Abstract
The utility model relates to a double-cylinder push-pull large-capacity pen used in study and work of people. The double-cylinder push-pull large-capacity pen holds more ink at a time than a conventional pen does and thus can be used continuously for a longer time before next filling of ink. The double-cylinder push-pull large-capacity pen is characterized in that a rubber ring B is embedded in an annular groove in the outer wall of the bottom of a plastic barrel and is matched with a cylinder B for sealing; a rubber ring A is embedded in an annular groove on the outer side of a piston ring and is matched with the inner wall of the plastic barrel for sealing; one end of a folding rubber tube is connected with an end face of the piston ring through adhesion and the other end of the folding rubber tube is connected with the internal bottom face of the plastic barrel through adhesion; a plastic plug is tightly connected with the top of the plastic barrel; an inner hole of the plastic plug is in clearance fit with a hollow piston rod which is disposed in the folding rubber tube after passing through the plastic plug and the piston ring; a tail cap is in threaded connection with a pen holder; a cylinder A is disposed below the plastic barrel which is longer than the cylinder A; and a fan-shaped channel is disposed at the bottom of the plastic barrel. The double-cylinder push-pull large-capacity pen is provided with two cylinders, with the hollow piston rod being disposed in the folding rubber tube, so that the capacity for ink is improved and continuous service time after filling of ink is prolonged. The double-cylinder push-pull large-capacity pen is simple in structure and easy to use.
Description
Technical field
The utility model relates to a kind of during for people's study and work, the plug-type large volume fountain pen of twin-tub that disposable writing time is long.
Background technology
At present, the pen that people use in study and work is classified by its blotting mode pen with pull-push type, rubber tube squash type pen, spiral ink suction pen, and it is maximum wherein to belong to again needle tube type pen occupancy volume in general marketplace that pen with pull-push type namely is commonly called as.But above-mentioned these pen major parts are that short with length, that radius is less single cylinder container is as storing the prepared Chinese ink chamber.Because the limited length of penholder, the radius of penholder can not be too large, so that the amount of the disposable storage prepared Chinese ink of pen is less, disposable writing time is short, uses very inconveniently, is further improved and perfect.
Summary of the invention
The purpose of this utility model is: in order to increase in the penholder amount that stores prepared Chinese ink, to increase disposable writing time, the spy provides a kind of twin-tub plug-type large volume fountain pen.
In order to achieve the above object, the utility model is by the following technical solutions: the plug-type large volume fountain pen of twin-tub, to be consisted of by penholder, cylinder, plastic barrel, folding sebific duct, piston ring, plastic plug, hollow piston rod, tail cap, rubber ring, sector channel, passage, its architectural feature is: rubber ring B is embedded in the annular groove of plastic barrel bottom outer wall, cooperate with cylinder B again, seal; Rubber ring A is embedded in the annular groove in the piston ring outside, cooperates with the plastic barrel inwall again, seals; Folding sebific duct one end and piston ring end face bonding, its other end and plastic barrel inner bottom surface bonding play isolation prepared Chinese ink; Combining closely in plastic plug and plastic barrel top, plays the limited piston circle stroke that moves upward, and plastic plug endoporus and hollow piston rod matched in clearance work to support, stablize hollow piston rod; Hollow piston rod passes plastic plug and piston ring and is placed in the folding sebific duct, and tail cap and penholder are with being threaded; Cylinder A is arranged on the below of plastic barrel, and plastic barrel length is convenient to settle double-cylinder structure greater than cylinder A length 2-4mm; The plastic barrel bottom is provided with sector channel, is used for the prepared Chinese ink turnover.Hollow piston rod is set to hollow, avoids the effects of air pressure in the push-and-pull process, is provided with passage at the top of hollow piston rod, so that the gas in the folding sebific duct is discharged by passage.
The beneficial effects of the utility model are: (1) adds that by adopting the ingenious cooperation of twin-tub hollow piston rod places folding sebific duct, has reached increase pen prepared Chinese ink volume, increases disposable service time; (2) this large volume fountain pen is simple in structure, easy to operate, easy to use.

Fig. 1 is the structural representation of the plug-type large volume fountain pen of the utility model twin-tub;
Fig. 2 is this pen plastic barrel 3 bottom upward views;
Fig. 3 is that this pen hollow piston rod 8 amplifies partial sectional view;
Among the figure: 1, penholder; 2, cylinder A; 3, plastic barrel; 4, cylinder B; 5, folding sebific duct; 6, piston ring; 7, plastic plug; 8, hollow piston rod; 9, tail cap; 10, rubber ring A; 11, rubber ring B; 12, sector channel; 13, passage.
The specific embodiment
The plug-type large volume fountain pen of twin-tub as shown in Figure 1 is characterized in that: rubber ring B11 is embedded in the annular groove of plastic barrel 3 bottom outer wall, cooperates with cylinder B4 again, seals.Rubber ring A10 is embedded in the annular groove in piston ring 6 outsides, cooperates with plastic barrel 3 inwalls again, seals.Folding sebific duct 5 one ends and piston ring 6 end faces bonding, the other end and plastic barrel 3 inner bottom surface bonding play isolation prepared Chinese ink.Plastic plug 7 is combined closely with plastic barrel 3 tops, plays limited piston circle 6 stroke that moves upward.Plastic plug 6 endoporus and hollow piston rod 8 matched in clearance work to support, stablize hollow piston rod 8.Hollow piston rod 8 passes plastic plug 7 and piston ring 6 is placed in the folding sebific duct 5.Tail cap 9 is threaded with penholder 1 usefulness.Plastic barrel 3 length are convenient to settle double-cylinder structure greater than cylinder A2 length 2-4mm.Plastic barrel 3 bottoms are provided with sector channel 12 and are used for the prepared Chinese ink access way.Hollow piston rod 8 is set to hollow, avoids the effects of air pressure in the push-and-pull process.When preparing blotting, screw off first tail cap 9, extract the hollow piston rod 8 that is placed in the folding sebific duct 5 out, allow hollow piston rod 8 afterbody external screw threads and piston ring 6 inner hole threads screw.Then push away hollow piston rod 8 downwards, discharge gas and residue prepared Chinese ink among cylinder A2 and the cylinder B4, the gas in this process in the folding sebific duct 5 is discharged by passage 13.Upwards draw hollow piston rod 8, prepared Chinese ink enters cylinder A2 again, then enters cylinder B4 by sector channel 12, finishes blotting, and the gas in this process in the folding sebific duct 5 replenishes by passage 13.Screw off at last hollow piston rod 8, be placed in the folding sebific duct 5, screw on tail cap 9.
