[0045] 4. Spring. Detailed implementation manner

[0046] As Figures 1 - 12 shown, the present utility model provides a push-pull type writing stationery, including a pen barrel 1 and a refill 2, the refill 2 is arranged in the pen barrel 1, and the tip 21 of the refill 2 extends to the outside of the pen barrel 1;

[0047] The push-pull type writing stationery further includes a sealing assembly 3, the sealing assembly 3 includes a first sleeve 31, a second sleeve 34 and a seal 32, one end of the first sleeve 31 is formed with an opening 311, and a sliding groove 315 is arranged on the tube wall at the other end of the first sleeve 31, the inner wall of the second sleeve is provided with a slide block 341, and the slide block 341 is slidably arranged in the sliding groove 315;

[0048] The seal 32 is provided with a flippable sealing component 321, the seal 32 is located in the first sleeve 31, and the sealing component is configured to open and close the opening 311;

[0049] Wherein, the seal 32 is arranged outside the pen barrel 1, the first sleeve 31 is sleeved outside the pen barrel 1 and close to the tip 21, and the second sleeve 34 is sleeved outside the pen barrel 1 and away from the tip 21; the first sleeve 31 is slidably arranged on the pen barrel 1; the first sleeve 31 is configured to slide along the pen barrel 1 and drive the sealing component 321 to flip to open and close the opening 311.

[0050] Specifically, during the actual assembly process, after the refill 2 is loaded into the pen barrel 1, the tip 21 of the refill 2 is in a state of being exposed outside the pen barrel 1; then, the seal 32 is installed outside the pen barrel 1 and the first sleeve 31 is sleeved outside the seal 32, and the first sleeve 31 will be sleeved outside the pen barrel 1 at the same time; the second sleeve 34 is also sleeved on the pen barrel 1, and the first sleeve 31 and the second sleeve 34 are butted, so that the slide block 341 is loaded into the sliding groove 315 to realize the sliding assembly of the slide block 341 and the sliding groove 315.

[0051] During the reciprocating sliding of the first sleeve 31 along the rod body 1, the slider 341 cooperates with the chute 315, which can guide the smooth reciprocating sliding of the first sleeve 31 to improve the smoothness of use.

[0052] During use, by pushing and pulling the first sleeve 31, the first sleeve 31 reciprocates along the pen rod 1. When it is necessary to open the opening 311 to expose the pen tip 21 for writing, the first sleeve 31 can be pushed towards the second sleeve 34. During the sliding of the first sleeve 31 on the pen rod 1, the sealing component 321 on the seal 32 will be driven to flip to the outside of the opening 311 to open the opening 311. At the same time, the pen tip 21 will extend to the outside of the opening 311 of the first sleeve 31.

[0053] Conversely, when it is necessary to close the opening 311 so that the pen tip 21 retracts into the first sleeve 31 for protection. Then, the first sleeve 31 is pulled in the opposite direction away from the second sleeve 34. During the sliding of the first sleeve 31 on the pen rod 1, the sealing component 321 on the seal 32 will be driven to flip into the opening 311 to close the opening 311. At the same time, the pen tip 21 will retract into the first sleeve 31.

[0054] By arranging the sealing assembly 3 outside the pen rod 1, the first sleeve 31 is sleeved outside the pen rod 1 and can slide outside the pen rod 1. The sliding first sleeve 31 can drive the sealing component 321 on the seal 32 to flip, thereby realizing opening the opening 311 of the first sleeve 31 to meet the requirement that the pen tip 21 of the pen core 2 extends out of the opening 311 for writing use, or closing the opening 311 to protect the pen tip 21 of the pen core; during use, when it is necessary to open the opening 311 for use, the user pulls the first sleeve 31 to make the first sleeve 31 slide on the pen rod 1, thereby driving the sealing component 321 to flip to 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, and reduce misoperation to improve the user experience and safety.

[0055] Wherein, in the state where the sealing component 321 flips to close the opening 311, the pen tip 21 of the pen core 2 is located inside the opening 311, and the pen tip 21 of the pen core 2 is located inside the first sleeve 31.

[0056] Specifically, in the non-use state, the opening 311 of the first sleeve 31 is blocked by the sealing component 321 of the seal 32, so that a relatively closed space is formed between the first sleeve 31, the sealing component 321 and the second sleeve 34, and the pen tip 21 of the pen core 2 and the pen rod are located in this relatively closed space for protection.

[0057] That is, in the state where the sealing member 321 is flipped to close the opening 311, the pen barrel 1 and the pen core 2 are wrapped inside the sealing assembly.

