Description

Technical Field

[0001] The utility model relates to the technical field of cabinet structures, and particularly discloses a cabinet structure with a top and bottom hinge reinforcement shell. Background Art

[0002] A top-bottom hinge is a connector widely used in furniture hardware accessories such as cabinets and doors. It allows doors or cabinets to be opened and closed in a vertical plane through hinge points at the upper and lower ends. This hinge design can withstand heavy weight and provide smooth opening and closing movements. In furniture design, the use of top-bottom hinges greatly improves the service life of furniture and the user experience.

[0003] Currently, the most common method for installing hinges on the market involves directly slotting the wood panel and then installing the hinge into the slot. Because the hinge body is riveted together using only a few nails, the weight of the door leaf can easily cause the hinge to loosen and the door leaf to sag during installation. In severe cases, the wood panel can even crack, which not only affects the quality and service life of the cabinet but also negatively impacts the user experience.

[0004] In response to the deficiencies in the existing technology, some patents have proposed improvement plans. For example, patent CN202322156095 - a cabinet structure with a top and bottom hinge, which achieves reinforcement protection for the top and bottom hinges by setting a hinge box. However, this patent solution has some shortcomings. First, the hinge box is connected to the plate body with screws on its side, and the screw connection concentrates a large stress on the plate body. This connection method is not only not conducive to the connection stability of the hinge box, but also not conducive to maintaining the structural strength of the plate body; secondly, the solution requires an aluminum beam to be set on the outside to shield the hinge box, which results in inconsistency between the surface appearance of the plate body and the aluminum beam, affecting the overall aesthetics of the cabinet body.

[0005] In addition, patent CN202221257692 - a hidden top and bottom hinge for a stainless steel cabinet. Although the hinge embedded seat provided therein can also achieve the reinforcement and protection of the top and bottom hinges, it also has some disadvantages. The installation scheme of this patent is to fix the hinge embedded seat to the wooden board outer box with screws before the wooden board inner box and the wooden board outer box are pressed into shape. Such a structural design is only suitable for cabinets made of metal plates such as stainless steel. Since the standard thickness of wooden boards is generally at least 18mm, if the structure of this patent is adopted, the board body of the built-in hinge embedded seat will be too thick, thereby increasing the weight and cost of the cabinet. Therefore, the structure of this patent has application limitations and is not suitable for all types of cabinet materials.

[0006] In summary, the existing installation methods of top and bottom hinges and existing patent solutions have certain limitations and shortcomings, and require further improvement and innovation to meet the market's higher requirements for cabinet structure stability and aesthetics.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] This embodiment discloses a cabinet structure with a top and bottom hinge reinforcement shell, referring to Figure 1-4 , which includes a wooden board 1, a rigid reinforcement shell 2, fasteners and a top and bottom hinge 3.

[0033] Among them, the wooden board 1 is a component of the cabinet structure and can be a top plate or a bottom plate. Its front end surface is hollowed out along the direction in which the top and bottom hinges 3 are installed to form a mounting groove 11; the rigid reinforcement shell 2 is profiled and embedded in the mounting groove 11, and it is provided with a accommodating cavity 21 with an opening at the front end; at least one fastener is provided, which locks and fixes the rigid reinforcement shell 2 to the mounting groove 11 along the direction in which the top and bottom hinges 3 are installed. Specifically, the fastener can be a screw. The fastener of this embodiment includes a first fastener, referring to Figure 3 A first mounting hole 211 is provided on the side wall of the accommodating cavity 21 of the rigid reinforcement shell 2 facing the opening direction, and the first fastener passes through the first mounting hole 211 and is connected to the bottom wall of the mounting groove 11 of the wooden board 1. In this embodiment, two groups of first mounting holes 211 and corresponding first fasteners can be provided (three groups of first mounting holes 211 and corresponding first fasteners of the heavy-duty top and bottom hinges can be provided); the top and bottom hinge 3 is accommodated in the accommodating cavity 21 of the rigid reinforcement shell 2 and remains relatively fixed, with its front end exposed at the opening of the accommodating cavity 21 for use in connecting the door leaf.

