Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to a three-in-one board joint structure. Background Technology

[0002] The three-in-one connector is a hardware component for panel furniture, consisting of an eccentric wheel, a connecting rod, and a pre-embedded nut. It achieves vertical, horizontal, or cross-connection of panels through threaded fastening (as disclosed in the prior art with application number CN201120020465.5). This type of three-in-one connector is used to connect two mutually perpendicular panels. When three panels are involved (one each in the X, Y, and Z directions), two traditional three-in-one connectors are required. In addition, the traditional three-in-one connector requires a pre-embedded nut. The connecting rod is connected to the nut to fix one panel to the connector, while the other panel is fixed to the connector by clamping the eccentric wheel to the connecting rod. Therefore, the connection strength of the first panel depends on the installation accuracy of the pre-embedded nut, while the connection reliability of the other panel is a kind of "tension" along the axis of the connecting rod. There is no tight connection between the connecting rod and the mounting hole on the panel for the connecting rod to pass through. It can be seen that the existing three-in-one connector is a loose connection and does not have high connection strength, stability, and reliability. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a three-plate connection method with high connection strength.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a three-in-one plate connection structure, characterized in that the three plates to be connected are a horizontal plate, a vertical partition plate, and a back plate, wherein the surfaces of two of the three plates are perpendicular to each other. The plate connection structure includes a horizontal hole nut, which includes a connecting section and an elastic section. A through groove is formed in the middle of the elastic section, and the through groove divides the elastic section into two symmetrically arranged connecting strips with arc-shaped outer surfaces. A screw hole 1 coaxial with the horizontal hole nut is formed on the connecting section, and two screw holes 2 perpendicular to the horizontal hole 1 are formed on the connecting strip. A reserved hole parallel to the surface of the back plate is formed on the end face of the horizontal plate. The horizontal hole nut is fixed to the horizontal plate by inserting a screw 1 through the screw hole 1, the horizontal hole nut is fixed to the back plate by inserting a screw 2 through the two coaxial screw holes 1, and the horizontal hole nut is fixed to the vertical partition plate by inserting a screw 3 through the other two coaxial screw holes 2.

[0005] Furthermore, the horizontal plate has alignment holes for mounting screws two and three on its surface. The alignment holes are perpendicular to the reserved holes and penetrate through the reserved holes.

[0006] Compared with the prior art, the present invention has the following advantages:

[0007] 1. By using a horizontal hole nut and three screws, three plates located on a three-dimensional plane can be connected at a common diagonal position. The number of hardware parts used is much less than that of existing technologies, and the structure is relatively simple.

[0008] 2. Because the transverse hole nut has a through groove, a gap is formed between the two connecting strips. As a metal material, the two connecting parts have a certain elasticity when under force. This elasticity can not only improve the ease of installing screws, but also pre-tighten screws two and three, reduce the gap between the screw and the thread of the threaded hole, and thus improve the reliability of the three-plate connection.

[0009] 3. All three boards are fixed with screws. The screws can be screwed into the boards, which greatly improves the connection strength and reliability compared to the traditional insertion and clamping method. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3As shown, the three wooden or plastic boards to be connected are a horizontal board 1, a vertical partition 2, and a back board 3. The surfaces of two of the three boards are perpendicular to each other. The board connection structure includes a horizontal hole nut 4, which includes a connecting section and an elastic section. A through groove 5 is opened in the middle of the elastic section, dividing the elastic section into two symmetrically arranged connecting strips 6 with arc-shaped outer surfaces. A screw hole 7 coaxial with the horizontal hole nut 4 is opened on the connecting section, and two screw holes 8 perpendicular to the screw holes 7 are opened on the connecting strip 6. A reserved hole parallel to the surface of the back board 3 is opened on the end face of the horizontal board 1. The horizontal hole nut 4 is fixed to the horizontal board 1 by screw 9 through screw hole 7, and the horizontal hole nut 4 is fixed to the back board 3 by screw 20 through two coaxial screw holes 7. The horizontal hole nut 4 is fixed to the vertical partition 2 by screw 31 through two other coaxial screw holes 8.

[0016] Alignment holes for mounting screws 10 and 11 are provided on the surface of the horizontal plate 1. The alignment holes are perpendicular to the reserved holes and penetrate the reserved holes.

[0017] First, make a pre-drilled hole on the end face of the horizontal plate 1 corresponding to the horizontal hole nut 4. Then, make two alignment holes. The position of the alignment holes can be determined by comparing the horizontal hole nut on the horizontal plate. After the holes are made, splice the three plates into a three-dimensional plate joint state, insert the horizontal hole nut 4, then drive in screw 9, and adjust the position of the horizontal hole nut to ensure that the screw hole 2 is coaxial with the alignment hole. Then drive in screw 10, but do not tighten it during the screwing process. Then screw in screw 11, but do not tighten it. Finally, make small adjustments to screw 10 and screw 11 to achieve small tightening multiple times, and complete the splicing of the three plates.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
