Abstract
The invention discloses a slot check bolt comprising a bolt main body, an outer thread and a snap ring groove. The bolt main body is provided with the outer thread, a plane passing through the central axis is a mid-plane, and the snap ring groove is formed in the outer thread in the mid-plane direction. The locking and anti-loosening effects are achieved under the combined action of the snap ring groove and a fastening nut. By means of the method, the slot check bolt has the advantages of being high in reliability, compact in structure, convenient to manufacture, low in cost, long in service life, good in locking performance and detachable, and meanwhile has wide market prospects in the fastener market.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of fluting chek bolt.
Background technique
Bolt is the most frequently used fastening pieces of people, and it is simple in structure, and is easy to use, respond well, is widely used in various occasions.But, in the occasion of some existence vibrations, be used for fastening bolt and often take place to become flexible, cause to connect and throw off, machine failure, even cause security incident, make for this reason and can become very urgent and important by effectively anti-loosening bolt.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of fluting chek bolt, by offering locking groove at the screw thread place, and cooperate block nut to use simultaneously, effective clinch fastener, prevent that fastening piece from getting loose, have that reliability height, compact structure, manufacturing are easy, long service life, advantage such as detachable, cheap in case of necessity, in fastening piece market market prospects are widely arranged simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of fluting chek bolt is provided, comprise: bolt body, outside thread and locking groove, bolt body is provided with outside thread, plane by the medial axis line is midplane, along the midplane direction, outside thread is provided with locking groove.
In a preferred embodiment of the present invention, described outside thread is provided with locking groove, cooperates locking with nut.
In a preferred embodiment of the present invention, described locking groove is along axial direction and isometric with screw thread.
In a preferred embodiment of the present invention, be symmetrical arranged at least 2 locking grooves on the described outside thread, the balance fastening piece is stressed
In a preferred embodiment of the present invention, described bolt body adopts SUS304(0Cr18Ni9) stainless steel.
The invention has the beneficial effects as follows: the present invention slots chek bolt by being arranged on the screw thread place and offering locking groove and being used with corresponding nut, have reliability height, compact structure, easily manufactured, cheap, life-span is long, the stop performance is good, advantage such as detachable has market prospects widely in fastening piece market simultaneously.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the slot structural representation of chek bolt one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, bolt body, 2, outside thread, 3, locking groove.
Embodiment
To the technological scheme in the embodiment of the invention be clearly and completely described below, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiments that obtain under the creative work prerequisite.
See also Fig. 1, the embodiment of the invention comprises:
A kind of fluting chek bolt comprises: bolt body 1, outside thread 2 and locking groove 3, and bolt body 1 is provided with outside thread 3, and the plane by the medial axis line is midplane, and along the midplane direction, outside thread 2 is provided with locking groove 3.
Described outside thread 2 is provided with locking groove 3, cooperates with nut to prevent that the nut rotation is loosening.
Described locking groove 3 is along axial direction and isometric with screw thread 2.Preventing that nut from blocking can't lock.
Be symmetrical arranged at least 2 locking grooves 3 on the described outside thread, the balance fastening piece is stressed, prevents stress damage.
Described bolt body 1 adopts SUS304(0Cr18Ni9) stainless steel.Effectively prevent corrosion, prolong the fastening piece life-span.
Fluting chek bolt working procedure is:
The fixed by nut of screwing on after bolt is installed after nut is tightened, make the nut projection aim at antiratchetting groove, and fastening nut is prevented its counter-rotating.
The slot beneficial effect of chek bolt of the present invention is:
One, by offering antiratchetting groove, prevents screw thread rotation, reach and loosen purpose;
Two, offer antiratchetting groove by symmetry, prevent that the stress effect from damaging;
Three, at screw thread place fluting, easily manufactured, its cost increases very little;
Four, the bolt body material uses SUS304(0Cr18Ni9) stainless steel, prevent the corrosion infringement, have good working life.
Five, than plain bolt, it is good that this invention has an anti-loosing effect, reliability height, compact structure, easily manufactured, cheap, and advantage such as the life-span is long, and is detachable has extensive prospect in fastening piece market.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present invention.
