Description

Technical Field

[0001] This utility model relates to the field of writing instrument technology, and in particular to a side-press writing stationery. Background Technology

[0002] Currently, writing pens are indispensable stationery in people's daily lives and work. Some types of writing pens require sealing the nib when not in use. The sealing methods generally fall into two categories: push-button writing pens and cap-type writing pens. Push-button writing pens are widely used due to their ease of operation. For example, the technical solutions disclosed in Chinese Patent Publication No. CN112406364A and Chinese Patent Announcement No. CN219055822U both use a push-button method to drive the pen tip to slide within the pen barrel, and the push-button position is at the end of the pen barrel. When the user holds the pen to write, to retract the pen tip, the user needs to move their hand position on the pen barrel and press the push-button at the end of the barrel, resulting in poor usability. Therefore, how to design a technology that allows users to press the pen tip without moving their hand to improve usability is the technical problem this utility model aims to solve.

[0051] Example 1, as Figures 1-7 As shown, this utility model provides a side-pressable writing stationery, including a pen barrel 1, a pen refill 2, and a spring 3. The pen refill 2 and the spring 3 are disposed in the pen barrel 1, and the spring 3 is disposed between the pen refill 2 and the pen barrel 1. It also includes a pressing assembly 4, which includes a positioning component 41, a sliding component 42, and a first pressing part 43. The positioning component 41 is provided with a positioning mating part 411, the sliding component 42 is provided with a positioning part 40, and the first pressing part 43 is disposed on the sliding component 42.

[0052] The positioning component 41 is fixedly mounted on the pen barrel 1, the sliding component 42 is slidably mounted on the pen barrel 1, and the pen core 2 abuts against the sliding component 42.

[0053] The pen barrel 1 has a groove 11 on its tube wall. The groove 11 extends along the sliding direction of the sliding member 42. At least part of the first pressing part 43 is disposed outside the groove 11 and exposed outside the pen barrel 1.

[0054] The push-button assembly 4 is configured to cooperate with the positioning part 40 and the positioning mating part 411 to keep the tip of the pen refill 2 extending to the outside of the pen barrel 1.

[0055] Specifically, when the user presses the first pressing part 43, the first pressing part 43 will drive the sliding part 42 to move in the pen barrel 1, and then the sliding part 42 will carry the pen core 2 towards the head of the pen barrel 1. The first pressing part 43 can meet the user's requirements for pressing the pen.

[0056] During the pressing process via the first pressing part 43, the positioning engagement part 411 on the positioning part 41 and the positioning part 40 on the sliding part 42 cooperate with each other to maintain the pen tip 21 of the pen refill 2 extending to the outside of the head of the pen barrel 1 in the writing state, thereby meeting the requirements for writing.

[0057] In actual use, to facilitate quick switching between writing and pressing modes, the first pressing part 43 can be positioned in the middle area of ​​the pen barrel 1 or in the area near the head of the pen barrel 1. This way, when the pen tip 21 of the pen refill 2 needs to be extended or retracted, the user's hand holding the pen barrel 1 can remain in the same writing grip position, facilitating operation of the first pressing part 43.

[0058] The structure for the positioning engagement part 411 of the positioning component 41 and the positioning part 40 of the sliding component 42 to achieve the pressing positioning engagement can be referred to the pressing structure in the existing pressing pen, and will not be limited or elaborated here.

[0059] In one embodiment, the pressing component 4 further includes a second pressing part 44, which is disposed on the sliding component 42 and extends to the tail of the pen barrel 1.

[0060] Specifically, in order to simultaneously satisfy the user's regular pressing operation mode of the pen, a second pressing part 44 can be provided at the tail of the pen barrel 1. The second pressing part 44 is provided on the sliding part 42. During use, the user can also press the second pressing part 44 at the tail of the pen barrel 1 to drive the pen tip 21 of the pen core 2 to extend or retract.

