Description

Technical Field

[0001] This utility model relates to the field of door closer technology, specifically a door closer protective cover. Background Technology

[0002] A door closer is a device installed on a door, its main function being to automatically close the door after it has been opened, ensuring that the door returns to its initial position accurately and promptly. The door closer works by using a hydraulic or pneumatic system to control the closing speed and force, thus achieving a buffering effect and protecting the door frame and door body from damage.

[0003] Existing door closers have one end connected to the transmission mechanism and the other end rotatably connected to the door frame. However, most door closers expose their components directly, making them susceptible to rain or dust damage over time, significantly reducing their lifespan and consequently affecting the user experience of the door with the door closer installed. Therefore, a door closer protective cover is proposed. Utility Model Content
