The specific embodiment
A possible embodiments of the present utility model as depicted in figs. 1 and 2, it provides a kind of multi-purpose machinery formula automatic propelling pencil, includes penholder 16 and pen core two parts, and pen core is made up of parts such as nib 2 and sleeve pipes 9.
Nib is provided with by protecting the knockout mechanism that core retainer plate 1, knockout spring base 3 and knockout spring 17 and damping 5 are formed in 2, protects core retainer plate 1 rear end and is provided with and protects core retainer plate seat 14.
What be provided with and push away core retainer plate 6, place the lock core mechanism (7,8,18,10), the top cover 11 that push away in the core retainer plate 6 in the sleeve pipe 9 successively, place the core storage tube 15 in the top cover 11 and place core storage tube 15 ends lifts the cap (not shown).
Described lock core mechanism includes clamp ring 8, steel ball 7, intermediate plate 10 and support spring 18, it is cone that clamp ring 8 outsides are the cylinder internal diameter, place the intermediate plate 10 of two semicylinders in this clamp ring 8, there is a ball pit at corresponding clamp ring 8 places and places steel ball 7 on the exterior arc surface of intermediate plate 10, front end sleeve one support spring 18 at two intermediate plates 10, the other end of support spring 18 contacts with the closing in that pushes away core retainer plate 6, and clamp ring 8 is set in and pushes away core retainer plate 6 Inner Front Ends.
The core pipe 111 excessively that narrows is arranged in the top cover 11, cross core pipe 111 two ends and push up cover 11 for the funnel type transition is connected, an end of top cover 11 is inserted in and pushes away end in the core retainer plate 6, and the other end of top cover 11 is inserted in 15 core storage tubes, be with top sleeve spring 19 outside the top cover 11, the other end of this top sleeve spring 19 contacts with sleeve pipe 9.
The end of sleeve pipe 9 has a moving casing 12 also, moving casing 12 is connected with a top cover clamping sleeve 13 by screw, this top cover clamping sleeve 13 has a top cover locking groove 131, in the cover clamping sleeve 13 of top, be right after top cover 11 and put a lock sleeve 14, this lock sleeve 14 is provided with a lock pin 141, and this lock pin 141 inserts in the top cover locking groove 131, places core storage tube 15 prolongations in the top cover 11 to pass top cover locking cover 14.
Operation principle:
Make the automatic propelling pencil when writing, assembling is state shown in Fig. 1～8, the end of the lead for retractable pencil 20 in the automatic propelling pencil contacts with paper, with moving of beginning to write, lead for retractable pencil 20 constantly is worn away when shortening, protect that core retainer plate 1 also contacts paper simultaneously and the upward pressure when being write and up moving, displacement equals lead for retractable pencil 20 abrasion length, and knockout this moment spring 17 also compresses this distance.Can make frictional force of generation between lead for retractable pencil 20 and the intermediate plate 10 owing to write pressure, this frictional force passes to clamp ring 8 by steel ball 7 again, makes this frictional force amplified widely by clamp ring 8 female cone ramp effect, has stoped the retraction of lead for retractable pencil 20, be that lead for retractable pencil 20 is motionless, protect core retainer plate 1 and up move.
And pause or finish when protecting core retainer plate 1 and leaving paper when writing, protect core retainer plate 1 and lead for retractable pencil 20 pressure and disappear, protect core retainer plate 1 under the reset response of knockout spring 17, lead for retractable pencil 20 resets with protecting core retainer plate 1 by damping 5, compensated the abrasion of lead for retractable pencil 20 when writing, going round and beginning again has formed automatic propelling.
When lead for retractable pencil 20 uses up when need replenishing new lead for retractable pencil, be located at the cap for brush that is exposed to the penholder end and make and drive core storage tube 15 simultaneously and top cover 11 advances downwards as long as press, cover 11 ends, top at first will push away core retainer plate 6 and advance downwards, after continue to push up intermediate plate 10, intermediate plate 10 is continued to advance toward the big extreme direction of conical bore of clamp ring 8, intermediate plate 10 is opened automatically, and at this moment lead for retractable pencil 20 can straightway aperture of directly falling damping 5 through core pipe 111, the intermediate plate 10 excessively of core storage tube 15, top cover 11.And discharge when pressing cap for brush pressure, overlap 11, reset under the effect of top sleeve spring 19 in core storage tube 15, top, intermediate plate 10 resets under the effect of support spring 18, and that lead for retractable pencil 20 keeps under the effect of gravity is motionless, through the cap for brush of pressing several times, lead for retractable pencil 20 can arrive and protect core retainer plate 1 exit, is in the state of can writing.
When making non-pencil purposes
Firmly push lock sleeve 14, make inside propelling top cover 11 (related core storage tube 15 simultaneously), pushing away core retainer plate 6 advances downwards, and continue to push up intermediate plate 10, intermediate plate 10 is continued to advance toward the big extreme direction of conical bore of clamp ring 8, intermediate plate 10 is opened automatically (as Fig. 1～6 and Fig. 9, state shown in Figure 10), at this moment rotational lock cover 14 fore shafts that make lock pin 141 snap in top cover locking groove 131 lock state, at this moment lead for retractable pencil 20 can be unblockedly at core storage tube 15, the core pipe 111 excessively of top cover 11, intermediate plate 10, move in the damping 5, when writing, lead for retractable pencil 20 moves freely along with protecting core retainer plate 1 by damping 5, lead for retractable pencil 20 does not protect outside the core retainer plate 1 because of not exposing without any resistance, this moment, lead for retractable pencil was not worn, and did not have the pencil function, and this moment, the utility model used as other lettering pen (writing pen as electron plate).
Be compared with the prior art, structure of the present utility model is more reasonable, and when doing the propelling pencil use, lead for retractable pencil exists Energy auto-compensation in the writing process does not need when long-time continuous is write to go to press out lead for retractable pencil with finger again, and pen is inner Can place branched thin lead for retractable pencil for subsequent use, make things convenient for the consumer to carry and use, in addition can be with this reality by locking device Be in non-pencil functional status with novel, at this moment the utility model is again that an electron plate is write pen or Fescue pen. Realized one multiplex.
