Abstract

The present invention discloses a kind of bolt with hexagonal indentations threaded end, the nut being connected with shaft including bolt head, the threaded rod connected with bolt head, the end outer surface of described threaded rod is arranged with the threaded end being connected with it, described threaded end fixes, when bolt is tightened, the groove offering hexagonal structure on threaded rod, and described threaded end.This bolt arranges the hexagonal indentations termination that can fix threaded rod, conventional bolt is avoided when fastening, to need the drawback that one end is fixed, one end is tightened, the fastening of connection member is achieved that in bolt one end, time saving and energy saving, reduce labor intensity, be conducive to improving production efficiency and work efficiency, and being fastenedly connected between guarantee connection member, convenient and practical, it is applicable to multiple occasion, should be widely promoted.

Description

A kind of bolt with hexagonal indentations threaded end
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of bolt with hexagonal indentations threaded end.
Background technology
Bolt is widely used machine components, including bolt head and threaded rod, needs and nut screw connection, is used for being fastenedly connected Two parts with through hole.This type of attachment claims bolt to connect.As nut is screwed off from bolt, the two 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 Threaded rod that stricture of vagina is cylindrical and the nut being connected with shaft, there is following defect in such bolt arrangement: bolt In rundown process, due to stress, nuts and bolt head inevitably occurs that phenomenons such as rocking occur in skidding or threaded rod, so that Bolt head is fixed by aid in needs, then with aid by nut screwing clamping, or needs will by aid Nut is fixed, then is tightened by bolt head with instrument, can realize the fastening of bolt.The fastening of bolt to be realized, needs Fix in bolt one end, the other end is tightened simultaneously, if the parts area connected is big, thickness is thick, when i.e. the length of threaded rod is longer, Then needing two people to work simultaneously, waste time and energy and labor intensity is big, especially producing in enormous quantities needs bolt parts Factory, 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 space Or the structure of connection member limits, possibly inserter or cannot be difficult at bolt head, thus affect the fastening of bolt, Jin Erying Ring work to carry out in order.
Summary of the invention
The deficiency existed for prior art, the present invention provides a kind of bolt with hexagonal indentations threaded end, this Bolt arranges the hexagonal indentations termination that can fix threaded rod, can just realize the fastening of bolt in threaded rod one end, time saving and energy saving, Be conducive to improving and produce and work efficiency, convenient and practical, it is adaptable to numerous occasions.
In order to achieve the above object, the technical scheme that the present invention takes:
A kind of bolt with hexagonal indentations threaded end, the threaded rod including bolt head, being connected with bolt head and spiral shell The nut that rasp bar is connected, the end outer surface of described threaded rod is arranged with the threaded end being connected with it, described spiral shell The groove offering hexagonal structure on threaded rod, and described threaded end is fixed, when bolt is tightened, in stricture of vagina termination.
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 between connection member, described threaded rod On be arranged with the fit sealing part being connected with nut, described fit sealing part is spring shim or plain cushion molectron.
Compared with prior art, the invention have the benefit that
1, threaded rod is provided with the hexagonal indentations threaded end for fixing it, it is to avoid need one during conventional bolt fastening The drawback that end is fixing, the other end is tightened, achieves that the fastening of connection member in bolt one end, time saving and energy saving, reduces work strong Degree, is conducive to improving production efficiency and work efficiency, convenient and practical, is applicable to multiple occasion.
2, the fit sealing part of spring shim or plain cushion molectron 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.
Fig. 1 is the structural representation of the present invention;
The structural representation of the existing bolt of Fig. 2;
Drawing reference numeral: 1, bolt head, 2, threaded rod, 3, nut, 4, threaded end, 4-1, groove, 5, fit sealing part.
Detailed description of the invention
One specific embodiment of the present invention, a kind of bolt with hexagonal indentations threaded end, bag are proposed as shown in Figure 1 Include bolt head 1, be connected with bolt head 1 threaded rod 2 with external screw thread and cylindrical structure and threaded rod 2 are connected Nut 3, bolt head 1 can be arranged to turret head, round end, square spigot, countersunk head, and the present embodiment selects to be arranged to round end , the length of threaded rod 2 can need rationally to arrange according to difference, and the end outer surface of described threaded rod 2 is arranged with joins with it Closing the threaded end 4 connected, described threaded end 4 is fixed when bolt is tightened and is opened on threaded rod 2, and described threaded end 4 It is provided with the groove 4-1 of hexagonal structure.
Being arranged with the fit sealing part 5 being connected with nut 3 on described threaded rod 2, described fit sealing part 5 is spring shim Or plain cushion molectron, fit sealing part 5 can expand connecing of the contact area of connection member and nut 3, beneficially connection member Touch and tighten, ensure being firmly connected between threaded rod 2 and nut 3 simultaneously, effectively prevent loosening between connection member.
When the present invention uses: threaded rod 2 is inserted in the through hole of the two or more parts needing connection, determines bolt head Behind 1 position, fit sealing part 5, nut 3, threaded end 4 are sequentially sleeved on threaded rod 2, by the interior hexagonal of interior hex tool Hexagonal indentations 4-1 put into by shape spanner, thus fixes threaded end 4, and then fixing threaded rod 2, then by opening or Nut 3 is tightened on threaded rod 2 by double offset ring spanner, can realize the fastening between connection member.
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.
