DETAILED DESCRIPTION

[0022] Example 1, as Figure 1-Figure 7 As shown, the present invention provides a side-pressed writing stationery, comprising a pen holder 1 and a pen core 2 , wherein the pen core 2 is arranged in the pen holder 1 .

[0023] The side-press writing stationery further includes a press assembly 4, which includes a positioning component 41, a sliding component 42, and a first press portion 43. The positioning component 41 is provided with a positioning matching portion 411, the sliding component 42 is provided with a positioning portion 40, and the first press portion 43 is provided on the sliding component 42. The positioning component 41 is fixedly arranged on the pen holder 1 , the sliding component 42 is slidably arranged on the pen holder 1 , and the pen core 2 rests on the sliding component 42 ; A sliding groove 11 is provided on the wall of the pen barrel 1 , and the sliding groove 11 extends along the sliding direction of the sliding member 42 . At least a portion of the first pressing portion 43 is provided outside the sliding groove 11 and exposed outside the pen barrel 1 . The pressing assembly 4 is configured to keep the tip of the pen core 2 extending out of the pen barrel 1 through the cooperation between the positioning portion 40 and the positioning matching portion 411 .

[0024] Specifically, when the user presses the first pressing part 43 by hand, the first pressing part 43 will drive the sliding part 42 to move in the pen body 1, and then move the pen core 2 toward the head of the pen body 1 through the sliding part 42. The first pressing part 43 can meet the user's requirements for pressing the pen.

[0025] During the process of pressing the first pressing portion 43, the positioning matching portion 411 on the positioning component 41 cooperates with the positioning portion 40 on the sliding component 42 to maintain the pen tip 21 of the pen core 2 extending to the outside of the head of the pen shaft 1 in the writing state, thereby meeting the requirements of writing use.

[0026] The side-press writing stationery further comprises a spring 3, which is arranged in the pen holder 1 and between the pen core 2 and the pen holder 1. The spring 3 applies elastic force to the pen core 2 to meet the requirement of automatic retraction of the pen core 2.

[0027] In actual use, in order to facilitate the user to quickly switch between the writing state and the pressing operation state, the first pressing portion 43 can be arranged in the middle area of ​​the pen body 1 or the area close to the head of the pen body 1. In this way, when the user needs to extend or retract the pen tip 21 of the pen refill 2 during use, the user's hand holding the pen body 1 can remain in the writing grip position, making it convenient for the user to operate the first pressing portion 43.

[0028] Among them, for the structural form of the positioning matching portion 411 of the positioning component 41 and the positioning portion 40 of the sliding component 42 to achieve press-to-position matching, reference can be made to the press structure of the press pen in the prior art, and no limitation or redundant description is made here.

[0029] In one embodiment, the pressing assembly 4 further includes a second pressing portion 44 , which is disposed on the sliding component 42 and extends to the rear end of the pen barrel 1 .

[0030] Specifically, in order to simultaneously meet the user's conventional pressing operation method of the pen, a second pressing part 44 can be provided at the tail of the pen shaft 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 shaft 1 to drive the pen tip 21 of the pen core 2 to extend or retract.

[0031] 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 portion 40 , and the first pressing portion 43 is provided on the second sliding member 422 . The pen core 2 rests on the second sliding member 422 .

[0032] Specifically, in order to facilitate assembly, the sliding component 42 can be set as a split structure, and a positioning portion 40 is provided on the first sliding component 421, so that the first sliding component 421 cooperates with the positioning component 41 to maintain the pen tip 21 of the pen core 2 in a state of extending out of the pen shaft 1 when writing.

[0033] The second sliding member 422 is used to support and install the first pressing part 43. The second sliding member 422 and the first sliding member 421 are assembled together on the pen body 1. By pressing the first pressing part 43, the second sliding member 422 is driven to slide, thereby driving the pen core 2 to slide in the pen body 1, and at the same time driving the first sliding member 421 to slide relative to the positioning component 41.

[0034] The first sliding member 421 and the second sliding member 422 of the split structure can be assembled to the pen body 1 respectively during assembly, thereby solving the problem of the overall length of the sliding member 42 being too long and causing excessive assembly difficulty, thereby reducing the difficulty of assembly.

