Technical Field
[0001] This utility model belongs to the field of writing instrument technology, and in particular relates to a press-operated pen. Background Technology
[0002] As an indispensable writing tool, the convenience and practicality of pens have always been a focus of attention. Push-button pens, a type of pen, allow the refill to easily extend or retract into the pen holder by pressing the cap or sliding the clip, a design that greatly enhances writing flexibility and portability. However, in actual use, push-button pens have also revealed some problems. Especially when using a clip to attach the pen to a pocket or notebook, if the refill is forgotten to be retracted first, it can easily stain the pocket or notebook due to external pressure or friction, causing inconvenience. This problem is particularly prominent in fast-paced work and study environments, as users often need to frequently access and write with the pen in a short period, making it difficult to remember to retract the refill every time.
[0003] Therefore, there is an urgent need for a push-button pen that can automatically retract the lead. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a push-button pen that automatically triggers a retractable pen tip mechanism when the user clips the pen to their pocket or notebook, thereby preventing the pen tip from soiling the pocket or notebook and providing the user with a more convenient and practical writing experience.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pressable pen, comprising:
[0007] A pen holder, wherein the side of the pen holder is provided with a sliding groove and a positioning groove;
[0008] A pen refill assembly that can be movably installed inside the pen holder, the pen refill assembly being connected to a first elastic element;
[0009] A pen clip assembly is mounted on the outside of the pen holder. The pen clip assembly includes a pen clip and a connecting block rotatably connected to the pen clip. The end of the connecting block away from the pen clip is connected to the pen refill assembly via the sliding groove. A second elastic element is connected above the pen clip's rotation axis, and an elastic positioning element is connected below the pen clip's rotation axis. The elastic force of the second elastic element is greater than that of the elastic positioning element. When the pen clip assembly is slid, the pen refill assembly moves down and compresses the first elastic element, and the elastic positioning element falls into the positioning groove for limiting and locking. When the pen clip is rotated to compress the second elastic element, the elastic positioning element disengages from the positioning groove, and the first elastic element returns to its original position.
[0010] Furthermore, the pen clip has a first side groove on its inner side, and the connecting block is rotatably installed in the first side groove via a rotating shaft.
[0011] Furthermore, the connecting block is L-shaped and includes an elastic connecting end and a fixed connecting end. The second elastic element is disposed between the elastic connecting end and the bottom of the first side groove, and the fixed connecting end passes through the slide groove and is connected to the pen refill assembly.
[0012] Furthermore, the elastic connection end has an elastic element mounting groove on the side near the bottom of the first side groove, and the second elastic element is disposed between the bottom of the elastic element mounting groove and the bottom of the first side groove.
[0013] Furthermore, the inner side of the pen clip is provided with a second side groove corresponding to the lower part of the first side groove, and the elastic positioning member is installed in the second side groove.
[0014] Furthermore, the elastic positioning member includes a positioning member installed at the opening of the second side groove and a third elastic member installed between the positioning member and the bottom of the second side groove.
[0015] Furthermore, the pen holder has a limiting area on its side, and the sliding groove and the positioning groove are located in the limiting area. The pen clip can only slide up and down within the range defined by the limiting area.
[0016] Furthermore, the pen refill assembly includes a push rod and a pen refill that abuts against the push rod, and the connecting block is fixed to the push rod through the groove.
[0017] Furthermore, the connecting block is inserted vertically into the push rod, and the top end of the push rod is provided with a screw that is screwed onto the connecting block.
[0018] Furthermore, the pen holder is equipped with a rotating pen cap at the top.
[0019] The beneficial effects of this utility model are:
[0020] This invention utilizes a sliding groove and a positioning groove on the side of the pen holder to achieve the sliding and positioning locking functions of the pen clip assembly. This allows users to control the extension and retraction of the pen refill assembly by sliding the clip, while the positioning groove ensures the pen refill remains stable and does not slide when needed. When the clip is attached to a pocket or notebook, it rotates, releasing the positioning lock and automatically retracting the pen refill assembly. An elastic element mounting groove at the elastic connection end of the connecting block ensures the stability of the second elastic element. A third elastic element and a positioning element allow for flexible pop-up and reset of the positioning element. This invention automatically triggers the pen refill retraction mechanism when the pen clip is attached to a pocket or notebook, preventing the pen refill from soiling the pocket or notebook and providing a more convenient and practical writing experience.

