Description

Technical Field

[0001] The utility model relates to the field of writing utensils, and particularly relates to a decompression pen. Background Art

[0002] The existing pressing pens mainly drive the pen refill through a telescopic locking mechanism therein in a pressing manner. The conventional telescopic locking mechanism generally includes a pressing rod, a locking member and a guide rail. The pressing rod, the locking member and the guide rail slide relative to each other under the guidance of an inclined plane, so as to drive the locking member to rotate to switch between two card slots with different depths on the locking member, and further change the locking position of the locking member in the pen barrel to realize the extension and retraction of the pen refill.

[0003] The appearance form of the conventional pressing pen is fixed. Generally, corresponding patterns are printed on the surface of the pen barrel to improve the visual appearance effect of the pen. However, the overall visual appearance effect of the pen is fixed, and it is easy to cause visual fatigue after long-term use, thus reducing the attractiveness of the pen. At the same time, the existing conventional pressing pen can only be used for writing simply, with relatively single functions, and cannot meet the diverse needs of users for writing pens.

[0027] During the process of extending and retracting the pen core 31 in the pen body 1, the decorative bead 2 slides relative to the pen body 1 along the axial direction of the pen body 1, so that the decorative bead 2 displayed on the through hole 5 changes, thereby changing the visual effect of the pen when the pen core 31 is in the extended state and the retracted state. Moreover, since the decorative bead 2 can be exposed through the through hole 5, the user can move the decorative bead 2 from the through hole 5 to rotate relative to the pen body 1, thereby improving the fun of the pen while also improving the playability of the pen, so that the pen can be used not only for writing, but also for decompression.

[0028] In order to enhance the embellishment effect of the decorative beads 2 on the visual appearance of the pen during use, the decorative beads 2 are printed with cartoon patterns.

[0029] See also Figure 1 , Figure 2 The pen body 1 comprises an upper pen rod 11 and a lower pen rod 12, both of which are tubular structures with openings at both ends. The bottom end of the upper pen rod 11 is sleeved and detachably mounted on the top end of the lower pen rod 12, and a tip sleeve 13 is sleeved and detachably mounted on the bottom end of the lower pen rod 12. The assembled structure of the pen body 1 facilitates the assembly of the internal components of the pen body 1, and can improve the manufacturing efficiency of the pen while reducing the difficulty of manufacturing and assembling the pen.

[0030] See also Figure 1 The upper pen shaft 11 is provided with a pen clip 32, which increases the placement of the pen and improves the convenience of using the pen. The two through holes 5 are symmetrically arranged relative to the pen clip 32, ensuring the coordination of the overall appearance of the pen, thereby improving the visual effect of the pen. The lower pen shaft 12 is provided with a rubber sleeve 33, and the rubber sleeve 33 has a plurality of section structures 34 arranged at equal angles along its axis, thereby ensuring the user's grip strength on the pen.

[0031] See also Figures 2-4 The telescopic locking mechanism 4 includes a pressure rod 41 and a locking member 42. The bottom end of the pressure rod 41 is slidably arranged in the cavity of the pen body 1 along the axial direction of the pen body 1 and cannot rotate. The top end of the pressure rod 41 is exposed outside the pen body 1. The locking member 42 is slidably arranged in the cavity of the pen body 1 along the axial direction of the pen body 1. The top end of the locking member 42 is inserted from bottom to top on the bottom end of the pressure rod 41. A spring 43 is provided between the bottom end of the pen core 31 and the pen body 1. The two ends of the spring 43 respectively abut against the pen core 31 and the pen body 1. The decorative bead 2 is located between the pen core 31 and the locking member 42. The top end of the pen core 31 and the bottom end of the locking member 42 respectively abut against the two ends of the decorative bead 2 arranged in a straight line.

[0032] Wherein, a plurality of locking bars 6 are provided on the inner side surface of the pen body 1, and the locking bars 6 are arranged at equal angles around the central axis of the pen body 1. A plurality of protrusions 7 arranged at equal angles around their central axes are provided on the outer side surfaces of the pressing rod member 41 and the locking member 42. The number of the protrusions 7 is the same as that of the locking bars 6, and a sliding groove 71 for the locking bars 6 to pass through is formed between adjacent protrusions 7. First teeth 81 and second teeth 82 are provided at the top ends of the protrusions 7 on the locking member 42. The outer side surface of the first teeth 81 and the inner side surface of the second teeth 82 are both inclined surfaces 83. The bottoms of the inner side surfaces of the first teeth 81 and the second teeth 82 are connected so that a first tooth groove 84 for accommodating the bottom end of the locking bar 6 is formed between the first teeth 81 and the second teeth 82. A plurality of driving teeth 9 are provided at the bottom end of the pressing rod member 41. The driving teeth 9 are arranged in a circular ring around the central axis of the press cap and the driving teeth 9 are connected end to end. The number of the driving teeth 9 is twice that of the locking bars 6, and a second tooth groove 91 for guiding the relative rotation of the locking member 42 with respect to the pressing rod member 41 is formed between adjacent driving teeth 9.

[0033] When it is necessary to write, press the pressing rod member 41. At this time, the locking bar 6 is located in the sliding groove 71 on the locking member 42, so that the pressing rod member 41 pushes the locking member 42 to move inward, and thus the locking member 42 pushes the pen core 31 to extend out of the pen body 1 via the decorative bead 2, and the spring 43 is compressed. And during this process, when the locking bar 6 disengages from the second tooth groove 91, the locking member 42 rotates relative to the pen body 1 under the guidance of the second tooth groove 91, so that the corresponding first tooth groove 84 and the locking bar 6 are in the same straight line. Thus, after stopping pressing the pressing rod member 41, under the action of the spring 43 restoring to its original state, the pen core 31 drives the locking member 42 to move outward via the decorative bead 2, and under the guidance of the inclined surface of the inner side surface of the second tooth 82, the bottom end of the locking bar 6 enters the first tooth groove 84, achieving the purpose of the locking bar 6 restricting the locking member 42 from continuing to move outward, and thus completing the extension of the pen core 31 in the pen body 1.

[0034] After writing and using, press the pressing rod member 41 again. The spring 43 is compressed, and the pressing rod member 41 is made to push the locking member 42 to move inward and the locking bar 6 disengages from the first tooth groove 84. Then the locking member 42 rotates relative to the pen body 1 under the guidance of the second tooth groove 91, so that the first tooth 81 and the locking bar 6 are in the same straight line. Thus, after stopping pressing the pressing rod member 41, under the action of the spring 43 restoring to its original state, the pen core 31 drives the locking member 42 to move outward via the decorative bead 2, and under the guidance of the inclined surface of the outer side surface of the first tooth 81, the bottom end of the locking bar 6 enters and is inserted into the sliding groove 71 of the locking member 42, and the locking member 42 can slide outward relative to the pen body 1 to the end, thus completing the retraction of the pen core 31 into the pen body 1.
