This self tapping hangs screw includes the head, and the pole portion that sets up with the head coaxial line is equipped with the screw thread that the cross -section is triangle -shaped, its characterized in that in pole portion: be equipped with the screw hole on the head, the screw thread of this screw hole adopts machine -processed screw thread.
Description
Technical field
This utility model belongs to the technical field of self tapping hanging screw.
Background technology
At present, existing self tapping hanging screw includes that hexagon-head and bar portion, hexagon-head and bar portion are coaxially set, and is provided with the screw thread that cross section is triangular in shape in bar portion.Using the self tapping hanging screw of this structure, it can only be connected with other workpiece, and it only has the effect of fastening.
Summary of the invention
The purpose of this utility model is to provide a kind of self tapping hanging screw, and it had both had the effect of fastening, and had had again the effect of connection.
For solving above-mentioned technical problem, the purpose of this utility model is achieved in that a kind of self tapping hanging screw, including head, the bar portion being coaxially set with head, bar portion is provided with the screw thread that cross section is triangular in shape, it is characterized in that: be provided with screwed hole on described head, the screw thread of this screwed hole uses machined thread.
On the basis of such scheme and as the preferred version of such scheme: described screwed hole extends to direction, bar portion from the end face of head.
On the basis of such scheme and as the preferred version of such scheme: described screwed hole is coaxially set with bar portion, and the major diameter of thread of screwed hole is less than bar portion external diameter.
On the basis of such scheme and as the preferred version of such scheme: the axis of described screwed hole and the axis perpendicular of head.
On the basis of such scheme and as the preferred version of such scheme: between screw thread and the tail end in bar portion that described cross section is triangular in shape, there is distance, the position being positioned at screw thread rear triangular in shape, described cross section in bar portion is provided with chip area, this chip area extends to the tail end in bar portion, and a sidewall of chip area and the intersection, side in bar portion have cutting edge.
On the basis of such scheme and as the preferred version of such scheme: described head is hexagonal flange head.
This utility model highlights and useful having the technical effect that compared to existing technology
Self tapping hanging screw of the present utility model, by setting up the structure of screwed hole, can allow a self tapping hanging screw is simultaneously connected with at least two workpiece end to end, and it not only plays a part fastening, and play a part connection, and do not affect the exterior quality of workpiece itself.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 1 Fig. 2;
Embodiment one,
This gives a kind of self tapping hanging screw, it includes head 1 and bar portion 2.Wherein, head 1 is hexagonal flange head.Certainly, head can also use other shapes of head.Bar portion 2 is coaxially set with head 1, is provided with cross section screw thread triangular in shape 3 in bar portion 2, is provided with screwed hole 4 on described head 1, and the screw thread of this screwed hole uses machined thread.Machined thread is alternatively referred to as machine screw thread, typically uses coarse thread.Screwed hole 4 plays the effect of connection, and it carries externally threaded standard component precession screw head for one, enables this to carry externally threaded standard component and is fixed on self tapping hanging screw.In the present embodiment, described screwed hole 4 extends to direction, bar portion 2 from the end face 11 of head 1.As shown in FIG., being provided with a counter sink on head, counter sink extends along the axis direction of head, processes machined thread, thus form screwed hole on head on the sidewall of this counterbore.As the directly deformation of the thread pore structure of this structure, screwed hole can also be formed by processing machined thread on the sidewall of counterbore.
This self tapping hanging screw is by setting up the structure of screwed hole, and can allow a self tapping hanging screw is simultaneously connected with at least two workpiece end to end, and it not only plays a part fastening, and plays a part connection, and does not affect the exterior quality of workpiece itself.
In the present embodiment, described screwed hole 4 is coaxially set with bar portion 2, and the major diameter of thread of screwed hole is less than bar portion external diameter.By using this structure, owing to the diameter of screwed hole is relatively small so that head and bar portion have bigger intensity, and it can bear bigger moment of torsion.
In the present embodiment, between screw thread 3 and the tail end 21 in bar portion 2 that described cross section is triangular in shape, there is distance, the position being positioned at screw thread triangular in shape 3 rear, described cross section in bar portion 2 is provided with chip area 5, this chip area 5 extends to the tail end 21 in bar portion, one sidewall of chip area 5 and the intersection, side in bar portion 21 have cutting edge 6, form cutting drilling when being screwed into self tapping hanging screw, the bits cut can be discharged by chip area.It is noted that in the present embodiment, alleged " rear " is with the cephalad direction of self tapping hanging screw as front, and tail end is that the orientation at rear defines.
Embodiment two
The self tapping hanging screw that the present embodiment is given is roughly the same with the self tapping hanging screw structure in embodiment one, and the difference of the two is: the axis of described screwed hole and the axis perpendicular of head.Use this structure, owing to head is bigger with bar portion interface so that this self tapping hanging screw can carry bigger moment of torsion.Preferably, the axis of screwed hole and the axes intersect of head.
Above-described embodiment is only preferred embodiment of the present utility model, limits protection domain of the present utility model the most according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, within protection domain of the present utility model all should be covered by.
Claims (6)
1. a self tapping hanging screw, including head, the bar portion being coaxially set with head, is provided with the screw thread that cross section is triangular in shape in bar portion, it is characterised in that: being provided with screwed hole on described head, the screw thread of this screwed hole uses machined thread.
Self tapping hanging screw the most according to claim 1, it is characterised in that: described screwed hole extends to direction, bar portion from the end face of head.
