A surface-mounted door closer is a door-closing device installed on the surface of a door. It offers the following advantages:
Easy Installation: Since the closer is mounted directly on the door surface, there is no need for complex slotting, drilling, or modifications to the door or frame. It also does not require specialized tools or skills. Regular users can follow the instruction manual to complete the installation, effectively saving time and cost.
Convenient Maintenance: Because the closer is exposed on the door surface, its operating condition is easy to inspect during routine maintenance. In the event of a malfunction, the problem can be quickly identified. Additionally, repairs or component replacements can be carried out without removing the door or damaging surrounding finishes, reducing maintenance costs and less impact on door usage.
Wide Applicability: Surface-mounted door closers are suitable for a variety of door types, including wooden doors, steel doors, and aluminum alloy doors. Whether for new construction or for retrofitting doors in existing buildings, surface-mounted closers can be easily installed without being limited by the door’s material or structure.
Durable and Reliable: These closers are typically made from high-strength materials and are designed with a solid structure to withstand heavy door loads and frequent operation. Their surfaces are often treated for corrosion and rust resistance, making them suitable for different environments and less prone to damage.
Versatile Functions: In addition to basic door closing, surface-mounted closers often allow for adjustment of closing speed, latching force, and other parameters to meet diverse needs. Some advanced models are equipped with cushioning features to reduce impact when closing, which helps to minimize noise and prevent damage to the door and frame.
Concealed Door Closer (Hidden Type)
A concealed door closer is a type of closing device installed inside the door or door frame, making it difficult to detect from the outside.
Its main advantages include the following:
Aesthetic Appeal: Installed within the door or frame, the concealed door closer does not affect the overall appearance of the door. It provides a cleaner, more streamlined look that blends seamlessly with various interior design styles. It is especially suitable for locations with high aesthetic requirements, such as upscale office buildings, hotels, and villas.
Enhanced Security: Since the concealed closer is installed internally, it is less prone to tampering or intentional damage. Compared to surface-mounted closers, it has a lower risk of vandalism, thereby ensuring the proper functioning of the door closing mechanism and improving overall building security.
Door Protection: Concealed door closers typically use an internal design that works closely with the door and frame. This allows for more even distribution of the closing force, reducing localized stress on the door and less the risk of deformation or damage over time, ultimately extending the door’s lifespan.
Dust and Moisture Resistance: Being installed inside the door or frame, concealed closers are less affected by external environmental factors. They are better protected from dust, moisture, and other contaminants, reducing the risk of malfunction due to corrosion or rust, and improving reliability and durability.
good Noise Reduction: Due to their enclosed internal structure and tighter connection with the door, concealed closers operate with significantly less noise. This makes them ideal for noise-sensitive environments such as hospitals, libraries, and conference rooms.
Name: Floor Spring, also known as Ground Closer or Floor Hinge.
Function: It is a type of automatic door closer installed beneath the door pivot, used for double-swing doors. It provides automatic closing and positioning functions.
Basic Configuration: Top pivot and bottom pivot (also called floor pivot). The top pivot is a component that connects the door frame and the door leaf at the upper part. It consists of a bolt-adjustable pin fixed to the door leaf and a pivot sleeve also mounted on the door leaf.
Working Principle:
Opening Process: When the door leaf is pushed open, it rotates around the axis of the top pivot and the connecting rod. The internal worm gear mechanism of the floor spring compresses the spring to store energy.
Closing Process: When released, the spring inside the floor spring releases energy, driving the worm gear to rotate in the opposite direction, thereby automatically closing the door. During this process, the hydraulic system controls the closing speed to provide cushioning and prevent a strong impact when the door shuts.
Positioning Principle: When the door is opened to 90°, the arched recess of the braking arm allows the door to remain at that position, functioning as a door stopper.