[0061] In one embodiment, the sliding component 42 includes a first sliding member 421 and a second sliding member 422, the first sliding member 421 and the second sliding member 422 are detachably connected together, the first sliding member 421 is provided with the positioning part 40, and the first pressing part 43 is provided on the second sliding member 422.

[0062] The pen refill 2 rests against the second slider 422.

[0063] Specifically, for ease of assembly, the sliding component 42 can be configured as a split structure. The first sliding component 421 is provided with a positioning part 40, so that the first sliding component 421 cooperates with the positioning part 41 to keep the pen tip 21 of the pen refill 2 in the state of extending out of the pen barrel 1 in the writing state.

[0064] The second slider 422 is used to support and install the first push part 43. The second slider 422 and the first slider 421 are assembled together on the pen barrel 1. By pressing the first push part 43, the second slider 422 is driven to slide, thereby driving the pen core 2 to slide in the pen barrel 1, and at the same time driving the first slider 421 to slide relative to the positioning part 41.

[0065] The first sliding component 421 and the second sliding component 422 of the split structure can be assembled onto the pen barrel 1 respectively during assembly, which solves the problem of excessive assembly difficulty caused by the overall length of the sliding component 42 being too long, and reduces the difficulty of assembly.

[0066] Furthermore, the second sliding member 422 is provided with a first engaging protrusion 423, and the first pressing part 43 is provided with a first locking groove 431. The first engaging protrusion 423 passes through the sliding groove 11 and is engaged in the first locking groove 431.

[0067] Specifically, the second slider 422 is connected to the first pressing part 43 by a snap-fit ​​method. After the second slider 422 is inserted into the pen barrel 1, the first snap-fit ​​protrusion 423 passes through the slide groove 11 to meet the requirement of connecting with the first slot 431 of the first pressing part 43.

[0068] Preferably, such as Figure 7 As shown, in order to facilitate the insertion of the second slider 422 into the pen barrel 1, the first snap-fit ​​protrusion 423 protruding from the outer wall of the second slider 422 adopts a split structure, that is, the first snap-fit ​​protrusion 423 includes a fixing member 4231 and a connecting member 4232. The fixing member 4231 and the second slider 422 are an integral structure. The fixing member 4231 protrudes from the outer wall of the second slider 422. One end of the connecting member 4232 is snapped onto the fixing member 4231, and the other end of the connecting member 4232 is snapped into the first slot 431.

[0069] Specifically, the fixing member 4231 and the second sliding member 422 are an integral structure, and the size of the fixing member 4231 protruding from the second sliding member 422 can be designed to be small. The fixing member 4231 is connected to the first pressing part 43 through the connecting member 4232. One end of the connecting member 4232 forms a groove structure to allow the end of the fixing member 4231 to be inserted into the groove structure of the connecting member 4232, and the other end of the connecting member 4232 is inserted into the first slot 431 to achieve locking.

[0070] In this way, since the size of the fixing member 4231 protruding from the outer wall of the second sliding member 422 is small, the second sliding member 422 can be easily inserted into the pen barrel 1 for assembly, thereby reducing the assembly difficulty.

[0071] Similarly, a second slot can be provided on the second sliding member 422, and a second engaging protrusion can be provided on the first pressing part 43. The second engaging protrusion passes through the sliding groove 11 and is engaged in the second slot.

[0072] Furthermore, the first sliding member 421 is provided with a snap-fit ​​part 424, and the second sliding member 422 is provided with a snap-fit ​​mating part 425, wherein the snap-fit ​​part 424 is snapped onto the snap-fit ​​mating part 425.

[0073] Specifically, the first slider 421 and the second slider 422 can also be connected by a snap-fit ​​method. For example, the snap-fit ​​part 424 is a snap-fit ​​tongue, and the snap-fit ​​mating part 425 is a snap-fit ​​groove. The snap-fit ​​tongue is snapped into the snap-fit ​​groove to achieve the snap-fit ​​of the first slider 421 and the second slider 422 together.

