Description

Technical Field

[0001] This application relates to the field of stationery, and particularly to a refillable pen. Background Art

[0002] With the continuous development of the market, refillable pens have gradually gained favor among consumers due to their unique advantages. The design of this type of pen allows users to change the refill and thus the writing color with relatively simple operations without replacing the entire pen barrel, which greatly extends the service life of the pen and reduces waste at the same time.

[0003] Currently, most refillable pens on the market that can switch refills usually require disassembling the front and back parts of the pen barrel and then removing the refill from it. For example, the Chinese utility model patent with the patent number CN201120228601.X discloses "a quick-refilling multi-color click pen", which can remove the refill and the clicking member together by rotating the top plug and aligning the notch of the top plug with the center line of the chute of the pen body, and then replace the new refill and clicking member.

[0004] It can be understood that during the refill replacement process of such refillable pens that can switch refills, users not only need to place the lower part of the pen barrel, but also need to invert the upper part of the pen barrel to remove the original refill. The refill replacement process is too cumbersome, and the refill replacement method cannot be operated with one hand. Summary of the Utility Model

[0005] In view of this, the purpose of this application is to provide a refillable pen to simplify the refill replacement process. This application adopts the following technical solutions:

[0006] A refillable pen, which includes: a refill; a pressing body connected to the refill; a pen barrel with a guiding port provided at the rear side of the pen barrel for guiding the refill and the pressing body to be inserted into the pen barrel; a barrel sleeve that moves within a range between an initial position and a first position at the rear side of the pen barrel, is movably connected to but does not disengage from the pen barrel, and has a limiting port corresponding to the guiding port provided at the front side of the barrel sleeve; when the barrel sleeve moves to the initial position, the barrel sleeve is connected to the pen barrel, and the limiting port cooperates with the guiding port to limit the guiding port and lock the refill in the pen barrel; when the barrel sleeve moves to the first position, the limiting port is separated from the guiding port to unlock the refill for replacing the refill.

[0007] Furthermore, a chute is provided on the rear side surface of the pen barrel, and a slider corresponding to the chute is provided inside the barrel sleeve. The chute cooperates with the slider to enable the barrel sleeve to move within a range between the initial position and the first position at the rear side of the pen barrel.

[0008] Further, along the horizontal direction of the pen barrel, the chute includes a first end and a second end. The cross-sectional width of the first end is greater than that of the second end, which is used to cooperate with the slider to guide the rod sleeve to move within the range between the initial position and the first position at the rear side of the pen barrel.

[0009] Further, the chute includes a first chute and a second chute. The first chute and the second chute are arranged at intervals with the guiding opening near the rear surface of the pen barrel.

[0010] Further, when the rod sleeve moves to the initial position, the limiting opening and the guiding opening are closed to form a sliding track; when the pressing body moves from the tail end of the sliding track to the top end of the sliding track, the pressing body pushes the pen refill to protrude from the front end of the pen barrel, and the pressing body forms an abutment with the interior of the pen barrel to lock the pen refill in a state; when the pressing body moves from the top end of the sliding track to the tail end of the sliding track, the pressing body disengages from the interior of the pen barrel to unlock the pen refill, and the pen refill retracts into the pen barrel.

[0011] Further, the pressing body is assembled into the pen barrel from the guiding opening, and the surface width of the pressing body is greater than the width of the sliding track.

[0012] Further, the refillable pen also includes: a pen clip, which is embedded in the rear side of the rod sleeve and has a spiral structure corresponding to the rear side of the pen barrel for assembling and fixing with the pen barrel.

[0013] Further, the pen clip includes a clip cap and a clip body extending downward from the outer side of the top end of the clip cap. The connecting part between the clip cap and the clip body is embedded in the rear side of the rod sleeve.

[0014] Further, the interior of the pen barrel has a fixing hole. The refillable pen also includes: a tail plug, which is arranged at the rear end of the rod sleeve, passes through the rod sleeve, and is assembled in the fixing hole to close the pen barrel.

[0015] Further, the refillable pen is a multi-refill pen.

