Description

Technical Field

[0001] This utility model relates to the field of door drawer technology, specifically a hollow handle door drawer and cabinet. Background Technology

[0002] "Door drawer" generally refers to the outer panel of a drawer that is pulled out. Currently, in both domestic and international markets, one-piece milled angled straight handle door drawers mainly employ the following two processes: such as... Figure 1 The single-sided oblique straight forming structure shown, and as... Figure 2 The four-sided beveled straight forming structure shown is as follows: the single-sided beveled straight forming structure only uses the beveled straight processing technology on one side of the door handle to form a single-sided beveled straight structure, while the four-sided beveled straight forming structure uses the beveled straight processing technology on all four edges of the door handle to form a single-sided beveled straight structure. However, the above single-sided or four-sided beveled straight forming structures have the problem of uneven force during use, and are only suitable for use in concealed scenarios where the handle is not visible. In addition, when multiple drawer surfaces are used side by side on the same horizontal plane, the required positioning accuracy of the single-sided or four-sided beveled straight forming structure is difficult to control, the processing yield is low, and the overall decorative effect is easily affected by the misalignment of the 45° beveled angle.

[0003] Therefore, there is an urgent need to develop an integrated door handle with a slanted, hollow design to overcome the aforementioned technical barriers. Utility Model Content

[0004] The purpose of this invention is to propose a hollow handle door drawer, which aims to solve the technical problem that existing door drawers are mostly one-piece milled inclined straight handle door drawers, which are difficult to process.

[0023] like Figures 3 to 7 As shown, a hollow door handle includes a core plate 1, with an inner plate 2 and an outer plate 3 respectively provided on the inner and outer sides of the core plate 1; The core board 1 includes a first board body 11 and a second board body 12. The first board body 11 is respectively provided on the left and right sides of the second board body 12 located in the middle. The height of the first board body 11 is equal to the height of the inner board 2 or the outer board 3. The total length of the first board body 11 and the two second board bodies 12 is equal to the length of the inner board 2 or the outer board 3. The height of the second plate 12 is less than the height of the first plate 11, and the top of the second plate 12 is inclined downward from the outside to the inside. The outer plate 3 is also provided with a notch 31 corresponding to the position of the second plate 12, so that the assembled core plate 1, inner plate 2 and outer plate 3 have a recessed handle groove 4.

[0024] This solution provides a novel non-integrated milled oblique straight handle door drawer—a hollow handle door drawer. It should be noted that the overall structure of the hollow handle door drawer in this solution is difficult to mill directly from a single piece, mainly because existing milling technology cannot mill an inwardly recessed oblique straight handle groove 4 in the middle of the plate.

[0025] Therefore, the hollow handle door drawer of this design is constructed from multiple panels, specifically including an inner panel 2, an outer panel 3, and a core panel 1. The core panel 1 consists of two first panels 11 and a middle second panel 12. The outer panel 3, serving as the outer panel of the door drawer, primarily provides aesthetic decoration, structural enclosure, and overall protection. The inner panel 2, serving as the inner panel of the door drawer, acts as both the mounting base for the core panel 1 and, together with the outer panel 3, forms the basic frame of the door drawer, ensuring overall structural strength. The first plate 11 on the left side of the core panel 1 is a supporting member on the left side of the door drawer, used to position the space on the left side of the door drawer, help maintain the stability of the frame, and provide lateral support for the internal structure; the first plate 11 on the right side is a supporting member on the right side, and the two first plates 11 together realize the symmetrical division of the internal space of the door drawer and the reinforcement of the frame; the second plate 12 is mainly a supporting member in the middle of the door drawer, and its top has a beveled surface. The outer plate 3 has a notch 31 at the corresponding position. The top of the second plate 12 is not higher than the notch 31, making it easier for the user's fingers to position when pulling the handle groove 4.

[0026] The structure formed by the inner panel 2, outer panel 3, and core panel 1 adopts an integrated handle-free design, breaking through the limitations of traditional single-sided / four-sided oblique straight process. It has a hollow oblique straight handle groove 4 in the middle of the door drawer, which improves the overall integrity and aesthetics of the door panel, solves the problem of uneven force during use, and enhances the service life of the track. At the same time, it reduces the high precision requirements of oblique straight cutting, reduces processing difficulty and cost, improves yield, and solves the problem that round cutter shaft milling cannot form a hollow integrated structure, filling the gap in the integrated hollow oblique straight handle structure.

[0027] Furthermore, on the side projection plane, the angle α between the inclined surface of the top of the second plate 12 and the inner plate 2 is between 30-50°. For example... Figure 7 As shown, the included angle α can be adjusted from 30-50° as needed, with the preferred angle being 45°, which is more ergonomic. The angled cut naturally guides the fingers to apply force, reducing the feeling of constraint during operation and making it easier to open and close with one hand.

