Safe lock device of refrigeratory

Abstract

The invention relates to a safe lock device of a refrigeratory, which is mainly used for solving the problems that an existing openable door lock in the refrigeratory is complex in structure, is high in cost, and is poor in burglar prevention. The safe lock device is characterized in that a rotation shaft (5) is installed in a rotation shaft base (8) penetrating through a door body (7); one end of a buckling ring (6) is hinged with a buckle hand (4), and the other end of the buckling ring (6) sleeves a bending body (9) of the rotation shaft (5); after the rotation shaft (5) rotates for a certain angle, the buckling ring (6) can slide off from the bending body (9). For the safe lock device of the refrigeratory, the buckling ring can be separated away from the bending body on the rotation shaft after a handle is rotated by 180 degrees, and then a door of the refrigeratory is opened; the safe lock device has the characteristics of simple and exquisite structure, low cost, and good anti-theft performance.

Description

technical field [0001] The invention relates to a door lock for a cold storage door, in particular to a safety lock device for a cold storage. Background technique [0002] Cold storage is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions, also known as cold storage, freezing storage or freezing storage, which can extend the storage period of products to adjust market supply. At present, the cold storage door usually adopts a sliding door structure, that is, the left and right door leaves are opened or closed oppositely along the slideway, and the outside of the cold storage door is locked with a bolt and a padlock to achieve the purpose of anti-theft. Because the door is locked on the outside of the cold storage door, the cold storage door cannot be opened inside the cold storage. Once a negligent person is locked in the cold storage, it will pose a threat to the lives of the trapped people. In order to prevent people from ...