[0016] As can be seen from the above technical solutions, the advantages and positive effects of the refillable pen proposed in this application are as follows:

[0017] In this application, by moving the rod sleeve to the rear side of the pen barrel, it is possible to separate the limiting opening and the guiding opening without the rod sleeve completely detaching from the pen barrel, and to extract the pressing body or the pen refill in the pen barrel and replace them. This enables the user to experience different ways of pressing out the refill and replacing the refill. And compared with the current refillable pens, there is no need to remove other related components, such as the pen cap, etc., which can effectively reduce the refill replacement process and improve the user experience.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0057] To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the implementation manners of this application in detail with reference to the accompanying drawings.

[0058] Please refer to Figure 1 , the refillable pen provided by this application may include: a pen refill (not shown in the figure), the front half of the pen barrel, and an operation component 1 serving as the rear half of the pen barrel. The operation component 1 includes: a push body 2, a housing 3, a barrel sleeve 4, a pen clip 5, and a tail plug 6.

[0059] Among them, the front end of the push body 2 is connected to the pen refill. A guiding port 31 is provided at the rear side of the housing 3, and a limiting port 41 corresponding to the guiding port 31 is provided at the front side of the barrel sleeve 4. The guiding port 31 and the limiting port 41 are combined to form a window, so as to guide the push body 2 to slide therein, thereby driving the pen refill connected to the push body 2 to extend or retract from the front end of the front half of the pen barrel.

[0060] The pen clip 5 is embedded in the rear side of the barrel sleeve 4 and has a spiral structure corresponding to the rear side of the housing 3 for assembling and fixing with the housing 3.

[0061] The pen clip 5 includes a clip cap 51 and a clip body 52 extending downward from the outer side of the top end of the clip cap 51. The connecting portion between the clip cap 51 and the clip body 52 is embedded in the rear side of the barrel sleeve 4.

[0062] The tail plug 6 can be embedded in the opening of the pen clip 5 to close the pen clip 5.

[0063] Specifically, the tail plug 6 includes a plug cap 61 and a tail plug rod 62. The plug cap 61 is embedded inside the pen cap, and the tail plug rod 62 passes through the barrel sleeve 4 and is assembled in the fixing hole 33 for cooperating with the plug cap 61 to close the housing 3, thereby limiting the barrel sleeve 4 to move in two positions.

[0064] The barrel sleeve 4 moves within the range of a closed position (the barrel sleeve 4 moves to a forward position) and an open position (the barrel sleeve 4 moves to a rearward position) at the rear side of the housing 3, and is movably connected but does not detach from the housing 3.

[0065] When the barrel sleeve 4 moves to the closed position, the barrel sleeve 4 is connected to the housing 3, and the limiting port 41 cooperates with the guiding port 31 to limit the guiding port 31 and block the pen refill in the housing 3 so that it cannot be taken out from the housing 3; when the barrel sleeve 4 moves to the first position, the limiting port 41 is separated from the guiding port 31 to release the blockage of the pen refill, and the consumer can take out the push body 2 and the pen refill connected thereto from the limiting port 41 and insert a new pen refill or the push body, thereby realizing replacement.

[0066] Please refer to Figures 2 to 4 , the push body 2 is assembled into the housing 3 from the guiding port 31, and the surface width of the push body 2 is greater than the width of the guiding port.

[0067] It can be understood that when the user uses the refillable pen provided by the present application, the relatively wide pressing body 2 can facilitate the user to press, so that the refill is in the core-out state or the refill is retracted.

[0068] Furthermore, a filler 7 is arranged inside the housing 3 around the pressing body 2 for protecting the pressing body 2 and other components inside the housing 3.

[0069] The guiding port 31 includes a limiting structure 312 with different widths, which cooperates with the corresponding convex structure 21 of the pressing body 2 to enhance the limitation of the pressing body 2 and prevent the pressing body 2 from falling off from the housing 3 during use.

[0070] The maximum width of the convex structure 21 of the pressing body 2 is greater than that of the limiting structure 312 at the corresponding guiding port 31, so that the pressing body 2 moves along the axial direction of the housing 3, improving the stability of the pressing body 2 inside the housing 3.

[0071] Please refer to Figure 5 , a slider 42 is arranged inside the barrel sleeve 4.

