Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a double-step door leaf. Background Art

[0002] The door leaf is the main part of a door, typically made of wood, metal, plastic, or other materials, and is used to close or open the door opening. The door leaf is the core component of the door, attached to the door frame. It rotates, slides, or folds to open or close the door opening, thus controlling entry and exit.

[0003] The design and material selection of door panels depend on a variety of factors, including the intended use, safety requirements, aesthetics, durability, and cost. For example, in homes, doors are often made of wood or composite materials to provide an aesthetically pleasing and comfortable living environment; whereas in commercial or industrial spaces, doors may require greater safety and durability, and therefore may be made of metal or exotic alloys.

[0004] Doors can be opened in a variety of ways, including hinged doors, sliding doors, and folding doors. Hinged doors are the most common type of door, opening and closing by rotating the hinges. Sliding doors, on the other hand, open and close by sliding the door leaves, making them suitable for spaces with limited space or where space needs to be saved. Folding doors, on the other hand, can be opened and closed by folding multiple door leaves together, saving space and making them easier to open and close.

[0005] However, current door panels still have the following shortcomings: 1. Their overall noise reduction is poor, allowing external sounds to easily enter the room through the door panels; 2. Their overall strength is weak, making them easily pried open or damaged; 3. Their light transmittance is not obvious, allowing light from the outside environment to enter the room through the gap after the door is closed.

[0006] Therefore, it is necessary to design a double-step door leaf to solve the above-mentioned problems. Utility Model Content

[0013] As a preferred solution of the present invention, the third solid wood composite panel layer is a 5mm solid wood composite panel, and the interior of the filling layer is filled with graphene material.

[0014] As a preferred solution of the present invention, sealing strips are provided between the upper side of the inner top of the door leaf and the door frame, as well as between the protruding end above the outer top of the door leaf and the door frame.

[0015] As a preferred solution of the present invention, the thickness of the door leaf is 55MM.

[0016] As a preferred solution of the present invention, the thickness of the door cover is 40MM.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the present invention, an improved double-step door leaf is provided, so that the following effects can be achieved: 1.

[0031] For examples, see Figure 1-7 , the utility model provides a technical solution:

[0032] The double-step door leaf comprises a door leaf 1 and a door opening 7 for installing the door leaf 1. A door frame 2 is provided on the outside of the door leaf 1, and the door frame 2 is double-stepped. A door frame line 3 is provided on the outside of the door frame 2. A door hinge 4 is rotatably connected between the door leaf 1 and the door frame 2. The door hinge 4 adopts one of a parent-child hinge / three-dimensional hinge / casement hinge. A door lock hole 5 is provided inside the door leaf 1, and a door handle 6 is installed on the right side of the base surface of the door leaf 1 corresponding to the door lock hole 5.

[0033] Specifically, the interior of the door frame 2 is respectively provided with a first solid wood composite panel layer 21, a second solid wood composite panel layer 22, a door frame solid wood core board layer 23 and a door frame back board layer 24, and the first solid wood composite panel layer 21, the second solid wood composite panel layer 22, the door frame solid wood core board layer 23 and the door frame back board layer 24 are all bonded and connected with adhesives; the first solid wood composite panel layer 21 adopts a 12mm solid wood composite panel, and the second solid wood composite panel layer 22 adopts a 5mm solid wood composite panel; the thickness of the door leaf 1 is 55MM; the thickness of the door frame 2 is 40MM; the outside of the door leaf is also installed with a double frame keel, which can enhance the overall strength of the door leaf, making the door leaf more difficult to be pried open or damaged, thereby improving the overall strength of the double-step door leaf.

[0034] Specifically, the outer layers on both sides of the door leaf 1 are provided with a third solid wood composite panel layer 11, and a filling layer 12 is provided inside the third solid wood composite panel layer 11, and the outer edge of the door leaf 1 is also wrapped with an edge banding 13, which adopts PVC edge banding of the same color; the third solid wood composite panel layer 11 is a 5mm solid wood composite panel, and the interior of the filling layer 12 is filled with graphene material; since the door leaf is made of 5mm solid wood composite panel and the interior is flat and fully filled with graphene material, a quieter effect can be achieved.

[0035] Specifically, sealing strips 8 are provided between the inner top upper side of the door leaf 1 and the door frame 2, as well as between the protruding end of the outer top upper side of the door leaf 1 and the door frame 2; they effectively prevent external dust, water vapor, odor and other foreign substances from entering the room, and at the same time prevent light leakage.

[0036] The working process of the utility model is as follows: when using the double-step door leaf, first, a door opening 7 with a size of 2200*880MM in height and width needs to be pre-opened on the wall. During the opening process, it is necessary to ensure that the door opening 7 is vertical. Then, the door cover 2 is assembled. After the assembly is completed, it is adjusted between the door opening 7 to ensure that it matches the door opening 7. Then, the door cover 2 and the wall are fixed with the matching connectors. After that, the cutting position is marked on the door cover line with a marker and cut with a cutting machine. After cutting, the cut door cover line 3 is placed on the door for pre-installation. At the same time, it is checked whether the splicing between the door cover lines 3 is tight. Finally, the door cover line 3 is fixed with a glue gun / punching or steel nails. Finally, the door leaf 1 is installed through the door hinge 4.
