Abstract

The invention discloses a thickness-adjustable bolt. The thickness-adjustable bolt comprises a screw head and screw rods. The screw head is of a regular hexagon stereoscopic structure. The center axis of the screw head is connected with the screw rods. The number of the screw rods is two. One screw rod is connected with the screw head, the surface of the thin screw rod which is integrally machined and manufactured is provided with a thread, and the thin screw rod and the screw head form a whole which is a complete bolt body; another screw head is an individual which is independently machined and manufactured, the surface of the thick screw rod with a cylindrical cavity hole in the center axis is provided with a thread, and the surface of the inner circle of the cavity hole of the thick screw rod is provided with a thread which is matched with the thread on the surface of the thin screw rod; the section diameter of the thin screw rod is equal to that of the cavity hole of the inner circle of the thick screw rod, and the thick screw rod can be screwed on and wraps the surface of the thin screw rod through the threads. Due to the mode, the thickness-adjustable bolt is novel in structure, the screw rods can be thickened and reinforced as required, and the thickness-adjustable bolt is high in practicability and stability and has high economic benefits and wide application prospects.

Description

A kind of bolt of adjustable thickness
Technical field
The present invention relates to fixed component field, particularly relate to a kind of bolt of adjustable thickness.
Background technique
Bolt is the one of mechanical parts, and the cylindrical threaded fastening piece of adapted nut, is made up of spiral shell head and screw rod, need and nut screw connection, for being fastenedly connected two parts with through hole, but, the screw rod thickness of bolt is in the market and immobilizes, and cannot overstriking reinforce.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of bolt of adjustable thickness, can carry out overstriking reinforcing as required to screw rod.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the bolt providing a kind of adjustable thickness, is characterized in that, comprising: spiral shell head, screw rod, described described spiral shell head is regular hexagon stereochemical structure, the screw rod described in the connection of central axis place of described spiral shell head; Described screw rod has two, and one is be connected with described spiral shell head, the micro screw of one processing and fabricating, and surface is provided with screw thread, and the entirety that described micro screw becomes with spiral shell head group is also a complete bolt; Another is the individuality of independent processing and fabricating, and central axis has the thick screw rod in a cylindrical cavity hole, and surface is provided with screw thread, and the cavity bore inner peripheral surface of described thick screw rod is provided with screw thread, and the screw thread on this screw thread and micro screw surface matches; Wherein, described micro screw diameter of section is identical with described thick screw rod inner ring cavity bore diameter of section, by screw thread, thick screw rod can be screwed on and be coated on micro screw surface.
In a preferred embodiment of the present invention, described spiral shell head and screw rod material are round steel.
In a preferred embodiment of the present invention, described micro screw is solid cylinder body structure, and diameter of section is identical with described thick screw cavity bore dia.
In a preferred embodiment of the present invention, described thick screw rod has a cylindrical cavity hole, can just screw in described micro screw in hole, and thick screw rod race diameter is less than the width of described spiral shell head.
In a preferred embodiment of the present invention, described thick screw rod is identical with micro screw length, and all coupling has the nut matched with it.
The invention has the beneficial effects as follows: novel structure of the present invention, can carry out overstriking reinforcing to screw rod as required, practical, steadiness is high, has higher economic benefit and application prospect widely.
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 bolt one preferred embodiment of a kind of adjustable thickness of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, spiral shell head; 2, screw rod; 3, micro screw; 4, thick screw rod; 5, micro screw.
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 bolt for adjustable thickness, is characterized in that, comprising: spiral shell head 1, screw rod 2, and described described spiral shell head 1 is regular hexagon stereochemical structure, the screw rod 2 described in the connection of central axis place of described spiral shell head 1; Described screw rod 2 has two, and one is be connected with described spiral shell head 1, the micro screw 3 of one processing and fabricating, and surface is provided with screw thread, and the entirety that described micro screw 3 and spiral shell head 1 form also is a complete bolt; Another is the individuality of independent processing and fabricating, and central axis has the thick screw rod 4 in a cylindrical cavity hole 5, and surface is provided with screw thread, and cavity bore 5 inner peripheral surface of described thick screw rod 4 is provided with screw thread, and the screw thread on this screw thread and micro screw 3 surface matches; Wherein, described micro screw 3 diameter of section is identical with described thick screw rod 4 inner ring cavity bore 5 diameter of section, by screw thread, thick screw rod 4 can be screwed on and be coated on micro screw 3 surface.
Be different from prior art.
In another embodiment, described spiral shell head 1 is round steel with screw rod 2 material, aboundresources, and processing is simple, and technology maturation, fabricating cost is low.
In another embodiment, described micro screw 3 is solid cylinder body structure, and diameter of section is identical with described thick screw rod 4 cavity bore 5 diameter, and thick screw rod 4 is rotatable is coated on micro screw 3 outer ring, carries out reinforcing screw rod 2 overstriking.
In another embodiment, described thick screw rod 4 has a cylindrical cavity hole 5, just can screw in described micro screw 3 in hole, and thick screw rod 4 race diameter is less than the width of described spiral shell head 1, ensures that spiral shell head 1 is greater than the diameter of screw rod 2 all the time.
In another embodiment, described thick screw rod 4 is identical with micro screw 3 length, and all coupling has the nut matched with it.
Novel structure of the present invention, overstriking reinforcing can be carried out as required to screw rod, during operation, only inner ring cavity bore need be established threaded thick screw rod, slowly rotate micro screw of screwing on, until be coated on micro screw surface, seamless paste synthesizes a thicker screw rod, practical, steadiness is high, has higher economic benefit and application prospect widely.
