Abstract
Description
Technical Field
[0001] The utility model relates to the field of writing utensils, in particular to a novel twist pen. Background Art
[0002] The existing methods for driving the refill to extend or retract into the pen barrel are mainly divided into pressing and twisting, wherein the twisting method is to rotate the two parts of the pen barrel relative to each other to achieve the extension or retraction of the refill. Usually, in order to improve the attractiveness of the pen, a decorative piece that moves in coordination with the refill driving method is provided on the pen. The movement mode of the decorative piece on the twisting pen is generally to move synchronously in the same direction as the refill along the axial direction of the pen barrel (that is, when the refill is extended, the decorative piece moves into the pen barrel; when the refill is retracted, the decorative piece moves out of the pen barrel), so as to change the appearance of the pen.
[0003] In this visual display method, since the shape of the decorative part is relatively fixed and it only slides relative to the pen barrel, the display effect of the decorative part's movement when the pen core switches between the extended state and the retracted state is relatively single and simple, which has limitations on improving the attractiveness of the pen. At the same time, there is a risk of aesthetic fatigue after the pen is used for a long time, which affects the usage rate of the pen. Utility Model Content

DETAILED DESCRIPTION
[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0030] See also Figure 1-Figure 8 The present embodiment is a novel twist pen, comprising a pen barrel 1 and a telescopic locking assembly 2, wherein a rotating rod 3 is rotatably provided on the pen barrel 1, a sliding seat 4 is slidably provided on the rotating rod 3 along its axial direction, a first decorative piece 41 is detachably mounted on the sliding seat 4, a rotating arm 5 is rotatably provided on the side of the rotating rod 3, a second decorative piece 51 is detachably mounted on the rotating arm 5, a transmission connection is realized between the rotating arm 5 and the sliding seat 4 via a gear rack transmission mechanism 42, the telescopic locking assembly 2 is located between the sliding seat 4 and the pen core 6 in the pen barrel 1, when the rotating rod 3 rotates relative to the pen barrel 1, the rotating rod 3 drives the pen core 6 and the sliding seat 4 to slide synchronously and in the same direction along the axial direction of the pen barrel 1 through the telescopic locking assembly 2.
[0031] When in use, the rotating rod 3 is rotated so that during the rotation of the rotating rod 3 relative to the pen barrel 1, the rotating rod 3 drives the pen core 6 and the sliding seat 4 to slide along the axial direction of the pen barrel 1 through the telescopic locking assembly 2, thereby realizing the extension or retraction of the pen core 6 on the pen barrel 1 and the sliding of the first decorative piece 41 relative to the rotating rod 3. At the same time, the sliding seat 4 can also drive the rotating arm 5 to rotate relative to the rotating rod 3 through the gear rack transmission mechanism 42 to drive the second decorative piece 51 to move, thereby achieving the purpose of the first decorative piece 41 and the second decorative piece 51 cooperating to perform active display during the switching of the pen core 6 between the extended state and the retracted state, and also realizing the change of the visual effect of the pen appearance.
[0032] In order to improve the coordinated display effect between the first decorative piece 41 and the second decorative piece 51, the appearance shapes of the first decorative piece 41 and the second decorative piece 51 can be adapted to each other. For example, the first decorative piece 41 adopts the shape of a cartoon cat head, and the second decorative piece 51 adopts the shape of a cartoon cat paw. Therefore, during the movement of the first decorative piece 41 and the second decorative piece 51, the rotating arm 5 is used as the cat's arm to create an effect of coordinated movement of the cartoon cat head and the cartoon cat paw (that is, when the cartoon cat head rises, the cat paw is raised; when the cartoon cat paw is lowered, the cat paw is put down), making the display effect more vivid, vivid and interesting.
[0033] See also Figure 1-Figure 3 The bottom end of the rotating rod 3 is sleeved and clamped on the top end of the pen holder 1 and can rotate, and a tip sleeve 11 is provided on the bottom end of the pen holder 1. The assembly structure between the pen holder 1 and the rotating rod 3 improves the convenience of assembling various components in the cavity between the pen holder 1 and the rotating rod 3, and ensures the assembly efficiency of the pen.
[0034] See also Figure 2-Figure 4 The rotating arm 5 is in an inverted L shape, the transverse section 52 of the rotating arm 5 is rotatably connected to the rotating rod 3, the longitudinal section 53 of the rotating arm 5 is parallel to the rotating rod 3, and the second decorative piece 51 is mounted and fixed on the longitudinal section 53, which ensures the coordination and unity of the pen's appearance and helps to enhance the overall sense of the pen's appearance.
[0035] In this embodiment, the second decorative member 51 and the longitudinal section 53 are connected by interference fit.
