Description
Technical Field
[0001] The utility model relates to the technical field of signature pens, in particular to a pen with a novel structure. Background Art
[0002] The ballpoint pen is a common writing tool. The core-out methods of the ballpoint pen usually include rotary type and pressing type, and the pressing type is the most common. When using a ballpoint pen with a pressing type core-out, the user pushes out the pen core by pressing the pressing part at the end of the pen, and pressing the pressing part at the end of the pen again will retract the pen core. The advantage of this design is that the operation is simple, the response is sensitive, and it is suitable for fast writing.
[0003] However, the pressing type core-out method will cause noise problems during pressing, and the pressing part located at the end of the pen is easy to be touched, thus resulting in accidental telescoping during carrying or use. Therefore, it is necessary to further improve the structure of the pen. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a pen with a novel structure that does not generate noise and is not prone to accidental telescoping of the pen core according to the current situation of the prior art.
[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows: A pen with a novel structure includes a pen shell for accommodating the pen core and a transmission member arranged in the pen shell and capable of sliding up and down. An outlet for the pen core is provided at the lower end of the pen shell. The transmission member can slide up and down to drive the pen core to retract or extend out of the outlet. The characteristic lies in that: it further includes a turntable assembly vertically arranged on the pen shell and capable of rotating around its own axis, and a blocking block is arranged on the turntable assembly; an upwardly open groove is provided at the upper end of the transmission member, and the blocking block can rotate with the turntable assembly and be stuck into the groove to make the transmission member slide downwards, or disengage from the groove to make the transmission member slide upwards. During the process of the blocking block being stuck into the groove, the blocking block pushes the transmission member downwards, and then the transmission member extends the pen core out of the outlet; during the process of the blocking block disengaging from the groove, the blocking block releases the suppression on the transmission member, and the spring sleeved on the pen core will retract the pen core into the outlet.
[0006] Preferably, the turntable assembly further includes a rotating shaft and a rotating disk, and the rotating shaft is movably penetrated through the center of the rotating disk; a first connection hole is opened on the shell wall of the pen shell, and the rotating shaft is fixedly connected in the first connection hole.
[0007] In order to increase the contact area between the user and the rotating disk and improve the user experience, a clearance groove (112) opening upward is provided on the top of the pen housing (1), and the first connecting hole (111) is provided near the top of the pen housing (1). The rotating disk (32) is accommodated in the clearance groove (112) and a portion of the edge of the rotating disk (32) is exposed at the upper end of the pen housing (1).
[0008] In order to facilitate the user to easily rotate the rotating disk and improve the user experience, the side of the rotating disk (32) is provided with the retaining block, and the end surface of the retaining block away from the center of the rotating disk (32) is an arc-shaped surface; the groove (211) is an arc-shaped groove with an arc-shaped inner wall. The outer end of the retaining block and the inner wall of the groove are both arc-shaped, which can reduce the external force required when the retaining block is stuck in or out of the groove; in other embodiments, the retaining block can also be provided on the outer edge of the rotating disk.
[0009] To enhance the aesthetics of the pen structure, the rotating disk includes a first and second rotating disk spaced parallel to each other. The rotating shaft extends through the centers of both the first and second rotating disks, and the retaining block is positioned within the gap between them. The transmission member includes an upwardly extending transmission plate, the top edge of which is recessed downward to form the groove. The retaining block is concealed between the first and second rotating disks, and the corresponding transmission member is also concealed between the first and second rotating disks, enhancing the aesthetics.
[0010] To enhance the user experience, the stop block includes a far stop and a near stop, which are spaced apart along the circumference of the first turntable. The distance between the outer end of the far stop and the center of the first turntable is greater than the distance between the outer end of the near stop and the center of the first turntable. Both the far stop and the near stop can be engaged or disengaged from the groove as the turntable assembly rotates. When the far stop engages the groove, the transmission member extends the refill out of the refill outlet. After the turntable rotates a certain angle, the far stop disengages from the groove, and the near stop engages. When the near stop engages the groove, the user can feel the transmission member rise to its highest point.
[0011] In order to improve the durability of the far stop and the near stop, the far stop and the near stop are formed into one piece, and the stop block is provided with a third connection hole for the shaft to pass through. In some embodiments, the stop block, the first rotating disk 321 and the second rotating disk 322 can be an integrally formed structure.