[0074] Furthermore, the second slider 422 is also provided with a slot 426, into which the tail of the pen refill 2 is inserted.

[0075] Specifically, in order to ensure that the second slider 422 can smoothly drive the pen refill 2 to slide, a slot 426 can be provided on the second slider 422 to assemble the pen refill 2. The tail of the pen refill 2 is inserted into the slot 426 to ensure that the pen refill 2 can smoothly follow the second slider 422 to slide.

[0076] Furthermore, the second sliding member 422 is also provided with two opposing protective plates 427, which extend toward the head of the pen barrel 1;

[0077] The pen refill 2 is sandwiched between the two protective plates 427, and the first pressing part 43 is disposed on one of the protective plates 427.

[0078] Specifically, the second slider 422 is provided with a protective plate 427 arranged opposite to it. The protective plate 427 can support the pen refill 2 on both sides to ensure that the pen refill 2 can slide smoothly with the second slider 422.

[0079] In another embodiment, in order to achieve the cooperation between the positioning component 41 and the sliding component 42 to ensure that the pen tip 21 of the pen refill 2 extends to the outside of the pen barrel 1 during the writing process, the positioning component 41 has a tubular structure, the positioning component 41 is disposed in the pen barrel 1, the positioning component 41 is provided with a guide groove 412, and the guide groove 412 is provided with a protruding positioning mating part 411;

[0080] The sliding component 42 is provided with a rotatable positioning component 45, and the positioning component 45 is provided with the positioning part 40.

[0081] Specifically, the sliding component 42 is provided with a rotatable positioning component 45, which is located in the guide groove 412 of the positioning component 41. The positioning part 40 formed by the positioning component 45 will cooperate with the positioning mating part 411 provided in the guide groove 412 to achieve positioning.

[0082] Furthermore, a rotation drive unit 413 is provided in the guide groove 412, which is used to contact the positioning part 40 to drive the positioning member 45 to rotate.

[0083] Specifically, the rotation drive unit 413 can cooperate with the positioning member 45 to realize the rotation of the positioning member 45 relative to the sliding member 42, thereby satisfying the motion requirements of the pen tip 21 of the pen refill 2 to extend and retract during the pressing process.

[0084] The structural design of setting a positioning element 45 on the sliding component 42 to cooperate with the guide groove 412 set on the positioning component 41 to meet the pressing requirements can refer to the existing technology, such as the structural design in Chinese Patent Publication No. CN112406364A, and is not limited here.

[0085] Furthermore, the inner wall of the positioning component 41 is provided with a guide protrusion 415, and the sliding component 42 is provided with a guide groove 428. The sliding component 42 is inserted into the positioning component 41, and the guide protrusion 415 is slidably disposed in the guide groove 428.

[0086] Specifically, in order to ensure that the sliding component 42 can slide smoothly relative to the positioning component 41, the sliding guide can be achieved by the cooperation of the guide protrusion 415 and the guide groove 428, so that the sliding component 42 can slide smoothly relative to the positioning component 41.

[0087] The technical solution of this utility model has the following technical effects compared with the prior art: By setting a pressing component 4 on the pen barrel 1, the first pressing part 43 of the pressing component 4 is arranged on the side of the pen barrel 1. The first pressing part 43 can satisfy the user to press on the side of the pen barrel 1, so as to drive the sliding part 42 to slide relative to the positioning part 41. In addition, during the sliding process, when the positioning mating part 411 is connected to the positioning part 40, the pen tip 21 of the pen core 2 is kept exposed outside the pen barrel 1 by the cooperation of the positioning mating part 411 and the positioning part 40. Since the first pressing part 43 is located on the side of the pen barrel 1, when the user needs to press the first pressing part 43, there is no need to adjust the hand to the tail of the pen barrel 1 to press the first pressing part 43, so as to realize the convenience of the user to perform the pressing operation without moving the hand, thereby improving the ease of use.

