Abstract
The utility model discloses a propelling pencil with continuous cores, which is suitable for using the cores whose diameters are below 0.7 mm. The utility model solves the problem that the existing propelling pencil with fine cores can not be continuously used, the press times are many, the cores is retained, and the cores are easy to be broken. The utility model is characterized in that the end of the core protecting tube is provided with a damping to make the cores close to the paper when being blocked, and the propelling pencil with continuous cores can write by only pressing one time.
Description
The utility model relates to a kind of improved propelling pencil.
Existing thin propelling pencil mainly by retaining core pipe, damping rubber circle, Movable loop, folder plumbous pawl, spring, core storage tube, envelope is emitted and penholder is formed.Its occupation mode is a pulsating, and promptly lead for retractable pencil is packed into needs behind the core storage tube pressing envelope to emit 10～25 times lead for retractable pencil to be exposed, just can write.When first lead for retractable pencil used the plumbous pawl of folder and can't clip, rebound phenomenon appearred in lead for retractable pencil, can't continue to write.Need once more the pressing envelope to emit 10～25 times, second lead for retractable pencil just can eject the residual lead for retractable pencil of first lead for retractable pencil.The residual lead for retractable pencil that ejects is thrown away, and is so not only time-consuming but also take lead for retractable pencil.
In order to overcome above-mentioned defective, the utility model will provide a kind of pressing once can write and the propelling pencil of residual lead for retractable pencil not.
Operation principle is: have one can be up and down retaining core pipe, at the plumbous end of going out of retaining core pipe to the lead for retractable pencil damping.Downwards lead for retractable pencil and retaining core pipe descend simultaneously during pressing, and lead for retractable pencil is obstructed and stops.Because damping is located at the end of pen, so lead for retractable pencil just can drop to the tip of the brushstyle of a writing or painting.Again because the retaining core pipe activity, thus the tip of the brushstyle of a writing or painting one contact paper, retaining core pipe slightly bounces back, and lead for retractable pencil will contact paper rapidly, can write.Along with shortening gradually of last lead for retractable pencil, a back lead for retractable pencil can be followed out automatically, uses up up to last lead for retractable pencil.
The utility model is because adopted the mode of tip of the brushstyle of a writing or painting damping, so can not occur because the too short and out of use phenomenon of lead for retractable pencil.Make lead for retractable pencil reach the effect that uses up continuously.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.
Fig. 2 is that Fig. 1 goes out the plumbous part amplification view of economizing plumbous propelling pencil continuously.
With reference to Fig. 1, movable retaining core pipe (3) that damping thing (2) arranged in the end is contained in the recreation room (4) and keeps smooth contact, and recreation room (4) links to each other with penholder (8) by holes for clamping (5).When firmly the pressing envelope is emitted (10) downwards, pressing from both sides plumbous pawl (6) opens by elasticity, movable retaining core pipe (3) is reduced to extreme lower position, and the lead for retractable pencil (1) in the storage lead pipe (9) will descend rapidly under the effect of gravity, during chance activity retaining core pipe (3) end damping thing (2) and stop.After removing envelope and emitting pressure on (10), press from both sides plumbous pawl (6) and under the effect of spring (7), set back and clamp lead for retractable pencil (1).In writing process, lead for retractable pencil (1) contacts paper simultaneously with movable retaining core pipe (3), and along with the wearing and tearing of lead for retractable pencil (1), movable retaining core pipe (3) will rise gradually, when movable retaining core pipe (3) rises to holes for clamping (5), finishes once and writes.Firmly pressing once seals and emits (10) can finish above-mentioned action again then, writes next time.
Claims (1)
- One by damping thing (2), movable retaining core pipe (3), recreation room (4), holes for clamping (5), press from both sides that plumbous pawl (6), spring (7), penholder (8), core storage tube (9) and envelope emit that (10) form go out the plumbous plumbous propelling pencil of economizing continuously, it is characterized in that the plumbous end of going out of movable retaining core pipe (3) inwall has damping thing (2).
