[0017] like Figure 1 、 Figure 12-14 As shown, in one embodiment of the present application, a spliced ​​writing stationery is provided, comprising a pen holder 1 and a pen core 2 , wherein the pen core 2 is arranged in the pen holder 1 .

[0018] In order to facilitate users to carry different pens and switch between them, the end of the pen barrel 1 away from the pen tip 21 of the pen core 2 is provided with an inserting portion 12; The plug-in portion 12 is configured so that the pen barrels 1 of the two writing instruments are plugged into each other from the side through the plug-in portion 12 so that the two writing instruments are connected together.

[0019] Specifically, a plug-in portion 12 is formed at the tail of the pen barrel 1. When two writing instruments need to be assembled, the tails of the two pen barrels 1 are brought close to each other and then plugged together from the side through the plug-in portion 12.

[0020] Since the pen body includes two rod bodies 10, a port for the pen tip 21 of the pen core 2 to extend out is formed at one end of the rod body 10, and an inserting portion 12 is provided at the other end of the rod body 10; wherein, when the inserting portions 12 of the two rod bodies 10 are inserted together, the inserting portion 12 is configured to limit the separation of the two rod bodies 10 along the length direction of the rod body 10.

[0021] In actual use, the user can plug the two rod bodies 10 together from the side wall direction of the rod bodies 10 through the plug-in parts 12. Moreover, after the two plug-in parts 12 are connected together, on the one hand, the two rod bodies 10 can be reliably connected together through the two plug-in parts 12, and on the other hand, the two plug-in parts 12 can effectively prevent the two rod bodies 10 from separating and falling off along their length direction because they are plugged in from the side, thereby improving the reliability of use.

[0022] In one embodiment, the plug-in portion 12 includes a slot 121 and an inserting strip 122 arranged side by side.

[0023] Specifically, the slot 121 and the insertion strip 122 are formed on the end surface of the rod body 10, and the slot 121 forms an insertion opening 123 on the side wall of the rod body; after the two rod bodies are inserted together, the insertion strip on one rod body is inserted into the corresponding slot through the insertion opening on the other rod body.

[0024] During assembly, the inserting strip 122 of one pen holder 1 is inserted into the slot 121 of another pen holder 1 to ensure that the two pen holders 1 are securely connected together.

[0025] In another embodiment, a limiting portion 13 is provided in the slot 121 and a limiting matching portion 14 is provided on the inserting strip 122; After the two rod bodies 10 are inserted together, the limiting portion 13 on one rod body 10 is connected to the limiting matching portion 14 on the other rod body 10 to limit the two rod bodies 10 on the connection surface formed by the two rod bodies 10.

[0026] Specifically, during use, after the two rod bodies 10 are inserted together through the plug-in portion 12 and assembled in place, the limiting portion 13 and the limiting matching portion 14 are connected together, and then the limiting portion 13 and the limiting matching portion 14 cooperate with each other to limit the position between the two plug-in portions 12. In this way, during use, the limiting portion 13 and the limiting matching portion 14 limit the relative sliding of the two plug-in portions 12 along the length direction of the slot 121, thereby reducing the possibility of the two rod bodies 10 separating laterally from each other, thereby improving reliability.

[0027] In certain embodiments, the limiting portion 13 and the limiting and engaging portion 14 may have various structural forms. For example, the limiting portion 13 may be a first protrusion formed in the slot 121, and the limiting and engaging portion 14 may be a first recessed portion formed on the insert 122. Alternatively, the limiting portion 13 may be a second recessed portion formed in the slot 121, and the limiting and engaging portion 14 may be a second protrusion formed on the insert 122.

[0028] In another embodiment, an extension portion 124 is provided on the edge of the inserting strip 122 , and the extension portion 124 covers the outside of the slot 121 .

[0029] Specifically, for the inserting strips 122 and the slots 121 formed on the end of the rod body 10 , at least two protruding inserting strips 122 arranged side by side may be formed on the end surface of the rod body 10 , and a slot 121 may be formed between two adjacent inserting strips 122 .