[0088] Example 2, based on Example 1 above, as follows Figures 8-13 As shown, the difference lies in the structure of the pressing component 4. Specifically, the pressing component 4 includes a positioning component 41 and a sliding component 42. The positioning component 41 is provided with a positioning mating part 411 and a driving mating part 412', and the sliding component 42 is provided with a positioning part 40 and a rotation driving part 46.

[0089] The positioning component 41 is rotatably mounted on the pen barrel 1, the sliding component 42 is slidably mounted on the pen barrel 1, and the pen core 2 abuts against the sliding component 42.

[0090] The push-button assembly 4 is configured to cooperate with the positioning part 40 and the positioning mating part 411 to keep the tip of the pen refill 2 extending to the outside of the pen barrel 1;

[0091] The push assembly 4 is also configured to drive the positioning component 41 to rotate via the rotation drive part 46 and the drive engagement part 412'.

[0092] Specifically, the pressing component 4 includes a positioning component 41 and a sliding component 42. The positioning component 41 is rotatably disposed in the pen barrel 1. The positioning component 41 cooperates with the sliding component 42. When the user presses the sliding component 42, the sliding component 42 will cooperate with the positioning component 41. On the one hand, the sliding component 42 drives the positioning component 41 to rotate by cooperating with the drive engagement part 412' during the up and down sliding process. On the other hand, the positioning component 41 can be positioned by the positioning engagement part 411 and the positioning part 40 when it rotates to different positions. The pen tip 2 is positioned by the sliding component 42 to ensure that the pen tip 2 is kept outside the pen barrel 1.

[0093] When the push-button pen is in writing mode, i.e., the tip of the pen refill 2 extends outside the pen barrel 1, the positioning part 40 on the sliding member 42 and the positioning mating part 411 on the positioning member 41 abut against each other. Specifically, when the user presses the sliding member 42 to extend the tip of the pen refill 2 outside the pen barrel 1 and put it in writing mode, the positioning member 41 and the sliding member 42 cooperate with each other, and the positioning mating part 411 and the positioning part 40 abut against each other to restrict the axial movement of the sliding member 42, thereby stably maintaining the extended state of the pen refill 2 and ensuring that the pen tip will not retract due to slight external force during the writing process.

[0094] During the process of rotating the positioning member 41 by pressing the sliding member 42, the rotation drive part 46 of the sliding member 42 and the drive engagement part 412' of the positioning member 41 are always in contact and will slide relative to each other. Specifically, during the process of pressing the sliding member 42, the rotation drive part 46 and the drive engagement part 412' are in contact, and the sliding member 42 drives the pen tip 2 to move towards the head of the pen barrel 1, and the pen tip 2 compresses the spring 3. After the positioning part 40 and the positioning engagement part 411 disengage, while the rotation drive part 46 and the drive engagement part 412' are in contact, the drive engagement part 412' will also rotate relative to the rotation drive part 46, so as to drive the positioning member 41 to rotate. The axial force generated on the sliding member 42 when pressed can be smoothly converted into the force driving the positioning member 41 to rotate, making the rotation of the positioning member 41 smoother.

[0095] In one embodiment, the positioning component 41 has a tubular structure, and the sliding component 42 has a rod-shaped structure;

[0096] The positioning component 41 is fitted over the sliding component 42.

[0097] Specifically, during use, when the user presses the sliding component 42, the sliding component 42 slides axially inside the positioning component 41. At this time, the inner wall of the tubular positioning component 41 forms an all-round radial constraint on the rod-shaped sliding component 42, ensuring that the sliding component 42 always moves along the axial direction of the pen barrel 1.

[0098] In one embodiment, the positioning mating part 411 and the driving mating part 412' are disposed on the inner wall of the positioning component 41;

[0099] The positioning part 40 and the rotation drive part 46 are disposed on the outer wall of the sliding member 42.

