Description
Technical field
The utility model relates to the pen that prevents child.
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: the pen that prevents child, 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, is provided with at described penholder lateral wall upper end the second screw thread matching with described first screw thread.When needs use pen, first the pen cap is extracted from pen tip, then, be enclosed within the upper end of penholder, in the process of cover, the 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, meanwhile, 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.
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.
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.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: referring to Fig. 1, prevent the pen of child, comprise penholder 1, the pen cap 2 and pen core 3, described pen core 3 is arranged in described penholder 1, the described pen cap 2 opening part inner rings are provided with projection 21, described penholder 1 pen tip is provided with the flange 11 matching with described projection 21, in the described pen cap 2, be provided with the depression bar 22 that pen core 3 can be extruded to penholder, described projection 21 belows are provided with first screw thread 4, be provided with at described penholder 1 lateral wall upper end the second screw thread 5 matching with described first screw thread 4.
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, be connected by elastic parts 14, 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 22 is depressed portable plate 13, makes the pen tip of pen core 3 be forced out penholder 1, and meanwhile, elastic parts 14 shrinks, and 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 6 matching with described portable plate 13, described portable plate 13 is arranged in described chute 6.Portable plate 13 is moved up and down in chute 6, 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 use pen, first the pen cap 2 is extracted from pen tip, then, be enclosed within the upper end of penholder 1, in the process of cover, second screw thread 5 cooperations on first screw thread 4 in the pen cap 2 and penholder 1 lateral wall are threaded, simultaneously, depression bar 22 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, can rely on the degree of depth being threaded to decide and pen core 3 need to be ejected to the length outside penholder, what be namely threaded is darker, it is also just larger that pen core 3 stretches out length outside penholder 1, can easily control pen core 3 and stretch out the length outside penholder 1.After finishing using, the pen cap 2 is restored to the pen tip that is enclosed within penholder 1.Even if child extracts the pen cap, pen core can not be pressed out, thereby prevent the damage that child uses pen core to cause clothes, furniture, or the body part such as eyes to child causes damage.
