Abstract

The utility model discloses a yi xuan twists type bolt, including spiral shell head, screw rod, the spiral shell head be its transverse section for regular hexagon's hexagonal drive head, spiral shell head bottom fixed connection 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 screw rod surface, wherein six side surfaces of spiral shell head on all be provided with six cylinder recesses that the degree of depth is the same, the diameter differs, the cylinder recess in the horizontal pole that suits of insertible pull and twist the operation. In this way, the utility model provides a bolt design has the multiple wrong mode of pulling, and the choice is wide for it is more convenient that the operation is twisted to the pulling of bolt, and the practicality is strong, pull twist lighter.

Description

A kind of easily rotary-screw-type bolt
Technical field
This utility model relates to fixing member arts, particularly relates to a kind of easily rotary-screw-type bolt.
Background technology
Bolt is the one of machine components, the threaded securing member of cylinder of adapted nut, by a head and screw rod class securing member dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, at present, bolt arrangement on market is similar to, mostly being solid construction, twisting mode is all screw head to be clamped by spanner, then screws, twisting mode is single, and twisting is very painstaking, spanner stress point in screw head is few, operates the lightest.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of easily rotary-screw-type bolt, it is possible to multiple twisting mode, and the range of choice is wide so that the twisting operation of bolt is more convenient, and practical, twisting is lighter.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of easily rotary-screw-type bolt, it is characterised in that including: screw head, screw rod;Described screw head be its lateral cross section be orthohexagonal hexagonal screw head, bottom screw head fixing connect described in screw rod;Described screw rod is cylindrical structure, the vertical central shaft of screw rod is with the central shaft of described screw head point-blank, it is provided with screw thread on screw rod outer surface, wherein, six side surfaces of described screw head are provided with the cylinder groove that six degree of depth are identical, diameter differs, the cross bar adapted can be embedded in described cylinder groove to carry out twisting operation.
In one preferred embodiment of this utility model, described screw head, screw rod material are carbon steel.
In one preferred embodiment of this utility model, described cylinder groove is respectively positioned on the central spot of each side.
In one preferred embodiment of this utility model, the described the most through screw head of cylinder groove.
The beneficial effects of the utility model are: bolt provided by the utility model is designed with multiple twisting mode, and the range of choice is wide so that the twisting operation of bolt is more convenient, and practical, twisting is lighter.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model a kind of easy rotary-screw-type bolt one preferred embodiment;
In accompanying drawing, the labelling of each parts is as follows: 1-screw head, 2-screw rod, 3-cylinder groove.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of easily rotary-screw-type bolt, it is characterised in that including: screw head 1, screw rod 2;Described screw head 1 be its lateral cross section be orthohexagonal hexagonal screw head, bottom screw head 1 fixing connect described in screw rod 2;Described screw rod 2 is cylindrical structure, the central shaft of the vertical central shaft of screw rod 2 and described screw head 1 is point-blank, it is provided with screw thread on screw rod 2 outer surface, wherein, six side surfaces of described screw head 1 are provided with the cylinder groove 3 that six degree of depth are identical, diameter differs, in described cylinder groove 3, the cross bar adapted can be embedded to carry out twisting operation.
Described screw head 1, screw rod 2 material are carbon steel, and carbon steel aboundresources, service life is long.
Described cylinder groove 3 is respectively positioned on the central spot of each side.
The described the most through screw head of cylinder groove 3.
Utility model works principle: filled in cylinder groove 3 by the cross bar adapted, utilizes lever principle to carry out twisting.
Bolt provided by the utility model is designed with multiple twisting mode, and the range of choice is wide so that the twisting operation of bolt is more convenient, and practical, twisting is lighter.
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 equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
