Abstract
The utility mode relates a screw which can be rotated in two directions,which is a whole component comprising two column or conical screw members and an intermediate member of a regular polyhedron. Wherein,two screw members are rotated in two opposite directions, meanwhile length of diagonal of the regular polyhedron in middle portion is less than or equal to the maximum diameter of the screw members.By hiding inside two objects,the utility mode allows to connect and fasten two objects without gaps to achieve effect of overall aesthetic feeling.
Description
Affiliated technical field
The utility model relates to a kind of screw, can be hidden in two interior of articles, and can make the seamless connection of two articles and fastening.
Background technique
At present, the market nail pattern of tightening up a screw is more, does not but have and can two objects be carried out the screw that effective seamless butt joint is got up guarantee connecting under the prerequisite of overall appearance.Generally speaking, if want two object butt joints just must be reinforced outside, thereby caused the not attractive in appearance of the object of reinforcing.Declared by 4.1 classes in Daliang City, Liaoning Province red rock primary school, the patent No. is No. 200420066533.1 model utility, also effectively do not solve the seamless connectivity problem of two objects.
Summary of the invention
For overcome that two objects connect and tightly because of the time the not attractive in appearance and seamless problem in outside that causes, the utility model provides a kind of two-way screw, this two-way screw has not only solved the inaesthetic difficult problem that method such as reinforcing is outside brought, and has also solved the problem that makes two seamless connections of object and tighten up simultaneously.
The technological scheme that its technical problem that solves the utility model adopts is: two-way screw is designed to the screw rod that two ends are cylindrical body or cone, and is as a whole by the regular polygon connection of intermediate portion.Two screw flight sense of rotation of two-way screw are opposite, and defer to industrywide standard.The regular polygon catercorner length of intermediate portion is less than or equal to the maximum diameter of screw rod.
In shape, structure and combination thereof, the total essential features of two-way screw of the present utility model and immediate prior art is: the shape of screw rod and screw thread specification, and whole material all defers to industrywide standard, and all is to screw in object by screw rod to play and connect and fastening effect.The two-way screw of the present utility model technical characteristics different with immediate prior art is: the particular design of the regular polygon of two-way screw and cornerwise length restriction, fastening two objects that make this two-way screw easily (can use assistant tools such as spanner, pliers), after acquiring a certain degree, withdraw from spanner or pliers, again by rotating one of them object, can make the two-way screw be hidden in interior of articles, guarantee that two articles is in conjunction with whole attractive in appearance in back.Finally make the bigger object of two thickness (for two-way screw), perhaps the object that thickness is bigger and one can form an integral body by this connection and fastening mode, thereby reach seamless purpose of connecting than thin objects.
The beneficial effects of the utility model are: the one, and two objects of connection that can be seamless guarantee overall appearance; The 2nd, by particular design to the regular polygon of two-way screw intermediate portion, make connect or fastening two object processes in can use assistant tools such as spanner or pliers, work together convenient easily; The 3rd, two-way screw can make full use of all trades and professions such as precision assembling, family property production, building decoration, and not only convenient and swift but also attractive in appearance easy installation has greatly improved working efficiency and economic benefit; The 4th, simplicity of design is produced in enormous quantities easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model whole structure figure.
1. objects among the figure, 2. screw rod, 3. regular polygon, 4. screw rod, 5. object.
Embodiment
When needs connect object 1 and object 5, at first block regular polygon 3, make screw rod 2 screw in object 1 by rotary spanner or pliers, meanwhile with spanner or pliers, screw rod 4 screws in object 5, in screwing process, the slit that object 1 and object are 5 can be more and more littler, after acquiring a certain degree, withdraw from spanner or pliers, rotating object 1 or object 5 (selecting less one of object to be rotated) again until airtight fully, thereby reach the purpose of seamless connection object 1 and object 5.At this moment, two-way screw is hidden between object 1 and the object 5 all, thereby can not influence the attractive in appearance of integral body (combination of object 1 and object 5).
Because the screw rod 2 of two-way screw and screw rod 4 are and are threaded the cylindrical or conical of shape, it can be connected object 1 at an easy rate with fastening with object 5.Restriction by to the catercorner length of regular polygon 3 can make object 1 and 5 complete seamless connections of object, connects the attractive in appearance of object integral body thereby guaranteed two.By said method, realized the technological scheme of the seamless connection of two-way screw and fastening two objects.
Realize that the novel optimum scheme of this use is to be material with the iron and steel, the basic equipment that utilizes five metals to make processing factory is produced in batches, use for every profession and trades such as precision assembling, family property production, building decorations, thereby realize use value of the present utility model and economic value widely.
Claims (2)
1. two-way screw, screw portion by the intermediate portion of a regular polygon shape and two cylindrical bodys or cone shape is formed, it is characterized in that: the afterbody of two screw rods and the regular polygon of intermediate portion connect into an integral body, and two screw flight sense of rotation are opposite.
2. two-way screw according to claim 1 is characterized in that: the intermediate portion of two-way screw is a regular polygon, and its catercorner length is less than or equal to the maximum diameter of screw portion.
