Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wooden furniture manufacturing technology, specifically relating to a paint-resistant bending cabinet door. Background Technology
[0002] Solid wood cabinet doors, as a crucial component in the furniture industry, directly impact the lifespan and aesthetics of furniture due to their structural stability and surface durability. Traditional solid wood cabinet doors face two major technical bottlenecks during long-term use: First, the inherent anisotropy of solid wood makes the door frame susceptible to bending and deformation caused by humidity changes and external forces, especially when the cabinet door is large, where lateral stress-induced deformation is more pronounced. Second, the assembly method between the door panel and the frame, as well as insufficient paint adhesion, leads to cracking and peeling of the paint layer due to wood deformation, affecting both protective performance and increasing maintenance costs. Utility Model Content
[0003] To address the problem of insufficient bending resistance in existing solid wood cabinet doors, which easily leads to structural deformation, a paint-resistant bending cabinet door is proposed. This utility model provides the following technical solution:
[0004] A paint-resistant bending cabinet door includes a solid wood frame and a door core panel. The solid wood frame has filling holes in which metal blocks are embedded. The solid wood frame has mounting holes running through it from front to back. A front baffle is fixedly connected to the front side of the solid wood frame. The front baffle extends into the mounting holes to form a front baffle section. The inner wall of the mounting holes has mounting grooves in which a rear baffle strip is inserted. The door core panel is placed in the mounting holes and its front and rear sides are respectively attached to the front baffle section and the rear baffle strip.
[0005] Preferably, the filling hole is rectangular, and the metal block is connected to the filling hole.
[0006] Preferably, the filling hole is set perpendicular to the front side wall of the solid wood frame.
[0007] Preferably, the door core panel includes a central part, a transition part, and a plug-in part from the inside out. The front side of the transition part is an arc surface, and the rear side of the transition part is flush with the rear side of the central part. Both the plug-in part and the central part are straight plates, and the thickness of the plug-in part is less than that of the central part.
[0008] Preferably, the door panel and the solid wood frame are fitted with a clearance.
[0009] Preferably, the front bumper extends forward to form a protective protrusion, and the front side of the protective protrusion is a convex arc surface.
[0010] Preferably, the rear guard strip includes an embedding part and a limiting part. The cross-section of the embedding part and the mounting groove is square, and the cross-section of the limiting part is a right-angled triangle with an arc-shaped hypotenuse. The door panel is attached to the right-angled side of the limiting part.
[0011] Preferably, the limiting portion extends rearward to the rear side of the mounting groove.
[0012] Preferably, the thickness of the metal block in the front-to-back direction accounts for 60%-75% of the thickness of the solid wood frame.
[0013] Preferably, the solid wood frame includes horizontal and vertical panels, which are joined together to form a frame shape. The vertical panels are made of single veneers spliced together to form a complete filling hole.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Embedding metal blocks inside the solid wood frame can effectively enhance the overall bending resistance of the cabinet door. When the cabinet door is subjected to lateral force when it is opened and closed, the metal blocks act as load-bearing components to disperse stress, greatly reducing the risk of bending deformation.
[0016] 2. The gap between the door core panel and the solid wood frame is designed to compensate for the seasonal expansion and contraction of the wood. The front and rear sides are respectively attached to the front and rear baffles. After assembly, the door core panel is uniformly painted to ensure that it is securely fixed and effectively reduce the risk of paint cracking during long-term use.
[0017] 3. The rear guard strip, through the arc-shaped part of its limiting section, forms a guiding effect when the door core panel is inserted, so there is no need for precise alignment during the installation process. At the same time, the arc-shaped surface forms an elastic pre-tightening force with the door core panel, eliminating vibration and abnormal noise that may occur after long-term use.

Detailed Implementation
[0026] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.
