Description

Technical Field

[0001] The utility model relates to the field of aluminum profiles, in particular to a special-shaped aluminum profile connection structure. Background Art

[0002] Aluminum profiles are a product application of aluminum alloys. Whether made of aluminum alloy or pure aluminum, they are called aluminum profiles. Aluminum profiles are made by hot-melting and extruding aluminum bars to create various cross-sectional shapes. Special-shaped aluminum profiles, also known as non-standard aluminum profiles, are customized to meet the needs of individual customers' equipment and products, providing one-on-one services including mold fabrication, material selection, surface treatment, and subsequent CNC machining. Therefore, as an important industrial material, aluminum profiles have a wide range of applications, encompassing various fields, including construction, industry, and automotive.

[0003] An existing patent (application number 201821813667.3) discloses a precision connection structure for special-shaped aluminum profiles, comprising a first profile plate, a second profile plate, a slider, and a connecting frame. The top of the first profile plate is fixedly connected to the bottom of the slider, the top of the slider is slidably connected to the inside of the second profile plate, the top of the connecting frame is fixedly connected to a card box, a first partition is fixedly connected between the two sides of the connecting frame's inner cavity, and a pressure plate is fixedly connected to one side of the connecting frame's inner cavity and at the top and bottom of the first partition. The utility model relates to the technical field of special-shaped aluminum profiles. This precision connection structure for special-shaped aluminum profiles can effectively connect the profiles, solving the problems of easy deformation and low precision of the profiles during welding, greatly improving the fixing effect of the profile plates, and having high fixing strength, making it easier for users to disassemble and assemble the profile plates, reducing the labor intensity of the staff, avoiding friction when the first and second profile plates are fixed, and increasing the overall service life.

[0004] When existing special-shaped aluminum profiles need to be connected by a connecting structure, the connecting structure is relatively simple. Not only are the special-shaped aluminum profiles easy to shake and deviate, but the fixing strength after connection is also relatively general, which affects the stability of the special-shaped aluminum profiles after connection.

At this time, the spring on the plug is stressed, thereby driving the connecting plate to retract inward, and then continue to push the plug, so that the protrusion on the connecting plate can just fit into the No. 1 groove on the inner wall of the No. 1 special-shaped aluminum profile, and after the plug is fully pushed in, the No. 1 auxiliary docking block on the connecting base can also just fit in. Insert it into the No. 1 docking slot. Similarly, the connecting device on the other side of the connecting base is also connected to the No. 2 special-shaped aluminum profile, so that the No. 1 special-shaped aluminum profile and the No. 2 special-shaped aluminum profile are docked together. Finally, the fixing bolts are screwed into the bolt holes on the insert block to further lock the special-shaped aluminum profile and the connecting base. In addition, the double docking and clamping method of the insert block and the auxiliary docking block also facilitates the connection between the connecting base and the special-shaped aluminum profile. At the same time, after the connection, the connection part of the special-shaped aluminum profile and the connecting base also has better stability. BRIEF DESCRIPTION OF THE DRAWINGS
