Description

Technical Field

[0001] The present invention relates to a stationery, in particular to a click pen with a pen clip retractable function. Background Art

[0002] Currently, writing pens (such as signature pens, ballpoint pens, and gel pens) are essential stationery items in daily life and work. To facilitate portability, writing pens are typically equipped with a clip. The clip forms a clamping space between the clip and the pen barrel, allowing the user to clip the pen to clothing. For example, Chinese Patent Publication No. CN112406365A discloses a push-button pen with a retractable clip, which can be retracted and extended according to the retractable lead. The clip is provided with a connecting portion and a pin disposed on the connecting portion. Correspondingly, a sliding member is provided in the pen barrel, and a limit slot is disposed on the sliding member. The pin slides within the limit slot to allow the clip to be retracted and extended. Typically, when the lead is retracted, the clip is extended, making it easy to clip to clothing. However, during use, the extended clip is maintained by the abutment of the pin and the limit slot. When the pen clip is squeezed by external force, the pin shaft is easily disengaged from the limiting slide slot, causing the pen clip to fall off the pen holder, resulting in low reliability. In view of this, how to design a click pen that improves reliability and enhances user experience is the technical problem to be solved by the present invention. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] Example 1, as Figures 1 to 8 As shown, an embodiment of the present application provides a click pen, comprising:

[0047] A pen holder 1, wherein a pen tip 11 is provided at the head of the pen holder, a first mounting opening 12 is provided at the tail of the pen holder, and a second mounting opening 13 is provided on the side wall of the pen holder;

[0048] A pen refill 2, wherein the pen refill is provided with a pen tip 21 and is disposed in the pen barrel;

[0049] a pen cap 4, the pen cap being movably disposed in the first mounting opening;

[0050] a spring 5, which is disposed in the pen barrel and configured to drive the pen core to reset;

[0051] A driving assembly, comprising a sliding component 3, the sliding component being slidably disposed in the pen holder, and having an inclined surface 30;

[0052] The retractable clip assembly 6 comprises a pen clip 61, a connecting frame 62, and an elastic member 63. The pen clip is provided with a connecting portion 611, a mounting channel is formed between the connecting frame and the connecting portion, and the connecting frame is further provided with a pressure rod 621, which is located in the mounting channel; the connecting frame is provided with a plug hole (not marked), the connecting portion is provided with a connecting post (not marked), and the connecting frame is located between the elastic member and the pen clip; the connecting portion is inserted into the second mounting opening, the connecting frame is located on the pen barrel, the plug hole and the second mounting opening are arranged opposite each other, the connecting post is inserted into the plug hole and has an interference fit with the plug hole, and the elastic member is clamped between the connecting frame and the inner wall of the pen barrel;

[0053] Wherein, the sliding component passes through the installation channel, and the inclined surface abuts against the pressure rod; the pen cap is connected to the sliding component and is configured to drive the sliding component to slide in the pen body.

[0054] Specifically, the connecting frame is assembled into the pen barrel, such that the elastic member is sandwiched between the inner wall of the pen barrel and the connecting frame. The pressure rod on the connecting frame is capable of engaging with the inclined surface formed by the sliding component. During use, the user drives the sliding component to slide within the pen barrel via the pen cap, causing the sliding component to move toward the pen tip of the pen barrel to extend the pen refill. At this time, the inclined surface presses on the pressure rod, causing the connecting frame to drive the pen clip closer to the pen barrel, at which point the pen clip is in a retracted state.

[0055] When the sliding member slides in the opposite direction, the inclined surface tends to move away from the pressure rod. The elastic member allows the pressure rod on the connecting frame to remain in contact with the inclined surface. After the refill retracts, the elastic member allows the pen clip to extend outside the pen holder. In this state, if the pen clip is squeezed by an external force, the force applied will overcome the elastic member and retract it into contact with the pen holder.

[0056] The connecting portion is a connecting plate provided on both sides of the pen clip, connecting columns are provided on the connecting plate, the cross section of the connecting frame is a U-shaped structure, and the two sides of the connecting frame are respectively provided with the plug holes.

[0057] In addition, a first positioning groove is provided on the inner wall of the pen barrel, a second positioning groove is provided on the connecting frame, one end of the elastic member is located in the first positioning groove, and the other end of the elastic member is located in the second positioning groove.

[0058] A pressure rod is provided on the connecting frame, and an inclined surface is formed on the corresponding sliding component. When the sliding component slides in the pen barrel toward the pen tip, the inclined surface presses on the pressure rod to retract the pen clip. After the sliding component slides in the opposite direction, the pressure rod is also pressed against the inclined surface under the action of the elastic component, and the pen clip is extended. At this time, the pen clip in the extended state will retract under the action of force, overcoming the elastic force of the elastic component, thereby preventing the pen clip from falling off or being damaged due to excessive force. The pen clip can be retracted under force when it is released, thereby improving the reliability of use and enhancing the user experience.

