Abstract

The utility model relates to a rubber pencil, and relates to the field of a writing tool in stationery commodities. The length and the diameter of the rubber pencil are almost the same as those of an existing ball-point pen. The rubber pencil is replaceable in pencil cores and can use the pencil cores of different diameters, lengths, shapes and colors. The rubber pencil is mainly composed of a screw cap pencil barrel, a screw push barrel, a rubber inner strip and a spiral eraser. When the rubber pencil is used, the pencil core is inserted into the rubber inner strip, and the push barrel is screwed up. When the pencil core becomes short, the push barrel is loosely screwed, and the pencil core is pulled out so that the rubber pencil can be reused. When the rubber pencil is not used, the push barrel is screwed back, and the left pencil core is pushed to the pencil barrel and hidden. When the pencil core is changed for a new one, the push barrel is screwed out, and the new pencil core is inserted in the pencil barrel. The rubber pencil does not waste wood, the pencil cores and the eraser can be used up, and therefore the rubber pencil is energy-saving, environment-friendly, multipurpose and durable. Besides, the pencil core can be hidden, is not prone to breakage and is durable. In addition, the rubber pencil is simple in structure, convenient to use and low in price, and is an ideal new generation of pencil at present.

Description

The rubber pencil

Technical field

The utility model rubber pencil relates to the writing implement field in the cultural goods.

Background technology

Pencil kind commonly used at present is a lot: the Wood-bar pencil of dominating market is arranged; The paper roll pencil of energy-conserving and environment-protective exempts to cut the propelling pencil of exempting to dig, the drawing pencil that thickness is different; Motley colored pencil and Texturized refined lead pencil, not only flat but also thick carpenter's pencil etc.Yet they all exist different separately shortcoming and defect: like, the waste timber that has, planing trouble, the complex structure that has, use inconvenience, rapid wear perishable, easily broken frangible, have with core not to the utmost, single with core, the cost that has occupies height, expensive.Therefore, not having desirable pencil at present occurs.

Summary of the invention

The utility model rubber pencil does not exist above-mentioned any shortcoming or deficiency.The technical problem that this rubber pencil embodies is: 1, with bar in the strong rubber system of elasticity, the parcel lead for retractable pencil tight tough firmly, be difficult for cataclasm; Bar degree of tightness nature, control core are conveniently in pushing; Lead for retractable pencil hole shrinkage is strong, can insert various lead for retractable pencils.

Pine, degree of having are effectively moved back in 2 usefulness spiral ejector sleeve push-tights; Ejector sleeve head hexagon, anti-roll profit are revolved; Inhale mutually with magnetic sheet, pad and to make pipe move back core to hide; The spiral rubber is arranged, can screw and use up.

Solving the technical scheme that above technical problem takes is: this rubber pencil mainly is made up of bar and spiral rubber in the nut shaft of a writing brush, spiral ejector sleeve, the rubber.At first with a nut shaft of a writing brush of metal system (1), line in the nut is arranged in suitable for reading, the shaft of a writing brush long 20 centimeters similar with Wood-bar pencil, 0.9 centimeter of rugosity diameter is similar with ball pen, following sharp-crested size is similar with lead bullion core rugosity; Make a joint spiral ejector sleeve (2) again, long 4 centimeters, rugosity and shaft of a writing brush nut are supporting, and ejector sleeve head hexagon can anti-roll profit revolve, one piece of magnetic sheet of end embedding (5) in the ejector sleeve; Again with bar (3) in the rubber of a form of a stroke or a combination of strokes of elastic caoutchouc system, 16.5 centimeters of length, rugosity is thinner slightly than the shaft of a writing brush, and interior bar center has a very thin lead for retractable pencil hole (8) to make lock pin usefulness, and fixing one piece of pad (6) can smoke with magnetic sheet mutually on the interior tube head; At last, system one joint is prepared some lead for retractable pencils (7) simultaneously than in long spiral rubber (4) the precession ejector sleeve of ejector sleeve, and whole rubber pencil parts are accomplished.

During use, need only the lead for retractable pencil hole (8) of lead for retractable pencil (7) being inserted interior bar, interior bar (3) is put in the shaft of a writing brush (1), screw with ejector sleeve (2) and just can use; Lead for retractable pencil is with after short, as long as unscrew ejector sleeve (2), pull out, screws and uses; With finishing, can revolve and move back ejector sleeve (2), lead for retractable pencil (7) nib setback shaft of a writing brush (1) under magnetic sheet, pad are inhaled mutually is built-in good; Add core, change core, can screw out ejector sleeve (2), bar (3) directly adds, changes various lead for retractable pencils in taking out.

Use the beneficial effect of this rubber pencil to be: do not take timber, need not planing, lead for retractable pencil, rubber made and used up, energy-conserving and environment-protective; More than one with, long usefulness, a nib can hide, pen core is continuous, durable in use; Simple in structure, easy to use, with low cost, low price are present desirable pencils of new generation.
