[0006] 本发明的电磁释放闭门器， 滑轨上设有相互平行的滑槽和滑行腔， 滑槽与滑行 腔之间设有与滑槽平行的通槽， 其中电磁限位机构可固定于滑行腔内的任意位 置； 电磁铁通电状态下， 电磁吸板与电磁铁在磁力的作用下处于固定状态， 限 位斜舌位于滑槽中， 用于限制滑块在滑槽中的滑行， 此状态下， 滑块可在限位 斜舌与滑槽一端的端部之间自由滑行， 即门扇可在限位斜舌所限定的位置与最 大打幵位置之间自由活动， 改变了现有技术门扇只能固定于于某一特定状态的 缺陷， 调节范围较大， 使用更加灵活， 可以适应更多的使用需求。
[0007] 同吋， 由于弹簧一的强度足以保证门扇正常幵启状态下， 不足以压缩弹簧一使 滑块通过限位斜舌， 在门扇受到较大的冲击力吋， 滑块会驱使限位斜舌压缩弹 簧一直至滑块通过限位斜舌， 可以防止门扇收到较大冲击力吋损坏闭门器装置
[0008] 在电磁铁断电状态下， 电磁吸板与电磁铁脱离， 由于弹簧二的强度较小， 正常 幵关门吋均可以由滑块驱使限位斜舌压缩弹簧二， 直至滑块通过限位斜舌， 即 门扇可自由幵闭。

实施该发明的最佳实施例
本发明的最佳实施方式
[0019] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 ， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0020] 如图 1-3、 图 9所示， 本实施例的一种电磁释放闭门器， 包括闭门器主体 5、 滑 轨 1和摇臂 2。 其中滑轨 1的上表面设有滑槽 11， 滑轨 1的内部设有与滑槽 11平行 的滑行腔 12， 其中滑槽 11与滑行腔 12之间设有与滑槽 11平行的通槽 （图中未示 出） ， 且通槽的宽度小于滑槽 11和滑行腔 12的宽度。
[0021] 本实施例的摇臂 2的一端连接有用于在滑槽 11中滑行的滑块 3， 摇臂 2与滑块 3之 间旋转活动连接。 作为本实施例最大的改进， 在滑行腔 12内设有可在滑行腔 12 内滑行的限位装置 4， 其中限位装置 4包括电磁限位机构 41、 位于滑行腔端部的 控制电路组件 42以及用于连接电磁限位机构 41和控制电路组件 42的弹簧线 43， 其中弹簧线 43的伸缩性能为电磁限位机构 41在滑行腔 12内的移动提供了可能。
[0022] 如图 3所示， 本实施例的电磁限位机构 41包括电磁铁 411和电磁吸板 415， 其中 电磁铁 411的中部设有贯穿电磁铁的导向孔 412， 电磁铁 411的两端设有紧固螺纹 孔 413， 紧固螺纹孔 413内连接有紧固螺栓 414。 在拧入紧固螺栓 414的过程中， 电磁铁 411的上表面与滑行腔 12的顶面逐渐贴合直至压紧， 从而将电磁限位机构 41固定于滑行腔 12内的任意位置。
[0023] 在本实施例中， 上述导向孔 412内设有限位斜舌 416， 限位斜舌 416通过螺钉 417 与电磁吸板 415连接， 其中螺钉 417与限位斜舌 416固定连接， 螺钉 417与电磁吸 板 415之间沿螺钉的轴向活动连接。 电磁铁 411通电状态下， 电磁吸板 415在电磁 力的作用下与电磁铁固定连接， 限位斜舌 416由通槽进入滑槽 11中， 从而限制滑 块 3通过限位斜舌 416的位置。
[0024] 作为本实施例的一大改进， 限位斜舌 416与电磁吸板 415之间设有弹簧一 421， 电磁吸板 415与滑行腔 12的腔底之间设有弹簧二 418。 作为优选， 限位斜舌 416靠 近电磁吸板 415的一侧设有环形容纳槽 420， 其中弹簧一 421的一端位于环形容纳 槽 420中， 另一端与电磁吸板 415抵压接触； 电磁吸板 415远离限位斜舌 416的一 侧设有沉头孔 419， 其中弹簧二 418的一端位于沉头孔中， 另一端与滑行腔 12的 腔底抵压接触。
