       The core application of the door shaft is to achieve the rotation and opening and closing of the door/cover. It is used in all scenarios involving openable and closable structures, covering multiple basic industries. The concentrated areas of use are as follows:
1. Construction and Home Furnishing Industry
       The doors and windows (wooden doors, anti-theft doors, aluminum alloy windows), indoor partition doors, and fire doors of civil buildings ensure that the door shafts can open and close flexibly and remain stable for a long time.
       The wardrobe doors, cabinet doors, and storage cabinet doors in home furniture often use small silent door shafts, which are suitable for daily high-frequency opening and closing needs.
       Glass doors, sliding doors, and emergency access doors in public buildings are commonly equipped with heavy-duty or load-bearing door shafts to meet the requirements of multi person use and safety protection.
2. Industrial manufacturing industry
       The cabin doors, maintenance doors, and observation windows of industrial equipment, such as machine tool protective cover doors, distribution box cabinet doors, boiler maintenance doors, and door shafts, need to be adapted to equipment high temperature, vibration, and other working conditions.
       The warehouse gates, container doors, and cold storage doors of warehousing and logistics adopt heavy-duty load-bearing door shafts to support the stable opening and closing of large-sized and heavy-duty door bodies.
       The sealing doors and isolation doors of specialized equipment, such as clean room doors and laboratory protective doors, require the door shaft to cooperate with the sealing structure to ensure the sealing performance after closure.
3. Transportation industry
       Vehicle categories: car doors, trunk doors, engine covers, passenger doors and equipment maintenance doors for rail transit vehicles, cabin doors and deck doors for ships, door shafts that need to consider earthquake resistance, wear resistance, and lightweight.
       Transportation facilities: toll station access doors, parking lot barrier shafts, tunnel inspection doors, suitable for outdoor harsh environments (high temperature, rain and snow).
4. Special and livelihood industries
       Security and Fire Protection: Security doors, explosion-proof doors, fireproof rolling shutter doors, and door shafts must have anti pry, high temperature resistance, and impact resistance to ensure safety and protection effects.
       Medical and catering: Ward doors and operating room doors in hospitals, kitchen cabinet doors and refrigerator doors in the catering industry, and door shafts must meet hygiene, easy cleaning, and noise reduction requirements.
       Outdoor facilities: Public restroom doors, park rest pavilion doors, community access doors, suitable for frequent outdoor use and changing weather scenarios.
