Abstract

本实用新型涉及一种二挡合页,是由靠背连接棘板、铆合夹片、鸡爪、弹簧、铆钉、座拍连接板等部分组成。靠背连接棘板与座拍连接板通过铆合夹片及其上的铆钉、弹簧连接为一体,鸡爪通过铆钉连接于铆合夹片上。靠背连接棘板的右侧为牙板,牙板中有牙槽,鸡爪落于牙槽之中。靠背连接棘板与座拍连接板之间活动连接的夹角范围在α2-α1之间。本实用新型可以作为家具配件,特别是用在钢制沙发家具上,使用时能够进行沙发座拍与靠背角度之间的调节,可以实现使用的三种角度。利用棘板、铆合夹片、座拍连接板上设置的不同安装孔,可调整沙发不同的外型尺寸。

Description

二挡合页 
技术领域
本实用新型涉及沙发调整装置,具体涉及一种用于调整钢制沙发的座拍与靠背角度的二挡合页,属于国际专利分类B65N技术领域。 
背景技术
现有技术中的沙发,在规格、样式上已经有了不小的改进。但是,即使十分豪华的沙发,其靠背一般都是固定的,无法实现角度的调整。 
发明内容
本实用新型的目的,在于克服上述现有技术中的不足,提供一种可以实现沙发靠背角度调整的二挡合页。 
本实用新型的目的是通过以下技术方案实现的。 
一种二挡合页,包括靠背连接棘板、铆合夹片、鸡爪、弹簧、铆钉、座拍连接板等部分组成。靠背连接棘板与座拍连接板通过铆合夹片及其上的铆钉、弹簧连接为一体,鸡爪通过铆钉连接于铆合夹片上。 
所述靠背连接棘板的右侧为牙板,牙板中有牙槽,鸡爪落于牙槽之中。 
所述的靠背连接棘板与座拍连接板之间活动连接的夹角范围在α2-α1之间,具体是在105°-125°之间。 
本实用新型的二挡合页可以作为家具配件,特别是用在钢制沙发家具上,使用时能够进行沙发座拍与靠背角度之间的调节,可以实现使用的三种角度。利用棘板、铆合夹片、座拍连接板上设置的不同安装孔,可调整沙发不同的外型尺寸。

图中:1、靠背连接棘板,2、铆合夹片,3、鸡爪,4、弹簧,5、铆钉,6、座拍连接板,7、牙板,8、牙槽,9、牙顶。 
具体实施方式
参见上述各附图,作为家具配件的二挡合页,由靠背连接棘板1、铆合夹片2、鸡爪3、弹簧4、铆钉5、座拍连接板6等部分;靠背连接棘板1与座拍连接板6之间通过铆合夹片2及其上的铆钉5和弹簧4连接为一体。鸡爪3通过铆钉5连接于铆合夹片2上。靠背连接棘板1右侧为牙板7,牙板7中有牙槽8,鸡爪3落入不同的牙槽8中,以实现挡位变换。靠背连接棘板1与座拍连接板6之间活动连接的夹角范围在α2-α1之间,即在105°-125°之间。其中125°为最大限位倾角。 
在水平状态下,如图3所示,由于弹簧4的拉紧作用,鸡爪3处于不限位状态,座拍连接板6与靠背连接棘板1处于水平状态; 
一挡状态下,如图4所示,当外力沿顺时针方向转动靠背连接棘板1时,棘板的牙顶9在鸡爪3的顶部滑过,鸡爪3的顶部落入牙板7的牙槽8内,靠背连接棘板1不可以逆时针转动,形成限位角α1。 
二挡状态下,如图5所示,当沿顺时针方向继续转动靠背连接棘板1时,鸡爪3的顶部落入下一个牙槽8内,靠背连接棘板1与底座连接板6之间形成新的夹角α2。 
回位状态下,如图6所示,当沿顺时针方向继续转动靠背连接棘板1时,鸡爪3的顶部滑过靠背连接棘板1的右侧牙顶,没有了限位牙槽,鸡爪3的外圆弧面与靠背连接板1之牙板7的外侧面紧贴,鸡爪3的顶部没有了限位作用,靠背连接棘板1可以沿逆时针方向转动,回到水平状态位置。 
为提高强度,鸡爪在制作时使用玛钢铸件,靠背连接牙板则用Mn16板材制作。
