Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of flexible bolt with hexagonal indentations threaded end.
Background technology
Bolt is widely used machine components, including bolt head and screw rod, needs and nut screw connection, is used for being fastenedly connected two
The individual part with through hole.This type of attachment claims bolt to connect.As nut is screwed off from bolt, the two zero can be made again
Part separates, therefore bolt connection is belonging to removably connect.Bolt head has turret head, round end, square spigot, countersunk head etc.
Deng, wherein turret head is the most frequently used.General countersunk head is used in requirement and connects the smooth place not having projection, rear surface, because countersunk head can
To be screwed in part；Round end can also be screwed in part, the screwing force of square toes can more greatly, but size is the biggest.
The structure of existing bolt assembly, general as in figure 2 it is shown, include bolt head, be located on bolt head with outer spiral shell
Screw rod that stricture of vagina is cylindrical and the nut being connected with screw rod, there is following defect in such bolt arrangement: bolt is tightened
During, due to stress, nuts and bolt head inevitably occurs that phenomenons such as rocking occur in skidding or screw rod, to such an extent as to needs
By aid, bolt head is fixed, then with aid or manpower by nut screwing clamping, or need will by aid
Nut is fixed, then is tightened by bolt head with aid, can realize the fastening of bolt.The fastening of bolt to be realized,
Fix in bolt one end while of needs, the other end is tightened, if the parts area connected is big, thickness is thick, i.e. the length of threaded rod is relatively
Time long, then need two people to work simultaneously, waste time and energy and labor intensity is big, especially produce in enormous quantities and need bolt to assemble zero
The factory of part, not only production efficiency is low, and cost of human resources is high simultaneously；If after the through hole of connection member put into by bolt, due to
The structure of space or connection member limits, and possibly or cannot be difficult to inserter, thus affect the fastening of bolt, enter at bolt head
And affect work and carry out in order.Additionally, screw rod is linear cylindrical shape, if owing to machining accuracy is inaccurate, needs are caused to connect
Parts through hole the most on the same line, or due to parts appearance surfaces require height, can only at the edge bolt hole of parts,
The screw rod of linear cylindrical shape just cannot be inserted in above connection member, produces the enterprise of parts typically by improving connection member
Machining accuracy or the structure of parts is accurately set, realize the assembling between connection member, thus increase the difficulty of production technology
Degree, improves production cost, reduces production efficiency simultaneously.
Summary of the invention
The deficiency existed for prior art, the present invention provides a kind of flexible spiral shell with hexagonal indentations threaded end
Bolt, this bolt arrange can the hexagonal indentations termination of standing screw and flexible screw rod, just can realize bolt flexibly in screw rod one end
Fastening, time saving and energy saving, bolt hole parts the most on the same line can be met simultaneously and connect, be conducive to improving productivity ratio and
Work efficiency, reduces production cost simultaneously, convenient and practical, is applicable to multiple occasion.
In order to achieve the above object, the technical scheme that the present invention takes:
A kind of flexible bolt with hexagonal indentations threaded end, the screw rod including bolt head, being connected with bolt head and
The nut that screw rod is connected, steel bar and its end that described screw rod is made up of flexible spring steel material are arranged to spiral shell
Stricture of vagina end, this end of thread is provided with and is connected with it and the threaded end of standing screw when bolt is tightened, the described end of thread
The groove of hexagonal structure is offered on head.
As optimal technical scheme, in order to expand connecing of the contact area of connection member and nut, beneficially connection member
Touch and tighten, ensure the firm connection between bolts and nuts simultaneously, effectively prevent loosening, on described screw rod between connection member
Being arranged with the fit sealing part being connected with nut, described fit sealing part is the molectron of spring shim and plain cushion.
Compared with prior art, the invention have the benefit that
1, screw rod is provided with the hexagonal indentations threaded end for fixing it, it is to avoid need one end during conventional bolt fastening
The drawback that fixing, the other end is tightened, just convenient, flexible can realize the fastening of connection member in bolt one end, time saving and energy saving, reduces
Labor intensity, is conducive to improving production efficiency and work efficiency；The screw rod being made up of flexible spring steel material is set, can be real
Existing parts through hole connection the most on the same line, advantageously reduces production cost, and convenient and practical, is applicable to multiple field
Close.
2, the fit sealing part of spring shim peace pad assembly is set, expands the contact area of connection member and nut,
The contact being conducive to connection member is tightened, and ensures the firm connection between bolts and nuts simultaneously, effectively prevent connection member it
Between loosen.
Accompanying drawing explanation
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.

Detailed description of the invention
One specific embodiment of the present invention, a kind of flexible spiral shell with hexagonal indentations threaded end are proposed as shown in Figure 1
Bolt, including bolt head 1, is connected with bolt head 1 and nut 3 that the screw rod 2 of cylindrical structure is connected with screw rod 2, bolt
1 can be arranged to turret head, hemispheric, columned, the present embodiment selects to be arranged to hemispheric, makes bolt head 1
Conveniently being screwed in the parts of connection, the length of screw rod 2 can need rationally to arrange according to difference, and described screw rod 2 is by flexible
The steel bar made of spring steel material and its end be arranged to end of thread 2-1, described screw rod 2 can realize larger angle bending,
But rigidity almost no change, it is ensured that firm between connection member, the top of described end of thread 2-1 be provided be connected with it,
And it is used for the threaded end 4 of standing screw 2 when bolt is tightened, described threaded end 4 offers the groove of hexagonal structure
4-1。
Being arranged with the fit sealing part 5 being connected with nut 3 on described screw rod 2, described fit sealing part 5 is spring shim 5-
1 and the molectron of plain cushion 5-2, fit sealing part 5 can expand the contact area of connection member and nut 3, beneficially connecting portion
The contact of part is tightened, and ensures being firmly connected between screw rod 2 and nut 3 simultaneously, effectively prevents loosening between connection member.
When the present invention uses: screw rod 2 is inserted in the through hole of the two or more parts needing connection, determines bolt head 1
Behind position, plain cushion 5-2, spring shim 5-1, nut 3, threaded end 4 are sequentially sleeved on screw rod 2, with interior hex tool such as
Groove 4-1 put into by interior hexagon screwdriver, thus fixes threaded end 4, and then standing screw 2, and recycling artificial hand is twisted
Or by opening or double offset ring spanner, so that it may convenient, flexible nut 3 is tightened on screw rod 2, can realize connecting logical
Fastening between the parts the most on the same line of hole, time saving and energy saving.
Certainly, the most simply combine accompanying drawing the preferred embodiments of the disclosure to be described in detail, not with this
Limit the practical range of the present invention, the equivalence change that all principles under this invention, structure and structure are made, all should be covered by this
In the protection domain of invention.
