Abstract
Description
Technical Field
[0001] The utility model relates to the field of stationery and file parts, in particular to a rotating telescopic pen. Background Art
[0002] Compared with capped pens, pens with retractable refills are easy to use and do not require the loss of small parts such as the cap. There are mainly two types of retractable refill pens: rotary pens and push pens. Rotary pens drive the refill to retract and retract for writing by rotating. Compared with push-type retractable pens, they have the advantages of simple operation, strong durability, and convenient control. The structural principles of common rotary refill gel pens on the market are relatively simple. They all use the tail to rotate around the axis and drive other components through the internal spiral groove to push the refill to eject the refill. This structure is difficult to process, and the processing tolerance of the arc-shaped slit is low, which makes the processing of this type of pen difficult. In addition, the overall structure of this type of pen has poor plasticity and strong structural fixity, which makes the overall structure of traditional rotary refill pens rigid and unable to meet the current users' visual function or entertainment function requirements for pens during use.

[0109] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0110] Example 1
[0111] like Figure 1-Figure 5 As shown, the rotary telescopic pen comprises a pen body 210, a pen neck 110, a rotating guide block 240, a connecting member 120, a pen neck mechanism 100, a pen body mechanism 200, a pen clip 600, a spring 80, and a pen core 90. The pen body mechanism 200 comprises a pen body 210, an axial displacement member 220, a deformable member 230, and a rotating guide block 240, and the pen neck mechanism 100 comprises a pen neck 110, a connecting member 120, and a pen tip 130. The pen core 90 is arranged in a cavity formed by the pen body 210 and the pen neck 110, and the writing end at the front end can discharge ink for writing. The front end of the pen core 90 is pressed against the front end of the pen neck 110 by the spring 80, and the pen core 90 can realize the contraction or extension of the pen tip by overcoming the elastic force of the spring 80. The pen core 90 belongs to the structure of a common pen core and therefore will not be described in detail.
[0112] When the writing end of the front of the pen core 90 extends from the nib 130 at the front end of the pen neck 110, the user can write. When the writing end of the front of the pen core 90 is retracted inside the nib 130, the pen can be stored. The rear end of the pen neck 110 includes a first contour 111, and the front end of the pen shaft 210 includes a second contour 211. The second contour 211 and the first contour 111 can rotate relative to each other, and because the first contour 111 and the second contour 211 are both wavy, it is easy to understand that when the second contour 211 rotates relative to the first contour 111, the second contour 211 can move toward or away from the first contour 111.
[0113] Optionally, the pen tip 130 may also be designed integrally with the pen neck 110 .
[0114] The pen neck 110 is a fixed part. The user can rotate the pen barrel 210 to realize the relative rotation and movement between the second contour 211 and the first contour 111. When the second contour 211 and the first contour 111 are completely staggered, there is a gap between the second contour 211 and the first contour 111, and the rotating telescopic pen is in the storage state, and the writing end is retracted to the pen tip 130; when the second contour 211 and the first contour 111 complement each other, the rotating telescopic pen is in the writing state, and the writing end extends out of the pen tip 210. A pen clip 600 is also provided at the rear end of the pen barrel 210. Specifically, in this schematic diagram, the pen clip 600 is a split structure, including a clamp body 610 and a cover body 620, wherein the clamp body 610 is inserted into the pen barrel mounting groove 214, and the clamp body 610 is arranged close to the outer wall of the pen barrel 210. The cover body 620 is fixed to the rear end surface of the pen barrel 210 from back to front. Optionally, the pen clip 600 can also be an integrated structure.
[0115] Specifically, in the above schematic diagram, the second contour 211 and the first contour 111 are wavy guide rails, and at least a portion of the two are in contact with each other during relative rotation. The first contour 111 and the second contour 211 are complementary in the writing state, and the pen shaft 210 is located at the frontmost position at this time. In the storage state, the highest points of the first contour 111 and the second contour 211 are in contact with each other, so that the pen is in a stable state.
[0116] See also Figure 7 to Figure 9 , is a schematic diagram of a pen barrel 210. The pen barrel 210 is cylindrical as a whole, and includes a wavy second contour 211 at the front end, and includes a pen barrel inner groove 212 at the rear end of the inner wall. A pen barrel boss 213 extending radially inward is provided on the inner wall between the pen barrel inner groove 212 and the second contour 211, and a pen barrel mounting groove 214 is provided at the rear end.
[0117] See also Figure 10-11 , is a schematic diagram of the assembly state of the pen neck 110 and the pen core 90, wherein the pen neck 110 includes a pen neck thread 114 near the rear end.
