As further improvement of the utility model, the end of described nail core is provided with the nail core head, is provided with one in the described nail body and is used to block the screens portion of following closely core head.
As further improvement of the utility model, described nail core comprises the nail core head and the nail core body of one, is provided with fracture portion between nail core head nail core body, and the sectional area of fracture portion is less than the sectional area of nail core body.
As further improvement of the utility model, the shape of cross section of described fracture portion should be arranged to the shape that is easy to rupture, and the shape of cross section of the fracture portion in the utility model is cubic fusiformis.
As further improvement of the utility model, the sectional area of described nail core head is greater than the sectional area of nail core body.
As further improvement of the utility model, described nail core head is discoid or oblateness.
As further improvement of the utility model, described nail core is provided with anti-slip tank by bottom 2/3rds length.
As further improvement of the utility model, described nail body head is an oblate spheroid shape.
As further improvement of the utility model, described nail body all adopts stainless steel material to make with the nail core.
The utility model compared with prior art, have the following advantages: (1) is owing to be provided with at least two annular grooves on the nail body of the present utility model, thereby formed the uniform bending part of at least two groups, expansion cydariform foot during staking, solved closed type rivet because the nail core head in the nail body, is riveted the difficult problem of back cydariform deficiency; (2) end sealing of nail body, the water-tight after can realizing riveting, and anti-non-magnetic shim core head comes off, riveting is more firm, has solved twin drum snap riveting nail because the difficult problem that the nail body is bored a hole and leaked; (3) nail body of the present utility model and nail core all adopt the stainless steel material manufacturing, and the intensity height is corrosion-resistant.

Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in the figure, described high strength sealing drum type rivet mainly is made up of nail body 1 and nail core 2 two-part.Described nail body 1 is the tubular body of boring, the sealing of one end opening one end, and described nail core 2 is solid constructions, nail core 2 penetrates the nail body 1 and is stuck from opening one end of following closely body 1 and can not skid off; Opening one end of described nail body 1 is provided with nail body head 1a, and the external diameter of nail body head 1a is greater than the external diameter of nail body body 1b, and the outer wall of nail body body 1b is provided with two annular groove 1c that parallel.
As shown in Figure 4, can not skid off for nail core 2 is stuck in the nail body 1, the end of described nail core 2 is provided with nail core head 2a, is provided with one in the described nail body 1 and is used to block the 1d of screens portion that follows closely core head 2a.
Shown in Fig. 3,4,6, described nail core 2 comprises the nail core head 2a and the nail core body 2c of one, separate in order to make nail core 2 be convenient to fracture after riveted joint is finished, be provided with the 2b of fracture portion between described nail core head 2a and the nail core body 2c, the sectional area of the 2b of fracture portion is less than the sectional area of nail core body 2c.The shape of cross section of the 2b of fracture portion should be arranged to the shape that is easy to rupture, and just at the position at fracture portion 2b place, in the utility model, the shape of cross section of the 2b of fracture portion preferably is set to cubic fusiformis with the disconnection position of guaranteeing to follow closely core 2.
Shown in Fig. 1,3,4, described nail core 2 is provided with anti-slip tank 2d by bottom 2/3rds length.When staking, the riveting gun three-jaw can match with anti-slip tank 2d, prevents that effectively the riveting gun three-jaw from sliding on nail core 2, is convenient to the staking operation.
Shown in Fig. 1,2,5,6, described nail body head 1a is an oblate spheroid shape, and this oblate spheroid shape is good-looking after riveted joint is finished, and especially surperficial smoother burr etc. can not occur.
Shown in Fig. 2,3, described nail core head 2a is discoid or oblateness.The sectional area of described nail core head 2a is greater than the sectional area of nail core body 2c.The purpose of She Zhiing is like this, and the utility model is when riveted joint workpiece 3, and nail core 2 can both obtain a good location with nail body 1.
Concrete applicable cases of the present utility model is as follows:
Shown in Fig. 5,6, during riveted joint, in two workpiece to be riveted, 3 punchings 4, to follow closely in the body body 1b patchhole 4, the riveting gun three-jaw is caught nail core 2, under the staking effect of riveting gun, nail core head 2a compressing nail body body 1b, the expanded drum of stressed bending becomes drum type to nail body body 1b owing to the existence of annular groove 1c, thereby two workpiece 3 are firmly compressed pinning, because nail core head 2a is positioned at an end of nail body 1 sealing, it comes off shockproof waterproof never in conjunction with closely, thereby can guarantee to rivet firmly never becoming loose between the utility model and two workpiece 3.
