Abstract

The utility model provides a rivet. One end of the rivet is made into a cap head. The other end is made into an extensible hole post. In addition, internal screw threads are arranged inside the hole post. The rivet is characterized in that the corresponding point of the inner edge of the cap head of the rivet and the outer wall of the extensible hole post is provided with a plurality of fixing pinna sheets. The fixing pinna sheets are made into knife edge surfaces with sharp front ends.

Description

Rivet

The utility model relates to the part of a kind of machinery or furniture, is a kind of rivet, particularly a kind ofly is provided with a rivet hole on the object of wooden, plastics system or metal tabular or hollow shape, as punch riveting one have interior threaded hole rivet.

Existing rivet mainly utilizes the volution external diameter of an adjacent cap position to form non-just round shape, in the punch riveting process, the eccentric profile close attachment that makes this volution is in by the rivet hole of the object of riveted, but this structure, because non-just round external diameter often differs too big with the shape of rivet hole, to cause the distortion of rivet hole, but, then will increase more trouble if rivet hole is made into and non-positive toroidal.

Main purpose of the present utility model is to propose a kind of rivet of novel structure, to overcome the shortcoming of existing rivet.

This practical main technical schemes is to make the plurality of fixed accessory pinna at the cap head inner edge of this rivet and column outer wall corresponding part, extendible hole, fixedly accessory pinna is arranged to the sharp-pointed knife edge face of front end, make rivet directly scratch and embed when the punch riveting to form around the rivet hole and the fixing identical shaped knife edge shape engagement groove of accessory pinna by this knife edge face, allow knife edge shape fixedly accessory pinna can hold in the mouth to pull firm, securely and be sticked in the knife edge shape engagement groove.

Main feature of the present utility model is that an end of this rivet is arranged to the cap head, the other end is arranged to open-ended Kong Zhu, and internal thread is set in Kong Zhu, particularly be provided with if fixing accessory pinna in the cap head inner edge of this rivet and column outer wall corresponding part, extendible hole, this fixedly accessory pinna be arranged to the sharp-pointed knife edge face of front end.

Major advantage of the present utility model be than existing rivet combine firmlyer with rivet hole, firm, with screw when knot lock, or else can rotate and the situation that can't lock.

Further specify as follows below in conjunction with drawings and Examples:

Fig. 1 is a schematic perspective view of the present utility model.

Rivet 10 cap heads 11 open-ended hole posts 12 interior threaded holes 13 are accessory pinna 14 fixedly

Rivet arrangement of the present utility model, as shown in Figure 1, one end of this rivet 10 is arranged to cap head 11, the other end is arranged to open-ended hole post 12, and internal thread 13 is set in hole post 12, as the fixing usefulness of screw lock knot, particularly the cap head inner edge at this rivet is provided with as if individual fixedly accessory pinna 14 with extendible hole post 12 outer wall corresponding parts, this fixedly accessory pinna 14 be arranged to the sharp-pointed knife edge face of front end.

Rivet of the present utility model is applied in a lot of occasions, as to the riveted between riveted, tabular body and the hollow shape body between the tabular body etc.When riveted is operated, at first will need the plate of riveted to make a call to a rivet hole, the external diameter of the extendible hole post 12 of its aperture and rivet 10 is suitable, with rivet 10 direct punch rivetings in this rivet hole, then another piece is needed the rivet hole of the plate of riveted or hollow sheeting and the rivet hole place of plate of rivet has been installed involutory, go into to tighten with one piece of screw thread spike dowel, then riveted is finished.

Claims

A kind of rivet, one end of this rivet is arranged to the cap head, and the other end is arranged to open-ended Kong Zhu, and internal thread is set in Kong Zhu, it is characterized in that being provided with if fixing accessory pinna in the cap head inner edge of this rivet and column outer wall corresponding part, extendible hole, this fixedly accessory pinna be arranged to the sharp-pointed knife edge face of front end.
