Description
Technical field
The utility model relates to a kind of pen that prevents child.
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 children 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: a kind of pen that prevents child, comprise penholder, the pen cap and pen core, described pen core is arranged in described penholder, in the described pen cap, be provided with and pen core can be extruded to the depression bar of penholder, described pen cap opening part inner ring is provided with projection, in described penholder lateral wall upper end, is provided with the flange matching with described projection.When needs are used pen, first the pen cap is taken down from pen tip, then, be enclosed within the upper end of penholder, in the process of cover, the pen cap overlaps into from penholder upper end, simultaneously, depression bar in the pen cap withstand pen core by pen core toward pressing down, pen core extrudes penholder the most at last, simultaneously, projection in the pen cap combines with the flange of penholder lateral wall, thereby fix the position of pen core, after finishing using, the pen cap is restored.
In technique scheme, described pen cap opening part inner ring is parallel to each other be provided with two groups described in projection, described in every group, projection is arranged in same level uniformly, described penholder lateral wall upper end is parallel to each other be provided with two groups described in flange.Being connected of two groups of projections and two groups of flanges is set, after depression bar in the pen cap is pressed out pen core, between the pen cap and penholder, is connected better effects if.
In technique scheme, in described penholder, be provided with fixed head and portable plate, described fixed head is fixed on described penholder inwall, between described fixed head and described portable plate, by elastic parts, be connected, on described fixed head, offer the through hole matching with described pen core, end, described pen core upper end is fixedly connected with described portable plate.Depression bar is depressed portable plate, makes the pen tip of pen core be forced out penholder, and meanwhile, elastic parts shrinks, after finishing using, the pen cap is separated with penholder, affected by elastic parts, and pen core is automatically withdrawn in penholder, easy to use.
In technique scheme, on described penholder inwall, offer the chute matching with described portable plate, described portable plate is arranged in described chute.Portable plate is moved up and down in chute, the slip of portable propelling plate, the moving range of restriction portable plate, prevents that portable plate from rising too high under the elastic force impact of elastic parts, recovered slow.
The utility model compared with prior art, has following beneficial effect: the utility model can prevent that children from opening the cap for brush or pressing out pen core, safe.Being connected of two groups of projections and two groups of flanges is set, after depression bar in the pen cap is pressed out pen core, between the pen cap and penholder, is connected better effects if.Depression bar is depressed portable plate, makes the pen tip of pen core be forced out penholder, and meanwhile, elastic parts shrinks, after finishing using, the pen cap is separated with penholder, affected by elastic parts, and pen core is automatically withdrawn in penholder, easy to use.Portable plate moves up and down in chute, the slip of portable propelling plate, and the moving range of restriction portable plate, prevents that portable plate from rising too high under the elastic force impact of elastic parts, recovered slow.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model penholder schematic cross-section.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1 and Fig. 2, a kind of pen that prevents child, comprise penholder 1, the pen cap 2 and pen core 3, described pen core 3 is arranged in described penholder 1, is provided with and pen core 3 can be extruded to the depression bar 21 of penholder 1 in the described pen cap 2.
The described pen cap 2 opening part inner rings are parallel to each other be provided with two groups described in projection 22, described in every group, projection 22 is arranged in same level uniformly, described penholder 1 lateral wall upper end is parallel to each other be provided with two groups described in flange 11.Being connected of two groups of projections 22 and two groups of flanges 11 is set, after depression bar 21 in the pen cap 2 is pressed out pen core 3, between the pen cap 2 and penholder 1, is connected better effects if.
In described penholder 1, be provided with fixed head 12 and portable plate 13, described fixed head 12 is fixed on described penholder 1 inwall, between described fixed head 12 and described portable plate 13, by elastic parts 14, be connected, on described fixed head 12, offer the through hole matching with described pen core 3, described pen core 3 ends, upper end are fixedly connected with described portable plate 13.Depression bar 21 is depressed portable plate 13, makes the pen tip of pen core 3 be forced out penholder 1, and meanwhile, elastic parts 14 shrinks, after finishing using, the pen cap 2 is separated with penholder 1, affected by elastic parts 14, and pen core 3 is automatically withdrawn in penholder 1, easy to use.
On described penholder 1 inwall, offer the chute 4 matching with described portable plate 13, described portable plate 13 is arranged in described chute 4.Portable plate 13 is moved up and down in chute 4, the slip of portable propelling plate 13, the moving range of restriction portable plate 13, prevents that portable plate 13 from rising too high under the elastic force impact of elastic parts 14, recovered slow.
When needs are used pen, first the pen cap 2 is taken down from pen tip, then, be enclosed within the upper end of penholder 1, in the process of cover, the pen cap 2 overlaps into from penholder 1 upper end, the upper end here refers to one end contrary with nib, simultaneously, depression bar 21 in the pen cap 2 withstands portable plate 13 portable plate 13 is subdued, elastic parts 14 shrinks thereupon, and pen core 3 moves down simultaneously, pen core 3 extrudes penholder 1 the most at last, simultaneously, projection 22 in the pen cap 2 combines with the flange 11 of penholder 1 lateral wall, thereby fix the position of pen core 3, after finishing using, the pen cap 2 is restored to the pen tip that is enclosed within penholder 1.Even if child takes out the pen cap, pen core can not be pressed out, thereby prevent the damage that child uses pen core to cause clothes, furniture, or child's the body parts such as eyes are caused damage.
