Abstract
A connection type pencil of the utility model comprises a lead core and a wooden pole sleeved outside the lead core. At one end of the wooden pole, a screw structure connected with the wooden pole is arranged, and an external diameter of the screw structure is smaller than an external outline length of the wooden pole. At the other end of the wooden pole, a screw hole structure is arrange; the screw hole structure matches the screw structure; and the screw hole structure and the screw structure are concentric with the wooden pole. Two or more connection type pencils can be connected into a relatively long pencil through the screw hole structure and the screw structure, by using the connection type pencils of the utility model, so that it is convenient to write on a writing carrier which is relatively far away from the body or write a large character or symbol. Besides, the requirement of protecting the environment can be satisfied, by continuously using the connected left pencil stubs.
Description
Technical field
The utility model relates to a kind of pencil, particularly a kind of interconnection system pencil.
Background technology
Pencil be used to learn, the writing or draw tool of office, Graphing of Engineering, the fine arts, drawing, various marks etc., be most important stationery among the human lives.Common pencil length is fixed, on the nearer writing carrier of distance health, write not too big literal or symbol suits, but when writing carrier when the far away or literal that will write or symbol are very big apart from health, it is too short and inapplicable that existing pencil will seem, and common pencil is when becoming pencil stub with length finally is only remaining very short, remainder can't continue to use, and can cause the waste of resource, does not meet requirements of green environmental protection.
The utility model content
Be unsuitable for writing on distance health writing carrier far away in order to solve existing pencil, be unsuitable for writing too big literal or symbol, the problem with surplus pencil stub can't use the utility model proposes a kind of interconnection system pencil, and employed technical scheme is:
The interconnection system pencil, comprise lead for retractable pencil and the rod that is enclosed within the lead for retractable pencil outside, end at rod, screw-rod structure with the rod disjunctor is set, the external diameter of screw-rod structure is less than the exterior contour of rod, the other end of rod is provided with Screw hole structure, and Screw hole structure and screw-rod structure adapt, and Screw hole structure and screw-rod structure are coaxial with rod.
Interconnection system pencil, the section of rod are circular or 6 arris shapes, and the external diameter of screw-rod structure is less than the smallest radial size of circular outer diameter or 6 arris shapes.
Interconnection system pencil, the external diameter of screw-rod structure be the external diameter of circular cross section rod or 6 arris shape section rods the smallest radial size 1/2nd to 3/4ths.
Interconnection system pencil, the length of screw-rod structure are 1 times to 2 times of screw-rod structure diameter.
The interconnection system pencil, the screw thread of screw-rod structure is coarse plain thread, closely-pitched regular screw threads or tapered tread.
The interconnection system pencil, screw-rod structure is provided with escape.
The technique effect that interconnection system pencil of the present utility model adopts technique scheme to obtain is:
The interconnection system pencil, comprise lead for retractable pencil and the rod that is enclosed within the lead for retractable pencil outside, end at rod, screw-rod structure with the rod disjunctor is set, the external diameter of screw-rod structure is less than the exterior contour of rod, the other end of rod is provided with Screw hole structure, Screw hole structure and screw-rod structure adapt, 2 or more interconnection system pencils can be connected into long pencil by Screw hole structure and screw-rod structure, conveniently on distance health writing carrier far away, write, or write very big literal or symbol, can also use too shortly at pencil, when inconvenience grips, will be screwed on the new pencil with surplus pencil stub, or be connected with another pencil stub, strengthen the length of pencil stub, the convenient use avoids waste, and satisfies requirements of green environmental protection.Screw hole structure and screw-rod structure are coaxial with rod, can make the profile after many interconnection system pencils connect smooth smooth, are beneficial to grip and use.
Interconnection system pencil, the section of rod are circular or 6 arris shapes, and the external diameter of screw-rod structure can guarantee that less than the smallest radial size of circular outer diameter or 6 arris shapes screw-rod structure and Screw hole structure do not destroy the structure and the profile of rod.
The interconnection system pencil, the external diameter of screw-rod structure be the external diameter of circular cross section rod or 6 arris shape section rods the smallest radial size 1/2nd to 3/4ths, can make screw-rod structure and Screw hole structure under the prerequisite of the structure of not destroying rod and profile, have reliable switching performance.
Interconnection system pencil, the length of screw-rod structure are 1 times to 2 times of screw-rod structure diameter, can guarantee switching performance, the bonding strength of screw-rod structure and Screw hole structure, and cut down finished cost.
The interconnection system pencil, the screw thread of screw-rod structure is coarse plain thread, closely-pitched regular screw threads or tapered tread, can make things convenient for the design and the manufacturing work of interconnection system pencil, reduces cost.
The interconnection system pencil, screw-rod structure is provided with escape, is convenient to screw-rod structure is all screwed in the Screw hole structure, improves bonding strength, the convenient use.
Use interconnection system pencil of the present utility model, can make things convenient for and write at a distance or the writing of very big literal and symbol, can satisfy requirements of green environmental protection using with continuing behind the surplus pencil stub spreading.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model interconnection system pencil.
Sign implication in the accompanying drawing is as follows:
The 1-lead for retractable pencil, 2-rod, 3-screw-rod structure, 4-Screw hole structure, 5-escape.
The specific embodiment
Interconnection system pencil of the present utility model, structure as shown in Figure 1, comprise lead for retractable pencil 1 and the rod 2 that is enclosed within lead for retractable pencil 1 outside, end at rod 2, the screw-rod structure 3 of setting and rod 2 disjunctors, the external diameter of screw-rod structure 3 is less than the exterior contour of rod 2, and the other end of rod 2 is provided with Screw hole structure 4, Screw hole structure 4 adapts with screw-rod structure 3, and Screw hole structure 4 and screw-rod structure 3 are coaxial with rod 2.
The section of rod 2 is circular or 6 arris shapes, and the external diameter of screw-rod structure 3 is less than the smallest radial size of circular outer diameter or 6 arris shapes.
The external diameter of screw-rod structure 3 be the external diameter of circular cross section rod 2 or 6 arris shape section rods 2 the smallest radial size 1/2nd to 3/4ths.
The length of screw-rod structure 3 is 1 times to 2 times of screw-rod structure 3 diameters.
