Description

An integrated intelligent synchronous two-way locking furniture panel connector

technical field

The utility model relates to a connecting part of a furniture board body, in particular to an integrated intelligent synchronous two-way locking type furniture board body connector with strong installation stability.

Background technique

The panel connector is a very widely used furniture panel connecting part at present. It mainly realizes the fixed connection between the furniture panels through the sequential connection of the eccentric wheel, the connecting rod and the connector embedded in the panel body. Existing furniture panel connectors are mainly divided into two types: expansion type and fastening type. The difference between the two is that when the connecting rod is displaced under the pull of the eccentric wheel, the expansion type connector will expand outward, making the connector The outer inverted tooth is clamped on the inner side of the board body; while the fastening type connector does not produce shape change, but realizes the fixing of the board body through the connection between the eccentric wheel and the connecting rod. However, there are two major technical defects in the traditional expansion-type panel connectors. First, the expansion-type plate body connector adopts the separate structure of the eccentric wheel, the connecting rod and the connecting head, and the materials of the above-mentioned parts are different, and they are also produced by separate processing. Therefore, during the assembly of the above components, it often occurs that the board cannot be connected smoothly due to the excessive dimensional tolerance or position tolerance of each part. The above situation greatly affects the reliability of the connector installed on the board, which will cause the Body connectors require additional assembly testing at the factory. Second, the inner cavity of the connecting head of the traditional expansion-type plate body connector and the connecting rod, and the connecting rod and the eccentric wheel are all sliding connections. When the eccentric wheel, connecting rod and other parts become loose, the connecting rod will be separated The connection between it and the connector is loose. This phenomenon will cause the expansion part of the connector to reset under the influence of the elastic recovery force due to the lack of top pressure, causing the connected board to loosen because the connector cannot be smoothly clamped on the inside of the board, which greatly affects The stability of the fixing between the boards is improved. In addition, when the eccentric wheel rotates and drives the connecting rod to move, the connecting head is also subjected to the pulling stress of the connecting rod. When the expansion part of the connecting head fails to expand in time, the connecting head will slide out of the plate with the pulling of the connecting rod In addition to causing gaps in the board body after the connectors are fixed, it will also seriously affect the normal connection of the board body. Therefore, the existing board connector structure still needs to be further improved.