[0012] For ease of processing, the blocking block includes a first monomer and a second monomer symmetrically arranged with the radial direction of the first turntable as the axis of symmetry. The first monomer and the first turntable are an integral part, and the second monomer and the second turntable are an integral part. The first monomer and the second monomer form the blocking block, and the first turntable and the second turntable can be opened and closed to facilitate the processing of the first monomer and the second monomer.
[0013] To improve the consistency of rotation of the first monomer and the second monomer, a first positioning hole is provided on the first monomer with the depth direction perpendicular to the side surface of the first turntable, and the second turntable is provided with a first positioning post that can penetrate into the first positioning hole; similarly, a second positioning hole is provided on the second monomer with the depth direction perpendicular to the side surface of the second turntable, and the first turntable is provided with a second positioning post that can penetrate into the second positioning hole.
[0014] Preferably, a vertically extending positioning groove is provided on the outer side wall of the transmission member, and a positioning block that can be snapped into the positioning groove is provided inside the wall of the pen shell; a rack that can increase friction is provided on the outer edge of the turntable assembly.
[0015] Compared with the prior art, the advantages of the present utility model are as follows: a blocking block that can rotate with the turntable assembly is provided on the turntable assembly. As the turntable assembly rotates, the blocking block gradually approaches the transmission member and pushes the transmission member downward. Finally, the blocking block slides into the groove. During this process, the transmission member gradually moves downward, causing the pen tip to extend out of the tip outlet. At this time, the groove forms a limit on the blocking block to ensure that the pen tip does not retract during writing; on the contrary, when the blocking block disengages from the groove as the turntable assembly rotates, the blocking block gradually moves away from the transmission member, and the transmission member gradually moves upward, causing the pen tip to retract into the tip outlet; the process of controlling the telescopic movement of the pen tip does not generate noise, and the telescopic movement of the pen tip is realized by the rotation of the turntable assembly. Even if there is an accidental touch during carrying and use, the pen tip is not likely to have an accidental telescopic movement. Description of the Drawings

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 7 The figure shows a preferred embodiment of a pen with a novel structure of the present invention, which includes a pen case 1, a transmission member 2, a turntable assembly 3, and a stop block provided on the turntable assembly 3. The stop block can rotate with the turntable assembly 3, and the stop block interacts with the transmission member 2. As the turntable assembly 3 rotates, the transmission member 2 is driven by the stop block to slide upward or downward, thereby driving the pen core to retract or extend from the pen case 1.
[0025] Specifically, the pen case 1 includes an upper shell 11 and a lower shell 12 that are threadedly connected. The lower end of the lower shell 12 is provided with a core outlet 10 for the pen core. A pen core (not shown in the figure) and a spring (not shown in the figure) for preventing the pen core from extending out of the core outlet 10 are provided inside the pen case 1. A transmission member 2 that can slide up and down is provided inside the pen case 1 and above the pen core, and a turntable assembly 3 is provided above the transmission member 2; a makeshift groove 112 is provided at the top of the upper shell 11, which opens upward and passes through the shell wall of the upper shell 11. The makeshift groove 112 is used to accommodate the turntable assembly 3 and part of the outer edge of the turntable assembly 3 is exposed on the left and right sides and the upper side of the makeshift groove 112, so that the user can easily move the outer edge of the turntable assembly 3; a first connecting hole 111 is provided near the top of the upper shell 11, and the extension direction is perpendicular to the opening direction of the makeshift groove 112. The first connecting hole 111 is square, and the turntable assembly 3 is connected to the first connecting hole 111.
[0026] The transmission member 2 is provided with a transmission plate 21 extending upward. The top edge of the transmission plate 21 is recessed downward to form a groove 211 for interacting with the above-mentioned blocking block. The inner wall of the groove 211 is arc-shaped.
[0027] The turntable assembly 3 includes a rotating shaft 31, a first turntable 321 and a second turntable 322. The first turntable 321 and the second turntable 322 are parallel to each other and spaced apart in the vertical direction. The rotating shaft 31 is movably inserted through the centers of the first turntable 321 and the second turntable 322. The first turntable 321 and the second turntable 322 can rotate around the rotating shaft 31. A rack 300 for increasing friction is provided on the outer edges of the first turntable 321 and the second turntable 322. One end of the rotating shaft 31 is provided with a square rod 311, and the square rod 311 is accommodated in the above-mentioned square first connection hole 111, so that no rotation occurs between the rotating shaft 31 and the pen shell 1. In addition, a pen clip 5 is provided at the outer end of the square rod 311, and the pen clip 5 can hide the connection structure between the first connection hole 111 and the square rod 311.
