Description
Technical field
The utility model relates to safety pen.
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.
Utility model content
The utility model, for prior art deficiency, provides one 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: safety pen, comprise penholder, the pen cap and pen core, described pen core is arranged in described penholder, in the described pen cap, be provided with the depression bar that pen core can be extruded to penholder, described pen cap opening part inner ring is provided with projection, be provided with in described penholder lateral wall upper end the flange matching with described projection, on described penholder madial wall, be fixedly installed a fixed head of several annulars, all described annular fixed heads are arranged in parallel, on described pen core, be fixedly installed several levers, described lever is positioned at described annular fixed head top, on all described annular fixed heads, all offer the open slot matching with described lever, on described pen core, be also provided with push rod, on described penholder, also offer the one number service hole of passing for all described push rods.When needs use pen, rotating push-rod, all levers are all aimed to the open slot on a corresponding annular fixed head, again 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 withstands pen core and presses down past pen core, 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, pen core is recovered in penholder, move horizontally push rod, pen core is rotated, thereby make lever leave the open slot on a fixed head of annular, again the pen cap is restored.
In technique scheme, projection described in what described pen cap opening part inner ring was parallel to each other be provided with two groups, described in every group, projection is arranged in same level uniformly, flange described in what described penholder lateral wall upper end was parallel to each other be provided with two groups.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, be connected by elastic parts, 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, and 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.
In technique scheme, on the end, outer end of described push rod, be provided with striped.Increase and the friction of pointing, facilitate mobile putter.
In technique scheme, the inner ring diameter of a described annular fixed head and described pen core diameter match.Make lever entirety all annular a fixed head on, fixed effect is better.
In technique scheme, on described penholder lateral wall, be also arranged with protective sleeve.The effect that protective sleeve mainly plays is to block the one number service hole of offering on penholder, makes child can't see push rod, cannot use push rod, further prevents that child from releasing penholder by pen core, and protective sleeve can also protect penholder to prevent from being scratched.
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, and 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.Striped increases the friction with finger, facilitates mobile putter.Lever entirety is all on a fixed head of annular, and fixed effect is better.The effect that protective sleeve mainly plays is to block the one number service hole of offering on penholder, makes child can't see push rod, cannot use push rod, further prevents that child from releasing penholder by pen core, and protective sleeve can also protect penholder to prevent from being scratched.