[0027] Example 1
[0028] like Figure 1-5 As shown, a paint-resistant bending cabinet door includes a solid wood frame 1 and a door core panel 3. The solid wood frame 1 has filling holes, and metal blocks 4 are embedded in the filling holes. By embedding metal blocks 4, the overall bending resistance of the door frame can be improved. The solid wood frame 1 has a through-hole 101. In this embodiment, the solid wood frame 1 surrounds to form a mounting hole 101. A front baffle 2 is fixedly connected to the front side of the solid wood frame 1. The front baffle 2 extends into the mounting hole 101 to form a front baffle. The inner wall of the mounting hole 101 is provided with a mounting groove 102. A rear baffle 5 is inserted into the mounting groove 102. The door core panel 3 is placed in the mounting hole 101 and its front and rear sides are respectively bonded to the front baffle and the rear baffle 5. After assembly, it is uniformly painted to ensure that the door core panel 3 is reliably fixed and effectively reduce the risk of paint cracking during long-term use.
[0029] Specifically, the filling hole is rectangular and is set perpendicular to the outer wall of the solid wood frame 1. When the cabinet door is opened and closed and subjected to lateral force, the metal block 4 can be instantly transformed into the main load-bearing component to effectively resist bending deformation.
[0030] Specifically, the solid wood frame 1 includes vertical panels 11 and horizontal panels 12. The horizontal panels 12 and vertical panels 11 are joined together to form a frame. The vertical panels 11 are made of two veneers of different specifications. The joints of the two veneers are provided with semi-grooves. The two semi-grooves are joined together to form a complete filling hole, so that during installation, the metal block 4 can be placed and glued into one of the semi-grooves, and then the other veneer can be joined. This allows the metal block 4 to be installed quickly, reducing the processing difficulty.
[0031] Specifically, the door core panel 3 includes a central part 31, a transition part 32 and a plug-in part 33 from the inside to the outside. The front side of the transition part 32 is curved, and the rear side of the transition part 32 is flush with the rear side of the central part 31. Both the plug-in part 33 and the central part 31 are straight, and the thickness of the plug-in part 33 is less than that of the central part 31.
[0032] Specifically, the door core panel 3 and the solid wood frame 1 are fitted with a gap to compensate for the seasonal expansion and contraction of the wood and to avoid the installation stress caused by the interference fit. At the same time, it provides a uniform penetration channel for the paint coating and enhances the bonding force of the interface.
[0033] Specifically, the front baffle 2 extends forward to form a protective protrusion 21. The front side of the protective protrusion 21 is a convex arc surface, which can better absorb impact and improve the protection of the door panel 3.
[0034] Specifically, the rear retaining strip 5 includes an insert portion 51 and a limiting portion 52. The cross-sections of the insert portion 51 and the mounting groove 102 are both square, while the cross-section of the limiting portion 52 is a right-angled triangle with an arc-shaped hypotenuse, which provides a guiding effect when the door panel 3 is inserted. The installation process does not require precise alignment. At the same time, the arc-shaped surface forms an elastic preload with the door panel 3, eliminating vibration and noise that may occur during long-term use. The door panel 3 fits against the plane where the right-angled side of the limiting portion 52 is located, forming a stable surface contact.
[0035] Specifically, the limiting part 52 extends rearward to the rear side of the mounting groove 102, and its extended part fits tightly with the solid wood frame 1, blocking the moisture penetration path along the joint and extending the service life of the door panel.
[0036] Specifically, the thickness of the metal block 4 in the front-to-back direction accounts for 60%-75% of the thickness of the solid wood frame 1. Specifically, in this embodiment, the thickness of the solid wood frame 1 is 22mm, the thickness of the metal block 4 in the front-to-back direction is 15mm, and the width of the vertical plate 11 is 65mm. The gap at the connection between the front and back sides of the door core panel 3 in the figure is for easy differentiation of the structure. In actual production, there is a glue layer in the gap, and the parts are tightly connected by the glue layer.
[0037] Example 2
[0038] like Figure 6 and Figure 7 As shown, in this embodiment, the solid wood frame 1 encloses two mounting holes 101, one above the other. Door panels 3 are installed in both mounting holes 101. The two mounting holes 101 are separated by a horizontal baffle 13. Mounting grooves 102 are arranged on both the upper and lower sides of the horizontal baffle 13. The two door panels 3 are fixed by the front baffle 2 and the rear baffle 5. The heights of the two mounting holes 101 can be different, and similarly, the heights of the two door panels 3 can also be different. Following the same connection method, structures with three mounting holes 101, four mounting holes 101, and even more mounting holes 101 can be extended. The connection structure has been described in detail in Embodiment 1 and will not be repeated here.
