Description

Technical Field

[0001] This utility model relates to a rotating telescopic pen. Background Technology

[0002] As a basic writing tool, pens can be categorized based on their structure into fixed pens, retractable pens, and push-button retractable pens.

[0003] Traditional retractable pens typically have a rotating and retractable mechanism at the top of the refill, allowing it to rotate and extend. Because of this mechanism, the refill is often shorter than the overall length of the pen, affecting its ink capacity. Utility Model Content

[0004] Therefore, it is necessary to provide a rotating telescopic pen that can solve the above problems.

[0005] A rotating telescopic pen includes an outer shell, an inner shell slidably fitted inside the outer shell, a pen refill slidably fitted inside the inner shell, and a reset member. The lower end of the inner shell is provided with a pen tip, and the tip of the pen refill is provided with a pen tip for penning the pen tip and protruding outside.

[0006] The outer shell includes a lower shell and an upper shell rotatably disposed on the lower shell. The upper end of the pen refill passes through the inner shell and abuts against the upper shell under the drive of the reset member.

[0007] The upper shell and the inner shell are respectively provided with matching sliders and slide rails. The slide rails extend obliquely upwards. The upper shell rotates relative to the lower shell, causing the sliders to slide along the slide rails, thereby driving the inner shell to move up and down relative to the outer shell, so that the pen tip is exposed or retracted into the pen head.

[0008] In one embodiment, the slide rail includes a first horizontal segment, a first inclined segment, and a second horizontal segment connected in sequence. The first horizontal segment is located above the second horizontal segment. When the slider slides from the first horizontal segment through the first inclined segment to the second horizontal segment, the inner shell moves upward relative to the outer shell.

[0009] In one embodiment, the slide rail further includes a second inclined section, wherein the first horizontal section, the first inclined section, the second horizontal section and the second inclined section are connected in sequence, and the second inclined section and the first horizontal section are connected.

[0010] In one embodiment, the second horizontal segment is provided with a blocking portion, which is used to prevent the slider from sliding along the slide rail.

[0011] In one embodiment, a positioning part is provided on the first horizontal segment.

[0012] In one embodiment, the slider is disposed on the side wall of the upper shell, and the slide rail is disposed on the outer side wall of the inner shell.

[0013] In one embodiment, the slide rail is protruding, and the slider abuts against the lower side of the slide rail.

[0014] In one embodiment, the slider is provided with a slot that matches the slide rail, and the upper and lower sidewalls of the slot are respectively engaged with the upper and lower sides of the slide rail.

[0015] In one embodiment, the rotary telescopic pen further includes a sleeve disposed on the inner shell and blades movably disposed on the sleeve;

[0016] Both the upper shell and the lower shell are cylindrical. The sleeve and the blade are both disposed inside the upper shell. The upper shell has an upper opening and a lower opening, and the blade is located at the upper opening.

[0017] When the upper shell rotates relative to the lower shell, the upper shell drives the blade to move relative to the sleeve, thereby causing the blade to move relative to the sleeve to close or open the upper opening. When the upper opening is closed, the upper end of the pen refill passes through the sleeve and abuts against the blade. When the upper opening is open, under the drive of the reset member, the pen refill slides relative to the inner shell, thereby causing the upper end of the pen refill to extend out from the upper opening.

[0018] In one embodiment, the sleeve near the blade and the blade near the sleeve are respectively provided with matching grooves and sliders, the groove having a first end and a second end;

[0019] When the upper shell rotates relative to the lower shell, the upper shell causes the blade to slide relative to the sleeve, thereby causing the slider to slide between the first end and the second end; when the slider slides to the first end, the sliding blade closes the upper opening; when the slider slides to the second end, the sliding blade slides open from the upper opening, thereby causing the upper opening to open.

[0020] In one embodiment, the upper shell is rotatably connected to the blade;

[0021] When the upper shell rotates relative to the lower shell, the blade rotates relative to the upper shell, thereby causing the blade to slide relative to the sleeve.

[0022] In one embodiment, the upper shell is provided with a rotating shaft, the blade is provided with a rotating hole, the rotating shaft passes through the rotating hole, and the upper shell rotates relative to the blade about the rotating shaft.

[0023] In one embodiment, the slider is disposed on the sleeve, and the groove is disposed on the blade;

[0024] When the upper opening is open, the first end is further away from the center of the sleeve than the second end.

