Description
Technical field
This utility model relates to bolt field, particularly relates to a kind of band cross and twists the bolt of groove.
Background technology
Bolt is a kind of machine components, the threaded securing member of cylinder of adapted nut.By head and bolt two parts
One class securing member of composition, needs and nut screw connection, for being fastenedly connected two parts with through hole.This type of attachment claims spiral shell
Tether and connect.As nut is screwed off from bolt, the two part can be made again separately, therefore bolt connection is belonging to detachably connect
Connect.Bolt, be can't do without when neutralizing in the middle of commercial production manufacture at daily life, and bolt is also referred to as the rice of industry.Visible
The utilization of bolt is extensively.The operation strategies of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric machine
Tool product.Boats and ships, vehicle, hydraulic engineering, even chemical experiment are also used bolt.Anyway it is that super many places are useful spiral shell
Bolt.The special precision bolt used above such as digital product.DVD, the miniature spiral shell that photographing unit, glasses, clock and watch, electronics etc. use
Bolt；The general bolt of TV, electric product, musical instrument, furniture etc.;Large-sized bolt, nut is then used as engineering, building, bridge；
Traffic tool, aircraft, electric car, automobile etc. then sized by bolt using.Vital task industrially born by bolt, as long as on the earth
There is industry, then the function of bolt is the most important.But bolt rotate dismounting time often by clamping down on bolt upper end nut
Edge is carried out, and long-time use rear nut edge to be worn and is difficult to well to be clamped down on fixing so that bolt can not be quick
Dismounting, have impact on bolt use.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of band cross to twist the bolt of groove, by increasing capacitance it is possible to increase bolt
Rotating manner, the nut edge abrasion at bolt cannot be carried out clamping down on when forwarding to, can be by ten in nut upper recess mouth
Word is twisted groove and is rotated.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of band cross to twist groove
Bolt, including bolt body, described bolt body lower end is provided with threaded post, and described bolt body upper end is provided with nut, described
Fixing with described threaded post bottom nut and be connected, described nut upper surface central authorities offer a groove port, bottom described groove port
Offering a cross on end face and twist groove, described cross is twisted groove and is made up of two brief note connected in stars intersected vertically, described cross
Twist groove to arrange with screwdriver point of a knife Corresponding matching.
In one preferred embodiment of this utility model, described nut and described threaded post are integral type attachment structure, institute
State threaded post to be vertically arranged and be fixed on described nut bottom end face.
In one preferred embodiment of this utility model, the deep of two brief note connected in stars offering on groove twisted in described cross
Spend the most identical.
The beneficial effects of the utility model are: this utility model can increase the rotating manner of bolt, at the nut of bolt
Edge abrasion cannot be carried out clamping down on when forwarding to, can twist groove by the cross in nut upper recess mouth and rotate, add
The selection that bolt rotates, improves service life.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, required in embodiment being described below
Accompanying drawing to be used is briefly described, it should be apparent that, the accompanying drawing in describing below is only realities more of the present utility model
Execute example, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to according to these accompanying drawings
Obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation that bolt one preferred embodiment of groove twisted in this utility model band cross；
In accompanying drawing, the labelling of each parts is as follows: 1, bolt body；2, threaded post；3, nut；4, groove port；5, ten
Groove twisted in word.
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 enforcement in this utility model
Example, 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:
The bolt of groove twisted in a kind of band cross, and including bolt body 1, described bolt body 1 lower end is provided with threaded post 2, described
Bolt body 1 upper end is provided with nut 3, fixes with described threaded post 2 and be connected bottom described nut 3, described nut 3 upper surface central authorities
Offering a groove port 4, described groove port 4 bottom end face offers a cross and twists groove 5, described cross is twisted groove 5 and is hung down by two
The straight brief note connected in star intersected is constituted, and described cross is twisted groove 5 and arranged with screwdriver point of a knife Corresponding matching.
It addition, described nut 3 and described threaded post 2 are integral type attachment structure, described threaded post 2 is vertically arranged and is fixed on
On described nut 3 bottom end face.
It addition, the degree of depth that two the brief note connected in stars offered on groove 5 twisted in described cross is the most identical.
Operation principle of the present utility model is for be threaded post 2 in bolt body 1 lower end, and bolt body 1 upper end is provided with spiral shell
Cap 3, fixes with threaded post 2 bottom nut 3 and is connected, and nut 3 and threaded post 2 are integral type attachment structure, and threaded post 2 is vertically arranged
Being fixed on nut 3 bottom end face, nut 3 upper surface central authorities offer a groove port 4, and groove port 4 bottom end face offers
Groove 5 twisted in one cross, and cross is twisted groove 5 and is made up of two brief note connected in stars intersected vertically, and two offered on groove 5 twisted in cross
The degree of depth of brief note connected in star is the most identical, and cross is twisted groove 5 and arranged with screwdriver point of a knife Corresponding matching, and bolt body 1 can lead to usually
Cross and clamp down on nut 3 edge and rotate, and nut 3 edge abrasion of bolt body 1 cannot be carried out clamping down on forward to time, Ke Yitong
Cross the cross in nut 3 upper recess mouth 4 to twist groove 5 and rotate, add the selection that bolt body 1 rotates, improve use
Life-span.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
