Description
Technical field
The present invention relates to a kind of opening and closing device of uncovered retractable pen, particularly about utilizing the uncap opening and closing device of uncovered retractable pen of design of two-part.
Background technology
General pen can generally be divided into aqueous ink water-color paintbrush or oily ink pen according to the difference of using ink.Dry and can't write in air for fear of the ink long term exposure of writing end, therefore general common way is to utilize enclosing cover formula cap to come the writing end of airtight pen, and is dry to prevent ink.Yet, the pen of enclosing cover formula cap in use, and is on the one hand airtight or to open writing end very inconvenient with both hands, on the other hand airtight or when opening writing end, enclosing cover formula cap is also lost easily and is caused the ink of writing end dry, causes user's inconvenience part.Uncovered retractable pen in order further to solve the regret of all inconvenience of pen of above-mentioned enclosing cover formula cap, to develop then.By and large, the lid of uncovered retractable pen is to be hidden in the hollow shaft of a writing brush, utilize of the folding of the press device of shaft of a writing brush top with the press device of control uncovered retractable pen, reach purpose airtight and the unlatching writing end, therefore compared to the pen of enclosing cover formula cap, uncovered retractable pen has more the competitive advantage on the market.
See also Fig. 1, represent the fragmentary cross-sectional view of known uncovered retractable pen.Known uncovered retractable pen 100 comprises the hollow shaft of a writing brush 110, hollow epitheca 120 at least, writes member 130 and opening and closing device 140.The hollow shaft of a writing brush 110 has upper shed (figure does not illustrate) and under shed 113, wherein the hollow shaft of a writing brush 110 interior parallel arc-shaped protrusions 115 that are provided with in a spacing L place apart under shed 113.Hollow epitheca 120 is located in the hollow shaft of a writing brush 110, and hollow epitheca 120 has top 121 and bottom 123, and the diameter D of its middle and upper part 121 is greater than the diameter d of bottom 123.The upper end on top 121 is blind end (figure does not illustrate), and the lower end of bottom 123 then is an openend 127.Generally speaking, writing member 130 is to be located in the hollow epitheca 120 together and to have top 131 and bottom 133.Write the top 131 of member 130 and be located in the top 121 of hollow epitheca 120, to absorb and storage ink liquid.Bottom 123 and part that hollow epitheca 120 is located in 133 of the bottoms of writing member 130 extend in the top 121.Write member 130
Known uncovered retractable pen is to utilize various opening and closing devices to replace enclosing cover formula cap, to reach purpose airtight and the unlatching writing end.For example, as shown in Figure 1, opening and closing device 140 comprises hollow base 141, containment member 161, plastics fine rule 169 and elastic component 170 at least.Furthermore, see also Fig. 2, it illustrates the schematic perspective view of known opening and closing device.Hollow base 141 is arranged in outside the bottom 123 of hollow epitheca 120, and wherein hollow base 141 has upper shed 143 and under shed 145, and the sidewall 147 of hollow base 141 is provided with two relative grooves 149 from upper shed 143.Containment member 161 coats writing end (figure does not illustrate), and wherein containment member 161 has cover plate 163 and cover plate stay pipe 165, and a side 164 of cover plate 163 is hubbed at a side 166 of cover plate stay pipe 165.The sidewall of cover plate stay pipe 165 is provided with two relative grooves 167 outward.Plastics fine rule 169 wears groove 149, cover plate 163 and the groove 167 of hollow base 141 and is fastened in grooves on two sides 167.170 on spring is with being located in outside the bottom 123 of hollow epitheca 120, that is be located in the hollow base 141, and withstand hollow base 141 and cover plate stay pipe 165 with elastic force, and by plastics fine rule 169 link closely hollow base 141 and containment member 161, make cover plate 163 cover the lower surface 168 of cover plate stay pipe 165, and seal above-mentioned writing end (figure does not illustrate).
See also Fig. 3 (A), its opening and closing device that illustrates known uncovered retractable pen is at the schematic diagram that carries out the cover plate breakdown action.When for example utilizing the press device (figure does not illustrate) of being located at hollow epitheca 120 tops when hollow epitheca 120 is moved down together with writing end 135, the direction of opening and closing device 140 shown in arrow 171 descend push up arc-shaped protrusions 115 places to the hollow shaft of a writing brush 110 after, containment member 161 still continues to rise according to the direction shown in the arrow 171 and makes plastics fine rule 169 lax gradually, open cover plate 163 by lax plastics fine rule 169, make writing end 135 protrude in cover plate stay pipe 165, with the action of writing.
See also Fig. 3 (B), it illustrates opening and closing device according to known uncovered retractable pen at the schematic diagram that carries out the cover plate closing motion.In like manner, after finishing action of writing, can for example utilize press device (figure does not illustrate) that hollow epitheca 120 is moved up together with writing end 135, at this moment, hollow base 141 continues to rise according to the direction shown in the arrow 173,161 of containment members descend relatively and make plastics fine rule 169 tight gradually by the elastic force of spring 170, borrow the lower surface 168 that makes cover plate 163 cover cover plate stay pipes 165, and sealing writing end 135.In brief, the opening and closing device of known uncovered retractable pen is the design that utilizes two-part to uncap, promptly in conjunction with hollow base 141, containment member 161, plastics fine rule 169 and spring 170, to reach purpose airtight and the unlatching writing end.
Utilize the example of other various opening and closing devices,, one be listed as list of references of the present invention herein such as Taiwan patent announcement number the 341st, No. 920, No. the 4th, 969,764, United States Patent (USP) notification number and the 4th, 560, No. 298 revealers of institute of United States Patent (USP) notification number.
Yet the opening and closing device of known uncovered retractable pen still has many problems to wait to solve.At first, the assembling processing procedure of the opening and closing device of known uncovered retractable pen must utilize groove 149, cover plate 163 and the groove 167 that manually plastics fine rule 169 is worn hollow base 141, it is consuming time again that its processing procedure is not only assembled complexity, when producing in a large number more simultaneously, is difficult to accelerate processing procedure speed.Secondly, plastics fine rule 169 easily influences the switching effect of opening and closing device after using after a while because of elastic fatigue.
Therefore,, simplify fabrication steps and ease of assembly if can improve the structure of known opening and closing device, promoting processing procedure speed and yield, real for system pen industry relevant designer, user and producer look forward to jointly.
