Detailed Description

A specific embodiment will now be described with reference to fig. 1 to 13.

Fig. 3 to 7 show the case where the screen door leaf 21 is mounted on the door frame 11. The door frame 11 is fixedly connected with the wall 10, and the outer fastening edge 19 of the door frame 11 is fastened on the outer wall 10 to cover the seam between the outer wall 10 and the door frame 11. The hinge of the door is 13, and the door leaf 9 is blocked by the door stop surface 20 on the door frame of the door and can not be opened outwards, but can be opened inwards. The locking pin 15 on the door leaf 9 enters the door frame 11 to lock the door.

As can be seen from fig. 3, 4, 5 and 7, the screen door 21 is attached to the reinforcing surface 17 of the door frame 11 with hinges 8, the cover surface 5 of the screen door 21 abuts against the transition surface 26 of the door frame 11 when closed via a weather strip (not shown), and the lock pin 16 of the screen door enters the door frame 11 to lock the door. If the door frame is too narrow, the handle of the door will touch the screen door 21, and then the screen door 21 can be drilled next to the door handle 25, i.e. the handle box hole 27, to let the handle 25 go through, and for safety and aesthetic reasons, a handle box 22 is made and placed at the handle box hole 27, and then fixed, and the hole 27 and the handle 25 are covered, as shown in fig. 3 and 4.

In order to make the screen door leaf 21 and the door have a harmonious and integrated feeling, an inclined surface 6 is designed from the cover surface 5 of the screen door leaf 21 to one end of the center of the door leaf and gradually transits to the outermost panel 7 of the screen door leaf. Design like this, reduced screen door leaf own door frame thickness, both reduced the protrusion like this, played save material, do not too much occupy the space in public corridor.

The first embodiment is that the sash around the sash 21 is a profile, see fig. 5, 6 and 9. The screens 1 in the front, back and middle of the profile are not in one plane. The gauze screen 1 is put into the screen clamping groove 18 of the lock side leaf frame, the hinge side leaf frame, the upper leaf frame and the lower leaf frame, the four leaf frames are cut into the size and the four corners are fixedly connected, and then the gauze screen is fixedly connected, and the gauze door leaf is finished. The estimation may be welding or riveting, etc.

A second embodiment is that the panels of the sash around the door leaf 21 and the intermediate screen 1 are a metal sheet and the panels 7 and the intermediate screen 1 are in one plane, see fig. 10. The leaf frame panels 7 around the screen door leaf 21 and the screen 1 in the middle are a metal plate, and the other metal plate is folded into 28, a back plate and the like, so that the front metal plate and the rear metal plate are connected in an occlusion way to form the screen door leaf.

Fig. 11 shows a third embodiment of the yarn door leaf according to the invention, without the cover, the first side and the second side, the inclined plane being directly connected to the side.

Fig. 12 shows a fourth embodiment of the yarn door leaf of the present invention, wherein the first and second faces are absent from the leaf frame and the inclined face is directly connected to the cover face.

Fig. 13 shows a fifth embodiment of the screen door leaf according to the present invention, wherein the screen and the panel are a metal plate, and the screen door leaf is formed by bending or pressing, the screen is formed by punching a hole in the middle of the metal plate, and the screen and the panel are not on the same plane.

In a word, the yarn door leaf is adorned on the reinforced face of door frame, and the structure of fan frame is passed through the inclined plane slope passes through to the panel, makes harmonious transition between yarn door leaf and the door to make yarn door leaf and door wholly draw one, pleasing to the eye harmonious, no matter yarn door leaf intermediate structure is how, as long as pass through the inclined plane transition all falls within the utility model discloses within the required protection.
