Description
Technical field
Machine components equipment technical field is the utility model is related to, specially a kind of self-drilling self-tapping nail.
Background technology
Tapping screw is voluntarily to attack the one kind for drilling out negative thread joined together in the prebored hole of metal or nonmetallic materials to have
Threaded fasteners.Tapping screw is used for the connection between thin metallic plate (steel plate, saw plate etc.).During connection, first to connected piece
Thread Pilot hole is made, then tapping screw is screwed into the thread Pilot hole of connected piece.Because the thread surface of tapping screw has
Higher hardness (>=45HRC), can in the thread Pilot hole of connected piece tapping internal thread, so as to formed connection, due to its from
Its matching thread of capable shaping or tapping, therefore there is high anti-loose ability in combination, and can load and unload.Its chi on small shape screw
It is very little, screw type, head dummy, attack brill performance and almost know no measure on engineering purposes, but some screws still have some not
Foot, for example, screw nut installation when, due to there is no thread on nut, it is impossible to shoot the inside of sheet material, it is often necessary to
Reaming, which enhances working strength.
Utility model content
The purpose of this utility model is to provide a kind of self-drilling self-tapping nail, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of self-drilling self-tapping nail, including burr-drill, spiral shell
The head of a nail, external screw teeth, cylinder, head of screw, cross recess and pyramid, the screw cap, cylinder and head of screw form self-drilling self-tapping nail
Body, and cross recess and six pyramids are respectively arranged with the two sides of screw cap, the outside of the cylinder is uniformly set
There is external screw teeth, and the both sides of the head of screw of post tips setting are provided with pyramid.
Preferably, the burr-drill is uniformly arranged on screw cap, and the thickness of burr-drill is 2mm.
Preferably, the cylinder is stainless steel component.
Preferably, the plus screw is arranged at the center of screw cap, and the depth of the one of groove of cross recess
It is identical with the length of conventional flathead screwdriver cutter head.
Compared with prior art, the beneficial effects of the utility model are：This product is provided with six on the inside of screw cap
Pyramid so that device when in use can perfectly be combined screw cap with sheet material, without carrying out reaming, pole with drill bit
Big reduces work task efficiency, while has also carried work task efficiency, and cross recess is provided with the outside of device,
And the depth of one of groove is identical with the length of flathead screwdriver cutter head, so that device can both use Philip's head screw
Knife, flathead screwdriver can be used again, the scope of application is wider, while the pyramid that head of screw both sides are set further expands tapping
Hole, the entrance of external screw teeth is more beneficial for, saves the muscle power of worker, this product is simple in construction, reasonable in design, is adapted to promote and fits
With.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structural representation on the inside of the utility model screw cap；
Fig. 3 is the structural representation on the outside of the utility model screw cap；
Fig. 4 is the structural representation of the utility model head of screw.
In figure：1 burr-drill, 2 screw caps, 3 external screw teeths, 4 cylinders, 5 head of screws, 6 cross recess, 7 pyramids.
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.
Fig. 1-4 are referred to, the utility model provides a kind of technical scheme：A kind of self-drilling self-tapping nail, including burr-drill 1, screw
Cap 2, external screw teeth 3, cylinder 4, head of screw 5, cross recess 6 and pyramid 7, screw cap 2, cylinder 4 and head of screw 5 are formed from brill certainly
Nail body is attacked, and cross recess 6 and six pyramids 7 are respectively arranged with the two sides of screw cap 2, pyramid 7 make it that screw cap can
Shoot in sheet material, and not carry out reaming reduces the working strength of worker, the outside of cylinder 4 is uniformly provided with external screw teeth 3,
Be advantageous to closely be bonded with sheet material, and the both sides of the head of screw 5 of the end of cylinder 4 setting are provided with pyramid 7, pyramid 7 is further
Tapping hole is expanded, is more beneficial for the entrance of external screw teeth 3, saves the muscle power of worker, burr-drill 1 is uniformly arranged on screw cap 2
On, and the thickness of burr-drill 1 is 2mm, cylinder 4 is stainless steel component, ensures the intensity of product, and cross recess 6 is arranged on spiral shell
At the center of the head of a nail 2 so that the uniform force of product, and the depth of 6 one of groove of cross recess and conventional flat head screw
The length of knife cutter head is identical so that device can both use Phillips screwdriver, can use flathead screwdriver again, and the scope of application is wider.
Operation principle：Only need to select flathead screwdriver or Phillips screwdriver when in use, cutter head is placed on spiral shell
In cross recess 6 on the head of a nail 2, head of screw 5 is then directed at sheet material and firmly turns screwdriver so that head of screw 5 enters plate
In material, while the pyramid 7 of the both sides of head of screw 5 further expands tapping hole, is more beneficial for the entrance of external screw teeth 3, exerts oneself always
The turn of the screw knife enters in sheet material until screw cap 2.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