[0036] See also Figure 3 , Figure 4 The side of the rotating rod 3 is provided with a through hole 31, and the through hole 31 is provided with a ring-shaped separator 32. The separator 32 is inserted and clamped on the rotating rod 3 and cannot rotate. The rotating arm 5 is inserted on the separator 32 and can rotate. By setting the separator 32 on the rotating rod 3, the contact area between the rotating arms 5 on the rotating rod 3 after being connected is increased, the space restriction on the rotation of the rotating arm 5 relative to the rotating rod 3 is improved, and the stability of the rotation of the rotating arm 5 relative to the rotating rod 3 is ensured, thereby ensuring the display effect of the coordinated activity of the first decorative piece 41 and the second decorative piece 51 during the state switching process of the pen core 6 on the pen.
[0037] See also Figure 3-Figure 8The telescopic locking assembly 2 includes a driving seat 21, the bottom of the driving seat 21 is slidably arranged on the pen body 1 and cannot rotate, the pen core 6 is located between the pen body 1 and the driving seat 21, and a spring 61 is arranged between the bottom end of the pen core 6 and the pen body 1, and the two ends of the spring 61 are respectively against the bottom ends of the pen body 1 and the pen core 6, and the top end of the pen core 6 is inserted and against the driving seat 21, and a plurality of guide grooves 22 are opened on the top of the driving seat 21, and each guide groove 22 is arranged along the driving seat 21. Arranged on the side of the driving seat 21 at equal intervals in the circumferential direction, the bottom surface of the guide groove 22 is in the shape of an inclined surface 23 and a first locking groove 24 and a second locking groove 25 are respectively provided at both ends thereof, and the first locking groove 24 is located obliquely above the second locking groove 25. The rotating rod 3 is provided with a locking strip 26 corresponding to the guide groove 22 one by one and a limit block 27 for preventing the driving seat 21 from detaching from the top end of the rotating rod 3. The bottom end of the sliding seat 4 is sleeved and clamped on the top end of the driving seat 21.
[0038] When the pen core 6 on the pen holder 1 is in the retracted state, the rotating arm 5 is in the upward state (such as Figure 2 ) and the bottom end of the locking strip 26 is located in the second locking groove 25. The rotating rod 3 is rotated to rotate the rotating rod 3 relative to the pen body 1, so that the bottom end of the locking strip 26 is disengaged from the second locking groove 25 and moves to the first locking groove 24 under the guidance of the guide groove 22. In this process, due to the driving effect of the spring 61, the bottom end of the locking strip 26 always abuts against the drive seat 21 and pushes the drive seat 21 to move toward the pen body 1, thereby pushing the pen core 6 to extend, and compressing the spring 61, so that the pen core 6 changes from a retracted state to an extended state.
[0039] When the pen core 6 is extended, the driving seat 21 drives the sliding seat 4 to move together. At this time, while the sliding seat 4 drives the first decorative member 41 to move in the same direction, the sliding seat 4 drives the rotating arm 5 to rotate relative to the rotating rod 3 through the gear rack transmission mechanism 42, so that the rotating rod 3 changes from the upward state to the downward state (such as Figure 1 ).
[0040] When the refill 6 needs to be changed from the extended state to the retracted state again, the rotating rod 3 is rotated to reset, so that the bottom end of the locking strip 26 moves from the first locking groove 24 along the guide groove 22 to the second locking groove 25, and the driving seat 21 moves toward the rotating rod 3 under the force of the spring 61 to restore the original state, so that the refill 6 is retracted, and in this process, the sliding seat 4 is reset under the drive of the driving seat 21, so that the rotating arm 5 and the first decorative member 41 are reset.
[0041] See also Figure 4 , Figure 5 A mounting head 43 is provided on the top surface of the sliding seat 4 , and the first decorative piece 41 is sleeved and clamped on the mounting head 43 and can rotate, which facilitates the installation and replacement of the first decorative piece 41 on the sliding seat 4 .
[0042] See also Figure 5 A sliding groove 44 for sliding the limit block 27 is provided on the side of the sliding seat 4, which improves the stability of the sliding seat 4 driving the first decorative piece 41 to slide relative to the rotating rod 3, and limits the rotation of the sliding seat 4 relative to the rotating rod 3, thereby ensuring the visual display effect of the movement of the first decorative piece 41.
[0043] See also Figure 6 The driving seat 21 is provided with convex strips 71 at two opposite positions, and the driving seat 21 is slidably connected to the pen body 1 through the convex strips 71. The pen body 1 is provided with positioning holes 72 corresponding to the convex strips 71, which reduces the difficulty of corresponding assembly of the components between the pen body 1 and the rotating rod 3, thereby ensuring the accuracy of assembly and the manufacturing quality of the pen.
[0044] See also Figure 8 The bottom surface of the locking strip 26 is in an arc shape 8. When the rotating rod 3 rotates relative to the pen body 1, the difficulty of the bottom end of the locking strip 26 to disengage from the first locking groove 24 or the second locking groove 25 is reduced, ensuring that the bottom end of the locking strip 26 can move between the first locking groove 24 and the second locking groove 25 under the guidance of the guide groove 22, thereby ensuring the switching between the extended state and the retracted state of the pen core 6.
