具体实施方式
以下结合说明书附图来进一步说明本发明。
实施例1
如图1所示，一种具有伸缩腿管便捷锁紧机构的帐篷包括帐篷顶架1以及连接在帐篷顶架1下方的支撑腿2。帐篷顶架1可以为现有技术中任何一种帐篷顶架。支撑腿2包括固定腿管201、能够在固定腿管201内上下活动的活动腿管202以及限定活动腿管202活动的锁紧机构。其中固定腿管201和活动腿管202可以为圆管，也可以为方管，也可以为现有技术中常用形状的腿管结构。
如图2-5所示，锁紧机构包括可活动设置在固定腿管201上并能够相对活动腿管202前后移动的锁紧按板204以及能够与锁紧按板204联动将活动腿管202锁紧的锁紧件206。
锁紧按板204和锁紧件206具体可以通过安装座203实现安装配合。安装座203包括了上下扣合分体的上安装座2031和下安装座2032。当然，上安装座2031和下安装座2032也可以为一体结构。安装座203中部具有通孔，固定腿管201穿过通孔将安装座203固定在固定腿管201下端口处。上安装座2031和下 安装座2032之间具有锁紧按板204和锁紧件206的安装腔。
安装座203上设有行程孔2033，即该行程孔2033具有一定的长度，常见的如跑道环形孔等。采用上述结构的行程孔2033，方便设置在其内的轴沿行程孔2033长度进行移动。
行程孔2033中通过设置的轴205连接锁紧按板204，轴205可以为独立的销轴，也可以为设置在锁紧按板204两端的凸轴，锁紧按板204通过旋转实现轴205在行程孔2033中移动，从而实现锁紧按板204相对与活动腿管202的前后移动。作为优选结构，锁紧按板204靠近活动腿管202一侧设有向活动腿管202处延伸的抵脚2042，抵脚2042上设有按板轴孔2044，按板轴孔2044中设有轴205，在锁紧状态下，该抵脚2042与安装座203或固定腿管201相抵使轴205移位至行程孔2033远离活动腿管202端，在解锁状态下，该抵脚2042与安装座203或固定腿管201分离使轴205移位至行程孔203靠近活动腿管202端。作为更优选结构，抵脚2042设置一对，分别在锁紧按板204靠近活动腿管202一侧的两端。为了锁紧按板204转动轻松，在抵脚2042上设置弧形导向面2043，在转动锁紧按板204时，该弧形导向面2043能够与安装座203或固定腿管201配合实现转动导向。
锁紧件206与锁紧按板204可以通过轴205同轴设置，当然也可以不同轴，如设置在锁紧按板204靠近活动腿管202一侧上，只要锁紧按板204的移动能够带动锁紧件206相对于活动腿管202移动即可。锁紧件206与锁紧按板204可以通过轴205同轴设置时，可以在锁紧按板204的抵脚2042内侧设置锁紧件限位块，以防止锁紧件206左右位移。
锁紧件206包括能够与活动腿管202紧密配合实现锁紧的锁紧端2061以及与锁紧按板204连接的连接端2062，锁紧端2061在锁紧按板204的联动下实现与活动腿管202相抵及分离从而实现锁紧和解锁。作为优选结构，锁紧件206 为U形件，锁紧件206开口端为连接端2062，连接端2062上设有锁紧件插销孔2063，锁紧件插销孔2063用于与插销205连接，远离开口端的一端为锁紧端2061，活动腿管202穿过锁紧件206，在锁紧状态下，锁紧端2061与活动腿管202相抵，在解锁状态下，锁紧端2062与活动腿管202分离。
锁紧按板204与锁紧件206同轴设置时，锁紧按板204与锁紧件206的具体联动方式如下：向外扳动锁紧按板204，轴205在锁紧按板204的作用下沿行程孔2033移位至行程孔2033靠近活动腿管端，轴205同时带动锁紧件206移动，锁紧件206的锁紧端2061的内侧壁与活动腿管202外侧壁分离，从而与活动腿管202形成间隙，使得活动腿管202能够上下活动，实现解锁；向内扳动锁紧按板204，在抵脚2042的作用下，使得轴205沿行程孔2033移位至行程孔2033远离活动腿管端，轴205同时带动锁紧件206移动，锁紧件206的锁紧端2061的内侧壁与活动腿管202外侧壁紧密相抵，从而消除与活动腿管202形成间隙，使得活动腿管202锁定，避免活动腿管202上下活动，实现锁定。
实施例2：
如图6-8所示，本实施例中的锁紧按板204靠近活动腿管202一侧还设有向活动腿管202处延伸的限位块2041，在锁紧状态下，限位块2041与活动腿管202相抵，与锁紧件206相互填充间隙，实现辅助锁紧效果。作为优选结构，限位块2041设置在抵脚2042之间。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
