Description
Technical field
The utility model belongs to fastening screw technical field, specifically, and the utility model is related to a kind of internal-external hexagon cup
Head screw.
Background technology
Fastening bolt now is all that locking connection is realized by threaded engagement, is all that independent bolt passes through through hole
Or screwed hole realizes connection, in the presence of mechanical oscillation or alternate load, fastening bolt is easy to loosen, if
Find to tighten it not in time, it is easy to cause the damage of plant equipment or cause the accident.
Utility model content
The utility model provides a kind of internal-external hexagon hexagonal socket head cap screw, improve the stability that fastening bolt is tightened, it is to avoid
Occur loosening in the presence of mechanical oscillation or alternate load or come off.
To achieve these goals, the technical scheme that the utility model is taken is：A kind of internal-external hexagon hexagonal socket head cap screw, including
Hex bolts body, hexagon socket head cap screw and taper strut, the taper strut are connected with hexagon socket head cap screw front end, the interior hexagonal
Bolt is connected with hex bolts body by screw pair.
It is preferred that, the hex bolts body upper end is provided with counter sink, and centre is provided with screwed hole, and lower end is provided with taper chamber.
It is preferred that, the lower end of the hex bolts body is provided with elongated slot, and elongated slot direction and the axis of hex bolts body
Direction is consistent.
It is preferred that, the taper chamber is made up of three cone walls.
Beneficial effect using above technical scheme is：The internal-external hexagon hexagonal socket head cap screw, with spanner by hex bolts body
It is screwed into connected structural member, is then threaded into hexagon socket head cap screw in hole through counter sink with die nut, until cone
Degree strut is contacted with taper chamber, then proceedes to twist hexagon socket head cap screw, then taper strut acts cone wall power, then
It will be tensioned between hex bolts body and connected structural member, improve the stability tightened of fastening bolt, it is to avoid in machinery
Occur loosening or come off in the presence of vibration or alternate load.

Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figure 1 to Figure 3, the utility model is a kind of internal-external hexagon hexagonal socket head cap screw, and it is steady that raising fastening bolt is tightened
It is qualitative, it is to avoid to occur loosening in the presence of mechanical oscillation or alternate load or come off.
Specifically, as shown in Figure 1 to Figure 3, including hex bolts body 1, hexagon socket head cap screw 2 and taper strut 3, such as scheme
1st, shown in Fig. 3, the taper strut 3 is connected with the front end of hexagon socket head cap screw 2, and the hexagon socket head cap screw 2 leads to hex bolts body 1
Cross screw pair connection.
As shown in figure 1, the upper end of hex bolts body 1 is provided with counter sink 10, centre is provided with screwed hole 11, and lower end is provided with
Taper chamber 12.
As shown in Figure 1 and Figure 2, the lower end of the hex bolts body 1 is provided with elongated slot 13, and the direction of elongated slot 13 and hexagonal spiral shell
The axis direction of bolt body 1 is consistent.The taper chamber 12 is made up of three cone walls 14.Below with specific embodiment to specific
Working method is illustrated：
Hex bolts body 1, is screwed into connected structural member by the internal-external hexagon hexagonal socket head cap screw with spanner, then with six
Hexagon socket head cap screw 2 is threaded into hole 11 by angle spanner through counter sink 10, until taper strut 3 is contacted with taper chamber 12, so
Afterwards continue twist hexagon socket head cap screw 2, then taper strut 3 power is acted to cone wall 14, then by hex bolts body 1 with
It is tensioned between connected structural member, improves the stability tightened of fastening bolt, it is to avoid in mechanical oscillation or alternate load
In the presence of occur loosening or come off.
The utility model is exemplarily described above in association with accompanying drawing, it is clear that the utility model is implemented not
Limited by aforesaid way, as long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
