Abstract
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, comprising:
[0006] The outer casing includes a lower casing and an upper casing rotatably disposed on the lower casing;
[0007] An inner shell is slidably fitted inside the outer shell, and the upper end of the inner shell is provided with a clamping claw;
[0008] A clamping drive component is disposed between the gripper and the housing;
[0009] A first reset member is disposed between the gripper and the housing, the first reset member being connected to the clamping drive member and the upper housing respectively; and
[0010] A pen refill that is slidably fitted inside the inner shell, the lower end of the pen refill having a pen tip;
[0011] The clamping drive moves relative to the gripper, thereby putting the gripper in a clamping state or a releasing state. When the gripper is in the clamping state, the gripper clamps and fixes the pen refill. When the gripper is in the releasing state, the pen refill can slide up and down relative to the gripper.
[0012] The upper shell and the inner shell are respectively provided with a driving part and a driving engagement part that match each other. The upper shell rotates relative to the lower shell, thereby driving the inner shell to move up and down relative to the outer shell. When the inner shell moves downward relative to the outer shell, the clamping driving member moves upward relative to the jaw, thereby making the jaw in a clamping state. The jaw clamps and fixes the pen refill. When the inner shell continues to move downward relative to the outer shell, it drives the pen refill to move downward, thereby making the pen tip exposed.
[0013] In one embodiment, the lower end of the lower shell is provided with a pen tip hole, through which the pen tip protrudes.
[0014] In one embodiment, there are at least two grippers, and the at least two grippers extend obliquely upward.
[0015] In one embodiment, the clamping drive is a sleeve fitted over the gripper.
[0016] In one embodiment, the first reset member is a spring sleeved outside the gripper, and the clamping drive member is located above the first reset member.
[0017] In one embodiment, the driving part and the driving mating part are a slider and a slide rail that cooperate with each other, and the slide rail extends obliquely upward.
[0018] In one embodiment, the slide rail includes a first positioning part, an inclined section, and a second positioning part connected in sequence;
[0019] When the slider slides to the first positioning part, the gripper clamps and fixes the pen core, and the pen tip is exposed.
[0020] When the slider slides to the second positioning part, the gripper is in a released state and the pen tip retracts.
[0021] In one embodiment, the inclined segment includes a first inclined segment, a third positioning part, and a second inclined segment connected in sequence, wherein the first positioning part, the first inclined segment, the third positioning part, the second inclined segment, and the second positioning part are connected in sequence;
[0022] When the slider slides to the third positioning part, the gripper clamps and fixes the pen core, and the pen tip retracts.
[0023] In one embodiment, the upper end of the upper shell is provided with a refill hole, and the upper end of the pen refill is used to pass through the refill hole and protrude outwards.
[0024] In one embodiment, the rotating telescopic pen further includes a second reset member, which is connected to the pen refill and the outer shell respectively. The second reset member is used to drive the upper end of the pen refill to pass through the refill hole and protrude outside.
[0025] When in use, the rotating telescopic pen of this utility model is provided with a driving part and a driving engagement part that match each other on the upper shell and the inner shell, so that the inner shell moves up and down relative to the outer shell, thereby making the pen tip protrude or retract.
[0026] 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 driving part, and the driving mating part are all fitted outside 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 storage capacity of the pen refill.

[0035] 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.
[0036] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The present invention discloses a rotating telescopic pen according to one embodiment, comprising: outer shell 10, inner shell 20, clamping drive component 30, first reset component 40 and pen core 50.
[0037] The outer casing 10 includes a lower casing 12 and an upper casing 14 rotatably disposed on the lower casing 12.
[0038] The inner shell 20 is slidably fitted inside the outer shell 10, and the upper end of the inner shell 20 is provided with a gripper 22.
[0039] The gripper 22 can be integrally formed with the inner shell 20, or it can be a separate structure set at the upper end of the inner shell 20.
[0040] The clamping drive 30 is disposed between the gripper 22 and the housing 10.
[0041] The first reset component 40 is disposed between the gripper 22 and the outer shell 10, and the first reset component 40 is connected to the clamping drive component 30 and the upper shell 14 respectively.
[0042] The pen refill 50 is slidably fitted inside the inner shell 20, and the lower end of the pen refill 50 is provided with a pen tip 52.
[0043] The clamping drive 30 moves relative to the gripper 22, thereby causing the gripper 22 to be in a clamped state or a released state. When the gripper 22 is in the clamped state, the gripper 22 clamps and fixes the pen refill 50. When the gripper 22 is in the released state, the pen refill 50 can slide up and down relative to the gripper 22.
[0044] The upper shell 14 and the inner shell 20 are respectively provided with a driving part 142 and a driving mating part 24 that match each other. The upper shell 14 rotates relative to the lower shell 12, thereby driving the inner shell 20 to move up and down relative to the outer shell 10. When the inner shell 20 moves downward relative to the outer shell 10, the clamping driving member 30 moves upward relative to the gripper 22, thereby putting the gripper 22 in a clamping state. The gripper 22 clamps and fixes the pen refill 50. When the inner shell 20 continues to move downward relative to the outer shell 10, it drives the pen refill 50 to move downward, thereby making the pen tip 52 exposed.
[0045] When this rotating telescopic pen is in use, the upper shell 14 and the inner shell 20 are respectively provided with matching driving parts 142 and driving engagement parts 24, so that the inner shell 20 can move up and down relative to the outer shell 10, thereby causing the pen tip 52 to be exposed or retracted.
[0046] Compared with traditional retractable pens, the retractable pen of this invention does not have a retractable structure at the top of the pen core 50. The upper shell 14, inner shell 20, drive part 142 and drive mating part 24 are all fitted outside the pen core 50, 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 storage capacity of the pen core 50.
[0047] Specifically, when the inner shell 20 moves upward relative to the outer shell 10, the clamping drive 30 moves downward relative to the gripper 22, which in turn drives the pen refill 50 to move upward, thereby causing the pen tip 52 to retract. When the inner shell 20 continues to move upward relative to the outer shell 10, the clamping drive 30 moves further downward relative to the gripper 22, thereby causing the gripper 22 to change from a clamped state to a released state. At this time, the pen refill 50 can slide up and down relative to the inner shell 20.
[0048] Preferably, in conjunction with the accompanying drawings, in this embodiment, the lower end of the lower shell 12 is provided with a pen tip hole 101, and the pen tip 52 is used to pass through the pen tip hole 101 and then protrude outside.

[0062] Specifically, the first positioning part 242 is located above the third positioning part 248, and the third positioning part 248 is located above the second positioning part 244.
[0063] Preferably, in conjunction with the accompanying drawings, in this embodiment, the upper end of the upper shell 14 is provided with a refill hole 102, and the upper end of the pen refill 50 is used to pass through the refill hole 102 and protrude outwards.
[0064] The upper end of the pen refill 50 is exposed after passing through the refill hole 102, which facilitates the replacement of the pen refill 50.
[0065] Specifically, when the slider slides to the second positioning part 244, the upper end of the pen refill 50 is exposed after passing through the refill hole 102. At this time, the gripper 22 is in a loose state, so that the pen refill 50 can be replaced.