[0072] Please refer to Figure 6 and Figure 7 , a sliding groove 32 is arranged on the rear side surface of the housing 3. The sliding groove 32 includes a first end 321 and a second end 322. The maximum cross-sectional width of the first end 321 is greater than that of the second end 322, which is used to cooperate with the slider 42 to enable the barrel sleeve 4 to move within the range of the initial position (closed position) and the first position (open position) at the rear side of the housing 3, avoiding the barrel sleeve 4 from detaching from the housing 3 during movement.

[0073] The barrel sleeve 4 can move within the range of the closed position and the open position at the rear side of the housing 3 through the cooperation of the slider 42 and the sliding groove 32.

[0074] The barrel sleeve 4 includes at least two sliding grooves 32, and each sliding groove 32 and the guiding port 31 are arranged at intervals near the rear side surface of the housing 3.

[0075] When the barrel sleeve 4 moves to the closed position, the barrel sleeve 4 is connected to the housing 3, and the limiting port 41 cooperates with the guiding port 31 to limit the guiding port 31 and lock the refill inside the housing 3; when the barrel sleeve 4 moves to the open position, the limiting port 41 is separated from the guiding port 31 to unlock the refill for replacing the refill.

[0076] Specifically, when the barrel sleeve 4 is in the initial position, the limiting port 41 and the guiding port 31 are closed to form a sliding track. When the pressing body 2 moves from the rear end of the sliding track to the front end of the sliding track, the pressing body 2 pushes the refill to protrude from the front half part of the pen barrel, and the pressing body 2 forms an abutment with the inside of the housing 3 to lock the refill.

[0077] Please refer to againFigure 6 When the rod sleeve 4 is in the first position, the sliding track is in an extended state, and the pressing body 2 can move from the front end of the sliding track to the middle end of the sliding track, so that the pressing body 2 and the refill connected to the pressing body 2 are disengaged from the window at the middle end of the sliding track of the shell.

[0078] It should be noted that, as Figure 1 shown, the refillable pen provided in this application can be a multi-refill pen, and at least two refills are provided in the refillable pen. Each refill is respectively connected to a corresponding pressing body 2, and by pressing the pressing body 2, the corresponding refill is in the core-out state.

[0079] In addition, the refillable pen can also be a single-refill pen, that is, the pen only has a single refill. Those skilled in the art can make corresponding settings for the refillable pen according to the specific application scenario.

[0080] It can be understood that the other internal structures of the multi-refill pen and the single-refill pen (such as the settings and cooperation methods of related components such as elastic members and rotating wheels) are well known to those skilled in the art and will not be elaborated here.

[0081] Furthermore, the assembly method of the refillable pen of this application can specifically be:

[0082] 1. Use the slider 42 of the rod sleeve 4 to engage with the chute 32 of the shell 3 to position it, and insert the rod sleeve 4 into the shell 3.

[0083] 2. Insert the plug cap 61 into the clip cap 51, and the connecting part between the clip cap 51 and the clip body 52 is embedded in the rear guide groove of the rod sleeve 4, and fix the clip cap 51 to the rear side of the pen clip 5 by means of threads.

[0084] 3. Insert the tail plug rod 62 into the fixing hole 33 of the shell 3.

[0085] The assembled operating components are as Figure 8 shown. It can be understood that the installation methods of the pressing body 2 and the refill have been elaborated in detail above and will not be elaborated here.

[0086] Exemplarily, please refer to Figure 9 , the front surface of the holding part 8 is provided with an anti-slip sleeve 81, the rear end of the holding part 8 is used to connect the shell 3, and through the mutual cooperation of the shell 3 and the holding part 8, the interior of the refillable pen is covered, and the front end of the shell 3 is provided with a pen tip 82.

[0087] It can be understood that when the front end of the pressing body 2 is connected to the refill 9, by pressing the pressing body 2, the pressing body 2 drives the refill 9 to move to the front of the pen tip 82 and protrude, and is in a locked state. When pressing the pressing body 2 corresponding to other refills 9, the refill 9 protruding from the front end can be retracted into the pen tip 82, and other refills 9 are pushed to protrude to the front of the pen tip 82.

[0088] It can be understood that the related structures not mentioned in the refillable writing instrument provided by the present application are well-known structural designs to those skilled in the art. Reference can be made to, for example, the patent document CN201120228601.X mentioned in the background art and similar prior arts, and no further elaboration will be provided here.
