[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1:

[0033] Figures 1 to 5 The first embodiment of the door and window system with an anti-falling corner function of the present invention is shown, comprising a door frame 1, a sash frame 2 and a sash body 3. The sash body 3 is installed in the sash frame 2, and one side of the sash frame 2 is movably hinged to one side of the door frame 1 through a hinge 4. A load adaptor 5 is provided between the bottom of the sash body 3 and the sash frame 2 to collect the uniformly distributed load q added by the gravity G of the sash body 3 to the bottom of the sash frame 2 to the side close to the hinge 4. During installation, the sash body 3 is installed in the sash frame 2, and then the door frame 1 is installed, and then one side of the sash frame 2 is movably hinged to one side of the door frame 1 through a hinge 4, and the load adaptor 5 is installed between the bottom of the sash body 3 and the sash frame 2. Compared with the traditional structure, the load adaptor 5 can gather the uniformly distributed load q added to the bottom of the sash frame 2 by the gravity G of the sash body 3 to the side close to the hinge 4. In other words, the traditional uniformly distributed load q is gathered to the side close to the hinge 4 to form a load concentration area. The load concentration area is close to the hinge 4. On the one hand, it greatly reduces the load on the side of the bottom of the sash frame 2 away from the hinge 4; on the other hand, it shortens the force-bearing length of the bottom of the sash frame 2, reduces the lever arm and the bending moment, thereby realizing the function of anti-falling angular displacement, and the overall structure is simple and reliable.

[0034] In this embodiment, the load adaptor 5 is arranged on the side close to the hinge 4. This arrangement makes the load concentration area close to the hinge 4 side, which greatly reduces the load on the side of the bottom of the sash frame 2 away from the hinge 4 on the one hand; on the other hand, it reduces the force-bearing length of the bottom of the sash frame 2, reduces the force arm and bending moment, thereby realizing the function of preventing the angular displacement of falling, and the overall structure is simple and reliable.

[0035] In this embodiment, an empty gap 6 is formed between the bottom of the fan body 3 and the fan frame 2 on the side away from the hinge 4. In this way, a structure is formed in which the near hinge end actually receives force and the far hinge end does not receive force, further ensuring the effect of preventing the angle displacement from falling.

[0036] In this embodiment, the load adapting member 5 is configured as a hard pad, which can ensure that the fan body 3 and the fan frame 2 are in rigid contact with the hard pad, thereby improving the load collection effect.

[0037] In this embodiment, the load adaptor 5 is configured as a movable block that can move on the side close to the hinge 4. The movable block is configured as a movable block, which can be adaptively adjusted, and is also for improving the load concentration effect.

The jacking screw 54 is rotated, and the jacking screw 54 is lifted and lowered, thereby adjusting the height and improving the load collection effect.

[0044] Embodiment 5:

[0045] like Fig. 9As shown, the fifth embodiment of the door and window system with an anti-falling function of the present invention is basically the same as the embodiment 1, except that: in this embodiment, the contact surface length between the load adaptor 5 and the fan body 3 is greater than the contact surface length between the load adaptor 5 and the fan frame 2. This arrangement takes into account both the center of gravity adjustment and the increase in the contact area with the bottom of the fan body 3.

[0046] Embodiment 6:

[0047] like Fig.10 and Fig.11 As shown, the sixth embodiment of the door and window system with the function of preventing corner falling of the present invention is basically the same as the embodiment 1, and the only difference is that in this embodiment, the bottom of the sash body 3 and the sash frame 2 form a virtual connection on the side away from the hinge 4 through the flexible pad 7. In this way, a structure is formed in which the near hinge end actually receives force and the far hinge end is virtually connected without force, which further ensures the effect of preventing corner falling displacement.
