Description

Technical Field

[0001] The utility model relates to the technical field of industrial safety door locks, and particularly relates to a safety door lock switch contact combination structure. Background Technique

[0002] As the name implies, a door lock is a device used to lock a door to prevent others from opening it. There are many classifications of door locks, and the requirements for door locks vary in different occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively inexpensive.

[0003] Relevant technical personnel engaged in the design of safety door locks found during actual work that there are various types of switch contacts, and the design of the structure requires opening multiple sets of different types of molds to adapt to the changes in the types of contacts, which is costly and cumbersome to assemble. Moreover, the moving shaft is an integral whole. To achieve multiple types of switch types, multiple molds must be opened to realize different switch types. At the same time, since its moving shaft is an integral whole, it is impossible to achieve stepped wiring, resulting in relatively difficult wiring and a risk of wire crossing. For this reason, we propose a safety door lock switch contact combination structure. Content of the Utility Model
