Description

Technical Field

[0001] The utility model relates to the technical field of wooden board connectors, in particular to a hidden multi-angle wooden board connector. Background Art

[0002] As people's living standards improve, wood products are becoming increasingly diverse. These products require assembly and connection during production. Traditionally, wood planks are connected using nails, which takes up a lot of space during handling or transportation, increasing transportation costs and making them susceptible to damage.

[0003] After searching, the application with patent publication number CN208749738U discloses an invisible connector for wooden boards, including a female part and a male part connected to each other, the female part including a strip base and a first limit block and a second limit block respectively arranged on both sides of the strip base, a strip groove is formed between the first limit block, the second limit block and the strip base, the male part is provided with an M-shaped spring piece, the middle part of the M-shaped spring piece is interference fit with the strip groove, so that the firmness of the connection can be improved through mortise and tenon joints.

[0004] However, due to the setting of the mortise and tenon joints and the M-shaped spring piece, the shapes of the strip grooves and the M-shaped spring piece must be highly precise, so that the stability of the connection can be guaranteed when performing the dovetail joint. The structural accuracy is high, and the production and manufacturing are inconvenient, time-consuming and labor-intensive. At the same time, after the connection, the wooden board can only be disassembled by destroying it, which is inconvenient to disassemble it for recycling.

[0005] Therefore, we proposed a hidden multi-angle wood panel connector. Utility Model Content
