a combined titanium alloy rivet comprises a rivet core and a rivet sleeve, wherein the rivet core comprises a rivet cap and a rivet rod; the nail sleeve is sleeved outside the nail rod, and the tail end of the nail rod forms a nail tail after being punched; the nut root of the nail nut is provided with an annular positioning groove; one end of the nail sleeve is a positioning end, and the other end is a pressure-bearing end; the positioning end penetrates through the object to be connected and enters the positioning groove, and the pressure-bearing end is clamped on the surface of the object to be connected; at least one annular first clamping groove is respectively arranged on the inner side surface and the outer side surface of the nail sleeve, and an anti-skid damping structure is arranged in the first clamping groove.
Preferably: the bottom section of the positioning groove is arc-shaped, the inner side groove wall is provided with a second clamping groove, and an anti-skid damping structure is arranged in the second clamping groove.
Preferably: the section of the pressure-bearing end is a right triangle with the inner height and the outer bottom, and the included angle between the bevel edge and the object to be connected is smaller than 45 degrees.
Preferably: the bearing surface of the bearing end is provided with a plurality of convex positioning rings.
Preferably: the nail core and the nail sleeve are made of titanium alloy materials.
According to the utility model, the nail core and the objects to be connected are protected in the stamping process through the structural design of the nail sleeve, so that the influence caused by stamping is reduced, and the mounting effect is improved.
1. The positioning groove enables the nail sleeve and the nail core to be positioned quickly in the stamping preparation stage, and the effect of preventing the dislocation movement of the nail core is achieved after the installation is completed, so that the nail core is prevented from being loosened after long-time use.
2. The anti-skid damping structure in the first clamping groove and the second clamping groove can be matched with the nail sleeve to protect the object to be connected and the nail core, and the installation effect is improved.
3. The structure of the pressure-bearing end is not only convenient for guiding stamping forming (section shape), but also can improve the integrity of the rivet after forming and further improve the installation effect.

FIG. 2 is a schematic view of a staple core structure;
FIG. 3 is a schematic view of the structure of the nail sleeve;
fig. 4 is a construction diagram of the bearing end face.
In the figure: 1. a nail sleeve; 11. a first clamping groove; 12. a positioning ring; 2. a nail cap; 21. a positioning groove; 22. a second clamping groove; 3. and (5) nailing the rod.
Detailed Description
The structure of the present utility model will now be fully described in connection with the specific embodiments so that those skilled in the art will fully understand and practice the utility model.
As shown in fig. 1 and 2, a combined titanium alloy rivet comprises a rivet core and a rivet sleeve 1, wherein the rivet core is made of titanium alloy materials and comprises a rivet head 2 and a rivet rod 3; the nail sleeve 1 is sleeved outside the nail rod 3, and the tail end of the nail rod 3 forms a nail tail after punching; the nut root of the nail cap 2 is provided with an annular positioning groove 21; one end of the nail sleeve 1 is a positioning end, and the other end is a pressure-bearing end; the positioning end passes through the object to be connected and enters the positioning groove 21, and the pressure-bearing end is clamped on the surface of the object to be connected; the inner side surface and the outer side surface of the nail sleeve 1 are respectively provided with two annular first clamping grooves 11, the two annular first clamping grooves are respectively corresponding to two objects to be connected, and an anti-slip damping structure is arranged in each first clamping groove 11.
Preferably: the bottom section of the positioning groove 21 is arc-shaped, the inner side groove wall is provided with a second clamping groove 22, and an anti-skid damping structure is arranged in the second clamping groove 22. The second clamping groove 22 enables the positions of the nail sleeve 1 and the nail cap 2 to be more stable through the built-in protective damping structure.
Preferably: the section of the pressure-bearing end is a right triangle with the inner height and the outer bottom, and the included angle between the bevel edge and the object to be connected is smaller than 45 degrees (shown as theta). The structure of the oblique side can guide the nail rod 3 when it is deformed by punching.
Preferably: the bearing surface of the bearing end is provided with a plurality of convex positioning rings 12. The positioning ring 12 improves the integrity of the nail sleeve 1 and the nail rod 3 after the punching is finished, and further improves the installation effect of the rivet.
