 附图说明
图1为本发明一种炉架铰链与炉架安装时的结构示意图。
图2为本发明的一种炉架铰链的立体装配结构示意图。
图3为本发明的一种炉架铰链的爆炸结构示意图。
 本发明的最佳实施方式
以下结合附图对本发明的结构做进一步说明。
参照图1至图3，一种炉架铰链包括有固定座1，固定座上固定设有套筒2，套筒2内转动设有的用于安装炉架3的铰轴4，炉架与铰轴的两端连接，铰轴与套筒之间设有控制炉架自动关闭悬停的阻尼装置5，阻尼装置5包括有套设于铰轴上的阻尼块51，与阻尼块连接的弹簧52，以及驱动弹簧伸缩的凸轮机构53，凸轮机构53包括有轴向滑动设于铰轴上的凸轮531，凸轮的一端与弹簧连接，凸轮的另一端设有V形槽5311，V形槽内的铰轴上固定设有推动凸轮轴向滑动的驱动轮532。本实施例中，阻尼块设于铰轴的中间，阻尼块的两端分别连接一个弹簧，两个弹簧的两边分别连接一个凸轮。凸轮上设有沿轴向的限位肋5312，套筒内设于与限位肋配合的限位槽，从而使凸轮沿轴向滑动。当转动炉架时，炉架带动铰轴转动，铰轴上的驱动轮驱动弹簧伸缩，从而产生一个对炉架的扭力，扭力的大小随着驱动轮与V形槽的相对位置变化而变化，当扭力与炉架的重力的合力大于阻尼块的摩擦力时，炉架自动关闭；当扭力与炉架的重力的合力等于阻尼块的摩擦力时，炉架悬停。从而需要清洁炉灶时，将炉架向上转动至悬停状态对炉灶进行清洁，清洁完毕，将炉架转动到一定角度使炉架自动关闭，从而使用方便。
本实施例中，阻尼块由多个C形的弹片并排叠加在一起组成。C形的弹片为锰钢片，冲压形成，后处理加硬。可以通过调节C形的弹片的个数来调节阻尼力的大小。同时便于安装。本发明的铰链所有部件都为金属材料，能够耐高温，满足厨具的高温要求。
本实施例中，V形槽与铰轴配合的两侧面为对称的螺旋面，V形槽底部为圆弧面。从而可以根据炉架的重力来调节螺旋面的螺旋形状，同时能够使驱动轮与螺旋面能够稳定顺畅的连接，使炉架能够稳定转动。另外此种阻尼装置因为有弹簧的弹力作用，从而活动时，活动部件之间不会晃动，从而能够实现静音闭合和悬停。
本实施例中，铰轴4上设有炉架安装孔6，炉架3上设有与炉架安装孔轴轴向配合卡接的炉架安装轴31，炉架安装孔6的侧面开设有用于炉架安装轴进入到炉架安装孔内的第一炉架安装入口61，套筒2上设有供炉架安装轴进入到炉架安装孔内的第二炉架安装入口21。安装时，炉架先通过第二路径安装入口再通过第一炉架安装入口进入到炉架安装孔内。本实施例中，炉架通过分别设于铰轴两端的炉架安装座7与铰轴连接，铰轴安装座分别与铰轴的两端连接，炉架安装孔设于铰轴安装座上。炉架安装座的一端与铰轴轴向卡接，炉架安装座的另一端与炉架卡接。炉架安装座7上设有与铰轴配合的扁卡槽71。从而方便安装。
本实施例中，炉架安装孔竖直朝上时，驱动轮位于V形槽的最底部。此时，弹簧伸缩到最大长度，弹簧对炉架产生的扭力最小，当炉架带动铰轴向两边转动时，弹簧逐渐压缩到最大，弹簧对炉架产生的扭力逐渐变大，当炉架转动到水平状态时，此时驱动轮位于V形槽的最上端，此时的扭力最大。本实施例中，第二炉架安装入口位于套筒的顶部。从而当炉架安装孔竖直朝上时与套筒的顶部的第二炉架安装入口对齐，此时因为弹簧对炉架产生的扭力最小，此时能够轻易的将炉架取下，从而便于炉架的拆卸。
本实施例中，当炉架转动到水平状态时，此时驱动轮位于V形槽的最上端，此时的弹簧对炉架的扭力最大。当门板向上转动过程中，扭力逐渐减小，门板的分力逐渐减小，门板与竖直方向的夹角小于30度的范围内，弹簧对炉架的扭力与炉架的重力的合力大于阻尼块的摩擦力，炉架自动关闭；当门板继续向上转动过程中，扭力逐渐减小，门板的分力逐渐减小，门板与竖直方向的夹角在30到90度之间时，弹簧对炉架的扭力与炉架的重力的合力等于阻尼块的摩擦力，此时门板处于悬停状态，而在90度时，弹簧对炉架的扭力达到最小。
本实施例中，门板最大角度打开时，门板与竖直方向的夹角为110度。套筒2上设有用于限制炉架转动到最大角度的限位槽22，炉架3上设有与限位槽配合的限位块32。当炉架转动到最大角度时，炉架上的限位块被限位槽挡住，从而限定炉架的最大转动角度。具体实施时，还可以根据需要设置其它的炉架的最大转动角度。在炉架从90度到110度的转动过程中，弹簧对炉架的扭力增大，炉架的重力的分力增大，在90度到110度之间，弹簧对炉架的扭力与炉架的重力的合力等于阻尼块的摩擦力，此时门板处于悬停状态。从而炉架在30度以内自动关闭，在30到110度之间悬停，从而需要清洁炉灶时，将炉架向上转动至悬停状态对炉灶进行清洁，清洁完毕，将炉架转动到30度以内使炉架自动关闭，从而使用方便。
虽然结合附图对本发明的具体实施方式进行了详细地描述，但不应理解为对本发明的保护范围的限定。在权利要求书所描述的范围内，本领域技术人员不经创造性劳动即可做出的各种修改和变形仍属于本发明的保护范围。
