Casing, as it is shown in fig. 7, have the delthyrium that cross section is triangular in shape, in order to ensure that rosette is installed on stripping forming back cabinet
Do not come off after in casing, also need after aluminum casing molding delthyrium is processed.
The step being processed the delthyrium of aluminum casing is as follows: 1, holed at delthyrium by drill bit；2, boring
The hole internal tapping gone out processes female thread.Rosette could be fixed on after only processing screwed hole by the way of screw machine
On shell.After casing molding, also need to successively carry out boring due to this connected mode and tapping is processed, prolong to a certain extent
Grow process time, thus reduce work efficiency.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, it is proposed that one can be directly firm with delthyrium
The many ribs tooth tapping screw connected.
The purpose of the present invention can be realized by following technical proposal:
This many ribs tooth tapping screw, including a body and the body of rod that is connected with head body, it is characterised in that tool on the described body of rod
Having at least three equally distributed scroll teeth, form helicoid between two adjacent rib teeth, the point on described helicoid is to bar
The vertical dimension of body axis to the vertical dimension of body of rod axis, the described body of rod also has spiral less than the point on rib tooth
Groove, this spiral fluted helical angle, more than the helical angle of rib tooth, is formed with screw thread between two adjacent helicla flutes.
Spiral fluted rotation direction is identical with the rotation direction of rib tooth, when being connected with delthyrium, is positioned at the screw thread extruding three at rib tooth
The medial wall of corner apertures, makes the medial wall of delthyrium form female thread, and this female thread is good with the threaded engagement being positioned on helicoid,
Effectively limit body of rod axially-movable in delthyrium, and ensure that at least three helicoids contact with the medial surface of delthyrium,
Circumference good limit effect.
In above-mentioned many ribs tooth tapping screw, described rib tooth is 3-9 bar.
In above-mentioned many ribs tooth tapping screw, described rib tooth is 6.Rib tooth is 6, then the helicoid formed is 6
Individual, improve the contact probability of helicoid and delthyrium medial surface, improve the delthyrium circumference limit to this tapping screw further
Position effect.
In above-mentioned many ribs tooth tapping screw, the cross section of described screw thread is isosceles triangle.
In above-mentioned many ribs tooth tapping screw, the vertical dimension of the joining of described rib tooth and screw thread to the bottom of thread
Being crossed to form helix for h1, described screw thread and helicoid, the vertical dimension at the midpoint of this helix to the bottom of thread is h2,
H2/h1=4/5.
In above-mentioned many ribs tooth tapping screw, the helical angle of rib tooth is 5 °-15 °.
In above-mentioned many ribs tooth tapping screw, the helical angle of described rib tooth is 8 °.
In above-mentioned many ribs tooth tapping screw, the end of described head body has cross recess.
The forming process of this many ribs tooth tapping screw is as follows:
1, a circle iron wire finished product is cut into segment；
2, segment is put into and on punch press, carry out punching press, it is achieved first one-step forming；
3, the semi-finished product of first one-step forming are put into thread rolling processing in screw plate, forms finished product.
Compared with prior art, this many ribs tooth tapping screw has the advantage that
Directly can be connected cooperation with delthyrium by this screw, for casing, the later stage without boring after again tapping add
Work screw thread, omits two procedures, is effectively increased the working (machining) efficiency of casing；And with the connecting of delthyrium after will not be from triangle
Come off in hole, axially with circumference good limit effect, improve the connective stability of rosette and casing.

Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
Many ribs tooth tapping screw as shown in Figure 1, Figure 2 and Figure 3, including a body 1 and the body of rod 2 that is connected with head body 1, the body of rod
There are on 2 at least three equally distributed scroll teeth 3, between two adjacent rib teeth 3, form helicoid 4, the point on helicoid 4
To the vertical dimension of the body of rod 2 axis less than the point on rib tooth 3 to the vertical dimension of the body of rod 2 axis, the body of rod 2 also has spiral shell
Spin slot 5, the helical angle of this helicla flute 5, more than the helical angle of rib tooth 3, is formed with screw thread 6 between two adjacent helicla flutes 5.