[0034] This solution opens an installation groove 11 on the front end face of the wooden board 1 and sets a rigid reinforcement shell 2 in the installation groove 11. The rigid reinforcement shell 2 is used to fully protect the top and bottom hinges 3 so that it can be installed on the wooden board 1. Compared with the traditional cabinet structure in which the top and bottom hinges are directly riveted to the wooden board, the wooden board 1 of this solution is subjected to less concentrated stress. When the weight of the door leaf is applied to the top and bottom hinges 3, the rigid reinforcement shell 2 can disperse the force, thereby providing sufficient support and protection for the top and bottom hinges 3, and better avoiding problems such as the top and bottom hinges 3 loosening on the wooden board 1, the door leaf sagging or the wooden board bursting. Moreover, the rigid reinforcement shell 2 of this solution is concealedly embedded in the wooden board 1, which makes the overall aesthetics of the cabinet structure better, does not require additional beams to cover it, and also reduces the cost.

[0035] Reference Figure 2-3The fasteners of this embodiment also include a second fastener. A positioning piece 22 is integrally formed on the side of the opening of the accommodating cavity 21 of the rigid reinforcement shell 2. A positioning groove 12 is provided on the front surface of the wooden board 1 for the positioning piece 22 to be inserted into. The design of the positioning groove 12 facilitates the positioning and installation of the rigid reinforcement shell 2. The front surface of the positioning piece 22 slightly protrudes from the front surface of the wooden board 1 to better cover the gap between the rigid reinforcement shell 2 and the wooden board 1. The positioning piece 22 is provided with a second mounting hole 221. The second fastener passes through the second mounting hole 221 and connects to the bottom wall of the positioning groove 12 of the wooden board 1. The second fastener serves to assist in fixing the rigid reinforcement shell 2 to the wooden board 1, further improving the connection stability of the rigid reinforcement shell 2 to the wooden board 1.

[0036] Reference Figure 2-3 The top and bottom hinge 3 is provided with a connecting piece 31, and the positioning piece 22 of the rigid reinforcement shell 2 is provided with a connecting groove for the connecting piece 31 to be embedded. The connecting piece 31 and the connecting groove of the rigid reinforcement shell 2 are fixed by a connecting piece, and the connecting piece is located in the positioning groove 12 and is adjacent to the second fastener. Specifically, the connecting piece is a bolt, and a connecting hole 311 is provided on the connecting piece 31, and a threaded hole 222 corresponding to the connecting hole 311 and matching the bolt is provided on the connecting groove. The bolt threadably connects the top and bottom hinge 3 to the rigid reinforcement shell 2. In other embodiments, other connection methods can also be used between the top and bottom hinge 3 and the rigid reinforcement shell 2. However, in this embodiment, the connecting piece 31 is preferably provided on the positioning piece 22, and the second mounting hole 221 is provided adjacent to the threaded hole 222, which is more convenient for workers to install.

[0037] Reference Figure 4 The cabinet structure also includes a vertical plate 4. The vertical plate 4 is another component of the cabinet structure and is connected to the wooden board 1. A support member 5 is provided between the vertical plate 4 and the rigid reinforcement shell 2. The support member 5 supports the side end of the rigid reinforcement shell 2 so that the force of the rigid reinforcement shell 2 can be dispersed to the vertical plate 4, thereby sharing the force exerted by the door leaf of the top and bottom hinge 4 on the wooden board 1, further reducing the load on the wooden board 1, and better avoiding problems such as the wooden board 1 bursting.

[0038] In this embodiment, see Figure 1 and Figure 4 The side profile of the rigid reinforcement shell 2 is arc-shaped, and a decorative block 6 is provided between the vertical plate 4 and the rigid reinforcement shell 2. The decorative block 6 blocks the gap between the arc-shaped side profile of the rigid reinforcement shell 2 and the vertical plate 4 after installation, thereby improving the overall aesthetics of the cabinet structure. Of course, the side profile of the rigid reinforcement shell 2 can also be square. When the side profile of the rigid reinforcement shell 2 is square and flush with the vertical plate 4, the decorative block 6 can be omitted. This solution adopts a rigid reinforcement shell 2 with arc-shaped sides because the arc-shaped side profile is the optimal solution for different installation conditions.

[0039] The technical solution provided by the present invention is introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
