Automatic door closing device and cabinet comprising same
The invention relates to an automatic door closing device and a cabinet comprising the same. According to the automatic door closing device comprising a first contact switch, a first coil, a first elastic piece and a fixing piece, when a cabinet door needs to be kept in an open state, a first contact of the first contact switch is switched off, a second contact of the first contact switch is switched on, the first coil is in a power-on state and attracts a magnetic material of the fixing piece, and therefore the first elastic piece is kept in a stress state; therefore, the cabinet door is kept in an open state; and when the condition of automatically closing the cabinet door is met, the second contact is disconnected, and the first contact is closed, so that the first coil is turned into a power-off state, and the first elastic piece recovers a non-stress state and drives the cabinet door to be closed. By means of the arrangement, it can be guaranteed that the cabinet door can be normally opened for use, and the cabinet door can be automatically closed under proper conditions, so that potential safety hazards possibly caused by forgetting to close the cabinet door are avoided.
本申请涉及一种自动闭门装置和包含其的柜体。其中，通过包括第一触点开关、第一线圈、第一弹性件和固定件的自动闭门装置，在柜门需保持打开状态时，第一触点开关的第一触点断开，第二触点闭合，第一线圈处于通电状态并吸引固定件的磁性材料，以使第一弹性件保持受力状态，从而使柜门保持打开状态；而在满足自动关闭柜门的条件时，第二触点断开，第一触点闭合，以使第一线圈变为断电状态，使得第一弹性件恢复不受力状态并带动柜门关闭。如此设置，可以保证柜门能够正常打开使用，且在合适的条件下能够自动关闭，以避免因忘关柜门而可能导致的安全隐患。
