Description

Technical Field

[0001] This invention relates to the field of stationery technology, and more particularly to a double-layered push-button pen. Background Technology

[0002] Based on their usage, pens can be categorized into fixed pens, rotary pens, push-button pens, and sliding pens. Fixed pens have a fixed lead, using a cap to allow the tip to be exposed or concealed. Rotary pens move the lead linearly by rotating a portion of the tip, allowing the tip to move in and out. Push-button pens move a spring by pressing a portion of the tip, allowing the tip to protrude. Sliding pens allow the lead to slide, causing the tip to protrude or retract. Push-button pens are particularly convenient, as the tip can be easily moved in and out by pressing a button located at the top of the barrel. In a push-button pen, pressing the button once protrudes the tip, making it writable; pressing it again retracts the tip into the barrel for storage and protection.

[0003] However, the current age range applicable to push-button mechanical pens is relatively large. Due to different pen-holding habits, not all users can easily press the mechanical pen with one hand, especially for younger children, the top-pressing method is relatively inconvenient. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a double-layer press pen. By setting a double-layer press component, the user can press and pop out / retract the pen tip on one side of the press pen, making the pressing method more convenient and versatile.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-layer press-type pen includes a pen shell, a pen core, a spring, a press-locking component, and a double-layer press component. The pen shell is vertically through-hole, the pen core is installed inside the pen shell and its tip can protrude from the bottom of the pen shell, the spring for rebounding the pen core is located inside the pen shell and its two ends respectively abut against the inside of the pen shell and the outer wall of the pen core; the pen shell has a vertically arranged first sliding groove on its top outer diameter, and a fixed platform is provided in the middle section of the pen shell.

[0007] The press-locking component includes a press rod and a rotating rod installed inside the pen casing. The press rod is located on the upper part of the pen casing, and the upper part of the press rod protrudes from the pen casing. The upper part of the pen refill abuts against the press rod. The rotating rod is sleeved on the press rod, and the bottom end of the rotating rod abuts against the fixed platform. The rotating rod and the press rod are connected to each other through a press-locking structure. The press rod is provided with an annular groove.

[0008] The double-layer pressing component includes a vertically arranged driving component and a horizontally arranged fixing rod. The fixing rod is slidably connected to the first sliding groove, with one end engaged in the annular groove and the other end fixedly connected to the driving component.

[0009] Preferably, the double-layer pressing component further includes a fixing end plug, which includes a plug body and a pen clip. The plug body is fixed and protrudes from the top of the pen shell. One end of the pen clip is integrally set on the top of the pen cap, and the other end is set towards the bottom of the pen shell. The pen clip is provided with a second sliding groove, and the fixing rod passes through the first sliding groove and also through the second sliding groove.

[0010] Preferably, the fixing rod is provided with a limiting block, and the outer side of the limiting block abuts against the inner side of the pen clip.

[0011] Preferably, there are two limiting blocks, which are respectively located on the left and right sides of the fixing rod.

[0012] Preferably, the stopper inside the pen casing is also provided with a third sliding groove, which is positioned opposite to the second sliding groove; when the fixing rod is fixed on the annular groove, it passes through the first sliding groove, the second sliding groove and the third sliding groove at the same time.

[0013] Preferably, the top of the pen shell is provided with a fixing groove, and the plug is provided with a locking block, which is engaged in the fixing groove.

[0014] Preferably, the outer diameter of the pressing rod is provided with a pressing protrusion and a limiting protrusion, the pressing protrusion is located in the middle of the pressing rod, and the limiting protrusion is located below the pressing protrusion; wherein, the bottom of the pressing protrusion is provided with a first inclined edge, and the top of the limiting protrusion is provided with a second inclined edge.

[0015] The inner wall of the rotating rod is provided with a protruding engagement module that cooperates with the pressing rod. The protruding engagement module includes an annular protrusion. The top of the annular protrusion is provided with several evenly distributed engagement protrusions. The top of the engagement protrusion is provided with a third inclined side that is directly opposite the first inclined side. The bottom of the annular protrusion is provided with several evenly distributed inclined grooves and several vertically arranged and evenly distributed limiting grooves.

[0016] By engaging the pressing protrusion with the mating protrusion and engaging the limiting protrusion with the inclined groove and the limiting groove, and with the help of the spring, the pressing rod will extend / retract the pen refill from the bottom of the pen case.

[0017] Preferably, the pen shell is fitted with a soft film sleeve.

[0018] Preferably, the driving component is a rod or a doll-like component.

[0019] In summary, the advantages of this invention are as follows:

[0020] This dual-layer press-button pen offers two pressing methods. One method involves directly pressing the top of the pressing rod protruding from the pen shell. When the pressing rod is under pressure, other components of the locking mechanism cause the pen refill to extend or retract from the bottom of the pen shell. The other method involves pressing down on the driving component, which, through the transmission of the fixed rod, moves the pressing rod downward, thereby causing the pen refill to extend or retract from the bottom of the pen shell. This driving component can be designed as a rod or a toy; when designed as a toy, it enhances the pen's aesthetics and playability. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] It should also be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, a double-layered push-button pen includes a pen shell 1, a pen refill 2, a spring 3, a push-button locking element 4, and a double-layered push-button element 5. Since the pen shell 1, pen refill 2, spring 3, and push-button locking element 4 are conventional components of push-button pens, their structures are described in a simple manner.

[0031] like Figures 1 to 3 As shown, the pen casing 1 is a hollow, vertically continuous structure with a threaded front cap at its bottom. The pen refill 2 is housed inside the pen casing 1 and secured by the front cap. The pen tip can protrude / retract from the pen casing 1 with the cooperation of a spring 3 and a pressing locking element 4. The two ends of the spring 3 abut against the inside of the pen casing 1 and the outer wall of the pen refill 2, respectively. A vertically oriented first groove 11 is provided on the top outer diameter of the pen casing 1, and a fixing platform is located in the middle section of the pen casing 1. (The functions of the first groove 11 and the fixing platform will be described later.)

