Abstract
The invention discloses a double-end screwing bolt which comprises a screw head and a screw, wherein the screw head is a hexagonal screw head with a regular-hexagon transverse cross section; the bottom of the screw head is fixedly connected with the screw; the vertical center axis of the screw and the center axis of the screw head stay on the same straight line; the screw comprises a thread part and a screwing part; the thread part is of a cylindrical structure with thread on the outer surface; the screwing part is connected with the screw bottom below the thread part; the screwing part is of a hexagonal prism structure with a regular-hexagon transverse cross section; the thread part and the screwing part form an integrated structure. Through the way, the two ends of the bolt disclosed by the invention can be screwed; when the screw head is screwed, the screwing part at the screw bottom assists the screwing operation, thus the screwing stress is dispersed, the screwing is easier, and the practicability is higher.
Description
Technical field
The present invention relates to fixed component field, particularly relate to a kind of bolt that can double end twisting.
Background technology
Bolt is the one of machine components, and the cylindrical threaded securing member of adapted nut, by head and a screw rod class securing member dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole, at present, bolt arrangement on market is similar, mostly be solid construction, twisting mode is all by spanner, spiral shell head-clamp to be lived, and then screws, twisting mode is single, and twisting is very painstaking, spanner stress point on spiral shell head is few, operates very not light.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of bolt that can double end twisting, can carry out the operation of double end twisting, when Luo Touchu carries out twisting, utilize the twisting portion of screw rod bottom to assist twisting work, make twisting force dispersion, twisting is lighter, practical.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of bolt that can double end twisting is provided, it is characterized in that, comprise: spiral shell head, screw rod, described spiral shell head is that its lateral cross section is orthohexagonal hexagonal spiral shell head, spiral shell head bottom is fixedly connected with described screw rod, the vertical central shaft of described screw rod and the central shaft of described spiral shell head are point-blank, screw rod comprises threaded portion and twisting portion two parts, described threaded portion is that outer surface arranges threaded cylindrical structure, described twisting portion is connected to the screw rod bottom that below, threaded portion is positioned at, twisting portion is that cross section is orthohexagonal six prism structures, threaded portion and twisting portion form integrative-structure.
In a preferred embodiment of the present invention, described spiral shell head, screw rod material are carbon steel.
In a preferred embodiment of the present invention, described twisting portion and the vertical central axis of threaded portion are located on the same line.
In a preferred embodiment of the present invention, the regular hexagonal cross section of described twisting portion is connected to the circular cross-section of threaded portion in being.
In a preferred embodiment of the present invention, the height of described twisting portion equals the height of spiral shell head.
The invention has the beneficial effects as follows: twisting operation all can be carried out in bolt provided by the present invention two, when Luo Touchu carries out twisting, utilize the twisting portion of screw rod bottom to assist twisting work, make twisting force dispersion, twisting is lighter, practical.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described 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, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of bolt one preferred embodiment that can double end twisting of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1-spiral shell head, 2-screw rod, 21-threaded portion, 22-twisting portion.
Detailed description of the invention
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain 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 bolt that can double end twisting, it is characterized in that, comprise: spiral shell head 1, screw rod 2, described spiral shell head 1 is that its lateral cross section is orthohexagonal hexagonal spiral shell head, spiral shell head 1 bottom is fixedly connected with described screw rod 2, the vertical central shaft of described screw rod 2 and the central shaft of described spiral shell head 1 are point-blank, screw rod 2 comprises threaded portion 21 and twisting portion 22 two parts, described threaded portion 21 is threaded cylindrical structure for outer surface arranges, described twisting portion 22 is connected to screw rod 2 bottoms that 21 belows, threaded portion are positioned at, twisting portion 22 for cross section be orthohexagonal six prism structures, threaded portion 21 forms integrative-structure with twisting portion 22.
Described spiral shell head 1, screw rod 2 materials are carbon steel.
Described twisting portion 22 is located on the same line with the vertical central axis of threaded portion 21.
The regular hexagonal cross section of described twisting portion 22 is connected to the circular cross-section of threaded portion 21 in being, do not affect normal upper use of bolt.
The height of described twisting portion 22 equals the height of spiral shell head 1.
Twisting operation all can be carried out in bolt provided by the present invention two, when Luo Touchu carries out twisting, utilizes the twisting portion of screw rod bottom to assist twisting work, makes twisting force dispersion, and twisting is lighter, practical.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; 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.
