Abstract
Description
Technical Field
[0001] The utility model relates to the field of writing utensils, in particular to a rotary pen. Background Art
[0002] A rotary pen controls the extension and retraction of the refill by rotating during use. Because the refill retracts into the pen, a cap is not required. Since a rotary pen with the refill extended looks identical to a conventional pen with the cap removed (i.e., a pen with a non-retractable refill), and the exposed portion of the refill is smaller than the pen barrel, the refill may remain exposed for extended periods of time if the refill is not retracted after use. This increases the risk of damage to the refill and shortens the lifespan of the rotary pen. Utility Model Content
[0003] The purpose of the utility model is to provide a rotating pen, which can intuitively and visually reflect the status of the pen core and reduce the risk of pen damage, thereby ensuring the service life of the pen.

DETAILED DESCRIPTION
[0028] 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.
[0029] See also Figure 1-Figure 3The present embodiment provides a rotary pen, comprising a first pen body 1, a second pen body 2, and a telescopic locking mechanism 3. A refill 4 is slidably arranged in the cavity of the first pen body 1. The second pen body 2 is rotatably connected to the first pen body 1, and the central axes of the two are on the same straight line. A decorative piece 5 is slidably arranged on the second pen body 2 along its radial direction. The telescopic locking mechanism 3 drives the refill 4 and the decorative piece 5 to slide outward or inward synchronously through the relative rotation between the first pen body 1 and the second pen body 2, and the sliding directions of the two are perpendicular, that is, when the refill 4 extends outward from the first pen body 1, the decorative piece 5 extends outward relative to the second pen body 2 and separates from the second pen body 2, and when the refill 4 retracts inward into the first pen body 1, the decorative piece 5 extends inward relative to the second pen body 2 and fits with the second pen body 2.
[0030] See also Figure 2 The first pen body 1 includes a pen holder 11 and a connecting rod 12. Both the pen holder 11 and the connecting rod 12 are tubular structures with open ends. The bottom end of the connecting rod 12 is inserted into and detachably connected to the top end of the pen holder 11. The bottom end of the pen holder 11 is provided with a tip sleeve 13. The second pen body 2 is sleeved and rotatably connected to the top end of the connecting rod 12. The assembled structure of the first pen body 1 reduces the difficulty of assembling the various components within the pen, ensuring the efficiency of pen manufacturing.
[0031] In this embodiment, the pen holder 11 and the connecting rod 12 are connected via a threaded structure.
[0032] See also Figure 3-Figure 6 The telescopic locking mechanism 3 includes a pusher 31 and a driving member 32. The pusher 31 is slidably arranged on the first pen body 1 and cannot rotate. A spring 41 is provided between the bottom end of the pen core 4 and the first pen body 1. The two ends of the spring 41 respectively press against the pen core 4 and the first pen body 1. The top end of the pen core 4 presses against the pusher 31. Two locking blocks 33 are provided on the pusher 31 at equal angles around its axis. A guide groove 34 for sliding the locking block 33 is provided on the second pen body 2. The top surface of the guide groove 34 It is in the shape of an inclined surface 35 and has locking grooves 36 at both ends thereof that are adapted to the locking block 33. The driving member 32 is located between the pushing member 31 and the second pen body 2. The bottom end of the driving member 32 is inserted into the pushing member 31 from top to bottom and cannot rotate. A sliding groove 37 is provided at the top of the driving member 32. The inner end of the decorative member 5 passes through the second pen body 2 and is slidably connected to the sliding groove 37. When the pushing member 31 drives the pen core 4 to extend, the distance between the connection between the decorative member 5 and the sliding groove 37 and the edge of the driving member 32 is reduced.
[0033] The slide groove 37 includes a connected straight segment 38 and an arc segment 39. When the refill 4 on the first pen body 1 is in a retracted state, the straight segment 38 and the decorative piece 5 are in the same radial direction of the second pen body 2, and when the refill 4 on the first pen body 1 is in an extended state, the arc segment 39 and the decorative piece 5 are in the same radial direction of the second pen body 2.
[0034] When the refill 4 needs to be extended for use, the first pen body 1 and the second pen body 2 are rotated relative to each other, so that the pusher 31 rotates relative to the second pen body 2. As a result, the locking block 33 on the pusher 31 disengages from the locking groove 36 at the top of the guide groove 34 and enters the locking groove 36 at the bottom of the guide groove 34 along the guide groove 34. During this process, the pusher 31 slides relative to the first pen body 1, so that the refill 4 is extended from the first pen body 1 under the push of the pusher 31. At this time, the spring 41 is in a compressed state. At the same time, due to the rotation of the driving member 32 relative to the second pen body 2, the inner end of the decorative member 5 slides from the straight segment 38 to the arc segment 39. As the sliding groove 37 and the edge of the driving member 32 gradually approach each other, the decorative member 5 is extended outward relative to the second pen body 2 (as shown in FIG. 2 ). Figure 8 ).
[0035] On the other hand, when the refill 4 is retracted, the first pen body 1 and the second pen body 2 rotate relative to each other, causing the pusher 31 to rotate relative to the second pen body 2, so that the locking block 33 disengages from the locking groove 36 at the bottom end of the guide groove 34 and enters the locking groove 36 at the top end of the guide groove 34 along the guide groove 34, so that the refill 4 is retracted into the first pen body 1 under the force of the spring 41 to restore the original state. At the same time, the driving member 32 rotates relative to the second pen body 2, causing the inner end of the decorative member 5 to slide from the arc segment 39 to the straight segment 38. As the sliding groove 37 gradually moves away from the edge of the driving member 32, the decorative member 5 extends inward relative to the second pen body 2 (as shown in FIG. Figure 7 (as shown in
[0036] Since the sliding of the decorative member 5 relative to the second pen body 2 is mainly achieved by the setting of the slide groove 37, the positions of the straight segment 38 and the arc segment 39 of the slide groove 37 are exchanged so that the movement of the pen core 4 and the decorative member 5 can be opposite, that is, when the second pen body 2 rotates relative to the first pen body 1 and the pen core 4 retracts inward from the first pen body 1, the inner end of the decorative member 5 slides from the straight segment 38 to the arc segment 39, so that the decorative member 5 extends outward relative to the second pen body 2. Combined with the design of the decorative member 5 in the shape of a pen clip, the pen in the refill 4 retracted state can be hung or clamped by the decorative member 5.
[0037] See also Figure 4 Two sliders 51 are provided on the inner end of the decorative part 5, and there is a gap between the two sliders 51. The decorative part 5 is slidably connected to the slide groove 37 through the sliders 51, which ensures the stability of the relative sliding between the decorative part 5 and the driving part 32 and also facilitates the installation of the decorative part 5 on the driving part 32.
[0038] See also Figure 5A groove 21 for embedding the decorative piece 5 is provided on the outer surface of the second pen body 2, which ensures the stability of the position of the decorative piece 5 on the second pen body 2 when it is in the retracted state, and reduces the risk of damage to the decorative piece 5 caused by displacement due to external force when the pen is not in use.
[0039] See also Figure 5-Figure 6 The second pen body 2 is a tubular structure with a closed top and an open bottom. The end surface of the top of the second pen body 2 is in an arc shape 22, which improves the smoothness of the pen's appearance.
