Description

一种靠背可调节椅子
技术领域
本实用新型涉及家具领域,尤其涉及的是一种靠背可调节椅子。 
背景技术
随着电脑的普及和人们工作量的不断增大,久坐人群越来越多,然而传统椅子的椅座和靠背之间的角度通常是固定的,使用者的坐姿调整方式非常有限,极易产生疲劳,容易诱发腰椎、颈椎等疾病。 
现有的靠背调节装置以针对车载固定座椅设计的居多,靠背和椅座之间通过弹性连接装置连接,依靠人体对靠背施加以个向后的力,使靠背椅座之间产生弹性变形,以达到调整靠背仰角的目的,但是这种结构要求弹性连接装置具有很高的支撑强度和稳定性,对材料和生产工艺的要求都比较高,不适于在普通办公或者家用椅子中推广。 
实用新型内容
本实用新型的目的在于解决上述技术问题,提供一种结构简单、易于加工的靠背可调节椅子,使用者可以根据自身需要来调整靠背与椅座之间的夹角,以获得舒适的坐姿。 
为实现上述目的,本实用新型的技术解决方案是:一种靠背可调节椅子,包括椅座、靠背和底部支架,底部支架包括有前部支架和后部支架,前部支架和后部支架通过椅座两端的横架连接,所述靠背的两侧分别固定有支撑杆,所述两支撑杆同轴铰接在横架上,所述靠背后侧的两端铰接有卡槽框,卡槽框上设有一系列卡槽,所述两横架末端之间设有卡槽定位杆。 
优选的,所述两前部支架、后部支架与横架之间还设有固定杆。 
优选的,所述卡槽框为长方形。 
优选的,所述卡槽为锯齿形。 
优选的,所述椅座的两端设有与底部支架成一体的扶手。 
通过采用上述的技术方案,本实用新型的有益效果是:本实用新型通过卡槽定位杆将卡槽卡在合适的位置,从而将靠背锁定在所需的位置,由此达到变化靠背与椅座之间夹角的目的,具有结构简单、便于加工、成本低等优点。 
附图说明
图1为本实用新型一种靠背可调节椅子的结构示意图。 
具体实施方式
以下结合附图和具体实施例来进一步说明本实用新型。 
如图1所示,本实用新型的一种靠背可调节椅子,包括椅座1、靠背2和底部支架3,椅座1的两端设有与底部支架3成一体的扶手7,底部支架3包括有前部支架31和后部支架32,前部支架31和后部支架32通过椅座1两端的横架33连接,所述两前部支架31、后部支架32与横架33之间还设有固定杆34,通过固定杆34固定前部支架31、后部支架32,所述靠背2的两侧分别固定有支撑杆5,所述两支撑杆5同轴铰接在横架33上,所述靠背2后侧的两端铰接有长方形卡槽框21,卡槽框21上设有一系列锯齿形卡槽211,所述两横架33末端之间设有卡槽定位杆6,锯齿形卡槽211卡于卡槽定位杆6上,不同的锯齿形卡槽211的卡位对应不同的靠背2仰角,从而实现调整靠背2与椅座1之间夹角的目的。 
以上所述的 ,仅为本实用新型的一较佳实施例而已,不能限定本实用新型实施的范围,凡是依本实用新型申请专利范围所作的均等变化与装饰,皆应仍属于本实用新型涵盖的范围内。
