Abstract
The invention relates to an active pencil with a standardized lead core. The active pencil comprises a pencil point cap and a pencil holder cap positioned on a bar. Wherein, a pencil-holder in a round pipe shape has the inner wall of the front end arranged with inner screw thread and the inner wall of the rear end arranged with a retainer ring, the interior of the pencil-holder is positioned with a core-regulating axle-box with a prism-like through hole at the center, on the axle-box positioned at the rear is positioned with a circular cylinder lug boss which matches with the retainer ring on the inner wall of the pencil-holder, the core-regulating axle-box end at the rear of the circular cylinder lug boss connects with a core-regulating button via a connecting device, the external end face of the circular cylinder lug boss on the core-regulating axle-box matches with a round retainer shoulder of the pencil holder cap. The prism bar end of a core-regulating handspike arranged in the pencil holder is positioned with a concave end face possessing nut, the nut matches with the inner screw thread of the pencil holder, the prism bar is in a sliding matching with and positioned in the prism-like through hole in the core-regulating axle-box, the pencil point cap is internally arranged with a rubber locating ring which is provided with a through hole at the center to realize a static matching with a lead core. The utility model may can be applied to standardized lead cores of different diameters and endow the writing and painting with the same handling and effect as that of wooden-bar pencils.
Description
Technical field
The utility model belongs to the improvement of propelling pencil structure, particularly a kind of propelling pencil that uses the standardization lead for retractable pencil.
Background technology
Propelling pencil because it does not use rod, is saved timber resources, has also improved the utilization rate of lead for retractable pencil simultaneously, now is widely used.According to the propelling movement and the fixture of propelling pencil lead for retractable pencil, and before can be divided into that shaft of a writing brush fluting is fixed, push type and spiral three major types.Wherein: shaft of a writing brush fluting is fixed to be inconvenient to write because of it and to be eliminated gradually.The push type propelling pencil can only use thin lead for retractable pencil, and it is not good to write feel, and the lead for retractable pencil frangibility.Screw type propelling pencil can use the slightly lead for retractable pencil of some of diameter, has certain use value.Patent No. CN00206822.2, title: the free ever sharp pencil and the patent No.: CN02696326, title: a kind of propelling pencil belongs to screw type propelling pencil, their weak point is lead core cover will be contained in the lead for retractable pencil folder, and lead for retractable pencil folder packs in the steel helix tube again or in the threaded rod of hollow, because the internal diameter of helix tube or screwed pipe is fixed, employed lead for retractable pencil thickness degree is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of propelling pencil that uses the standardization lead for retractable pencil, not only can constantly release lead for retractable pencil according to the needs of writing, and go for the standardization lead for retractable pencil of different-diameter, can make the feel of writing, drawing the same with Wood-bar pencil with effect.
The purpose of this utility model is achieved in that a kind of propelling pencil that uses the standardization lead for retractable pencil, comprise pen cap that the penholder front end is installed and the pen clip cap of installing by screw thread in the penholder rear end, penholder is a hollow circular tube, on the inwall of penholder front side, internal thread is being set, on the inwall of penholder rear end back-up ring is being set, the center that is installed with in penholder has the accent core sleeve of prismatic through hole, the cylinder boss that is provided with on the boss face at its rear portion matches with back-up ring on the penholder inwall, the accent core sleeve termination at cylinder boss rear portion links together by jockey and core-adjustable button, transfer the outer face of core sleeve's cylinder boss to match with the annular shoulder block of pen clip cap, its prismatic boom end of accent core push rod of installing in penholder is being provided with the nut that end face has pit, nut matches with the internal thread of penholder, prismatic bar is slidingly installed in the prismatic through hole in transferring core sleeve, and the center that is installed with in the pen cap of penholder front end has the rubber centring ring with lead for retractable pencil stationary fit through hole.
When using the utility model, the counter-rotating core-adjustable button drives accent core sleeve and rotates, and makes and transfer the prismatic bar of the accent core push rod of installing in the prismatic through hole of core sleeve to drive the nut rotation, and nut moves backward to the position along the penholder internal thread.Unload the pen cap that the rubber centring ring is housed, one end of lead for retractable pencil is inserted in the through hole of rubber centring ring, the pen cap that lead for retractable pencil is housed is installed on the penholder, and the other end of lead for retractable pencil matches with the pit of transferring core push rod end nut end face, and lead for retractable pencil is positioned on the center line of penholder inside.The forward rotation core-adjustable button drives the prismatic bar of transferring the core push rod rotates the nut of end, and nut moves forward along the penholder internal thread, and the blind hole compressing lead for retractable pencil of nut end travels forward, and makes lead for retractable pencil expose needed length from pen cap and gets final product.
Because the through hole and the lead for retractable pencil stationary fit of the rubber centring ring of installing in the pen cap, the elasticity through hole of rubber centring ring be applicable to the standardized lead for retractable pencil of different-diameter, but also can be equipped with the rubber centring ring of corresponding specification according to the lead for retractable pencil of different-diameter.The propulsive mechanism of lead for retractable pencil matches with the penholder internal thread for the nut of transferring the core push rod, therefore, both can reach the purpose of fine setting lead for retractable pencil length, has solved the drawback that lead for retractable pencil becomes flexible and bounces back again.The utility model structural design advantages of simple, easy to use.Owing to can use the standardization lead for retractable pencil, can make the feel of writing, drawing the same with Wood-bar pencil with effect.
