Inner support anti-rotation anti-disengagement thread sleeve special for aluminum profile and installation method of inner support anti-rotation anti-disengagement thread sleeve

Abstract

The invention discloses an inner support anti-rotation anti-disengagement thread sleeve special for an aluminum profile. The back end of a main body is provided with a base. An annular boss is arranged in the position, on the front portion of the base, of the outer side wall of the main body. The outer side wall of the annular boss is a regular polygon. The front end of the main body is provided with a boss. The front portion of the main body is internally provided with a hole. The front end of the main body is internally provided with an annular groove. The back portion of the main body is internally provided with an extrusion locking hole. The installation method of the inner support anti-rotation anti-disengagement thread sleeve comprises the following steps that a, a first through hole and a second through hole are formed in the two side walls of the aluminum profile; b, the front end of the thread sleeve penetrates into the aluminum profile from the first through hole; c, a head punching head is inserted into the hole, and a bottom punching head is inserted into the extrusion locking hole; and d, punching is conducted on the aluminum profile through the bottom punching head, and the thread sleeve is firmly installed on the square aluminum profile. The inner support anti-rotation anti-disengagement thread sleeve special for the aluminum profile has the advantages that the structure is simple; the design is reasonable; the structure of the thread sleeve is simplified; the production and using cost is reduced; and the installation convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of screw sleeves and installation methods thereof, and more specifically relates to the technical field of screw sleeves for aluminum profiles and installation methods thereof. Background technique [0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot-melt extrusion. When other parts need to be installed on aluminum profiles, the current common installation and connection methods generally include welding, riveting or threaded connections. When using welding methods When connecting and installing, due to the poor welding performance of aluminum, the welding cost is high, and the connection strength is low, and other parts cannot be disassembled after welding on the aluminum profile, which is very inconvenient; Profiles are usually hollow and thin-walled parts, so the riveting strength is low, and it is easy to loosen, and the riveted parts cannot be disassemb...

Problems solved by technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot-melt extrusion. When other parts need to be installed on aluminum profiles, the current common installation and connection methods generally include welding, riveting or threaded connections. When using welding methods When connecting and installing, due to the poor welding performance of aluminum, the welding cost is high, and the connection strength is low, and other parts cannot be disassembled after welding on the aluminum profile, which is very inconvenient; Profiles are usually hollow and thin-walled parts, so the riveting strength is low, and it is easy to loosen, and the riveted parts cannot be disassembled, which is very inconvenient; The bolts fix the parts that need to be fixed on the aluminum profile. Since the aluminum profile is generally a hollow and thin-walled part, the threaded connection is easy to loosen and the connection strength is poor.

In addition to the above-mentioned several common connection methods, there are currently some connections that use screw sleeves. This connection method has better connection stability than the above-mentioned connection methods, but the current common screw sleeve connections still have connections. The firmness is not very ideal, and it is easy to loosen in the axial direction after a period of use, and it is easy to rotate

At the same time, the structure of the common screw sleeves is relatively complicated, which not only increases the processing and manufacturing costs, but also makes the installation process of the screw sleeves more cumbersome, which is not very convenient to operate, which affects the installation efficiency, and the installed screw sleeves are not very firm.
