[embodiment]
The following example is to further explanation of the present utility model and supplements, and does not constitute any limitation the utility model.
As shown in Fig. 1 ~ Fig. 5, staking self-plugging rivet assembly of the present utility model comprises nail cover 1, nail bar 2 and pushing packing ring 3.Described nail cover 1 is sheathed on outside described nail bar 2, and described nail bar 2 makes for pull nail overlap 1 dimensional deformation and forms tympanic part 17, to rivet.Broad outlines of the present utility model is, the outer wall of described nail cover 1 is provided with and receives pressure point 11, the self-locking property of pressure and strengthening nail bar 2 and nail cover 1 is received by multiple spot, and by arranging shoulder hole 12 on nail cover 1, nail bar 2 arranges cut-off neck slot 21, thus make the fracture of staking type self-plugging rivet assembly of the present utility model controlled, and can stealthyly install.
Particularly, as shown in Figure 3, nail cover 1 of the present utility model by nail thread die cutting portion 13, shoulder hole portion 14, tube 15, nail cover head 16 one-body molded.Described nail thread die cutting portion 13 is provided with internal thread.Described shoulder hole portion 14 is adjacent with described nail thread die cutting portion 13, is provided with shoulder hole 12 in it.The aperture of described shoulder hole 12 is greater than the internal diameter in described nail thread die cutting portion 13, thus makes nail cover 1 the most weak in this shoulder hole 12 place intensity, is the most easily out of shape and forms tympanic part 17.Described tube 15 is adjacent with described shoulder hole portion 14, and the internal diameter of described tube 15 is less than the internal diameter of described shoulder hole 12.Described nail cover head 16 is adjacent with described tube 15, described nail cover head 16 is consistent with the counter sink shape on to be riveted, thus make when following closely cover 1 and inserting the counter sink on to be riveted, the end face of described nail cover head 16 can be mutually concordant with the surface of described to be riveted, thus reach stealthy object from the appearance.The external diameter of described nail thread die cutting portion 13, shoulder hole portion 14, tube 15 is consistent, and it forms complete circumferential outer surface.The face size of described nail cover head 16 is greater than the external diameter in described nail thread die cutting portion 13.
As shown in Figure 2, described nail bar 2 is one-body molded by nail club head 22, nail bar screw section 23, polished rod portion 24 and clamping part 25.Described nail club head 22 is in cylindric, and its diameter is greater than the internal diameter in described nail thread die cutting portion 13, thus make nail cover 1 be sheathed on nail bar 2 outer time, follow closely the end abutment of cover 1 on the supporting surface of described nail club head 22.In the present embodiment, the external diameter of described nail club head 22 is consistent with the external diameter in described nail thread die cutting portion 13.The central authorities of described nail club head 22 are located in described nail bar screw section 23 in vertical state, the outer wall of described nail bar screw section 23 is provided with outside thread, the internal thread in this outside thread and described nail thread die cutting portion 13 matches, thus nail bar screw section 23 can be threaded with nail thread die cutting portion 13.The length in described nail thread die cutting portion 13 is consistent with the length of described nail bar screw section 23.Described polished rod portion 24 is in cylindric, and it is adjacent with described nail bar screw section 23.The diameter in described polished rod portion 24 is consistent with the external diameter of described nail bar screw section 23.Described clamping part 25 is adjacent with described polished rod portion 24, and it carries out staking for connecting anchor rifle.Between described clamping part 25 and described polished rod portion 24, be provided with cut-off neck slot 21, thus make nail bar 2 the most weak in the intensity at this cut-off neck slot 21 place, to be the easiliest pulled off at cut-off neck slot 21 place.Described cut-off neck slot 21 can be arranged to multiple formation, and in the present embodiment, described cut-off neck slot 21 is annular groove, and it is located between clamping part 25 and polished rod portion 24 ringwise.Carry out staking for ease of connecting anchor rifle, the outer wall of described clamping part 25 is provided with fastening teeth 252 and interference tooth 251.Described fastening teeth 252 is near the end of clamping part 25, and it is for clamping riveting gun.Described interference tooth 251 interval is located between described fastening teeth 252 and cut-off neck slot 21, and it overlaps 1 and nail bar 2 vent stem interference fit for making nail.。
As shown in Figure 1, described pushing packing ring 3 is sheathed on the interference tooth 251 of the clamping part 25 of described nail bar 2.As shown in Figure 4, described pushing packing ring 3 is provided with the conical surface 31 of band tapering and the circumferential surface 32 with pushing packing ring parallel to an axis, and the described conical surface 31 forms ladder with described circumferential surface 32.
As shown in Figure 1, when nail bar 2 assembles with nail cover 1, first nail cover 1 is inserted in nail bar 2 outside, make nail overlap 1 and be connected with one end end thread of nail bar 2, the other end vent stem connects.Then pushing packing ring 3 is assemblied on the clamping part 25 of nail bar 2 in an interference fit, and makes the interior edge face of pushing packing ring 3 and described to follow closely the end face overlapping head 16 mutually concordant.When following closely cover 1 and having assembled with nail bar 2, the receipts pressure point 11 of nail cover 1 carries out multiple spot and receives pressure and play self-locking effect, just define staking type self-plugging rivet assembly of the present utility model by this.During use, as shown in Figure 5A, first assembly is inserted the counter sink of thing to be riveted, then block fastening teeth 252 with the anchor rifle of band staking function, withstand pushing packing ring 3 and carry out staking.As shown in Figure 5 B, because the shoulder hole 12 place intensity of following closely cover 1 is minimum, in staking process, shoulder hole 12 place is out of shape at first and forms tympanic part 17.Simultaneously, nail bar 2 is in staking process, its cut-off neck slot 21 staking is pulled off to the end of pushing packing ring 3 owing to being subject to enough pulling force, makes nail bar 2 at cut-off neck slot 21 place fracture (as shown in Figure 5 C), thus realizes the object controlling fracture site.And because the fracture of following closely bar 2 is with described to follow closely the end face overlapping head 16 mutually concordant, therefore it has stealthy function.Staking type self-plugging rivet assembly of the present utility model solves that existing rivet assembly efficiency of assembling is low, poor in self, shortcoming without stealthy function, not only self-locking property is good for it, fracture is controlled, and can stealthyly assemble, and can lightweight packages be alleviated, reduce assembly cost, and be convenient to dismounting, use very convenient.
Although disclosed the utility model by above embodiment, but scope of the present utility model is not limited thereto, under the condition not departing from the utility model design, above each component can be replaced with the similar or equivalent element that art personnel understand.
