Abstract

The utility model provides a rotary propelling pencil, which is composed of a pencil cap (4), a pencil point (6), a rotary sleeve (11), a pencil holder (13) and a pencil tail (16), wherein, a device for sharpening a lead is attached in the pencil cap, and the lead can be changed after run out. When the rotary propelling pencil is used, only the pencil point needs to be turned lightly, the lead can limberly flex. The utility model has all advantages of woodiness pencils, and the use is convenient and practical, the worry for cutting pencils can also be exempted, the rotary propelling pencil can replace various woodiness pencils used at present, and fits for pupils, drawers, fine arts workers and woodworkers to use, and therefore, the rotary propelling pencil has a biggish market at home and abroad.

Description

Rotary propelling pencil

The utility model relates to a kind of stationery, especially a kind of rotary propelling pencil.

The propelling pencil that uses is a push type at present, its advantage is that the pen core elongation is quick, simple in structure, shortcoming is the pen core retraction pressure that will press...with one's finger in addition, and refill expansion can not be finely tuned, to the effort of the thick refill expansion more than the 2mm, therefore, can not replace all Wood pencils, to have fritter to collapse scarce for pen core when cutting, and the nib that is whittled into owes smooth.

The purpose of this utility model provides and a kind ofly can replace all Wood pencils, and pen core can stretch flexibly, and the flexible rotary propelling pencil that can finely tune.

The utility model is made up of the cap for brush, nib, rotary sleeve, penholder and a tail.With being threaded, rotate nib with hand between nib, rotary sleeve and penholder and the tail, pen core promptly elongates or shortens under the effect of accent core device in rotary sleeve, so that use.

The utility model is compared its advantage, characteristics and good effect with existing push type propelling pencil: mill during nib pen core frangibility and nib are smoothless; pen core flexible agile and fine-tuning; and the change-fountain pen core is easy; more prior is that the utility model can replace Wood pencil; can save the timber that is used to make Wood pencil in a large number, protect the forest reserves that the human ecology balance is played an important role.

Do the detail explanation below in conjunction with accompanying drawing.

Fig. 1 is the utility model pen cap structure schematic diagram.

Fig. 2 is the utility model handwriting structural representation.

The new punishment of this practicality is by the parts of the cap for brush (4): the parts in carborundum disc (1), leakproof pad (2), reed (3), penholder (5) and the handwriting: nib (6), core pipe (7), transfer core device (8), small blade (9), leakproof circle (10), rotary sleeve (11), lock screw (12), penholder (13), square pen core (14), square shaped core groove (15), a tail (16), spring (17) to be formed.

Totally two of carborundum discs (1), it is the rectangle thin slice, become the herringbone device, the top of intersecting is last and be in nib and insert when using up the cap for brush nib and reach among the place on the axis, the lower end is that mid point separates with the axis, separately width=pen core thick+1mm, sand sheet top is to lower end height 6mm, its purposes is the sharpening pen core.

Leakproof pad (2) is in carborundum disc (1) lower end, make garden shape, thick 4mm by tightr and full of elasticity foamed plastics, cut three radial incisions from the garden heart to three directions, wire long incision 3-4mm is mutually hexagonal angle, and the leakproof pad separately when pen core inserted, it is closed to extract the back out, in case pencil does not spill, a movable port is adorned on cap for brush top, so as to remove be contained in cap for brush top pencil not.

Nib is equipped with core pipe (7) on (6) axis, garden shape, and internal diameter=pen core is thick, and front end links to each other with a mouth, long 10mm.

Rotary sleeve (11) Inner Front End is equipped with transfers core device (8), small blade (9), leakproof circle (10), transferring core device (8) is a female tooth device of opening in fact, steel is made, its effect is to open tooth to pen core, control the advance and retreat of pen core simultaneously, the path of transferring the core device is than the little 0.8mm of pen core, (when pen core is 2mm) or 1.6mm (when pen core is 4mm), big footpath be path+1 to 1.5mm, length 10mm to 15mm.

Small blade (9), the high-quality steel is made, by relative in twos, blade is to the garden heart, the knife back is skew back to the right, and with four small blades compositions crossing vertical again two the mutually perpendicular straight line angles at 45 with the axis of axis, two relative knife-blade the upper halfs are parallel, distance is big with pen core etc., second is cut into " Eight characters " shape, and bottom than the big 1mm of pen core, leakproof circle (10) makes that pencil is not unlikely to be spilt, but concentrate on nib, so that remove.

Rotary sleeve (11) rear end and penholder (13) front end socket, socket length 20mm has minimum gap between them, rotary sleeve can rotate under the socket shape flexibly, annular sulculus is arranged on the penholder of socket,, made the unlikely disengaging penholder of rotary sleeve (11) (13) by lock screw (12) and sulculus locking.

Axial device square shaped core groove (15) on the interior axis of penholder (13), isometric with penholder, the long 0.5mm of the groove square length of side of square side ratio pen core, in adorn square pen core (14), pen core length of side 2-4mm, the pen core afterbody is made the blind mortise shape, and head is made the tenon shape, so that change-fountain pen core time head and the tail joggle and make the pen core that runs low can continue use to come off automatically when surplus 15mm grows.

Tail (16) built-in spring (17), spring heads on pen core and send forward, the then also and then rotation of rotary sleeve of rotation nib, thereby make small blade (9) cut the garden pen core, pen core imports under the power of the top of spring transfers core device (8), and pen core transfers the core device to leave screw thread at the fixing quilt down of square shaped core groove, to the anticlockwise nib pen core is elongated or shortened so to the right, stretch out pen chew outer pen core pry into the cap for brush just can be the pen core sharpening, pencil can use.

The utility model can be implemented with the cooperation of each factory, but also sole investment production because it is simple in structure, convenient, practicality and pen core are not easily broken, is well suited for pupil, drawing, the fine arts, carpenter's use, so bigger domestic and international market is arranged.
