The embodiment provides a door with a large opening.

In one embodiment, as shown in fig. 1 to 3, it comprises a door frame 2, a door leaf 5 and a door hinge. The outer side of the door leaf 5 is provided with a door guard plate 12 protruding out of the outer edge of the main body of the door leaf 5. The outer side of the door leaf 5 refers to the side of the door leaf 5 turned over when opened, and since the door is generally opened by turning the door leaf 5 to the outside, the side of the door leaf turned to the outside is simply referred to as the outer side of the door leaf for simplicity of description and compliance with industry habits. However, this is not meant to limit the use of the door, and the user may choose to set the door to open inwards, i.e. to rotate to open indoors, where the outside of the door leaf is referred to herein as the side facing indoors. The same is true for the internal and external descriptions of other components of the access door. The outermost side of the door leaf 5 can be provided with a door leaf flower plate 6; the outermost side of the door frame 2 can be provided with a wall protection flower plate 11 for decoration.

In the closed state, the door shield 12 shields the gap between the door frame 2 and the door leaf 5. It also comprises a door frame cassette 1 and a door leaf cassette 4. The door frame cassette 1 is arranged in the door frame 2; the door cassette 4 is arranged in the door 5; in the closed state, the door frame cassette 1 and the door leaf cassette 4 enclose a hinge accommodating space together; the door hinge is disposed in the hinge receiving space. The door hinge comprises a first hinge arm 10 and a second hinge arm 7. The first hinge arm 10 is hinged in the door leaf cassette 4 through the door leaf hinge shaft 8; the second hinge arm 7 is hinged in the door frame cassette 1 through a door frame hinge shaft 9; the first hinge arm 10 is hinged with the second hinge arm 7 through the middle hinge shaft 3; the part of the first hinge arm 10 close to the door leaf hinge shaft 8 is L-shaped; in the maximally open condition, the door leaf 5 is turned parallel to the door frame 2, and the door guard 12 adjacent to the first hinge arm 10 is accommodated inside the L-shaped structure of the first hinge arm 10.

When the device is opened, along with the rotation of the door leaf 5 relative to the door frame 2, the door hinge with the door leaf hinge shaft 8, the door frame hinge shaft 9 and the middle hinge shaft 3 can generate more free and flexible rotation, compared with the traditional door hinge with only one hinge shaft, the door leaf 5 of the device can not only carry out simple rotation displacement, but also generate displacement on the horizontal and vertical coordinates on an opening plane (namely, the overlook plane shown in fig. 1), thereby leading the root part of the door leaf 5 (namely, the door leaf and the hinge connecting part) not to generate interference collision with the nearby door frame 2 due to rotation only around a single shaft. The door hinge is rotated by the multiple shafts and is displaced along with the rotation shaft, and the rotation shaft is not required to be arranged on the exposed side surface of the root of the door leaf 5, and the door hinge is hidden in the door frame cassette 1 and the door leaf cassette 4, so that the door hinge has the function of preventing damage. However, the thickness of the door leaf 5 is limited, the door hinge hidden in the door body cannot be too large, that is, the length of the first hinge arm 10 and the second hinge arm 7 after being folded around the middle hinge shaft 3 is limited, so that the displacement of the horizontal and vertical coordinates of the door leaf 5 on the opening plane cannot be too large, and the door guard 12 protruding out of the outer edge of the door body is arranged to greatly increase the root rotation radius of the door leaf 5, so that interference collision is easily generated by the door hinge to reduce the opening degree of the door leaf 5. The device has the advantages that the L-shaped structure is arranged on the first hinge arm 10, so that the overturned door guard plate 12, particularly the door guard plate 12 overturned by 180 degrees, can be accommodated in the concave part of the L-shaped structure (shown in fig. 3), and the L-shaped first hinge arm 10 still keeps a small total length after being folded when the door leaf is closed, can be hidden in the door leaf cassette 4 (shown in fig. 1), and particularly avoids the increase of the thickness of the door leaf 5 due to overlarge folding size. Therefore, the door leaf 5 of the device not only can reach a large opening degree of 180 degrees, but also can ensure that the thickness of the door leaf 5 is not increased, and the door leaf is kept thin enough.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 1, the middle hinge shaft 3 is hinged at the middle of both the first hinge arm 10 and the second hinge arm 7; both the first hinge arm 10 and the second hinge arm 7 form a swinging section at a section away from the rotation axis with the middle hinge shaft 3 as a boundary. In the closed state, the swinging section of the first hinge arm 10 is positioned in the door frame cassette 1 and is abutted against the inner wall of the door frame cassette 1; the swinging section of the second hinge arm 7 is located in the door leaf cassette 4 and abuts against the inner wall of the door leaf cassette 4.

