PURPOSE: An automatic locking device for a side-by-side door is provided to improve convenience by automatically locking or unlocking a door when a user closes or opens the door. CONSTITUTION: An automatic locking device for a side-by-side door comprises a housing(100), an expansion link member(110), a bolt member(150), an elastic expansion member, pressing members(170), and a streamlined protection member. The housing has a through hole. The expansion link member is buried in the housing and is composed of multiple unit links(111). The bolt member is fixed to the bottom end of the expansion link member and is protruded through the through hole of the housing when the bolt member is stretched. The elastic expansion member maintains the contracted state of the expansion link member. The pressing members are connected to both ends of the expansion link member. The spiral protection member pushes the pressing members to the inside the housing. |
