CN203185895U - Carbon pen capable of being used in weightlessness - Google Patents

Abstract

The utility model discloses a carbon pen capable of being used in weightlessness, belongs to school supplies, and particularly relates to a carbon pen capable of being used in weightlessness and used in weightless and special working environments. The carbon pen capable of being used in the weightlessness comprises a pen rod, a pen cap and a pen point, and is characterized in that three guide clamping grooves are evenly formed in outer surface the upper section of the pen rod from top to bottom, a stirring block penetrating through he guide clamping grooves is arranged at the top end inside an outer shell, the stirring block is connected to the top end of a push rod in a sleeved mode, a resisting spring sheet is fixedly arranged at the 1/3 position of the top end of the push rod, a compression spring is arranged on the push rod between the resisting spring sheet and the stirring block, a rubber plug with the diameter equal to that of an ink bin is fixedly arranged at the bottom end of the push rod, and the rubber plug is connected in a pen refill in a sleeved mode. The carbon pen has the advantages that the ink in the ink bin is pushed and squeezed to the pen point through the elastic force of the spring, the carbon pen can be used for conveniently writing in the weightlessness and at the places where the carbon pen needs to be inversely placed to operate, the situation that work is delayed due to the fact that the ink cannot be out of the pen refill cannot occur, and the carbon pen is more practical than a common carbon pen in a special environment.

Description

Weightless carbon pen

Technical field

The utility model belongs to daily necessities, particularly a kind of weightless carbon pen that uses in weightless and particular job environment.

Background technology

Usually common carbon pen can only can be worked when normal the use smoothly, maybe needs but cisco unity malfunction of the inverted place of pen in weightlessness.

The utility model content

Can not maybe need pen is inverted the deficiency of the local work that uses in state of weightlessness in order to overcome the traditional carbon pen, the utility model provides a kind of weightless carbon pen, this weightlessness carbon pen not only can normally use under conventional environment, and can use in weightlessness or particular job environment.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of weightless carbon pen, comprise penholder, the cap for brush, nib, it is characterized in that: the epimere appearance of penholder is evenly distributed three guiding draw-in grooves from top to bottom, the portion top arranges a shifting block by the guiding draw-in groove in the enclosure, shifting block is socketed on the push rod top, one of three parts locate to fix a resistance reed apart from the push rod top, the resistance reed and set ahead between push rod on the compression spring is housed, the bottom of push rod fix one with the rubber stopper of ink storehouse equal diameters, rubber stopper is socketed in the pen core.

The beneficial effects of the utility model are, rely on the elastic force of spring that the printing ink in the ink storehouse is pushed to nib, write easily in state of weightlessness with in the place that carbon pen need be inverted operation, be unlikely to not write word and dally over one's work because pen core does not go out printing ink, demonstrate in particular surroundings the practicality than normal carbon pen.
