Abstract
The utility model discloses a connect stable large -sized bolt, including annular fastener, mounting hole, threaded connection hole, threaded rod, hexagon head, nut, gasket and blotter, the annular fastener is doughnut -shaped structure, and the central hollow structure that is, forms the mounting hole, and the bottom at annular fastener edge is equipped with multiunit threaded connection hole, and the inside in threaded connection hole is equipped with the helicitic texture, and threaded connection is passed through in the threaded connection hole the one end of threaded rod, a set of hexagon head of end fixing of the threaded rod other end is equipped with the helicitic texture, and through a set of nut of threaded connection, gasket and blotter have been put to the cover on the body of rod of threaded rod, just on the body of rod of threaded rod the gasket is contradicted at the terminal surface of nut. The utility model discloses, simple structure, multiunit bolt use with a set of bolt head, are favorable to the force balance between the bolt, and the ridge of protection bolt improves its life -span, can improve the connection stability of the device between to parts simultaneously, are fit for the fastening between the cylindrical parts.
Description
Technical field
This utility model is related to machine components technical field, specially a kind of large-sized bolt of stable connection.
Background technology
The bolt being presently used for connecting between two large components is only a shank of bolt and nut, in long work
Make lower it is more likely that occurring loosening phenomenon, and single screw thread stress, frequently can lead to thread damage, break down, additionally, by
Fastening between some circular ring parts is not that a bolt can be fixed, thus generally require multiple use cooperatively,
With the use of when, because the stressing conditions of each bolt are different, so easilying lead to discontinuity.
Content of the invention
The purpose of this utility model is to provide a kind of large-sized bolt of stable connection, to solve to carry in above-mentioned background technology
The problem going out.
For achieving the above object, this utility model provides a kind of following technical scheme: large-sized bolt of stable connection, including
Annular fastener, installing hole, threaded connection hole, threaded rod, turret head, nut, pad and cushion pad, described annular fastener be
Cirque structure, and center is hollow-core construction, forms installing hole, the bottom at annular fastener edge is provided with multigroup threaded
Hole, threaded connection hole be internally threaded structure, and threaded connection hole is threaded connection one end of described threaded rod, screw thread
One group of turret head is fixed in the end of the bar other end, and the body of rod of threaded rod is provided with helicitic texture and is threaded connection one group of spiral shell
Mother, on the body of rod of threaded rod, set is placed with pad and cushion pad, and described pad is conflicted in the end face of nut.
Preferably, the hand of spiral phase of the hand of spiral of described threaded connection hole internal whorl and described nut interior screw thread
With.
Preferably, described cushion pad is sped structure.
Preferably, the angle and distance all same being spaced between threaded connection hole described in two adjacent groups.
Preferably, the structure width of described turret head is less than the radius of described threaded rod.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, and multigroup bolt uses
Same group of bolt head, is conducive to stress balance between bolt, the ridge of protection bolt, improves its life-span, can improve this simultaneously
Device is for the connective stability between part, the fastening between suitable cylindrical parts.
Brief description
Fig. 1 is a kind of structural representation of the large-sized bolt of stable connection of this utility model；
In figure: 1. annular fastener, 2. installing hole, 3. threaded connection hole, 4. threaded rod, 5. turret head, 6. nut, 7. pads
Piece, 8. cushion pad.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of embodiment that this utility model provides: a kind of large-sized bolt of stable connection, including annular
Fastener 1, installing hole 2, threaded connection hole 3, threaded rod 4, turret head 5, nut 6, pad 7 and cushion pad 8, described annular fastening
Body 1 is cirque structure, and center is hollow-core construction, forms installing hole 2, the bottom at annular fastener 1 edge is provided with multigroup spiral shell
Stricture of vagina connecting hole 3, threaded connection hole 3 be internally threaded structure, and threaded connection hole 3 is threaded connection described threaded rod 4
One end, the end of threaded rod 4 other end fixes one group of turret head 5, and the body of rod of threaded rod 4 is provided with helicitic texture and passes through
Threaded one group of nut 6, on the body of rod of threaded rod 4, set is placed with pad 7 and cushion pad 8, and described pad 7 is conflicted in nut 6
End face；The hand of spiral of described threaded connection hole 3 internal whorl is identical with the hand of spiral of described nut 6 internal whorl；Institute
Stating cushion pad 8 is sped structure；The angle and distance all same being spaced between threaded connection hole 3 described in two adjacent groups；Described
The structure width of turret head 5 is less than the radius of described threaded rod 4.
Specifically used mode: it would be desirable to the part connecting passes through installing hole 2, by hexagonal in utility model works
5 by each threaded connection hole 3, you can be engaged all parts in order by spanner.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new
