[0033] The following will provide a clear and complete description of the technical solutions in the present embodiment of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only preferred embodiments of the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See attached Figures 1 to 6 In the embodiment of the utility model, a door panel molding buckle line includes a buckle line body 10, the buckle line body 10 includes a filling plate and a coating layer 12 wrapped around the outer periphery of the filling plate, the coating layer 12 is formed by laminating a decorative paper and a printed body; in this embodiment, the decorative paper is preferably melamine paper (also called melamine impregnated paper / melamine impregnated paper), of course, the decorative paper can also be PVC film, PET film, PETG film, PP film, veneer and other materials; the filling plate is usually a medium-density fiberboard (made of wood fiber), of course, it can also be a solid wood board (natural wood material), density board (plywood lamination), composite board (solid wood material and wood fiber combination), steel plate and other materials. The printed body is at least one of non-woven fabric, plain paper, non-woven paper, and printed paper; in this embodiment, the printed body is preferably non-woven fabric, and the non-woven fabric is usually printed with wood grain or wood color, so as to be used to make a wooden door with a solid wood appearance. The coating layer 12 is usually coated on the periphery of the medium fiberboard 11 by glue. The lamination process of the melamine paper and the non-woven fabric can be found in existing documents such as Chinese patent publication CN214491990U and CN113584934A.

[0037] In this way, the medium density fiberboard 11 is fully covered by pressing melamine paper and printed body (preferably non-woven fabric) as the coating layer 12 of the buckle line body 10, thereby better improving the moisture-proof and deformation-resistant capabilities of the medium density fiberboard 11 and improving the structural stability of the shaped buckle line; at the same time, the shaped buckle line of corresponding length can be quickly cut according to customer requirements for installation with the door panel, which has the advantages of short production cycle and fast response to market demand; and it also has the advantages of low manufacturing difficulty, environmentally friendly process, and low requirements on workers' business capabilities.

[0038] In actual application, the buckle line body 10 is extended with a decorative curved surface 101, and the decorative curved surface 101 is usually convex forward, so as to improve the appearance of the product and reduce the hiding of dust. Compared with the edge surface, the decorative curved surface 101 also has the advantages of preventing bumps and having higher safety performance. Of course, under some different requirements, the decorative curved surface 101 can also be a concave arc groove. Of course, the buckle line body 10 can also be other special-shaped structures.

[0039] This embodiment also discloses a door panel, including a door panel body 20, and the door panel body 20 is installed with the above-mentioned door panel molding buckle line. Preferably, the door panel body 20 includes a front trim panel 21, a front panel 22, a core panel 23, a rear panel 24, and a rear trim panel 25 arranged in sequence from front to back; the core panel 23 is made of medium-density fiberboard 11; or, the core panel 23 is formed by solid wood filling. The front panel 22 and the rear panel 24 are made of metal plates or plastic plates; the front trim panel 21 and the rear trim panel 25 are made of melamine paper. In this way, through the specific setting of the door panel body 20, when the core board 23 is made of medium-density fiberboard 11 or solid wood filling, the front panel 22 and the rear panel 24 can effectively prevent the deformation of the core board 23 and improve the stability of the core board 23 structure; at the same time, the use of melamine paper as the front decorative panel 21 and the rear decorative panel 25 can simplify the production process of the door panel and ensure the quality of the door panel (most traditional wooden doors use paint spraying technology to process the surface of the door panel. The shortcomings of using the spraying technology are: 1. It is not environmentally friendly and poses a great hidden danger to the health of the operators; 2. The paint surface is easy to crack and the paint is easy to fall off due to bumps; 3. It requires high skills from the workers, otherwise it is easy to have uneven paint thickness and strong granularity of the paint surface; and the door panel of the present application uses melamine paper to decorate the surface of the door panel, which solves the shortcomings of traditional painted doors).

[0040] The buckle wire body 10 has a first buckle 102 for installation with the door panel body 20, and the door panel body 20 has a second buckle 201 adapted to the first buckle 102; generally, the first buckle 102 is a buckle convex, and the second buckle 201 is a buckle slot; during installation, part of the buckle wire body 10 is located in the door panel body 20, further improving the assembly stability of the buckle wire body 10. The second buckle 201 (slot) is preferably provided on the front trim 21 and the rear trim 25, so as to ensure the assembly stability of the buckle wire body 10 without damaging the stability of the structure of the door panel body 20 itself.

[0041] The design focus of the utility model is that it mainly designs the molding buckle line structure (adopting a fully covered structure), the door panel structure and the installation structure of the two, which has the following advantages:

[0042] 1. Compared with installing the molding buckle line on the door panel before painting (such as painting wooden doors), it has the advantages of lower cost, scratch resistance, no paint loss, and environmentally friendly processing technology;

[0043] Second, compared with wooden doors with PVC coating, the door panel structure of the present application does not have the problems of fading, easy degumming, and easy scratching;

[0044] 3. Compared with paint-free polished wooden doors, the molding buckle line and door panels of this application are convenient for customers to have special sizes, so that manufacturers can produce quickly, shorten the production cycle, and respond quickly to market demand;

[0045] 4. Compared with directly installing the molding buckle line on the door panel and then covering the entire door panel with melamine paper, it provides better covering protection for the molding buckle line, has higher degree of freedom in DIY design, improves the moisture-proof and deformation-resistant ability of the molding buckle line, and improves the structural stability of the medium-density fiberboard of the molding buckle line.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention.
