Abstract
The invention discloses a bolt with a cross screwing groove. The bolt comprises a bolt body, wherein a threaded pillar is arranged at the lower end of the bolt body; a nut is arranged at the upper end of the bolt body; the bottom of the nut is fixedly connected with the threaded pillar; a groove opening is formed in the center on the upper end surface of the nut; the cross screwing groove is formed in the end surface at the bottom of the groove opening, comprises two strip-shaped grooves which are perpendicularly crossed, and is matched with the tip of a screwdriver. According to the invention, the rotational manners of the bolt can be increased, and when the nut edge of the bolt is abraded so much that unscrewing cannot be realized, the bolt can still be unscrewed through the cross screwing groove in the groove opening in the upper end of the nut, so that the screwing choices of the bolt are increased, and the service life is prolonged.
Description
Technical field
The present invention relates to bolt field, particularly relate to a kind of band cross and twist the bolt of groove.
Background technology
Bolt is a kind of machine components, the threaded securing member of cylinder of adapted nut.By a head and bolt class securing member dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole.This type of attachment claims bolt to connect.As nut is screwed off from bolt, the two part can be made again separately, therefore bolt connection is belonging to removably 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.The utilization of visible bolt is extensively.The operation strategies of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods.Boats and ships, vehicle, hydraulic engineering, even chemical experiment are also used bolt.Anyway it is that super many places are useful bolt.The special precision bolt used above such as digital product.DVD, the Micro-bolt that photographing unit, glasses, clock and watch, electronics etc. use；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 there is industry on the earth, then the function of bolt is the most important.But bolt is carried out often by clamping down on nut edge, bolt upper end when rotating dismounting, long-time use rear nut edge to be worn and be difficult to well to be clamped down on fixing so that bolt can not quickly be dismantled, and have impact on bolt and uses.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of band cross and twists the bolt of groove, by increasing capacitance it is possible to increase the rotating manner of bolt, and the nut edge abrasion at bolt cannot be carried out clamping down on when forwarding to, can twist groove by the cross in nut upper recess mouth and rotate.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the bolt that groove twisted in a kind of band cross, including bolt body, described bolt body lower end is provided with threaded post, described bolt body upper end is provided with nut, fix with described threaded post bottom described nut and be connected, described nut upper surface central authorities offer a groove port, offer a cross on described groove port bottom end face and twist groove, described cross is twisted groove and is made up of two brief note connected in stars intersected vertically, and described cross is twisted groove and arranged with screwdriver point of a knife Corresponding matching.
In a preferred embodiment of the present invention, described nut and described threaded post are integral type attachment structure, and described threaded post is vertically arranged and is fixed on described nut bottom end face.
In a preferred embodiment of the present invention, the degree of depth that two the brief note connected in stars offered on groove twisted in described cross is the most identical.
The invention has the beneficial effects as follows: the present invention can increase the rotating manner of bolt, nut edge abrasion at bolt cannot be carried out clamping down on when forwarding to, groove can be twisted by the cross in nut upper recess mouth to rotate, add the selection that bolt rotates, improve service life.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, 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 that bolt one preferred embodiment of groove twisted in band cross of the present invention；
In accompanying drawing, the labelling of each parts is as follows: 1, bolt body；2, threaded post；3, nut；4, groove port；5, groove twisted in cross.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, 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 protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
The bolt of groove twisted in a kind of band cross, 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, fixing with described threaded post 2 bottom described nut 3 and be connected, described nut 3 upper surface central authorities offer 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 made up of two brief note connected in stars intersected vertically, 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 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.
nullThe operation principle of the present invention is for be threaded post 2 in bolt body 1 lower end，Bolt body 1 upper end is provided with nut 3，Fix with threaded post 2 bottom nut 3 and be connected，Nut 3 and threaded post 2 are integral type attachment structure，Threaded post 2 is vertically arranged and is fixed on nut 3 bottom end face，Nut 3 upper surface central authorities offer a groove port 4，Offer a cross on groove port 4 bottom end face and twist groove 5，Cross is twisted groove 5 and is made up of two brief note connected in stars intersected vertically，The degree of depth that two the brief note connected in stars offered on groove 5 twisted in cross is the most identical，Cross is twisted groove 5 and is arranged with screwdriver point of a knife Corresponding matching，Bolt body 1 can rotate by clamping down on nut 3 edge usually，And nut 3 edge abrasion of bolt body 1 cannot be carried out clamping down on forward to time，Groove 5 can be twisted by the cross in nut 3 upper recess mouth 4 to rotate，Add the selection that bolt body 1 rotates，Improve service life.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content 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 the scope of patent protection of the present invention.
