At nib and send between the core pipe and be provided with guide rail, the front end of guide rail is connected with nib by the knockout spring, and the rear end of guide rail is inserted in and is sent the core pipe, send the not end of core pipe to slide in guide rail, and guide rail is provided with lock core mechanism by in the end of nib.
Described lock core mechanism includes clamp ring, steel ball, intermediate plate and support spring, it is cone that the clamp ring outside is the cylinder internal diameter, place the intermediate plate of two half-cylinders in this clamp ring, one ball pit is arranged on the exterior arc surface of intermediate plate and place steel ball, front end sleeve one support spring at two intermediate plates, the other end of support spring closes up with guide rail and contacts, and clamp ring is set in the guide rail.
The described core mechanism that send is formed by connecting spring and guide pipe, and guide pipe places the interior rear end of guide rail and contacts with sending the core pipe end, connects spring at the guide pipe overcoat, and the other end of this connection spring contacts with clamp ring.
Send an end of core barrel to be inserted in end in the guide rail, send the other end of core pipe to be connected with core storage tube, sending the interior end of core pipe is wide pipe, and an end is narrow pipe, and wide pipe is connected for the funnel type transition with narrow pipe, and narrow pipe end is communicated with guide pipe, and wide pipe end is communicated with core storage tube.Send the core pipe to be with outward and send the core spring, this send the other end of core spring to contact with rail end.
Example with accompanying drawing is further described the utility model below:
The drawing explanation
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of mechanical type automatic propelling pencil that the utility model provides, pinching parts such as 12 by nib 1, nib 2, penholder 15, hand forms, be provided with successively in the penholder 2 and lift cap (not shown), core storage tube 16, send core pipe 13, send core mechanism and lock core mechanism, it is characterized in that: in nib 2, be provided with the knockout mechanism that forms by nib 1, damping 3 and knockout spring 4, damping 3 is set in the nib 1 inner centre bore for rubber, and knockout spring 4 is enclosed within on the external diameter of nib 1 the inner.
At nib 1 and send and be provided with guide rail 9 between the core pipe 13, the front end of guide rail 9 is connected with nib 1 by knockout spring 4, the rear end of guide rail 9 is inserted in and is sent core pipe 13, send the not end of core pipe 13 can longitudinal sliding motion in guide rail 9, and guide rail 9 is provided with lock core mechanism by in the end of nib 1.
Described lock core mechanism includes clamp ring 7, steel ball 6, intermediate plate 8 and support spring 5, it is cone that clamp ring 7 outsides are the cylinder internal diameter, place the intermediate plate 8 of two half-cylinders in this clamp ring 7, one ball pit is arranged on the exterior arc surface of intermediate plate 8 and place steel ball 6, front end sleeve one support spring 5 at two intermediate plates 8, the other end of support spring 5 closes up with guide rail 9 and contacts, and clamp ring 7 is set in the guide rail 9.
The described core mechanism that send is formed by connecting spring 10 and guide pipe 11, guide pipe 11 place in the guide rail 9 rear ends and with send the core pipe 13 end in contact, at guide pipe 11 overcoats connection spring 10, the other end of this connection spring 10 contacts with clamp ring 7.
Send an end of core barrel 13 to be inserted in the guide rail 9 terminal, send the other end of core pipe 13 to be connected with core storage tube 16, sending core pipe 13 interior ends is wide pipe, one end is narrow pipe, wide pipe is connected for the funnel type transition with narrow pipe, and narrow pipe end is communicated with guide pipe 11, and wide pipe end is communicated with core storage tube 16, send core pipe 13 outer being with to send core spring 14, this send the other end of core spring 14 to contact with guide rail 9 ends.
Operation principle:
When writing, the end of the lead for retractable pencil 17 in the automatic propelling pencil contacts with paper, with moving of beginning to write, lead for retractable pencil 17 constantly is worn away when shortening, nib 1 also contacts paper and the upward pressure when being write and up moving simultaneously, displacement equals lead for retractable pencil 17 abrasion length, and knockout this moment spring 4 also compresses this distance.Can make frictional force of generation between lead for retractable pencil 17 and the intermediate plate 8 owing to write pressure, this frictional force passes to clamp ring 7 by steel ball 6 again, makes this frictional force amplified widely by clamp ring 7 female cone ramp effect, has stoped the retraction of lead for retractable pencil 17, be that lead for retractable pencil 17 is motionless, nib 1 up moves.
And pause or the nib 1 that finishes when leaving paper when writing, nib 1 and lead for retractable pencil 17 pressure disappear, and nib 1 is under the reset response of knockout spring 4, and lead for retractable pencil 17 resets with nib 1 by damping 3, compensated the abrasion of lead for retractable pencil 17 when writing, going round and beginning again has formed automatic propelling.
When lead for retractable pencil 17 uses up when need replenishing new lead for retractable pencil, as long as pressing the cap for brush of being located at penholder 15 ends drives core storage tube 16 simultaneously and send core pipe 13 to advance downwards, to send the guide pipe 11 of core mechanism to advance downwards, and continue to push up intermediate plate 8, intermediate plate 8 is continued to advance toward the big extreme direction of conical bore of clamp ring 7, intermediate plate 8 is opened automatically, at this moment lead for retractable pencil 17 can be straightway through core storage tube 16, the aperture of sending core pipe 13, guide pipe 11, intermediate plate 8 directly to fall damping 3.And discharge when pressing cap for brush pressure, core storage tube 16, send core pipe 13, guide pipe 11 to reset sending under core spring 14 and the effect that is connected spring 10, and that lead for retractable pencil 17 keep is motionless under the effect of gravity, through the cap for brush of pressing several times, lead for retractable pencil 17 can arrive 1 mouthful of place of nib, is in the state of can writing.
The utility model makes pencil can compensate lead for retractable pencil automatically in writing process by structural design, so when long-time continuous is write, do not need to go again to press out lead for retractable pencil with finger, many standby thin lead for retractable pencils can be placed in inside, make things convenient for the consumer to carry and use, this alternative Wood-bar pencil, save a large amount of forest tree resources, compliance with environmental protection requirements, suitable people particularly primary and secondary students use in daily life and study.
