具体实施方式
为了更好地理解和实施，下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述。
除非另有定义，本文所使用的所有的技术和科学术语与属于本实用新型的技术领域的技术人员通常理解的含义相同。本文中在本实用新型的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本实用新型。
实施例一
参阅图1-2，本实用新型公开了一种沙发靠背连接结构1，包括第一构件11和第二构件12，该第一构件11包括第一基板111、对称设置在第一基板111上的两导轨112以及设置在第一基板111上且位于两导轨112上方的限位件113，该限位件113设有卡接凸起1132；该第二构件12包括第二基板121以及连接该第二基板121的第一横板122，该第二基板121包括插入部1211，该插入部1211上设有与卡接凸起1132相配合的卡位孔12111；该插入部1211沿两导轨112滑动插接配合后，该卡接凸起1132卡设于卡位孔12111内。
其中，该第一横板122用于与沙发座框2连接，该第一基板111用于与沙发靠背3连接。
具体的，该第一基板111呈长条板状，该导轨112为第一基板111的侧边朝向第一基板111的一面弯折所形成的第一弯折结构；该限位件113包括第一基板111的顶边朝向第一基板111的一面弯折所形成的第二弯折结构1131；该第一弯折结构与第二弯折结构1131均朝向第一基板111的同一面弯折。该卡接凸起1132连接于第二弯折结构1131。
在本实施例中，该第一弯折结构和第二弯折结构1131均为二次弯折，且呈L型；诚然，在其他实施例中，该第一弯折结构和第二弯折结构1131也可以为其它形状；与此同时，该第一弯折结构和第二弯折结构1131可以不限于一体弯折成型结构，还可以通过焊接的方法将其与第一基板111进行固定。该卡接凸起1132具有一竖直面和一斜面，该斜面可便于卡接凸起1132滑进卡位孔12111，该竖直面可保证卡接凸起1132不易脱离该卡位孔12111。该卡位孔12111为通孔。
另外，参阅图2，该限位件113上还设有解锁拨片1133，该解锁拨片1133连接于卡接凸起1132的末端。在本实施例中，该解锁拨片1133为一倾斜块，且朝向远离第一基板111的方向倾斜，从而方便用户进行拨动解 锁。
由此，通过外力作用于该解锁拨片1133上，使卡接凸起1132从卡位孔12111内滑出，即可实现第一构件11和第二构件12的脱离。
再参阅图1-2，两导轨112之间的宽度沿第一基板111的轴线方向逐渐减小，从而大致呈梯形状。在本实施例中，该第二基板121为一大致呈三角状的直板，该插入部1211为第二基板121的上部部分，也大致呈三角状，以使该插入部1211刚好卡接于两导轨112内。另外，该插入部1211的末端两侧还设有两限位孔12112，当插入部1211插入两导轨112内时，两导轨112可与两限位孔12112相抵接，从而实现两者的紧固配合，进而提高了沙发靠背3装配的稳定性。
在本实施例中，该第二基板121与第一横板122一体弯折成型，且呈L型。由此，一体弯折成型的第二构件12的支撑强度更高，且方便加工。诚然，在其他实施例中，该第二基板121与第一横板122也可以通过焊接方式进行固定。
实施例二
参阅图3-4，本实用新型还提供一种沙发组件，包括实施例一中的沙发靠背连接结构1、沙发座框2以及沙发靠背3，该沙发座框2包括对称设置的两横梁21以及连接两横梁21的两纵梁22。
在本实施例中，该第一横板122与纵梁22的上表面连接，该第一基板111与沙发靠背3连接。具体的，该第一横板122与纵梁22，该第一基板111与沙发靠背3之间均通过螺栓连接的方式固定。
综上所述，本实用新型提供的一种沙发靠背连接结构1及沙发组件，不仅可以实现沙发靠背3与沙发主体之间的牢固连接，同时使得沙发靠背3的安装与拆卸更加方便，进而提高了沙发组件的安装与拆卸效率。
本实用新型方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出， 对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本实用新型的保护范围。
