When the anti-falling structure is installed, the stopper 400 is stuck between the upper horizontal base plate 211 and the other extension 112, that is, the stopper 400 is in the upper gap; the hook head 610 of the elastic positioning hook 600 is hooked into the upper plate member fixing In the positioning groove 2111, another extension portion 112 is inserted into the slot 301; when the positioning member 700 fixing the upper base plate member 210 and the door and window frame 1001 falls off or is lost, the anti-falling structure can prevent the upper horizontal base plate 211 from moving relative to the door and window frame 1001, which can prevent the upper base plate member 210 of the upper hinge member from falling off from the door and window frame 1001, that is, it can prevent the door and window sash 1002 connected to the upper base plate member 210 from falling off from the door and window frame 1001.

[0146] The lower horizontal substrate 221 of the lower substrate member 220 is inserted between the groove bottom surface 1112 of the groove body 111 of the installation groove 110 and one of the extensions 112. There is a lower gap between the lower horizontal substrate 221 and the other extension 112. When the anti-falling structure is installed, the stopper 400 is inserted between the lower horizontal substrate 221 and the other extension 112, that is, the stopper 400 is in the lower gap; the hook head 610 of the elastic positioning hook 600 is hooked into the positioning groove 221 of the lower plate member. 1, the other extension part 112 is inserted into the slot 301; when the positioning member 700 fixing the lower base plate member 220 and the door and window frame 1001 falls off or is lost, the anti-falling structure can prevent the lower horizontal base plate 221 from moving relative to the door and window frame 1001, which can prevent the lower base plate member 220 of the lower hinge member from falling off from the door and window frame 1001, that is, it can prevent the door and window sash 1002 connected to the lower base plate member 220 from falling off from the door and window frame 1001.

[0147] In the installation process of the existing door and window frames and door and window sashes, especially when the upper base plate of the upper hinge component is installed on the door and window frame, the installer needs to hold the upper base plate alone and then install the upper screws, which is troublesome; in order to quickly install the upper base plate of the upper hinge component on the door and window frame, a companion is required to hold the upper base plate. This results in the need to arrange two installers during the installation process of the existing door and window frames and door and window sashes. The anti-falling structure of the present invention can make the upper horizontal base plate 211 unable to move relative to the door and window frame 1001, and the anti-falling structure has a holding force, that is, the setting of the anti-falling structure can keep the upper horizontal base plate 211 in the door and window frame 1001, so that the upper horizontal base plate 211 is positioned in the door and window frame 1001, and then the installation of the positioning member 700 and other operations are performed, which is very convenient. With the anti-falling structure of the present invention, when the upper base plate 210 is installed on the door and window frame 1001, generally only one installer is needed to complete the operation. The anti-falling structure installed at the lower horizontal base plate 221 also has a retaining force.

[0148] The elastic positioning hook 600 includes a hook connecting plate 620, one end of which is connected to the stopper 400, and the other end of the hook connecting plate 620 is provided with a hook head 610; the sum of the width of the stopper 400 and the width of the support member 300 is greater than the width of the hook connecting plate 620.

[0149] The sum of the width of the blocking member 400 and the width of the supporting member 300 is equal to the width of the anti-falling structure; when the anti-falling structure is installed between the inner wall 1111 of the groove body 111 and the upper horizontal substrate 211, the width of the anti-falling structure is equal to the distance between the inner wall 1111 of the groove body 111 and the upper horizontal substrate 211, and the width of the hook connecting plate 620 enables the elastic positioning hook 600 to be deformed between the inner wall 1111 of the groove body 111 and the upper horizontal substrate 211 when inserted between the inner wall 1111 of the groove body 111 and the upper horizontal substrate 211, until the hook head 610 of the elastic positioning hook 600 is hooked into the upper plate positioning groove 2111, and the elastic positioning hook 600 returns to its original state, and the elastic positioning hook 600 is hung on the upper horizontal substrate 211, and at this time, the anti-falling structure will not move outward. Subsequently, the positioning member 700 is installed so that the positioning member 700 is inserted into the installation groove 110. The positioning member 700 can block the path for the anti-drop structure to move outward, and the positioning member 700 acts as a stopper. The process of hooking the elastic positioning hook 600 into the lower plate positioning groove 2211 is the same as the process of hooking the elastic positioning hook 600 into the upper plate positioning groove 2111. The structure of the elastic positioning hook 600 makes it easy for the elastic positioning hook 600 to deform, so that the hook head 610 can be stuck in the upper plate positioning groove 2111 and the lower plate positioning groove 2211. The elastic positioning hook 600 is inserted between the inner wall 1111 of the groove body 111 and the upper horizontal base plate 211.

[0150] A stopper 2212 is provided on the lower horizontal substrate 221, and the stopper 2212 is arranged along the length direction of the lower horizontal substrate 221. The distance between the side 420 of the stopper 400 away from the support member 300 and the side 320 of the support member 300 away from the driving member 500 is equal to the distance between the bottom surface 22121 of the stopper 2212 and the bottom surface 2213 of the lower horizontal substrate 221. When an anti-drop structure is provided between the inner wall 1111 of the slot body 111 and the lower horizontal substrate 221, the stopper 400 can be stuck between the stopper 2212 and the slot bottom surface 1112 of the slot body 111, so that the position of the anti-drop structure is more stable.