The swinging section is arranged and is abutted with the corresponding cassette in the closing state, so that the maximum angle of the door hinge on the closing stroke is limited by adding a simple structure on the basis of the prior structure, and finally, the door leaf 5 is ensured to be kept at the correct position when being closed. Although the door leaf 5 can rely on the butt with the door frame 2 to guarantee that the door body is correctly closed when closing, but the door of entering the family generally can set up great door crack and joint strip to play the wind-proof and sound insulation effect, therefore door leaf 5 and door frame 2 can not produce reliable butt, just need to restrict the maximum stroke of door hinge in order to guarantee the exact closed position of door leaf 5 at this moment.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 3, in the maximum open state, the end of the swing section of the first hinge arm 10 is located in the door frame cassette 1; the end of the swing section of the second arm 7 is located in the door leaf cassette 4.

Because the swinging section appears, the first hinge arm 10 and the second hinge arm present an X-shaped hinge structure, and the tail end of the swinging section swings freely, so that foreign matters are easy to hook in the opening and closing process of the door leaf 5, and further unsmooth opening and closing are caused. And under the maximum open state of the door leaf 5, the tail end of the swinging section is still hidden in the corresponding cassette, so that the tail end of the swinging section is prevented from swinging in an open environment, the probability of hooking foreign matters at the free swinging tail end in the opening process is reduced, and the use reliability of the door is improved.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 1 to 3, an inner protection plate 14 extending toward the opening of the door frame 2 is provided on the inner side surface of the door frame 2; in the closed state, the inner cover 14 covers the gap between the door frame 2 and the door leaf 5. The inner panel 14 on the inside, like the door panel 12 on the outside, provides protection against damage and wind and sound. However, since the door leaf 5 is opened toward the outside, the inner panel 14 located at the inside needs to be provided on the door frame 2 in order to avoid the obstruction of the opening.

In a preferred embodiment, based on the above embodiment, as shown in fig. 1 to 3, the door frame 2 is provided with a door panel accommodating groove 13 on the outer side surface, and in the closed state, the door panel 12 is accommodated in the door panel accommodating groove 13. The door guard 12 is accommodated in the guard accommodating groove 13, so that a gap between the door guard 12 and the outer side surface of the door frame is shielded by the guard accommodating groove 13, thereby preventing a destructor from inserting a hard object into the gap between the door guard 12 and the outer side surface of the door frame to tilt the door guard 12, exposing the gap between the door leaf 5 and the door frame 2, and further damaging the door hinge or the door lock. Similarly, when the inner panel 14 is provided, it is preferable that the inner side surface of the door 5 is provided with an inner accommodating groove 17; in the closed state, the inner panel 14 is accommodated in the inner accommodating groove 17.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 1 to 3, a shield seal 16 is provided between the door shield 12 and the shield accommodating groove 13. The sealing strip can prevent external strong wind from blowing into a room, has a warm keeping effect especially in winter, has a sound insulation effect, ensures that the room is quiet and prevents the conversation in the room from leaking from the door seam. Similarly, when the inner panel 14 and the inner vessel 17 are provided, the inner weather strip 15 is preferably provided between the inner panel 14 and the inner vessel 17.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 1 to 3, the outer side of the door frame 2 is flush with the outer side of the door leaf 5 in the closed state. When the door frame 2 is closed, the door leaf 5 is flush with the door frame, so that the appearance consistency of the entrance door can be improved, the door is relatively more attractive, and the user experience is improved. Similarly, in the closed state, the inner side surface of the door frame 2 is preferably flush with the inner side surface of the door leaf 5.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present utility model.