[0100] Specifically, the nesting gap between the positioning component 41 and the sliding component 42 is utilized to achieve mutual cooperation between the positioning component 41 and the sliding component 42, making the overall structure more compact. This not only helps to control the overall size of the pen barrel 1, but also enables a miniaturized design.

[0101] In one embodiment, the inner wall of the positioning component 41 is provided with a plurality of protrusions 410. Each protrusion 410 includes a limiting rib 413' and two protrusions 414'. A first surface 401, a second surface 402, a third surface 403, and a fourth surface 404 are formed sequentially around the protrusions 414'. The second surface 402 and the fourth surface 404 are arranged back to back and extend along the axis of the positioning component 41. The first surface 401 extends obliquely toward the head of the pen barrel 1, and the third surface 403 extends obliquely toward the tail of the pen barrel 1. The limiting rib 413' connects the second surface 402 of one of the protrusions 414' and the fourth surface 404 of the other protrusion 414'. The first surface 401 is the driving engagement part 412', and the limiting rib 413' is the positioning engagement part 411.

[0102] Multiple protrusions 410 are distributed around the axis of the positioning component 41, and guide grooves 415' are formed between two adjacent protrusions 410;

[0103] The positioning part 40 is a positioning rib provided on the sliding member 42, and the rotation driving part 46 is a driving rib provided on the sliding member 42.

[0104] Specifically, regarding the switching of the pen refill 2 state, when the pen is in a non-writing state, that is, when the pen tip of the pen refill 2 retracts into the pen barrel 1, the positioning ribs on the sliding component 42 are located in the guide groove 415' formed by the adjacent protruding structure 410. The guide groove 415' effectively stores and limits the positioning ribs, preventing them from wobbling freely in the non-working state and ensuring the stability of the pen refill 2 in the retracted state.

[0105] When the user presses the sliding component 42, the driving rib moves toward the first surface 401 near the protrusion 414'. During the movement, after the positioning rib disengages from the guide groove 415', the driving rib abuts against the first surface 401. As the sliding component 42 continues to move, the driving rib slides relative to the first surface 401, causing the positioning component 41 to rotate within the pen barrel 1. Due to the tilt angle design of the first surface 401, the driving rib applies a circumferential driving force to the positioning component 41 during the sliding process, causing the positioning component 41 to rotate. As the positioning component 41 rotates, the position of the guide groove 415' also changes. When the sliding component 42 is pressed to its maximum stroke, the driving rib abuts against the limiting rib 413'. After the user releases the pressure on the sliding component 42, under the rebound force of the spring 3, the positioning rib will abut against the third surface 403. Due to the inclined angle design of the third surface 403, the positioning rib and the third surface 403 cooperate to drive the positioning component 41 to continue rotating. Finally, under the action of the spring 3, the positioning rib will abut against the limiting rib 413'. At this time, the pen tip of the pen refill 2 extends, and the pen enters the writing state. The tight cooperation between the limiting rib 413' and the positioning rib stably locks this state.

[0106] When the sliding component 42 is pressed again, the driving rib moves toward the first surface 401 of the protrusion 414'. During the movement, after the positioning rib leaves the limiting rib 413' and disengages from the space between the two protrusions 414', the driving rib abuts against the first surface 401 of the other protrusion 414'. As the sliding component 42 continues to move, the driving rib slides relative to the first surface 401, allowing the positioning component 41 to rotate within the pen barrel 1. When the sliding component 42 is pressed to its maximum stroke, the driving rib abuts against the limiting rib 413'. After the user releases the pressure on the sliding component 42, under the restoring force of the spring 3, the positioning rib abuts against the third surface 403 of the other protrusion 414'. The positioning rib and the third surface 403 work together to drive the positioning component 41 to continue rotating. Finally, under the action of the spring 3, the positioning rib slides into the guide groove 415'. At this time, the tip of the pen retracts into the pen barrel 1.

