Description
[technical field]
The utility model relates to be write or the drawing appliance technical field, specifically a kind of rod or plastic bar or Metallic rod full automatic pencil.
[background technology]
China is Wood-bar pencil big producing country, and the output of last year is up to 15,000,000,000, but the real data this and more.In the output sum, wherein be to export to abroad mostly 80%.And for protecting forest resources; there is planning in external a lot of country to the use of forest; the output of restriction Wood-bar pencil; Chinese then the resource that consumes in a large number the descendants for foreign exchange; timber relevant department in short supply is appealed more than ten years; fail but to cause that everybody notes, Wood-bar pencil output is still in continuous rising.Thousands of people is also constantly sharpening a pencil, and contaminated environment is destroyed forest, and thought that unconsciously with the pencil sharper pencil be right and proper, also continually develops pencil sharpener.
Pencil has the centuries historical, has and easily writes and be easy to erasing out handwriting, is beneficial to student's exercise, the usefulness of working out a draft or draw, although promoted out erasable ball pen, gel ink pen afterwards, does not all replace pencil.The human culture development of developing into of pencil has played great role, and pencil also be each child just learn to write must use writing implement.But nib can chap in use for some time for pencil, at this moment just needs to sharpen a pencil, sometimes write tens words and just will repair and cut core, even and also can't guarantee like this to write the consistent of handwriting thickness fully, use inconvenient.Also have a kind of thin propelling pencil in the prior art, repair after its relatively common Wood pencil compares environmental protection and need not to write a period of time and cut.But propelling pencil also has its deficiency, such as easily broken core, often press to adjust and reveal core length, and because there is certain limitation in it, lower pupil can not use.
And full automatic pencil of the prior art is non-sharpenning, need not write by kinetic energy always.But current auto-compensation pencil can be divided into full-automatic propelling pencil and full automatic pencil.Wherein, full-automatic propelling pencil has the repertoire of the thin propelling pencil of pulsating, sandwich, Chu Xin, send core, press and once send one section core, write line weight unanimously without the advantage of core finishing, it is the sandwich parts of auto-compensation and draw core components to introduce in the propelling pencil, has in writing the lead for retractable pencil that need not be worn by the kinetic energy auto-compensation, until a lead for retractable pencil is finished, can not write to press and affect thinking because exposing lead for retractable pencil.But the same propelling pencil of this series products outward appearance very easily confuses the general activity pencil.This product is fit to the adult to be used, and outward appearance can have various forms, is fit to user's selection.The upgrading products of propelling pencil.But the pen that goes out lead for retractable pencil by kinetic energy is difficult for grasping, and school stipulates that lower pupil can not use; And another kind of full automatic pencil, its outward appearance resembles pencil, in only have a lead for retractable pencil, can only write, lead for retractable pencil can come out to a lead for retractable pencil always and be finished, and can not press, and is non-sharpenning, is fit to the primary grades pupil and uses.But in only have a lead for retractable pencil, lead for retractable pencil is finished and nib need to be extracted, and manually a lead for retractable pencil is pushed into chuck.Change difficulty of core, to change core easy not as propelling pencil.
[summary of the invention]
The purpose of this utility model is exactly to provide a kind of novel structure in order to solve deficiency of the prior art and defective, a kind of rod full automatic pencil of easy to use and environmental protection.
For achieving the above object, design a kind of rod full automatic pencil, comprise and draw core components, the sandwich parts, send core components and afterbody part, it is characterized in that being provided with thin-wall metal bushing in the described sandwich parts, be provided with cavity in the described thin-wall metal bushing; be provided with circular hole in the middle of the thin-wall metal bushing bottom; the thin-wall metal bushing bottom periphery is provided with push rod work limited block; described thin-wall metal bushing top is provided with and connects the spiral shell parts; the described spiral shell parts endoporus that connects is provided with step; connect the spiral shell component top and draw the point cover in the core components to be connected; send that push rod one end cooperates with the hole interference activity of sandwich parts liner in the core components; and be subjected to inner side limiting-position at the bottom of the thin-wall metal bushing hole; be provided with spring and core storage tube outside the push rod, spring one end withstands the thin-wall metal bushing rear end face, and the spring other end withstands core storage tube one end; core storage tube is provided with wooden penholder outward, join with wooden penholder glue outside the thin-wall metal bushing and be connected.
Gluedd joint with rod the positioning pipe bottom after described afterbody part comprised rear positioning pipe, tail cap, rubber seat and rubber, and core storage tube afterbody end in the pore of rear location is connected with rubber with the rubber seat, and described rear positioning pipe, rubber seat and rubber are arranged in the tail cap.
Reaming is carried out at described wooden penholder two, and the thin-wall metal cover is arranged at the front hole of wooden penholder, and rear positioning pipe is arranged in the wooden penholder metapore.
Be provided with intermediate plate and steel ball in the described sandwich parts, with clamp ring, spring, the liner composition brake of the quoit conical surface, lead for retractable pencil only export but no import, described sandwich parts cooperate at the thin-wall metal bushing internal clearance.
Described point cover profile is the step cone structure, and connects the spiral shell parts and is connected, and the interior retaining core pipe of point cover is provided with damping, and retaining core pipe has spring and back-up ring outward.
Described push rod and core storage tube close-fitting, spring are arranged between thin-wall metal bushing and the core storage tube, and one of thin-wall metal bushing and the hole interference activity of sandwich parts liner are connected.
Described wooden penholder is that the plane is connected or the inclined-plane connects or cambered surface connects with the junction of tail cover parts or is connected with a joggle.
The utility model has overcome can not pack into defective in the standard rod of full automatic pencil machine core in the prior art, compare with prior art, a kind of brand-new rod full automatic pencil is provided, solved movement this key technology in the rod of packing into, and emphasis core apparatus technique effect of the present invention is obviously outstanding.Outward appearance of the present utility model is similar to the pencil shape, can make using the colony of pencil more acceptant, but its in use non-sharpenning, need not press, can constantly write, therefore have again the advantage of full automatic pencil concurrently.When lead for retractable pencil is finished, only need unplug the tail cap, can press knockout, convenient as propelling pencil, the hand of in changing the core process, can not making dirty, and the series of products of 0.7,0.5 millimeter specification are arranged, satisfy different personnel's instructions for use, the particularly use of student's pencil, applied widely and environmental protection is practical.
