Abstract
The invention discloses a self-clinching bolt which comprises a nut, a first screw and a second screw, wherein the nut is fixedly connected above the first screw, and the second screw is fixedly connected under the first screw; a conical blind hole is formed under the first screw, and a conical bulge is arranged above the second screw and is matched with the blind hole. By the above method, before the self-clinching bolt carries out self clinching, the length of the first screw is increased through the second screw, so that the bolt is facilitated to connect two fastening pieces before riveting; after self clinching, the second screw falls off from the first screw, and riveting point cannot be too large; the fastening effect is good, and the using is more convenient.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of pressing-riveting bolt.
Background technique
Present stage, in the process of pressing, need to be mutually permanently connected by two links by pressing-riveting bolt, the screw rod bearing capacity of this pressing-riveting bolt must can meet the requirement connecting fastening effect, and the end of screw rod does not have purposes in the process pressed, just conveniently fix before pressing.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of better effects if that presses, bearing capacity stronger, use convenient pressing-riveting bolt.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of pressing-riveting bolt, nut, the first screw rod and the second screw rod, described nut is fixedly connected on the top of described first screw rod, described second screw rod is fixedly connected on the below of described first screw rod, the below of described first screw rod is provided with a cone-shaped blind hole, and the top of described second screw rod is provided with a conical protrusions, and described projection matches with described blind hole.
In a preferred embodiment of the present invention, described first screw rod is polished rod.
In a preferred embodiment of the present invention, described second screw rod is polished rod.
In a preferred embodiment of the present invention, the external diameter of described second screw rod is the 3/5-4/5 of described first outer screw diameter.
In a preferred embodiment of the present invention, the length of described first screw rod is greater than the length of described second screw rod.
The invention has the beneficial effects as follows: before pressing-riveting bolt of the present invention presses, the second screw rod adds the length of the first screw rod, facilitate bolt before riveted joint, connect two fastening pieces, and after pressing, second screw rod comes off from the first screw rod, riveting point can not be caused too large, and fastening effect is good, uses convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of pressing-riveting bolt one of the present invention preferred embodiment.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of pressing-riveting bolt, nut 1, first screw rod 2 and the second screw rod 3, described nut 1 is fixedly connected on the top of described first screw rod 2, described second screw rod 2 is fixedly connected on the below of described first screw rod 3, the below of described first screw rod 2 is provided with a cone-shaped blind hole 21, the top of described second screw rod 3 is provided with a conical protrusions, and described projection matches with described blind hole 21.
Described first screw rod 2 is polished rod.
Described second screw rod 3 is polished rod.
The external diameter of described second screw rod 3 is the 3/5-4/5 of described first screw rod 2 external diameter.
The length of described first screw rod 2 is greater than the length of described second screw rod 3.
Be different from prior art, before pressing-riveting bolt of the present invention presses, the second screw rod adds the length of the first screw rod, facilitates bolt before riveted joint, connect two fastening pieces, and after pressing, the second screw rod comes off from the first screw rod, riveting point can not be caused too large, fastening effect is good, uses convenient.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
