In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Examples

As shown in fig. 1 to 5, the door body provided in this embodiment includes a door frame 10 and a door leaf 20 rotatably connected to the door frame 10; the edge of the door leaf 20 facing the door frame 10 is provided with a door leaf frame 22, two sides of the door leaf frame 22 along the thickness direction of the door leaf 20 are respectively provided with a first pressing surface 2211, and two sides of the door frame 10 along the thickness direction of the door leaf 20 are respectively provided with a second pressing surface 11; when the door 20 is closed, the first pressing surface 2211 and the second pressing surface 11 located on the opposite sides in the thickness direction of the door 20 can be press-fitted to each other.

The door 20 includes a door core 21, and door frames 22 are coated on two sides of the door core 21 along a width direction of the door 20.

Specifically, an opening for arranging the door body is reserved on the wall body, and the door frame 10 is coated on two sides of the opening, so that the attractiveness and firmness of the opening are improved. The door leaf 20 is hinged to the door frame 10 to facilitate the opening and closing of the door leaf 20. The door leaf 20 includes door core 21 and door leaf frame 22, and door leaf frame 22 cladding is in the edge of door core 21 towards door frame 10, and then strengthens the fastness of door core 21 combination and forms the holistic structurality of door leaf 20 through door leaf frame 22. Meanwhile, the door leaf frame 22 can cover the edge of the door core 21 to protect the door core 21, so that the situation that the edge of the door core 21 is warped and the like is effectively avoided, seamless covering of the edge of the door core 21 is realized, and the structural stability of the door leaf 20 is improved.

In actual use, the door frame 22 is provided with first pressing surfaces 2211 on both sides in the thickness direction of the door 20, and the door frame 10 is provided with second pressing surfaces 11 on both sides in the thickness direction of the door 20. When the door leaf 20 is closed, the first pressing surface 2211 on the same side can be tightly attached to and pressed against the second pressing surface 11 on the door frame 10, and then a sealed pressing area is formed on each of two sides of the door leaf 20 in the thickness direction, that is, two sealed pressing areas extending along the length direction of the door leaf 20 are arranged between the door leaf 20 and the door frame 10, so that the sealing performance between the door leaf 20 and the door frame 10 is improved.

The door body structure realizes seamless cladding of the edge of the door core 21 by cladding the door leaf frame 22 at the edge of the door core 21, increases the installation precision and further reduces the installation gap between the door leaf 20 and the door frame 10; meanwhile, the first pressing surface 2211 and the second pressing surface 11 act together to increase the sealing performance between the door leaf 20 and the door frame 10 and reduce the gap between the door leaf and the door frame. In addition, when a thief uses the gap between the door leaf 20 and the door frame 10 to pry the door, the gap between the door leaf 20 and the door frame 10 is reduced by the pressing fit of the first pressing surface 2211 and the second pressing surface 11 on the same side, so that there is no space for prying, that is, a prying tool such as a crowbar can hardly be inserted between the door leaf 20 and the door frame 10, and the safety of the door body is further improved.

With continued reference to fig. 1-3, preferably, a first sealing strip 31 is disposed between the first pressing surface 2211 and the second pressing surface 11 on the same side; the first sealing strips 31 are a group and are fixedly arranged on the first pressing surface 2211 or the second pressing surface 11; or two groups of first sealing strips 31 are respectively and fixedly arranged on the first pressing surface 2211 and the second pressing surface 11.

Specifically, a first extending portion is disposed on one side of the door frame 22 along the thickness direction of the door core 21, the first extending portion horizontally extends toward one side of the door frame 10 along the width direction of the door core 21, and the first pressing surface 2211 is disposed on one side of the first extending portion parallel to the width direction of the door frame 10. A second extending portion is disposed on a side of the door frame 10 opposite to the first extending portion, the second extending portion extends horizontally along a side facing the door core 21, and the second pressing surface 11 is disposed on a side surface of the second extending portion parallel to the door core 21.

Meanwhile, the first pressing surface 2211 is fixedly provided with a first sealing strip 31, the first sealing strip 31 extends along the length direction of the door core 21, and the second pressing surface 11 is also fixedly provided with the first sealing strip 31. When the door leaf 20 is closed, the first sealing strip 31 on the first extending portion is pressed on the second pressing surface 11 on the same side, and meanwhile, the first sealing strip 31 on the second extending portion is pressed on the first pressing surface 2211 on the same side, so that two first sealing strips 31 are respectively arranged on two sides of the door leaf 20 in the thickness direction, two seals between the door leaf 20 and the door frame 10 are formed, and the sealing performance between the two seals is further improved.

Further, since there is no gap between the first weather strip 31 and the door frame 10 and between the first weather strip 31 and the door frame 22 due to the pressing action of the first weather strip 31, there is no point of force when the door is pried by using a tool such as a crowbar, and thus the safety between the door 20 and the door frame 10 is improved.

In practical use, a T-shaped slot is disposed on the first extending portion of the door frame 22, and an inverted T-shaped slot is disposed on the second extending portion of the door frame 10, so as to install the corresponding first sealing strip 31 in the slot.

In an alternative of this embodiment, as shown in fig. 1, fig. 2 and fig. 5, the door frame 22 includes a first frame 221 and a second frame 222 respectively disposed on two sides of the door 20 in the width direction, the first frame 221 is located on one side of the door 20 rotatably connected to the door frame 10, and the first pressing surface 2211 is located on the first frame 221.

Specifically, the first frame 221 and the second frame 222 are disposed opposite to each other at an interval and are disposed on two sides of the door core 21, the first frame 221 is wrapped on one side of the door core 21 connected to the door frame 10, and the second frame 222 is wrapped on one side of the door core 21 away from the door frame 10, so that the structural performance of the door core 21 is improved by the first frame 221 and the second frame 222.

In practical use, since the connecting member such as the hinge 40 is disposed on the side where the door 20 is connected to the door frame 10, in order to facilitate the installation of the hinge 40 and the rotation of the door 20 around the connecting point with the door frame 10, a gap between the door and the door frame may increase, the first pressing surface 2211 is disposed on the first frame 221, and is simultaneously matched with the first sealing strip 31 to be pressed on the door frame 10. Since the first weather strip 31 has a certain thickness, the gap between the door 20 and the door frame 10 can be sufficiently filled, and the sealing property and the safety of the connection therebetween can be increased.
