Specific embodiment:

The present invention will be further described with attached drawing combined with specific embodiments below.

As shown in Fig. 1 to 9, be a kind of alternate form writing pen, comprising: pen tube 1, the pen core 2 for being set to 1 front end of pen tube, It is set to 1 rear end of pen tube and is used to provide the print cartridge 4 of ink to pen core 2, is installed on 1 rear end of pen tube and for print cartridge 4 is fixed Rear cover 5 and the black adjustment structure 6 of leading that is set between pen core 2 and print cartridge 4, the print cartridge 4 removably pacify Loaded on 1 rear end of pen tube, which includes print cartridge bottle 41, the ink box cover 42 for being installed on 41 opening of print cartridge bottle and is set to ink Valve body 43 in box cover 42,42 outer wall of ink box cover at least form there are two seal bulge loop 421, the sealing bulge loop 421 with Print cartridge bottle 41 is fixed, and is in close contact；Described black 6 one end of adjustment structure of leading is connected to by opening valve body 43 with print cartridge bottle 41； The valve body 43 includes valve seat 431 and is installed in valve seat 431 in channel 432 and heads into ink being led black adjustment structure 6 For stirring the sphere 433 of ink in print cartridge bottle 41 after box bottle 41.431 thickness of valve seat is gradually thinning from thickness, so that valve Seat 431 has certain elasticity tension, and after sphere 433 is installed in channel 432, valve seat 431 is opened by the elasticity of itself Sphere 433 is fastened in channel 432 by power, and valve body 43 is made to be in sealing state, to guarantee the airtightness of ink box cover 42.

The print cartridge 4 can be back to manufacturer by way of waste recovery after replacement, and producer is by will be black Ink box cover 42 in box 4 is opened, and the sphere 433 fallen into print cartridge bottle 41 is taken out, then by sphere 433 on the inside of ink box cover 42 It reinstalls in the channel 432 of valve seat 431, ink is then refilled in print cartridge bottle 41, and ink box cover 42 is pacified again It is attached on print cartridge bottle 41, to realize the recycling of print cartridge 4.

The ink box cover 42 is fixed by the sealing bulge loop 421 for taking shape in one end with the print cartridge bottle 41, described 42 other end of ink box cover and the print cartridge bottle 41 between formed third cavity 44.

The black adjustment structure 6 of leading includes to lead ink in the insertion channel 432 of one end and by what the sphere 433 opened The continuous pipe 62 of black device 61 and pen core 2 is led in device 61 and connection, and described 2 one end of pen core is inserted into the continuous pipe 62.Described leads Black device 61 includes tube body 611, takes shape in the first convex pipe 612 of 611 side of tube body and take shape in the second of 611 other side of tube body Convex pipe 613, the convex pipe 613 of described second be inserted into the ink box cover 42 by the sphere 433 head into print cartridge bottle 41 with Print cartridge bottle 41 is connected to；Convex 612 end of pipe of described first is at zigzag and is inserted into continuous pipe 62, the convex pipe 613 of described second Tube wall is provided with port 614.When installing print cartridge 4, the sphere that will be mounted in ink box cover 42 in valve body 43 by the second convex pipe 613 433 head into print cartridge bottle 41, so that the channel 432 in ink box cover 42 in valve body 43 be opened, make ink along the second convex pipe 613 Port and the outflow of two side ports 614, reach in continuous pipe 62, when pen tube 1 is upright, the second convex pipe 613 for leading black device 61 can be prevented Sphere 433 seals the channel 432 of valve body 43, and in use, the sphere 433 fallen into print cartridge bottle 41 can stir ink Uniformly, ink color remains unchanged when making to write.

The convex pipe 615 of third, the convex pipe 615 of the third and pipe are provided between the tube body 611 and the second convex pipe 613 It is formed with the first cavity 616 between body 611, is formed with the second cavity between the convex pipe 615 of the third and the second convex pipe 613 617；The convex pipe 615 of the third is inserted into the third cavity 44, first described in 41 one end of print cartridge bottle insertion In cavity 616, in 42 one end of ink box cover insertion, second cavity 617.It is convex by third after the installation of print cartridge 4 Pipe 615 is inserted into third cavity 44 and 41 one end of print cartridge bottle is inserted into the first cavity 616, makes convex 615 side of pipe of third and print cartridge Bottle 41 is in close contact, and the other side and ink box cover 42 are in close contact, so that the ink in print cartridge bottle 41 is not after guaranteeing that print cartridge 4 is installed It can directly be contacted with air, ink can only be flowed into continuous pipe 62 by leading black device 61 and steadily be exchanged with air, therefore, ink It cannot flow into the gap of print cartridge 4 and pen tube 1 and generate ink leak.

The rear cover 5 is installed on 1 rear end of pen tube by the way of being threadedly coupled.After print cartridge 4 installs, You Bihou The rotation of lid 5 is tightened, and print cartridge 4 is fixed in pen tube 1.The black device 61 of leading is fixed with pen tube 1.Before the pen tube 1 End cap is equipped with a front cover 3, and the front cover 3 covers the pen core 2, can provide tight function when not in use, prevents Only pen core ink is killed.

The black device 61 of leading is engaged by the inclined-plane 618 taken shape on outer wall and the first bulge loop 619 with 1 inner wall of pen tube admittedly It is fixed, first bulge loop 619 at least there are two.The second bulge loop 422 is formed in the middle part of the ink box cover 42, second bulge loop 422 compress with the ladder 411 taken shape on 41 inner wall of print cartridge bottle.

3 outer surface of front cover is in hexagon, and 5 outer surface of rear cover is in hexagon.By 3 appearance of front cover Face is arranged using hexagon, plays the role of anti-roll, conveniently chooses, while also hexagon being used to be arranged 5 outer surface of a rear cover, increases It puts english and turns the point of application, rolling when preventing from reversing facilitates extraction.The pen tube 1 is tapered, is gradually increased from front end to rear end. By pen tube 1 be arranged to rear end be slightly larger than front end structure type, with facilitate from rear end installation lead black adjustment structure 6 and print cartridge 4 and Rear cover 5.

In conclusion the utility model first unscrews a rear cover 5 when installing and replacing print cartridge 4, and take out, pen tube 1 is erected Getting up makes a front cover 3 upward, is then slowly withdrawn old print cartridge 4, then new print cartridge 4 is inserted from 1 rear end of pen tube vertically upward Enter, the sphere 433 in ink box cover 42 is headed into print cartridge bottle 41 by the second convex pipe 613 led in black device 61, beats channel 432 Open, then screw a rear cover 5, when pen core 2 downward when, ink is along leading the port of the second convex pipe 613 and two side ports 614 in black device 61 Outflow；When in use, ink edge out of print cartridge bottle 41 leads black device 61 and flows into continuous pipe 62, and You Mianguan 62 controls ink and does with air Replace convection current, guarantee is led at black 61 the first convex pipe 612 of front end of device ink outflow and is stablized, make pen core 2 when writing it is out of ink uniformly and Ink overflow is stablized, and writing smoothly effect is reached.

It certainly, is not to limit the utility model and implement the foregoing is merely specific embodiment of the utility model Range, all equivalent change or modifications done according to structure, feature and principle described in present utility model application the scope of the patents, should all wrap It includes in present utility model application the scope of the patents.