[0035] Furthermore, a first engaging protrusion 423 is provided on the second sliding member 422 , and a first engaging groove 431 is provided on the first pressing portion 43 . The first engaging protrusion 423 passes through the sliding groove 11 and is engaged in the first engaging groove 431 .

[0036] Specifically, the second sliding member 422 is connected to the first pressing portion 43 by a snap-fitting manner. After the second sliding member 422 is inserted into the pen body 1, the first snap-fitting protrusion 423 passes through the slide groove 11 to meet the requirement of connecting with the first snap-fitting groove 431 of the first pressing portion 43.

[0037] Preferably, if Figure 7 As shown, in order to facilitate the installation of the second sliding member 422 into the pen body 1, the first clamping protrusion 423 protruding from the outer wall of the second sliding member 422 adopts a split structure, that is, the first clamping protrusion 423 includes a fixing member 4231 and a connecting member 4232, and the fixing member 4231 and the second sliding member 422 are an integrated structure. The fixing member 4231 is protruded on the outer wall of the second sliding member 422, and one end of the connecting member 4232 is clamped on the fixing member 4231, and the other end of the connecting member 4232 is clamped in the first clamping groove 431.

[0038] Specifically, the fixing member 4231 and the second sliding member 422 are integrally formed, and the protrusion of the fixing member 4231 from the second sliding member 422 can be designed to be relatively small. The fixing member 4231 is connected to the first pressing portion 43 via the connecting member 4232. One end of the connecting member 4232 is formed with a groove structure to allow the end of the fixing member 4231 to snap into the groove structure of the connecting member 4232. The other end of the connecting member 4232 is inserted into the first slot 431 for snap-fitting.

[0039] 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 body 1 for assembly, thereby reducing the difficulty of assembly.

[0040] Similarly, a second clamping groove may be provided on the second sliding member 422 , and a second clamping protrusion may be provided on the first pressing portion 43 . The second clamping protrusion passes through the sliding groove 11 and is clamped in the second clamping groove.

[0041] Furthermore, a clamping portion 424 is provided on the first sliding member 421 , and a clamping fitting portion 425 is provided on the second sliding member 422 . The clamping portion 424 is clamped on the clamping fitting portion 425 .

[0042] Specifically, the first sliding member 421 and the second sliding member 422 can also be connected by a snap-fitting manner, for example: the snap-fitting portion 424 is a latch, and the snap-fitting portion 425 is a slot, and the latch is clipped into the slot to achieve the snap-fitting of the first sliding member 421 and the second sliding member 422 together.

[0043] Furthermore, a slot 426 is provided on the second sliding member 422 , and the tail of the pen core 2 is inserted into the slot 426 .

[0044] Specifically, in order to ensure that the second sliding member 422 can smoothly drive the pen core 2 to slide, a slot 426 can be provided on the second sliding member 422 to assemble the pen core 2, and the tail of the pen core 2 is inserted into the slot 426 to ensure that the pen core 2 can smoothly follow the sliding of the second sliding member 422.

[0045] Furthermore, the second sliding member 422 is further provided with two oppositely arranged guard plates 427, and the guard plates 427 extend toward the head of the pen barrel 1; The pen core 2 is clamped between the two guard plates 427 , and the first pressing portion 43 is provided on one of the guard plates 427 .

[0046] Specifically, the second sliding member 422 is provided with opposing guard plates 427 , which can support the pen core 2 on both sides of the pen core 2 to ensure that the pen core 2 can slide smoothly following the second sliding member 422 .

[0047] In another embodiment, in order to achieve the cooperation between the positioning member 41 and the sliding member 42 to ensure that the pen tip 21 of the pen core 2 extends out of the pen body 1 in the writing state during the pressing process, the positioning member 41 is a tubular structure, the positioning member 41 is arranged in the pen body 1, and a guide groove 412 is provided on the positioning member 41, and the protruding positioning matching portion 411 is provided in the guide groove 412; The sliding member 42 is provided with a rotatable positioning member 45 , and the positioning portion 40 is provided on the positioning member 45 .

[0048] Specifically, a rotatable positioning member 45 is provided on the sliding member 42, and the positioning member 45 is provided in the positioning member 41 and the guide slot 412. The positioning portion 40 formed by the positioning member 45 cooperates with the positioning matching portion 411 provided in the guide slot 412 to achieve positioning.

