Abstract
A screw (3) comprises a screw head (31) and a screw rod (32), wherein the screw head (31) has an outer hexagon (34) and an inner hexagon (33). The screw integrates an outer hexagonal screw and an inner hexagonal screw and can be screwed and fixed by various available spanners.
Description
Technical field
The utility model relates to a kind of fastening piece, in particular for the screw of component of machine fixed connection.
Background technique
At present, in engineering goods, screw commonly used carries out fixed connection.Existing screw has two kinds of common type, i.e. outer-hexagonal screw 1 as shown in Figure 1 and socket head screw as shown in Figure 22.
Outer-hexagonal screw 1 is made up of outer-hexagonal ailhead 11 and screw rod 12.Socket head screw 2 is made up of ailhead 21 and screw rod 22, wherein has interior hexagonal (hexagonal in the plum blossom) 24 in the cylindrical body 23 of ailhead 21.
Usually, outer-hexagonal screw 1 is usually used in interplanar and connects, and as shown in Figure 3, plane workpiece 41, plane workpiece 42 are fixedly connected by outer-hexagonal screw 1.
Usually, socket head screw is usually used in counterbore or groove connects, and as shown in Figure 4, workpiece 51 and plane workpiece 52 with counterbore are fixedly connected by socket head screw 2.
Yet, in actual use, in the time will using the outer-hexagonal screw, but for the moment can not find the outer-hexagonal screw, have only socket head screw; And can not find socket head screw for the moment will use socket head screw the time, have only the outer-hexagonal screw.
Summary of the invention
The purpose of this utility model is to provide a kind of new process structure screw, and a kind of screw not only can be worked as the outer-hexagonal screw but also can be worked as socket head screw, so just can solve above-mentioned practical problem.
For this reason, the utility model is achieved in that the shape fabricating of ailhead becomes the outer-hexagonal screw, the internal production socket head screw of ailhead.
The ailhead of screw of the present utility model had both had outer-hexagonal, had interior hexagonal again.
Obviously, the ailhead of screw of the present utility model also can be when having outer-hexagonal, also has hexagonal in the plum blossom.
Screw of the present utility model can pass through spanner wrench, and the outer-hexagonal that tightens the screw ailhead rotates.Simultaneously, also can rotate by the interior hexagonal that inner hexagon spanner (flower hexagon wrench) tightens the screw ailhead.
Be not subjected to the restriction of torque tool type during the utility model screw uses, both can be used with spanner wrench, again can with the supporting use of inner hexagon spanner, have the advantage of highly versatile, need not to change operating habit, easy and simple to handle.Save the time of seeking corresponding kind screw in the practical operation, increase work efficiency.
New structure screw kind is unified, has both helped manufacturing, saving expenditure, helps reducing the cost of enterprise in management again.
Obviously, the thread section of new structure screw can be made into different-diameter specification and length according to the use occasion difference, is widely used in engineering fields such as machine-building, five metals, mould, electromechanics, harbour machinery, mining machinery.
By improving, original outer-hexagonal and interior hexagonal are combined, make it to become one.The new structure screw still is tightened by existing various types of spanners, need not newly-increased assistant tool.
