The installation steps for the door shaft are as follows:
1. Preparation work
      Confirm the size of the door and door frame, select the appropriate door pivot, and usually match the length and load-bearing capacity of the door pivot with the size and weight of the door.
      Prepare installation tools such as drills, screwdrivers, wrenches, level gauges, plumb lines, etc.
2. Installation steps
(1) Determine the position of the door shaft: Mark the installation position of the door shaft at the corresponding position between the door frame and the door. Generally speaking, the door shaft should be installed at the edge of the door, and the upper and lower door shafts should be on a vertical line. You can use a plumb line and a level to ensure the correct position.
(2) Install the upper door shaft: Fix the fixing seat of the upper door shaft to the top of the door frame with screws or bolts. Ensure that the fixed seat is securely installed and the screws are tightened to prevent loosening. Some door hinges may require drilling holes on the door frame first, and then installing the fixing seat.
(3) Install the lower door shaft: At the installation position of the lower door shaft, first dig a suitable groove on the ground to place the base of the lower door shaft. Place the lower door shaft base into the groove, adjust its levelness with a spirit level, and then fix the base to the ground with concrete or other fixing materials. Be sure to leave enough space for the shaft of the door shaft to rotate freely.
(4) Install door shaft sleeve: Install the door shaft sleeve at the position corresponding to the door shaft at the edge of the door. The door shaft sleeve is usually fixed to the door with screws. It is necessary to ensure that the hole of the door shaft sleeve is aligned with the position of the upper and lower door shaft shafts, so that the door can be installed and rotated smoothly.
(5) Install the door: Lift the door up to align the door shaft sleeve with the shaft of the door shaft, then slowly lower the door and insert the door shaft sleeve into the door shaft sleeve. Check if the installation of the door is vertical and flat. If there is any deviation, it can be corrected by adjusting the position of the door shaft or shims.
(6) Adjustment and testing: After installation, conduct a door opening and closing test to check whether the door rotates smoothly and whether there is any jamming or friction. If there is a problem, it is necessary to adjust the position of the door shaft in a timely manner or check whether the door shaft sleeve is installed correctly. At the same time, check the fit between the closed door and the door frame. If there are any large gaps or other issues, corresponding adjustments need to be made.
3. Precautions
      During the installation process, it is necessary to strictly follow the installation instructions of the door shaft. Different types of door shafts may have different installation details.
      Ensure that the installation position of the door shaft is correct, otherwise it will affect the normal use and service life of the door.
      During the installation process, attention should be paid to safety to avoid personal injury caused by improper use of tools or accidental dropping of doors.
