Abstract

The invention relates to a self-locking drum-shaped blind rivet. The rivet comprises a rivet body and a rivet core in the rivet body, wherein a first inner hole and a second inner hole which are axially distributed along the rivet body are formed in the rivet body; the second inner hole is communicated with the first inner hole; the aperture of the second inner hole is less than that of the first inner hole; a locking step is formed at the junction of the second inner hole and the first inner hole; the rivet body is convexly provided with a rivet edge corresponding to the end part for forming the second inner hole; one end of the rivet core is convexly provided with a rivet head; one side of the rivet core corresponding to the rivet head is provided with a first cylinder and a second cylinder; one end of the second cylinder is connected with the rivet head, and the other end of the second cylinder is connected with the second cylinder through a locking slot; the rivet core gets out of the first inner hole and the second inner hole in the rivet body corresponding to the other end for arranging the rivet head; and the rivet head is contacted with the end of the rivet body. The rivet has the advantages of high strength, high rigidity, high vibration resistance, suitability for riveting of aeronautical materials, wide application range, safety and reliability.

Description

technical field [0001] The invention relates to a blind rivet, in particular to a self-locking drum-shaped blind rivet, in particular to a blind rivet which can be used in the aviation field. Background technique [0002] At present, the domestic aviation industry is developing rapidly, and the basic requirements for aviation materials are: light material, high strength, and good rigidity; therefore, higher requirements are put forward for the riveting field of aviation materials. The rivets currently on the market cannot meet the strong and durable joint loads required by aviation. [0003] At present, the rivets in the aviation field are such as wire drawing blind rivets. After the rivets are riveted, the cup on the mandrel can remain in the rivet body, which can have a good fastening effect and has a certain shock resistance. However, the riveting surface of this rivet is small, and its ability to resist sliding between two sheets may be good, but its ability to resist s...
