4, door hinge:

4.1 door hinge should be able to hold door body weight, the door open 90 DHS process, door body should not produce tilt, door hinge axis should not produce greater than 2 mm displacement.

4.2 door hinge should convey move in 49 flexible, N pull force can be under flexible rotation 90 DHS door. Folding doors (or root) the hinge on 49 N force, should open, its overall contraction movement should be consistent. After folding doors, and its neighboring sectoral level of the difference between the two should not be greater than 2 mm.

4.3 door hinges on the strength should be can withstand use ordinary mechanical hand tools, implementation of hinge impact neither destroyed to cut the impact of the hinge and pry grilled torque in the required time, door hinge should be no fault phenomenon. The welding and welding shall not be higher than the hinge surface.

4.4 door hinge joints and doors and in the 6000 N pressure under the action of forces role, direction for door open direction, the frame fits to the door leaf shall not produce more than 8 between the displacement, door mm fan should not be greater than 5 mm produced the concave deformation.

5, locks:

5.1 anti-theft lock machinery

Security guard against theft install on door lock FuQuan GA/T73 minimum should be A level of mechanical technical requirements of the anti-theft lock. The drawings shall indicate on the selection of mechanical product model and anti-theft lock factory name.
