Abstract
The utility model discloses a pencil that can be used repeatedly for writing, belonging to a technical field of pencil manufacturing. The utility model is characterized in that a lead core positioning guide hole, a tapered locking hole and an internal thread fastening hole are arranged in the inner cavity of pencil point ; a lead core locking section and an external thread fastening section are arranged on the outer circle of the end of pencil barrel with lead core middle hole; a notch is arranged on the outer circle of the lead core fastening section along center line direction; the tapered locking hole and the internal thread fastening hole of the inner cavity of pencil point are respectively connected with the lead core locking section and the external thread fastening section of the outer circle of the end of pencil barrel; the lead core positioning guide hole of pencil point is corresponding to the center position of the lead core middle hole of pencil barrel. The reduction of parts of pencil body eliminates the coaxiality error resulted from excessive combined parts in the lead core of the prior pencil body so as to realize reliability, stability and no looseness of lead core and improvement of writing quality, thereby reducing the breaking of lead core and having convenient use.
Description
Technical field:
The utility model relates to pencil manufacturing technology field; Be specifically related to a kind of reusable pencil.
Background technology:
Reusable pencil in the prior art is to be connected and composed by nib, fairlead, dop and four single part of penholder; Exist not enough: the one, complex structure, many handwriting lead for retractable pencil mesopores that single part constitutes easily form coaxiality deviation, cause lead for retractable pencil to tighten up poor stability, and lead for retractable pencil is easily loosening during writing words, has directly influenced the quality of writing font; The 2nd, influenced by the coaxiality deviation of four single part, be fastened at the lead for retractable pencil unbalance stress in the handwriting, frangibility in writing the font process needs often to change lead for retractable pencil, uses inconvenient.
Summary of the invention:
Above-mentioned technical problem to be solved in the utility model, the one, many single part combined connecting structure complexity, it is unreliable stable that the coaxiality deviation of generation causes lead for retractable pencil to tighten up, easily loosening, influences the quality that font is write; The 2nd, be subjected to the influence of handwriting lead for retractable pencil mesopore coaxiality deviation, cause lead for retractable pencil to be fastened at unbalance stress in the handwriting, frangibility when writing font is used inconvenient.
The utility model is to comprise nib and penholder for solving the problems of the technologies described above technical scheme to be solved; Its improvement is: at hollow form nib inner chamber, be respectively equipped with lead for retractable pencil positioning guide hole, circular cone locking hole and internal thread and tighten up the hole; On the penholder one end end cylindrical that is provided with the lead for retractable pencil mesopore, be respectively equipped with lead for retractable pencil locking section and the external screw thread section of tightening up; Described on the lead for retractable pencil section of tightening up cylindrical, be provided with three open slots at least along its centerline direction; The circular cone locking hole and the internal thread of described written inner chamber tighten up the hole, respectively with the pen arm end cylindrical on lead for retractable pencil locking section and the external screw thread section of tightening up be connected; The written lead for retractable pencil positioning guide hole that is connected is corresponding with penholder lead for retractable pencil mesopore center.
The utility model is taked technique scheme, respectively the lead for retractable pencil positioning guide hole is located at written inner chamber and lead for retractable pencil is locked section and be located on the pen arm end cylindrical, by written internal thread and externally threaded being threaded of penholder are tightened up, make the circular cone locking hole that places written inner chamber lock section and closely contact cooperation, reached tightening up lead for retractable pencil with the lead for retractable pencil on the cylindrical of written end; Four single part of the prior art are simplified to nib and two single part of penholder, and the handwriting part is few, and compact conformation has been eliminated the coaxiality error that original handwriting lead for retractable pencil mesopore is connected and causes because of many single part.Realized that lead for retractable pencil tightens up firm stable and do not become flexible, written word physique amount improves; Reduced lead for retractable pencil frangibility phenomenon, easy to use.
Description of drawings:
Fig. 1 is the utility model cut-away section front view;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the cutaway view of nib;
Fig. 4 is the partial sectional view of penholder.
The specific embodiment:
Fig. 1-shown in Figure 4.This reusable pencil comprises nib and penholder; Be at hollow form nib inner chamber, be respectively equipped with lead for retractable pencil positioning guide hole 5, circular cone locking hole 6 and internal thread and tighten up hole 7.On the penholder one end end cylindrical that is provided with lead for retractable pencil mesopore 10, be respectively equipped with lead for retractable pencil locking section 8 and the external screw thread section of tightening up 9; On the described lead for retractable pencil section of tightening up 8 cylindricals, be arranged with four open slots 3 (shown in Figure 2) along its centerline direction.The circular cone locking hole 6 and the internal thread of described written inner chamber tighten up hole 7, respectively with the pen arm end cylindrical on lead for retractable pencil locking section 8 and the external screw thread section of tightening up 9 be connected; The written lead for retractable pencil positioning guide hole 5 that is connected is corresponding with penholder lead for retractable pencil mesopore 10 centers.During use, usually selecting lead core diameter is 2mm, rotating nib unclamps its internal thread and penholder external screw thread, lead for retractable pencil locking section 8 on this moment penholder leading section cylindrical disengages with circular cone locking hole 6 surfaces of written inner chamber and cooperates, the penholder lead for retractable pencil locking section 8 that is provided with open slot 3 increases by its strain outside diameter expansion, lead for retractable pencil mesopore 10 diameters of its clamping lead for retractable pencil 1 also increase thereupon, people can adjust the length of required lead for retractable pencil 1 external part of written word body, screw nib again and cooperate with the internal and external screw thread of penholder.Also make simultaneously the circular cone locking hole 6 surperficial subtend contact extruding of the lead for retractable pencil locking section 8 end cylindricals of penholder along written inner chamber, lead for retractable pencil locking section 8 outside diameter strains are dwindled, lead for retractable pencil 1 card in its lead for retractable pencil mesopore 10 is firmly tight with placing.As required, can also be connected with erasing rubber 2 in the other end end of penholder.
