Abstract
The utility model discloses a flexible bolt with hexagonal groove threaded end, include bolt head, the screw rod that links to each other with the bolt head, cooperate the nut of being connected with the screw rod, the thread end is set to by billet and its tip that flexible spring steel material made to the screw rod, be equipped with on this thread end rather than the cooperation connect, when it is used for bolt tightening clamping screw's threaded end, the last recess of seting up and being the hexagon structure of threaded end. The setting of this bolt is equipped with the hexagon threaded end who is used for clamping screw, needs the drawback that one end is fixed, one end is screwed up when avoiding traditional bolt -up, just can make things convenient for the nimble fastening that realizes adapting unit in bolt one end, and labour saving and time saving reduces intensity of labour, is favorable to improving production efficiency and work efficiency, the not connection on same straight line of parts through -hole can be realized to the screw rod that the setting was made by flexible spring steel material, is favorable to reduction in production cost, and convenient and practical, and is applicable in multiple occasion, is worth extensively promoting.
Description
Technical field
This utility model is related to a kind of bolt, and in particular 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, is needed and nut screw connection, for being fastenedly connected two
The individual part with through hole.This type of attachment claims bolt connection.As nut is screwed off from bolt, can make again the two zero
Part separates, therefore bolt connection is belonging to be detachably connected.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 and requires after connection that surface is smooth and do not have where projection, because countersunk head can
In to be screwed to part；Round end can also be screwed in part, and the screwing force of square toes can more greatly, but size is very big.
The structure of existing bolt assembly, it is general as shown in Fig. 2 including bolt head, on bolt head with outer spiral shell
There is following defect in the cylindrical screw rod of stricture of vagina and the nut being connected with screw rod, such bolt arrangement：Bolt is tightened
During, due to stress, inevitably there are the phenomenons such as skid or rocking occurs in screw rod in nuts and bolt head, so that needing
Bolt head is fixed by aid, then with aid or manpower by nut screwing clamping, or needs will by aid
Nut is fixed, then is tightened bolt head with aid, can realize the fastening of bolt.The fastening of bolt is namely realized,
Need to fix in bolt one end simultaneously, the other end is tightened, if the part area of connection is big, thickness is thick, i.e., the length of threaded rod compared with
When long, then need two people to work simultaneously, waste time and energy and high labor intensive, especially producing in enormous quantities needs bolt assembling zero
The factory of part, not only production efficiency is low, while cost of human resources is high；If bolt is put into after the through hole of connection member, due to
The structure of space or connection member is limited, and possibly inserter or cannot be difficult at bolt head, so as to affect the fastening of bolt, is entered
And affect work to carry out in order.Additionally, screw rod is linear cylindrical shape, if because machining accuracy is inaccurate, resulting in the need for what is connected
Part through hole not on the same line, or because part appearance surfaces have high demands, can only in the edge bolt hole of part,
The screw rod of linear cylindrical shape just cannot be inserted in the connection member of the above, produce the enterprise of part typically by improving connection member
Machining accuracy or accurate set parts structure realizing the assembling between connection member, so as to increase the difficulty of production technology
Degree, improves production cost, while reducing production efficiency.
Utility model content
In view of the shortcomings of the prior art, this utility model provides a kind of flexibility with hexagonal indentations threaded end
Bolt, this bolt arrange can standing screw hexagonal indentations termination and flexible screw rod, can flexibly realize spiral shell in screw rod one end
The fastening of bolt, it is time saving and energy saving, while bolt hole part connection not on the same line can be met, be conducive to improving productivity ratio
And work efficiency, while production cost is reduced, and it is convenient and practical, it is applicable to various occasions.
In order to achieve the above object, the technical scheme that this utility model is taken：
A kind of flexible bolt with hexagonal indentations threaded end, including the screw rod that is connected with bolt head of bolt head and
The nut that screw rod is connected, the screw rod is the steel bar and its end is arranged to spiral shell by made by flexible spring steel material
Stricture of vagina end, the end of thread is provided with the threaded end of standing screw when being connected with it and tightening for bolt, the end of thread
The groove of hexagonal structure is offered on head.
As optimal technical scheme, in order to expand the contact area of connection member and nut, be conducive to connecing for connection member
Touch and tighten, while ensureing the firm connection between bolts and nuts, the loosening between connection member is effectively prevented, on the screw rod
The fit sealing part being connected with nut is arranged with, the fit sealing part is the molectron of spring shim and plain cushion.
Compared with prior art, this utility model has the advantage that：
1st, screw rod is provided with the hexagonal indentations threaded end for fixing it, it is to avoid conventional bolt needs one end when fastening
The drawbacks of fixed, other end is tightened, in bolt one end the fastening of connection member convenient, flexible can be realized, time saving and energy saving, reduced
Labor intensity, is conducive to improve production efficiency and work efficiency；The screw rod by made by flexible spring steel material is set, can be real
The connection not on the same line of existing part through hole, advantageously reduces production cost, and convenient and practical, is applicable to various fields
Close.
The 2nd, the fit sealing part of spring shim peace pad assembly is set, expands the contact area of connection member and nut,
The contact for being conducive to connection member is tightened, at the same ensure bolts and nuts between firm connection, effectively prevent connection member it
Between loosening.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is described in further detail with specific embodiment.
Fig. 1 is structural representation of the present utility model；
The structural representation of the existing bolts of Fig. 2；
Drawing reference numeral：1st, bolt head, 2, screw rod, 2-1, the end of thread, 3, nut, 4, threaded end, 4-1, groove, 5, fastening