[0118] See also Figure 12-13 , is a schematic diagram of the shaft shifting member 220 , the outer wall of the shaft shifting member 220 includes a shaft shifting protrusion 221 , and a convex key 222 extends radially outward from the shaft shifting protrusion 221 .
[0119] Optionally, the shaft-shifting protrusion 221 may also be separated from the convex key 222 , and any convex key 222 that protrudes radially from the shaft-shifting protrusion 221 is allowed.
[0120] See also Figure 14-15 , which is a schematic diagram of a rotary guide block 240 , wherein the rotary guide block 240 includes a sliding protrusion 242 extending radially outward along the circumferential direction, and a guide surface 241 formed along the circumferential wall surface. Specifically, the guide surface 241 is spiral.
[0121] See also Figure 16 to Figure 18 As shown, the connecting member 120 includes, from back to front, a first connecting section 121, a second connecting section 122, a third connecting section 123 and a threaded section 124. The first connecting section 121, the second connecting section 122 and the third connecting section 123 are arranged in a step-like manner with increasing diameters. A stopper 126 is also included at the rear end of the first connecting section 121. The side wall also includes a slide rail 125 extending axially, and a deformation groove 127 is also provided opposite the slide rail 125.
[0122] Specifically, the connecting member 120 is made of plastic, which has a certain elasticity and can produce a certain deformation.
[0123] With reference to the accompanying drawings, it can be seen that the assembly relationship and usage of the various components of the rotary telescopic pen in Example 1 are as follows:
[0124] In the pen neck mechanism 100, the pen tip 130 and the connecting member 120 are fixedly assembled with the pen neck 110, and then the spring 80 and the pen core 90 are sequentially placed in the pen neck 110. In the pen shaft mechanism 200, the axial displacement protrusion 221 of the axial displacement member 220 is first slid into the slide rail 125 along the axial direction, and then the rotation guide block 240 is sleeved outside the first connecting section 121, wherein the maximum outer diameter of the stopper 126 is slightly larger than the inner diameter of the rotation guide block 240. During installation, since the outer wall of the stopper 126 is provided with an inclined surface 129, and a deformation groove 127 is provided opposite to the slide rail 125. It is easy to understand that when the rotation guide block 240 is pressed forward from the rear end of the connecting member 120 in the axial direction, the deformation groove 127 can shrink slightly inward, so that the rotation guide block 240 can be pushed to the outer position of the first connecting section 121. When the rotation guide block 240 completely passes through the stopper 126, the deformation groove 127 rebounds to its original position due to the elastic effect of the plastic. The rotation guide block 240 assembled to the outer periphery of the first connecting section 121 is affected by the second boss 128 of the second connecting section 122 and the stopper 126 in the axial direction, so the rotation guide block 240 can only rotate relative to the connecting member 120 and can no longer move in the axial direction. The sliding protrusion 242 of the rotation guide block 240 is slidably arranged in the inner groove 212 of the pen barrel. A deformable member 230 is disposed inside the pen holder 210 . The deformable member 230 is sleeved outside the second connecting section 122 , with one end of the deformable member 230 abutting against the rear end surface of the pen holder boss 213 and the other end of the deformable member 230 abutting against the front end surface of the rotating guide block 240 .
[0125] Optionally, the deformation member 230 is a spring.
[0126] In the storage state, the pen is in a stable state because the first contour 111 and the second contour 211 are against each other. If the user needs to write, the pen holder 210 is rotated, that is, the retractable pen is rotated from Figure 4 Towards Figure 5When the pen barrel 210 rotates, the inner groove 212 of the pen barrel also starts to rotate. At the same time, because the sliding protrusion 242 of the rotating guide block 240 is engaged in the inner groove 212 of the pen barrel, the rotating guide block 240 also starts to rotate under the drive of the pen barrel 210. However, due to the limitation of the connecting member 120, the rotating guide block 240 only rotates and does not move along the axial direction. The deformable member 230 sleeved on the outer periphery of the second connecting section 122 is slowly released from the compressed state, providing the pen barrel 210 with power to move forward, and the pen barrel 210 starts to slowly slide forward relative to the rotating guide block 240. The guide surface 241 of the rotating guide block 240 abuts against the convex key 222. When the rotating guide block 240 rotates, the guide surface 241 slides on the convex key 222 and pushes the shaft moving member 220. Since the shaft moving convex block 221 is also limited in the slide rail 125, the shaft moving member 220 moves forward in the axial direction, completing the process of converting the rotation into the axial displacement. The shaft moving member 220 abuts against the rear end of the pen core 90, pushing the pen core 90 to overcome the elastic force of the spring 80 and extend out of the pen tip 130 to enter the writing state. In the above-mentioned process of rotating the pen body 210, under the mutual guiding action of the second contour 211 and the first contour 111, the pen body 210 simultaneously rotates in the circumferential direction and moves closer to the pen neck 110, until the shapes of the two complement each other at a specific angle and return to a stable state again.
