Abstract
The utility model discloses a but wrong bolt is pulled to double -end, 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 vertical center pin with the center pin of spiral shell head point -blank, the screw rod includes screw thread portion and pulls the portion of twisting two parts, screw thread portion set up screwed cylinder structure for the surface, pull the portion of twisting connect screw troops under one's command position in the screw rod bottom, it is regular hexagon's hexagonal -prism structure for the cross section to pull the portion of twisting, screw portion with pull the portion of twisting and form a body structure. In this way, the utility model provides a bolt two all can be pulled and twisted the operation, pulls in wrong at luo touchu, utilizes the portion of twisting of pulling of screw rod bottom assist the wrong work of pulling, makes to pull and twists the atress dispersion, pulls wrongly lighter, and the practicality is strong.
Description
Technical field
This utility model relates to fixing member arts, particularly relate to a kind of can the bolt of double end twisting.
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 mainly solving the technical problems that provide a kind of can the bolt of double end twisting, it is possible to carry out double end twisting operation, while carrying out twisting at screw head, the twisting portion bottom screw rod is utilized to carry out assisting twisting work, making twisting force dispersion, twisting is lighter, practical.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of can the bolt of double end twisting, it is characterized in that, including: screw head, screw rod, described screw head be its lateral cross section be orthohexagonal hexagonal screw head, the screw rod described in connecting is fixed bottom screw head, the vertical central shaft of described screw rod is with the central shaft of described screw head point-blank, screw rod includes threaded portion and twisting portion two parts, described threaded portion is that outer surface arranges threaded cylindrical structure, described twisting portion is connected to bottom the screw rod that is positioned at below threaded portion, twisting portion be cross section be orthohexagonal six prism structures, threaded portion forms integrative-structure with twisting portion.
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 twisting portion is located on the same line with the vertical central axis of threaded portion.
In one preferred embodiment of this utility model, the regular hexagonal cross section in described twisting portion is connected to the circular cross-section of threaded portion in being.
In one preferred embodiment of this utility model, the height in described twisting portion is equal to the height of screw head.
The beneficial effects of the utility model are: bolt two provided by the utility model all can carry out twisting operation, while carrying out twisting at screw head, utilize the twisting portion bottom screw rod to carry out assisting twisting work, make twisting force dispersion, twisting is lighter, practical.
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 that this utility model is a kind of can the structural representation of bolt one preferred embodiment of double end twisting；
In accompanying drawing, the labelling of each parts is as follows: 1-screw head, 2-screw rod, 21-threaded portion, 22-twisting portion.
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 can the bolt of double end twisting, it is characterized in that, including: screw head 1, screw rod 2, described screw head 1 be its lateral cross section be orthohexagonal hexagonal screw head, the screw rod 2 described in connecting is fixed bottom screw head 1, the central shaft of the vertical central shaft of described screw rod 2 and described screw head 1 is point-blank, screw rod 2 includes threaded portion 21 and twisting portion 22 two parts, described threaded portion 21 arranges threaded cylindrical structure for outer surface, described twisting portion 22 is connected to bottom the screw rod 2 that is positioned at below threaded portion 21, twisting portion 22 is orthohexagonal six prism structures for cross section, threaded portion 21 and twisting portion 22 form integrative-structure.
Described screw head 1, screw rod 2 material are carbon steel.
Described twisting portion 22 is located on the same line with the vertical central axis of threaded portion 21.
The regular hexagonal cross section in described twisting portion 22 is connected to the circular cross-section of threaded portion 21 in being, do not affect the normal upper of bolt and use.
The height in described twisting portion 22 is equal to the height of screw head 1.
Bolt two provided by the utility model all can carry out twisting operation, while carrying out twisting, utilizes the twisting portion bottom screw rod to carry out assisting twisting work, makes twisting force dispersion at screw head, and twisting is lighter, practical.
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.
