Abstract
The utility model relates to fastener areas, more particularly to a kind of double end tungsten nickel screw, 1. including tighten up a screw head, lower screw terminal and screw rod, it is characterized in that, tighten up a screw a lower surface and the lower screw terminal fixed-link, the lower screw terminal lower surface are fixedly connected with screw rod, and a upper surface of tightening up a screw is provided with cross recess, the lower screw terminal section is hexagon, is provided with screw thread on the screw rod.The beneficial effects of the utility model are: using dual head design, the cross recess of head surface of tightening up a screw setting allows the utility model to twist fastening object using Phillips screwdriver；Lower screw terminal section is hexagonal design, can twist fastening object using outer hexagonal spanner；The through-hole of screw rod lower end setting increases fixed form, improves tightness.
Description
Technical field
The utility model relates to fastener areas more particularly to a kind of double end tungsten nickel screws.
Background technique
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The tool of implements parts.Screw is the general saying of fastener, is industrial necessity indispensable in daily life.Tungsten nickel closes
Gold is a kind of alloy with high-melting-point, high rigidity and high corrosion-resistant, and nickel content is lower than 10% or 10%~25%, and surplus is tungsten.
Screw is made using tungsten nickel material, has precision high, good mechanical performance, surface smoothness is high, material benefit
With rate height, the advantages such as manufacturing cost is low, the production suitable for high-volume part.Problem of the existing technology is installing and dismounting
Inconvenience, working efficiency are low.
Utility model content
In view of the above-mentioned deficiencies in the prior art, the utility model provides a kind of using simple, convenient disassembly double
Head tungsten nickel screw.
In order to realize the purpose of utility model, the utility model adopts the technical scheme that a kind of double end tungsten nickel screw,
Including head of tightening up a screw, lower screw terminal and screw rod, which is characterized in that tighten up a screw a lower surface and the lower screw terminal fixed-link,
The lower screw terminal lower surface is fixedly connected with screw rod, and a upper surface of tightening up a screw is provided with cross recess, the lower screw terminal
Section is hexagon, is provided with screw thread on the screw rod.
Further, the screw rod is made of tungsten nickel, and the head of tightening up a screw is made of tungsten nickel, the lower screw
Head is made of tungsten nickel.
Further, the screw rod lower end is provided with through-hole.
The beneficial effects of the utility model are: using dual head design, the cross recess of head surface of tightening up a screw setting keeps this practical
It is novel fastening object to be twisted using Phillips screwdriver；Lower screw terminal section is hexagonal design, can be pulled using outer-hexagonal
Hand twists fastening object；The through-hole of screw rod lower end setting increases fixed form, improves tightness.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Appended drawing reference in figure: 1, head of tightening up a screw；2, lower screw terminal；3, screw rod；4, screw thread；5, through-hole；6, cross recess.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment 1
A kind of double end tungsten nickel screw, including tighten up a screw first 1, lower screw terminal 2 and screw rod 3, which is characterized in that described to tighten up a screw
First 1 lower surface and lower 2 fixed-link of screw terminal, lower 2 lower surface of screw terminal are fixedly connected with screw rod 3, described to tighten up a screw first 1
Upper surface is provided with cross recess 6, and lower 2 section of screw terminal is hexagon, is provided with screw thread 4 on the screw rod 3.
Further, the screw rod 3 is made of tungsten nickel, and described tighten up a screw first 1 is made of tungsten nickel, the lower spiral shell
Silk head 2 is made of tungsten nickel.
Further, 3 lower end of screw rod is provided with through-hole 5.
In use, fastening tool can be selected according to installation environment, using Phillips screwdriver, by tighten up a screw first 1 ten
Word slot 6 fastens double end tungsten nickel screw；Outer hexagonal spanner can also be used, double end tungsten nickel screw is fastened by lower screw terminal 2；?
After fastening, plug-in unit can be inserted into through-hole 5, further fasten, prevent from rotating.
It can be seen from the above embodiments that, the utility model is easy to use, and installation can be carried out using multiple types of tools and is torn open
It unloads, process is simple, greatly improves working efficiency.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all simply to modify or convert using made by the utility model description, it is relevant to be applied directly or indirectly in other
Technical field is also included in the patent protection scope of the utility model.