[0025] In one embodiment, the side wall of the upper shell is provided with a through hole, and when the blade slides to the opening of the upper opening, the blade passes through the through hole and the rear part is exposed.

[0026] In one embodiment, the side wall of the upper shell is provided with a through hole, and the blade is provided with a protrusion, which is disposed in the through hole;

[0027] When the upper shell rotates relative to the lower shell, the sidewall of the through hole presses against the protrusion, thereby causing the blade to slide relative to the sleeve.

[0028] In one embodiment, the slider is disposed on the sleeve, and the groove is disposed on the blade;

[0029] When the upper opening is closed, the first end is further away from the center of the sleeve than the second end.

[0030] In one embodiment, the blade is generally triangular in shape, and the protrusion is located at one corner of the blade;

[0031] When the blade slides to the point where the upper opening opens, the protrusion is exposed after passing through the through hole.

[0032] In one embodiment, there are multiple sliding blades arranged in a ring around the upper opening.

[0033] In one embodiment, the sleeve is connected to the inner shell via a spring, and the two ends of the spring are fixedly connected to the sleeve and the inner shell respectively. The upper shell, the blade, and the sleeve abut against each other in sequence under the elastic force of the spring, and the upper end of the pen refill passes through the spring and the sleeve in sequence.

[0034] When in use, the rotating telescopic pen of this utility model is equipped with matching sliding members and slide rails on the upper shell and the inner shell, respectively, so that the inner shell can move up and down relative to the outer shell, thereby allowing the pen tip to be exposed or retracted into the pen head.

[0035] Compared with traditional retractable pens, the retractable pen of this invention does not have a retractable structure at the top of the pen refill. The upper shell, the inner shell, the slider, and the slide rail are all fitted over the pen refill, so that the length of the pen refill can be basically the same as the overall length of the retractable pen, thereby increasing the ink capacity of the pen refill.

[0060] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0061] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The present invention discloses a rotating telescopic pen according to the first embodiment, including a shell 110, an inner shell 120 slidably fitted inside the shell 110, a pen core 130 slidably fitted inside the inner shell 120, and a reset member 140. The lower end of the inner shell 120 is provided with a pen tip 122, and the tip of the pen core 130 is provided with a pen tip 132 for pen tip 132 to be exposed after pen tip 122 is inserted.

[0062] The outer shell 110 includes a lower shell 112 and an upper shell 114 rotatably disposed on the lower shell 112. The upper end of the pen refill 130 passes through the inner shell 120 and abuts against the upper shell 114 under the drive of the reset member 140.

[0063] The upper shell 114 and the inner shell 120 are respectively provided with a sliding member 116 and a slide rail 124 that match each other, with the slide rail 124 extending obliquely upward.

[0064] Combination Figures 1-6 In this embodiment, when the upper shell 114 rotates relative to the lower shell 112, it drives the slider 116 to slide along the slide rail 124, thereby driving the inner shell 120 to move up and down relative to the outer shell 110, so that the pen tip 132 is exposed or retracted into the pen tip 122.

[0065] When in use, the rotating telescopic pen of this utility model is provided with matching sliding parts 116 and sliding rails 124 on the upper shell 114 and the inner shell 120, respectively, so that the inner shell 120 can move up and down relative to the outer shell 110, thereby making the pen tip 132 exposed or retracted into the pen tip 122.

[0066] Compared with traditional retractable pens, the retractable pen of this invention does not have a retractable structure at the top of the pen core 130. The upper shell 114, inner shell 120, sliding member 116 and slide rail 124 are all fitted outside the pen core 130, so that the length of the pen core can be basically the same as the overall length of the retractable pen, thereby increasing the ink capacity of the pen core 130.

[0067] Referring to the accompanying drawings, in this embodiment, the reset member 140 is a spring sleeved on the pen refill 130. In other embodiments, the reset member 140 may also be two mutually repelling magnets or other elastic elements.

[0068] Preferably, referring to the accompanying drawings, in this embodiment, the slide rail 124 includes a first horizontal segment 1242, a first inclined segment 1244, and a second horizontal segment 1246 connected in sequence. The first horizontal segment 1242 is located above the second horizontal segment 1246. When the slider 116 slides from the first horizontal segment 1242 through the first inclined segment 1244 to the second horizontal segment 1246, the inner shell 120 moves upward relative to the outer shell 110.