[0151] A notch 410 is provided on one side 420 of the stopper 400 away from the support member 300, and the notch 410 extends to one end of the stopper 400 away from the driving member 500; the side 420 of the stopper 400 away from the support member 300 is a plane; the notch 410 has a first inclined surface 411, and the angle A formed by the first inclined surface 411 and the side 420 of the stopper 400 away from the support member 300 is an obtuse angle. The notch 410 makes it easier for the stopper 400 and the hook elastic positioning hook 600 to deform. The provision of the first inclined surface 411 can facilitate the anti-drop structure stopper 400 to penetrate between the limiting portion 2212 and the groove bottom surface 1112 of the groove body 111, thereby improving the installation efficiency.

[0152] The end of the support member 300 close to the hook head 610 has a second inclined surface 311 inclined relative to the plug-in side portion 310 of the support member 300; the plug-in side portion 310 of the support member 300 is a plane; the angle B formed by the second inclined surface 311 and the plug-in side portion 310 of the support member 300 is an obtuse angle. The second inclined surface 311 is provided to facilitate the support plate to be inserted between the groove bottom surface 1112 of the groove body 111 and the extension portion 112.

[0153] A third inclined surface 510 is provided at the connection between the side of the driving member 500 away from the support member 300 and the stopper 400; the side of the driving member 500 away from the support member 300 is a plane; an angle C between the third inclined surface 510 and the side of the driving member 500 away from the support member 300 is an obtuse angle. The third inclined surface 510 is provided so that when the anti-drop structure is installed or removed, the staff can push the driving member 500 more conveniently.

[0154] An upper plate positioning groove 2111 is provided at the connection between the upper horizontal base plate 211 and the upper vertical base plate 212. This structure enables the anti-falling structure to support most of the upper horizontal base plate 211 in the length direction, so that the anti-falling effect is better.

The first upper positioning portion 213 is provided with a first upper positioning hole 2131 for inserting the positioning member 700. The distance L1 between the first upper positioning hole 2131 and the upper vertical substrate 212 is greater than the length L2 of the anti-drop structure of the door and window. This structure ensures that the anti-drop structure inserted between the upper horizontal substrate 211 and the corresponding extension portion 112 does not affect the installation of the positioning member 700, so that the positioning member 700 and the anti-drop structure achieve a double anti-drop effect on the upper side of the door and window.

[0156] A lower plate positioning groove 2211 is provided at the connection between the lower horizontal base plate 221 and the lower vertical base plate 222. This structure enables the anti-falling structure to support most of the area of ​​the lower horizontal base plate 221 in the length direction, so that the anti-falling effect is better.

[0157] A first lower positioning portion 223 is provided at one end of the lower horizontal substrate 221 away from the lower vertical substrate 222. The first lower positioning portion 223 is provided with a first lower positioning hole 2231 for inserting the positioning member 700. The distance L3 between the first lower positioning hole 2231 and the lower vertical substrate 222 is greater than the length L2 of the anti-drop structure of the door and window. This structure ensures that the anti-drop structure inserted between the lower horizontal substrate 221 and the corresponding extension portion 112 does not affect the installation of the positioning member 700, so that the positioning member 700 and the anti-drop structure achieve a double anti-drop effect on the lower side of the door and window.

[0158] The first lower positioning hole 2231 is provided on the first lower positioning surface 2232 of the first lower positioning portion 223. The angle formed by the first lower positioning surface 2232 and the lower horizontal substrate 221 is an acute angle. The first lower positioning surface 2232 is perpendicular to the central axis of the first lower positioning hole 2231. This structure facilitates the positioning member 700 to be obliquely inserted into the mounting groove 110 after passing through the first lower positioning hole 2231, so that the connection between the positioning member 700 and the door and window frame 1001 is more stable.

[0159] The anti-drop structure of the door and window inserted between the upper horizontal base plate 211 and the corresponding extension 112 is the upper anti-drop structure, and the anti-drop structure of the door and window inserted between the lower horizontal base plate 221 and the corresponding extension 112 is the lower anti-drop structure; the upper anti-drop structure is mirror-symmetrical with the lower anti-drop structure. This structure enables the upper anti-drop structure and the lower anti-drop structure to be both arranged on the same side in the width direction of the mounting groove 110, so that the anti-drop effect is better. In this embodiment, the upper anti-drop structure and the lower anti-drop structure are both located on the side of the mounting groove 110 in the width direction close to the outside of the room.

[0160] When the door handle inside the door and window room is on the left, the upper anti-drop structure is the first type of anti-drop structure, and the lower anti-drop structure is the second type of anti-drop structure; when the door handle inside the door and window room is on the right, the upper anti-drop structure is the second type of anti-drop structure, and the lower anti-drop structure is the first type of anti-drop structure. In this embodiment, the door handle inside the door and window room is on the left.