[0049] Furthermore, a rotation driving portion 413 is provided in the guide slot 412 , and the rotation driving portion 413 is used to contact the positioning portion 40 to drive the positioning member 45 to rotate.

[0050] 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 movement requirements of the positioning member 45 rotating to switch different postures during the pressing process to meet the extension and retraction of the pen tip 21 of the pen core 2.

[0051] Among them, the structural design of the positioning member 45 provided on the sliding component 42 to cooperate with the guide groove 412 provided 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.

[0052] Furthermore, a guide protrusion 415 is provided on the inner wall of the positioning component 41 , and a guide groove 428 is provided on the sliding component 42 . The sliding component 42 is inserted into the positioning component 41 , and the guide protrusion 415 is slidably provided in the guide groove 428 .

[0053] Specifically, in order to ensure that the sliding component 42 can slide smoothly relative to the positioning component 41, the guide protrusion 415 and the guide groove 428 can cooperate with each other to achieve sliding guidance, so that the sliding component 42 can slide smoothly relative to the positioning component 41.

[0054] The technical solution of the present invention has the following technical effects compared with the prior art: by arranging 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, and the first pressing part 43 can satisfy the user's need to press the side of the pen barrel 1, so as to drive the sliding part 42 to slide relative to the positioning part 41 through the first pressing part 43, and, during the sliding process, when the positioning matching part 411 is connected to the positioning part 40, the positioning matching part 411 can cooperate with the positioning part 40 to maintain the pen tip 21 of the pen refill 2 exposed outside the pen barrel 1, and 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, he does not need to adjust his hand to the tail of the pen barrel 1 to press the first pressing part 43, so that the user can perform the pressing operation without moving his hand to improve the convenience of use.

[0055] Example 2, based on the above example 1, as Figures 8-13 As shown, the difference lies in the structure of the push assembly 4. Specifically, the push assembly 4 includes a positioning component 41 and a sliding component 42. The positioning component 41 is provided with a positioning matching portion 411 and a driving matching portion 412', and the sliding component 42 is provided with a positioning portion 40 and a rotation driving portion 46. The positioning component 41 is rotatably disposed on the pen holder 1 , the sliding component 42 is slidably disposed on the pen holder 1 , and the pen core 2 rests against the sliding component 42 ; The pressing assembly 4 is configured to keep the tip of the pen core 2 extending out of the pen barrel 1 through the cooperation between the positioning portion 40 and the positioning matching portion 411; The push assembly 4 is further configured to drive the positioning component 41 to rotate through the cooperation between the rotation driving portion 46 and the driving cooperation portion 412 ′.

[0056] Specifically, the pressing assembly 4 includes a positioning component 41 and a sliding component 42. The positioning component 41 is rotatably arranged in the pen body 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 rotating the driving part 46 and the driving matching part 412' during the up and down sliding process. On the other hand, when the positioning component 41 rotates to different positions, the sliding component 42 can be positioned by the positioning matching part 411 and the positioning part 40. The pen refill 2 is positioned by the sliding component 42 to ensure that the pen tip of the pen refill 2 remains outside the pen body 1.

[0057] When the push-button pen is in the writing state, that is, when the tip of the refill 2 is extended outside the pen barrel 1, the positioning portion 40 on the sliding component 42 and the positioning matching portion 411 on the positioning component 41 abut against each other. Specifically, when the user presses the sliding component 42 to extend the tip of the refill 2 outside the pen barrel 1 in the writing state, the positioning component 41 and the sliding component 42 cooperate with each other, and the positioning matching portion 411 and the positioning portion 40 abut against each other to limit the axial movement of the sliding component 42, thereby stably maintaining the extended state of the refill 2 and ensuring that the tip of the refill 2 will not retract due to the slightest external force during the user's writing process.

