Further:

at least one slot is respectively arranged on the first step part along the vertical direction, a buffer strip is respectively inserted in the slot, and when the door leaf is closed, the buffer strip is abutted against the second step part.

Buffering strip including locating the card portion of putting in the slot, with card portion of putting integrated into one piece's buffering portion, be equipped with at least one slot hole on the vertical direction in the buffering portion, when the door leaf closed, buffering portion supports and leans on in second ladder portion.

The slot is triangular.

The first step portion and the second step portion are three-level steps respectively, a door lock is arranged in the door leaf, and the free end of the door lock is telescopically arranged on the middle step of the three-level step in the first step portion in a penetrating mode.

By adopting the technical scheme, the beneficial effects of the utility model are that:

the first step part and the second step part of the utility model are arranged, so that the front surface of the door frame is flush with the front surface of the door leaf, the door body and the door frame are integrally formed when the door body is seen from the outside, and the door leaf, the door frame and the wall body are integrally formed to form an invisible door, so that the door body is more beautiful; in some places, the door body, the door frame and the wall body are required to be positioned indoors and outdoors and are all parallel and consistent, even if the wall body is thick, the thick door body can be adopted, so that the indoor and outdoor door frame is parallel and level with the door leaf, at the moment, the first step part and the second step part only need to adopt more steps, and the door leaf is prevented from being clamped in the door frame when being opened and closed; the first step part and the second step part are matched for use, wind enters the room from the gap and needs to change direction for multiple times through the step shape, the wind speed is reduced, less wind enters the room, and the wind blocking effect is achieved, so that the wind entering the room is less and gentler; furthermore, the buffer strip has a shock absorption function, buffers the collision between the door leaf and the door frame, and has a certain sealing function; furthermore, the free end of the door lock is telescopically arranged on the middle step of the third step on the first step part in a penetrating mode, and the door lock is prying-resistant and high in safety.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 5, the present embodiment provides a novel inward opening door, including a door frame 1, a door leaf 2 connected to the door frame 1 through hinges, wherein a front surface of the door leaf 2 faces outdoors, a back surface of the door leaf 2 faces indoors, an inner side of the door frame 1 is a stepped structure to form a first step portion 11, and the first step portion 11 protrudes inwards along an outdoor direction to form three steps; be equipped with the second step portion 21 that corresponds with first step portion 11 on the door leaf 2, second step portion 21 is located the handing-over department of door leaf 2 and door frame 1, and second step portion 21 is protruding to the outside along indoor direction and is formed three steps, and door frame 1 openly and door leaf 2 openly parallel and level. The first step portion 11 is provided with a slot 12 along the vertical direction, a buffer strip 3 is inserted into the slot 12, and when the door leaf 2 is closed, the buffer strip 3 is abutted against the second step portion 21. Buffering strip 3 is equipped with three slot hole 321 along being equipped with on the vertical direction in the buffering portion 32 including locating the card portion 31 in slot 12, with the buffering portion 32 of card portion 31 integrated into one piece, slot hole 321 is the triangle-shaped form, and when door leaf 2 closed, buffering portion 32 supported and leans on in second ladder portion 21, is equipped with lock 4 in the door leaf 2, and the middle part step of tertiary ladder is worn to locate on first ladder portion 11 telescopically to the free end of lock 4.

The number of the long holes 321 can be one, two, three or more, and specifically, the long holes 321 can be triangular, rectangular, circular or other shapes according to the setting condition, when the long holes 321 are triangular, the stability of the triangular shape is good, the upper portion of the long holes is easy to recover after being deformed by pressure, and deformation is not easy to occur.
