Description
Technical field
The utility model relates to the pen that children cannot open.
Background technology
Pen, is the mankind's a invention greatly, is for the instrument of writing or painting.In having child's family, 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.
Utility model content
The utility model is not enough for prior art, provides a kind of and 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 utility model is solved by following technical proposals: the pen that children cannot open, 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 shape of threads, 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 to the inclined-plane of the same side inclination, 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, on described pen core lower outside wall, be fixedly installed baffle plate No. one, on described penholder, offer the hole that several distribute ringwise, be provided with depression bar through described hole and extend in described penholder, the end, one end that described depression bar is positioned at described penholder is fixedly installed baffle plate No. two, between described No. two baffle plates and described penholder madial wall, by an elastic parts, interconnect.After pen uses, pull bar is drawn outward toward through hole, pen core top is separated with pen core bottom, simultaneously, No. two baffle plates be positioned at a baffle plate under, block a baffle plate and move down, while preventing that pen core top from also a little contacting with pen core bottom, pen core can be pressed out penholder, thereby prevented child's pen of playing, caused unnecessary loss or injury.In the time of need to using, pushing drawing rod, pen core top is connected with pen core bottom, again depression bar is pressed in penholder, elastic parts is shunk, thus make No. two baffle plates leave a baffle plate under, make in a baffle plate and No. two baffle plate vertical direction not overlapping, thereby pen core can be depressed, normally use, decontrol in use the normal use that depression bar does not affect pen yet.
In technique scheme, two inclined-planes of two faces that described pen core top is in contact with one another with described pen core bottom for mutually mating.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 penholder madial wall, offer the semicircle chute matching with described pen core top.Facilitate moving horizontally of pen core top, after preventing that pen core top is separated with pen core bottom, the dropping of pen core top.
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, a described baffle plate place face and described No. two baffle plate place faces are parallel to each other.A baffle plate and No. two baffle plate contact-making surfaces are maximized, make No. two baffle plates best to the fixed effect of a baffle plate.
In technique scheme, described depression bar is positioned on one end end face outside described penholder and is provided with ridge.Increase the frictional force between depression bar and finger, person's operation easy to use.
The utility model compared with prior art, has following beneficial effect: the utility model 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 separated 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.A baffle plate and No. two baffle plate contact-making surfaces maximize, and make No. two baffle plates best to the fixed effect of a baffle plate.Ridge increases the frictional force between depression bar and finger, person's operation easy to use.
