Description

Automatically protect pen

Technical field

The utility model relates to a kind of pen, and the particularly a kind of ball pen that can protect pen core automatically, gel ink pen etc. are for the core pen.

Background technology

Our blanket ball pen, gel ink pen etc. do not have the function of automatic recovery for the core pen at present.The cap for brush must be put on or pressed spring after the people who uses uses and rebound automatically,, then can make nib exposed outside if forget aforesaid operations, an if automatic rolling or run into because of carelessness, drop on the ground, then may founder nib, it is no longer smooth to cause pen core to be write.

Summary of the invention

Problem to be solved in the utility model provides a kind of automatic protection pen that can protect nib automatically, and it can solve nib effectively and contact to earth and cause pen core to write slack problem.

For addressing the above problem, first kind of technical scheme of the present utility model is: protect pen automatically, comprise pen container and pen core, its special feature is: pen core passes the continuous pen cap, spring, is connected the rear end of pen container; Have sliding tray on the pen container, the rear end of tentacle is connected through the hinge at the middle part of the pen cap, and the front end of tentacle is positioned at the sliding tray outside.

Another kind of technical scheme of the present utility model is: protect pen automatically, comprise pen container and pen core, its special feature is: the pen cap one end is connected the rear end of pen core, and the other end is connected the rear end of pen container by spring; Have sliding tray on the pen container, the rear end of tentacle is connected through the hinge at the middle part of the pen cap, and the front end of tentacle is positioned at the sliding tray outside.

Automatic protection pen of the present utility model, its special feature is: described tentacle front end write under the state with the pen container front end apart from 3cm.

The utility model has just increased the pen cap that shields in common pen container; adopt after this structure; as long as the user no longer pins tentacle, pen core just can be automatically withdrawn in the pen container under the pen cap effect that is connected with spring, and nib just can not expose in the pen container outside like this.If even an automatic rolling or run into because of carelessness drops on the ground, nib can not contact to earth yet and cause it to be damaged.

Description of drawings

Below in conjunction with drawings and embodiments the utility model is described in further detail.

Fig. 1 be the utility model protect first kind of embodiment of pen automatically partly cut open structural representation.

Fig. 2 be the utility model protect second kind of embodiment of pen automatically partly cut open structural representation.

Wherein, 1 pen container, 2 pen cores, 3 tentacles, 4 sliding trays, 5 hinges, 6 pens cap, 7 springs.

The specific embodiment

Fig. 1 be the utility model protect first kind of embodiment of pen automatically partly cut open structural representation.Automatic protection pen of the present utility model comprises pen container 1 and pen core 2, and wherein, pen core 2 passes the continuous pen cap 6, spring 7, is connected the rear end of pen container 1; Have sliding tray 4 on the pen container 1, the rear end of tentacle 3 is connected the middle part of the pen cap 6 by hinge 5, and the front end of tentacle 3 is positioned at sliding tray 4 outsides.

The user is when using pen to write; as long as press tentacle 3 with hand; tentacle 3 will slide by sliding tray 4 on pen container 1; drive motion backward in the pen cap 6 by hinge 5; the pen cap 6 will be recovered in the pen container 1 like this; this moment, pen core 2 will break away from the protection of the pen cap 6, exposed in pen container 1 outside, so the user just can write smoothly.Since tentacle 3 front ends write under the state with pen container 1 front end apart from 3cm, and the best of it that hold a pen this moment just simultaneously can impel this user to form good pen holding posture.

After the user writes and finishes; the user unclamps tentacle 3; just no longer including masterpiece is used on the tentacle 3; this moment, spring 7 just had the trend of answer; under the elastic force effect of spring 7; the pen cap 6 skids off pen container 1 front end, and this moment, pen core 2 also just was within the pen cap 6, and the pen cap 6 just can play the good result of protection pen core 2 like this.The 6 proal whiles of the pen cap will drive tentacle 3 motion forward in sliding tray 4 by hinge 5, and the parts of whole so automatic protection pen just all return to initial conditions.

Fig. 2 be another kind of embodiment partly cut open structural representation.It has adopted another kind of automatic safeguard measure.Wherein, the pen cap 6 one ends are connected the rear end of pen core 2, and the other end is connected the rear end of pen container 1 by spring 7; Have sliding tray 4 on the pen container 1, the rear end of tentacle 3 is connected the middle part of the pen cap 6 by hinge 5, and the front end of tentacle 3 is positioned at sliding tray 4 outsides.

The user is when using pen to write, as long as pin tentacle 3 with hand, tentacle 3 will drive the pen cap 6 by hinge 5, and pen core 2 will expose pen container 1 under the effect of the pen cap 6, and this moment, the user just can write smoothly.Because the position of tentacle 3 under in working order is apart from 1 mouthful of 3cm place of pen container, and is the best of it that holds a pen at this moment.So also can impel and use this author to form good pen holding posture.

After the user write and finishes, the user unclamped tentacle 3, and tentacle 3 will drive the pen cap 6 pen core 2 is recovered in the pen container 1 under the elastic force effect of spring 7, so just can play the good result of protection pen core 2.
