Abstract
The invention discloses an elastic locking bolt which comprises a bolt body, outer threads, a through hole, inner threads and a locking cover. The outer threads are arranged on the bolt body, the through hole is formed in the bolt along the central axis, the converse inner threads are arranged inside the through hole, and the inner threads are used for fixing the locking cover. Through the method, the elastic locking bolt 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 hollow 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 hollow bolt, by the mode of reverse internal thread and tight locking closure is set, prevent that nut from reversing, reach tight lock purpose, 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.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: hollow bolt is provided, comprise: bolt body, outside thread, through hole, internal thread and tightening cover, bolt body is provided with outside thread, bolt is provided with through hole along central axis, be provided with reverse internal thread in the through hole, internal thread is used for the fixing and locking lid.
In a preferred embodiment of the present invention, described internal thread length and outside thread are isometric.
In a preferred embodiment of the present invention, in the middle of being stamped, described locking is provided with screw column.
In a preferred embodiment of the present invention, described tightening cover outer ring internal diameter is that 1.1D(D is the diameter of bolt).
In a preferred embodiment of the present invention, bolt body adopts SUS304(0Cr18Ni9) the stainless steel manufacturing.
The invention has the beneficial effects as follows: hollow bolt of the present invention is by arranging the mode of reverse internal thread and tight locking closure, prevent that nut from reversing, reach tight lock purpose, 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 hollow bolt one preferred embodiment of the present invention;
Fig. 2 is tight locking closure structural representation;
Fig. 3 is the present invention
The mark of each parts is as follows in the accompanying drawing: 1, bolt body, 2, outside thread, 3, through hole, 4, internal thread, 5, tight locking closure, 6, screw column, 7, go up material, 8, material down, 9, nut, 10, spring washer, 11, pad.
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 to Fig. 3, the embodiment of the invention comprises:
A kind of hollow bolt, comprise: bolt body 1, outside thread 2, through hole 3, internal thread 4 and tightening cover 5, bolt body 1 is provided with outside thread 2, and bolt is provided with through hole 3 along central axis, be provided with reverse internal thread 4 in the through hole 3, internal thread 4 is used for fixing and locking lid 5.
Described internal thread 4 length and outside thread 2 are isometric, have good mounting characteristics.
Be provided with screw column 6 in the middle of described tightening cover 5 has, can be fit in the through hole, and make tight locking closure dieback nut.
Described tightening cover 5 outer ring internal diameters are that 1.1D(D is the diameter of bolt), prevent that tight locking closure can't be screwed into
Bolt body adopts SUS304(0Cr18Ni9) the stainless steel manufacturing, have better elastic and rustless property, long service life.
The working procedure of hollow bolt is:
After bolt is good and sound, nut is tightened, and tight locking closure is installed, it is tightened, and the dieback nut, because bolt outside thread and internal thread are reverse, make when becoming flexible, the motion of nut and friction make tight locking closure inwardly be screwed into, and SLIDING NUTS is further loosening, guarantees the screw retention effect.
The beneficial effect of elasticity dogbolt of the present invention is:
One, by through hole is set, internal thread and screw column make things convenient for nut to be screwed into and prevent that effectively fastening piece from getting loose;
Two, the mode that oppositely arranges by internal and external threads stops the nut counter-rotating;
Three, adopt SUS304(0Cr18Ni9) the stainless steel manufacturing, favorable mechanical characteristic and working life are arranged;
Four, compare plain bolt, hollow bolt has simple in structure, the reliability height, easy for installation, anti-loosing effect good, in light weight, long service life, advantage such as cheap has 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.