[0058] In the process of pressing the sliding component 42 to rotate the positioning component 41, the rotation drive part 46 of the sliding component 42 and the drive fitting part 412' of the positioning component 41 always abut against each other and will slide relative to each other. Specifically, in the process of pressing the sliding component 42, the rotation drive part 46 and the drive fitting part 412' abut against each other, and the sliding component 42 drives the pen core 2 to move toward the head of the pen barrel 1, and the pen core 2 will compress the spring 3. After the positioning part 40 and the positioning fitting part 411 are separated from each other, the rotation drive part 46 and the drive fitting part 412' abut against each other, and the drive fitting part 412' will also rotate relative to the rotation drive part 46, so as to drive the positioning component 41 to rotate. The axial force generated on the sliding component 42 when pressed can be smoothly converted into the force to drive the positioning component 41 to rotate, making the rotation of the positioning component 41 smoother.

[0059] In one embodiment, the positioning member 41 is a tubular structure, and the sliding member 42 is a rod-shaped structure; The positioning component 41 is sleeved on the outside of the sliding component 42 .

[0060] 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 body 1.

[0061] In one embodiment, the positioning fitting portion 411 and the driving fitting portion 412 ′ are provided on the inner wall of the positioning component 41 ; The positioning portion 40 and the rotation driving portion 46 are disposed on an outer wall of the sliding member 42 .

[0062] Specifically, the nesting gap between the positioning component 41 and the sliding component 42 is utilized to achieve the mutual cooperation between the positioning component 41 and the sliding component 42, making the overall structure more compact, which is not only conducive to controlling the overall size of the pen body 1 but also achieving a miniaturized design.

[0063] In one embodiment, a plurality of protruding structures 410 are provided on the inner wall of the positioning component 41, each protruding structure 410 includes a limiting rib 413' and two protrusions 414', and the protrusions 414' are sequentially surrounded by a first surface 401, a second surface 402, a third surface 403 and a fourth surface 404, the second surface 402 and the fourth surface 404 are arranged in back to back relation 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' is connected between 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 fitting portion 412', and the limiting rib 413' is the positioning fitting portion 411; The plurality of protruding structures 410 are distributed around the axis of the positioning component 41 , and a guide groove 415 ′ is formed between two adjacent protruding structures 410 ; The positioning portion 40 is a positioning rib provided on the sliding component 42 , and the rotation driving portion 46 is a driving rib provided on the sliding component 42 .

[0064] Specifically, regarding the state switching of the refill 2, when the pen is in the non-writing state, that is, when the tip of the refill 2 is retracted into the pen body 1, the positioning rib on the sliding component 42 is located in the guide groove 415' formed by the adjacent raised structure 410. The guide groove 415' effectively stores and limits the positioning rib, preventing it from dangling in the non-working state and ensuring the stability of the refill 2 in the retracted state.

[0065] When the user presses the sliding member 42, the driving rib moves toward the first surface 401 near the protrusion 414'. During this movement, after the positioning rib disengages from the guide groove 415', the driving rib abuts against the first surface 401. As the sliding member 42 continues to move, the driving rib slides relative to the first surface 401, causing the positioning member 41 to rotate within the pen body 1. Due to the inclined angle of the first surface 401, the driving rib applies a circumferential driving force to the positioning member 41 during the sliding process, causing the positioning member 41 to rotate. As the positioning member 41 rotates, the position of the guide groove 415' also changes accordingly. When the sliding member 42 is pressed to the maximum stroke, the driving rib abuts against the limiting rib 413'. After the user releases the pressure on the sliding member 42, the positioning rib abuts against the third surface 403 under the rebound force of the spring 3. Due to the inclined angle design of the third surface 403, the positioning rib cooperates with the third surface 403 to drive the positioning member 41 to continue rotating. Ultimately, under the action of the spring 3, the positioning rib abuts against the limiting rib 413'. At this time, the tip of the pen refill 2 is extended, and the pen enters the writing state. The close cooperation between the limiting rib 413' and the positioning rib stably locks this state.

[0066] When the sliding member 42 is pressed again, the driving rib moves toward the first surface 401 of the protrusion 414'. During this movement, after the positioning rib leaves the limiting rib 413' and disengages from the space between the two protrusions 414', the driving rib abuts the first surface 401 of the other protrusion 414'. As the sliding member 42 continues to move, the driving rib and the first surface 401 slide relative to each other, causing the positioning member 41 to rotate within the pen body 1. When the sliding member 42 is pressed to its maximum travel, the driving rib abuts the limiting rib 413'. When the user releases the pressure on the sliding member 42, the spring 3's rebound force causes the positioning rib to abut the third surface 403 of the other protrusion 414'. The positioning rib and the third surface 403 cooperate to drive the positioning member 41 to continue rotating. Eventually, under the action of the spring 3, the positioning rib slides into the guide groove 415'. At this point, the tip of the pen refill 2 retracts into the pen body 1.

