Abstract
The utility model belongs to the technical field of writing tools and relates to a mechanical pencil with a lead box capable of being rotated upwards. The mechanical pencil comprises a pencil rod, the lead box, a pencil cap and a lead storage tube. The pencil rod is fixedly connected with the lead box through a rotating shaft. The lead box is in butt joint with the lead storage tube after being rotated 180 degrees around the rotating shaft. The top of the lead box is provided with a small hole with the diameter equal to the diameter of a pencil lead. A sealing cover is arranged on the top of the lead box. In the using process of the mechanical pencil, when the pencil lead needs to be replaced, the lead box is rotated, and then the pencil lead can be replaced conveniently and quickly; an independent lead box does not need to be carried with a user, hands are prevented from touching the pencil lead, and therefore the mechanical pencil is safe and sanitary; the phenomenon that a student forgets to carry a lead box, and consequently learning is influenced is avoided, time for seeking the lead box and replacing the pencil lead is shortened, operation is simple, and use is convenient.
Description
Technical field
The utility model belongs to writing tool technology field, specifically, relates to a kind of propelling pencil with rotating up plumbous box.
Background technology
Pencil is divided into propelling pencil and Wood pencil; Wood pencil is simple in structure, easily manufactured; but because lead for retractable pencil is by timber; when use, need cutting, for student, use inconvenience, the wooden chip cutting also to pollute environment around; simultaneously; the manufacture of Wood pencil has expended a large amount of timber resources, is unfavorable for the protection of environment, does not meet the requirement of environmental protection.Now propelling pencil be student especially pupil learn the first-selected instrument of use, the trouble that it has removed cutting from, has saved the time, easy to use.But the core work of changing of propelling pencil still needs manually to carry out, in order to ensure the use of propelling pencil, we will carry lead box, in the time that a pencil-lead is finished, just need to from lead box, takes out a new lead for retractable pencil and change.Because lead for retractable pencil is highly brittle, along with ceaselessly jolting, lead for retractable pencil just likely fractures before not using; When pupil writing is more, repeatedly repeat, finger contact lead for retractable pencil often, not only unhygienic but also easily lead for retractable pencil is fractureed, and sometimes forgotten band lead box, and propelling pencil does not just change core, has affected study.Chinese patent 201220273677.9 discloses a kind of propelling pencil with plumbous box, and it comprises penholder, and plumbous box is installed in the upper end of the side of said penholder, and buckle closure is installed in the upper end of plumbous box, and buckle closure and plumbous box clamp, and change lead for retractable pencil still needs the tactile lead for retractable pencil that catches at every turn.
Utility model content
The purpose of this utility model is to overcome the shortcoming that prior art exists, and seeks to design a kind ofly to add the propelling pencil of lead for retractable pencil by the plumbous box automatic powder adding that upwards overturns, and does not need to carry lead box, does not also need hand contact lead for retractable pencil when use.
To achieve these goals, the technical solution of the utility model is: a kind of propelling pencil with plumbous box, comprise penholder, lead box, the cap for brush, core storage tube, described penholder is fixedly connected with lead box by rotating shaft, described lead box docks with core storage tube after Rotate 180 degree around the shaft, described lead box top is provided with the aperture conforming to lead core diameter, and described lead box top is provided with seal cover.
Preferably, described core storage tube top is funnel-form, is convenient to and the docking of plumbous box.
Preferably, there is rubber sleave described lead box outside, prevents that propelling pencil is because causing lead for retractable pencil fracture with other stationery collisions.
Preferably, described seal cover is rubber cap or push-and-pull lid.
In propelling pencil use procedure, after the lead for retractable pencil in core storage tube is finished, first unplug the cap for brush of propelling pencil, unplug again the seal cover at lead box top, by lead box Rotate 180 degree around the shaft, lead box is docked with core storage tube, allow the aperture at lead box top aim at the center of core storage tube, rock slightly, just can closely enter in core storage tube along aperture at next root lead for retractable pencil of Action of Gravity Field, then lead box is resetted, build seal cover and the cap for brush, change lead for retractable pencil and complete, press the cap for brush, by lead for retractable pencil output block, lead for retractable pencil is transported to nib, can write.
The beneficial effects of the utility model are: while carrying out lead for retractable pencil replacing in propelling pencil use procedure, by rotation lead box, realize conveniently lead for retractable pencil and change, both need not carry independent lead box, avoided again hand contact lead for retractable pencil, safety and sanitation; Avoid student to leave behind lead box and affected the generation of learning phenomenon, having reduced the time of finding lead box replacing lead for retractable pencil, simple to operate, easy to use.