[0107] In terms of force transmission, the drive rib cooperates with the first surface 401, and the positioning rib cooperates with the third surface 403 to efficiently transmit force. The inclined design of the first surface 401 and the third surface 403 cleverly transforms the axial force generated by the user pressing the sliding component 42 into the circumferential force that drives the positioning component 41 to rotate.

[0108] When the pen tip of the pen refill 2 extends outside the pen barrel 1 and is in a writing state, the positioning rib abuts against the corresponding limiting rib 413'.

[0109] With the tip of the pen retracted to the outside of the pen barrel 1, the positioning rib is located in the corresponding guide groove 415'.

[0110] When the tip of the pen refill 2 extends to the outside of the pen barrel 1 to its maximum stroke, the driving rib abuts against the corresponding limiting rib 413'.

[0111] In summary, the coordinated design of the protruding structure 410 on the positioning component 41 and the ribs on the sliding component 42 not only enables stable switching between the two states of the pen refill 2, but also ensures efficient force transmission and improves the stability of the structure.

[0112] In one embodiment, the pen barrel 1 includes a barrel 101 and a plug 102. The inner wall of the tail of the barrel 101 is provided with a stepped surface. The positioning component 41 is slidably disposed on the stepped surface. The plug 102 is provided with a through opening. The plug 102 is locked at the tail of the barrel 101 and located outside the positioning component 41. The sliding component 42 passes through the through opening.

[0113] Specifically, the separate design of the rod body 101 and the plug 102 facilitates the installation of the internal components of the pen barrel 1. During assembly, the pen refill 2, spring 3, sliding component 42, and positioning component 41 can be sequentially placed inside the rod body 101, and then the plug 102 can be snapped into the tail of the rod body 101 to complete the overall assembly, simplifying the assembly process and improving production efficiency. At the same time, the snap-fit ​​connection between the plug 102 and the rod body 101 is stable and reliable, effectively preventing the plug 102 from falling off during use and ensuring the integrity of the pen barrel 1 structure.

[0114] To facilitate user operation of the sliding component 42, a second pressing part 44 is provided on the sliding component 42. The second pressing part 44 passes through the positioning component 41 and the plug 102 and extends to the outside of the pen barrel 1. The second pressing part 44 is located at the tail of the pen barrel 1. Pressing the second pressing part 44 can drive the pen tip 2 to slide within the barrel 101. The second pressing part 44 is a snap cap integrally formed on the sliding component 42, and the positioning part 40 and the rotation drive part 46 are formed on the second pressing part 44.

[0115] Additionally, the side wall of the rod 101 may be provided with a groove 11, and the sliding component 42 is provided with a first pressing part 43. The groove 11 extends along the sliding direction of the sliding component 42, and at least part of the first pressing part 43 is provided on the outside of the groove 11 and exposed on the outside of the pen barrel 1.

[0116] The technical solution of this utility model has the following technical advantages over the prior art: By providing a positioning mating part and a driving mating part on the positioning component, and correspondingly, providing a positioning part and a driving part on the sliding component, during use, the positioning part and the positioning mating part cooperate to position the pen tip after it extends out of the pen barrel to meet the requirements of normal writing. The driving part and the driving mating part cooperate to allow the sliding component to drive the positioning component to rotate within the pen barrel. There is no need for complex structures such as guide ribs on the pen barrel; the positioning component is rotatably mounted on the pen barrel, and the sliding component is slidably mounted on the pen barrel. The positioning and driving of the pen tip can be achieved through the cooperation of the positioning mating part on the positioning component and the positioning part on the sliding component, as well as the cooperation of the driving mating part on the positioning component and the driving part on the sliding component. This greatly simplifies the pen barrel manufacturing process and reduces manufacturing costs. The push-button assembly has a simple structure, and the cooperation between the positioning component and the sliding component is concise and efficient. In the process of pen tip positioning and driving, it reduces interference between complex components, lowers the probability of jamming, and thus improves the reliability of the push-button pen, providing users with a smoother user experience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
