技术领域technical field
本实用新型涉及一种铰链机构,尤其涉及一种用于安装电子设备、仪表等具有可以旋转打开面板的内置式的铰链机构。The utility model relates to a hinge mechanism, in particular to a built-in hinge mechanism with a panel that can be rotated and opened for installing electronic equipment, instruments and the like.
背景技术Background technique
为了便于设备的操作及维护,目前的各类电子设备的机箱均设计有可以开启的门结构类的面板;该类可旋转打开的面板的旋转机构大致有两种方式:一是采用转轴在轴孔旋转来实现,其结构简单,易于加工。但是这种旋转结构,很难实现面板打开角度的限制;同时对面板厚度有一定要求,对于较薄面板无法安装。二是设计专用的铰链机构来实现,此方式可采用模具化加工,加工成本和精度均可得到很好控制。In order to facilitate the operation and maintenance of the equipment, the cabinets of various electronic equipment are designed with panels that can be opened. There are roughly two ways for the rotation mechanism of this type of panel that can be rotated and opened: one is to use the rotating shaft on the shaft. It is realized by hole rotation, and its structure is simple and easy to process. However, with this rotating structure, it is difficult to limit the opening angle of the panel; at the same time, there is a certain requirement for the thickness of the panel, and it cannot be installed for a thinner panel. The second is to design a special hinge mechanism to realize it. This method can be processed by mold, and the processing cost and precision can be well controlled.
但是,目前现有的电子设备可旋转面板铰链机构,大多为外置结构,不但影响设备的外观,且不可以限定打开角度,当面板旋转转角过大时,会导致面板和设备机壳产生撞击,致外观破损;另一方面,当机架上需要上下安装多层设备时,上层设备面板的过度打开会遮挡下层的面板,影响其他设备的使用和运行。因此,有必要在电子设备旋转面板上设置可以限定其打开角度的内置式铰链机构。However, most of the existing hinge mechanisms for rotatable panels of electronic equipment are external structures, which not only affect the appearance of the equipment, but also cannot limit the opening angle. When the panel rotation angle is too large, it will cause collision between the panel and the equipment casing , resulting in damage to the appearance; on the other hand, when multiple layers of equipment need to be installed up and down on the rack, the excessive opening of the upper equipment panel will block the lower panel, affecting the use and operation of other equipment. Therefore, it is necessary to provide a built-in hinge mechanism that can limit the opening angle of the rotating panel of the electronic device.
