Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, a novel press-jump pen comprises a pen holder 1, a press nib mechanism 2, a sleeve 7 and a pen nib 9, wherein an ink bag mechanism 3 is arranged in the pen holder 1, a blocking ring 8 is arranged at one end, close to the pen nib portion 9, in the pen holder 1, a spring 4 is arranged between the ink bag mechanism 3 and the blocking ring 8, a pen refill 5 is arranged at one end, close to the blocking ring 8, of the ink bag mechanism 3, a fixing block 6 is arranged at one end, close to the blocking ring 8, of the pen refill 5, a protruding block 61 is arranged on the fixing block 6, four grooves 71 are arranged in the sleeve 7, four grooves are formed in the sleeve 7, the outer diameter of the sleeve 7 is smaller than the inner diameter of the pen nib portion 9, and the spring 4 can elastically stretch along with the movement of the ink bag mechanism 3. During the equipment, cup joint spring 4 on refill 5, then with ink sac mechanism 3, refill 5 and spring 4 together are packed into from the upper portion of pen-holder 1, at last will press and go out sharp mechanism 2 and peg graft in pen-holder 1 top and accomplish the equipment, the user only needs to press and go out sharp mechanism 2 when using, it drives ink sac mechanism 3 and moves down to press out sharp mechanism 2, then ink sac mechanism 3 drives refill 5 and moves down and goes out nib portion 9 and write, when the user need not write, detain sleeve 7 on fixed block 6, four recesses 71 in sleeve 7 cooperate with four lugs 61 on fixed block 6, fix sleeve 7 on refill 5, press the side of going out sharp mechanism 2 at last, later ink sac mechanism 3 and press out nib mechanism 2 and refill 5 all are driven by the elastic shrinkage of spring 4 and reset, sleeve 7 also resets along with refill 5, enter into nib portion 9. This kind of novel press jump pen, the assembly is simple and can be with sleeve 7 inside the shrink enters into pen-holder 1 in the lump, and protection refill 5 does not receive the pollution when depositing for refill 5 is in the protected state when the pen does not use always, increases the life of pen, and sleeve 7 is located 1 inside unobtrusions of pen-holder, realizes hidden protection, does not influence placing and pleasing to the eye of pen.

In some embodiments, the tip pressing mechanism 2 includes a pressing block 21, a pen clip 22 is disposed on the pressing block 21, a swing strip 23 is disposed on the pressing block 21 and located between the pressing block 21 and the pen clip 22, a square groove 24 is disposed on the swing strip 23, an opening is disposed at an end of the pen holder 1 close to the tip pressing mechanism 2, and saw teeth are disposed on the opening, so that a user can press the pressing block 21 to enable the pressing block 21 to drive the ink sac mechanism 3 and the pen refill 5 to move downward, and meanwhile the pressing block 21 drives the swing strip 23 to move downward, and then the square groove 24 on the swing strip 23 is hung by the saw teeth on the opening at the upper end of the pen holder 1, and can write after fixing is completed, and after writing is completed, the pen clip 22 is pressed, and the pen clip 22 pushes the swing strip 23 to move in a direction away from the pen clip 22, so that the square groove 24 on the swing strip 23 is separated from the saw teeth, and finally the pressing block 21 is driven by elastic contraction of the spring 4 to reset.

In some embodiments, a protrusion is disposed on a side of the pen clip 22 close to the swing strip 23, and a user presses the pen clip 22 to drive the protrusion to move the swing strip 23 away from the pen clip 22, and then pushes the pen clip 1 upward to push the entire tip pushing mechanism 2 away from the pen holder 1, so as to dump the components in the pen holder 1.

In some embodiments, the outer diameter of one end of the fixing block 6 is larger than that of the other end, the stop block 72 is arranged in the sleeve 7, the outer diameter of the stop block 72 is between the outer diameters of the two ends of the fixing block 6, when a user sleeves the sleeve 7 on the pen core 5, the stop block 72 in the sleeve 7 is just blocked by the end with the large outer diameter of the fixing block 6, and the pen core 5 is prevented from being damaged due to too large force when the user sleeves the sleeve 7 on the pen core 5.

In some embodiments, the maximum outer diameter of the fixing block 6 is smaller than the inner diameter of the retaining ring 8, so that the fixing block 6 can pass through the retaining ring 8 without being blocked, and the refill 5 is convenient for a user to replace.

In some embodiments, the outer diameter of the sleeve 7 is larger than the inner diameter of the stop ring 8 and smaller than the outer diameter of the stop ring 8, so that the sleeve 7 is prevented from penetrating through the stop ring 8 into the pen holder 1 along with the shrinkage of the pen core 5 after being sleeved on the pen core 5, and the sleeve 7 is contacted with the spring 4 and clamped by the spring 4.

In some embodiments, the ink bag mechanism 3 includes an ink bag 31 and a connection column 32, the ink bag 31 is a piston-type ink bag, which is convenient for a user to perform ink pumping and replenishing, and is convenient for writing continuously, it should be noted here that the piston-type ink bag is of a conventional existing structure, and therefore, the detailed structure and working principle of the present embodiment are not described again.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
