A mechanical locking type automatic door opening and closing device

Abstract

The invention discloses a mechanical locking type automatic door opening and closing device, which comprises a limit frame, and is characterized in that a sliding door is slidably connected to the inside of the limit frame. In the present invention, by installing the manual unlocking mechanism, the limit block is plugged into the slot at the front end of the frame body. The ball pops out until it engages with the limit slots set on the top and bottom faces of the limit block. This design can realize the automatic locking function when the main door moves to the left, so as to achieve the purpose of automation. Lever self-locking mechanism, so in the present invention, when the main door slides to the left, the slider at the bottom will use the principle of leverage to drive the plug on the right to insert into the limit groove A through contact with the plug Position, in order to achieve the purpose of automatically locking the main door, this design can improve the overall security of the door sliding door.

Description

technical field [0001] The invention relates to the technical field of automatic locking doors, in particular to a mechanical locking type automatic door opening and closing device. Background technique [0002] Automation refers to the process of automatic detection, information processing, analysis and judgment, manipulation and control of machines, equipment, systems or processes (production, management processes) without the direct participation of people or fewer people, according to people's requirements, to achieve the expected goals. Process, automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, service and family; [0003] As a tool that is used more frequently in daily life, the door body needs to use automation to realize the self-locking operation of the door body during use, so as to prevent the user from forgetting. [0004] For example, application number: CN 201811573114.X The pr...

Problems solved by technology

[0005] Based on the retrieval of the above-mentioned patents, and in combination with the equipment in the prior art, it is found that although the above-mentioned equipment can perform automatic door opening and closing operations during application, in the actual application process, most of the existing door locking devices are single One-point locking operation, so the security is low. Once a single point is damaged, the entire door body can be opened. Moreover, the self-locking operation of the door body cannot be realized, so there will be safety hazards caused by forgetting to lock the door
