Abstract
The invention discloses a bolt easy to pull and screw. The bolt comprises an integral structure formed by machining and casting a bolt head and a threaded rod as a whole. The bolt head is a hexagonal screw head with the orthohexagonal cross section. The vertical section of the bolt head is in an H shape. A circle of rectangular groove is formed in the center waistline part of the bolt head. One side of the bolt head is connected with the threaded rod which is of a cylinder structure. The vertical central axis of the threaded rod and the central axis of the bolt head are in the same straight line. A thread is arranged on the outer surface of the cylinder. By means of the mode, the bolt is simple and novel in structure; due to the design of the H-shaped bolt head, a wrench can be embedded in the rectangular groove in the bolt head in a quite fit mode, the wrench can conveniently conduct pulling and screwing and is firm in attachment, the wrench is not prone to slipping and is high in practicability, and certain economic benefits and market prospects are achieved.
Description
Technical field
The present invention relates to fixed component field, particularly relate to a kind of easily twisting type bolt.
Background technique
Bolt is the one of mechanical parts; the cylindrical threaded fastening piece of adapted nut; by head and a screw rod class fastening piece dimerous; need and nut screw connection; for being fastenedly connected two parts with through hole; at present; bolt on market is combined by spiral shell head and screw rod two-part mostly; function singleness; in the prior art, the spiral shell head design of existing bolt is mostly stereotyped, when using spanner to carry out twisting; usually can cause spanner landing because of spiral shell head does not have draw-in groove to block spanner, have some limitations.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of easily twisting type bolt, and spanner of can fitting, is convenient to twisting, not landing.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of easily twisting type bolt, it is characterized in that, comprising: the integrative-structure of spiral shell head, screw rod overall processing casting; Described spiral shell head is its lateral cross section is orthohexagonal hexagonal spiral shell head, and its vertical cross-section is in " I shape ", and the center stringcourse part of described spiral shell head is provided with a circle rectangle groove, the screw rod described in the first side of spiral shell connects; Described screw rod is cylindrical structure, and the vertical central shaft of screw rod and the central shaft of described spiral shell head, cartridge outer surface are provided with screw thread point-blank.
In a preferred embodiment of the present invention, described spiral shell head, the material of screw rod are stainless steel.
In a preferred embodiment of the present invention, described rectangle groove is positioned at the horizontal center line place of described spiral shell head side surface.
In a preferred embodiment of the present invention, the width of described rectangle groove is 1/2 of described spiral shell head thickness.
In a preferred embodiment of the present invention, the groove inner diameter of described rectangle groove is identical with the cross-sectional diameter of described screw rod.
The invention has the beneficial effects as follows: structure of the present invention is simple, novel, be somebody's turn to do the design of " I shape " spiral shell head, in the rectangle groove that spanner can very snugly be embedded on spiral shell head, spanner twisting is convenient, laminating firmly, spanner can not landing easily, practical, has certain economic benefit and market prospects.
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 a kind of easy twisting type bolt one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1-spiral shell head, 2-screw rod, 3-rectangle groove.
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 easily twisting type bolt, is characterized in that, comprising: the integrative-structure of spiral shell head 1, screw rod 2 overall processing casting; Described spiral shell head 1 is its lateral cross section is orthohexagonal hexagonal spiral shell head, and its vertical cross-section is in " I shape ", and the center stringcourse part of described spiral shell head 1 is provided with a circle rectangle groove 3, the screw rod 2 described in spiral shell head 1 side connects; Described screw rod 2 is cylindrical structure, and the vertical central shaft of screw rod 2 and the central shaft of described spiral shell head 1, cartridge outer surface are provided with screw thread point-blank.
Be different from prior art.
In another embodiment, described spiral shell head 1, the material of screw rod 2 are stainless steel, and stainless steel is corrosion-resistant, wear-resistant, long service life.
In another embodiment, described rectangle groove 3 is positioned at the horizontal center line place of described spiral shell head side surface, symmetrical configuration.
In another embodiment, the width of described rectangle groove 3 is 1/2 of described spiral shell head thickness.
In another embodiment, the groove inner diameter of described rectangle groove 3 is identical with the cross-sectional diameter of described screw rod.
Working principle of the present invention: structure of the present invention is simple, novel, is somebody's turn to do the design of " I shape " spiral shell head, during use, snugly embedded by spanner in the rectangle groove on spiral shell head, spanner twisting is convenient, and laminating firmly, spanner can not landing easily, practical, has certain economic benefit and market prospects.
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.
