Abstract
Description
Technical Field
[0001] The present application relates to the field of stationery products, and in particular to a writing tool. Background Art
[0002] At present, most gel pens on the market are push-type or pull-out type. Push-type gel pens generally have a pushable pen head. By pressing the button on the pen shaft, the pen head can be controlled to retract, making it convenient to write or draw. Pull-out gel pens, on the other hand, have a rotatable or removable pen head cap. When using, you need to open the pen head cap first, then align the pen tip with the position where you need to write, and press the pen head hard to start writing.
[0003] After using a pen, consumers may forget to press the retractor button or forget to put the cap back on. If the pen is dropped from a height, the pen tip will usually fall to the ground first, which may damage the pen tip and make it impossible to write, resulting in waste. If the pen is placed in a storage device with the retracted pen tip in place, the pen tip will come into contact with the inner wall of the storage device, causing ink to contaminate the inner wall of the storage device, which will also cause great inconvenience to consumers. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a writing tool to solve the above problems.
[0005] In order to solve the above technical problems, the present application adopts the following technical solutions: a writing tool, which includes: a pen shell extending in the axial direction and a pen core accommodated in the pen shell; a pressing body, which is supported in the pen shell so as to move forward and backward in the axial direction within the range of an initial position and a first position at the rear side of the pen shell, and the end of the pressing body is exposed outside the pen shell for axial pressing operation; a core ejection mechanism, the front end of the core ejection mechanism abuts against the pen core, and when the pressing body moves from the initial position to the first position, the pressing body pushes the core ejection mechanism to cause the pen core to protrude from the front end of the pen shell and is in a locked state state; the writing tool also includes a core shrinking mechanism, which selectively abuts against the core ejecting mechanism within the range of the second position and the third position. When the core shrinking mechanism moves to the third position, the core shrinking mechanism squeezes the core ejecting mechanism, and the core ejecting mechanism is unlocked; when the core ejecting mechanism is in the locked state, the pressing body moves to the first position again to unlock the core ejecting mechanism and retract the pen lead into the pen housing; or, when the writing tool is not in the normal use state, the core shrinking mechanism moves from the second position to the third position, unlocks the core ejecting mechanism and retracts the pen lead into the pen housing.
[0006] Furthermore, when the writing tool is not in normal use, the angle between the central axis of the writing tool and the plumb line is less than or equal to zero degrees.
[0007] Furthermore, the writing tool also includes: a sliding member, which is movably arranged inside the core output mechanism within the range of a fourth position and a fifth position. When the writing tool is in a normal use state, the sliding member is located at the fourth position. When the writing tool is not in a normal use state, the sliding member moves to the fifth position. When the sliding member is in the fifth position, the sliding member acts on the core shrinking mechanism to move it from the second position to the third position, thereby releasing the core output mechanism from a locked state.
[0008] Furthermore, when the writing tool is in a normal use state, the sliding member is located at the fourth position due to the influence of gravity.
[0009] Furthermore, the writing tool also includes: an attraction component, which can generate a force with the sliding component, and when the writing tool is in normal use, no force is generated between the sliding component and the attraction component; when the writing tool is not in normal use, the sliding component moves into the influence area of the attraction component, and a force is generated between the attraction component and the sliding component to guide the sliding component to move to the fifth position and be fixed at the fifth position.
[0010] Furthermore, a magnetic force is generated between the attraction component and the sliding member.
[0011] Furthermore, the core ejection mechanism includes: a core press, a middle section provided with a symmetrical inclined through groove, the opening size of the inclined through groove is smaller than the sliding part, and a symmetrical core press through groove is opened at the end away from the core, and the attraction component is assembled in the pen housing through the core press through groove, the lining through hole and the guide rail through hole.