[0025] 需要说明的是， 其中弹簧一 421的强度大于弹簧二 418的强度。 其中弹簧一 421 的强度足以保证门扇正常幵启状态下， 不足以压缩弹簧一 421， 使滑块 3无法通 过限位斜舌 416。 此状态下， 滑块 3可在限位斜舌 416与滑槽 11一端的端部之间自 由滑行， 即门扇可在限位斜舌 416所限定的位置与最大打幵位置之间自由活动， 改变了现有技术门扇只能固定于于某一特定状态的缺陷， 调节范围较大， 使用 更加灵活， 可以适应更多的使用需求。 当门扇受到较大的冲击力吋， 冲击力大 到足以使滑块 3驱使限位斜舌 416压缩弹簧一 421直至滑块 3通过限位斜舌 416， 可 以有效防止门扇收到较大冲击力吋损坏闭门器装置。
[0026] 本实施例的电磁释放闭门器在电磁铁 411断电状态下， 电磁吸板 415与电磁铁 41 1脱离， 由于弹簧二 418的强度较小， 正常幵关门吋均可以由滑块 3驱使限位斜舌 416压缩弹簧二 418， 直至滑块 3通过限位斜舌 416， 即门扇可自由幵闭。
[0027] 其中在图 4所示状态下， 限位斜舌 416位于 B1位置， 则滑块 3可以在极限位置 A 与 B1位置之间自由活动， 即门扇可在最大打幵位置与限位斜舌限定的位置 B1之 间幵闭。 同理， 在图 5状态下， 限位斜舌 416固定于 B2位置吋， 滑块 3可以在极限 位置 A与 B2位置之间自由活动， 即门扇可在最大打幵位置与限位斜舌限定的位置 B2之间幵闭。 [0028] 进一步的， 如图 5、 图 6所示， 本实施例电磁释放闭门器， 其中滑轨 1的两端均 设有相互垂直的横向安装孔 13和竖向安装孔 14。 使得本实施例的电磁释放闭门 器既可以安装于门扇的顶面， 又可以安装于门扇的侧面， 而且在不同方向的门 扇上安装吋不用翻转方向， 适用于在更多类型的门上安装本实施例的电磁释放 闭门器。
[0029] 图 9所示为本实施例的电磁释放闭门器安装状态的示意图， 其中滑轨安装于门 扇的顶部， 闭门器主体 5安装于门框上。 在该种类型的安装过程中， 为了尽可能 的缩小门框和门扇顶端之间的安装间隙， 以及减小门框的尺寸， 本实施例的电 磁释放闭门器对于摇臂 2两端的连接结构做了特别的设计。
[0030] 其中摇臂 2与滑块 3连接的一端如图 6-8所示， 其中摇臂 2与滑块连接的一端设有 贯穿摇臂 2的连接孔一 21， 该连接孔一 21的侧壁上设有至少两个与连接孔一 21垂 直且贯穿连接孔一 21侧壁的螺纹孔 23。 摇臂 2与滑块 3之间通过摇臂轴 33连接， 其中摇臂轴 33如图 7所示， 包括柱状连接部 331和环台 332， 柱状连接部 331上设 有环槽 333。 其中滑块 3包括滑块本体 31与盖板 32， 盖板 32与滑块本体 31之间通 过螺栓 34连接， 且摇臂轴 33的环台 332位于盖板 32与滑块本体 31之间， 相对滑块 3固定连接。 如图 8所示， 摇臂轴 33设有环槽 333的一端伸入摇臂 2的连接孔一 21 中， 此状态下， 环槽 333在连接孔一 21中的位置与螺纹孔 23的高度相同。 接着在 螺纹孔 23中拧入柱螺栓 35， 连接状态下， 摇臂轴 33远离滑块 3的一端不高于摇臂 2的上表面， 柱螺栓 35的一端位于环槽 333中， 另一端不高于摇臂 2的侧壁表面。
[0031] 进一步的， 如图 6、 图 10所示， 摇臂 2远离滑块 3的一端设有贯穿摇臂 2的连接孔 二 22， 通过六角方榫 221和螺栓 223将摇臂 2与闭门器主体 5进行固定连接， 该六 角方榫 221的一端伸入连接孔二 22中并与摇臂 2固定连接， 优选为边缘与摇臂 2焊 接。 其中六角方榫 221伸入连接孔二 22中的长度小于连接孔二 22的轴向长度， 所 述连接孔二 22远离六角方榫的一侧内设有沉头垫片 222。 连接状态下， 沉头垫片 222完全位于连接孔二 22中， 不会突出于摇臂 2的表面。
[0032] 上述摇臂 2两端的连接结构中， 摇臂轴、 柱螺栓和沉头垫片均未突出于摇臂的 表面， 安装完成后， 闭门器产品的高度较小， 有效降低了门框与门扇之间的间 [0033] 总之， 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本 发明的精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发 明的保护范围之内 本发明的实施方式
