Description

A kind of rivet

Technical field

The utility model belongs to machinery industry, relates to a kind of linkage structure, refers in particular to a kind of rivet.

Background technique

At present, in structure connected, widely used riveted structure had: the self-plugging rivet of metal, nylon rivet etc.Loosing core is the rivet that a class blind riveting is used, but must use special tool, rivets such as hand riveter.During riveted joint, the rivet blind rivet is spurred by special-purpose riveting gun, and rivet body is expanded, and plays the riveted joint effect.This class rivet is specially adapted to the riveted joint occasion that conventional rivets (must rivet from the two sides) is adopted in inconvenience.But because self-plugging rivet must use special tool, efficiency of assembling is not high.In addition, nylon rivet is again Plastic Rivets.Common Plastic Rivets all adopt elasticity and memory performance preferably nylon make, with respect to the common metal rivet, nylon rivet has specific characteristics in chemical property and physical property, be better than conventional rivet at insulating properties and corrosion-resistant soda acid etc., and quality own is low weight, with respect to screw, nylon rivet is more convenient on assembling speed, need not any instrument and can finish assembling.But generally not as conventional rivets and screw, reliability is not high enough for its pulling capacity.

The model utility content

The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of quick, safe and reliable Novel rivet that assembles with not enough.

The utility model is achieved through the following technical solutions: a kind of rivet comprises rivet nut and blind rivet.This rivet nut comprises rivet nut main body, rivet nut cap and snapping section, and this rivet nut cap is arranged on the top of rivet nut main body, and this snapping section is arranged on the outward edge of this rivet nut main body bottom and has elasticity, and a center hole runs through rivet nut main body and the rivet nut cap of this rivet nut.This blind rivet comprises blind rivet main body and blind rivet cap, and this blind rivet cap is arranged on the top of this blind rivet main body, and this blind rivet main body is inserted in the center hole of rivet nut.

Further, this rivet nut main body and blind rivet main body are cylindrical body.

Further, this rivet nut cap and blind rivet cap are circle or polygonal.

Further, the external diameter of this rivet nut cap is greater than the external diameter of rivet nut main body.

Further, the external diameter of this blind rivet cap is greater than the external diameter of blind rivet main body.

Further, the center hole of this rivet nut in the aperture at its rivet nut cap place greater than in the aperture at rivet nut main body place, blind rivet is inserted after, the blind rivet cap sinks in this rivet nut cap.

Further, have screw thread on the inwall of the center hole of this rivet nut, the outer wall of this blind rivet main body has screw thread, tightens by screw thread between this blind rivet and the rivet nut to cooperate.

Further, the bottom of this rivet nut main body has breach.

With respect to prior art, the rivet assembling that the utility model provides is quick and safe and reliable.

Embodiment

Please consult simultaneously Fig. 1 and Fig. 2, wherein, Fig. 1 is the schematic perspective view of the rivet of the utility model preferred embodiment, and Fig. 2 is the sectional drawing after the rivet assembling shown in Figure 1.This rivet 100 comprises rivet nut 10 and blind rivet 20.This blind rivet 20 can be inserted in the rivet nut 10.

Please consult simultaneously Fig. 3 and Fig. 4, wherein, Fig. 3 is the stereogram of the rivet nut 10 of rivet 100 shown in Figure 1, and Fig. 4 is the sectional drawing of the rivet nut 10 of rivet 100 shown in Figure 3.This rivet nut 10 comprises rivet nut main body 11, rivet nut cap 12 and snapping section 13.This rivet nut main body 11 is cylindrical body.This rivet nut cap 12 is arranged on the top of rivet nut main body 11, is circle, and the external diameter of this rivet nut cap 12 is greater than the external diameter of rivet nut main body 11.This snapping section 13 is arranged on the outward edge of these rivet nut main body 11 bottoms, has elasticity, can be to center generation deformation under the effect of external force.Further, center hole 14 runs through rivet nut main body 11 and the rivet nut cap 12 of this rivet nut 10.The bottom of this rivet nut main body 11 has breach 15.

See also Fig. 5, it is the planimetric map of the blind rivet 20 of rivet 100 shown in Figure 1.This blind rivet 20 comprises blind rivet main body 21 and blind rivet cap 22.This blind rivet main body 21 is Cylindrical object.This blind rivet cap 22 is arranged on the top of this blind rivet main body 21, is circle, and its external diameter is greater than the external diameter of blind rivet main body 21.This blind rivet main body 21 closely cooperates with the center hole 14 of rivet nut 10, need to apply certain power and this rivet nut 10 could be inserted or extracted to blind rivet 20.

Further, for attractive in appearance, greater than in the aperture at rivet nut main body 11 places, namely there is a shoulder in the aperture at these rivet nut cap 12 places in the center hole 14 of this rivet nut 10, blind rivet 20 is inserted after, blind rivet cap 22 sinks in this rivet nut cap 12.

In addition, as the distressed structure of above preferred embodiment, this rivet nut cap 12 and blind rivet cap 22 can also replace with the polygonals such as square.And, having screw thread on the inwall of this center hole 14, the outer wall of this blind rivet main body 21 has screw thread, makes between this blind rivet 20 and the rivet nut 10 to tighten by screw thread to cooperate.

During use, will play the riveted joint effect in the rivet nut 10 insertion mounting holes, blind rivet 20 is inserted to play in the rivet nuts 10 and is reinforced and anti-loose effect.With respect to prior art, rivet assembling of the present utility model is quick and safe and reliable.

The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