[0012] Furthermore, the writing tool also includes: a guide rail, which is sleeved on the outside of the core output mechanism, and a plurality of hanging pieces are provided at one end of the guide rail away from the pressing body, and a through groove is provided between each hanging piece; a lining, which is assembled on the outside of the guide rail, and a groove with a structure corresponding to the hanging piece is provided on the inner surface close to the lining, and a convex surface is provided on the inner surface of the lining corresponding to the through groove, and the convex surface is used to guide the movement of the guide rail and the lining; when the pressing body moves from the initial position to the first position, the core output mechanism is abutted against the through groove, so that the core output mechanism is in a locked state; when the writing tool is not in normal use, the core shrinking mechanism moves to the third position, so that the core output mechanism disengages from the current through groove, slides along the hanging piece to another through groove, and releases the locked state of the core output mechanism.
[0013] Furthermore, at least one pair of symmetrical guide rail openings is provided on one side of the guide rail near the pressing body, and the lining is provided with a lining through-hole near the guide rail opening. The attraction component passes through the lining through-hole and the guide rail opening and is laterally assembled in the pen housing, and the attraction component moves axially in the lining through-hole and the guide rail opening.
[0014] Furthermore, at least one pair of axially symmetrical elastic cantilevers are provided near the lining through hole, and the core shrinking mechanism is close to the elastic cantilever. When the pressing body moves from the initial position to the first position, the elastic cantilever abuts against the concave surface formed by the lining through hole and the lining body, so that the core output mechanism is in a locked state; when the sliding member slides toward the rear side of the pen housing, the sliding member squeezes the core compression mechanism, so that the elastic cantilever extends outward along the horizontal plane direction, so that the elastic cantilever is separated from the concave surface formed by the lining through hole and the lining body, thereby releasing the locked state of the core output mechanism.
[0015] Furthermore, the core shrinking mechanism includes a ball, and the guide rail is also provided with at least one pair of symmetrical guide rail concave surfaces between the suspension plate and the guide rail opening. The guide rail concave surfaces are provided with axially symmetrical guide rail through holes, the guide rail through holes are aligned with the elastic cantilever, and the ball is assembled in the guide rail through holes.
[0016] Furthermore, the core ejection mechanism comprises: a rotating wheel having an opening, the bottom of the opening abutting against the top of the core, and a plurality of convex points on the outer surface close to the core, which are used to abut against the through groove.
[0017] Furthermore, the suspension piece is a sloped suspension piece, and the protrusion is an inclined protrusion. When the pressing body moves from the initial position to the first position, the rotating wheel advances along the sloped suspension piece through the inclined protrusion, forming abutment with the sloped suspension piece and the convex surface, and the pen core protrudes from the front end of the pen housing; when the writing tool is not in normal use, the lining slides to the rear side of the pen housing to release the abutment formed with the sloped suspension piece and the convex surface, and retract the pen core into the pen housing.
[0018] Furthermore, the pen shell also includes: a pen cover, which has a pen hole at the front end for the pen core to protrude from the front end; a pen shaft, which is connected to the end of the pen cover away from the pen hole and accommodates a pressing body, a core ejection mechanism and a core retraction mechanism; a boss is provided inside the pen cover, and the writing tool also includes an elastic member, which acts on the boss inside the pen cover and the front end of the pen core respectively.
[0019] It can be seen from the above technical solution that the advantages and positive effects of the writing tool proposed in this application are:
[0020] The present application takes into account that when users are not using writing tools, they usually place the writing tools on a horizontal surface such as a table, or turn the writing tools over to play with them. Therefore, by providing a core retracting mechanism, when the core ejecting mechanism is in a locked state, the core ejecting mechanism can be squeezed to release the locked state of the core ejecting mechanism, so that the refill of the tool can be automatically retracted into the pen housing, thereby improving the user experience of using the writing tool and preventing the ink of the refill from contaminating other objects.

According to the description, claims and drawings disclosed in this specification, the technical personnel in this field can easily understand the relevant purposes and advantages of the present application.
[0059] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0060] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product is usually placed when in use. 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, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.
