Abstract
The invention discloses a hollow rivet with a double-side countersunk head. The rivet comprises a rivet bar and a rivet body, wherein a central through-hole is formed in the rivet body; the rivet bar is sleeved with the rivet body through the central through-hole; a rivet head integrated with the rivet bar is arranged at the front end of the rivet bar; the end surface of the rivet body is flat and in a conical shape; one end, opposite to the rivet head, of the rivet body is arranged to form an inverted conical shape with the flat end surface. The hollow rivet with the double-side countersunk head has the advantages that the riveting speed is high, the surface of a riveted sheet metal part is guaranteed to be smooth and flat, the appearance is attractive, the rivet head cannot be separated from the rivet rod and left in the rivet body, and accordingly, potential safety hazards caused by rivet head falling can be effectively eliminated.
Description
Technical field
The present invention relates to the technical field of rivet, more particularly relate to the technical field of hollow rivet.
Background technique
Rivet is easy to use, riveted joint speed is fast, high working efficiency, very convenient the thin-walled metal sheet is connected and fixed, general welding type fixation is a good substitution for, welding type is often with electrical spark, the operation place higher at ask for something just can not be used, moreover the thin-walled metal sheet is welded to connect fixing, and its weld strength also is difficult to guarantee, rivet generally is applicable to electronics, communication, automobile, field such as space flight and aviation, its use amount is also very big, and present rivet is after riveted joint is finished, and its ailhead can be stayed riveted joint place, block riveted holes, the deficiency of its existence is: in use, be the danger that this ailhead might occur coming off on the one hand, the ailhead that comes off is if fall in the casing of being riveted, just cause the phenomenon of casing inner electronic equipment short circuit easily, thereby can cause great potential safety hazard; After being riveted joint on the other hand, rivet body is positioned at the high projection in the metal sheet surface of being riveted, and makes by the metal sheet air spots after the riveted joint slidingly, has both influenced attractive in appearancely, can bring inconvenience to use again.
Summary of the invention
Purpose of the present invention provides a kind of riveted joint speed fast in order to solve above-mentioned deficiency exactly, and the no ailhead in riveted joint back is residual, can effectively eliminate safe hidden trouble, and can guarantee the smooth two-sided countersunk head hollow rivet of metal sheet smooth surface of being riveted.
The technical solution that the present invention adopts in order to solve the problems of the technologies described above is as follows:
Two-sided countersunk head hollow rivet, comprise rivet bar and rivet body, rivet body offers central through bore, rivet body is nested with on rivet bar by this central through bore, it is the ailhead of one that the front end of described rivet bar is provided with rivet bar, this ailhead be cone-shaped and its end face straight, an end relative with ailhead is arranged to the straight inverted cone shape of end face on the described rivet body.
The straight end face diameter of described ailhead is than the big 2-4 millimeter of diameter of rivet body central through bore.
The diameter of the straight end face of described rivet body is than the big 2-4 millimeter of diameter of the straight end face of ailhead.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: it has the advantage that conventional rivets has, riveted joint speed is fast, because two opposing sides of ailhead and rivet body are straight end face, after riveted joint is finished, rivet body can be under the squeezing action of ailhead and external force, its part can be pressed into by in the riveted joint metal sheet deep hole, thereby guaranteed that the metal sheet smooth surface of being riveted is smooth, help attractive in appearance, because ailhead and rivet bar are monolithic construction and fracture port are not set each other, ailhead is under tension when riveted joint, be forced in the rivet body hole and produce plastic deformation and in the rivet body hole, extract out, ailhead can not break away from rivet bar and remain in the rivet body, thereby eliminate the potential safety hazard that comes off and cause owing to ailhead effectively.

Fig. 2 is the present invention riveted joint effect structural representation after finishing.
Embodiment
By illustrated in figures 1 and 2, two-sided countersunk head hollow rivet, comprise rivet bar 1 and rivet body 2, rivet body 2 offers central through bore 5, rivet body 2 is nested with on rivet bar 1 by this central through bore 5, the front end of described rivet bar 1 is provided with rivet bar 1 and is the ailhead 3 of one, this ailhead 3 be cone-shaped and its end face straight, being beneficial to ailhead 3 extends to draw and wears, also be beneficial to simultaneously rivet body 2 and produce plastic deformation, and the shaping after the rivet body 2 generation plastic deformations, an end relative with ailhead 3 on the described rivet body 2 is arranged to the straight inverted cone shape 4 of end face, the straight end face diameter of ailhead 3 is advisable than the big 2-4 millimeter of diameter of rivet body 2 central through bores 5, and the diameter of rivet body 2 straight end faces is advisable than the big 2-4 millimeter of diameter of ailhead 3 straight end faces.
Claims (3)
1. two-sided countersunk head hollow rivet, comprise rivet bar and rivet body, rivet body offers central through bore, rivet body is nested with on rivet bar by this central through bore, it is characterized in that: it is the ailhead of one that the front end of described rivet bar is provided with rivet bar, this ailhead be cone-shaped and its end face straight, an end relative with ailhead is arranged to the straight inverted cone shape of end face on the described rivet body.