[0032] See appendix Figure 1 To be continued Figure 6 The illustration shows a specific embodiment of the press-operated pen provided by this utility model.
[0033] See appendix Figure 1 and attached Figure 2 Pressing the pen includes:
[0034] Pen holder 1, with a sliding groove 110 and a positioning groove 120 on the side;
[0035] The pen refill assembly 2 is movable up and down inside the pen holder 1, and the pen refill assembly 2 is connected to the first elastic element 3;
[0036] The pen clip assembly 4 is installed on the outside of the pen holder 1. The pen clip assembly 4 includes a pen clip 410 and a connecting block 420 rotatably connected to the pen clip 410. The end of the connecting block 420 away from the pen clip 410 is connected to the pen refill assembly 2 through a slide groove 110. The pen clip 410 is connected to a second elastic member 440 above its rotation axis 430 and to an elastic positioning member 450 below its rotation axis 430. The elastic force of the second elastic member 440 is greater than that of the elastic positioning member 450. When the pen clip assembly 4 is slid, the pen refill assembly 2 moves down and compresses the first elastic member 3, and the elastic positioning member 450 falls into the positioning groove 120 for limiting and locking. When the pen clip 410 is rotated to compress the second elastic member 440, the elastic positioning member 450 disengages from the positioning groove 120, and the first elastic member 3 returns to its original position.
[0037] See appendix Figure 3 and attached Figure 6 In the above embodiment, the pen clip 410 can rotate slightly relative to the connecting block 420. The lower end of the pen clip 410 cooperates with the outer side of the pen holder 1 to achieve the purpose of clamping it into a pocket or notebook. When using the pen, the top of the pen clip 410 is pressed from top to bottom, causing the pen clip 410 to slide relative to the pen holder 1. The connecting block 420 connected to the pen clip 410 slides downward in the slide groove 110 at the same time. At the same time, the pen refill assembly 2 inside the pen holder 1 also slides downward to extend the pen tip out of the pen holder 1. During this process, the first elastic member 3 inside the pen holder 1 is compressed. The positioning groove 120 is located below the slide groove 110. When the pen clip 410 slides to the point where the elastic positioning member 450 corresponds to the positioning groove 120, the elastic positioning member 450 pops out and falls into the positioning groove 120. At this time, the pressing force is released, and the elastic positioning member 450 and the positioning groove 120 cooperate to achieve a locking effect, preventing the first elastic member 3 from rebounding, thereby fixing the pen tip of the pen refill assembly 2 in the extended state. When the pen clip 410 is clipped to a pocket or notebook, it rotates, causing the elastic positioning member 450 to disengage from the positioning groove 120 and release the locking state. At this time, under the elastic force of the first elastic member 3, the pen refill assembly 2 returns to its original position, thus achieving the purpose of automatically retracting the pen refill when the pen clip 410 is clipped to a pocket or notebook. In this embodiment, the elastic force of the second elastic member 440 is greater than that of the elastic positioning member 450, ensuring that under the elastic force of the second elastic member 440, the clamping end of the pen clip 410 always tends to be close to the side of the pen holder 1, ensuring the clamping effect. In this embodiment, both the first elastic member 3 and the second elastic member 440 are springs.
[0038] See appendix Figure 2In the above embodiment, the pen clip 410 has a first side groove 411 on its inner side, and the connecting block 420 is rotatably mounted in the first side groove 411 via a rotating shaft 430. In the embodiment, there is a space between the connecting block 420 mounted in the first side groove 411 and the bottom of the first side groove 411 to ensure that the pen clip 410 can rotate relative to the connecting block 420.
[0039] See appendix Figure 4 In the above embodiment, the connecting block 420 is L-shaped, including an elastic connecting end 421 and a fixed connecting end 422. The second elastic member 440 is disposed between the elastic connecting end 421 and the bottom of the first side groove 411. The fixed connecting end 422 passes through the slide groove 110 and connects to the pen refill assembly 2. In the embodiment, the corner position of the L-shaped connecting block 420 is installed in the first side groove 411 of the pen clip 410 via a rotating shaft 430, wherein the elastic connecting end 421 is located outside the pen barrel 1, and the fixed connecting end 422 is connected to the inside of the pen barrel 1.