[0061] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0062] The present application provides a writing tool, which includes: a pen housing extending in the axial direction and a pen core accommodated in the pen housing; a pressing body, which is supported in the pen housing so as to move forward and backward in the axial direction within the range of an initial position and a first position relative to the rear side of the pen housing, and the end of the pressing body is exposed outside the pen housing for axial pressing operation; a core-ejecting mechanism, the front end of the core-ejecting mechanism abuts against the pen core, and when the pressing body moves from the initial position to the first position, the pressing body pushes the core-ejecting mechanism to project the pen core from the front end of the pen housing and is in a locked state; the writing tool also includes a core-reducing mechanism, the core-reducing mechanism selectively abuts against the core-ejecting mechanism within the range of a second position and a third position, and when the core-reducing mechanism moves to the third position, the core-reducing mechanism squeezes the core-ejecting mechanism, and the core-ejecting mechanism is released from a locked state; when the core-ejecting mechanism is in a locked state, the pressing body moves again to the first position to release the core-ejecting mechanism from a locked state and retracts the pen core into the pen housing; or, when the writing tool is not in a normal use state, the core-reducing mechanism moves from the second position to the third position to release the core-ejecting mechanism from a locked state and retracts the pen core into the pen housing.
[0063] In one embodiment, when the writing tool is not in a normal use state, the angle between the central axis of the writing tool and the plumb line is less than or equal to zero degrees.
[0064] Exemplarily, the writing tool is not in normal use state when it is placed flat on a horizontal surface such as a table, so that the angle is zero degrees, or the end of the pen core is away from the horizontal plane, while the pressing body is close to the horizontal plane, and the writing tool is tilted, so that the angle is negative.
[0065] In one embodiment, the writing tool also includes: a sliding member, which is movably arranged inside the core output mechanism within the range of a fourth position and a fifth position. When the writing tool is in a normal use state, the sliding member is located at the fourth position. When the writing tool is not in a normal use state, the sliding member moves to the fifth position. When the sliding member is in the fifth position, the sliding member acts on the core shrinking mechanism to move it from the second position to the third position, thereby releasing the core output mechanism from a locked state.
[0066] In one embodiment, when the writing instrument is in a normal use state, the sliding member is located at the fourth position due to the influence of gravity.
[0067] It can be understood that when the writing tool is in a normal writing state, the sliding member is in the fourth position inside the core-out mechanism under the action of gravity. When the writing tool is in a non-writing state, for example, when it is placed flat on a horizontal surface such as a table, the sliding member moves from the fourth position to the fifth position under the action of the internal structure of the core-out mechanism, squeezing the core-reducing mechanism, so that the core-out mechanism is unlocked.
[0068] In one embodiment, the writing tool also includes: an attraction component, which can generate a force with the sliding member, and when the writing tool is in normal use, no force is generated between the sliding member and the attraction component; when the writing tool is not in normal use, the sliding member moves into the influence area of the attraction component, and a force is generated between the attraction component and the sliding member to guide the sliding member to move to the fifth position and be fixed at the fifth position.
[0069] In one embodiment, a magnetic force is generated between the attraction component and the sliding member.
[0070] Exemplarily, the attraction component and the sliding member may be objects with magnetic force. The attraction component is at the fifth position close to the inside of the core-outlet mechanism to strengthen the attraction to the sliding block, and quickly moves from the fourth position to the fifth position to release the locking state of the core-outlet mechanism.
[0071] In one embodiment, the attracting component may be a metal rod, and the slider may be a metal spherical object, such as a metal bead.
[0072] In another embodiment, the attracting component may be a magnetic rod, and the slider may be a magnetic spherical object, such as a magnetic bead.
[0073] It can be understood that the sliding block is a spherical object, which can facilitate the sliding resistance of the sliding block inside the core-out mechanism and facilitate the extrusion of the core-reducing mechanism.
[0074] It should be noted that there may not be any magnetic force generated between the attraction component and the sliding part, and the two only need to have a mutual attraction force. Those skilled in the art can select the corresponding attraction component and sliding part according to the specific usage scenario.
[0075] In one embodiment, the core ejection mechanism may include: a core press, a middle section provided with a symmetrical inclined through groove, the opening size of the inclined through groove is smaller than the sliding part, and a symmetrical core press through groove is opened at the end away from the core, and the attraction component is assembled in the pen housing through the core press through groove, the lining through hole and the guide rail through hole.
