Rivet for riveting hollow profiles

Abstract

The invention discloses a rivet for riveting hollow profiles. The lower end of a rivet bar is provided with a rivet head, and a rivet shell is tubular, with openings in the both ends; the rivet shellis arranged at the part, close to one side of the rivet head, of the rivet bar in a sleeving manner, and the upper part of the rivet shell is provided with a support part; the upper end of a pressingsleeve is provided with a first chamfer, and the outside wall of the pressing sleeve is provided with an annular baffle; the pressing sleeve is located at the lower part of the annular baffle, and isconical; the inside wall of the opening position at the upper end of the support part of the rivet shell is provided with a second chamfer corresponding to the conical bottom of the pressing sleeve; the pressing sleeve is provided with a through hole, and arranged on the rivet bar through the through hole of the pressing sleeve in the sleeving manner; and the conical bottom of the pressing sleeveis clamped in the second chamfer of the support part of the rivet shell. The rivet disclosed by the invention has the advantages that the rivet can be used for inner support of a single hollow profile, riveting and inner support of two hollow profiles, and riveting and inner support of the hollow profiles and plates; and the rivet is used widely, and the installation and operation are very convenient.

Description

technical field [0001] The present invention relates to the technical field of rivets, more specifically to the technical field of blind rivets. Background technique [0002] The rivet is a widely used nail-shaped connecting fastener. It is generally used for the connection and fastening of thin-walled aluminum profiles. During the riveting process of the rivet, the rivet uses its own deformation or interference under the external force of the rivet gun Connection The riveted parts are fixedly connected together. At present, the common rivets on the market mainly include R-shaped rivets, blind rivets and blind rivets, etc. The blind rivets are generally composed of nail shells and nail rods. The rod is riveted to make the nail shell bulge and deform, so as to achieve the purpose of riveting. However, the current common blind rivets are generally only suitable for the connection and fixation between two plates. When it is necessary to rivet and fix two hollow profiles, it is...

Problems solved by technology

However, the current common blind rivets are generally only suitable for the connection and fixation between two plates. When it is necessary to rivet and fix two hollow profiles, it is necessary to set up a larger rivet on the side wall of one of the hollow profiles. The large avoidance hole is used for the gun head of the riveting gun to penetrate into the hollow profile for riveting operation. However, in this way, not only the riveting operation is very inconvenient, but also the avoidance hole must be opened on the side wall of the hollow profile, thus affecting The structural strength of hollow profiles is reduced, and the common hollow profiles are generally thin-walled aluminum profiles, so they are prone to extrusion deformation or bending deformation when bearing loads, so it is usually necessary to support the interior of hollow profiles, but the current common blind rivets They only have the connection function, not the support function, and are not suitable for the connection and internal support of hollow profiles.