[0030] In order to prevent the inserting strip 122 from falling out of the slot 121 , an extension portion 124 is provided on the edge of the inserting strip 122 . The extension portion 124 on one rod 10 can cooperate with the extension portion 124 on the other rod 10 to form an overlapping area, thereby limiting the two rods 10 from falling out along the length direction.

[0031] Furthermore, a limiting rib is provided on the bottom surface of the slot 121, and the extension portion 124 partially blocks the limiting rib; a limiting notch is provided on the inserting strip 122, and the opening of the limiting notch is arranged at the edge of the extension portion 124, and the projection of the area formed by the limiting notch along the length direction of the pen barrel 1 is located in the slot 121, and the limiting notch is located on the outside of the limiting rib; the limiting rib forms the limiting portion 13, and the limiting notch forms the limiting fitting portion 14.

[0032] Specifically, since the rod body 10 is generally made of plastic and processed by mold injection molding, in the process of forming the insert 122, the slot 121, the limit portion 13 and the limit matching portion 14 at the end of the rod body 10, it is necessary to consider the demolding requirements during the mold processing process.

[0033] In particular, the restriction of the extension 124, which is additionally configured on the insert 122 to prevent it from falling out, increases the difficulty of forming the stopper 13 in the slot 121 and the stopper mating portion 14 on the insert 122. Therefore, by forming a stopper notch on the extension 124 to form the stopper mating portion 14, the difficulty of machining the stopper mating portion 14 on the insert 122 can be reduced. At the same time, a stopper rib is provided in the slot 121 to cooperate with the stopper notch on the other rod 10 to achieve a stopper position that meets the requirements of use.

[0034] In another embodiment, the outer surface of the inserting strip 122 is provided with a chamfered structure 15 at the edge of the limiting notch.

[0035] Specifically, the chamfered structure 15 can meet the requirement of smooth demolding of the limiting notch on the one hand, and on the other hand, the chamfered structure 15 can better fit together with the limiting rib.

[0036] In another embodiment, the limiting rib is in an arc-shaped structure, and the edge of the limiting notch is also in an arc-shaped structure; the center of the projection shape of the area formed by the limiting notch along the length direction of the pen shaft 1 coincides with the center of the limiting rib.

[0037] Specifically, after the two plug-in parts 12 are plugged together, the limiting ribs of one rod body 10 are stuck in the limiting notch of the other rod body 10, and the limiting part 13 and the limiting matching part 14 between the two plug-in parts 12 will form a circular limiting connection surface, so as to more effectively and stably limit the two plug-in parts 12 to prevent deviation, and can further automatically align the two rod bodies 10 so that the center lines of the two plug-in rod bodies 10 coincide, thereby improving the comfort of use.

[0038] like Figures 1-11 As shown, the present invention provides a writing stationery, comprising a pen holder 1 and a pen core 2, wherein the pen core 2 is arranged in the pen holder 1, and a pen tip 21 of the pen core 2 extends out of the pen holder 1; The writing stationery further includes a sealing assembly 3, which includes a sleeve 31 and a sealing member 32. An opening 311 is formed at one end of the sleeve 31. A reversible sealing component 321 is provided on the sealing member 32. The sealing member 32 is located in the sleeve 31 and is configured to open and close the opening 311. The sealing member 32 is arranged on the outside of the pen barrel 1 , and the sleeve 31 is sleeved on the outside of the pen barrel 1 and can slide on the pen barrel 1 ; the sleeve 31 is configured to slide on the pen barrel 1 to drive the sealing member 321 to flip to open and close the opening 311 .

[0039] Specifically, after the refill 2 is inserted into the pen holder 1, the nib 21 of the refill 2 is exposed outside the pen holder 1. To protect the nib 21, a sealing assembly 3 is provided on the outside of the pen holder 1. The sleeve 31 of the sealing assembly 3 fits over the outside of the pen holder 1, while the sealing member 32 is located within the sleeve 31 and also disposed on the outside of the pen holder 1.

[0040] When the sealing component 321 is flipped over to close the opening 311 , the tip 21 of the pen core 2 is located inside the opening 311 , and the tip 21 of the pen core 2 is located inside the sleeve 31 .

