Twist, yi word pattern, cross, five jiaos, the polygon screw such as hexagonal, to be tightened or unscrewed by screwing tool；In actual production
Machine application in, because the frequency of use of screw is very high, often make screw hole more arris be screwed it is weary, hence in so that screw work
Frictional force between tool and screw hole is very small, can not turn screw, is badly in need of improving.
Utility model content
The purpose of this utility model, which is to provide in a kind of reasonable in design, screw hole, sets spiral shell to spend, increasing friction force, just
In the screw turned.
A kind of built-in milled screw provided by the utility model, including screw head and screw rod, the screw rod is from the bottom of screw head
Extend downwardly, the screw rod includes the body of rod, and the perisporium of the body of rod is provided with screw thread, and the screw head is cylindrical structure, the circle
It is inside from the top surface provided with the top surface corresponding with the bottom of the screw head on column structure, provided with flight, the spiral shell
Silk groove includes flat body portion and cone portion, and the inner section in the flat body portion is closed by multiple planes to be formed by connecting, the cone portion by
The flat body portion, which extends internally, to be formed；The multiple plane is spent provided with some bar shaped spiral shells, and several described spiral shells, which are spent, uniformly to be divided
Cloth is on the surface of the plane.
It is further that the bar shaped spiral shell flower is parallel with the direction of the screw rod.
It is further that the section in the flat body portion is formed by connecting by six plane closings.
It is further to be inwardly formed six inclined-planes from six planes, the cone is closed by six inclined-planes
It is formed by connecting.
It is further that the cone portion is the cone being inwardly formed from six planes.
Built-in milled screw in the utility model, the screw include screw head and screw rod, and screw rod includes the body of rod, the perisporium of the body of rod
Provided with screw thread, screw head is cylindrical structure, and cylindrical structure is provided with the top surface corresponding with the bottom of the screw head, described in
Top surface is inside, and provided with flight, the flight includes flat body portion and cone portion, and the inner section in the flat body portion is by multiple planes
Closing is formed by connecting, and multiple planes are spent provided with some bar shaped spiral shells, and several spiral shells flower is evenly distributed on the plane
Surface.Therefore, the built-in milled screw of the utility model embodiment, due to being provided with several spiral shells flower, increase in flight
Frictional force between flight and screw tool so that screw tool is more preferable, is easier to turn screw, prevents screw due to screw
Multiple corner angle are screwed situation weary to turn in groove, and therefore, practicality is stronger.
Brief description of the drawings
It is required in being described below to embodiment to use in order to illustrate more clearly of the technical solution of the utility model
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some accompanying drawings of the utility model embodiment,
For those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to these accompanying drawings
Other accompanying drawings.
Fig. 1 is a kind of structural representation of the embodiment of built-in milled screw of the present utility model.
Fig. 2 is a kind of overlooking the structure diagram of the embodiment of built-in milled screw of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, it is a kind of structural representation of the embodiment of built-in milled screw of the present utility model；Such as Fig. 2 institutes
Show, for a kind of overlooking the structure diagram of the embodiment of built-in milled screw of the present utility model；The built-in annular knurl of the present embodiment
Screw, including screw head 1 and screw rod 2, the screw rod 2 extend downwardly from the bottom of screw head 1, and the screw rod 2 includes the body of rod, the bar
The perisporium of body is provided with screw thread 21, and the screw head 1 is cylindrical structure, on the cylindrical structure, provided with the bottom with the screw head 1
Corresponding top surface is held, inside from the top surface, provided with flight 11, the flight 11 includes flat body portion and cone portion, institute
The inner section for stating flat body portion is formed by connecting by the closing of multiple planes 111, and the cone portion is extended internally by the flat body portion and formed；
The multiple plane 111 spends 3 provided with some bar shaped spiral shells, and several described spiral shells spend 3 tables for being evenly distributed on the plane 111
Face.
Preferably, in the present embodiment, the bar shaped spiral shell spend it is 3 parallel with the direction of the screw rod 2, that is, in flight,
The spiral shell spends 3 to be spent for horizontal bar shaped spiral shell, exemplary, can be small raised line.
In the present embodiment, the section in flat body portion is formed by connecting by six closings of planes 111, from six planes 111 to
Six inclined-planes 112 of interior formation, the cone are formed by connecting by six closings of inclined-plane 112.
Alternatively, the cone portion is the cone being inwardly formed from six planes 111.
