Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Combine fig. 1 and fig. 2 to show, a box body hasp structure, including the hasp body 101 that can insert to the lockhole, hasp body 101 one end fixedly connected with link plate body 102, link plate body 102 keeps away from the one end fixedly connected with of hasp body 101 and promotes structure 103, removes it can drive hasp body 101 and take place to remove on the horizontal direction to promote structure 103.

The utility model discloses, during the use, the user drives hasp body 101 through removing promotion structure 103 and takes place to remove on the horizontal direction to make hasp body 101 insert or shift out the lockhole of setting on the box body, thereby realize locking or opening between box body and the lid. The event the utility model discloses utilize to promote structure 103 and drive the hasp body 101 at the horizontal direction translation to realize that the hasp body inserts or shift out the lockhole, realize locking or open, need not to exert great power, convenient to use because of the fine deformation takes place for hasp itself at the opening in-process.

Preferably, the locking body 101 and the connecting plate body 102 are perpendicular to each other to form an "L" shape. Thus, after the locking body 101 is inserted into the locking hole, the connecting plate 102 can be tightly attached to the side surface of the box cover or the box body, so that the structure is compact.

As shown in fig. 2 and 3, the pushing structure 103 includes a pushing plate 104 and a driving plate 105 fixedly connected to each other, and one end of the driving plate 105 is fixedly connected to the connecting plate 102.

Preferably, the end of the push plate 104 remote from the driver plate 105 extends in a vertical direction. The utility model discloses the extension of following vertical direction here includes vertical extension and slope extension two kinds of condition. This allows the pusher plate 104 to form a pusher surface for receiving force in a vertical direction, which facilitates the application of force by the user.
