DETAILED DESCRIPTION

[0032] The present subject matter pertains to improved approaches for a screw-free and highly stable coupling structure between adjacent boards. Embodiments of the present subject matter are discussed below with reference to FIGS. 1-11.

[0033] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present subject matter. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without some of these specific details. In addition, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. Moreover, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the subject matter rather than to provide an exhaustive list of all possible implementations. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the details of the disclosed features of various described embodiments.

Embodiment I

[0034] As shown in FIGS. 1 to 5, the board coupling structure of this embodiment can comprise a first board 1 and a second board 2 that can be inserted and interlocked into each other. The first board 1 and the second board 2 can be rectangle or square boards. When they are coupled, the first board 1 and the second board 2 can be perpendicular to each other. According to some embodiments, the first board 1 and the second board 2 can be respectively formed with at least one strip-shaped rib 11 and at least one strip-shaped groove 21 that can be inserted or plug-in into each other, so that the first board 1 and the second board 2 can only move in the insertion direction.

[0035] The strip-shaped rib 11 of this embodiment can be disposed on one of the circumferential side surfaces 12 of the first board 1, whereas the strip-shaped groove 21 can be disposed on the inner side wall of the second board 2 and near an edge of the second board (2) along the length direction of the edge. According to some embodiments, the shape of the strip-shaped groove 21 can be adapted to the strip rib 11, with one end of the strip groove 21 forming an opening, and the other end being closed. As such, it can facilitate the insertion of the first board 1 and the second board 2 to form the coupling structure.

[0036] According to some embodiments, the circumferential side 12 of the first board 1 can extend outwardly to form a longitudinally extending arm 111 that is perpendicular to the circumferential side 12. In this embodiment, two transversely extending arms 112 can extend laterally on opposite sides of the longitudinally extending arm 111, and the transversely extending arms 112 and the longitudinally extending arm 111 are perpendicular to each other. The longitudinally extending arm 111 and the transversely extending arms 112 can jointly form a strip-shaped rib 11, so that the cross-section of the strip-shaped rib 11 forms a double-T shape. With the double-T shaped cross-section, the contact area between the strip-shaped rib 11 and the stripe-shaped groove 12 is larger. On the one hand, the board coupling structure can improve the bite and make the structure more stable and reliable. On the other hand, it can also facilitate the waterproofing of the connection between the two boards.

[0037] As shown in FIG. 5, all the transversely extending arms 112 of this embodiment can adopt the same length. According to some embodiments, the length of the laterally extending arms 112 can be different according to different needs, which also has the advantages of stable structure and good waterproof performance.

[0038] In this embodiment, the first board 1 can be the bottom board of the cabinet, and the second board 2 can be the side board of the cabinet. When interlocking with each other, the first board 1 can be horizontally placed, and then the second board 2 can be placed in a vertical position. A user can backwardly insert the stripe-shaped rib 11 from the open end of the stripe-shaped groove 21 until the rear end of the stripe-shaped rib 11 and the closed end of the stripe-shaped groove 21 abut, thereby completing the coupling of the first board 1 and the second board 2.

[0039] According to some embodiments, the board coupling structure can also be applied to the connection or joint between other adjacent boards of the cabinet. For example, the first board 1 can be the right side board of the cabinet and the second board 2 can be the front side board of the cabinet, which can be interlocked with each other. By eliminating the need of any connection accessories, the present coupling structure can be convenient and quick. Correspondingly, the disassembly can be convenient as the coupling structure is screw-free. In addition, the coupling structure can be adopted between other boards or panels, such as the left side board and the front side board, the left side board and the rear side board.

Embodiment II

[0040] As shown in FIGS. 6 and 7, in this embodiment, the transversely extending arm 112 can be provided on one side surface of the longitudinally extending arm 111, and the two transversely extending arms can be spaced out at predetermined intervals. The longitudinally extending arm 111 and the transversely extending arms 112 can jointly form the strip-shaped rib 11. As such, the cross-section of the strip-shaped rib 11 is F-shaped. In this embodiment, the length of the two transversely extending arms 112 may be the same or different. The F-shaped, plug-in coupling structure can have the advantage as described herein.

Embodiment III

[0041] As shown in FIG. 8, there are three transversely extending arms 112 in this embodiment that are spaced out at intervals. Compared with Embodiment II, it has one more transversely extending arm 112, which can further increase the contact area and improve the biting or engagement degree of the plug-in coupling structure. It can be more stable, reliable, and waterproof.

Embodiment IV

[0042] As shown in FIG. 9, the longitudinally extending arm 111 and the transversely extending arm 112 of this embodiment can jointly form a cross-shaped structure. Accordingly, the strip-shaped rib 11 is a cross-shaped structure that can be engaged with a cross-shaped groove in four different directions, thereby effectively improving the structural stability and waterproof performance.

Embodiment V

[0043] As shown in FIG. 10, the longitudinally extending arm 111 and the transversely extending 112 of this embodiment can jointly form a T-shaped structure. Accordingly, the strip-shaped rib 11 is a T-shaped structure that can be engaged with a T-shaped groove, which is relatively easy to manufacture and the structural strength can still be optimized.

Embodiment VI

[0044] In FIG. 11, the longitudinally extending arm 111 and the laterally extending arm 112 of this embodiment can jointly form an L-shaped structure. Accordingly, the strip-shaped rib 11 is L-shaped. Even though the contact surface of the coupling structure is relatively small and the structural stability is relatively low, the manufacturing of the coupling structure is relatively easy, which can be suitable for the board connections that do not require high structural strength.

[0045] The above are only the preferred embodiments of the present subject matter. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present subject matter, various modifications or improvements can be made to the present subject matter, such as in other applications. For example, the first board and the second board may not be perpendicular to each other, and the specific shape of the clamping portion is not limited to the disclosed shapes, and these are all considered to be within the protection scope of the present subject matter.

[0046] It is to be understood that even though numerous characteristics and advantages of various embodiments of the present subject matter have been set forth in the foregoing description, together with details of the structure and function of various embodiments of the subject matter, this disclosure is illustrative only. In some cases, certain subassemblies are only described in detail with one such embodiment. Nevertheless, it is recognized and intended that such subassemblies may be used in other embodiments of the subject matter. Practitioners skilled in the art will recognize many modifications and variations.