[0059] By providing a connecting column on the pen clip and a plug hole on the connecting frame, after the connecting frame is assembled into the pen barrel, the plug hole and the second mounting opening are arranged opposite each other. In this way, when assembling the pen clip, the operator can align the connecting column with the plug hole through the second mounting opening to ensure assembly accuracy.

[0060] Furthermore, the inclined surface is extended toward the pen tip and away from the inner wall of the pen shaft.

[0061] Furthermore, the pen cap is rotatably arranged in the first mounting opening, the sliding component abuts against the end of the pen core, a driving part 40 is provided in the pen cap, and a first pushing part 31 is further provided on the sliding component;

[0062] In which, the driving part is configured to cooperate with the first pushing part to drive the sliding component to slide in the pen shaft when the pen cap rotates along a first direction so that the pen tip extends from the pen head; the driving part is also configured to abut against the pushing part when the pen cap rotates along a second direction and the pen core and the sliding component are driven by the spring to reset so that the pen tip retracts into the pen head; the first direction and the second direction are set in opposite directions.

[0063] Specifically, by rotating the pen cap, the driving portion 40 and the first pushing portion 31 cooperate to drive the sliding member to move within the pen body. The driving portion 40 can be a raised structure, while the first pushing portion 31 can be an inclined guide surface formed on the sliding member; alternatively, the driving portion 40 can be an inclined guide surface formed in the pen cap, while the first pushing portion 31 can be a raised structure formed on the sliding member.

[0064] Example 2, as Figures 9 to 15 As shown, based on the above-mentioned embodiment 1, the present application can also use a pressing method to achieve the extension and retraction of the pen core 2. In order to meet the user's choice of whether the click pen produces a clicking sound during use, the embodiment of the present application makes the following structural improvements to the click pen.

[0065] A plurality of guide ribs 14 are provided on the inner wall of the pen barrel 1 near the tail portion. The guide ribs 14 extend along the length of the pen barrel 1 , and guide grooves are formed between two adjacent guide ribs 14 .

[0066] The pen cap 4 includes a cap body 41 and an adjusting component 42. The cap body 41 is provided with a driving part 40. The cap body 41 is rotatably disposed in the first mounting opening 12. The adjusting component 42 is further provided with a second pushing part 421. The driving part 40 and the second pushing part 421 abut against each other.

[0067] The driving assembly includes a sliding component 3 and a rotating component 32. The sliding component 3 is a hollow structure and a first tooth structure is provided on the circumference of the sliding component 3. The rotating component 32 is provided with a second tooth structure. The first tooth structure and the second tooth structure are arranged opposite to each other.

[0068] The sliding component 3 is slidably disposed in the pen holder 1 along the guide rib 14 , and the rotating component 32 can rotate in the pen holder 1 and slide along the guide rib 14 ; the sliding component 3 and the rotating component 32 are sleeved on the adjusting component 42 ;

[0069] The cap body 41 is rotatably disposed on the sliding component 3 , and the driving portion 40 is configured to cooperate with the second pushing portion 421 to convert the rotational motion of the cap body 41 into the sliding motion of the adjusting component 42 ;

[0070] The end of the adjusting component 42 opposite to the pen barrel 1 is the adjusting end, and the end surface of the adjusting end selectively extends to the outside of the rotating component 32.

[0071] Specifically, the pen cap is mounted on the first mounting opening 12 of the pen body 1, and the cap body 41 is disposed in the first mounting opening 12. The user presses the cap body 41 to drive the pen refill 2 to slide in the pen body 1. The cap body 41 is provided with an adjustment member 42. The rotation of the cap body 41 cooperates with the driving portion 40 and the second pushing portion 421 to enable the adjustment member 42 to slide relative to the sliding member 3.

[0072] By adjusting the position of the adjusting component 42 , the adjusting end of the adjusting component 42 can be extended from the rotating component 32 , or the adjusting end of the adjusting component 42 can be retracted into the rotating component 32 .

[0073] Among them, when the end surface of the adjusting end of the adjusting component 42 extends to the outside of the rotating component 32, the pen core 2 is in a retracted state, and the adjusting end of the adjusting component 42 rests on the pen core 2; when the end surface of the adjusting end of the adjusting component 42 retracts to the inside of the rotating component 32, the pen core 2 is in a retracted state, and the rotating component 32 rests on the pen core 2.

[0074] The different positions of the adjustment component 42 can realize the user to produce a pressing sound or realize a silent pressing when pressing the cap body 41. The following is a detailed description with reference to the accompanying drawings.

