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: prevent the safety pen that children open, comprise penholder, the pen cap and pen core, described pen core is arranged in described penholder, described pen cap opening part inner ring is provided with projection, described penholder pen tip is provided with the flange matching with described projection, in the described pen cap, be provided with the depression bar that pen core can be extruded to penholder, described projection below is provided with first screw thread, be provided with at described penholder lateral wall upper end the second screw thread matching with described first screw thread, on described pen core, offer annular groove, be provided with the flexible attachment matching with described annular groove, described flexible attachment is arranged in described groove, in described flexible attachment, be fixedly connected with depression bar No. one, on described penholder, offer the one number service hole matching with a described depression bar, a described depression bar passes described one number service hole and extends to outside described penholder.When needs use pen, first press depression bar No. one, flexible attachment is expanded, flexible attachment makes flexible attachment can make pen core pass after expanding, again the pen cap is taken down from pen tip, then, be enclosed within the upper end of penholder, in the process of cover, second threaded engagement on first screw thread and penholder lateral wall in the pen cap is threaded, 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, can rely on the degree of depth being threaded to decide and pen core need to be ejected to the length outside penholder, after finishing using, the pen cap is restored, pen core restores, flexible attachment is connected with annular groove, fix pen core.
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, be provided with two depression bars in described flexible attachment, two described depression bars are located along the same line.Press down and flexible attachment will be strutted to effort by a depression bar, use two depression bars simultaneously by relatively laborsaving, on same straight line, convenient finger is pressed.
In technique scheme, a described depression bar end surface is provided with ridge.Increase the frictional force between bigger depression bar and finger, facilitate depression bar of finger presses.
In technique scheme, a described depression bar end is fixedly connected with the block that diameter is greater than a described depression bar diameter.Prevent that a depression bar is pushed in penholder, thereby avoid the pen core penholder that cannot be pressed out.
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.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.Press down and flexible attachment will be strutted to effort by a depression bar, use two depression bars simultaneously by relatively laborsaving, on same straight line, convenient finger is pressed.No. one depression bar end surface arranges ridge, increases the frictional force between bigger depression bar and finger, facilitates depression bar of finger presses.The setting of block prevents that a depression bar is pushed in penholder, thereby avoids the pen core penholder that cannot be pressed out.
