Abstract

The utility model discloses a bolt with hexagonal groove threaded end, include bolt head, the threaded rod that links to each other with the bolt head, cooperate the nut of being connected with the threaded rod, the tip surface cover of threaded rod is equipped with the threaded end who connects rather than the cooperation, fixed threaded rod when threaded end is used for bolt tightening, just the last recess that is the hexagon structure of seting up of threaded end. But this bolt setting fixed threaded rod's hexagonal groove end needs the drawback that one end is fixed, one end is screwed up when avoiding traditional bolt -up, just can realize adapting unit's fastening in bolt one end, and labour saving and time saving reduces intensity of labour, be favorable to improving production efficiency and work efficiency, and guarantee the fastening connection between the adapting unit, and convenient and practical, it is applicable in multiple occasion, be worth extensively popularization.

Description

A kind of 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 bolt with hexagonal indentations threaded end.
Background technology
Bolt is widely used machine components, including bolt head and threaded rod, is needed and nut screw connection, for being fastenedly connected Two parts with through hole.This type of attachment claims bolt connection.As nut is screwed off from bolt, the two can be made again 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 threaded rod of stricture of vagina and the nut being connected with shaft, such bolt arrangement:Bolt In rundown process, due to stress, inevitably there are the phenomenons such as skid or rocking occurs in threaded rod in nuts and bolt head, so that In needs bolt head is fixed by aid, then with aid by nut screwing clamping, or needs will by aid Nut is fixed, then is tightened bolt head with instrument, can realize the fastening of bolt.The fastening of bolt is namely realized, is needed Fix in bolt one end simultaneously, the other end is tightened, if the part area of connection is big, thickness is thick, i.e. when the length of threaded rod is longer, Then need two people to work simultaneously, waste time and energy and high labor intensive, especially producing in enormous quantities needs bolt parts Factory, 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 space Or the structure of connection member is limited, possibly inserter or cannot be difficult at bolt head, so as to affect the fastening of bolt, Jin Erying Ringing work is carried out in order.
Utility model content
In view of the shortcomings of the prior art, this utility model provides a kind of spiral shell with hexagonal indentations threaded end Bolt, this bolt arranges the hexagonal indentations termination that can fix threaded rod, can just realize the fastening of bolt in threaded rod one end, saves time It is laborsaving, be conducive to improving production and work efficiency, it is convenient and practical, it is adaptable to numerous occasions.
In order to achieve the above object, the technical scheme that this utility model is taken:
A kind of bolt with hexagonal indentations threaded end, including the threaded rod that is connected with bolt head of bolt head and spiral shell The nut that rasp bar is connected, the end outer surface of the threaded rod is arranged with the threaded end being connected with it, the spiral shell The groove that hexagonal structure is offered on threaded rod, and the threaded end is fixed in stricture of vagina termination when tightening for bolt.
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, effectively prevent the loosening between connection member, the threaded rod On be arranged with the fit sealing part being connected with nut, the fit sealing part is spring shim or plain cushion molectron.
Compared with prior art, this utility model has the advantage that:
1st, threaded rod is provided with the hexagonal indentations threaded end for fixing it, it is to avoid conventional bolt needs one when fastening The drawbacks of end is fixed, the other end is tightened, in bolt one end the fastening of connection member is achieved that, time saving and energy saving, reduces work strong Degree, is conducive to improve production efficiency and work efficiency, convenient and practical, is applicable to various occasions.
The 2nd, the fit sealing part of spring shim or plain cushion molectron 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, threaded rod, 3, nut, 4, threaded end, 4-1, groove, 5, fit sealing part.
Specific embodiment
A kind of specific embodiment of this utility model, a kind of 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 with external screw thread and the threaded rod 2 and threaded rod 2 of cylindrical structure coordinate company The nut 3 for connecing, 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 different, the end outer surface of the threaded rod 2 be arranged with The threaded end 4 that it is connected, fixes threaded rod 2, and the threaded end 4 when the threaded end 4 is tightened for bolt On offer the groove 4-1 of hexagonal structure.
The fit sealing part 5 being connected with nut 3 is arranged with the threaded rod 2, the fit sealing part 5 is spring shim Or plain cushion molectron, fit sealing part 5 can expand the contact area of connection member and nut 3, be conducive to connecing for connection member Touch and tighten, while ensureing the firm connection between threaded rod 2 and nut 3, effectively prevent the loosening between connection member.
When this utility model is used:Threaded rod 2 is inserted in the through hole of the two or more parts for needing connection, spiral shell is determined Behind the position of bolt head 1, fit sealing part 5, nut 3, threaded end 4 are sequentially sleeved on threaded rod 2, it is for example interior with interior hex tool Hex wrench is put in hexagonal indentations 4-1, so as to fix threaded end 4, and then fixed threaded rod 2, then by opening Or double offset ring spanner is tightened to nut 3 on threaded rod 2, you can realize the fastening between connection member.
Certainly, simply combine accompanying drawing above to be described in detail this utility model preferred embodiment, not Practical range of the present utility model is limited with this, all equivalence changes made according to principle of the present utility model, construction and structure, All should be covered by protection domain of the present utility model.
