Abstract
The utility model discloses a kind of steel house fixing screws, including nut, screw rod, tip, one end hold-doun nut of screw rod, the other end of screw rod is fixed and tension screw thread is provided with tip, screw rod, and tension screw thread includes the first inclined-plane and the second inclined-plane, first inclined-plane is the flank that angle of inclination is 30 °, second inclined-plane and the first inclined-plane incline direction identical flank, its angle of inclination are 5 °, and nut, which is fixed on the side of screw rod, is provided with anti-skid bulge；The tension screw thread that section is hangnail type is provided with screw rod, larger pulling force can be born when entering carrier, so that the utility model is difficult to pull out from carrier, and is provided with anti-skid bulge on nut, be not in situation about disassembling after the utility model enters carrier.
Description
Technical field
The utility model is related to the fixing component technical field of steel house, and more particularly to a kind of steel house fixes spiral shell
Nail.
Background technology
Need to use screw in steel house building course and be fixed.Screw thread on the screw of prior art is triangle
Shape, its tension effect of the screw thread of triangle is bad, is easily pulled out in the presence of external force from carrier, and screw is fixed to and carried
Easily rotation is disassembled after on body so that the steel house of construction has potential safety hazard.
Utility model content
It is good that the technical problems to be solved in the utility model is to provide a kind of tension effect, fixed to will not dismantle after on carrier
The steel house fixing screws got off.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：Steel house fixing screws, including spiral shell
The nut is fixed in cap, screw rod, tip, one end of the screw rod, and the other end of the screw rod fixes the tip, the screw rod
On be provided with tension screw thread, the tension screw thread includes the first inclined-plane and the second inclined-plane, and first inclined-plane is that angle of inclination is
30 ° of flank, second inclined-plane and the first inclined-plane incline direction identical flank, its angle of inclination are 5 °, institute
State nut and be fixed on the side of the screw rod and be provided with anti-skid bulge.
It is preferred that, the screw rod is provided between excessive screw thread, the excessive screw thread gradually with the sophisticated junction
Reduce.
It is preferred that, the anti-skid bulge is circular arc, and it is uniformly arranged six on the nut.
It is preferred that, the screw rod is provided with excessive neck close to one end of the nut.
It is preferred that, the nut, screw rod and tip are integral using stainless steel casting.
Using having the beneficial effect that above-mentioned technical proposal the utility model is obtained：Section is provided with screw rod for hangnail type
Tension screw thread, enter carrier when can bear larger pulling force so that the utility model be difficult from carrier pull out, and
Anti-skid bulge is provided with nut, is not in situation about disassembling after the utility model enters carrier.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only

Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of the utility model screw cap end.
In figure：1- nuts, 2- screw rods, 3- tensions screw thread, the excessive screw threads of 4-, 5- tips, 6- anti-skid bulges, 7- second are oblique
Face, the inclined-planes of 8- first.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other
It can just be mutually combined.
The utility model is further described with reference to accompanying drawing, person of ordinary skill in the field is preferably implemented this reality
With new, the utility model embodiment steel house fixing screws, including nut 1, screw rod 2, tip 5, one end of screw rod 2 is fixed
Nut 1, the other end of screw rod 2 is fixed and tension screw thread 3 is provided with tip 5, screw rod 2, and tension screw thread 3 includes the first inclined-plane and the
Two inclined-planes 7, the first inclined-plane is the flank that angle of inclination is 30 °, the second inclined-plane 7 and the first inclined-plane incline direction identical screw thread
Face, its angle of inclination is 5 °, and nut 1, which is fixed on the side of screw rod 2, is provided with anti-skid bulge 6.
The utility model embodiment screw rod 2 is provided between excessive screw thread 4, excessive screw thread 4 gradually with sophisticated 5 junction
Reduce so that the utility model preferably enters in carrier；Anti-skid bulge 6 is circular arc, and it is uniformly arranged six on nut 1
It is individual；Screw rod 2 is provided with excessive neck close to one end of nut 1；Nut 1, screw rod 2 and tip 5 are cast into one using stainless steel
It is overall.
The utility model embodiment is provided with the tension screw thread 3 that section is hangnail type on screw rod 2, the energy when entering carrier
Enough bear larger pulling force so that the utility model is difficult to pull out from carrier, and anti-skid bulge 6 is provided with nut 1,
It is not in situation about disassembling that the utility model, which enters after carrier,.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within protection domain of the present utility model.