[0040] See appendix Figure 4 In the above embodiment, the elastic connecting end 421 has an elastic element mounting groove 4211 on the side near the bottom of the first side groove 411, and the second elastic element 440 is disposed between the bottom of the elastic element mounting groove 4211 and the bottom of the first side groove 411. In this embodiment, a space for mounting the second elastic element 440 is formed between the elastic element mounting groove 4211 and the first side groove 411, which effectively avoids misalignment of the second elastic element 440 during the sliding or pressing of the pen clip 410, and improves the structural stability of the second elastic element 440.
[0041] See appendix Figure 3 In the above embodiment, a second side groove 412 is provided on the inner side of the pen clip 410 below the first side groove 411, and an elastic positioning member 450 is installed in the second side groove 412. The elastic positioning member 450 includes a positioning member 451 installed at the opening of the second side groove 412 and a third elastic member 452 installed between the positioning member 451 and the bottom of the groove of the second side groove 412. In the embodiment, the elastic force of the second elastic member 440 is greater than the elastic force of the third elastic member 452. Therefore, when the pen refill assembly 2 is in the retracted state, the groove opening of the second side groove 412 fits against the side of the pen holder 1 and presses the positioning member 451 into the second side groove 412, avoiding the situation where the third elastic member 452 pops out the positioning member 451, causing the clamping end of the pen clip 410 to tilt up, thus effectively ensuring the clamping effect of the clamping end of the pen clip 410.
[0042] See appendix Figure 2In the above embodiment, a limiting area 130 is provided on the side of the pen holder 1. The sliding groove 110 and the positioning groove 120 are located in the limiting area 130, and the pen clip 410 can only slide up and down within the range defined by the limiting area 130. In the embodiment, the first side groove 411 and the second side groove 412 of the pen clip 410 correspond to the limiting area 130 of the pen holder 1, so that the outer walls of the first side groove 411 and the second side groove 412 will not cross the boundary under the restriction of the limiting area 130, ensuring the stability of the pen clip 410 during the sliding process and avoiding shaking or misalignment.
[0043] See appendix Figure 5 In the above embodiment, the pen refill assembly 2 includes a push rod 210 and a pen refill 220 abutting against the push rod 210. A connecting block 420 passes through a slide groove 110 and is fixed to the push rod 210. The connecting block 420 is vertically inserted into the push rod 210, and a screw 230 is provided at the top of the push rod 210 to be screwed and fixed to the connecting block 420. In this embodiment, the connecting block 420 and the push rod 210 are fixed with screws 230 to ensure structural stability. Furthermore, in this embodiment, the pen holder 1 has a split structure, and the pen holder 1 can be separated by screwing from the middle position, which facilitates the replacement of the pen refill 220.
[0044] See appendix Figure 1 In the above embodiment, the top of the pen holder 1 is provided with a rotating pen cap 5. In this embodiment, a ball bearing is provided inside the rotating pen cap 5, allowing the user to rotate and play with the pen cap 5 for stress relief and entertainment.
[0045] In summary, this embodiment provides a press-to-open pen. A sliding groove 110 and a positioning groove 120 are provided on the side of the pen holder 1 to achieve the sliding and positioning locking functions of the pen clip assembly 4. This allows the user to control the extension and retraction of the pen refill assembly 2 by sliding the pen clip 410, and the positioning groove 120 ensures that the pen refill 220 remains stable and does not slide when needed. When the pen clip 410 is clipped to a pocket or notebook, the pen clip 410 rotates to release the positioning lock, achieving automatic retraction of the pen refill assembly 2. An elastic element mounting groove 4211 is provided at the elastic connection end 421 of the connecting block 420 to ensure the stability of the second elastic element 440. A third elastic element 452 and a positioning element 451 are provided to allow the positioning element 451 to flexibly pop out and reset. This embodiment can automatically trigger the pen refill retraction mechanism when the user clips the pen clip to a pocket or notebook, thereby preventing the pen refill from soiling the pocket or notebook and providing the user with a more convenient and practical writing experience.
[0046] The embodiments described above are merely one of the preferred embodiments of this utility model.
