Abstract
The utility model discloses self -drilling screw belongs to mechanically fastening device field. The technical problems to be solved in the utility model are: not high temperature resistant, the easy oxidation of current self -drilling screw, perishable, not anti embroidery. The utility model provides a self -drilling screw, including nut, screw rod head, screw rod body and cutting portion, screw rod head, screw rod body and the integrated into one piece of cutting portion, the surface of screw rod body is equipped with the screw, and the material of nut is nylon, nut and screw rod head fixed connection, the surface of screw rod head, screw rod body and cutting portion has all plated the zinc layer. The beneficial effects of the utility model are that, self -drilling screw is high temperature resistant, tough pull out force with maintain the dynamic height, anti -oxidant, corrosion -resistant, rust resistance can be good.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of SELF DRILLING SCREWS.
Background technique
Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts.SELF DRILLING SCREWS is the WOOD SCREWS that there is self tapping drill head screw front end.Screw is the joint invention over the past thousands of years in people's productive life, and according to application, it is the first invention of the mankind.SELF DRILLING SCREWS is the new invention of people in recent years, is also self tapping screw.The afterbody of SELF DRILLING SCREWS, need not secondary process in boring tail or fine stern shape, directly arranging boring, tapping, locking on material, basic material, significantly can save the engineering time.But, existing SELF DRILLING SCREWS non-refractory, easily oxidation, perishable, not anti-embroidery.
Model utility content
The purpose of this utility model is to provide a kind of high temperature resistant, tough pull out force and maintenance energy is high, anti-oxidant, corrosion-resistant, the SELF DRILLING SCREWS of rust-proofing.
For achieving the above object, the utility model adopts following technological scheme:
The utility model SELF DRILLING SCREWS, comprise nut, screw head, screw body and cutting portion, screw head, screw body and cutting portion are one-body molded, the outer surface of screw body is provided with screw thread, the material of nut is nylon, nut is fixedly connected with screw head, and the outer surface of screw head, screw body and cutting portion is all coated with zinc layers.
The utility model SELF DRILLING SCREWS difference from prior art is: one be the screw head of the utility model SELF DRILLING SCREWS, the outer surface of screw body and cutting portion is all coated with zinc layers, such that the utility model SELF DRILLING SCREWS is anti-oxidant, corrosion-resistant, the performance of rust-proofing strengthens greatly; Two is that screw head is fixedly connected with nut, and nut is nylon material, further increases anti-oxidant, corrosion-resistant, the rust-resisting property of screw head; In addition, because nut is fixedly connected with screw rod by injection moulding, so, can select the nut of different colours when injection moulding, the nut that color is various and ornament material combine, and will inevitably bring decorative effect.
The utility model SELF DRILLING SCREWS, this end that described screw head is connected with nut is dop of blooming.
Dop of blooming is convenient to nut and is injection-moulded on screw rod.
The utility model SELF DRILLING SCREWS, the other end of described nut has groove.
The utility model SELF DRILLING SCREWS, described groove is hexagonal groove.
The anastomose property of hexagonal groove and power drill is better, is convenient to operation.
In sum, the beneficial effects of the utility model are, SELF DRILLING SCREWS is high temperature resistant, tough pull out force and maintenance energy is high, anti-oxidant, corrosion-resistant, rust-resisting property is good, and have decorative aesthetics.
Below in conjunction with accompanying drawing, SELF DRILLING SCREWS of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model SELF DRILLING SCREWS.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Fig. 3 is the structural representation of the utility model screw rod and cutting portion.
Fig. 4 is that B of the present utility model is to structural representation.
Embodiment
As shown in Figure 1, the utility model SELF DRILLING SCREWS, comprise nut 1, screw head 2, screw body 3 and cutting portion 4, screw head 2, screw body 3 and cutting portion 4 are one-body molded, the outer surface of screw body 3 is provided with screw thread, the material of nut 1 is nylon, and nut 1 is fixedly connected with screw head 2, and the outer surface of screw head 2, screw body 3 and cutting portion 4 is all coated with zinc layers.The utility model SELF DRILLING SCREWS in advance through Overheating Treatment, high temperature resistant, tough pull out force and maintenance energy high.
As shown in Figure 2, the groove on described nut 1 is hexagonal groove.
As shown in Figure 3, the other end of screw head 2 is provided with dop of blooming.
As shown in Figure 4, the bloom quantity of head of screw head 2 is 4.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
