Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-deformation and anti-cracking door panels, and particularly relates to an anti-deformation and anti-cracking door panel. BACKGROUND

[0002] In the field of furniture manufacturing and architectural decoration, door panels are widely used. With the improvement of people's living quality, the quality and durability of door panels are increasingly required. High-quality door panels not only improve the overall aesthetics of the space, but also bring convenience and comfort to people's lives. The design and manufacturing technology of door panels have been continuously developed from the initial simple structure to today's diversified design, and have made significant progress in functionality and decoration.

[0003] In traditional door panel manufacturing, in order to achieve the connection of the door core panel and the frame, a direct splicing method is often used, that is, the cut door core panel is directly embedded into the frame composed of door edges and cross bars, and then glued or nailed with nails for fixing. For the door edges and cross bars, a single material is generally used to make an integral structure, without internal subdivision design. When connecting the components, a simple physical connection method is usually used, and there is a lack of special design to enhance the stability and adaptability of the connection.

[0004] In view of the related art, the direct splicing and simple fixing method makes the door panel prone to deformation and cracking when affected by environmental factors such as temperature and humidity changes. The knife edge generated during the cutting process in the door panel manufacturing process causes the internal moisture to evaporate, which easily leads to deformation and cracking. The wooden door edge and cross bar structure lack sufficient stability and adaptability, and cannot effectively buffer the stress changes inside the door panel, so that the door panel cannot effectively disperse and release when facing stress in different directions, thereby further increasing the risk of deformation and cracking.

DETAILED DESCRIPTION

[0035] The application will be further described in detail below with reference to all the accompanying drawings.

[0036] The embodiment of the application discloses a deformation and cracking prevention door plate.

[0037] With reference to Figure 1 A deformation and cracking prevention door plate comprises a door core plate 1, two vertical edges 2 and two horizontal stops 3, wherein the door core plate 1 is fixedly connected between the two vertical edges 2 and the two horizontal stops 3, the vertical edges 2 and the horizontal stops 3 are fixedly connected in sequence and in head-tail mode along the circumference of the door core plate 1, and the horizontal stop 3 is fixed between the two vertical edges 2, so that a complete door plate frame is formed, and the stability of the door plate as a whole is enhanced.

[0038] With reference to Figure 2, the vertical edge 2 includes a vertical inner core 21, two door edge plugs 22 and two outer side plates 23, the door core plate 1, the vertical inner core 21 and the two door edge plugs 22 are located between the two outer side plates 23 in the horizontal direction, the vertical inner core 21 and the two door edge plugs 22 are fixedly connected with the outer side plates 23, and the two door edge plugs 22 are respectively fixedly connected at two ends of the vertical inner core 21 in the vertical direction. The vertical inner core 21 can generally be made of wood materials such as oak, fir and the like, and has certain strength and toughness, and some new composite materials can also be used to improve the stability. The wood grain direction of the vertical inner core 21 extends in the vertical direction, and the wood grain direction of the vertical inner core 21 is perpendicular to the wood grain direction of the door edge plug 22. The setting of the wood grain direction is helpful to disperse the stress received by the door plate. When the door plate receives forces in different directions, the perpendicular wood grain direction can disperse the stress in different directions, reducing the risk of deformation and cracking caused by stress concentration. The door edge plug 22 is usually also made of wood, and the material thereof can be the same as or similar to that of the vertical inner core 21, the shape of the door edge plug 22 is rectangular block, and the door edge plug 22 is fixedly connected with the vertical inner core 21 through glue or mortise and tenon structure. The outer side plate 23 can be made of a wood plate with relatively hard texture, such as high-density fiberboard, and has a smooth surface, which can protect the internal structure and be aesthetic. The outer side plate 23 is attached to the two sides of the vertical inner core 21 and the door edge plug 22 through glue, and is tightly combined with the vertical inner core 21 and the door edge plug 22 to form an integral vertical edge 2 structure.

[0039] With reference to Figure 2 The vertical edge 2 further includes an inner edge plate 24 and an outer edge plate 25, the inner edge plate 24 is fixedly arranged at one end of the vertical inner core 21 close to the door core plate 1, the outer edge plate 25 is fixedly arranged at one end of the vertical inner core 21 away from the door core plate 1, the door edge plug 22 is fixedly arranged between the inner edge plate 24 and the outer edge plate 25, and the inner edge plate 24 and the outer edge plate 25 are fixedly arranged between the two outer side plates 23. The inner edge plate 24 and the outer edge plate 25 can be made of the same or similar material as the outer side plate 23, and are fixedly connected with the vertical inner core 21, the outer side plate 23 and the door edge plug 22 through glue or mortise and tenon structure to form a closed vertical edge 2 structure, further enhancing the stability of the vertical edge 2. The inner edge plate 24 is used to connect with the door core plate 1, one of the outer edge plates 25 is used to install a door lock, and the other outer edge plate 25 is used to install a hinge.

[0040] With reference to Figure 2The end face of the vertical inner core 21 and the outer side plate 23 is sequentially provided with a plurality of cutting grooves 211 in the vertical direction. The cutting grooves 211 penetrate the vertical inner core 21 in the horizontal direction, the depth of the cutting grooves 211 is not greater than half of the distance between the two outer side plates 23, and the cutting grooves 211 located on different sides are arranged in the vertical direction. The design of the cutting grooves 211 can further enhance the dispersion and release capacity of the door panel to stress. When the door panel generates stress due to environmental factors, the cutting grooves 211 can serve as a stress buffer area, so that the stress is released at the cutting grooves 211, avoiding stress concentration at a certain point and causing the door panel to deform or crack. The shape of the cutting grooves 211 is rectangular, and the processing can be carried out by professional woodworking tools.

[0041] Referring to Figure 2 and 3 , one end of the vertical edge 2 close to the horizontal bar 3 is provided with a first connecting assembly 4, and the first connecting assembly 4 is used for connecting the vertical edge 2 and the horizontal bar 3, and the vertical edge 2 and the door core plate 1. The first connecting assembly 4 includes a first vertical plug strip 41 and a plurality of plug rods 42 arranged in the vertical direction.