[0028] Furthermore, an arc-shaped groove 121 is also provided in the middle of the top end of the second plate 12. For example... Figure 5 As shown, the core board 1 of this design is approximately 18mm thick. A circular arc-shaped groove 121 is provided on the beveled surface at the top of the core board 1. This groove 121 not only increases the contact area for fingers but also provides additional friction through tiny wave-like undulations within it, making pushing and pulling operations more effortless and non-slip. Simultaneously, the circular arc-shaped groove 121 guides the fingers to natural positioning, improving operational accuracy. Furthermore, the circular arc-shaped groove 121 also considers safety and comfort, making it particularly suitable for frequently used applications such as drawers and cabinet doors.

[0029] Furthermore, the diameter of the arc-shaped groove 121 is 2-3 mm, and the depth is 1-2 mm. The arc-shaped groove 121 is mainly designed to facilitate the user's better gripping of the inside of the handle groove 4. Its diameter is set to 2-3 mm, which is more in line with the size of the user's fingers; the depth can be adaptively adjusted within the range of 1-2 mm.

[0030] Furthermore, the second plate 12 and the first plates 11 on both sides are detachably connected by fixing rods 13. The connection between the first plate 11 and the second plates 12 on both sides via fixing rods 13 ensures accurate alignment between the first plate 11 and the second plate 12, helps to separate the internal space of the door drawer, and avoids assembly misalignment; it also further enhances the longitudinal stability of the frame. The fixing rods 13 can actually be made of wooden tenons, eliminating the need for metal parts, preserving the natural characteristics of wood, and simplifying the processing procedure.

[0031] Furthermore, the second plate 12 and the first plates 11 on both sides are connected by at least three spaced-apart fixing rods 13, which are cylindrical. In this embodiment, at least three fixing rods 13 (i.e., wooden dovetails) are used to fix the first plate 11 and the second plate 12. The three fixing rods 13 can distribute the force and improve tensile and shear resistance. Compared with a single fixing rod 13, the above connection structure is more impact-resistant and less prone to loosening.

[0032] Of course, in other embodiments, the fixing rod 13 can also be adjusted to two or four rods, etc., and can be added or removed as needed according to different sizes or fixing requirements.

[0033] Furthermore, the core board 1 is glued and fixed to the inner board 2 and the outer board 3. In this embodiment, glue is uniformly applied to the inner surface of the inner board 2 and the inner surface of the outer board 3 on one side. The first board 11 is placed on the left side of the outer board 3, the second board 11 is placed on the right side of the outer board 3, and the first board 11 is placed in the middle of the two first boards 11. After ensuring that the three are aligned according to the preset size, the core board 1 and the outer board 3 are penetrated by a nail to achieve the initial fixation of the core board 1. Then, the inner board 2 coated with glue is covered on the other side of the fixed core board 1, so that the inner board 2, the core board 1 and the outer board 3 form a "sandwich" layered structure. Then, the whole is pressed together to ensure that the glue layer is fully adhered. After the glue layer is completely cured and dried, the four sides of the hollow handle door drawer are precisely cut to ensure dimensional accuracy, and the sides after precision cutting are sealed.

[0034] In the above structure, the core board 1, inner board 2 and outer board 3 are fixed by adhesive. The adhesive is evenly distributed on each joint surface, reducing gaps and deformation risks; avoiding holes caused by traditional screws, maintaining the flatness and beauty of the product surface; and the adhesive layer can also enhance the integrity between the core board 1, inner board 2 and outer board 3, and improve impact resistance and durability.

[0035] Furthermore, the inner panel 2 and / or the outer panel 3 are also covered with a wood veneer layer. The core board 1, inner panel 2, and outer panel 3 of this solution can be made of solid wood or composite wood boards. A wood veneer process can also be applied to the inner panel 2 and outer panel 3 to complete the surface treatment, which can provide the outer panel 3 / inner panel 2 with richer wood texture and feel, thereby improving the appearance of the furniture (cabinet). Then, according to the size requirements of the door drawers, the outer panel 3 / inner panel 2 are cut and milled to produce compliant panels for later use.

[0036] The first panel 11 is made of raw board substrate, cut and processed according to the design dimensions, and then all sides are sealed to prevent the substrate from getting damp and improve the edge flatness, for later use; the second panel 12 is also made of raw board substrate, cut and processed into basic specifications, and then cut diagonally to form the above-mentioned specific inclined assembly angle / fitting surface, and finally the diagonal cut surface is sealed, for later use.

[0037] Furthermore, the surface of the outer panel 3 is also provided with a paint layer. After the inner panel 2 and the outer panel 3 are treated as described above, a paint layer can be applied to the surface of the outer panel 3 through an overall painting process. This can prevent the wooden outer panel 3 from oxidizing, rusting, or being corroded by moisture; it also provides the outer panel 3 with a wider range of colors and glosses, improving the product's appearance quality; in addition, the surface of the outer panel 3 is also smoother, reducing stain adhesion and facilitating subsequent cleaning.

[0038] Of course, in other embodiments, a paint layer may be provided on the inner surface of the inner label plate if necessary.

[0039] Specifically, this utility model also proposes a cabinet body, wherein the outer side of the cabinet body is detachably equipped with the aforementioned hollow handle drawer. For example... Figure 8 As shown, the cabinet is equipped with any of the above-mentioned hollow handle door drawers, and therefore has the same beneficial effects as the above-mentioned hollow handle door drawers, which will not be described in detail here.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