[0058] In addition, in the state where the sealing member 321 is flipped to open the opening 311, the tip 21 of the pen core 2 is located outside the opening 311, and the first sleeve 31 is away from the tip 21 of the pen core 2.

[0059] Specifically, when the user needs to use it, it is opened by pulling the first sleeve 31 outside the pen barrel 1. The specific process is that the first sleeve 31 slides outside the pen barrel 1 in the direction away from the tip 21. During the sliding process of the first sleeve 31, on the one hand, the sealing member 321 will be exposed from the opening 311, and on the other hand, the exposed sealing member 321 will flip open the opening 311 and finally make the tip of the pen core 2 protrude from the opening 311.

[0060] In some embodiments, a clamping portion 316 is provided in the sliding groove, and the clamping portion 316 is arranged at the end of the sliding groove 315 close to the tip 21.

[0061] The clamping portion 316 is configured to be clamped and cooperate with the slider 341 to position the first sleeve 31 on the pen barrel 1 in the state where the sealing member 321 is flipped to open the opening 311.

[0062] Specifically, since the first sleeve 31 drives the sealing member 321 to open and close the opening 311 in a push-pull manner, when the user is writing, it is necessary to ensure that the first sleeve 31 remains in an unchanged state. For this reason, a clamping portion 316 is provided in the sliding groove 315. After the first sleeve 31 is pushed to expose the tip 21, the slider 341 slides relative to the sliding groove 315 to approach the clamping portion 316 and finally engages with the clamping portion 316 to limit the position of the first sleeve 31 on the pen barrel 1.

[0063] There can be various structures for the physical entity of the clamping portion 316. For example, the clamping portion 316 is a convex structure provided in the sliding groove 315 to meet the requirement of clamping the slider 341 to position the first sleeve 31.

[0064] In another embodiment, an insertion portion 317 extending outward is formed at the end of the first sleeve away from the tip, and the sliding groove 315 is provided on the insertion portion 317, and the insertion portion 317 is inserted into the second sleeve 34.

[0065] Specifically, in order to improve the connection reliability between the first sleeve 31 and the second sleeve 34 and ensure the smooth sliding of the first sleeve 31, a plug-in portion 317 is provided at the corresponding end of the first sleeve 31 to be inserted into the second sleeve 34. Thus, during the sliding process of the first sleeve 31 on the pen barrel 1, the sliding stability is improved by the plug-in portion 317 always being inserted into the second sleeve 34.

[0066] In some embodiments, a guiding portion 342 extending outward is provided at the end of the second sleeve 34 facing the pen tip 21.

[0067] A guiding slot 318 is provided on the outer wall of the first sleeve 31, and the guiding portion 342 is inserted into the guiding slot 318.

[0068] Specifically, during the sliding process of the first sleeve 31, in addition to the cooperation between the slider 341 and the sliding slot 315 for guiding, the sliding of the first sleeve 31 can be further guided by the cooperation between the guiding portion 342 and the guiding slot 318.

[0069] In another embodiment, in order to facilitate the installation of the slider 341 into the sliding slot 315, an installation guiding slot 319 is provided at the edge of the port of the plug-in portion.

[0070] Along the length direction of the sliding slot 315, the installation guiding slot 319 is arranged outside the sliding slot 315.

[0071] Specifically, during the assembly process, after the first sleeve 31 and the second sleeve 34 are both sleeved outside the pen barrel 1, the plug-in portion 317 of the first sleeve 31 is inserted into the second sleeve 34, and the slider 341 can be easily installed into the sliding slot 315 via the installation guiding slot 319 to achieve the purpose of convenient assembly.

[0072] In addition, for the first sleeve 31, both ends thereof are of an open structure. For the second sleeve 34, one end is of an open structure and the other end is of a closed structure to cooperate with the end of the pen barrel 1 away from the pen tip 21 to prevent the pen barrel 1 from disengaging from the second sleeve 34. For example, a plug 340 is provided at the end of the second sleeve 34 that needs to be closed, and the plug 340 can be clamped on the second sleeve 34.

[0073] In another embodiment of the present application, for the seal 32, in order to enable the sealing component 321 to flip under the drive of the first sleeve 31 to open and close the opening 311, the specific structure of the seal 32 is improved as follows.

