Description

一种可折叠式休闲椅 技术领域
本发明属于座椅技术领域，具体是指一种可折叠式休闲椅。
 背景技术
休闲椅是指我们平常享受闲暇时光用的椅子，这种椅子并不像餐椅和办公椅那样的正式，它能够给你视觉和身体的双重舒适感，目前市场上的休闲椅种类很多，有折叠椅、转椅、摇椅及躺椅等，休闲椅以其舒适的姿势，受到了越来越多的消费者的青睐，给人们的生活带来无限舒适。
 技术问题
然而现有的折叠椅虽然具备了折叠的功能，但是还是存在以下不足之处：1、椅子在折叠状态不便于锁定，在携带式，折叠的椅子容易张开，给携带带来诸多不便，2、椅子后背不便于调整角度，不能满足不同用户的使用需求，基于此，需要进行改进。
 技术解决方案
为了解决上述难题，本发明提供了一种能够对座椅的后背进行角度调整，同时能够对座椅的折叠与打开状态进行锁止固定的可折叠式休闲椅。

图2为图1中A处局部放大图；
图3为图1中B处局部放大图。
其中，1、支腿一，2、连杆，3、支腿二，4、座板，5、靠板，6、锁定装置，7、角度调节装置，8、转轴，9、蜗轮，10、蜗杆，11、摇把，12、齿轮，13、限位箱，14、锁止杆，15、弹簧，16、拉环，17、软垫，18、脚垫，19、键条。
 本发明的实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。以下结合附图，对本发明做进一步详细说明。
如图1-3，本发明一种可折叠式休闲椅，包括支腿一1、连杆2、支腿二3、座板4、靠板5、锁定装置6和角度调节装置7，连杆2铰接设于支腿一1上，支腿二3与连杆2二另一端铰接连接，座板4与支腿一1和支腿二3均铰接连接，靠板5铰接设于支腿一1上，锁定装置6设于支腿二3中且能够对连杆2进行锁定，角度调节装置7设于支腿一1种且能够对靠板5的角度进行调整；角度调节装置7包括转轴8、蜗轮9、蜗杆10和摇把11，转轴8与靠板5相连接且转动设于支腿一1内，蜗轮9与转轴8相连接，蜗杆10转动设于支腿一1内且与蜗轮9啮合连接，摇把11设于蜗杆10的另一端，通过转动蜗杆10，蜗杆10啮合蜗轮9旋转，蜗轮9带动转轴8旋转，从而实现了对靠板5的角度调整，用户使用起来比较灵活，提高了舒适性。
锁定装置6包括齿轮12、限位箱13、锁止杆14、弹簧15和拉环16，齿轮12与连杆2的一端相连接且同时转动于支腿二3内，限位箱13设于支腿二3内，锁止杆14贯穿限位箱13插接于齿轮12上，弹簧15套接设于锁止杆14上且位于限位箱13内，弹簧15的一端设于限位箱13上且另一端设于锁止杆14上，拉环16设于锁止杆14的另一端，通过拉动拉环16，锁止杆14可以从齿轮12上脱离，座椅可以进行折叠与打开，松开拉环16，锁止杆14可以扣入到齿轮12中，完成对连杆2的锁定，便于携带。
座板4和靠板5上均设有软垫17。
支腿一1和支腿二3上均设有脚垫18，脚垫18为橡胶材质制成。
蜗轮9内设有键条19，转轴8与蜗轮9采取键条19式连接，便于拆卸蜗轮9。
弹簧15始终对锁止杆14有一个扣向齿轮12方向的力。
具体使用时，需要调节靠板5的角度时，通过摇动摇把11，蜗杆10旋转，蜗杆10啮合蜗轮9旋转，蜗轮9会带动转轴8一起旋转，从而靠板5会随转轴8一起在支腿一1内旋转，直至靠板5的角度合适，停止摇动摇把11时，蜗杆10可以阻止蜗轮9旋转，达到对靠板5角度固定的目的，从而满足了不同用户的需求，需要折叠时，劳动拉环16，弹簧15被蓄力，锁止杆14从齿轮12上脱离，转动座板4和支腿二3，座板4向靠板5方向靠近支腿二3向支腿一1方向靠近，同时连杆2也会向靠板5方向旋转，直至座板4和支腿二3完全折叠后，松开拉环16，在弹簧15的作用下，锁止杆14会扣向齿轮12，完成对连杆2的固定，这样就保证了座板4和支腿二3不会随意打开，更便于用户携带，节省占用空间。
以上对本发明及其实施方式进行了描述，这种描述没有限制性，附图中所示的也只是本发明的实施方式之一，实际的结构并不局限于此。总而言之如果本领域的普通技术人员受其启示，在不脱离本发明创造宗旨的情况下，不经创造性的设计出与该技术方案相似的结构方式及实施例，均应属于本发明的保护范围。
