所述安装板和所述钳板上配套设置有若干个卡件和线路孔,通过卡件将安装板与钳板卡紧,并通过线路孔将所需要布置的线路伸出板面。
作为本发明的一种技术优化方案,所述铝基板和粘板及蜂窝板之间均设置有安装扣件,并通过安装扣件对粘板和蜂窝板卡装固定,使板面的安装更加方便,并便于药剂挥发棉的更换。
本发明的有益效果是:本装置将通过多层组合的方式,便于单体板材的安装的拆卸,通过安装板、钳板以及连接件的设置,便于多组复合板的组装,粘板和铝基板之间设置有气囊条和泡沫隔层,从而增强板材整体的减震效果,安装板和钳板之间的组装方式为嵌入式锁紧结构,安装操作简便,药剂挥发棉可以通过拆卸蜂窝板进行更换,节省了人力损耗。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
实施例1
请参阅图1-5所示,一种易安装的铝蜂窝板,包括铝基板、粘板和蜂窝板,粘板和蜂窝板可拆卸的安装在铝基板上下两个板面上,铝基板上还设置有安装板和钳板,通过安装板和钳板的组合进行多组复合板的组装,铝基板与粘板之间设置有多个气囊条和泡沫隔层,通过管路相通的气囊条使粘板与铝基板之间弹性连接,以增强板体的减震性能,铝基板中部设置有放置槽,放置槽内填装有药剂挥发棉;钳板分为固定结构的基板和活动夹板,基板和活动夹板平行安装在铝基板两侧,并构成钳口状结构,钳口的尺寸与安装板相配合;活动夹板与铝基板之间安装有杆状的弹簧轴,且活动夹板通过弹簧轴与铝基板侧边转动连接;弹簧轴上设置有推板,当活动夹板平行于基板时,推板与活动夹板角度垂直;粘板上设置有若干个凹槽;安装板和钳板上配套设置有若干个卡件和线路孔;铝基板和粘板及蜂窝板之间均设置有安装扣件,并通过安装扣件对粘板和蜂窝板卡装固定。
本发明在使用时,首先,将铝基板1整体通过粘板2粘附在指定的车厢板壁上,向药剂挥发棉6内充入清新剂或者干燥剂后,填装入放置槽101内,通过安装扣件将蜂窝板3与铝基板1组合安装,形成安装的复合板板体,通过铝基板1两侧的安装板4和钳板5组合,将多组复合板组装,铝复合板1另外两侧也安装有配合的连接件,便于复合板的组装,在安装板4填入钳板5的钳口时,安装板4会向内顶住推板503转动,从而带动多节的弹簧轴502纵向转动,与此同时,活动夹板501会跟随着弹簧轴502转动,从而使活动夹板501靠近基板位置,并通过活动夹板501和安装板4上共同设置的的卡件66将安装板4锁紧在钳板5内,在列车晃动时或者乘客不小心挤压时,粘板2与铝基板1之间的气囊条7和泡沫隔层8对粘板2和铝基板1之间的组装结构进行减震缓冲,保持装置结构的稳定性,在列车单次形成结束后,工作人员可通过打开安装扣件,并选择合适的复合板间距,拆卸蜂窝板2,并更换放置槽101内的药剂挥发棉6。
此外,应当理解,虽然本说明书按照实施方式加以描述,但并非每个实施方式仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经适当组合,形成本领域技术人员可以理解的其他实施方式。