[0069] More preferably, in conjunction with the accompanying drawings, in this embodiment, the slide rail 124 further includes a second inclined segment 1248, and the first horizontal segment 1242, the first inclined segment 1244, the second horizontal segment 1246 and the second inclined segment 1248 are connected in sequence, and the second inclined segment 1248 and the first horizontal segment 1242 are connected.

[0070] Specifically, referring to the accompanying drawings, in this embodiment, a blocking part 1247 is provided on the second horizontal segment 1246, and the blocking part 1247 is used to prevent the slider 116 from sliding along the slide rail 124.

[0071] The blocking part 1247 can limit the rotation of the upper shell 114 relative to the lower shell 112. On the one hand, it can prevent excessive rotation and damage to the parts, and on the other hand, it can also form a positioning.

[0072] Referring to the accompanying drawings, in this embodiment, the blocking part 1247 is a protrusion.

[0073] Specifically, referring to the accompanying drawings, in this embodiment, a positioning part 1243 is provided on the first horizontal segment 1242.

[0074] The positioning part 1243 can be used to position the pen tip 132 when it is retracted into the pen head 122.

[0075] Referring to the accompanying drawings, in this embodiment, the positioning part 1243 is a groove.

[0076] Preferably, referring to the accompanying drawings, in this embodiment, the sliding member 116 is disposed on the side wall of the upper shell 114, and the slide rail 124 is disposed on the outer side wall of the inner shell 120.

[0077] Specifically, referring to the accompanying drawings, in this embodiment, the slider 116 is embedded in the side wall of the upper shell 114. In other embodiments, the slider 116 may also be connected to the upper shell 114 in other ways.

[0078] Specifically, referring to the accompanying drawings, in this embodiment, the slide rail 124 is protruding, and the sliding member 116 abuts against the lower side of the slide rail 124.

[0079] In other embodiments, the slide rail 124 may be configured as a groove.

[0080] Combination Figure 13 Preferably, in this embodiment, the sliding member 116 is provided with a slot 1162 that matches the slide rail 124, and the upper and lower side walls of the slot 1162 are respectively engaged on the upper and lower sides of the slide rail 124.

[0081] This structural design prevents the slider 116 from detaching from the slide rail 124.

[0082] Preferably, in conjunction with the accompanying drawings, in this embodiment, the retractable pen further includes a sleeve 150 disposed on the inner shell and a blade 160 disposed on the sleeve.

[0083] Both the upper shell 114 and the lower shell 112 are cylindrical. The sleeve 150 and the blade 160 are both disposed inside the upper shell 114. The upper shell 114 has a relative upper opening 101 and a lower opening (not shown in the figure), and the blade 160 is located at the upper opening 101.

[0084] Combination Figures 14-16 Preferably, in this embodiment, when the upper shell 114 rotates relative to the lower shell 112, the upper shell 114 also drives the blade 160 to move relative to the sleeve 150, so that the blade 160 moves relative to the sleeve 150 to close the upper opening 101 or open the upper opening 101.

[0085] Referring to the accompanying drawings, in this embodiment, when the upper opening 101 is closed, the upper end of the pen core 130 passes through the sleeve 150 and abuts against the blade 160. When the upper opening 101 is open, under the drive of the reset member, the pen core 130 slides relative to the inner shell 120, thereby causing the upper end of the pen core 130 to extend outward from the upper opening 101.

[0086] Preferably, in this embodiment, the sleeve 150 near the blade 160 and the blade 160 near the sleeve 150 are respectively provided with matching sliders 152 and grooves 162, and the grooves 162 have a first end 1601 and a second end 1602.

[0087] Combination Figures 14-16 In this embodiment, when the upper shell 114 rotates relative to the lower shell 112, the upper shell 114 also drives the blade 160 to slide relative to the sleeve 150, thereby causing the slider 152 to slide between the first end 1601 and the second end 1602.

[0088] Specifically, in this embodiment, combined with Figures 4 to 12 as well as Figures 14-16 When slider 152 slides to the first end 1601, blade 160 closes the upper opening 101. At this time, the upper end of pen refill 130 passes through the inner shell 120 and sleeve 150 in sequence and abuts against blade 160, so that the upper end of pen refill 130 abuts against upper shell 114 through blade 160. When slider 152 slides to the second end 1602, blade 160 slides open from the upper opening 101, so that the upper opening 101 opens. At this time, driven by reset member 140, pen refill 130 slides relative to inner shell 120, so that the upper end of pen refill 130 protrudes out from the upper opening 101.

