Description
Technical field
It the utility model is related to screw technical field, and in particular to a kind of screens screw.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The instrument of implements parts.Screw is the general saying of fastener, daily pet phrase.Screw is work indispensable in daily life
Industry necessity：The minimum screw that such as camera, glasses, clock and watch, electronics use；TV, electric product, musical instrument, furniture etc.
General screw；As for engineering, building, bridge then using large-scale screw, nut；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
It is important.Screw is the joint invention in people's production and living over the past thousands of years, and from the point of view of application field, it is the first big of the mankind
Invention.
But although existing screw can meet the effect for connecting securing objects, when being screwed into installation, it is impossible to directly
Turned with hand, made troubles to use；The outer peripheral face of screw rod is outside nut entirely simultaneously, and then increases the friction between screwed hole
Power, also just accordingly improve the difficulty being screwed into；And it is that something or somebody to fall back on portions are pressed on object, the work(without suspension or tied rope
Energy.If being only to be screwed into a part without tightening, easily occur releasing phenomenon because of vibrations.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, rationally, be easily installed,
And the screens screw firmly installed.
To achieve the above object, technical scheme provided by the utility model is：
A kind of screens screw, it includes the body of rod and the head being connected with the body of rod, the spherical projection of top surface on the head
Shape, the end face center on the head are provided with cross recess, the left and right ends linear extension of the cross recess and the side wall for running through the head,
The outer peripheral face on the head is provided with anti-slop serrations, and one end that the body of rod is connected with head is radially enlarged to form screens step, should
The middle part of the body of rod, which radially reduces, forms connecting portion, the radially enlarged formation department of assembly of the other end of the body of rod, the diameter of the department of assembly
Less than the diameter of screens step, the department of assembly is provided with external screw thread.
As a kind of improvement of the present utility model, the body of rod and head are integrated attachment structure, are connected firmly, and structure is steady
It is qualitative good.
As a kind of improvement of the present utility model, its off-balancesheet face is electroplate with color zinc layers, then makees dehydrogenation 6h processing, effectively
Lift wearability and alkali resistant acid-resisting.
The beneficial effects of the utility model are：Smart structural design of the present utility model, rationally, the top surface on head is spherical
Convex, on the basis of enhancing structure intensity, without rude sense, avoid scraping and hurt sb.'s feelings or thing；The outer peripheral face on head is provided with
Anti-slop serrations, it is convenient directly to be turned with hand, brought convenience to installing and using；Provided with screens step so that when tightening locking, head
There is certain spacing from locking object, can be used for suspension or the sub- purposes of tied rope, while the middle part of the body of rod radially reduces the company of being formed
Socket part, do not contacted with screwed hole, on the basis of bonding strength is ensured, reduce frictional force, further facilitate installation, while also save
Material saving, cost is reduced, overall structure is simple, compact in addition, it is easy to accomplish, it is easy to be widely applied.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is side structure schematic view of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of screens screw of the present embodiment offer, it includes the body of rod 2 and is connected with the body of rod 2
Head 1, the spherical convex of top surface on the head 1, the outer peripheral face on head 1 is provided with anti-slop serrations 11, convenient directly to be twisted with hand
It is dynamic, brought convenience to installing and using；The end face center on the head 1 is provided with cross recess 12, the left and right ends straight line of the cross recess 12
The side wall on the head 1 is extended through, goes for cross tool heads or a word tool heads, it is applied widely.
The outer peripheral face on head 1 is provided with anti-slop serrations 11, convenient directly to be turned with hand, is brought convenience to installing and using.It is described
The radially enlarged formation screens step 21 in one end that the body of rod 2 is connected with head 1, provided with screens step 21 so that tightening locking
When, there is certain spacing on head 1 from locking object, can be used for suspension or the sub- purposes of tied rope, function are more.
The middle part of the body of rod 2, which radially reduces, forms connecting portion 22, that is, is being threaded into the inwall of the Kong Shiyu screwed holes
