Mounting accessories for quick connection of various industrial aluminum profiles

technical field

The invention belongs to the field of machinery and non-ferrous metal processing, and in particular relates to a series of installation accessories for quick connection of various industrial aluminum profiles.

Background technique

Industrial aluminum profiles refer to all aluminum profiles except for building doors and windows, curtain walls, interior and exterior decoration and aluminum profiles for building structures. When the aluminum profile is assembled into a product, profiles of different specifications are used according to different load bearings, and matching aluminum profile accessories are used. Aluminum profile accessories are connectors specially used for fastening and connection of industrial aluminum profile frame systems. After years of development, my country already has relatively complete aluminum profile structure installation accessories.

However, with the continuous rise of social labor costs, high-speed and high-efficiency requirements are put forward when a large number of large-scale aluminum profile frame equipment are assembled. In the past, industrial aluminum profile connections were mainly connected by bolts and nuts, special fasteners, connectors, and corner pieces.

It has achieved the expected effect of fast and reliable connection, saved the time for building the platform equipment framework, and improved work efficiency.

This patent proposes the use of an eccentric wheel quick clamping device to realize faster disassembly and assembly of industrial aluminum profiles without using any tools. The principle is that when the eccentric wheel rotates 180° in the positive direction along the circumference, the center of the eccentric circle moves upward by two eccentric distances, so that the eccentric wheel produces a downward pressing force on the workpiece and the eccentric wheel pull rod produces an upward reverse tension force on the workpiece, which can clamp the workpiece between the eccentric wheel and the tie rod. Workpiece Ⅱ6; when the eccentric wheel reversely rotates 180° along the circumference, the center of the eccentric circle moves downward by two eccentric distances, so that the eccentric wheel generates an upward pressure on the fixed workpiece and the eccentric pull rod produces a downward counter-pressing force on the clamped workpiece, which can make the clamped workpiece exert a downward force on other parts, thereby realizing the clamping function. 1. Simulate fixed workpiece Ⅱ12. Utilize this eccentric wheel clamping principle to realize quick connection and clamping between two aluminum profiles.