[0041] Specifically, when not in use, the sealing component 321 of the seal 32 blocks the opening 311 of the sleeve 31, thereby forming a relatively closed space between the sleeve 31, the sealing component 321 and the pen body 1, and the pen tip 21 of the pen core 2 is located in the relatively closed space for protection.

[0042] In addition, when the sealing component 321 is flipped over to open the opening 311 , the tip 21 of the pen core 2 is located outside the opening 311 , and the sleeve 31 is away from the tip 21 of the pen core 2 .

[0043] Specifically, when the user needs to use the pen, the sleeve 31 is pulled outside the pen barrel 1 to open it. The specific process is that the sleeve 31 slides outside the pen barrel 1 in a direction away from the pen tip 21. During the sliding process of the sleeve 31, the sealing component 321 is exposed from the opening 311. On the other hand, the exposed sealing component 321 flips open the opening 311 and finally allows the tip of the pen core 2 to extend from the opening 311.

[0044] By arranging a sealing assembly 3 on the outside of the pen barrel 1, the sleeve 31 is sleeved on the outside of the pen barrel 1 and can slide on the outside of the pen barrel 1. The sliding sleeve 31 can drive the sealing component 321 on the sealing member 32 to flip, thereby opening the opening 311 of the sleeve 31 to allow the pen tip 21 of the pen tip to extend out of the opening 311 for writing, or closing the opening 311 to protect the pen tip 21 of the pen tip; during use, when the opening 311 needs to be opened for use, the user pulls the sleeve 31 to make the sleeve 31 slide on the pen barrel 1, thereby driving the sealing component 321 to flip open the opening 311 to expose the pen tip 21 of the pen core 2. In this way, it is possible to avoid the pen tip 21 being exposed due to misoperation caused by pressing, thereby reducing misoperation and improving user experience and safety.

[0045] In one embodiment, the sealing member 32 includes a first connecting member 322, a second connecting member 323, and a flexible connecting member 324. The sealing member 321 is disposed between the first connecting member 322 and the second connecting member 323 via the flexible connecting member 324. The sealing member 321 can be flipped relative to the first connecting member 322 and the second connecting member 323. The sleeve 31 is provided with a pulling portion 312, and the pulling portion 312 is configured to pull the first connecting component 322 to slide together when the sleeve 31 slides toward the pen tip 21 away from the pen core 2, so that the sealing component 321 is exposed from the opening 311 and flips open the opening 311.

[0046] Specifically, to enable the sleeve 31 to slide away from the pen tip 21 and thereby drive the sealing member 321 to flip and open the opening 311, a pulling portion 312 is provided on the inner wall of the sleeve 31. During movement of the sleeve 31, the pulling portion 312 applies a pulling force to the first connecting member 322, enabling the first connecting member 322 to follow the movement of the sleeve 31 on the pen barrel 1. As the first connecting member 322 moves relative to the pen barrel 1, the first connecting member 322 moves relative to the second connecting member 323, and the flexible connecting member 324 causes the sealing member 321 to flip between the first connecting member 322 and the second connecting member 323 to open the opening 311.

[0047] A protruding pull-fit portion 3221 is provided on the outer surface of the first connecting member, and the pulling portion 312 will be pressed against the pull-fit portion 3221 , thereby causing the first connecting member to slide on the pen body 1 following the sleeve 31 .

[0048] In another embodiment, a pushing portion 313 is provided on the inner wall of the sleeve 31, and the pulling portion 312 is located between the pushing portion 313 and the opening 311; the pushing portion 313 is configured to push the first connecting component 322 to slide together when the sleeve 31 slides toward the pen tip 21 close to the pen core 2 so that the sealing component 321 flips over and retracts into the opening 311 to close the opening 311.

[0049] Specifically, after use, the user pushes the sleeve 31 in the reverse direction so that the sleeve 31 moves toward the pen tip 21. During the movement, the sleeve 31 pushes the first connecting member to move in the reverse direction through the pushing portion 313, thereby enabling the first connecting member to slide toward the pen tip 21. During the sliding process, the sealing component 321 flips and resets and finally blocks the opening 311 of the sleeve 31.

