AI Technical Summary
Existing concealed connectors are inefficient in small-batch custom production and are prone to damaging drilling equipment. They also fail to meet the need for flexible adjustment of screw hole positions and quantities, affecting installation strength.
Design an aluminum profile concealed connector, which adopts a pre-drilled hole and a limiting groove structure. The pre-drilled hole is provided with a guide mounting hole. Through the cooperation of the limiting groove and the retaining strip, the screw hole can be flexibly adjusted and the drilling process can be stabilized.
It improves the flexibility and installation strength of small-batch customized production, avoids damage to equipment and materials, ensures the accuracy and consistency of drilling, and maintains high installation strength.
