Description

Technical Field

[0001] The utility model relates to the technical field of furniture structures, in particular to a three-side clamped buckle cabinet door structure. Background Art

[0002] Buckle molding, also known as door face molding, is a crucial component of doors, primarily used on the exterior. By varying its material, size, and shape, the door's aesthetic can be enhanced with a more three-dimensional and elegant aesthetic. Common doors are made of wood, and the chemical component lignin in wood strongly absorbs UV rays. The subtle irregularities of wood's surface structure scatter light. When combined with buckle molding, this not only enhances the door's visual appeal but also effectively reduces eye fatigue and damage caused by direct sunlight.

[0003] To accommodate transportation needs, some current buckle-line door products are designed as multiple loose components that are assembled after delivery to the customer's end-user. Sometimes, the customer must assemble the components themselves to complete the buckle-line door product. Conventional assembly methods require the customer to first press the buckle line against the door frame / frame, then secure the connection using nails. However, nailing makes it difficult to ensure the surface smoothness of the final product and leaves nail holes, which not only detracts from the aesthetics of the original wood cabinet door but also makes it difficult to achieve a harmonious color and style. Worse still, nails can cause cracks or deformation in the wood. Furthermore, this fixing method increases customer complexity and incurs additional nail material costs. While some manufacturers pre-cut slots or holes in the components, allowing the customer to simply align the assembly parts with these slots or holes and apply adhesive, relying solely on adhesive fixings also presents risks: glue can lose its viscosity over time, leading to structural cracking or even detachment. Summary of the Invention

[0004] In response to the problems in the related technology, the utility model proposes a three-sided snap-on cabinet door structure, which is convenient for users to assemble snap-on products, has low assembly difficulty, and does not affect the aesthetic effect and fixing effect after assembly.

[0005] The utility model is achieved in this way:

[0006] A three-side clamped buckle cabinet door structure comprises a door frame, a door core and a buckle, wherein the buckle is protruding on the front of the door frame; the door frame is a rectangular frame, the door core is a rectangular core board, and the buckle is a rectangular frame; a first connecting portion is provided along three sides of the inner side of the door frame; on both sides of the first connecting portion, a raised limiting portion is provided on the side close to the back, and a concave first wire groove is provided on the side close to the front; a raised second connecting portion is provided on the side close to the front of the first wire groove;

[0007] The outer edge of the door core is stepped, and the cross section of the door core is formed into a convex structure, including a wide portion and a narrow portion; the narrow portion faces the back, and the wide portion is connected to the first connecting portion and abuts against the limiting portion;

[0008] A second concave wire groove is provided along three sides of the outer side of the buckle line; the second wire groove has a first convex portion and a second convex portion on both sides; the first convex portion is cooperatively connected with the first wire groove; the second wire groove is cooperatively connected with the second connecting portion; the side of the buckle line facing the back is tightly fitted with the door frame and the door core at the same time; the second convex portion is exposed on the front side;

[0009] The buckle line is a split assembly structure, including four segments; the front projections of the segments are all trapezoidal; two segments are vertically connected to each other through an inclined surface; three of the segments have the second wire groove and the corresponding first and second protrusions on the inner side, and one segment has only the second protrusion on the inner surface, and the rest is a plane.

[0010] Furthermore, the door frame, the door core, and the buckle line are coated with glue on the connected parts or all surfaces thereof, and the glue is epoxy resin AB glue, polyurethane wood glue, plywood glue, or yellow glue.

[0011] From the front to the back of the door frame, the second connecting portion, the first wire groove, the first connecting portion, and the stopper are sequentially arranged, all extending along the inner edge of the door frame. The door frame, door core, and buckle wire are tightly interlocked. The stopper clamps the door core between the door frame and the buckle wire, while the buckle wire snaps directly into the second connecting portion. Ultimately, these three components are securely connected without nailing, resulting in a cabinet door that maintains both aesthetics and stability.

[0012] During installation, first install the door core within the door frame, then the buckle wire. The segment with the second wire groove is first interlocked and connected, followed by the segment with a flat inner surface. The final segment is then clipped between the other three segments and the door frame. This ensures sufficient support and compressive strength for a secure connection. Glue can be used to further strengthen the connection between the door frame, door core, and buckle wire.

[0013] As a further optimization of the above solution, on both sides of the first wire trough, the protrusion of the second connecting portion is shorter than the protrusion of the first connecting portion. This maximizes the contact area between the buckle wire and the door frame, and ensures a more stable connection by ensuring the contact area between the buckle wire, the door frame, and the door core is as uniform as possible.

[0014] As a further optimization of the above solution, the door core and the limiting portion are connected by a smooth transition on the back side; the door core and the first connecting portion are connected by a smooth transition on the front side.

[0015] As a further optimization of the above solution, the length of the first convex portion is smaller than the length of the second convex portion.

[0016] As a further optimization of the above solution, the door frame is formed in one piece;

[0017] Or the door frame is a split assembly structure, including four frames; the frames are all rectangular long strip structures; or the frames are all trapezoidal long strip structures, and two frames are vertically connected to each other through an inclined surface.

[0018] As a further optimization of the above solution, only one of the segments whose inner surface is a plane is coated with glue at the connection.

[0019] As a further optimization of the above solution, the door frame, the door core and the buckle line are all made of solid wood.

[0020] The beneficial effects are as follows:

[0021] This utility model provides a three-sided, clip-on cabinet door structure, in which the door frame, door core, and clip-on cable are tightly interlocked. A retaining member and two cable ducts clamp the door core between the door frame and the clip-on cable, while the clip-on cable is directly clipped into the second connecting portion. Ultimately, the three components are securely connected without the need for nails, resulting in a cabinet door that maintains both aesthetics and stability, is easy to assemble, and is convenient to transport.
