Abstract
The invention discloses an elastic locking nut. The elastic locking nut comprises a nut body, inner threads, isolating grooves, cut-off grooves and locking elastic pieces. The inner threads are arranged inside the nut body, the isolating grooves are formed in the middle of the nut and perpendicular to the central axis of the nut, and the cut-off grooves cut off the upper portion of the nut body to form the locking elastic pieces. Through the method, the elastic locking nut has the advantages of being high in reliability, convenient to install, compact in structure, good in loosening prevention effect, long in service life, low in cost and the like, and has broad market prospects in the market of fastening pieces.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of elasticity block nut.
Background technique
Nut 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 nut 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 nut.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of elasticity block nut, mode by shell fragment wedge shape projection and bolt slot dieback reaches anti-loosing effect, reliability height, easy for installation, compact structure, good, the long service life of anti-loosing effect, advantage such as cheap has market prospects widely in fastening piece market.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of elasticity block nut is provided, comprise: nut body, internal thread, isolation channel, cut off groove and stop shell fragment, nut body is provided with internal thread, the nut intermediate vertical is provided with isolation channel in central axis, cuts off groove and cut out the stop shell fragment above nut body.
In a preferred embodiment of the present invention, described isolation channel is perpendicular to the nut central shaft.
In a preferred embodiment of the present invention, described stop shell fragment has 2.
In a preferred embodiment of the present invention, stop shell fragment end is provided with the wedge shaped stop block
In a preferred embodiment of the present invention, nut body adopts SUS304(0Cr18Ni9) the stainless steel manufacturing.
The invention has the beneficial effects as follows: elasticity block nut of the present invention is by spring sheet block stud bolt draw-in groove, prevent that the nut counter-rotating from making fastening piece loosening, have reliability height, easy for installation, compact structure, good, the long service life of anti-loosing effect, advantage such as cheap has market prospects widely in fastening piece market.
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 structural representation of elasticity block nut one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, nut body, 2, internal thread, 3, isolation channel, 4, cut off groove, 5, the stop shell fragment.
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 elasticity block nut, comprise: nut body 1, internal thread 2, isolation channel 3, cut off groove 4 and stop shell fragment 5, nut body 1 is provided with internal thread 2, and the nut intermediate vertical is provided with isolation channel 3 in central axis, cuts off groove 4 and cut out stop shell fragment 5 above nut body.
Described isolation channel 3 is perpendicular to the nut central shaft.Prevent that screw thread from disturbing the work of stop shell fragment
Described stop shell fragment 5 has 2, and the balance nut is stressed, prevents that the stop shell fragment from damaging.
Described stop shell fragment 5 ends are provided with the wedge shaped stop block, make things convenient for bolt to be screwed into, and prevent that effectively the disengagement of nut shell fragment is loosening, guarantee fastening anti-loosing effect.
The working procedure of elasticity block nut is:
After bolt is good and sound, nut is screwed into, because the existence of the terminal wedge-shaped structure of shell fragment, make that when being screwed into shell fragment flicks at the draw-in groove place, do not hinder nut normally to be screwed into, after nut is tightened, the wedge shape projection of shell fragment snaps in draw-in groove and reverse dieback, prevents the nut reverse rotation, guarantees the nut anti-loosing effect.
The beneficial effect of elasticity block nut of the present invention is:
One, by shell fragment and wedge shape projection are set, make things convenient for nut to be screwed into and prevent that effectively fastening piece from getting loose;
Two, process shell fragment by the mode of fluting, cheap for manufacturing cost;
Three, adopt SUS304(0Cr18Ni9) the stainless steel manufacturing, favorable mechanical characteristic and working life are arranged;
Four, compare nut, the elasticity block nut has simple in structure, and reliability height, easy for installation, advantage such as anti-loosing effect good, long service life, and is cheap have market prospects widely 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.
