Description
Technical field
The utility model is related to screw field, specially a kind of stainless steel screw.
Background technology
Screw is common in machinery, and the manufacture of electrical equipment and building etc., generally metal is cylindrical, and surface quarter is irregular
Ditch, such as one inclined plane around screw side allows screw tightly to lock work cap nut or other objects.The top diameter of screw compared with
Greatly, can be rounded or hexagon be waited, allows the rotatable screw of instrument such as screwdriver or spanner.More prominent top also makes screw not
Can be drilled too deeply and through material, and improve pressure of the screw to material.Entered in existing ammeter box using common screw
Row is tightened, and power stealing person is sneaked current after ammeter box is opened after often screw reversely can be back-outed.Can so ammeter be caused to lose
Go metering to act on, cause power supply department economic loss.Poor safety performance.
The content of the invention
The purpose of this utility model is to provide a kind of stainless steel screw, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of stainless steel screw, including nut and
Screw rod, the nut is fixed on one end of screw rod, and the other end of the screw rod is provided with tip, the screw rod provided with threaded portion and
Non-threaded portion, the non-threaded portion is at nut, and the non-threaded portion is provided with pad, and the pad and screw rod one into
Type, the both sides of the tip are provided with unscrewed tooth, and the screw flight portion is provided with pawl.
It is preferred that, the length of the threaded portion is 2-3 times of the length in non-threaded portion.
It is preferred that, spiral shell cutter groove is provided with the nut, and the spiral shell cutter groove is in-line or cross.
It is preferred that, the thickness of the pad is 1mm-2mm.
It is preferred that, the nut and screw rod use 304 stainless steels or 316 stainless steels.
Compared with prior art, the beneficial effects of the utility model are：
（1）The utility model novel in structural design, penetration capacity is strong when being screwed into, while can prevent anti-after screw-driving
To back-outing, security is improved.
（2）Screw flight portion of the present utility model is provided with pawl, it is possible to increase the firmness after tightening, while can
Further prevent from being reversed back-outing.
（3）Non-threaded portion is provided with pad on screw rod of the present utility model, and pad is integrally formed with screw rod, using this knot
Structure, can prevent from tightening rear stripped thread.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
