实施该发明的最佳实施例
本发明的最佳实施方式
[0029] 下面结合附图与实施例对本发明的技术方案进行说明。
[0030] 实施例一
[0031] 如图 1至图 6所示， 本发明所述的本发明所述的具有缓冲功能的门铰链， 包括外 壳 1、 铰链杯 10以及连接件 A5和连接件 B8， 所述外壳 1内可轴向移动地设有阻尼 器 3， 所述阻尼器 3前端的活塞杆端部与外壳 1固定连接， 上述为本发明的主要部 件， 结构本发明的基本结构。
[0032] 所述连动件 A5的右端通过第一转轴 4转动地设在外壳 1内， 连动件 A5的左端通 过第三转轴与铰链杯 10转动连接； 所述连接件 B8的右端通过第二转轴 7转动地设 在外壳 1内， 连接件 B8的左端通过第四转轴与铰链杯 10转动连接。
[0033] 所述第二转轴 7上套设有扭力弹簧 6， 扭力弹簧 6的一端固定或抵靠在第四转轴 上， 扭力弹簧 6的另一端抵靠在外壳 1上； 所述连动件 A5的右端端部与阻尼器 3后 端对应设置。
[0034] 特别说明一下， 为提高产品的集成度， 简化装配手续， 所述第三转轴和第四转 轴可以一体成型为 "U"型转轴 9。
[0035] 使用吋， 夕卜壳 1和铰链杯 10分别固定于门和门框上， 当幵门吋， 连动件 A5的右 端端部驱动阻尼器 3向右移动， 达到较好的缓冲效果； 当关门吋， 扭力弹簧 6压 缩， 同吋阻尼器 3随连动件 A5向左移动， 达到较好的缓冲效果。 本发明连动件 A5 与阻尼器 3的移动方向在同一直线上， 行程大， 相对于现有技术而言， 缓冲效果 更佳。
[0036] 所述外壳 1内可轴向移动地设有阻尼器 3， 具体而言， 所述外壳 1前后两侧内壁 上分别设有定位块 11， 两个所述定位块 11与外壳 1的顶壁之间形成两个滑槽 12， 所述阻尼器 3两侧可轴向滑动地设于对应的两个滑槽 12内。 为提高可操作性和灵 活性， 所述阻尼器 3两侧分别设有定位滑块 31， 所述阻尼器 3通过两侧的定位滑 块 31与两个滑槽 12对应滑动配合。 这样设置， 结构简单， 极大降低了制作成本 ， 同吋， 也便于阻尼器 3的安装和拆卸， 维护简单方便， 维护成本较低。
[0037] 值得一提的是， 所述定位块 11为所述外壳 1前后两侧分别冲裁向内折弯的折片 或向内冲压形成凸起。 这种结构， 极大地简化了产品结构， 提高了产品的运行 可靠性， 同吋， 有效降低了成本。
[0038] 所述阻尼器 3前端的活塞杆端部与外壳 1固定连接， 具体而言， 本实施例采用两 种不同的实施方式。
[0039] 第一种实施方式为： 所述外壳 1内固定设有定位轴 2， 所述阻尼器 3的活塞杆的 端部设有挂钩 32， 所述挂钩 32挂设在定位轴 2上定位。
[0040] 第二种实施方式为： 所述外壳 1的顶部设有向下延伸的卡片 13， 所述阻尼器 3的 活塞杆的端部设卡槽 34， 所述卡槽 34卡设在卡片 13上定位。
[0041] 上述两种实施方式， 均是将所述阻尼器 3的活塞杆的端部可拆卸连接于壳体 1上 ， 便于阻尼器 3的安装和拆卸， 维护简单方便， 维护成本较低。
[0042] 所述阻尼器 3的后端部设有挡块 33， 所述连动件 A5的右端端部设有驱动部件 14 ， 所述驱动部件 14与挡块 33对应设置。 关于驱动部件 14与挡块 33的对应关系， 本实施例可以三种结构： 1.所述驱动部件 14为推动块， 与挡块 33抵触设置以驱 动阻尼器 3移动； 2.所述驱动部件 14为翘钩， 可以有效钩挡块 33以驱动阻尼器 3 移动； 3.所述驱动部件 14与挡块 33铰接连接以驱动阻尼器 3移动。
[0043]
[0044] 实施例二
[0045] 本实施例其它结构均与实施例一相同， 不做重复描述， 不同之处仅在于， 所述 驱动部件 14设于连接件 B8的右端端部， 由连接件 B8的转动并通过驱动部件 14驱 动阻尼器 3轴向移动。
[0046] 具体而言， 所述阻尼器 3的后端部设有斜面 35， 所述连接件 B8的右端端部设有 驱动部件 14 (推动块） ， 所述驱动部件 14与斜面 35对应设置。
[0047] 具体而言， 本实施例中的驱动部件 14可以抵触与斜面 35配合， 也可以驱动部件 14与阻尼器 3的后端部铰接连接。
[0048] 本实施例与实施例一在技术效果上也存在一定差异， 连接件 B8的第二转轴 7上 套设有扭力弹簧 6， 同吋连接件 B8的右端端部设有驱动部件 14与阻尼器 3对应， 在幵关门吋， 扭力弹簧 6与阻尼器 3配合更为直接， 缓冲效果更佳。
[0049] 以上所述仅是本发明的较佳实施方式， 故凡依本发明专利申请范围所述的构造 、 特征及原理所做的等效变化或修饰， 均包括于本发明专利申请范围内。