[0074] The seal 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 through the flexible connecting member 324, and the sealing member 321 is flipable relative to the first connecting member 322 and the second connecting member 323;

[0075] The first sleeve 31 is provided with a pulling portion 312, and the pulling portion 312 is configured to pull the first connecting member 322 to slide together during the process of the first sleeve 31 sliding in a direction away from the tip 21 of the refill 2, so that the sealing member 321 is exposed from the opening 311 and the opening 311 is flipped open.

[0076] Specifically, in order to drive the sealing member 321 to flip open the opening 311 when the first sleeve 31 slides away from the tip 21, a pulling portion 312 is provided on the inner wall of the first sleeve 31. During the movement of the first sleeve 31, the pulling portion 312 will apply a pulling force to the first connecting member 322, so that the first connecting member 322 can move on the pen barrel 1 following the first sleeve 31. During the process of the first connecting member 322 moving relative to the pen barrel 1, a relative movement will be generated between the first connecting member 322 and the second connecting member 323, and the flexible connecting member 324 is used to cause the sealing member 321 to flip between the first connecting member 322 and the second connecting member 323 to open the opening 311.

[0077] Wherein, a protruding pulling cooperation portion 3221 is provided on the outer surface of the first connecting member 322, and the pulling portion 312 will abut against the pulling cooperation portion 3221, so that the first connecting member 322 slides on the pen barrel 1 following the first sleeve 31.

[0078] In another embodiment, the inner wall of the first sleeve 31 is provided with a pushing portion 313, 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 member 322 to slide together during the process of the first sleeve 31 sliding in a direction close to the tip 21 of the refill 2, so that the sealing member 321 flips and retracts into the opening 311 to close the opening 311.

[0079] Specifically, after the user finishes using, the first sleeve 31 is pushed in the reverse direction so that the first sleeve 31 moves towards the direction of the tip 21. During the movement of the first sleeve 31, the first connecting member is pushed to move in the reverse direction through the pushing portion 313, thereby realizing the sliding of the first connecting member towards the direction of the tip 21. During the sliding process, the sealing member 321 flips and resets and finally seals the opening 311 of the first sleeve 31.

[0080] Similarly, a pushing and fitting portion 3222 may also be arranged on the first connecting member. By the pushing portion 313 abutting against the pushing and fitting portion 3222, the first connecting member is pushed back to its original position.

[0081] In some embodiments, in order to satisfy the intermittent sliding of the first connecting member and the second connecting member during the reciprocating sliding of the first sleeve 31, a first elastic claw 3223 may be arranged on the first connecting member, a second elastic claw 3231 may be arranged on the second connecting member, and a limiting portion 314 is further arranged in the first sleeve 31.

[0082] Specifically, when the sealing member 321 is in the state of closing the opening 311, the first elastic claw 3223 and the second elastic claw 3231 are arranged in a staggered manner along the length direction of the pen barrel 1. Among them, the first elastic claw 3223 is close to the opening 311, and the second elastic claw 3231 is far from the opening 311.

[0083] In this way, during the opening process, the first sleeve 31 moves so that the staggered first elastic claw 3223 and the second elastic claw 3231 sequentially cross 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 and fitting portion 3221, the seal 32 remains basically stationary, and the sealing member 321 will be exposed from the opening 311.

[0084] As the first sleeve 31 continues to move, the pulling portion 312 abuts against the pulling and fitting portion 3221. At this time, the first connecting member will move along with the first 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 member 321 can be flipped open.

[0085] In one embodiment, in order to improve the sealing performance, a sealing ring 33 is further arranged in the first sleeve 31. The sealing ring 33 is sleeved outside the pen barrel 1 and is located between the pushing portion 313 and the seal 32.

[0086] Specifically, the opening 311 of the first sleeve 31 is blocked and covered by the sealing member 321, and the airtight treatment between the first sleeve 31 and the pen barrel 1 is performed through the sealing ring 33.

[0087] In one embodiment, in order to maintain an effective closed state in a non-force state when the sealing member 321 closes the opening 311, the push-pull type writing stationery further includes a spring 4. The spring 4 is arranged between the first sleeve 31 and the pen barrel 1, and the spring 4 is configured to apply a spring force 4 towards the tip 21 of the pen core 2 to the first sleeve 31.

[0088] Specifically, in the state where the opening 311 is closed by the sealing member 321, the spring 4 will always apply an elastic force to the first sleeve 31 to ensure that the first sleeve 31 does not slide on the pen barrel 1 randomly. When the user needs to open and use it, the first sleeve 31 is pulled to overcome the elastic force of the spring 4. Among them, the spring 4 is located in the first sleeve 31.

[0089] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
