Description

Technical Field

[0001] The utility model relates to a connecting component of a furniture plate body, in particular to a furniture plate connecting piece. Background Art

[0002] The plate connector is a widely used furniture plate connector component. The mutual connection and fixation of furniture plates are mainly realized by the plate connector, which mainly includes hidden connectors and external support bracket connectors. The hidden connector is usually an expansion type plate connector. When the eccentric wheel rotates, the connector head generates a pulling force on the connecting rod, and expands outward under the action of this pulling force, so that the undercut teeth on the outside of the connector head are clamped on the inner side of the plate body, so that the connector is hidden inside the connected furniture plate body. The hidden connector is easy to install and has a good connection tightness, but it is not conducive to further improving the bearing capacity of the connection; the external support bracket connector is to use a bracket set on the outside of the plate body, and then cooperate with the mounting seat on the other plate body to realize the connection of the two plates. After the external support bracket is hung, the bracket itself is prone to axial loosening, shaking around the hanging point or radial loosening, etc., which affects the reliability of the fixation between the plates. Therefore, the existing plate connector structure still needs to be further improved. Utility Model Content

The integrally formed intermediate clamping plate 2 and the bottom plate 3 are bonded to the furniture board 4 through the corresponding first adhesive layer 21 and second adhesive layer 30 to play a connecting role. As an example, the lengths of the left plate portion and the right plate portion are set to 1-2 times the height of the intermediate clamping plate 2, which is beneficial to ensuring the supporting effect of the bottom plate 3 during bottom installation.

[0031] The connector 1 includes a plurality of first connectors 10 and a plurality of second connectors 14. The first connectors 10 and the second connectors 14 are installed at the same horizontal height, and the corresponding placement holes 20 are arranged at the same horizontal height.