[0032] like Figures 1 to 4 As shown, the press-locking component 4 includes a pressing rod 41 and a rotating rod 42 installed inside the pen casing 1. The pressing rod 41 is located on the upper part of the pen casing 1, and the upper part of the pressing rod 41 protrudes from the pen casing 1 (this protruding part is used for the user to press), while the upper part of the pen refill 2 abuts against the pressing rod 41. The rotating rod 42 is sleeved on the pressing rod 41, and the bottom end of the rotating rod 42 abuts against the fixed platform; the rotating rod 42 and the pressing rod 41 are interconnected by a press-locking structure.

[0033] Specifically, a pressing protrusion 411 and a limiting protrusion 412 are provided on the outer diameter of the pressing rod 41, with the pressing protrusion 411 located in the middle of the pressing rod 41 and the limiting protrusion 412 located below the pressing protrusion 411; wherein, a first inclined edge 413 is provided on the bottom of the pressing protrusion 411 and a second inclined edge 414 is provided on the top of the limiting protrusion 412.

[0034] The inner wall of the rotating rod 42 is provided with a protruding engagement module that cooperates with the pressing rod 41. The protruding engagement module includes an annular protrusion 421. The top of the annular protrusion 421 is provided with several evenly distributed engagement protrusions 422. The top of the engagement protrusions 422 is provided with a third inclined side 423 that is directly opposite to the first inclined side 413 (the two have the same inclination direction). The bottom of the annular protrusion 421 is provided with several evenly distributed inclined grooves 424 (the inclination direction of the inclined grooves 424 is the same as the inclination direction of the second inclined side 414) and several vertically arranged and evenly distributed limiting grooves 425.

[0035] By pressing the engagement of the protrusion 411 with the engagement protrusion 422 and the engagement of the limiting protrusion 412 with the inclined groove 424 and the limiting groove 425, and with the cooperation of the spring 3, the pressing rod 41 will extend / retract the pen lead 2 from the bottom of the pen shell 1.

[0036] like Figures 1 to 3 As shown, in order to achieve the double-layer pressing effect of the press pen, an annular groove 43 is provided on the upper outer diameter of the pressing rod 41. The aforementioned double-layer pressing component 5 includes a vertically arranged driving component 51 and a horizontally arranged fixing rod 52. The fixing rod 52 is slidably connected to the first sliding groove 11, and one end of it is engaged in the annular groove 43, while the other end is fixedly connected to the driving component 51.

[0037] By incorporating a double-layered pressing component 5, the design makes it easier for younger children to use the pen. Furthermore, given the young age of the users, the pen's playability and aesthetic appeal will make it even more appealing. Therefore, the aforementioned driving component 51 can be a rod or a toy-like component, allowing users to remove and replace it according to their preferences.

[0038] like Figures 1 to 3 As shown, a fixing plug 53 is also provided on the basis of the above-mentioned double-layer pressing member 5. The fixing plug 53 includes a plug body 54 and a pen clip 55. The plug body 54 is fixed to the top of the pen shell 1 and its part protrudes from the pen shell 1 (the plug body 54 can be protruded by the protruding part of the pressing rod 41). One end of the pen clip 55 is integrally set on the top of the pen cap, and the other end is set towards the bottom of the pen shell 1. Among them, a second sliding groove 56 is provided on the pen clip 55 (the second sliding groove 56 connects upward to the outside of the pen clip 55). When the fixing rod 52 passes through the first sliding groove 11, it also passes through the second sliding groove 56.

[0039] By adding the aforementioned fixing plug 53, the overall stability and strength of the double-layer pressing component 5 can be enhanced, making it less prone to damage.

[0040] like Figures 1 to 3As shown, since the fixing is achieved solely by inserting one end of the fixing rod 52 into the annular slot 43, the driving component 51 and the fixing rod 52 are prone to falling off. Therefore, a limiting block 57 is provided on the fixing rod 52, with the outer side of the limiting block 57 abutting against the inner side of the pen clip 55. To better ensure stability, two limiting blocks 57 are provided, one on the left and one on the right side of the fixing rod 52.

[0041] like Figures 1 to 3 As shown, the stopper 54 located inside the pen casing 1 is also provided with a third sliding groove 58, which is positioned opposite the second sliding groove 56; when the fixing rod 52 is fixed on the annular groove 43, it passes through the first sliding groove 11, the second sliding groove 56, and the third sliding groove 58. This structure ensures that the fixing rod 52 can be well fixed on the annular groove 43.

[0042] According to the double-layer pressing member 5 described above, when the driving member 51 is needed, simply slide the driving member 51 into the second slide groove 56 from above, then rotate the driving member 51 so that the outer side of the limiting block 57 can abut against the inner side of the pen clip 55, and finally insert the fixing rod 52 into the annular slot 43.

[0043] like Figures 1 to 3 As shown, the top of the pen shell 1 is provided with a fixing slot 13, and the plug body 54 is provided with a locking block 59, which is engaged in the fixing slot 13. When the locking block 59 is engaged in the fixing slot 13, the first sliding groove 11, the second sliding groove 56 and the third sliding groove 58 are exactly on the same plane, so that the fixing rod 52 can be quickly fixed on the annular locking groove 43.

[0044] like Figures 1 to 3 As shown, a soft film sleeve 14 is provided on the pen shell 1. The soft film sleeve 14 can enhance the comfort of the press pen and also prevent the user from developing calluses.
