[0020] See also Figure 1-6 A sealable press-type fountain pen comprises a nib 1, a pen neck 2 and a lower rod 3, the nib 1 is mounted at the bottom end of the pen neck 2, the lower rod 3 is mounted at the top end of the pen neck 2, a positioning ring 4 is provided at the top end of the pen neck 2, a pen clip 5 is provided on the positioning ring 4, a push-pull 6 is slidably provided at the top end inside the lower rod 3, a pen core 7 is slidably provided inside the pen neck 2, a silicone sleeve 8 is provided at the bottom end of the pen neck 2, a sealing cover 9 is hingedly provided at the bottom end of the silicone sleeve 8, a tension line 10 is connected between the sealing cover 9 and the pen core 7, a fixing hole 11 is opened on the pen core 7 corresponding to the tension line 10, a fixing groove 12 is opened on the sealing cover 9 corresponding to the tension line 10, and a spring 13 is provided between the pen core 7 and the silicone sleeve 8.

[0021] In this embodiment, the push pull 6 pushes the internal pen core 7 downward, compressing the spring 13, and the pen core 7 passes through the pen head 1 and is ejected. When resetting, the spring 13 rebounds, and the tension line 10 pulls the sealing cover 9 to hinge and close.

[0022] See also Figure 2 , Figure 4 and Figure 5 As an implementation method of the pen tip 1 and the silicone sleeve 8: a card slot 14 is opened at the bottom end of the inner part of the pen tip 2 corresponding to the silicone sleeve 8, a first installation groove 15 is opened at the top of the outer end surface of the pen tip 1, and a second installation groove 16 is opened on the inner wall of the card slot 14 corresponding to the first installation groove 15, and the first installation groove 15 and the second installation groove 16 are threadedly matched.

[0023] Specifically, the silicone sleeve 8 is installed corresponding to the card slot 14, and between the pen head 1 and the pen neck 2, the first installation slot 15 and the second installation slot 16 are threadedly matched and rotatably installed.

[0024] See also Figure 3-5 As an implementation method of the lower rod 3: a third mounting groove 17 is opened at the top of the outer end of the pen tip 2, and a fourth mounting groove 18 is opened at the inner bottom end of the lower rod 3 corresponding to the third mounting groove 17, and the third mounting groove 17 and the fourth mounting groove 18 are threadedly matched.

[0025] Specifically, when the pen head 2 and the lower rod 3 are correspondingly installed, the third installation groove 17 and the fourth installation groove 18 are threadedly matched and rotated to install.

[0026] In summary, the overall equipment is in use:

[0027] When in the assembled state, the silicone sleeve 8 is installed corresponding to the card slot 14 of the pen item 2, one side of the tension wire 10 is installed at the fixing slot 12 position of the sealing cover 9, and the other side is installed corresponding to the fixing hole 11 position of the pen core 7 inside the pen item 2, and then the pen tip 1 and the lower rod 3 are installed as a whole, the first installation slot 15 of the pen tip 1 and the second installation slot 16 of the pen item 2 are installed in coordination, and the third installation slot 17 of the pen item 2 and the fourth installation slot 18 of the lower rod 3 are installed in coordination.

[0028] When in the pressed use state, the push pull 6 is pressed to push the pen core 7 downward, squeezing the spring 13, and the clamping mechanism inside the lower rod 3 clamps the push pull 6. When the pen core 7 is pushed downward, the hinged sealing cover 9 is pushed open and extends outward through the pen head 1.

[0029] When in the reset state, the push pull 6 is pressed again, and the internal clamping mechanism no longer clamps the push pull 6. The spring 13 rebounds, driving the push pull 6 and the pen core 7 to bounce up and down. The pen core 7 is retracted upward and the tension line 10 is pulled to close the hinged sealing cover 9. The sealing cover 9 and the silicone sleeve 8 cooperate to seal and protect the tip of the pen core 7.

[0030] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
