Description

It is a kind of easily to twist flexibility bolt with hexagonal indentations threaded end
Technical field
This utility model is related to a kind of bolt, and in particular to a kind of easily to twist flexibility spiral shell with hexagonal indentations threaded end Bolt.
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, and nut is usually hexagonal shape and length Degree is shorter, and lifting surface area is little, and handss can tingle when manpower is tightened, and also needs very great strength by aid;Or need Nut is fixed by aid, then is tightened bolt head with instrument, the fastening of bolt can be realized.Namely to realize spiral shell The fastening of bolt, needs 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. threaded rod Length it is longer when, then need two people to work simultaneously, waste time and energy and high labor intensive, especially producing in enormous quantities needs spiral shell The factory of bolt parts, not only production efficiency is low, while cost of human resources is high;If bolt is put into the through hole of connection member Afterwards, because the structure of space or connection member is limited, possibly inserter or cannot be difficult at bolt head, so as to affect bolt Fastening, and then 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 The part through hole of connection not on the same line, or because part appearance surfaces have high demands, can only be in the edge spiral shell of part Bolt throughhole, 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 The structure of the machining accuracy of connection member or accurate set parts realizing the assembling between connection member, so as to increase production The difficulty of technique, 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 easily twisting with hexagonal indentations threaded end Flexible bolt, this bolt arrange can standing screw hexagon termination and wing nut, can flexibly realize spiral shell in screw rod one end The fastening of bolt, it is time saving and energy saving, be conducive to improving production and work efficiency, while bolt hole can be met not on the same line Part connects, and is conducive to improving productivity ratio and work efficiency, while production cost is reduced, it is convenient and practical, it is applicable to various fields Close.
In order to achieve the above object, the technical scheme that this utility model is taken:
It is a kind of easily to twist flexibility bolt with hexagon 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, the nut is symmetrically arranged on two with two handles being bent upwards and in arc-shaped.
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, the screw rod by made by flexible spring steel material is set, part through hole company not on the same line is capable of achieving Connect, advantageously reduce production cost, screw rod is provided with the hexagonal indentations threaded end for fixing it, it is to avoid conventional bolt is tight Gu when need one end to fix, the drawbacks of the other end is tightened, the handle in arc-shaped be set on nut, lifting surface area is tightened in increase, And the torque on nut is acted on by leverage increase, convenient, flexible can realize the tight of connection member in bolt one end Gu, it is time saving and energy saving, labor intensity is reduced, be conducive to improve production efficiency and work efficiency, and it is convenient and practical, it is applicable to various Occasion.
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.
