The invention relates to the technical field of express storage equipment, and discloses an electromagnetic lock for an express cabinet, the electromagnetic lock comprises a sliding rod and a mounting plate which are respectively mounted on a cabinet door and a cabinet frame, a mounting cylinder is movably connected with the sliding rod and an adjusting plunger, and a closed pressure cavity is formed between the adjusting plunger and the mounting cylinder. According to the electromagnetic lock for the express cabinet, when the door is opened and closed, the air inflation bag and the air extraction bag are squeezed, when the switch cabinet door is abnormal, the pressure in the pressure cavity is changed through the air inflation bag or the air extraction bag, the position of the adjusting plunger is adjusted, and the elastic force of the spring is changed, so that the sliding rod and the wedge-shaped head can be smoothly popped out or retracted, and normal closing and opening of the cabinet door are guaranteed; and secondly, the door cannot be normally closed when only one point of the cabinet door is connected through the inclined plate, the door can be closed only when the limiting plate presses the air pumping bag, locking after the door is closed is guaranteed, virtual closing is avoided, and the locking reliability is improved.
本发明涉及快递存放设备技术领域，且公开了一种快递柜用电磁锁，包括分别安装在柜门和柜框上的滑杆和安装板，所述安装筒活动连接有滑杆和调整柱塞，所述调整柱塞与安装筒之间形成封闭的压力腔。该快递柜用电磁锁，开关门时会挤压充气囊和抽气囊，当开关柜门异常时，会通过充气囊或抽气囊改变压力腔内的压力，调整调整柱塞的位置，改变弹簧的弹力，使得滑杆和楔形头可顺利弹出或缩回，保证柜门的正常关闭和开启，保证快递的正常投放和取出，其次，通过倾斜的斜板保证柜门在只有一点连接时无法正常关门，只有当限位板压上抽气囊时才能实现关门，保证关上门后的锁定，避免虚关，提高锁定的可靠性。
