The door frame is including the vertical strake 3 of right, last horizontal strake 4, the vertical strake 5 of left and the horizontal strake 6 down that end to end links together in proper order. The hinge comprises a first mounting ear 8 and a second mounting ear 9 pivotally connected together by a pivot pin 7. The second mounting lug is connected to the end face of the door panel in the width direction. First installation ear is connected on the terminal surface towards door plant width direction of vertical strake when the door plant is closed. The door panel is provided with an arc-shaped channel 10 with coaxial pins. The arc cover passes through the door panel through the arc passage. The clearance between the outer peripheral surface 11 of the arc-shaped cover and the arc-shaped channel is less than 0.8 mm. One end of the arc cover, which is positioned on the front surface of the door panel, is inserted on the right vertical edge strip and connected with the right vertical edge strip, and the other end of the arc cover is connected with one end of the connecting steel plate 12. The axle pin is located on the rear surface of the door panel. And the other end of the connecting steel plate is connected with a folded edge 13 which is turned towards the direction far away from the arc cover. The hem is connected to the right vertical edge strip by a connecting steel plate part mounting screw 14. The arc cover, the connecting steel plate and the right vertical edge strip enclose a vertical channel 15. The door stopper is installed in the vertical passageway. The radius of the circle on the outer peripheral surface of the arc-shaped cover is less than 20 cm. The height of the arc-shaped cover is more than 1.2 meters. The distance between the lower end face of the arc cover and the upper end face of the lower transverse edge strip is less than 2 mm. The first mounting ears are connected to the vertical edge strips by mounting ear mounting screws 16. The arc cover is provided with screw mounting operation holes 17 aligned with the mounting screws of the mounting lug parts. The diameter of the screw installation operation hole is 5 mm-10 mm. The screw mounting operation hole is provided with a rubber plug 18 in a penetrating way. The rubber stopper is pulled out when the mounting lug mounting screws 16 are mounted, and then the operation is performed through the bolt mounting operation holes. When the arc cover is installed, the arc cover penetrates through the arc channel from the rear side of the door to the front side and then is inserted into the installation groove in the right vertical edge strip, and then the folded edge is connected to the right vertical edge strip through a connecting steel plate part installation screw 14.
