Description

一种折叠帐篷用下拉式解拉杆锁装置
本申请要求于2019年12月10日提交中国专利局、申请号为201922199444.3、申请名称为“一种折叠帐篷用下拉式解拉杆锁装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及折叠篷领域，尤其涉及一种折叠帐篷用下拉式解拉杆锁装置。
背景技术
折叠帐篷在使用时可以展开，在不使用时可以折叠收合，具有遮阳挡雨，并且携带方便的优点，从而在日常生活中广泛应用。
目前实现该类折叠帐篷的收合过程还比较复杂，步骤繁多，而且帐篷尺寸大，一般单人不容易操作，需两人或者更多的人员才能较为省力的完成收合。帐篷展开时需由人员多处锁死，同样在帐篷收合时需由人员在多处锁死处解锁，这就导致了使用过程中的不简便。
发明内容
本发明的目的在于，解决现有技术中存在的上述不足之处。
为实现上述目的，本发明提供一种折叠帐篷用下拉式解拉杆锁装置，包括活动件底座、锁舌支撑片、2个对称设置的锁舌片、活动件上盖和拉杆；活动件底座和活动件上盖通过紧固件、弹簧连接，组成活动腔；锁舌支撑片通过固定在活动件上盖上，锁舌支撑片和活动件上盖之间设置有滑动槽，2个锁舌片可滑动的设置在滑动槽内；每个锁舌片包括锁舌片本体、设置在锁舌片本体一侧的锁柱和设置在锁舌片本体下方的立柱，立柱穿过锁舌支撑片，立柱的底端设置有锁舌片斜面，锁舌片本体的另一侧设置有半漏斗式凹槽，锁柱穿过一个锁舌片复位弹簧，锁舌片复位弹簧的另一端抵顶在活动件上盖的内侧；活动件底座的中部设置有中心柱，中心柱包括中心柱本体和设置在中心柱本体顶端的收容腔，拉杆的底端的拉杆凸起卡在收容腔内，其中，收容腔的直径大于中心柱本体，收容腔的外表面设置有延伸到中心柱本体的中心 柱斜面，中心柱斜面与锁舌片斜面滑动配合，收容腔设置在锁舌片本体下方，收容腔位于2个立柱之间；在向下的拉力作用下，中心柱斜面沿着锁舌片斜面相对滑动，产生对两个锁舌片施加向两端的作用力，克服锁舌片复位弹簧的作用，将两个锁舌片向外推动，两个锁舌片本体分离，拉杆底端的拉杆凸起脱离锁舌片，实现解锁。
在一个可能的实施方式中，锁舌支撑片中心设置有贯穿孔，贯穿孔两侧对称地设置有第一滑槽，活动件上盖设置有与贯穿孔位置对应的第二滑槽，以及与第一滑槽对应的第三滑槽，立柱穿过贯穿孔，锁柱可滑动地卡在第一滑槽内和第三滑槽内，锁舌片本体可滑动地卡在第二滑槽内。
在一个可能的实施方式中，锁舌支撑片通过紧固件固定在活动件上盖上。
在一个可能的实施方式中，紧固件为螺丝。
在一个可能的实施方式中，拉杆的顶端还连接有顶盖。
本发明可以直接在下拉的过程中实现解锁，操作简单，一步到位。

具体实施方式
本发明的说明书实施例和权利要求书及附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下面结合附图和实施例，对本发明的技术方案做进一步的详细描述。
如图1-17，本发明实施例提供一种折叠帐篷用下拉式解拉杆锁装置，包括活动件底座10、锁舌支撑片8、2个对称设置的锁舌片6、活动件上盖5、拉杆2和顶盖1。
活动件底座10和活动件上盖5通过第一螺丝3、弹簧4连接，组成活动腔，弹簧4的作用是复位活动件底座10，如果没有该弹簧，活动件底座10会因为重力作用处于下垂状态，有了弹簧4，会拉紧活动件底座10。
锁舌支撑片8通过第二螺丝9固定在活动件上盖5上，锁舌支撑片8和活动件上盖5之间设置有滑动槽，2个锁舌片6可滑动的设置在所述滑动槽内。
如图7-9，每个锁舌片6包括锁舌片本体61、设置在锁舌片本体61一侧的锁柱62和设置在锁舌片本体61下方的立柱63，立柱63穿过所述锁舌支撑片8，立柱63的底端设置有锁舌片斜面64，锁舌片本体61的另一侧设置有半漏斗式凹槽611，半漏斗式凹槽611起到拉杆2插进来时的导向作用，可使拉杆2插进来时有单向而且漏斗的斜坡更利于挤开锁舌片本体61让拉杆2通过锁舌片本体61，如图4，锁柱62穿过一个锁舌片复位弹簧7，锁舌片复位弹簧7的另一端抵顶在活动件上盖5的内侧。
如图5-6，活动件底座10的中部设置有中心柱101，中心柱101包括中心柱本体1011和设置在中心柱本体1011顶端的收容腔1012，拉杆2的底端的拉杆凸起21卡在收容腔1012内，其中，收容腔1012的直径大于中心柱本体1011，收容腔1012的外表面设置有延伸到中心柱本体1011的中心柱斜面1013，中心柱斜面1013与锁舌片斜面64滑动配合。收容腔1012设置在锁舌片本体61下方，2个立柱63之间。
具体地，如图3、图7、图8、图9和图10，锁舌支撑片8中心设置有贯穿孔81，贯穿孔81两侧对称地设置有第一滑槽82，活动件上盖5设置有与贯穿孔位置对应的第二滑槽51，以及与第一滑槽82对应的第三滑槽53，锁舌片6的立柱63穿过贯穿孔81，锁柱62可滑动地卡在第一滑槽82内和第三滑槽53内，锁舌片本体61可滑动地卡在第二滑槽51内。
使用方法：
如图11、图12和图16,在两端的锁舌片复位弹簧7向内的作用力下，2个对称布设的锁舌片6之间的半漏斗式凹槽611拼接成一个漏斗，拉杆2底 端的拉杆凸起21卡在漏斗下方的收容腔1012内，由于锁舌片复位弹簧7的存在，拉杆2底端的凸起21被锁舌片6锁在锁舌片本体61下方，拉杆2的实现锁紧。
如图13、图14和图17，向下拉动活动件底座10，中心柱斜面1013沿着锁舌片斜面64相对滑动，对两个锁舌片6施加向两端的作用力，克服锁舌片复位弹簧7的作用，将两个锁舌片6向外推动，两个锁舌片本体61分离，拉杆2底端的凸起即可脱离锁舌片6，实现解锁。
以上所述的具体实施方式，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施方式而已，并不用于限定本发明的保护范围，凡在本发明的技术方案的基础之上，所做的任何修改、改进等，均应包括在本发明的保护范围之内。
