Description

Have knockout of pushing and button and go out the full automatic pencil of cored structure
Technical field
The utility model relates to full-automatic side by pencil, relates in particular to and need not press, and can compensate the full automatic pencil that the knockout of pushing and button go out cored structure that has of the lead for retractable pencil that is worn in writing automatically.
Background technology
The general activity pencil that provides in the market, though thin lead for retractable pencil is non-sharpenning, many lead for retractable pencils of internal memory can be pressed knockout, want normal pressing when writing, and lead for retractable pencil is exposed, and just can write the too many easily broken core of knockout.Although have be improved to side by with the whipping knockout, just convenient, do not have basic solution.Propelling pencil bans the use of in primary school one, a lot of schools of second grade, because the pupil is very good moving, and propelling pencil is too movable, and pen is often dismounted badly, and influence study is so be main with Wood-bar pencil still.
Full-automatic propelling pencil, be called full-automatic side again by pencil, when it can be write without pressing, can compensate lead for retractable pencil automatically, the internal memory core of general activity pencil being arranged again and press the knockout function, be propelling pencil of new generation, but it does not jump out general activity pencil notion, many people also are used as the general activity pencil and use, and press to press head and expose lead for retractable pencil and write.Add processed complex, the precision height can not can be produced greatly always, and is also few on the market.
Full-automatic side is pressed pencil, also claim simple and easy full-automatic side by pencil, its outstanding automatic compensation function removes and presses knockout, internal memory core function, be different from the general activity pencil fully, similar Wood-bar pencil, it can only be write, and can not press, can not tear open, the lead for retractable pencil core that can not break in nib exempts from again to cut, and is easy to use.The simple and easy full-automatic side in Taiwan is pressed pencil product pin in the sixth of the twelve Earthly Branches about ten years, but simple and easy full-automatic side in the past has certain deficiency by pencil, the ZL90210687.2 patent documentation be the full-automatic side of plain type by pencil, it has only the sandwich and the automatic function of compensation knockout, once uses up with the lead for retractable pencil of a long 120mm.But it is very inconvenient that this pen adds core, and can only knockout, can not return.Insufficiency is so market sales volume is little always.
Summary of the invention

The design principle of the utility model embodiment is as described below:
Have knockout of pushing and button and go out the full automatic pencil of cored structure, its outstanding automatic compensation function, comprise the core pulling mechanism in the point cover 6 and sandwich mechanism forms and penholder in loose chuck mechanism with add lead for retractable pencil guiding mechanism mechanism.Core pulling mechanism and sandwich mechanism are two independently mechanisms in point cover 6, can play a role separately, are convenient to assemble and ensure the quality of products.Core pulling mechanism in the point cover 6 is overlapped 6, is drawn core spring 4, spring base 2, retaining core pipe 1, damping 3, back-up ring 5 to form by point.Lead for retractable pencil need not expose when writing, and it works the core effect of protecting, and lead for retractable pencil can not fracture.Lead for retractable pencil constantly weares and teares in writing, and retaining core pipe 1 is retreated, and core spring 4 is drawn in compression, when writing the gap when lifting, when drawing core spring 4 to reset, by the frictional force of damping 3 and lead for retractable pencil 19 lead for retractable pencil 19 is pulled out, and plays the effect that replenishes lead for retractable pencil 19.Sandwich mechanism is made up of retainer 7, steel ball 8, movement spring 9, intermediate plate 10, retainer seat 11.Have lead for retractable pencil 19 one-way movement functions, when lead for retractable pencil 19 retreated, intermediate plate 10 was embraced lead for retractable pencil 19, because steel ball 8 and retainer 7 ramp effect, retainer 7 is a metalwork, and the hardness height can guarantee lead for retractable pencil 19 is retreated.When drawing core forward, steel ball 8 can unclamp at once, makes intermediate plate 10 unclamp lead for retractable pencil 19, and lead for retractable pencil 19 can replenish lead for retractable pencil 19 forward.
By penholder 20, press bar 15, side button 14, returning spring 13 and push away circle 12 and form, when not using, press bar 15 under returning spring 13 effects, all the time stand away with intermediate plate 10, pressing side button 14, button inclined-plane 14a is relative with inclined trough surface 15c to slide, radial motion becomes axially-movable, make to press bar 15 and push away circle 12 to travel forward, push away the frictional force part usefulness in circle 12 head 12b and the collar seat hole, promotion sandwich mechanism fine motion together stretches out lead for retractable pencil 19 trace.Push away forward, retainer seat 11 locating piece 11a overlap among the 6 square hole 6a at point and withstand again, and retainer 7 no longer marches forward, and push away circle 12 and slide in retainer seat 11, press bar 15 heads and push up intermediate plate 10, and steel ball 8 is loosening, unclamps chuck, and lead for retractable pencil 19 just can retreat.Play trace and go out lead for retractable pencil 19 and the effect of deleading core.Decontrol side button 14, under returning spring 13 effects, press bar 15 rollbacks and break away from intermediate plate 10, movement spring 9 is strained chuck, and lead for retractable pencil is clamped and can not be retreated by intermediate plate.Recover former function.
The lead for retractable pencil guiding mechanism by rubber seat 18, press bar 15, push away circle and 12 forms, press the taper hole 15a that 90 degree are arranged on the bar 15, make things convenient for lead for retractable pencil 19 to add, press diameter on the bar 15 less than the endoporus 15b of two lead for retractable pencils, guarantee that lead for retractable pencil 19 heads into Shi Buhui partially and stuck.Pressing bar 15 heads has muscle 15e and pushes away circle 12 close-fittings, and pushing away circle 12 has in the retainer seat 11, makes the hole of pressing bar 15 aim at intermediate plate 10 holes, presses bar 15 external diameters with penholder 20 hole pines are joined, and guiding mechanism can insert intermediate plate 20 holes in the center of penholder 20 during adding lead for retractable pencil 19 smoothly.Lead for retractable pencil 19 is pressed onto in the damping 3 of protecting core with rubber seat 18 end faces, pressing retaining core pipe 1 just can be pulled out retaining core pipe 1 to lead for retractable pencil 19.
Full-automatic plumbous side is by the core pulling mechanism and the sandwich mechanism optimal design of pen, outstanding automatic compensation function, and quality is guaranteed, and has side and can go out lead for retractable pencil and deleading core by trace by mechanism and the guiding mechanism that adds lead for retractable pencil when pressing the side button, and is easy-to-use.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