[0127] It is easy to understand that in order to ensure the stability of the overall transmission of the rotating telescopic pen, the widths of the cooperating inner groove 212 of the pen shaft and the sliding protrusion 242 should be basically the same, the widths of the slide rail 125 and the axial shift protrusion 221 should be basically the same, and the sizes of the various components of the rotating telescopic pen should be able to fit each other.
[0128] Example 2
[0129] like Figure 19-Figure 27 Shown is the structure of another embodiment of this patent.
[0130] like Figures 20-21 As shown, the connecting member 1120 includes a first connecting section 1121, a second connecting section 1122, a third connecting section 1123 and a threaded section 1124 from the back to the front, and the connecting member 1120 is fixedly connected to the pen neck 1110 by threads. The outer wall of the first connecting section 1121 is provided with a slide rail 1125. In embodiment 2, the slide rail 1125 is an arc-shaped track structure.
[0131] See also Fig.23 The deformable member 1230 is sleeved on the periphery of the first connecting section 1121 , and an elastic cantilever 1231 is provided along the outer wall of the deformable member 1230 , and the elastic cantilever 1231 can be displaced along the radial direction.
[0132] With reference to the accompanying drawings, it can be seen that the assembly relationship and usage of the various components of the rotary telescopic pen in Example 2 are as follows:
[0133] The inner wall of the pen holder 1210 includes a fixing hole (not shown in the figure), and the shaft shifting member 1220 includes a fixing key 1223. When the pen holder 1210 and the shaft shifting member 1220 are assembled, the fixing hole and the fixing key 1223 can fit together, so that the pen holder 1210 directly drives the shaft shifting member 1220, and the two can move synchronously, and then the pen neck 1110 and the connecting member 1120 are connected together. Fig.23 , Fig.28 , the deformable member 1230 is sleeved outside the first connecting section 1121, the thin section 1225 at the front end of the axial displacement member 1220 is inserted into the first connecting section 1121 and the axial displacement protrusion 1221 of the axial displacement member 1220 is abutted against the slide rail 1125, and the assembly of the pen body mechanism and the pen neck mechanism is completed.
[0134] When the user needs to switch the pen to a writing state, he rotates the pen shaft 1210, and the second contour 1211 starts to slide along the first contour 1111. The pen shaft 1210 simultaneously rotates around the axis and moves forward. At this time, the shaft moving member 1220 moves synchronously with the pen shaft 1210, and the shaft moving protrusion 1221 slides against the slide rail 1125, and the shaft moving member 1220 starts to push the pen core 90 to overcome the elasticity of the spring 80 and move forward. Figure 24 to Figure 28 As the pen holder 1210 and the axial displacement member 1220 continue to move forward, the free end of the elastic cantilever 1231 begins to contact the thick section 1224, and as the axial displacement member 1220 continues to move forward, the free end of the elastic cantilever 1231 gradually intersects with the thick section 1224 of the axial displacement member 1220. Since the outer diameter of the thick section 1224 is larger than the internal space of the elastic cantilever 1231, the elastic cantilever 1231 is stretched radially until the pen holder 1210 rotates to the front. At this time, the elastic cantilever 1231 is stretched radially to the maximum extent. At this time, an annular groove 1215 is provided on the inner wall of the pen holder corresponding to the free end of the elastic cantilever 1231. The annular groove 1215 squeezes the free end of the elastic cantilever 1231 onto the outer wall of the thick section 1224. Since the elastic cantilever 1231 receives pressure and friction at the same time, the pen is in a steady state of writing.
[0135] When the pen needs to be switched from the writing state to the storage state, it is only necessary to rotate the pen shaft in the reverse direction. Since the main pressure on the elastic cantilever comes from the annular groove 1215 in the pen shaft, when the pen shaft is rotated in the reverse direction, the deformable part can be automatically separated from the pen shaft and the axial shifting part by gently pulling while rotating.
[0136] Industrial Applicability
[0137] In summary, the utility model provides a rotary telescopic pen.