[0067] In terms of force transmission, the driving ribs cooperate with the first surface 401, and the positioning ribs cooperate with the third surface 403 to achieve efficient force transmission. The inclined design of the first surface 401 and the third surface 403 cleverly converts the axial force generated by the user pressing the sliding component 42 into the circumferential force that drives the positioning component 41 to rotate.

[0068] In which, when the tip of the pen core 2 is extended to the outside of the pen body 1 and is in a writing state, the positioning ribs abut against the corresponding limiting ribs 413 ′.

[0069] When the tip of the pen core 2 is retracted to the outside of the pen barrel 1 , the positioning rib is located in the corresponding guide groove 415 ′.

[0070] When the tip of the pen core 2 is extended to the outside of the pen body 1 to the maximum stroke, the driving rib abuts against the corresponding limiting rib 413'.

[0071] 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 achieves stable switching between the two states of the refill 2, but also ensures efficient force transmission and improves the stability of the structure.

[0072] In one embodiment, the pen shaft 1 includes a rod body 101 and a plug 102. A step surface is provided on the inner wall of the tail of the rod body 101. The positioning component 41 is slidably provided on the step surface. The plug 102 is provided with a through-opening. The plug 102 is stuck at the tail of the rod body 101 and is located on the outside of the positioning component 41. The sliding component 42 passes through the through-opening.

[0073] Specifically, the separate design of the rod body 101 and the plug 102 facilitates the installation of the internal components of the pen body 1. During assembly, the refill 2, spring 3, sliding member 42, and positioning member 41 are first placed into the rod body 101 in sequence, and the plug 102 is then snapped onto the rear end of the rod body 101 to complete the overall assembly. This simplifies the assembly process and improves production efficiency. Furthermore, the secure and reliable connection between the plug 102 and the rod body 101 effectively prevents the plug 102 from falling off during use, ensuring the structural integrity of the pen body 1.

[0074] To facilitate user activation of the sliding member 42, a second actuator 44 is provided. This actuator passes through the positioning member 41 and the plug 102 and extends outside the pen body 1. This actuator 44 is located at the rear end of the pen body 1. Pressing this actuator drives the refill 2 to slide within the pen body 101. The second actuator 44 is a snap cap integrally formed on the sliding member 42. The positioning member 40 and the rotational drive member 46 are formed on this actuator.

[0075] In addition, the side wall of the rod body 101 can be provided with a slide groove 11, and the sliding member 42 is provided with a first pressing portion 43. The slide groove 11 extends along the sliding direction of the sliding member 42, and at least part of the first pressing portion 43 is provided outside the slide groove 11 and exposed outside the pen body 1.

[0076] The technical solution of the present invention has the following technical effects compared with the prior art: by providing a positioning matching portion and a driving matching portion on the positioning component, and correspondingly providing a positioning portion and a driving portion on the sliding component, during use, the positioning portion cooperates with the positioning matching portion to realize positioning of the pen tip of the pen refill after it extends out of the pen shaft to meet the requirements of normal writing, and the driving portion cooperates with the driving matching portion so that the sliding component can drive the positioning component to rotate in the pen shaft, and there is no need to provide complex structures such as guide ribs on the pen shaft. It is only necessary to rotatably set the positioning component on the pen shaft, and the sliding component is slidably set on the pen shaft. Through the cooperation of the positioning matching portion on the positioning component and the positioning portion on the sliding component, and the cooperation of the driving matching portion on the positioning component and the driving portion on the sliding component, the positioning and driving of the pen refill can be realized, which greatly simplifies the processing technology of the pen shaft and reduces the processing cost; the structure of the push assembly is simple, and the cooperation between the positioning component and the sliding component is simple and efficient. In the process of realizing the positioning and driving of the pen refill, the mutual interference between complex components is reduced, and the probability of jamming is reduced, thereby improving the reliability of the push pen and providing users with a smoother use experience.

[0077] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