[0076] In one embodiment, the writing tool also includes: a guide rail, which is sleeved on the outside of the core output mechanism, and a plurality of hanging pieces are provided at one end of the guide rail away from the pressing body, and a through groove is provided between each hanging piece; a lining, which is assembled on the outside of the guide rail, and a groove with a structure corresponding to the hanging piece is provided on the inner surface close to the lining, and a convex surface is provided on the inner surface of the lining corresponding to the through groove, and the convex surface is used to guide the movement of the guide rail and the lining; when the pressing body moves from the initial position to the first position, the core output mechanism is abutted against the through groove, so that the core output mechanism is in a locked state; when the writing tool is not in normal use, the core shrinking mechanism moves to the third position, so that the core output mechanism disengages from the current through groove, slides along the hanging piece to another through groove, and releases the locked state of the core output mechanism.
[0077] In one embodiment, at least one pair of symmetrical guide rail openings are provided on one side of the guide rail close to the pressing body, and the lining is provided with a lining through-hole close to the guide rail opening. The attraction component passes through the lining through-hole and the guide rail opening and is laterally assembled in the pen housing, and the attraction component moves axially in the lining through-hole and the guide rail opening.
[0078] In one embodiment, at least one pair of axially symmetrical elastic cantilevers are provided near the lining through hole, and the core shrinking mechanism is close to the elastic cantilever. When the pressing body moves from the initial position to the first position, the elastic cantilever abuts against the concave surface formed by the lining through hole and the lining body, so that the core output mechanism is in a locked state; when the sliding member slides toward the rear side of the pen housing, the sliding member squeezes the core compression mechanism, so that the elastic cantilever extends outward along the horizontal plane direction, so that the elastic cantilever is separated from the concave surface formed by the lining through hole and the lining body, thereby releasing the locked state of the core output mechanism.
[0079] In one embodiment, the core shrinking mechanism includes a ball, and the guide rail is further provided with at least one pair of symmetrical guide rail concave surfaces between the suspension plate and the guide rail opening. The guide rail concave surfaces are provided with axially symmetrical guide rail through holes, the guide rail through holes are aligned with the elastic cantilever, and the ball is assembled in the guide rail through holes.
[0080] It is understandable that the ball is located inside the core-out mechanism to squeeze the elastic cantilever of the liner. When the ball is away from the elastic cantilever, the ball is in the second position, and when the small ball approaches the elastic cantilever and squeezes the elastic cantilever, the small ball is in the third position.
[0081] When the sliding member slides to the fifth position, the ball is squeezed, and the ball pushes the elastic cantilever outward, so that the elastic cantilever is freed from the abutment of the guide rail and the liner, and the locking state of the core-out mechanism is released.
[0082] Specifically, when the product is placed horizontally, the sliding part moves toward the ball position under the action of the core pressing inclined surface. When the sliding part is closer and closer to the ball, and under the action of the attraction between the attraction component and the sliding part, the sliding part pushes the ball to both sides. The ball thus pushes the cantilever on the liner apart, and the cantilever is separated from the concave surface of the two circular through holes on the guide rail, releasing the locking state of the core ejection mechanism.
[0083] In one embodiment, the core ejection mechanism includes: a rotating wheel having an opening, the bottom of the opening abuts against the top of the core, and the outer surface close to the core has a plurality of protrusions, which are used to abut against the through groove.
[0084] In one embodiment, the suspension piece is a sloped suspension piece, and the protrusion is an inclined protrusion. When the pressing body moves from the initial position to the first position, the rotating wheel advances along the sloped suspension piece through the inclined protrusion, forming abutment with the sloped suspension piece and the convex surface, and the pen core protrudes from the front end of the pen housing; when the writing tool is not in normal use, the lining slides to the rear side of the pen housing to release the abutment formed with the sloped suspension piece and the convex surface, and retract the pen core into the pen housing.