[0028] The blocking block is arranged in the gap between the first turntable 321 and the second turntable 322, and a third connection hole 43 for the rotating shaft 31 to pass through is provided on the blocking block. As Figure 4 , 5 shown, the blocking block includes a far blocking portion 4a and a near blocking portion 4b which are integrally designed. The distance between the outer end of the far blocking portion 4a and the third connection hole 43 is greater than the distance between the outer end of the near blocking portion 4b and the third connection hole 43. The end faces of the far blocking portion 4a and the near blocking portion 4b away from the third connection hole 43 are both arc-shaped surfaces. The far blocking portion 4a and the near blocking portion 4b can rotate with the turntable assembly 3 and snap into or out of the groove 211. As Figure 4 shown, the far blocking portion 4a snaps into the groove 211. The two sides of the groove 211 limit the far blocking portion 4a in the groove 211, and there is a certain distance between the lowest point of the far blocking portion 4a and the lowest point of the groove 211. At this time, the transmission member 2 extends the pen refill out of the refill outlet 10. After the turntable 32 rotates a certain angle, the far blocking portion 4a disengages from the groove 211. As Figure 5 shown, the near blocking portion 4b snaps into the groove 211. The two sides of the groove 211 limit the near blocking portion 4b in the groove 211, and the end face of the near blocking portion 4b is completely attached to the groove wall of the groove 211. When the near blocking portion 4b snaps into the groove 211, the user can sense that the transmission member 2 rises to the highest position.
[0029] In this embodiment, the blocking block is processed in the form of a first monomer 41 and a second monomer 42, the first monomer 41 and the first turntable 321 are an integral part, the second monomer 42 and the second turntable 322 are an integral part, and the first monomer 41 and the second monomer 42 are symmetrically arranged with the radial direction of the first turntable 321 as the symmetry axis; in order to improve the consistency of the first monomer 41 and the second monomer 42 during rotation, a first positioning hole 411 is provided on the first monomer 41, and the depth direction is perpendicular to the side of the first turntable 321, and the second turntable 322 is provided with a first positioning column 3221 that can be inserted into the first positioning hole 411; similarly, a second positioning hole 421 is provided on the second monomer 42, and the depth direction is perpendicular to the side of the second turntable 322, and the first turntable 321 is provided with a second positioning column 3211 that can be inserted into the second positioning hole 421.
[0030] In addition, a vertically extending positioning groove 22 is provided on the outer side wall of the transmission member 2 , and a positioning block 113 that can be inserted into the positioning groove 22 is provided in the shell wall of the pen shell 1 .
[0031] The assembly process of the pen with the new structure in this embodiment is as follows: the first positioning column 3221 is inserted into the first positioning hole 411 and the second positioning column 3211 is inserted into the second positioning hole 421, so that the first turntable 321 and the second turntable 322 are relatively closed; then the closed first turntable 321 and the second turntable 322 are placed in the makeshift groove 112 on the top of the upper shell 11 at the same time, and the rotating shaft 31 is inserted into the first connecting hole 111 and the third connecting hole 43 in sequence until the square rod 311 at one end of the rotating shaft 31 is stuck in the first connecting hole 111; then, the positioning function of the positioning groove 22 and the positioning block 113 is utilized to install the transmission part 2 in the upper shell 11; then, the pen core and the spring are installed in the upper shell 11, and the upper shell 11 and the lower shell 12 are threadedly connected to complete the entire assembly process.
[0032] In this embodiment, the refill control process of the pen with the new structure is as follows: the user turns the rack 300 on the outer edge of the first turntable 321 and the second turntable 322 to rotate the stop block; when the far stop portion 4a is engaged in the groove 211, the far stop portion 4a pushes the transmission member 2 downward, and then the transmission member 2 extends the refill out of the refill outlet 10; continue to turn the rack 300, the far stop portion 4a is out of the groove, and then when the near stop portion 4b is engaged in the groove 211, the transmission member 2 moves upward under the action of the spring, and the refill retracts to the refill outlet.
