发明的有益效果
对附图的简要说明
附图说明
[0023] 图 1为本实用新型一种结构示意图;
[0024] 图 2为图 1中 A部位放大图;
[0025] 图 3为图 2左视图;
[0026] 图 4为图 2俯视图;
[0027] 图 5为本实用新型局部结构示意图;
[0028] 图 6为本实用新型另一种结构示意图。 [0029] 图中: 1横杆, 2连杆, 10横杆孔, 11卡件, 12拆卸口, 21卡勾件, 210卡槽, 2 11连接面, 212固定面, 3层板。
发明实施例
本发明的实施方式
[0030] 下面结合附图对本实用新型进行进一步说明:
[0031] 如图 1、 6所示, 无限延伸架, 包括横杆 1和连杆 2; 所述横杆 1设有一个或多个 横杆孔 10, 所述连杆 2两端设有卡勾件 21, 所述卡勾件 21设有卡槽 210; 所述横 杆 1两端分别设有一个横杆孔 10; 所述连杆 2两端的卡勾件 21同向设置。
[0032] 位于横杆 1同一侧边的两个连杆 2相互平行, 且两个连杆 2还连接有层板 3。 所述 横杆 1上的两个横杆孔 10对称设置, 两个卡件 11均设置在所述横杆孔 10靠近横杆 1端面的一端; 或, 两个卡件 11均设置在所述横杆孔 10靠近横杆 1端面的一端。
[0033] 需要说明是, 前段中的横杆 1端面是指与横杆孔 10相邻、 最接近的端面, 比如 图 2中, 该横杆孔 10与横杆 1左端最接近, 因此, 端面指代横杆 1左端面; 上述横 杆孔 10靠近横杆 1的端面指代距离其最近的横杆 1端面。
[0034] 如图 1所示, 使得两个连接杆 2被碰撞时, 受到同一方向力, 不会因为两个连接 杆 2向同一方向移动而发生脱钩的现象。 当如图 1中结构时, 至右当两个连接杆 2 做相互靠近的运动时, 卡勾件 21才能与卡勾 11脱离。
[0035] 横杆孔 10对称设置, 包括内部结构也相互对称, 使得通过层板 3连接的连杆 2只 能同向移动, 而无论连杆 2在横杆 1上如何移动, 都不会发生脱钩的现象, 两个 连杆 2至右运动方向相仿时, 才能相对于横杆 1的横杆孔 10脱勾。
[0036] 所述横杆 1两端连接有支架。 横杆 1与支架为预装, 比如两个纵向的支架和两个 横向的横杆 1连接后, 构成一个平面, 更加便于运输。 通过, 两侧采用预装固定 模式, 而不是全部采用组装结构, 增加了架体整体的结构强度。
[0037] 如图 2-4所示, 所述横杆孔 10开设在所述横杆 1的同一面, 所述横杆孔 10中一端 设有 2个卡件 11, 另一端为拆卸口 12, 2个所述卡件 11设置在相对的两侧; 拆卸 口 12为横杆孔 12未设置卡件 11的部分。 所述拆卸口 12的长度大于或等于所述卡 勾件 21的宽度; 需要拆卸时, 将连杆 2从卡件 11的位置推动至拆卸口 12中, 当卡 勾件 21移动至拆卸口 12后, 卡勾件 21与卡件 11托卡, 两者分离。 [0038] 所述连杆 2两端连接于两个横杆 1 ; 所述卡勾件 21连接于所述横杆孔 10设置有卡 件 11一端时, 卡勾件 21卡接所述横杆孔 10内的卡件 11 ;
[0039] 卡槽 210设置在固定面 212内侧, 内侧为其最接近横杆 1的一侧面。 卡槽 210设置 在固定面 212内侧面, 其与卡件 11连接后, 卡槽 210能与位于其内侧的卡件 11卡 接。
[0040] 如图 5所示, 所述连杆 2上设有层板 3。 层板 3可通过预设的卡接装置 2连接, 只 要能将连杆 2固定连接在层板 3上即可。
[0041] 如图 1-4所示, 所述横杆 1垂直连接所述连杆 2; 所述卡勾件 21连接于所述横杆 孔 10设置有卡件 11一端时, 所述卡槽 210卡接所述卡件 11下端。 所述卡勾件 21为 U型, 所述卡勾件 21的连接面 211连接于连杆 2的端面, 所述卡槽 210设置在所述 卡勾件 21的固定面 212下端。 当卡勾件 21与卡件 11卡接时, 将连杆 2提起时, 横 杆 2也随之移动, 两者不会脱钩。
[0042] 所述连接面 211平行于所述固定面 212。 连接面 211可以为连杆 2的一部分, 不限 定其具体的结构, 为了便于表述, 将卡勾件 21与连杆 2连接部位统称为连接面 21 1, 该连接面可以为连杆 2端面与连接部的统称。 卡槽 210也并非将其限定位凹槽 型, 为一种能与卡件 11起到限位作用的构件, 凹槽为其中一种方式。
[0043] 本实用新型的一种工作方式为:
[0044] 如图 1、 6, 在一个横杆 1两侧连接连杆 2, 连杆 2与横杆 1的具体连接方式如图 2- 4所示, 卡勾件 21与卡件 11卡接。 位于横杆 1同一侧的两根连杆 2还连接有层板 3 , 层板 3将两根连杆 2间距固定, 使两者不能做靠近或远离运动, 从而避免了卡 勾件 21与卡件 11的脱钩。
[0045] 按上述组装延伸架, 安装时可以将卡勾件 21从卡件 11的位置按下, 然后卡勾件 21与卡件 11卡接, 也可先将卡勾件 21从拆卸口 12按入, 然后将卡勾件 21向卡件 1 1位置平移, 平移后卡勾件 21与卡件 11卡接。
[0046] 同一个横杆 1两侧均可连接有连杆 2, 然后两相邻的横杆 1之间的连杆 2通过层板 3连接, 层板 3将连杆 2间距固定, 实现无线延伸。
[0047] 如图 2、 3所示, 连杆 2的之间的间距被层板 3固定, 由于卡勾件 21与卡件 11卡接 , 连接面 211与横杆 1外侧面相接触, 防止了连杆 2相对于横杆 1转动, 也起到了 限位作用, 因此不能直接将卡勾件 21从卡件 11卡接位置向上拔出。 需要拆卸时 , 先将层板 3拆卸, 将连杆 2向拆卸口 12的位置移动 (两个连杆 2的移动方向为相 反或相对) , 当连杆 2完全位于拆卸口 12后, 将卡勾件 21从拆卸口 12拔出。
[0048] 本实用新型中“上下左右”以相应的附图中方位为参考, 均是为了便于表述, 不 具备其他特殊含义。
[0049] 此外, 本实用新型并不局限于上述实施方式, 只要其以基本相同的手段达到本 实用新型的技术效果, 都应属于本实用新型的保护范围。
