In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0028] See also Figure 1-8 The utility model provides a technical solution: an anti-falling safety door, comprising a safety door body 1, a safety door frame 2 and a wall 3, the surface of the safety door frame 2 contacts the surface of the wall 3, the top and bottom of both sides of the safety door frame 2 are provided with a limiting mechanism 5, the top of the safety door frame 2 is provided with an insert block 6, and the top and bottom of both sides of the safety door frame 2 are fixedly connected with a fixing frame 12;

[0029] The limiting mechanism 5 includes a fixed block 501, a hexagonal hole 502, a threaded column 503 and a limiting plate 504. The surface of the fixed block 501 is fixedly connected to the surface of the safety door frame 2. The hexagonal hole 502 is opened inside the threaded column 503. The side of the threaded column 503 close to the fixed block 501 passes through the fixed block 501 and is connected to the internal thread of the fixed block 501.

[0030] In this embodiment: by moving the safety door frame 2 to the inside of the reserved hole in the wall 3, after leveling the safety door frame 2 and the safety door body 1, use an external screw to pass through the fixing frame 12 to fix the safety door frame 2, and the second limiting cone 13 on the surface of the fixing frame 12 will limit and prevent the external screw from loosening, and then rotate the threaded column 503 to make the first limiting cone 14 tightly bite with the surface of the wall 3, and then knock the plug block 6 upward to make the surface of the limiting plate 10 tightly contact with the inner wall of the limiting groove 11. At this time, the top of the safety door frame 2 will also be limited and reinforced, which can make the installation of the safety door frame 2 more stable, avoiding the problem that most of the existing methods for installing the safety door are to use expansion screws to connect and fix with the wall 3. After the safety door is opened and closed for a long time, the expansion screws are easy to loosen and fall off, causing the safety door to shake and fall off, posing a safety hazard.

[0031] As a technical optimization solution of the present invention, a bearing 9 is embedded in the interior of the limiting plate 504 , and the surface of the threaded column 503 is fixedly connected to the inner wall of the bearing 9 .

[0032] In this embodiment: the threaded column 503 is fixedly connected to the inner wall of the bearing 9. When the first limiting cone 14 contacts the wall 3, the threaded column 503 can continue to rotate, so that the first limiting cone 14 can continue to move to tightly engage with the surface of the wall 3, thereby achieving the effect of facilitating the threaded column 503 to continue to rotate after the first limiting cone 14 contacts the wall 3.

[0033] As a technical optimization solution of the present invention, a first limiting cone 14 is fixedly connected to the surface of the limiting disk 504 , and the number of the first limiting cones 14 is several and evenly distributed on the surface of the limiting disk 504 .

[0034] In this embodiment: by engaging the surface of the first limiting cone 14 with the surface of the wall 3, the safety door frame 2 and the safety door body 1 can be stably limited, achieving the effect of stably limiting the safety door frame 2 and the safety door body 1.

[0035] As a technical optimization solution of the present utility model, a second limiting cone 13 is fixedly connected to the surface of the fixing frame 12 , and the number of the second limiting cones 13 is several and evenly distributed on the surface of the fixing frame 12 .

[0036] In this embodiment, the second limiting cone 13 can limit the position of the external screw by contacting the surface of the external screw with the second limiting cone 13, thereby achieving the effect of limiting the position of the external screw.

[0037] As a technical optimization solution of the utility model, a through slot 7 is provided on the top of the safety door frame 2 , and the bottom of the insert block 6 passes through the through slot 7 and is movably connected with the inside of the through slot 7 .

[0038] In this embodiment, the inserting block 6 is movably connected to the inside of the through slot 7 so that the inserting block 6 can move, thereby achieving the effect of facilitating the movement of the inserting block 6 .

[0039] As a technical optimization solution of the utility model, a limiting groove 11 is opened inside the wall 3, and a limiting plate 10 is fixedly connected to the surface of the insert block 6. There are several limiting plates 10, and the surface of the limiting plate 10 is in close contact with the inner wall of the limiting groove 11.

[0040] In this embodiment: by knocking the insert block 6 upward, the surface of the limiting plate 10 is in close contact with the inner wall of the limiting groove 11. At this time, the top of the safety door frame 2 will also be limited and reinforced, achieving the effect of reinforcing the top of the safety door frame 2.

[0041] As a technical optimization solution of the present invention, a through hole 8 is opened inside the safety door frame 2 , and the positions of the fixing block 501 and the fixing frame 12 both correspond to the through hole 8 .

[0042] In this embodiment: since the through hole 8 corresponds to the position of the fixing block 501 and the fixing frame 12, the threaded column 503 and the external screw can be easily rotated through the through hole 8, thereby achieving the effect of facilitating the rotation of the threaded column 503 and the external screw.

[0043] As a technical optimization solution of the utility model, the inner wall of the through hole 8 is in close contact with the sealing cover 4 .

[0044] In this embodiment, the sealing cover 4 can cover the through hole 8 by contacting the sealing cover 4 with the inner wall of the through hole 8 , thereby achieving the effect of covering the through hole 8 .

[0045] Working principle: First, move the safety door frame 2 to the inside of the reserved hole in the wall 3. After leveling the safety door frame 2 and the safety door body 1, first use an external hexagonal wrench to insert the hexagonal hole 502 and rotate the threaded column 503 so that the surface of the first limiting cone 14 is in close contact with the surface of the wall 3. At this time, the safety door frame 2 and the safety door body 1 can be temporarily limited. Then use an external electric drill to drill a hole through the through hole 8, and then use an external expansion screw to pass through the fixing frame 12 to tighten the external screw so that the surface of the external screw is in close contact with the surface of the second limiting cone 13. The second limiting cone 13 can limit the external fixing screw to prevent the external screw from loosening due to the opening and closing vibration of the safety door body 1. Then rotate the threaded column 503 again to move the first limiting cone 14 to the surface of the second limiting cone 13. The surface of the wall 3 is tightly engaged, and then the insert block 6 is knocked upward so that the surface of the limiting plate 10 is in close contact with the inner wall of the limiting groove 11. At this time, the top of the safety door frame 2 will also be limited and reinforced, and the second limiting cone 13 is used to limit and prevent the external screws from loosening. The first limiting cone 14 is tightly engaged with the wall 3, which not only assists the installation of the safety door frame 2 but also increases the stability of the safety door frame 2. The insert block 6 and the limiting plate 10 reinforce the top of the safety door frame 2, which can make the installation of the safety door frame 2 and the safety door body 1 more stable, avoiding the problem that most of the existing methods of installing the safety door are to use expansion screws to connect and fix with the wall 3. After the safety door is opened and closed for a long time, the expansion screws are easy to loosen and fall off, causing the safety door to shake and fall off, posing a safety hazard.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