[0075] like Figures 9 and 10 As shown, when the user operates the click pen to produce a click sound, the cap 41 rotates, causing the adjustment end of the adjustment member 42 to retract into the interior of the rotating member 32. Taking the refill 2 of the click pen in its retracted state as an example, when the user presses the cap 41, the cap 41 drives the sliding member 3 to slide along the guide rib 14 toward the pen tip 11. Simultaneously, the sliding member 3 abuts against the rotating member 32, causing the rotating member 32 to also slide along the guide rib 14. Before the rotating member 32 disengages from the guide rib 14, it can only slide within the pen barrel 1. During this sliding process, the rotating member 32 directly abuts against the refill 2, driving the refill 2 to slide. When the rotating member 32 disengages from the guide rib 14, the refill 2 moves a short distance in the opposite direction under the action of the spring 5, driving the rotating member 32 in the opposite direction, causing the first and second tooth structures to engage, producing the click sound. Among them, the click pen has a click sound state, and the mutual cooperation between the sliding part 3 and the rotating part 32 can refer to the conventional click pen and will not be described here.

[0076] like Figures 11 to 12As shown, when the user operates the pen without making a sound, the cap body 41 rotates so that the adjusting end of the adjusting member 42 extends out of the rotating member 32. When the user presses the cap body 41, the cap body 41 drives the sliding member 3 to slide along the guide rib 14 toward the pen tip 11. At the same time, the sliding member 3 abuts against the rotating member 32, so that the rotating member 32 also slides along the guide rib 14. Before the rotating member 32 is separated from the guide rib 14, the rotating member 32 can only slide in the pen body 1. During the sliding process, the rotating member 32 does not contact the end of the refill 2. Instead, the adjusting end of the adjusting member 42 abuts against the refill 2, driving the refill 2 to slide. When the rotating member 32 detaches from the guide rib 14, the adjusting end of the adjusting member 42 abuts against the refill 2, preventing the refill 2 from moving in the opposite direction a short distance under the action of the spring 5. As a result, the rotating member 32 does not rotate immediately after detaching from the guide rib 14. Instead, the sliding member 3 must continue to move, relying on the tooth surfaces of the first and second tooth structures to cooperate to drive the rotating member 32. This avoids the clicking noise caused by the spring 5 causing the rotating member 32 to move in the opposite direction. When the user releases the pen, the spring 5 causes the refill 2 to move in the opposite direction, simultaneously abutting against the rotating member 32 and the adjusting member 42. Ultimately, the rotating member 32 is stuck in the guide rib 14, keeping the pen tip 21 exposed.

[0077] It should be noted that the silent pressing of the click pen described in this application only means that the pressing sound is smaller than that of a conventional click pen, so as to achieve an almost silent state within the range of human hearing.

[0078] By arranging an adjusting component 42 on the cap body 41, the adjusting component 42 can be driven by the cap body 41 to slide relative to the sliding component 3. The adjusting component 42 rotates the cap body 41 according to the user's requirement on whether there is a pressing sound when pressing. When the user requires silent pressing, the cap body 41 drives the end face of the adjusting end of the adjusting component 42 to extend to the outside of the rotating component 32. In this way, when the cap body 41 is pressed to drive the pen core 2 to move so that the pen tip 21 extends to the outside of the pen head 11, the adjusting end of the adjusting component 42 abuts against the pen core 2. After the rotating component 32 is detached from the guide rib 14, since the rotating component 32 does not apply external force to the pen core 2, the spring 5 can be avoided. The action causes the rotating part 32 to move in the opposite direction due to the external force of the pen core 2, thereby producing a sound to achieve silent pressing; conversely, the cap body 41 rotates in the opposite direction so that the adjusting end of the adjusting part 42 retracts into the inside of the rotating part 32. In this way, when the cap body 41 is pressed to drive the pen core 2 to move and extend, the rotating part 32 rests on the pen core 2. After the rotating part 32 is disengaged from the guide rib 14, under the action of the spring 5, the pen core 2 will drive the rotating part 32 to move in the opposite direction and get stuck at the end of the guide rib 14, thereby producing a pressing sound, so that the user can adjust the click pen to have a pressing sound or silent pressing according to needs, thereby meeting the usage requirements of different users to improve the user experience.

[0079] Furthermore, a side wall of the adjusting end portion of the adjusting component 42 is provided with an elastic deformation portion 422 , and the elastic deformation portion 422 abuts against the inner wall of the rotating component 32 .

[0080] Specifically, by providing an elastic deformation portion 422 on the adjusting end of the adjusting component 42, the rotating component 32 can be prevented from rotating arbitrarily at the moment of separation from the guide rib 14 when the adjusting end is in the state, thereby ensuring that the rotating component 32 can achieve directional rotation through the cooperation of the tooth structure, thereby improving the reliability of use.

