实施例一
参见图1至图8，本实用新型实施例提供一种充气床，包括由外围片11、顶片12和底片13围成的气室，顶片12的边缘与外围片11的上边缘连接，底片13的边缘与外围片11的下边缘连接，还包括至少一个进出气部件3，进出气部件3与气室连通，能够向气室内充放气。
充气床还包括至少一个拉带2，拉带2设置于气室内，拉带2与气室的内壁之间不完全密封连接，每个拉带2的至少部分边缘与气室的内壁之间断开形成至少一个通气口20。通过拉带2与气室的内壁连接，增加充气床的强度，便于更好地提供支撑力；通气口20的设置，无需在拉带2上设置通气孔，便于进行充放气，通气口20利用拉带2的边缘形成，简化了加工工序，避免了开设通气孔导致的撕裂问题。
对于一个拉带2来说，大部分边缘与气室的内壁连接，有小部分边缘与气室的内壁之间断开形成通气口20。一个拉带2的边缘上可以形成一个、两个或者两个以上的通气口20，在此对通气口20的大小和数量均不作限制。

在本实施例中，拉带2呈矩形，当然，可以根据实际需要设置拉带2的形状，只要保证拉带2有部分边缘与气室的内壁之间断开即可。
拉带2设置有至少两个，至少一个拉带2为上拉带21，上拉带21的一侧连接外围片11的内侧，上拉带21的另一侧连接顶片12的内侧，至少一个拉带2为下拉带22，下拉带22的一侧连接外围片11的内侧，下拉带22的另一侧连接底片13的内侧。上拉带21与下拉带22的设置，保证外围片11受力的均匀性，上拉带21与下拉带22同时对外围片11提供向内的拉力，防止外围片11向外过度变形，以便于更均匀地提供支撑力。
上拉带21的下边缘与外围片11连接，下拉带22的上边缘与外围片11连接，上拉带21的下边缘与外围片11的连接处不低于下拉带22的上边缘与外围片11的连接处，避免上拉带21与下拉带22之间干涉，也使得外围片11受力均衡。
当上拉带21设置有一个时，一个上拉带21可以绕气室的周向形成连续的环形结构，在上拉带21与顶片12的连接处和/或在上拉带21与外围片11的连接处有部分边缘与气室的内壁之间断开，形成通气口20即可。当然，一个上拉带21也可以绕气室的周向形成间断的环形结构，在上拉带21的间断处，上拉带21与气室的内壁之间断开以便于通气。
上拉带21设置有至少两个，至少两个上拉带21绕气室的周向形成间断的环形结构。在相邻两个上拉带21的间断处，上拉带21与气室的内壁之间断开，以形成通气口20。
当下拉带22设置有一个时，一个下拉带22可以绕气室的周向形成连续的环形结构，在下拉带22与底片13的连接处和/或在下拉带22与外围片11的连接处有部分边缘与气室的内壁之间断开，形成通气口20即可。一个下拉带22可以绕气室的周向形成间断的环形结构，在下拉带22的间断处，下拉带22与气室的内壁之间断开以形成通气口20便于通气。
下拉带22设置有至少两个，至少两个下拉带22绕气室的周向形成间断的环形结构。在相邻两个下拉带22的间断处，下拉带22与气室的内壁之间断开，以形成通气口20。
当顶片12和底片13均呈矩形时，外围片11具有四个内侧壁，可以在每个内侧壁上均设置有上拉带21和下拉带22，即设置有四个上拉带21和四个下拉带22，四个上拉带21绕气室的周向形成间断的环形结构，四个下拉带22绕气 室的周向形成间断的环形结构，便于加工生产。当然，当充气床为其他形状时，可根据需要设置上拉带21和下拉带22的数量，在此不作限制。
在本实施例中，上下相对设置的一组上拉带21与下拉带22，上拉带21的下边缘与外围片11的连接处不低于下拉带22的上边缘与外围片11的连接处，避免上拉带21与下拉带22之间干涉，也使得外围片11受力均衡。
气室内设置有至少一个支撑部4，支撑部4的顶端与顶片12连接，支撑部4的底端与底片13连接，以起到支撑作用，提高支撑力。
可选地，支撑部4设置有至少两个，至少两个支撑部4并排设置于气室中，使得充气床中间部位的受力被分摊，相邻支撑部4之间是有间隔的，便于气体填充。
支撑部4的设置，不影响气室内的充气空间，支撑部4为圆柱体或者片状，在此不作限制。
在此，对充气床的材料不作限制，可采用PVC、PU、PE等现有的轻质塑料制成。充气床中各个部件之间的连接方式，可以是高周波焊接，热熔或者超声波熔接，在此不作限制。
通过一个进出气部件3即可实现对充气床的充气和放气，进出气部件3可以是进出气阀，通过外置的气泵与进出气阀连接进行充气。进出气部件3还可以是内置气泵，内置气泵中设置有气阀，能够进行充气和放气。当然，进出气部件3还可以是进出气阀与内置气泵的组合。在此对进出气部件3的设置位置不作限制，一般设置于外围片11上。当然，为了提高进气和放气的效率，可以设置两个甚至两个以上的进出气部件3，在此不再赘述。
实施例二
图9示出了实施例二，其中与实施例一相同或相应的零部件采用与实施例 一相应的附图标记。为简便起见，仅描述实施例二与实施例一的区别点。区别之处在于，上拉带21设置有至少两个，至少两个上拉带21于气室内平行设置，即将上拉带21设置有多层，进一步增加充气床的支撑强度。
在本实施例中，外围片11具有四个内侧壁，每个内侧壁上均设置有两条上拉带21，即设置有八个上拉带21，位于同一个内侧壁上的两个上拉带21相互平行，一个上拉带21位于另一个上拉带21与气室的内壁之间。通过上拉带21的部分边缘与气室的内壁之间断开以形成通气口20。当然，当充气床为其他形状时，可根据需要设置上拉带21的数量，在此不作限制。
下拉带22设置有至少两个，至少两个下拉带22于气室内平行设置，即将下拉带22设置有多层，进一步增加充气床的支撑强度。
在本实施例中，外围片11具有四个内侧壁，每个内侧壁上均设置有两条下拉带22，即设置有八个下拉带22，位于同一个内侧壁上的两个下拉带22相互平行，一个下拉带22位于另一个下拉带22与气室的内壁之间。通过下拉带22的部分边缘与气室的内壁之间断开以形成通气口20。当然，当充气床为其他形状时，可根据需要设置下拉带22的数量，在此不作限制。
以上实施方式只是阐述了本实用新型的基本原理和特性，本实用新型不受上述实施方式限制，在不脱离本实用新型精神和范围的前提下，本实用新型还有各种变化和改变，这些变化和改变都落入要求保护的本实用新型范围内。本实用新型要求保护范围由所附的权利要求书及其等效物界定。
