躺椅锁紧拉环结构及带有该躺椅锁紧拉环结构的躺椅
本技术涉及折叠躺椅领域,尤其涉及了躺椅锁紧拉环结构及带有该躺椅锁紧拉环结构的躺椅。
技术介绍
由于躺椅较传统的椅子更能让人放松,处于半睡的状态得到全身的放松和休息。所以被广泛应用于医院陪护椅、午休椅、户外休闲椅等。而折叠躺椅更由于其方便实用,折叠灵活,占用空间小,携带方便等特点,更是被广泛应用于旅行休闲,办公室午睡等方面。一些紧急自然灾害时,它还具有不可替代的快速安置灾民的作用。现有的很多躺椅调节靠背的倾斜度一般都在扶手处设置调节装置,而这些调节装置一般都在扶手杆下方设置齿条,扶手杆外设锁紧套,锁紧套内设有偏心轴旋钮,在偏心轴旋钮上方设置一带齿的锁紧块与扶手杆下方的齿条对应调节,这种调节装置在固定锁住扶手时偏心轴旋钮把锁紧块往上推使锁紧块的齿深入到扶手杆下方的齿条内来锁住扶手,当需再次调节扶手旋转偏心轴旋钮时,锁紧块会卡在齿条上不回落,以致无法调节扶手,需用手敲打扶手,使其回落,这种锁紧块与偏心轴旋钮分离式设计的扶手调节装置使用起来十分不便。中国专利号CN206 ...
