Embodiment Construction
[0049] now refer to Figure 1 to Figure 25 Let's describe a specific embodiment.
[0050] In the double-leaf safety door in the first embodiment, the upper fan frame 7 and the lower fan frame 8 of its gauze fan 2 are the same as the cross-section of the hinge side fan frame 6; Go out other three fan frames (the thickness of lock side fan frame 5 is thicker than the thickness of upper fan frame 7, lower fan frame 8 and hinge side fan frame 6), see Figure 6 . figure 1 It is the front view of the first embodiment of the double-leaf safety door of the present invention; figure 2 It is the back view of the first embodiment of the double-leaf safety door of the present invention; image 3 It is a perspective view of the first embodiment of the double-leaf safety door of the present invention when it is opened. Such as figure 1 and figure 2 Shown, it is door frame 1 and gauze fan 2 when viewed from the front; Such as image 3 As shown, it can be seen that two fans (gauze...

Abstract
The invention discloses a dual-door-leaf safety door and a screen door. Rotating shafts of two door leaves of the dual-door-leaf safety door are located on a door frame on the same side, the opening directions of the door leaves are the same, and the closed door leaf is independently opened and closed or opened and closed along with the screen door leaf. The first side of the front portion of a section structure of a lock side door leaf frame is used for fixing a screen, a lock pin hole is formed in the fourth side of the rear portion of the section structure, the fourth side is the locking surface of the lock edge side face of the closed door leaf, a step is arranged between the front and rear portions of the section structure, and the side, close to the door frame, of the section structure is the first side face which is the locking surface of the door frame. The section of a hinge side door leaf frame is rectangular, the side, close to the screen, of the hinge side door leaf frame is the second side face used for fixing the screen, and the size of the second side face is identical to that of the first side. The second side, attached to the closed door leaf, of the hinge side door leaf frame and the step of the lock side door leaf frame are on the same plane, and the second side is locked to the lock side door leaf frame.

Background technique [0002] One of the existing technologies is to open one or two air vents on the anti-theft door leaf, then install a small door on the air vent, install gauze on the air vent, open the small door to ventilate, and close the small door to keep warm and secure. effect. But the shortcoming of this kind of door is that the ventilation area is little; Furthermore, when the wicket is in the open state, the wicket also shakes together when the gate is opened and closed, which is impersonal. The other is two independent door leaves, one is a ventilation fan, the other is a closed leaf, one opens inward and the other opens outward. The disadvantage of this kind of door is that the door frame is too wide, uses a lot of materials, occupies a large area, and is not dexterous. C...