[0089] When this type of rotary telescopic pen is in use, the upper shell 114 rotates relative to the lower shell 112, and the upper shell 114 also drives the blade 160 to slide relative to the sleeve 150. When the slider 152 slides to the second end 1602, the blade 160 slides open from the upper opening 101, thereby opening the upper opening 101. At this time, under the drive of the reset member 140, the pen tip 130 slides relative to the inner shell 120, thereby causing the upper end of the pen tip 130 to extend out from the upper opening 101, so that the pen tip can be replaced.

[0090] Compared to traditional retractable pens that require separating the upper and lower shells to replace the refill, this new type of retractable pen only requires the upper shell 114 to rotate relative to the lower shell 112 to open the upper opening 101, making the refill replacement simpler.

[0091] In this embodiment, the upper shell 114 drives the blade 160 to slide relative to the sleeve 150 through the above structure. In other embodiments, the upper shell 114 can also drive the blade 160 to slide relative to the sleeve 150 through other means.

[0092] Preferably, in this embodiment, the side wall of the upper shell 114 is provided with a through hole 103, and the blade 160 is provided with a protrusion 164, which is disposed in the through hole 103.

[0093] When the upper shell 114 rotates relative to the lower shell 112, the side wall of the through hole 103 presses against the protrusion 164, thereby causing the blade 160 to slide relative to the sleeve 150.

[0094] More preferably, in this embodiment, the through hole 103 is elongated and extends circumferentially along the upper shell 114.

[0095] Preferably, in this embodiment, there are multiple blades 160, and the multiple blades 160 are arranged in a ring around the upper opening 101.

[0096] Referring to the accompanying drawings, specifically in this embodiment, there are 5 blades 160. In other embodiments, there may be 3, 4, 6 or more blades 160.

[0097] Referring to the accompanying drawings, in this embodiment, the blade 160 is generally triangular in shape, and the protrusion 164 is located at one corner of the blade 160.

[0098] Preferably, in conjunction with the accompanying drawings, in this embodiment, the slider 152 is disposed on the sleeve 150, and the groove 162 is disposed on the blade 160.

[0099] In other embodiments, the slider 152 may be disposed on the blade 160, and the groove 162 may be disposed on the sleeve 150.

[0100] Referring to the attached diagram, when the blade 160 slides to the opening 101, the protrusion 164 is exposed after passing through the through hole 103.

[0101] Specifically, in this embodiment, when the upper opening 101 is closed, the first end 1601 is further away from the center of the sleeve 150 than the second end 1602.

[0102] In this embodiment, the slide 162 is a blind slide; in other embodiments, the slide 162 may also be a through slide.

[0103] In this embodiment, the slide 162 is straight. In other embodiments, the slide 162 may also be curved or broken, for example, it may be arc-shaped.

[0104] Preferably, referring to the accompanying drawings, in this embodiment, the sleeve 150 is connected to the inner shell 120 by a spring 170, and the two ends of the spring 170 are fixedly connected to the sleeve 150 and the inner shell 120 respectively. The upper shell 114, the blade 160 and the sleeve 150 abut against each other in sequence under the elastic force of the spring 170, and the upper end of the pen refill 130 passes through the spring 170 and the sleeve 150 in sequence.

[0105] The upper shell 114, blade 160 and sleeve 150 abut against each other in sequence under the elastic force of spring 170, which can ensure that the slider 152 is always located in the groove 162, thus improving the overall stability.

[0106] Combination Figures 1-6 As the upper shell 114 rotates relative to the lower shell 112, the tip 132 of the pen refill 130 protrudes through the pen head 122. During this process, the side wall of the through hole 103 presses against the protrusion 164. Since the driving direction is opposite, the blade 160 cannot be driven to slide, and the upper opening 101 remains closed. At this time, the spring 170 is twisted, which acts like a torsion spring.

