Abstract
The utility model discloses a square screw of a word, including spiral shell head, shank of screw, spiral shell head and shank of screw structure as an organic whole, the whole cast forms, the spiral shell head be square spatial structure, the thickness at spiral shell head outside edge therefrom evenly steadilys decrease in the mind -set outside, the overhead limit of spiral shell face be provided with a style of calligraphy recess, spiral shell head downwardly extending direction of connection the shank of screw, shank of screw top be the cylinder structure, the tail end is the toper, is provided with the screw thread on the shank of screw surface, wherein, the edge axle of spiral shell head can imbed just a style of calligraphy recess in. In this way, the utility model discloses simple structure, the novelty is set spiral shell head marginal portion can imbed to and is pulled wrong structure in the straight line groove for wrong instrument can simple and easy be pulled as one kind to this kind of screw itself, and is convenient, swift, practical, can operate each other between the screw and need not in addition the area and pull wrong instrument, has certain economic benefits and market prospect.
Description
Technical field
The utility model relates to fixed component field, particularly relates to an a kind of word square screw.
Background technique
Screw is a kind of fastening piece conventional in daily life and industry, the spiral shell head diameter of screw is comparatively large, generally rounded or etc. Hexagon, at present, for prior art, when screw is operated, usually need to allow instrument carry out rotation screw as screwdriver or spanner, there is no instrument at one's side if run into, usually feel simply helpless, so, need to arrange a kind of easy screwing tool at screw self, strengthen the functional of screw.
Model utility content
The technical problem that the utility model mainly solves is to provide an a kind of word square screw, and screw itself can be made to use as a kind of easy twisting instrument, convenient and swift, in case of need.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide an a kind of word square screw, it is characterized in that, comprise: spiral shell head, screw rod, described spiral shell head and screw rod are structure as a whole, cast inblock forms, described spiral shell head is square stereochemical structure, the thickness of spiral shell head outer ledge evenly successively decreases laterally from center, described face, spiral shell head top is provided with yi word pattern groove, screw rod described in the downward bearing of trend of described spiral shell head connects, described screw rod top is divided into cylindrical structure, tail end is tapered, screw rod outer surface is provided with screw thread, wherein, the edge axle of described spiral shell head can embed in described yi word pattern groove just.
In the utility model preferred embodiment, described spiral shell head, the making material of screw rod are stainless steel or carbon steel.
In the utility model preferred embodiment, the lateral section of described spiral shell head edge is trapezium structure.
In the utility model preferred embodiment, the thickness that descends most of described spiral shell head edge is less than the width of described yi word pattern groove.
In the utility model preferred embodiment, described yi word pattern groove is positioned on the diagonal of described spiral shell head, and length is more than or equal to the length of side of spiral shell head, and the degree of depth is 2-3mm.
The beneficial effects of the utility model are: the utility model structure is simple, novel, spiral shell head edge part is arranged to embed the structure of carrying out twisting in straight groove, make this kind of screw itself can as the easy twisting instrument of one, convenient, fast, practical, get final product mutual operation between screw and without the need to being separately with twisting instrument, have 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 word square screw one preferred embodiment of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1-spiral shell head, 2-screw rod, 3-yi word pattern 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:
An a kind of word square screw, it is characterized in that, comprise: spiral shell head 1, screw rod 2, described spiral shell head 1 is structure as a whole with screw rod 2, cast inblock forms, described spiral shell head 1 is square stereochemical structure, the thickness of spiral shell head 1 outer ledge evenly successively decreases laterally from center, described face, spiral shell head 1 top is provided with yi word pattern groove 3, screw rod 2 described in the bearing of trend connection downwards of described spiral shell head 1, described screw rod 2 top is divided into cylindrical structure, and tail end is tapered, and screw rod 2 outer surface is provided with screw thread; Wherein, the edge axle of described spiral shell head 1 can embed in described yi word pattern groove 3 just.
Be different from prior art.
In another embodiment, described spiral shell head 1, the making material of screw rod 2 are stainless steel or carbon steel, rich material resources, durable, hardness is large.
In another embodiment, the lateral section at described spiral shell head 1 edge is trapezium structure.
In another embodiment, the thickness that descends most at described spiral shell head 1 edge is less than the width of described yi word pattern groove 3, and the edge section of the spiral shell head of screw can effectively be embedded in described yi word pattern groove.
In another embodiment, described yi word pattern groove 3 is positioned on the diagonal of described spiral shell head 1, and length is more than or equal to the length of side of spiral shell head 1, and the degree of depth is 2-3mm.
The utility model structure is simple, novel, spiral shell head edge part is arranged to embed the structure of carrying out twisting in straight groove, make this kind of screw itself can as the easy twisting instrument of one, during use, torquing operations can be carried out by the screw of this kind of model to another identical screw, convenient, fast, practical, get final product mutual operation between screw and without the need to being separately with twisting instrument, have 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.
