DOOR CLOSING DEVICE
The present disclosure provides a door closer, including a first connecting plate and a second connecting plate, wherein the first connecting plate and the second connecting plate are respectively connected to an external door frame and a door body connecting portion, a hydraulic rod, connecting rod assemblies and return springs are mounted in the door body connecting portion, a connecting seat is fixed to the first connecting plate, and one end of the connecting rod assembly passes through the first connecting plate and the second connecting plate and then is fixed to the connecting seat; when a door is opened, an external door body drives the first connecting plate and the second connecting plate to overturn, and after the connecting rod assembly moves, the hydraulic rod and the return spring are driven to contract; and when the door is closed, the return spring drives the door body to close automatically. According to the door closer of the present disclosure, the connecting seat is connected to the door body connecting portion via the connecting rod assembly; when the door body is opened, a connecting rod is driven to move, at the same time, the connecting rod drives the hydraulic rod and the spring to contract via a base; a positioning boss for positioning is further disposed on a guide sliding block, so that the opened door body can be fixed; and when the door is closed, the hydraulic rod and the spring expand, which can drive the door body to close automatically.
