Abstract
The utility model discloses an easily pull and twist type bolt, cast a body structure that forms including spiral shell head, the whole processing of screw rod, the spiral shell head be its transverse section for regular hexagon's hexagonal drive head, its vertical cross -section is " I shape ", the central stringcourse part of spiral shell head is provided with the round rectangular channel, and the first side of spiral shell is connected the screw rod, the screw rod be the cylinder structure, the vertical center pin of screw rod with the center pin of spiral shell head is provided with the screw thread point -blank on the cylinder surface. In this way, the utility model discloses simple structure, novelty, the design of " I shape " spiral shell head most likely for in the spanner can imbed very much the overhead rectangular channel of spiral shell with laminating, the spanner was pulled and is twisted the convenience, and the laminating is firm, and the spanner is landing easily not, and the practicality is strong, has certain economic benefits and market prospect.
Description
Technical field
The utility model relates to fixed component field, particularly relates 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.
Model utility content
The technical problem that the utility model 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 utility model 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 the utility model preferred embodiment, described spiral shell head, the material of screw rod are stainless steel.
In the utility model preferred embodiment, described rectangle groove is positioned at the horizontal center line place of described spiral shell head side surface.
In the utility model preferred embodiment, the width of described rectangle groove is 1/2 of described spiral shell head thickness.
In the utility model preferred embodiment, the groove inner diameter of described rectangle groove is identical with the cross-sectional diameter of described screw rod.
The beneficial effects of the utility model are: the utility model structure 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 utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, 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 utility model 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 utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model is embodiment comprise:
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.
Utility model works principle: the utility model structure is simple, novel, be somebody's turn to do the design of " I shape " spiral shell head, during use, spanner is snugly embedded in the rectangle groove on spiral shell head, spanner twisting is convenient, and firmly, spanner can not landing easily in laminating, practical, there are certain economic benefit and market prospects.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