[0085] In one embodiment, the pen housing also includes: a pen cover, which has a pen hole at the front end for the pen core to protrude from the front end; a pen shaft, which is connected to the end of the pen cover away from the pen hole and accommodates a pressing body, a core ejection mechanism and a core retraction mechanism; a boss is provided inside the pen cover, and the writing tool also includes an elastic member, which acts on the boss inside the pen cover and the front end of the pen core respectively.
[0086] In one embodiment, the elastic member may include a telescopic spring, a first return spring, and a second return spring. The telescopic spring acts on the boss inside the pen cap and the convex surface at the front end of the pen core, respectively, the first return spring acts on the step inside the pen shaft and the end surface of the liner, respectively, to assist the liner to move along the axial direction, and the second return spring acts on the inside of the push body and the suction component, respectively, to maintain the length of the push body exposed when the pen core is ejected or retracted.
[0087] The entire embodiment will be fully described below.
[0088] like Figure 1 As shown, the writing tool 10 may include a pen cap 100, a pen barrel 200, a telescopic spring 300, a pen core 400, a first return spring 500, a sliding member 600, a ball 700, a lining 800, a guide rail 900, a pressing body 1000, a second return spring 1100, a pressing core 1200, a rotating wheel 1300, and an attraction component 1400, a total of 14 parts.
[0089] Please also refer to Figures 2 to 4 One end of the pen cover 100 is provided with a through hole for the pen tip of the pen core 400 to pass through, and the other end of the pen cover 100 is assembled on the pen holder 200. An inner step of the pen holder 200 is arranged inside the other end of the pen holder 200 to which the pen cover 100 is assembled, and one end of the return spring is against the inner step of the pen holder 200.
[0090] Please refer to Figures 5 to 8The guide rail 900 is assembled with one end of the pen holder 200 by means of a ring groove. The two symmetrical rectangular concave openings are formed in the front view below the ring groove of the guide rail 900. Two concave surfaces are designed at a 90° rotation position relative to the position below the two rectangular concave openings, and two circular through holes are formed on the concave surfaces. The tail end of the guide rail 900 is designed with three angled inclined hanging pieces, and there is a certain width of through groove between each of the two hanging pieces. The angles of the three hanging pieces and the three hanging piece through grooves are 120° for each.
[0091] Please refer to Figures 9 to 11 The attraction component 1400 is assembled in two rectangular concave openings on the guide rail 900. Since the diameter of the attraction component 1400 is smaller than that of the rectangular concave openings, the attraction component 1400 can move to a corresponding position along the axial direction of the guide rail 900 in the rectangular concave openings. Two balls 700 are assembled in the circular through holes on the guide rail 900.
[0092] The liner 800 has the appearance of a circular tube and is assembled on the outside of the guide rail 900. Two small cantilevers are designed at the circular through hole of the guide rail 900, and the cantilevers are in direct contact with the ball 700 in the circular through hole of the guide rail 900. Two circular through holes of the liner 800 are designed at the rectangular concave opening of the guide rail 900. The above-mentioned attraction component 1400 passes through the circular through hole of the liner 800 and the rectangular concave opening of the guide rail 900 when the liner 800 is jacketed over the liner 800. At this time, the liner 800 cannot move up and down relative to the guide rail 900 because the top of the cantilever is against the concave surface of the two circular through holes on the concave surface of the guide rail 900.
[0093] The other end of the liner 800 is designed with a slope structure with the same angle as the three hanging pieces of the guide rail 900. In addition, three small bosses are designed on the inner wall of the liner 800, where there is a certain width of through grooves between the two hanging pieces of the guide rail 900. The function of the small bosses is to accurately ensure that the liner 800 and the guide rail 900 slide in a relative straight line.
