Description

A kind of mechanical pencil that can release and automatically retract automatically pen core
Technical field
The present invention relates to signature pen technical fields, refer in particular to a kind of mechanical pencil that can release and automatically retract automatically pen core.
Background technique
The automatic structure of mechanical pencil by invention at the beginning of use till today always, bring considerable influence to the mankind, improve Social production efficiency, forms new industrial chain.But for current mechanical pencil structure again without innovation, enterprise and consumption are all full It is enough to only need the i.e. workable mechanical pencil of subjective action twice, variation and social productive forces and production method due to social contradications Progress, consumer has mechanical pencil product new requirement, and mechanical pencil structure still has leeway and the power of innovation.
Summary of the invention
In view of the deficiencies of the prior art, it the present invention provides the mechanical pencil that one kind could release and withdraw automatically pen core, uses Machine Design, realizes the automatic effect for releasing pen core by rotate gear component, automatically retracts pen core by the elastic force of spring Effect opens pen without extra subjective behavior to reach, and structure is simple, easy to operate, practical.
To achieve the goals above, the technical solution that the present invention applies is as follows:
A kind of mechanical pencil that can release and automatically retract automatically pen core, including be set to a shell in gear assembly, pen core with Spring, pen core are set in a shell, and pen core tail portion is equipped with rack gear, and connection is engaged with rack in gear assembly, and gear assembly is correspondingly arranged There is limit assembly, one end limit of spring is placed on the head of pen core, and the other end limit of spring contacts on the inner wall of a shell.
Furthermore, the gear assembly includes gear wheel and pinion gear, and gear wheel and pinion gear pass through shaft can Rotation is set in a shell, and the exposed setting in gear wheel part, gear wheel engages connection with pinion gear, and company is engaged with rack in pinion gear It connects.
Furthermore, the gear wheel includes master gear and pinion, and pinion is fixed on master gear, pinion with Pinion gear engagement connection, main gear section exceptionally reveal setting.
Furthermore, described shell is equipped with the gear opening that main gear section can be made exceptionally to reveal setting.
Furthermore, the limit assembly includes the pen clip being fixed on a shell, and pen clip is equipped with and gear assembly The gear position limiting bayonet that gear wheel is correspondingly arranged.
The invention has the advantages that:
The present invention uses Machine Design, realizes the automatic effect for releasing pen core by rotate gear component, passes through spring Elastic force automatically retracts the effect of pen core, opens pen without extra subjective behavior to reach, and structure is simple, easy to operate, real It is strong with property.

Specific embodiment
Technical solution of the present invention is illustrated with embodiment with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, the mechanical pencil of pen core can be released and be automatically retracted automatically to one kind of the present invention, including set In gear assembly, pen core 5 and spring 6 in shell 7, pen core 5 is set in a shell 7, and 5 tail portion of pen core is equipped with rack gear 4, gear assembly Connection is engaged with rack gear 4, using such structure setting, under the mating reaction of gear assembly and rack gear 4, is realized pen core 5 The purpose of release, gear assembly are correspondingly arranged on limit assembly, are limited by limit assembly to gear assembly, make pen core 5 Always be in release state, pen core is withdrawn when avoiding writing, and the limit of one end of spring 6 is placed on the head of pen core 5, spring 6 it is another One end limit contacts on the inner wall of a shell 7, and using such structure setting, when pen core 5 is pushed outwardly, spring 6 is by power Extruding under the bounce effect of spring 6, realize the mesh that withdraws pen core 5 when limit assembly does not limit gear assembly 's.
More specifically, the gear assembly includes gear wheel 2 and pinion gear 3, and gear wheel 2 and pinion gear 3 are by turning Axis is rotatably set in a shell 7, the exposed setting in 2 part of gear wheel, and gear wheel 2 engages connection with pinion gear 3, pinion gear 3 with The engagement connection of rack gear 4.2 band of gear wheel is realized by stirring 2 part of gear wheel of exposed setting using such structure setting The effect that dynamic pinion gear 3 rotates, then slided by pinion gear 3 with carry-over bar 4, realize the purpose for releasing pen core 5.
As shown in Figure 1, gear wheel 2 drives pinion gear 3 to rotate counterclockwise, at this time small tooth when rotating clockwise gear wheel 2 3 promotion rack gear 4 of wheel slides to the right, so that pen core 5 be released, is limited gear assembly by limit assembly, at this time automatically Pen can be used for writing use, and after limit assembly is detached from gear assembly, under the bounce effect of spring 6, pen core 5 is withdrawn It in shell 7, is slided to the left with hour rack 4, and pinion gear 3 is driven to rotate clockwise, pinion gear 3 drives gear wheel 2 counterclockwise Rotation, until pen core 5 resets.
More specifically, the gear wheel 2 includes master gear 21 and pinion 22, and pinion 22 is fixed on master gear 21 On, pinion 22 engages connection, the exposed setting in 21 part of master gear with pinion gear 3.Using such structure setting, pass through lever Very comfortable when principle releases pen core 5.
More specifically, described shell 7 is equipped with the gear opening 70 that can make the exposed setting in 21 part of master gear.Using this The structure setting of sample is convenient for the exposed design of master gear 21.
In practical application, the diameter of master gear 21 is greater than the caliber of a shell 7.
More specifically, the limit assembly includes the pen clip 1 being fixed on a shell 7, and pen clip 1 is equipped with and gear assembly The gear position limiting bayonet 10 that is correspondingly arranged of gear wheel 2.Using such structure setting, realized by stirring pen clip 1 to gear Component blocking and loosening, to realize the effect limited to gear assembly.
In practical application, pen clip 1 of the present invention is bent and contacts to shell 7 near gear position limiting bayonet 10 Setting, good appearance and have certain toughness.
It should be noted that it is entirely Machine Design that the present invention, which releases and withdraw automatically the mechanical pencil structure of pen core 5, if When mechanical pencil is sandwiched on object, when to take out in use, the object accompanied between pen clip 1 and gear assembly and shell 7 due to Frictional force drives gear assembly rotation, and when object takes out completely, as pen core 5 releases state at this time, if mechanical pencil is not sandwiched in When on object, then artificial rotate gear component is needed to realize the effect for releasing pen core 5, is opened with reaching without extra subjective behavior Pen increases working efficiency, promotes the purpose that work enjoyment relieves stress.
The above technical solution in the embodiment of the present invention is described, but the invention is not limited to above-mentioned specific Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much Form, within these are all belonged to the scope of protection of the present invention.
