Description
Technical field
The present invention relates to the safety pen that prevents that child from opening.
Background technology
Pen, is the mankind's a invention greatly, is for the instrument of writing or painting.In the family that has child, after adult uses pen, tend in the place that uses pen, pen be left over, child often can take up one's pen when toy use.General pen, child is easy to press out pen core or opens the pen cap, and child holds Pen Association's coating and drawing at random, made dirty clothes or furniture, and nib is sharper, draws on furniture and can on furniture, mark one trace, damage furniture, stamp, to eyes, accidentally just can injure eyes, very dangerous.
Summary of the invention
The present invention is directed to prior art deficiency, provide one can prevent that child from opening the cap for brush or pressing out pen core, safe pen.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: prevent the safety pen that child opens, comprise penholder, the cap for brush, drive unit and pen core, described pen core is arranged in described penholder, on described pen core, be provided with bulge loop, described pen core front end sleeve is provided with elastic parts and limits described elastic parts by described bulge loop and moves upward, described drive unit comprises connecting rod, dop and the positioner matching with described dop, the described cap for brush is set on described connecting rod, described connecting rod is fixedly connected with described dop, described dop is connected with described pen core, described dop side is provided with ridge, described cap for brush lower end is provided with several grooves, all described grooves connect and are screw-like, described ridge upper end and described groove match, described positioner is fixed on the inwall of described penholder, described positioner comprises several draw runners of even setting, the end of all described draw runners is the inclined-plane tilting to the same side, between adjacent draw runner, be arranged at intervals with barrier rib, described pen core comprises pen core top and pen core bottom, described pen core top is connected with described dop, described bulge loop is arranged on described pen core bottom, on described penholder, be positioned at place, described pen core top and offer through hole, being provided with pull bar is fixedly connected with described pen core top through described through hole, described pen core bottom offers a groove of annular, be provided with the flexible attachment matching with a described annular groove, described flexible attachment is arranged in a described groove, in described flexible attachment, be fixedly connected with depression bar, on described penholder, offer the one number service hole matching with described depression bar, described depression bar passes described one number service hole and extends to outside described penholder.After pen uses, pen core is recovered in penholder, and flexible attachment, in a groove of annular, is fixed pen core, pen core can not be moved up and down,, pull bar is drawn outward toward through hole meanwhile, pen core top is separation with pen core bottom, after separating, pressing the cap for brush cannot press out pen core in penholder again, thereby has prevented child's pen of playing, and causes unnecessary loss or injury.When needs are used pen, first pull bar is pushed away in penholder, after pen core top is connected with the contact of pen core bottom, press again moulded rod, flexible attachment is expanded, and flexible attachment makes flexible attachment can make pen core pass after expanding, then presses the cap for brush pen core is pressed out in penholder, after pen core presses out, unclamping flexible attachment does not affect the normal use of pen yet.
In technique scheme, two faces that described pen core top is in contact with one another with described pen core bottom are two inclined-planes that mutually mate.After two the inclined-plane contact of coupling connects mutually, one of them inclined-plane has an effect stopping to another inclined-plane, thereby make user can understand clearly now pen core top, is connected completely with pen core bottom.
In technique scheme, on described pull bar, be provided with kink, described pull bar can be bent by described kink.Pull bar pulls open pen core top and pen core bottom after separating, bending pull bar, thus making, pull bar not being bent restorable time, pen core top to be connected with pen core bottom, the while also cannot press out pen core to penholder.
In technique scheme, be provided with two depression bars in described flexible attachment, two described depression bars are located along the same line.By a depression bar, press down and flexible attachment will be strutted to effort, use two depression bars simultaneously by relatively laborsaving, on same straight line, convenient finger is pressed.
In technique scheme, described depression bar end surface is provided with ridge.Increase the frictional force between depression bar and finger, facilitate finger presses depression bar.
In technique scheme, described depression bar end is fixedly connected with the block that diameter is greater than described depression bar diameter.Prevent that depression bar is pushed in penholder, thereby avoid the pen core penholder that cannot be pressed out.
The present invention compared with prior art, has following beneficial effect: the present invention can prevent that child from opening the cap for brush or pressing out pen core, safe.After two the inclined-plane contact of coupling connects mutually, one of them inclined-plane has an effect stopping to another inclined-plane, thereby make user can understand clearly now pen core top, is connected completely with pen core bottom.Chute is set and facilitates moving horizontally of pen core top, after preventing that pen core top is separation with pen core bottom, the dropping of pen core top.Pull bar pulls open pen core top and pen core bottom after separating, by kink bending pull bar, thereby makes, pull bar not being bent restorable time, pen core top to be connected with pen core bottom, and the while also cannot press out pen core to penholder.By a depression bar, press down and flexible attachment will be strutted to effort, use two depression bars simultaneously by relatively laborsaving, on same straight line, convenient finger is pressed.Depression bar end surface arranges ridge, increases the frictional force between depression bar and finger, facilitates finger presses depression bar.The setting of block prevents that depression bar is pushed in penholder, thereby avoids the pen core place's penholder that cannot be pressed.
