Abstract
The utility model discloses a propelling pencil used for writing characters. The utility model adopts the structure that two spiricle grooves are arranged in a pencil tube of a common propelling pencil, both sides of a lead guard tube are slit, and a lead cap is additionally arranged in the tube. A cylindric lead cord is change into a prism structure. When a button is twisted, the lead guard tube is rotated to propel the prismatic lead cord out; due to the adoption of the structure, the phenomenon of the breakage of the lead cord can be effectively controlled.
Description
The present invention relates to a kind of writing implement, especially refer to by pen container, protect the propelling pencil that lead, button, lead for retractable pencil are formed.
At present commercially available common propelling pencil is exactly this structure, and it is cylindrical that it protects in the lead lead for retractable pencil, and is thin and have only i.e. one palm point of a constraint point.Depressing button when writing makes lead for retractable pencil free the constraint whereabouts.Above-mentioned situation very easily causes lead for retractable pencil disconnected broken, gives to write and makes troubles.
Task of the present invention provides a kind of propelling pencil that the disconnected broken situation of lead for retractable pencil is significantly improved.
For solving above-mentioned task, the solution that the present invention taked is: at first increase lead core diameter and make the lead for retractable pencil chap, just can effectively improve disconnected broken situation.Next is that lead for retractable pencil was controlled by having only a strong point to change into by two strong points originally.Also can effectively improve disconnected broken situation.
Cylindrical lead for retractable pencil overstriking meeting is given to write and is brought inconvenience, for this reason with lead for retractable pencil by the cylindrical prismatic structures that changes into.The lead core diameter that not only solved inconvenience but also overstriking improves the broken situation of resolving.
For making lead for retractable pencil that two strong points be arranged, method is: the pen container inwall at common propelling pencil is provided with two spiral lamination grooves, and plumbous cap, plumbous cap two ends are set in protecting lead has little knob to stretch out cracking from protecting the lead both sides, and embeds in the spiral lamination dimpled grain groove.Lead for retractable pencil one end is in plumbous cap like this, and the other end is protected the most advanced and sophisticated constraint of lead, reaches two strong points, thereby realizes that the present invention solves task.
Described button comprises two profile of tooth posts that are interlocked.One end with protect lead and link to each other, the other end stretches out pen container and makes press points outward.
Certainly button can also be a button identical with common propelling pencil.
Because such scheme just changes button into the profile of tooth post, lead for retractable pencil is changed into prismatic and increased plumbous cap, increases cost hardly on the whole by cylindrical, and reduced the lead for retractable pencil broken consumption of breaking effectively.
Below in conjunction with drawings and Examples present technique is described in further detail.
Fig. 1 is the longitudinal sectional drawing of one embodiment of the invention.
Fig. 2 is one of prismatic lead for retractable pencil structural representation
(cross section is an equilateral triangle)
Fig. 1 is the profilograph of a kind of propelling pencil of designing by the present technique principle.Pen container is formed with 2 companies of penholder by nib 1.Protect lead and flexibly connect, carefully hold 3 to be with spring 5 by butt end 4 and thin end 3 two parts, slightly thick in thin end 3 and written corresponding position, and endoporus is equilateral triangle, can freely open, by the nib constraint.Butt end 4 both sides are opened two seams and little knob on the plumbous cap 6 is stretched out and are embedded two spiral lamination grooves 7, and its spiral lamination is rotation in the same way, and begin to protect lead butt end 4 equal-height positions corresponding from penholder 2 silkings.Protecting lead links to each other with profile of tooth post 8 and must not relatively rotate.Topping tooth profile post 9 and pen container inwall have convex-concave mutually embedding make profile of tooth post 9 can only do upper and lower motion, and must not withdraw from by penholder 2 upper ends.Its part of stretching out pen container is with the plastic tube of loading onto rubber and does the button contact, and the double as rubber uses.Push rubber tip, lower end profile of tooth art 8 is rotated, and spring 5 is compressed simultaneously, protects the thin end 3 of lead and frees constraint.Thereby make and protect copper tube rotation and drive plumbous cap 6 and groove 7 in, move forward prismatic lead for retractable pencil release.This prismatic lead for retractable pencil is that cross section is the equilateral triangle lead for retractable pencil.
The design according to the present invention, button partly is not limited to two profile of tooth posts that are interlocked.Also can be the button of common propelling pencil, live button with hand during use and rotate then and can reach effect same.
Certainly above-mentioned prismatic lead for retractable pencil, also can be other prismatic lead for retractable pencil as: the cross section is " ten " font or " one " font lead for retractable pencil etc.
