Profiled bar skeleton T-shaped groove type angle connection fastening corner frame structure

Abstract

The invention discloses a profiled bar skeleton T-shaped groove type angle connection fastening corner frame structure. The structure comprises a T-shaped head two-end insertion structural body and a ratchet punching piece; the T-shaped head two-end insertion structural body comprises a first plug body and a second plug body; the two plug bodies are intersected by an included angle; a connection reinforcing rib is arranged between the first plug body and the second plug body for powerfully resisting deformation; the ratchet punching piece is positioned on a plug body on the edge of the connection reinforcing rib; ratchets are arranged on two sides of the ratchet punching piece; and a fastening hole is formed in middle for connecting with a general fastening piece. The structure is low in cost, convenient to machine, suitable for ultralarge-batch automatic production, flexible in purchase and simple and fast in operation, is an ideal accessory for producing and assembling such objects as furniture, booths and indoor and outdoor decoration objects by structural parts containing T-shaped grooves, is firm and reliable in disassembly and assembly and not liable to damage each part, can be recycled to reduce wastes, and is wide in application.

[0002] When assembling gorgeous and beautiful appearance objects on the complex shape skeleton model built, the assembly is very particular about the process and sequence. If one step is wrong, many steps are required to compensate. If a defect occurs in one place, many related parts need to be disassembled. , Time-consuming, labor-intensive, not free, prone to error and accidental damage, requires skilled and prioritized technical individuals to install correctly and efficiently, and the installation cost is also high. The society urgently needs to be fast, convenient, with small technical constraints, and not easy to make mistakes. If you make a mistake, it is easy to correct. You can install and assemble gorgeous and beautiful appearance objects by yourself without training proficiency. The frame of the frame is easy to loose locally or produce displacement or gaps, etc. This is because the existing connection method lacks sufficient clamping force, or there are parts that cannot be prevented from falling off in the mechanism. The deformed or displaced frame structure will affect the outer surface. In terms of performance, at the same time, the application of fasteners and standard parts on special-shaped materials also has many local problems that are not easy, inconvenient, affect the appearance and the hidden danger of scratching and damage. The grade is low and it is difficult to produce high-quality products.
