Abstract
The utility model relates to a propelling pencil with a rotating nib, which is composed of a pencil holder, a pencil head, a spiral tube and a leading block. The upper part of the pencil head which is connected with the pencil holder are provided with two tubular round lug bosses with a big diameter and a small diameter, the big lug boss is provided with an axial opening where the pencil head and the pencil holder are connected, one end of the spiral tube is arranged on the tail part of the pencil head, the other end is provided with the leading block, and the leading block is used for making the lead core advance and retreat by rotating the pencil head. The technical proposal can avoid the defect of easily breaking the lead core, and the utility model is suitable for various occasions. The utility model has the advantages of easy assembly, low cost, easy use, reliable writing, and comfortable writing feeling.
Description
The utility model relates to a kind of propelling pencil.
Plumbous formula propelling pencil is advanced in general rotation at present, mostly come to advance before and after the transmission lead for retractable pencil by a rotation tail, the propelling pencil of this kind form not only is easy to generate the lead for retractable pencil situation that fractures during ubiquity advance and retreat lead for retractable pencil, and rocks the lead for retractable pencil that fractures equally easily because of lead for retractable pencil when writing.Chinese patent 92202043.4 discloses a kind of " multifunctional propelling pencil ", promptly be to make the propelling pencil of advancing before and after the lead for retractable pencil by the rotation nib, though can solve above-mentioned existing drawback, the boss that its nib of showing, the penholder form of interconnecting are depended merely on separately is to be difficult to assembling.
The purpose of this utility model provides a kind of rotation nib formula propelling pencil that can overcome above-mentioned technical deficiency part.
The purpose of this utility model realizes in the following manner: by penholder, nib, the rotation nib formula propelling pencil that helix tube and helical pitch piece are formed, having respectively greatly on nib with the penholder connecting portion, two tubular circular boss that minor diameter is different, on big boss, axially open is arranged, the natural elasticity that axially open is produced when being connected with penholder for nib makes its nib, penholder is connected, one end of helix tube is installed in the tubular circular boss pipe on the nib, its other end is equipped with the helical pitch piece, by rotating nib its revolving force is acted on the helix tube, the helical pitch piece transmission lead for retractable pencil work that then is contained on the helix tube is axially advanced front and back, can use.
The utility model only needs revolving force is acted on the drawback of the lead for retractable pencil of can avoiding on the nib fractureing easily; Structure simultaneously that the structure on its nib is easy and in the penholder matches, can reach the effect of being convenient to assemble, rotate freely, and nib, penholder and other parts all adopt injection molded one time, avoided secondary reprocessing, so greatly reduce cost of manufacture.The assembling simple in structure, easy of this utility model, easy to use and reliable, cost of manufacture is cheap, lead for retractable pencil turnover is accurately write and is felt comfortable, it is applicable to 0.5-2.0 millimeter all size lead for retractable pencil, is a kind of propelling pencil that multiple occasion is used that is fit to.
Figure of description 1 is a structural representation of the present utility model;
Figure of description 2 is the structural representation of nib of the present utility model, penholder company headquarters position.
In conjunction with the embodiments the utility model is described in further detail with reference to Figure of description.
The written formula propelling pencil of rotation of the present utility model, be by penholder (6), nib (3), helix tube (4) and helical pitch piece (5) are formed, having respectively greatly on nib (3) with penholder (6) coupling part, two tubular circular boss (D) that minor diameter is different, (A), on big boss (D), axially open (E) is arranged, on big boss (D) surface, be provided with plural axial ribs, axial ribs is sloping shape by high position (B) to lower position (C), the front end inboard of penholder (6) has and the big or small tubular circular boss (D) of nib on (3), (A) step that matches, plural helical pitch muscle (7) is arranged in the penholder (6), one end of helix tube (4) is installed in interior nib (3) the tubular circular boss pipe of penholder (6), the other end of helix tube (4) is equipped with helical pitch piece (5), the chute that matches with the interior helical pitch muscle of penholder (6) (7) is arranged on the helical pitch piece (5), the inboard front end of nib (3) is equipped with damped ring (2), and lead for retractable pencil (1) passes on the helical pitch piece (5) that is contained in the nib (3) in the penholder (6).
Make when using, nib (3), penholder (6), helical pitch piece (5) adopt single injection-molded.Nib (3) Inner Front End of earlier rubber damping circle (2) being packed into during assembling goes out place, plumbous hole, helix tube (4) is packed in the tubular circular boss pipe of nib (3) rear end, pack into after then can axially open (E) compressing with nib (3) rear end tubulose round boss pipe front end of penholder (6) matches it.Can insert employed lead for retractable pencil (1) opening part of helical pitch piece (5) this moment, opening a tail packs lead for retractable pencil in the pen into, after rotation nib (3) matched the interior helical pitch muscle (7) of chute and the penholder (6) on the helical pitch piece (5), the transmission lead for retractable pencil was advanced, is retreated, and covering a tail can use.Tail is that prior art no longer repeats to give unnecessary details here.
