Abstract
The invention discloses a bolt assembly which comprises a bolt and a nut. The bolt comprises a head portion and a screw composed of a polished rod section and a threaded section; the head portion of the bolt is circular and the opposite sides of the lower surface of the head portion are respectively provided with a protrusion portion protruding outwards; the outer side face of the nut is hexagonal and the inner diameter of the inner side face of the nut is equal to the outer diameter of the head portion of the bolt; grooves are further formed in the inner side face of the nut so that the grooves can be matched with the protrusion portions of the head portion of the bolt, and therefore the bolt can be rotated through rotation of the nut. According to the bolt assembly, when the bolt is screwed, only the corresponding nut can be used as a connecting piece for indirectly screwing the bolt, so that once the bolt is fastened, the bolt is difficult to be separated from a connecting through hole of the bolt without the assistance of the corresponding nut, the good protection function is achieved, and therefore a fastened part is prevented from being stolen by a thief.
Description
Technical field
The present invention relates to a kind of fastening piece, be a kind of bolt assembly with being specifically related to.
Background technique
Bolt is one of a kind of common fastening piece, and it is for being fastenedly connected two parts with through hole.It is all generally to take the head of bolt to realize bolt is screwed to site of action as site of action for the bolt of using at present in the process of use, otherwise the reverse rotation bolt head just can easily spin off bolt from the through hole of connection.Wherein concerning those public use and parts that loss by theft rate is higher, while coming it fixedly with bolt, it is requiring to use the bolt stationary device to one-time fix, and with prevention lawless person's pilferage, common used like this bolt just can't meet above-mentioned requirement.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of bolt assembly.
Technical solution of the present invention is achieved in that a kind of bolt assembly, comprises bolt and nut, and described bolt comprises head and the screw rod to downward-extension from the head bottom surface; Described screw rod comprises the polished rod section that extends to form from head downwards, extends to form downwards and length is greater than the thread section of polished rod section from described polished rod section; The head of described bolt is arranged to circle, and is respectively arranged with outwards outstanding protuberance on the opposite side of its lower surface; The outer side surface of described nut is arranged to Hexagon, and the inner diameter of inner side surface equates with the outer diameter of bolt head; Also be provided with groove on the inner side surface of described nut, in order to match with the protuberance of bolt head, and then realization reaches the effect of rotating bolt by rotary nut.
Further, the outer side surface of described protuberance is arranged to circular-arc.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described bolt assembly of the present invention program is in the process of using, because the head of bolt is arranged to be provided with the round structure of protuberance, such bolt is in the process that it is screwed, can only borrow group in nut corresponding thereto as the switching thing, indirectly bolt is carried out to screw action, such bolt be not difficult to again it is being broken away from and coming from the connecting through hole of effect by corresponding nut after fastening getting well, can play good protective action, be stolen by the lawless person with the parts that prevent its fastening effect; What between bolt and nut, its outer surface of interactional protuberance was circular arc simultaneously, further improved the difficulty of not by nut the time, bolt being rotated.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The exploded view that accompanying drawing 1 is bolt assembly of the present invention;
Wherein: 1, bolt; 2, nut; 3, head; 4, screw rod; 5, protuberance; 6, groove.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of bolt assembly of the present invention, comprises bolt 1 and nut 2, and described bolt 1 comprises head 3 and the screw rod 4 to downward-extension from head 3 bottom surfaces; Described screw rod 4 comprises the polished rod section that extends to form from head 3 downwards, extends to form downwards and length is greater than the thread section of polished rod section from described polished rod section; The head 3 of described bolt 1 is arranged to circle, and is respectively arranged with outwards outstanding protuberance 5 on the opposite side of its lower surface; The outer side surface of described nut 2 is arranged to Hexagon, and the inner diameter of inner side surface equates with the outer diameter of bolt 1 head 3; Also be provided with groove 6 on the inner side surface of described nut 2, in order to match with the protuberance 5 of bolt 1 head 3, and then realization reaches the effect of rotating bolt 1 by rotary nut 2.
The outer side surface of wherein said protuberance 5 is arranged to circular-arc.
Bolt assembly of the present invention is in the process of using, because the head 3 of bolt 1 is arranged to be provided with the round structure of protuberance 5, such bolt 1 is in the process that it is screwed, can only borrow group in nut 2 conduct switching things corresponding thereto, and by coordinating indirectly between groove 6 and protuberance 5, bolt 1 is carried out to screw action, such bolt 1 be not difficult to again it is being broken away from and coming from the connecting through hole of effect by corresponding nut 2 after fastening getting well, can play good protective action, with the parts that prevent its fastening effect, by the lawless person, stolen, what between bolt 1 and nut 2, interactional protuberance 5 its outer surfaces were circular arc simultaneously, further improved the difficulty of not by nut 2 time, bolt 1 being rotated.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a bolt assembly, comprise bolt and nut, and described bolt comprises head and the screw rod to downward-extension from the head bottom surface; Described screw rod comprises the polished rod section that extends to form from head downwards, extends to form downwards and length is greater than the thread section of polished rod section from described polished rod section; It is characterized in that: the head of described bolt is arranged to circle, and is respectively arranged with outwards outstanding protuberance on the opposite side of its lower surface; The outer side surface of described nut is arranged to Hexagon, and the inner diameter of inner side surface equates with the outer diameter of bolt head; Also be provided with groove on the inner side surface of described nut, in order to match with the protuberance of bolt head, and then realization reaches the effect of rotating bolt by rotary nut.
