Description
technical field [0001] The present application relates to a latch mechanism applied in the industrial field, in particular to a latch mechanism capable of automatic opening and closing. Background technique [0002] Door mechanisms used in industry usually need to be opened and closed repeatedly. In the prior art, the opening and closing of the door are performed manually, which will bring complicated operation and consume a lot of physical strength and manpower. On the other hand, manual operation often causes incorrect opening and closing operations due to errors. Reliable, which in turn leads to an increased failure rate. Especially in an environment that is not suitable for manual opening, the automatic unlocking and locking functions of the door are often difficult to realize. Contents of the invention [0003] Based on the above reasons, the present invention provides a locking mechanism capable of automatic opening and closing. Through the present invention, only...
