Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific drawings.

[0021] As shown in the figure, the high-strength closed drum rivet mainly consists of two parts: a nail body 1 and a nail core 2 . The nail body 1 is a hollow tubular body with one end open and the other closed. The nail core 2 is a solid structure, and the nail core 2 penetrates into the nail body 1 from the open end of the nail body 1 and is stuck without slipping. Out; one end of the opening of the nail body 1 is provided with a nail body head 1a, the outer diameter of the nail body head 1a is greater than the outer diameter of the nail body 1b, and the outer wall of the nail body 1b is provided with two parallel annular recesses Slot 1c.

[0022] Such as Figure 4 As shown, in order to prevent the nail core 2 from slipping out in the nail body 1, the end of the nail core 2 is provided with a nail core head 2a, and the nail body 1 is provided with a Part 2a of the card p...

Abstract

The invention relates to a high-intensity sealed drum type rivet. The high-intensity sealed drum type rivet comprises a rivet body and a rivet core, and is characterized in that: the rivet body is a tubular body with a hollow inner part, one end of the rivet body is opened while the other end is sealed, and the rivet core is punched in the rivet body from the opening of the rivet body and blocked without sliding out; the open end of the rivet body is provided with a rivet body head part, the outside diameter of the rivet body head part is more than that of the rivet body main body, and the outer wall of the rivet main body is provided with at least two parallel annular grooves. The advantages of a sealed rivet and a dual-drum type rivet are combined in the invention, and the high-intensity sealed drum type rivet has the advantages of the sealed rivet and the dual-drum type rivet; therefore, the workpiece can be avoided loosing and falling after riveted, furthermore, the rivet operation is simple and convenient and the noise is low.

Description

technical field [0001] The invention relates to a rivet, in particular to a high-strength closed drum-shaped rivet used for riveting parts of aircraft, automobiles, motor vehicles and the like. Background technique [0002] At present, in the riveting of aircraft, automobile, motor vehicle parts and other products, ordinary closed rivets and double-drum rivets are mostly used for riveting. Defects that are easy to loosen and fall off, thus damaging the riveted product and affecting product quality and performance. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings in the prior art, and provide a high-strength closed drum rivet with ingenious and reasonable structure, which organically combines the advantages of closed rivets and double drum rivets, and has both closed rivets and closed drum rivets. The functional advantages of the double-drum rivet can avoid the adverse consequences of the workpiece loosen...
