Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force that utilize object, is fastened by easy stages
The instrument of implements parts, screw is the general saying of fastener, and daily pet phrase, screw is work indispensable in daily life
Industry necessity：The minimum screw that such as camera, glasses, clock and watch, electronics are used；TV, electric product, musical instrument, furniture etc.
General screw；Large-scale screw, nut are then used as engineering, building, bridge；Traffic tool, aircraft, electric car, automobile etc. are then
It is used in combination for big primary screw, screw industrially bears vital task, as long as there is industry on the earth, then the function of screw is eternal
Important, still, current screw is in use because stiffness issue can not bore iron plate, and rust-preventing characteristic is bad, and service life is short.
The content of the invention
The purpose of this utility model is the bimetallic screw for providing a kind of high rigidity, and iron plate can be bored by possessing hardness height,
The good and easy to use advantage of rust-preventing characteristic, solves current screw in use because stiffness issue can not bore iron plate, and
And rust-preventing characteristic is bad, the problem of service life is short.
To achieve the above object, the utility model provides following technical scheme：A kind of bimetallic screw of high rigidity, including
Screw head, the bottom of the screw head is fixedly connected with fixed plate, and the bottom of the fixed plate is fixedly connected with screw rod, the screw rod
Surface offers thread groove, and the surface loop of the screw rod is around offering the chip area that is connected with thread groove, the screw rod front surface
Bottom and back surface bottom offer connected with thread groove enter to consider to be worth doing groove, the bottom of the screw rod front surface and back surface
Bottom be fixedly connected with projection.
It is preferred that, the screw head is shaped as hexagon.
It is preferred that, it is socketed with pad at the top of the screw surface.
It is preferred that, open up fluted at the top of the screw head.
It is preferred that, the bottom of the screw head is fixedly connected by fixture with fixed plate.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is by setting screw head, screw rod and projection, and can increase to the hardness of screw can bore iron plate
Degree, and by screw head and screw rod fusion when use cold-welding technique and laser cold-welding technique, can be significantly
The rust-preventing characteristic of the screw is improved, service life is long.
2nd, the utility model is by setting into bits groove and chip area, and can be screwed into screw in user needs fixed material
Scrap is discharged during material, it is to avoid scrap excessively causes the problem of screw easily loosens, by setting pad, by increasing capacitance it is possible to increase screw
Stability, by setting groove, can convenient use person by instrument fit by screw tightening.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model structure top view.
In figure：Groove, 6 projections, 7 pads, 8 grooves, 9 fixed plates are entered to consider to be worth doing in 1 screw head, 2 screw rods, 3 thread grooves, 4 chip areas, 5.
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
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, belongs to the scope of the utility model protection.
Fig. 1-2, a kind of bimetallic screw of high rigidity, including screw head 1 are referred to, the top of screw head 1 opens up fluted 8,
By setting groove 8, can convenient use person by instrument fit 8 by screw tightening, screw head 1 is shaped as hexagon,
By screw head 1 be shaped to hexagon can with convenient use person by instrument by screw tightening, the bottom of screw head 1 is fixedly connected
There is fixed plate 9, the bottom of fixed plate 9 is fixedly connected with screw rod 2, and screw head 1 is stainless steel, and screw rod 2 is steel alloy material, mesh
Be that instead of 304 models and cannot bore the effect of iron plate, more preferable antirust is served again, is used when screw head 1 and screw rod 2 are merged
Technology be cold-welding technique and laser cold-welding technique, antirust salt fog was up to 4000 hours, and outdoor can be used more than 50 years, screw head 1
Bottom be fixedly connected by fixture with fixed plate 9, screw rod 2 is socketed with pad 7 at the top of surface, because pad 7 is not flat
, being flattened by extruding, generation is elastic, and the friction applied on the connector of screw between an axial force, increase screw thread reaches
Anti-loosing effect, by setting pad 7, by increasing capacitance it is possible to increase the stability of screw, the surface of screw rod 2 offers thread groove 3, screw rod 2
Surface loop is around the chip area 4 that is connected with thread groove 3 is offered, and the bottom of the front surface of screw rod 2 and the bottom of back surface are offered
What is connected with thread groove 3 enters to consider to be worth doing groove 5, by setting into bits groove 5 and chip area 4, and can be screwed into screw in user needs admittedly
Scrap is discharged during fixed material, it is to avoid scrap excessively causes the problem of screw easily loosens, the bottom of the front surface of screw rod 2 and the back of the body
The bottom on surface has been fixedly connected with projection 6, by setting screw head 1, screw rod 2 and projection 6, can increase to the hardness of screw
The degree of iron plate can be bored, and cold-welding technique and laser cold-welding technique, energy are used when screw head 1 and screw rod 2 are merged
Enough rust-preventing characteristics for significantly improving the screw, service life is long.
In use, because screw head 1 is stainless steel, screw rod 2 is steel alloy material, can bore iron plate and can be fine
Antirust, service life is long.
In summary：The bimetallic screw of the high rigidity, by screw head 1, screw rod 2, thread groove 3, chip area 4, enters to consider groove to be worth doing
5th, projection 6, pad 7 and groove 8, solve current screw in use because stiffness issue can not bore iron plate, and antirust
Bad, the problem of service life is short of property.
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 in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
