Abstract
The invention discloses an easy-to-screw bolt which comprises a bolt head and a bolt rod. The bolt head is a hexagonal bolt head of which the transverse cross section is shaped like a regular hexagon, and the bottom of the bolt head is fixedly connected with the bolt rod; the bolt rod is of a cylindrical structure, the vertical center axis of the bolt rod and the center axis of the bolt head are on the same straight line, and the outer surface of the bolt rod is provided with a thread; six cylindrical grooves which are same in depth and different in diameters are formed in the six side surfaces of the bolt head respectively, and cross rods matched with the corresponding cylindrical grooves can be embedded into the cylindrical grooves for wrenching and screwing operations. In this way, according to the bolt, multiple wrenching and screwing modes are designed, the selection range is wide, the wrenching and screwing operations of the bolt are more convenient, the practicability is high, and wrenching and screwing are easier.
Description
Technical field
The present invention relates to fixed component field, particularly relate to a kind of easily rotary-screw-type bolt.
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 easily rotary-screw-type bolt, can multiple twisting mode, and range of choice is wide, makes the twisting operation of bolt more convenient, practical, and twisting is lighter.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of easily rotary-screw-type bolt is provided, it is characterized in that, comprising: spiral shell head, screw rod; Described spiral shell head is that its lateral cross section is orthohexagonal hexagonal spiral shell head, and spiral shell head bottom is fixedly connected with described screw rod; Described screw rod is cylindrical structure, the vertical central shaft of screw rod and the central shaft of described spiral shell head are point-blank, on screw rod outer surface, be provided with screw thread, wherein, on six side surfaces of described spiral shell head, be provided with six cylinder grooves that the degree of depth is identical, diameter differs, in described cylinder groove, can embed the cross bar adapting and carry out twisting operation.
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 cylinder groove is all positioned at the central spot of each side.
In a preferred embodiment of the present invention, described cylinder groove does not connect spiral shell head.
The invention has the beneficial effects as follows: bolt design provided by the present invention has multiple twisting mode, and range of choice is wide, make the twisting operation of bolt more convenient, practical, twisting is lighter.
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 easy rotary-screw-type bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1-spiral shell head, 2-screw rod, 3-cylinder groove.
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 easily rotary-screw-type bolt, is characterized in that, comprising: spiral shell head 1, screw rod 2; Described spiral shell head 1 is that its lateral cross section is orthohexagonal hexagonal spiral shell head, and spiral shell head 1 bottom is fixedly connected with described screw rod 2; Described screw rod 2 is cylindrical structure, the vertical central shaft of screw rod 2 and the central shaft of described spiral shell head 1 are point-blank, on screw rod 2 outer surfaces, be provided with screw thread, wherein, on six side surfaces of described spiral shell head 1, be provided with six cylinder grooves 3 that the degree of depth is identical, diameter differs, in described cylinder groove 3, can embed the cross bar adapting and carry out twisting operation.
Described spiral shell head 1, screw rod 2 materials are carbon steel, carbon steel aboundresources, long service life.
Described cylinder groove 3 is all positioned at the central spot of each side.
Described cylinder groove 3 does not connect spiral shell head.
Operation principle of the present invention: the cross bar adapting is filled in cylinder groove 3, utilized lever principle to carry out twisting.
Bolt design provided by the present invention has multiple twisting mode, and range of choice is wide, makes the twisting operation of bolt more convenient, practical, and twisting is lighter.
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.
