具体实施方式
下面详细描述本实用新型的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本实用新型，而不能理解为对本实用新型的限制。
实施例一
如图2至图4所示，本实用新型揭示的一种连接件1，包括安装面11、分别位于安装面11两侧的第一斜面12和第二斜面13、与安装面11相对设置的连接面14；第一斜面12和第二斜面13由安装面11延伸至连接面14，第一斜面12与第二斜面13之间的距离由安装面11至连接面14逐渐增大。
在使用该连接件1时，将两连接件1并排固定于承载件(如沙发部件)上，其中第一连接件1a的第二斜面13与第二连接件1b的第一斜面12之间形成插槽121，该插槽121由连接面14至安装面11宽度逐渐增大，即外窄内宽，该插槽121的宽度与固定于另一承载 件上的第三连接件1c的宽度基本相匹配，第三连接件1c由连接面14至安装面11宽度逐渐减小，即外宽内窄，第三连接件1c刚好插入插槽121形成连接。因此，通过对连接件1进行组合使用，以使连接方便，装配简单，且只需对应连接件1的一个模具，使得生产成本较低。
可选地，第一斜面12与第二斜面13轴对称设置。如此，使得在装配时，其中第一连接件1a的第一斜面12与第二连接件1b的第二斜面13接触良好，即接触面积大，从而使得连接牢固可靠。
为了方便将第三连接件1c插入两连接件1之间形成插槽121中，该连接件1还可以设置第一弧形面15和第二弧形面16，第一弧形面15分别连接第一斜面12和第二斜面13、安装面11、连接面14的一侧，第二弧形面16分别连接第一斜面12和第二斜面13、安装面11、连接面14的另一侧。如此，在第三连接件1c插入两连接件1之间形成插槽121时，第三连接件1c的第二弧形面16可以在抵靠在第一连接件1a的第一弧形面15或者第二连接件1b的第一弧形面15上，以方便第三连接件1c滑入两连接件1之间形成插槽121中，使得安装快速且方便。
作为一个示例，连接件1可以设置为长条状，当然，连接件1也可以为其他形状，此处不做限定。为了方便将连接件1固定于承载件上，可以在连接件1的安装面11上设有安装孔111，可以通过螺丝穿过安装孔111而将连接件1牢固连接于承载件上。
实施例二
如图4所示，本实施例揭示的一种连接组件2，包括至少三个上述连接件1；其中第一连接件1a、第二连接件1b并排固定于承载件上，第一连接件1a、第二连接件1b的安装面11抵靠于承载件上；第一连接件1a的第二斜面13与第二连接件1b的第一斜面12之间形成插槽121；第三连接件1c固定于另一承载件上，第三连接件1c的安装面11抵靠于另一承载件上，第三连接件1c插入插槽121时形成连接。
第一连接件1a的第二斜面13与第二连接件1b的第一斜面12之间形成插槽121，该插槽121的宽度由连接面14至安装面11逐渐增大，即外窄内宽，该插槽121的宽度与固定于另一承载件上的第三连接件1c的宽度基本相匹配，第三连接件1c由连接面14至安装面11宽度逐渐减小，即外宽内窄，第三连接件1c刚好插入插槽121形成连接。因此，使得连接方便，装配简单，且只需对应连接件的一个模具，使得生产成本较低。
上述实施例只是列举了两个连接件并排设置，第三连接件插入该两连接件之间形成的插槽中，当然，可以根据该连接组件模式，推演出其它的组合模式，如三个连接并排设置并形成两个插槽，每一插槽中分别插入连接件等等，以及推演出其它更多的组合模式，此处不赘述。
实施例三
如图5a至图7b所示，本实施例揭示的一种沙发3，包括上述连接组件2，通过上述连接组件2连接沙发部件。
第一连接件1a的第二斜面13与第二连接件1b的第一斜面12之间形成插槽121，该插槽121的宽度由连接面14至安装面11逐渐增大，即外窄内宽，该插槽121的宽度与固定于另一承载件上的第三连接件1c的宽度基本相匹配，第三连接件1c由连接面14至安装面11宽度逐渐减小，即外宽内窄，第三连接件1c刚好插入插槽121形成连接。因此，使得连接方便，装配简单，且只需对应连接件的一个模具，使得生产成本较低。
可选地，如图5a和图5b所示，沙发部件包括框架31和扶手32，框架31与扶手32之间可以设置连接组件2，以便于将扶手32安装于框架31上。
如图6a和图6b所示，沙发部件包括框架31和靠背33，框架31与靠背33之间可以设置连接组件2，以便于将靠背33安装于框架31上。
如图7a和图7b所示，沙发部件包括若干个框架31，框架31与框架31之间设置连接组件2，以便于框架31与框架31之间的连接。
当然，也可以框架31与扶手32之间、框架31与靠背33之间、框架31与框架31之间同时设置连接组件2等等。另外，可以将坐垫34放置框架31上，将靠垫35放置靠背33上，如此，使得人们坐在沙发3上时较为舒适。
