Description

一种沙发扶手连接结构及沙发组件 技术领域
本实用新型涉及家具技术领域，尤其涉及一种沙发扶手连接结构及沙发组件。
背景技术
目前，市面上的沙发扶手与主体之间通常采用螺栓或螺钉等紧固件直接进行连接。当沙发扶手为木质结构时，其与主体连接后便不能拆卸，容易造成搬动不便；当沙发扶手为金属或塑料结构时，则需要提前在沙发扶手上开设安装孔，较为麻烦，且对孔系的位置精度要求较高，安装完成后其位置不可调节，装配灵活性较低。
实用新型内容
为了克服上述现有技术所述的至少一种缺陷，本实用新型提供一种沙发扶手连接结构及沙发组件。
本实用新型为解决其问题所采用的技术方案是：
本实用新型第一方面提供一种沙发扶手连接结构，包括第一构件和第二构件，所述第一构件包括第一基板、对称设置在第一基板上的两导轨以及设置在第一基板上且位于两导轨下方的限位件；所述第二构件包括第二基板和对称设置在第二基板上的两导向条，两所述导向条分别与两所述导轨滑动插接配合；
所述第一基板和第二基板上均设有若干螺栓孔；
所述第一基板用于与沙发座框连接，所述第二基板用于与沙发扶手连 接；
或者，所述第一基板用于与沙发扶手连接，所述第二基板用于与沙发座框连接。
本实用新型的沙发扶手连接结构，将第二构件上的两导向条与第一构件上的两导轨滑动插接配合后，其固定的方式有两种，一种是通过第一构件上的限位件与两导向条相抵接，使第二构件的滑动受到限制，从而实现第一构件与第二构件之间的连接；另一种是将第一基板上的螺栓孔与第二基板上的螺栓孔相对准，再通过螺栓实现两者的连接。由此可知，采用该沙发扶手连接结构，不仅使得沙发扶手的安装与拆卸更加方便，同时还可以通过螺栓孔调节安装位置，大大提高了沙发扶手装配的灵活性。
进一步地，所述第一基板呈长条板状，所述导轨为第一基板的侧边朝向所述第一基板的一面弯折所形成的第一弯折结构；所述限位件为第一基板上靠近端部的一侧边朝向所述第一基板的一面弯折所形成的第二弯折结构；所述第一弯折结构与第二弯折结构均朝向所述第一基板的同一面弯折。
进一步地，两所述导轨之间的宽度沿第一基板的轴线方向逐渐减少。
由此，当两导向条插入两导轨内时，两者配合得更加紧固，进而提高了沙发扶手的装配牢固性。
进一步地，所述第二基板也呈长条板状，所述导向条为第二基板的侧边朝向所述第二基板的一面弯折所形成的第三弯折结构。
进一步地，所述第三弯折结构呈“ㄇ”型。
进一步地，两所述导向条之间的宽度沿第二基板的轴线方向逐渐减少。
由此，当两导向条插入两导轨内时，两者配合得更加紧固，进而提高了沙发扶手的装配牢固性。
本实用新型第二方面还提供一种沙发组件，包括如本实用新型第一方面提供的连接结构、沙发座框以及沙发扶手，其中：
所述沙发座框包括对称设置的两横梁以及连接两所述横梁的两纵梁； 所述纵梁包括第一承托板以及设置在所述第一承托板一侧的第一侧板；
所述第一基板与纵梁上的第一侧板连接，所述第二基板与沙发扶手连接；或者，所述第一基板与沙发扶手连接，所述第二基板与纵梁上的第一侧板连接。
综上所述，本实用新型提供的一种沙发扶手连接结构及沙发组件，不仅使得沙发扶手的安装与拆卸更加方便，同时还可以通过螺栓孔调节安装位置，大大提高了沙发扶手装配的灵活性。
