Automatic door closing device and display cabinet
The invention discloses an automatic door closing device. The automatic door closing device comprises a hinge, a rotating assembly, a first adjusting piece and a second adjusting piece, wherein the hinge is arranged at the lower end of a box, the rotating assembly is arranged on a door, the first adjusting piece is fixedly arranged on the hinge and provided with a first boss, the end faces of twosides of the first boss are first inclined surfaces, the second adjusting piece is fixed to the bottom end of the door, rotatably connected with the rotating assembly and provided with a second boss,and the end faces of two sides of the second boss are second inclined surfaces. The first boss and the second boss are correspondingly arranged, and the structures of the first boss and the second boss are matched, so that the second adjusting piece can automatically and stably slide downwards along the inclined surfaces of the first boss until the door is closed. When the door is completely closed, the first adjusting piece and the second adjusting piece can be clamped together. The technical problem that an automatic door closing device in the prior art cannot achieve automatic and stable closing of the door after small-angle and large-angle door opening at the same time is solved.
本发明公开了一种自动关门装置，包括铰链，铰链设置于箱体下端；转动组件，其设置于门体上；第一调节件，其固定设置于铰链上；且第一调节件上设置有第一凸台，第一凸台的两侧端面均为第一斜面；第二调节件，其固定于门体底端且与转动组件转动连接；且第二调节件上设置有第二凸台，第二凸台的两侧端面均为第二斜面；其中，第一凸台与第二凸台相对应设置，且第一凸台与第二凸台的结构相配合；使得第二调节件能够沿着第一凸台的斜面自动且稳定的向下滑动至门体关闭；当门体完全关闭时，使得第一调节件与第二调节件能够卡合在一起。解决了现有技术中自动关门装置无法使得门体同时实现小角度和大角度开门后自动且稳定关闭的技术问题。
