Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the nouns of locality be included in term such as " tops, bottom, inside and outside " only represents the orientation of this term under normal service condition, or being commonly called as of understanding for those skilled in the art, and should not be considered as the restriction to this term.
See Fig. 1, the utility model provides a kind of Multifunction pen cap, the pen cap comprise set gradually from top to bottom a tail 1, tubular a body 2 and nib 3, tail 1 is provided with adjusting device, by device for regulating rotary can make adjusting device along the axial direction of a tail 1 move with against or away from the afterbody of the pen core be placed in a body 2.
Pass through technique scheme, a tail 1, a body 2 and nib 3 are connected in turn from top to bottom, by the adjusting device on pen with rotary tail 1, its axial direction along a tail 1 is moved, like this when the pen core more renewed, whether the length no matter being placed in pen core in a body 2 is applicable to, adjusting device all tightly can be resisted against the afterbody of new pen core, its head can be stretched out from written 3, be compensate for the deficiency of new pen core length by adjusting device, the package assembly between new pen core and the pen cap is compact stable be suitable for user and write.
In present embodiment, in order to simplify the structure of above-mentioned adjusting device, consider from the angle being convenient to user's operation, preferably, adjusting device comprises rotates push rod 4 and is set in the rotational sleeve 5 rotating push rod 4 outside; Wherein, a tail 1 forms a cylindrical cavity, and rotational sleeve 5 is placed in cavity; The sidewall sections of tail 1 is wrapped in the outside of rotational sleeve 5 and rotational sleeve 5 can in the cavities along self axial rotation; The outer wall rotating push rod 4 is provided with external screw thread 6, and the inwall of rotational sleeve 5 is provided with the internal thread 7 matched with external screw thread 6.Like this, due to rotational sleeve 5 rotation in the cavities, the internal thread 7 that its inwall is provided with interacts with the external screw thread 6 rotated on push rod 4 outer wall, the power of user being rotated rotational sleeve 5 passes to rotates push rod 4, make to rotate push rod 4 to eject in rotational sleeve 5 until be tightly resisted against the afterbody of the pen core of the new replacing be placed in a body 2, the new pen core of different length all can be used in combination with this Multifunction pen cap well.
In the process of above-mentioned rotation rotational sleeve 5, to overexert to prevent rotation or firmly the uneven rotational sleeve 5 that causes misplaces, rotary resistance is caused to increase, have impact on normal use, as shown in Figure 2, the top of preferred rotational sleeve 5 and bottom be part outwardly formation circular orientation projection 8 respectively, and the top of cavity and bottom part cave inward the circular orientation groove 9 being formed and match with circular orientation projection 8.
In addition, eject until be tightly resisted against this process of afterbody of the pen core of the new replacing be placed in a body 2 in rotational sleeve 5 at rotation push rod 4, excessively come off from rotational sleeve 5 in order to avoid rotation push rod 4 ejects, destroy the syndeton of whole adjusting device, preferably, form a container cavity in rotational sleeve 5, rotate push rod 4 and be located in container cavity; Container cavity is divided into two sections, and the inwall being positioned at the rotational sleeve 5 of hypomere is provided with the internal thread 7 matched with external screw thread 6; The inwall being positioned at the rotational sleeve 5 of epimere caves inward and forms the sliding cavity 10 of annular, and the top sidewall of rotation push rod 4 is outwards formed with annular stop circle 11 and Sealing shield ring 11 can be resisted against on the bottom face of sliding cavity 10.
In present embodiment, can eject longer distance to adapt to the wider length difference of new pen core to make to rotate push rod 4 in rotational sleeve 5, the length of preferred epimere and the length of hypomere are than being 1:1-3:1.
Because the bottom of rotating push rod 4 can repeatedly contact with pen core tail end when changing pen core, in order to increase contact area therebetween, preventing the two contact position to be subjected to displacement causes connection to come off, preferably, the bottom of rotating push rod 4 is provided with columniform extruding cushion block 12, the diameter of extruding cushion block 12 is greater than the diameter of rotation push rod 4, and extrudes cushion block 12 for rubber cushion blocks.
In the process using this Multifunction pen cap, conveniently dismounting is cleaned or maintenance, and the top of preferred body 2 is threaded connection and is removably connected with the bottom of a tail 1, and the bottom of a body 2 is threaded connection and is removably connected with the top of nib 3.
Be set with short pencil to use this Multifunction pen cap to write, the bottom of preferred tail 1 can be threaded connection and removably be connected with the top of nib 3.Because the length of pencil is shorter, the afterbody of pencil of still cannot conflicting after rotation push rod 4 ejects.But adopt above-mentioned syndeton just can solve this difficult problem, a body 2 is disassembled from a tail 1 and nib 3 respectively, then a tail 1 is directly connected with nib 3, at this moment the length of the whole Multifunction pen cap has just shortened, rotate the Distance Shortened between the bottom of push rod 4 and nib 3, extruding cushion block 12 just can extrude and be resisted against the afterbody of pencil by rotation push rod 4 tightly so slightly.
In addition, in order to when using this Multifunction pen cap suit gel ink pen or ball pen and suit compared with short pencil, the nib of pen core and the nib of pencil can both stably be fixed on the pen cap, when avoiding writing, nib shakes and causes the crooked or nib of handwriting to damage, preferably, the Multifunction pen cap also comprises a mouth 13 of truncated cone-shaped, the wide end of mouth 13 is connected with the bottom of nib 3, and the nib of pen core can stretch out pen cap outside through the wide end of a mouth 13 and narrow end successively; The diameter of the narrow end of mouth 13 is less than the diameter of the head of the pen core be connected with nib.Can change above-mentioned mouth 13 according to the actual conditions of different nib like this, expand the scope of application of this Multifunction pen cap further, that optimizes user writes impression.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