[0050] Likewise, a push-fitting portion 3222 may be further configured on the first connecting member, and the pushing portion 313 abuts against the push-fitting portion 3222 so that the first connecting member is pushed back to its original position.

[0051] In some embodiments, in order to ensure intermittent sliding of the first connecting member and the second connecting member during the reciprocating sliding of the sleeve 31, a first elastic claw 3223 may be provided on the first connecting member, a second elastic claw 3231 may be provided on the second connecting member, and a limiting portion 314 may also be provided in the sleeve 31.

[0052] Specifically, when the sealing component 321 is in a state of closing the opening 311 , the first elastic claw 3223 and the second elastic claw 3231 are staggered along the length direction of the pen barrel 1 , wherein the first elastic claw 3223 is close to the opening 311 and the second elastic claw 3231 is away from the opening 311 .

[0053] Thus, during the opening process, the sleeve 31 moves so that the staggered first and second elastic claws 3223, 3231 sequentially pass over the limiting portion 314 and move to one side of the limiting portion 314. During this process, the pulling portion 312 gradually approaches the pulling engagement portion 3221, the sealing member 32 remains substantially stationary, and the sealing component 321 is exposed from the opening 311.

[0054] As the sleeve 31 continues to move, the pulling portion 312 abuts against the pulling fitting portion 3221. At this time, the first connecting member will move with the sleeve 31, while the second connecting member will remain stationary because the second elastic claw 3231 is stuck on the limiting portion 314. In this way, the sealing component 321 can be flipped open.

[0055] In one embodiment, for the sleeve 31 , in order to facilitate the assembly of the seal 32 , the sleeve 31 includes a first cylinder 301 and a second cylinder 302 , and the first cylinder 301 and the second cylinder 302 are detachably connected together; The opening 311 is formed at the end of the first cylinder 301 . The pulling portion 312 is provided on the inner wall of the first cylinder 301 . The pushing portion 313 is provided on the inner wall of the second cylinder 302 .

[0056] Specifically, in order to facilitate assembly, the sleeve 31 adopts a split design, with a pulling portion 312 provided on the first cylinder 301 and a pushing portion 313 provided on the second cylinder 302 .

[0057] In one embodiment, in order to improve the sealing performance, a sealing ring 33 is further provided in the sleeve 31 . The sealing ring 33 is sleeved on the outside of the pen barrel 1 and is located between the pushing portion 313 and the sealing member 32 .

[0058] Specifically, the opening 311 of the sleeve 31 is blocked and covered by a sealing component 321 , and the sleeve 31 and the pen body 1 are airtightly sealed by a sealing ring 33 .

[0059] In one embodiment, the pen holder 1 is provided with a positioning portion 11, and the sleeve 31 is provided with a positioning matching portion 315 that matches the positioning portion 11; When the sealing component 321 is flipped over to open the opening 311 , the positioning portion 11 is connected to the positioning matching portion 315 to position the sleeve 31 at the position of the pen barrel 1 and keep it stationary.

[0060] Specifically, after pulling the sleeve 31 to expose the pen tip 21, the sleeve 31 still needs to be positioned to meet the user's normal writing requirements. When the sealing member 321 is flipped open to open the opening 311, the positioning portion 11 and the positioning matching portion 315 are connected together to position the sleeve 31. The positioning portion 11 and the positioning matching portion 315 can be represented by positioning ribs mating with positioning slots, or by two positioning ribs abutting against each other to achieve positioning.

[0061] In one embodiment, in order to maintain an effective closed state when the sealing member 321 closes the opening 311 without force, the writing instrument further includes a spring 4 disposed between the sleeve 31 and the pen body 1 , and configured to apply a spring force 4 to the sleeve 31 in a direction toward the pen tip 21 of the pen core 2 .

[0062] Specifically, when the opening 311 is closed by the sealing member 321, the spring 4 will constantly exert an elastic force on the sleeve 31 to prevent the sleeve 31 from sliding freely on the pen body 1. When the user needs to open the pen for use, they pull the sleeve 31 to overcome the elastic force of the spring 4. The spring 4 is located in the sleeve 31.

[0063] 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.