[0094] Please refer to Figures 12 to 15 , a ring groove is designed at one end of the pressing core 1200 away from the ratchet part to cooperate with the pressing body 1000. Two small rectangular through grooves are designed in the middle. The small rectangular through groove of the pressing core 1200 has a certain demoulding slope, and the width of the rectangular opening at the bottom of the slope is smaller than the diameter of the ball 700. Relative to the 90° direction of the small rectangular through groove of the pressing core 1200, two large rectangular grooves are designed and their positions are slightly higher than the small rectangular grooves. A step is designed above the ratchet part of the pressing core 1200, and the step is offset against the step at the root of the internal suspension piece of the guide rail 900.
[0095] For further information, please refer to Fig.16 and Fig.17The small rectangular through groove of the pressing core 1200 is used to assemble the attracting component 1400, and the large rectangular groove is used to assemble the ball 700. The inside of the large rectangular groove has a certain arc to prevent the ball 700 from passing through the large rectangular groove.
[0096] Please refer to Fig.18 The pressing core 1200 and the rotating wheel 1300 are assembled inside the guide rail 900. When assembled, the above-mentioned attraction component 1400 also passes through the large through slot on the pressing core 1200.
[0097] The sliding member (not shown) is assembled inside the pressing core 1200 from the top of the pressing core 1200. The bottom of the pressing core 1200 is designed with a closing to prevent the sliding member from falling out of the pressing core 1200. The interior of the pressing core 1200 is designed with a certain slope so that the sliding member can also move toward the ball 700 under the action of the slope when it is placed flat.
[0098] One end of the second return spring 1100 is against the inner wall of the push body 1000 and is assembled inside the push body 1000, and the other end is against the attraction component 1400. Its main function is to make the push body 1000 have the same exposed length regardless of whether it is in the core-out or core-retracted state.
[0099] The first return spring 500 is mentioned so that one end abuts against the inner step of the pen holder 200, and the other end abuts against the end surface of the liner 800. Its main function is to assist the liner 800 to move in the axial direction.
[0100] Please refer to Fig.19 and Fig. 20 When the pressing body 1000 is pressed, the pressing core 1200 is driven to move downward, and the end surface of the pressing core 1200 where the attracting component 1400 is assembled presses the attracting component 1400 to move downward, and the attracting component 1400 drives the lining 800 to move downward. At this time, the two cantilevers of the guide rail 900 are stuck in the concave surface of the two circular through holes of the lining 800. At this time, the convex points on the pressing core 1200 and the rotating wheel 1300 also move downward without rotating because they are matched with the width through grooves between the hanging pieces of the guide rail 900. When the convex points of the rotating wheel 1300 are separated from the large width through grooves of the hanging pieces of the guide rail 900, the rotating wheel 1300 is forced to rotate under the action of the ratchet teeth of the pressing core 1200. Since one end of the convex point of the rotating wheel 1300 is an inclined surface, and under the action of the retractable spring 300 of the refill 400, it will rotate a certain angle along the angle of the hanging piece of the guide rail 900 and slide into the angle formed by the hanging piece of the guide rail 900 and the angle boss of the liner 800. At this time, it is in the core-out state.
[0101] It can be understood that there are two ways to return to the core. The first way is to continue pressing the pressing body 1000, which is the same as the principle of an ordinary pressing pen. The present application focuses on providing a horizontal placement automatic core shrinking function. The principle of the return to the core method at this time is: when the product is placed horizontally, the sliding part moves toward the position of the small ball under the action of the inclined surface of the pressing core 1200. When the distance to the ball 700 is getting closer and closer, under the action of the mutual attraction between the attraction component 1400 and the sliding part, the sliding part pushes the ball 700 to both sides. The ball 700 therefore also pushes the cantilever on the liner 800 apart. At this time, the cantilever is separated from the concave surface of the two circular through holes on the guide rail 900, and the liner 800 moves upward under the action of the first reset spring 500 until the end face and the end face of the guide rail 900 are against each other. At this time, due to the upward movement of the liner 800, its internal inclined surface structure can no longer form an angle with the suspension piece of the guide rail 900. At this time, the rotating wheel 1300 will continue to slide along the inclined surface of the suspension piece of the guide rail 900 into the through groove between the suspension pieces. At this time, the pen core 400 completes the core shrinking action under the action of the telescopic spring 300.
