Technical field
Building materials technical field is the utility model is related to, specially a kind of new screw.
Background technology
Screw rod, outer surface cut with the cylinder of helicla flute or cut with the circular cone of Conical Spiral Groove, and screw rod has different heads,
As the head in picture is outer-hexagonal screw rod, there are other, such as big flat screw rod, hexagon socket head cap screw etc., metric thread external diameter is
In units of millimeter, such as uniform pitch such as 6,8,10,12,18,20 millimeters are also in units of millimeter such as 0.5,0.75,1,1.5,
2,3, etc., inch screw thread external diameter is (per inch is equal to 25.4 millimeters) such as 3/16,5/8,1/4,1/2 in inches, etc.
Deng, so with metric system slide calliper rule amount external diameter reading often with irregular decimal, pitch made in Great Britain is to be represented with per inch containing how many individual teeth,
Slide calliper rule are scheduled on 25.4 millimeters, a chi point alignment screw thread cusp, another chi point such as alignment screw thread cusp is exactly spiral shell made in Great Britain
Line, if misalignment screw thread cusp should be metric thread.
At present in our widely used screw rods, structure is single, is used only for fixing some structures, and spiro rod length one
As after formation length fix, can not change so that cost of manufacture greatly increases, and under most occasions, can not find

There is a blocker ring, the spiral screw rod end is connected with connecting screw, is connected with overcoat on the outside of the connecting screw, outside the overcoat
Side is connected with screw head.
As a kind of preferable technical scheme of the utility model, the pressure-bearing post and protective case are in hexa-prism.
As a kind of preferable technical scheme of the utility model, the left hand thread is located at the outside of right-handed thread, described
Blocker ring is located between left hand thread and right-handed thread.
As a kind of preferable technical scheme of the utility model, the equal length of the pitman and connecting screw.
As a kind of preferable technical scheme of the utility model, the screw head is in coniform, and coniform screw head
Drift angle is 45 degree.
Compared with prior art, the beneficial effects of the utility model are：The pressure-bearing that the utility model passes through six prisms of setting
The nut of post and protective case and six prisms is mutually matched so that overall construction design collocation is reasonable, and protective case can prevent object
Friction occurs between screw rod body surface is caused to damage, and effectively prevent the skidding between object and screw rod, set left
Rotation and the collocation of right-handed thread, make the stable connection between nut and screw rod, set screw head that screw rod can be caused to be used for thing
Body surface drilling so that the practicality of screw rod is stronger, and the design of pitman and connecting screw, can be in the situation of needs
Under, extend the length of screw rod by the connection between spiral screw rod, overall construction design is ingenious, and practicality is very strong.