[0081] Furthermore, the sliding component 3 is formed with a first through hole, and the adjusting component 42 can slide in the first through hole, and the adjusting component 42 cannot rotate in the first through hole. For this reason, the cross-section of the first through hole is non-circular, and the cross-sectional shape of the part where the adjusting component 42 slides in cooperation with the first through hole is the same as the inner contour of the first through hole.

[0082] In addition, the rotating member 32 is formed with a second through hole, and the cross section of the second through hole is circular. In this way, the elastic deformation portion 422 can rotate freely relative to the second through hole to improve the smoothness of the pressing.

[0083] Furthermore, a limiting portion 15 is provided in the pen body 1 , and the rotating component 32 is located between the limiting portion 15 and the sliding component 3 ; the limiting portion 15 is configured to limit the sliding of the rotating component 32 during the rotation of the rotating component 32 .

[0084] Specifically, in order to limit the movement of the rotating member 32 after it has separated from the guide rib 14 and ensure smooth rotation of the rotating member 32, the pen holder 1 includes a stopper 15 to limit the rotating member 32. Furthermore, after the rotating member 32 abuts against the stopper 15, the stopper 15 can support the rotating member 32 in rotation.

[0085] The limiting portion 15 is an annular rib formed on the inner wall of the pen barrel 1 ; or, the limiting portion 15 is a limiting sleeve, which is clamped in the pen barrel 1 .

[0086] In another embodiment, the specific entities of the driving portion and the second pushing portion may have various structural forms, which will be described in conjunction with the accompanying drawings.

[0087] In one embodiment, the second pushing portion 421 is a first protruding structure formed on the adjusting component 42 , and the driving portion 40 is a first inclined guide surface formed on the inner wall of the cap body 41 , and the first protruding structure abuts against the first inclined guide surface.

[0088] Specifically, the adjustment member 42 is provided with a raised first protrusion structure, such as a rib or a bump. A first inclined guide surface is formed on the inner wall of the hollow structure formed by the cap body 41. The first inclined guide surface and the first protrusion structure abut against each other, so that when the cap body 41 is rotated in the first direction, the pressure exerted by the rotating first inclined guide surface on the first protrusion structure is converted into linear sliding motion of the adjustment member 42, thereby driving the adjustment member to move by rotating the cap body 41.

[0089] The first inclined guide surface is spirally arranged around the axis of the cap body 41 .

[0090] In addition, in order to limit the rotation angle of the cap body 41, the inner wall of the cap body 41 is further provided with a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion extending along the axial direction of the cap body 41; the first limiting portion is located outside the inner end portion of the first inclined guide surface, and the second limiting portion is located outside the outer end portion of the first inclined guide surface;

[0091] The first limiting portion and the second limiting portion are respectively configured to cooperate with the second pushing portion 421 to limit the rotation angle of the cap body 41 .

[0092] Specifically, during the rotation of the cap body 41, the first limiting portion, the second limiting portion and the first inclined guide surface rotate together, and when the first limiting portion or the second limiting portion abuts against the first protruding structure, the cap body 41 can be restricted from continuing to rotate.

[0093] The first limiting portion and the second limiting portion may be positioning vertical surfaces formed inside the cap body 41 , and the positioning vertical surfaces are distributed on both sides of the first inclined guide surface.

[0094] Furthermore, a first plug-in rod is provided at the end of the adjusting component 42 , the first protrusion structure is formed on the rod wall of the first plug-in rod, and the free end of the first plug-in rod is inserted into the cap body 41 .

[0095] Specifically, in order to facilitate, quickly and accurately assembly, a first plug-in rod is provided at the end of the adjusting component 42, and a first protrusion structure is formed on the first plug-in rod. During the assembly process, the free end of the first plug-in rod can be inserted into the cap body 41 so that the first protrusion structure is in contact with the first inclined guide surface.

[0096] In another embodiment, the protruding structure and the inclined guide surface can be interchanged, such as Figures 10 and 11 As shown, the second pushing portion 421 is a second inclined guide surface formed on the adjusting component 42, and the driving portion 40 is a second protruding structure formed on the inner wall of the pen cap 4, and the second protruding structure abuts against the second inclined guide surface.

[0097] Specifically, different from the above embodiment, a second inclined guide surface is formed on the adjusting component 42 , and a second protruding structure is formed in the pen cap 4 .

[0098] Likewise, the second protruding structure may be a rib or a protrusion formed on the inner wall of the pen cap 4 .

[0099] During use, the pen cap 4 drives the second protruding structure to rotate, and the second protruding structure will slide along the second inclined guide surface, so that the adjusting component 42 slides in the pen barrel 1.
