Description

Technical Field

[0001] This utility model relates to the field of adjusting the opening angle of security doors, specifically a security door with adjustable opening angle. Background Technology

[0002] The hinges of security doors are generally C-shaped. This type of hinge restricts the opening angle of the security door, which can generally only be turned outwards by 90 degrees. Therefore, if the corridor of the community is narrow, the security door will block most of the corridor after it is opened, making it inconvenient for other residents on the same floor to walk. Secondly, the blocked corridor also makes it inconvenient for users to move furniture, which is quite troublesome. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable-opening security door in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-opening security door, comprising a door frame connected to a wall, an embedded hole on one side of the inner wall of the door frame, a concealed box embedded in the inner wall of the embedded hole, a hinge with a "C" shaped structure rotatably mounted on the inner wall of the concealed box, an adjustment mechanism rotatably mounted at the end of the hinge, the longitudinal plate of the hinge being connected to the adjustment mechanism through a limiting mechanism, and the adjustment mechanism being fixedly connected to the side wall of the security door.

[0005] As a further embodiment of this utility model: the adjustment mechanism includes a receiving groove formed on the horizontal plate at the end of the hinge, and a rotating plate is rotatably installed on one end of the receiving groove, and the rotating plate is fixedly connected to the side wall of the security door.

[0006] As a further improvement of this utility model: the limiting mechanism includes a countersunk hole and a through hole formed on the longitudinal plate of the hinge, and the countersunk hole and the through hole are connected.

[0007] As a further improvement of this utility model, the limiting mechanism also includes a threaded hole at one end of the rotating plate, and the rotating plate, when rotated to be parallel to the horizontal plate at the end of the hinge, causes the threaded hole to align with the through hole.

[0008] As a further improvement of this utility model, the limiting mechanism further includes a limiting bolt, which passes through a countersunk hole and a through hole and is threadedly connected to the threaded hole. The countersunk hole is used to accommodate the end head of the limiting bolt.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By setting a limiting mechanism and an adjusting mechanism, when the security door is opened 90 degrees outward and obstructs the corridor, the limitation mechanism can be removed from the adjusting mechanism, allowing the security door to be opened 180 degrees, which facilitates the handling of clamps. When furniture is not being moved, if the security door is opened 90 degrees and does not obstruct the corridor, the limiting mechanism can be used again to limit the adjusting mechanism, ensuring that the door can only be opened 90 degrees.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 In this embodiment of the utility model, an adjustable-opening security door includes a door frame 1 connected to a wall. An embedded hole 3 is provided on one side of the inner wall of the door frame 1. A hidden box 4 is embedded in the inner wall of the embedded hole 3. A hinge 5 with a "C" shaped structure is rotatably installed on the inner wall of the hidden box 4. An adjustment mechanism is rotatably installed at the end of the hinge 5. The longitudinal plate of the hinge 5 is connected to the adjustment mechanism through a limiting mechanism. The adjustment mechanism is fixedly connected to the side wall of the security door 2.

[0017] In this embodiment: First, when the security door 2 is opened, the limiting mechanism is in a state of restricting the adjustment mechanism. The security door 2 can be rotated outward and opened 90 degrees. When moving furniture or when the corridor is narrow, in order to avoid the security door 2, which is rotated outward and opened 90 degrees, from blocking the corridor and making it inconvenient to move the clamps, the limitation mechanism on the adjustment mechanism can be removed. At this time, the security door 2 can be opened outward again by 90 degrees. At this time, the security door 2 is rotated outward and opened to 180 degrees, which can avoid the security door 2 from blocking the corridor and also facilitate the movement of the clamps.

[0018] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The adjustment mechanism includes a receiving groove 7 opened on the horizontal plate at the end of the hinge 5, and a rotating plate 6 is rotatably installed on one end of the inner side of the receiving groove 7. The rotating plate 6 is fixedly connected to the side wall of the security door 2.

[0019] In this embodiment: after the security door 2 is opened by 90 degrees outward, when it needs to be opened by 90 degrees outward again, the restriction of the limiting mechanism on the adjusting mechanism is removed. At this time, the security door 2 can be pushed outward again. The security door 2 then drives the rotating plate 6 and the end horizontal plate of the hinge 5 to rotate relative to each other, so that the security door 2 can be opened to 180 degrees, thus not obstructing the corridor.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The limiting mechanism includes a countersunk hole 8 and a through hole 9 on the longitudinal plate of the hinge 5. The countersunk hole 8 and the through hole 9 are connected. The limiting mechanism also includes a threaded hole 10 on one end of the rotating plate 6. When the rotating plate 6 is rotated to be parallel to the transverse plate at the end of the hinge 5, the threaded hole 10 and the through hole 9 are aligned. The limiting mechanism also includes a limiting bolt 11. The limiting bolt 11 passes through the countersunk hole 8, the through hole 9 and the threaded hole 10 and is threadedly connected. The countersunk hole 8 is used to accommodate the end head of the limiting bolt 11.

[0021] In this embodiment: When removing the restriction of the limiting mechanism on the adjusting mechanism, a hexagonal wrench is used to connect with the hexagonal hole at the end of the limiting bolt 11, and the limiting bolt 11 is rotated using the hexagonal wrench. At this time, the limiting bolt 11 is loosened until the limiting bolt 11 is completely removed, thus removing the restriction of the limiting mechanism on the adjusting mechanism. After the furniture is moved, if the security door 2 is opened 90 degrees, it will not obstruct the corridor. At this time, the security door 2 is rotated to the 90-degree open state. At this time, the security door 2 drives the rotating plate 6 to reset. The limiting bolt 11 is passed through the countersunk hole 8 and the through hole 9, and then threadedly connected to the threaded hole 10 again, thus limiting the adjusting mechanism again, so that the security door 2 can only be opened 90 degrees.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
