Description

Technical Field

[0001] This application relates to the technical field of writing instruments, and more specifically, to a push-button pen. Background Technology

[0002] A click pen allows for easy writing with a retractable lead by simply pressing a button with one hand, offering convenience and high flexibility. For example, a click pen disclosed in announcement number CN217944742U includes a pen body with a click assembly and a lead. The click assembly includes a pressing member with a pressing part that movably engages with a rotating member. The pressing part has an outer rotating tooth, and the rotating member has an inner rotating tooth, with the outer and inner rotating teeth movably meshing. However, a drawback is that the meshing connection between the pressing member and the rotating member produces a loud clicking sound, which can cause significant noise pollution in quiet indoor environments. Therefore, a low-noise, quiet click pen would better meet the needs of users in quiet indoor environments. Summary of the Invention

[0003] In view of the above-mentioned technical problems, the purpose of this application is to overcome the above-mentioned technical defects and provide a press-type jumping pen that can achieve low-noise, soft-press use.

[0004] Based on the above technical objectives, this application achieves its objectives through the following technical solutions:

[0005] A press-type jumping pen includes a pen tube, a pen refill, and a jumping mechanism. The bottom side of the pen refill is connected to the inside of the pen tube by a spring. The jumping mechanism is located on the top side of the pen refill and extends retractably from one end, connecting to the top side of the pen tube. The jumping mechanism includes:

[0006] The pressing block is retractably connected to the top side of the pen tube;

[0007] The card slot module is detachably positioned and connected to the inside of the pen tube. The card slot module has a first limiting part and a second limiting part along its side. The first limiting part and the second limiting part are connected to each other along the bottom side by a first linkage rail.

[0008] A drive push rod is telescopically connected between the slot modules. One end of the drive push rod is connected to the pressing block, and the other end forms a second linkage track. The second linkage track is telescopically connected to the first linkage track.

[0009] A linkage block is provided at one end of the drive push rod. The linkage block is rotatably connected between the first linkage rail and the second linkage rail, and is detachably latched to the first limiting part or the second limiting part along the side.

[0010] Through the above technical solution, the linkage block is driven by the alternating cooperation between the first linkage rail and the second linkage rail to achieve rotatable connection to the first limiting part or the second limiting part. The pen refill has a first position and a second position inside the pen tube. When it is in the first position, the linkage block is rotatably connected to the first limiting part, and the pen refill extends out of the pen tube. When it is in the second position, the linkage block is rotatably connected to the second limiting part, and the pen refill retracts into the pen tube.

[0011] Optionally, the pressing block and the card slot module are connected by an elastic reset structure.

[0012] Through the above technical solution, the elastic reset structure realizes the elastic extension and retraction reset of the pressing block and the driving push rod, thereby driving the linkage block to correspondingly achieve the clamping and positioning connection on the first or second limiting part of the card slot module.

[0013] Optionally, a positioning block is provided on the inner side of the pen tube, and the slot module is detachably positioned and connected to the positioning block.

[0014] Optionally, the positioning block and the slot module are connected along the side by an internal thread and an external thread structure.

[0015] Through the above technical solution, the card slot module is easy to assemble, position, and connect to the inside of the pen tube.

[0016] Optionally, the side of the drive push rod has an axially extending directional surface, and the top end face of the slot module has a corresponding guide opening, with the drive push rod connected to the guide opening via the directional surface.

[0017] Optionally, the drive push rod is formed in the shape of a polygonal right prism.

[0018] Through the above technical solution, the drive push rod is non-rotatably connected to the slot module along the central axis, so that the relative mating connection position between the first linkage rail and the second linkage rail is accurately positioned.

[0019] Optionally, the linkage block includes a shaft column and two locking sliders symmetrically arranged on the middle surface of the shaft column. The bottom side of the drive push rod is correspondingly provided with a shaft cylinder. The linkage block is rotatably positioned and connected between the shaft cylinders through the shaft column, and is detachably locked and connected between the first limiting part and the second limiting part through the locking sliders.

[0020] Optionally, the top side of the pen tube is also provided with a button cap, which is detachably positioned and connected to the top side of the pressing block.

[0021] Optionally, a positioning cavity is provided on the bottom side of the press cap, and the press cap is sleeved and connected to the pressing block through the positioning cavity. A first magnetic element is provided inside the positioning cavity, and a second magnetic element is correspondingly embedded on the top side of the pressing block. The first magnetic element and the second magnetic element are magnetically attracted to each other.

[0022] Optionally, the pen tube is integrally formed, with an open side formed along the top of the inner side of the pen tube and a pen tip through hole along the bottom. The jumping mechanism and the pen refill are connected to the inner side of the pen tube through the open side.

[0023] Through the above technical solution, this application can achieve the following beneficial effects:

[0024] (1) The jumping mechanism of this application avoids the clicking noise caused by the rotation and engagement of the traditional jumping pen press mechanism. In this application, the drive push rod and the card slot module are connected in an axial sliding telescopic manner to achieve the staggered connection between the first linkage track and the second linkage track. There will be no jamming between them, which will cause noise. The linkage block rotates relative to the staggered connection of the first linkage track and the second linkage track as the drive push rod extends and retracts, and is correspondingly connected to the first limit part and the second limit part of the card slot module, thereby achieving the low noise and light pressing effect of the jumping pen of this application.

[0025] (2) In this application, the jumping mechanism and the pen refill are modularly and detachably connected to the inside of the pen tube through the opening on the top side of the pen tube, which can achieve the integrity of the pen tube's appearance. This is different from most existing pen tubes, which usually adopt a two-section design (pen barrel-pen tip, upper pen barrel-lower pen barrel, etc.) for the convenience of pen refill replacement. In actual use, the pen refill and the spring are firstly sleeved together axially and inserted into the inside of the pen tube. Then, the jumping mechanism is screwed together with the positioning block through the slot module to achieve a positioning fit connection on the inside of the pen tube. It is also connected to the top of the pen refill through the linkage block. Finally, the button is magnetically fitted onto the pressing block to achieve a protruding connection on the top of the pen tube, thus completing the overall assembly of the jumping pen.