[0107] Combination Figure 17, Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 The present invention discloses a rotating telescopic pen according to a second embodiment, including a shell 210, an inner shell 220 slidably fitted inside the shell 210, a pen core 230 slidably fitted inside the inner shell 220, and a reset member 240. The lower end of the inner shell 220 is provided with a pen tip 222, and the tip of the pen core 230 is provided with a pen tip 232 for penetrating the pen tip 222 and protruding outside.

[0108] The outer shell 210 includes a lower shell 212 and an upper shell 214 rotatably disposed on the lower shell 212. The upper end of the pen refill 230 passes through the inner shell 220 and abuts against the upper shell 214 under the drive of the reset member 240.

[0109] The upper shell 214 and the inner shell 220 are respectively provided with a sliding member 216 and a slide rail 224 that match each other, with the slide rail 224 extending obliquely upward.

[0110] When the upper shell 214 rotates relative to the lower shell 212, it drives the slider 216 to slide along the slide rail 224, thereby driving the inner shell 220 to move up and down relative to the outer shell 210, so that the pen tip 232 is exposed or retracted into the pen tip 222.

[0111] The structure described above in the rotating telescopic pen of the second embodiment is basically the same as that in the rotating telescopic pen of the first embodiment, so it will not be described again.

[0112] Preferably, in conjunction with the accompanying drawings, in this embodiment, the retractable pen further includes a sleeve 250 disposed on the inner shell and a blade 260 disposed on the sleeve.

[0113] Both the upper shell 214 and the lower shell 212 are cylindrical. The sleeve 250 and the blade 260 are both disposed inside the upper shell 214. The upper shell 214 has a relative upper opening 201 and a lower opening (not shown in the figure), and the blade 260 is located at the upper opening 201.

[0114] Referring to the accompanying drawings, in a preferred embodiment, when the upper shell 214 rotates relative to the lower shell 212, the upper shell 214 also drives the blade 260 to move relative to the sleeve 250, thereby causing the blade 260 to move relative to the sleeve 250 to close the upper opening 201 or open the upper opening 201.

[0115] Referring to the accompanying drawings, in this embodiment, when the upper opening 201 is closed, the upper end of the pen refill 230 passes through the sleeve 250 and abuts against the blade 260. When the upper opening 201 is open, under the drive of the reset member, the pen refill 230 slides relative to the inner shell 220, thereby causing the upper end of the pen refill 230 to extend outward from the upper opening 201.

[0116] Combination Figure 23 and Figure 24 Preferably, in this embodiment, the sleeve 250 near the blade 260 and the blade 260 near the sleeve 250 are respectively provided with matching sliders 252 and grooves 262, and the grooves 262 have a first end 2601 and a second end 2602.

[0117] Referring to the accompanying drawings, in this embodiment, when the upper shell 214 rotates relative to the lower shell 212, the upper shell 214 also drives the blade 260 to slide relative to the sleeve 250, thereby causing the slider 252 to slide between the first end 2601 and the second end 2602.

[0118] Specifically, in this embodiment, referring to the accompanying drawings, when the slider 252 slides to the first end 2601, the blade 260 closes the upper opening 201. At this time, the upper end of the pen refill 230 passes through the inner shell 220 and the sleeve 250 in sequence and abuts against the blade 260, so that the upper end of the pen refill 230 abuts against the upper shell 214 through the blade 260. When the slider 252 slides to the second end 2602, the blade 260 slides open from the upper opening 201, so that the upper opening 201 opens. At this time, driven by the reset member 240, the pen refill 230 slides relative to the inner shell 220, so that the upper end of the pen refill 230 protrudes out from the upper opening 201.

[0119] When this type of rotary telescopic pen is in use, the upper shell 214 rotates relative to the lower shell 212, and the upper shell 214 also drives the blade 260 to slide relative to the sleeve 250. When the slider 252 slides to the second end 2602, the blade 260 slides open from the upper opening 201, thereby opening the upper opening 201. At this time, under the drive of the reset member 240, the pen tip 230 slides relative to the inner shell 220, thereby causing the upper end of the pen tip 230 to extend out from the upper opening 201, so that the pen tip can be replaced.

[0120] Compared to traditional retractable pens that require separating the upper and lower shells to replace the refill, this new type of retractable pen only requires the upper shell 214 to rotate relative to the lower shell 212 to open the upper opening 201, making the refill replacement simpler.

[0121] More preferably, in conjunction with the accompanying drawings, in this embodiment, the upper shell 214 is rotatably connected to the blade 260.
