A self-expanding semi-solid mounting rivet

Abstract

The invention relates to the field of rivets, in particular to a self-expansion semi-solid installation rivet. The self-expansion semi-solid installation rivet comprises a guide sleeve, a rivet body,a driving structure, a sealing structure, a fixing structure, an anti-falling structure and a limiting structure, wherein a limiting structure used for limiting the rivet body is arranged at one end,close to the guide sleeve, of the rivet body, a driving structure used for driving the limiting structure is arranged in the rivet body, and the rivet body is sleeved with an anti-falling structure for pressure relief. According to the self-expansion semi-solid installation rivet, the driving structure inside the rivet body facilitates driving of the limiting structure to abut against a hole of anobject through the driving structure, so that the rivet body can be quickly limited, and meanwhile, the driving structure is matched with the limiting structure, so that the rivet body can be detached after being installed, so that the recycling efficiency of the rivet body is greatly improved; the anti-falling structure is matched with the rivet body, so that looseness of the fixing structure caused by shaking of the rivet body is avoided, and then the fixing quality of the rivet is greatly improved.

Description

technical field [0001] The invention relates to the field of rivets, in particular to a self-expanding semi-solid installation rivet. Background technique [0002] A rivet is a nail-shaped object used to connect two parts (or components) with a through hole and a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference. The connection of the rivet improves the distance between the two objects. The fastening performance between the rivets is weaker than the rivets that are screwed and installed by machines when the rivets are manually operated, so the expansion rivets are widely used. [0003] However, the connection between the traditional expansion semi-solid installation rivet and the plate is easy to cause damage to the plate, the installation and operation flexibility of the rivet is poor, and the rivet offset and loosening are prone to occur when the traditional wet plates are connected by rivets. In view of this, the presen...
