Abstract

The utility model relates to an ink supplying device from the external side of a pen shell by means of pressing. The device uses a hollow cavity of a circular tube of a pen body as an ink storing circular tube (2), the inside of which is provided with a piston (3) which can move up and down and is intimately matched with the tube wall of the ink storing circular tube, the piston (3) is connected with a button (5) by a connecting rod (4), the majority of the button is exposed out of the pen body, and the button is the operation section of the ink supplying device. When the utility model supplies ink, a finger pushes the button; when a hand looses, the button drives the piston to rise by the direct action of a spring (6), and then the ink is supplied. Because the direct operation section is the button, ink can be supplied rapidly and high efficiently, and the pen body does not need screwing.

Description

The external pressing of pen is drawn ink apparatus

The utility model relates to a kind of device that draws ink from the pen hull outside with the method for pushing.

In the present existing technology, more pen adopts the interior hose of body to draw and holds ink, and extruding rubber makes and occurs negative pressure in the pipe, unclamps hose and then utilizes atmospheric pressure to draw full ink.This method shortcoming is a body of must turning on and screw on, and a body often twists not open because of overtorquing, and the service routine complexity can't " one-handed performance ".

The purpose of this utility model is that a kind of improved ink apparatus that draws will be provided, and utilizes it to realize that pen draws " one-handed performance " of ink, to simplify procedures, raises the efficiency.

The purpose of this utility model is achieved in that utilizes a body cavity to make the black pipe of cylindrical storage to hold ink, one and the close-fitting valve piston of tube wall are arranged in the pipe, this piston links to each other with cylindrical button outside stretching out a body by connecting rod, spring action is arranged on button, button, piston all are positioned at peak at ordinary times.Body part and pen head part are for being threaded.Press the button and unclamp, ink is sinked the black pipe of storage thereby piston is risen by the power effect of connecting rod transmission by spring.

The utility model only need change that pen is original to draw black part, utilizes a pen body to do the black pipe of storage, and piston is connected with connecting rod, button, draws China ink automatically with the spring realization, so relatively simple for structure.Simultaneously since this device operation part---button is in outside the body, so compare operation with original device very easy.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 adopts pen appearance figure of the present utility model.Ratio is (1: 1)

Fig. 2 is the profile that draws device for ink according to the pressing that the utility model proposes.Ratio is (1: 1)

Fig. 3 draws device for ink (a body ink storage portion branch) and pen head part connection layout according to the pressing that the utility model proposes.This moment, button and piston all were pressed into minimum point.Ratio is (1: 1)

Fig. 4 is that button cooperates figure with a body inwall.Ratio is (2: 1)

Below in conjunction with Fig. 2,3,4 details and the working conditions that describe in detail according to the concrete device that the utility model proposes.

This device comprises a body main body (1), and storage black pipe (2) is arranged in the main body, and a piston (3) is arranged in the pipe, and piston (3) closely cooperates with the black pipe of storage (2).Piston (3) links to each other with button (5) by connecting rod (4), and button (5) is ejected outside the body main body (1) by spring (6) effect, is in position topmost thereby drive piston.Piston promptly is in position topmost among Fig. 2.

As shown in Figure 4, cylinder button (5) has 1/4 to be positioned at a body (1), with (1) matched in clearance.The button bottom sides has a square protrusion (a), and button can be moved up and down along the straight runner (b) on the body inwall, and projection this moment (a) is in straight runner terminal point and horizontal semicircle chute (c) starting point place.The button that turns clockwise, projection breaks away from vertical straight trough, and button is then locked, and can not move up and down, and projection is positioned at horizontal concrete chute (c) at this moment.

Spring (6) upper end directly acts on button, and the lower end is positioned the collar stop (7) on the body inwall, connecting rod (4) and block mesopore matched in clearance.

Storing black pipe (2) bottom center, to have circular hole (8) and pen head part to advance ink port (9) relative, a pen head part and a body part by screw thread in conjunction with the time, circular hole (8) communicates with advancing ink port (9), and is guaranteed to seal by the rubber washer (10) that is positioned between the two.As shown in Figure 3.

Piston (3) is when being displaced downwardly to minimum point, and stretches the thin plastic pipe (11) that the people stores black pipe and still has a space.Tubule (11) belongs to pen head part, guarantees that ink is in use smooth and easy to flow down.

During practical operation, rotate counterclockwise button (5), this moment, projection changed vertical chute (b) over to from horizontal concrete chute (c), pressed the button, and piston (3) is displaced downwardly to minimum point, and release button then moves on the piston, and ink enters the black pipe of storage under the atmospheric pressure effect.Clockwise rotate button, then button is lockable.

Draw black mode and compare with former, this process is simple, and efficient improves greatly.

Claims

1. the external pressing of pen is drawn ink apparatus, it is characterized in that this device utilizes a body as storage black pipe (2), one piston moving up and down (3) is arranged in it, and piston is connected by connecting rod (4) button (5) outer with exposing a body, and button is subjected to spring (6) effect to drive piston by connecting rod.

2. device according to claim 1 is characterized in that a body as the ink storage portion branch, and a body cavity is made the black cylinder of storage.
