Abstract

A pen capable of automatically protecting a pen point is characterized in that a movable pen cap (2) which is partially inserted into a pen holder (8) is disposed in the front of the pen holder (8), the pen cap (2) is in a cylinder shape with a front opening and a rear opening, the rear of the pen cap is provided with a sliding surface (4) with a wide back and a narrow front, and a baffle platform (7) integrated with the pen holder is arranged behind the pen cap (2) inside the pen holder. A spring (6) is disposed between the rear end of the pen cap and the baffle platform (7), a pair of press heads (5) is positioned outside the pen holder (8) corresponding to the position of the sliding surface (4) and penetrates through the pen holder, and the front end of each press head is provided with a slider (9). The pen capable of automatically protecting the pen point overcomes the shortcoming of manual capping of the pen cap, is worry-saving and trouble-saving, capable of timely providing automatic protection for the pen point when not being used, low in cost, and applicable to various hard pens such as pens, gel ink pens, ball-point pens and the like, and the service life of the pen can be effectively prolonged.

Description

Can protect the pen of nib automatically

Technical field

The utility model relates to pen, is a kind of pen that can protect nib automatically specifically.

Background technology

Nib is a most important parts, and damages easily.Usually we need cover the pen cap and protect nib; must take off the pen cap in use just can write; but often in use can not cover the pen cap at any time and protect nib; this moment just might be because pen be slipped on the ground; perhaps take and meet because of carelessness on other article when mobile, not only stained other article easily also are easy to nib is damaged; in case nib is damaged, this pen has just been scrapped mostly.Therefore very important to the protection of nib, our the normally used pen cap that manually puts is but not quite convenient, can not protect nib timely.

Summary of the invention

The purpose of this utility model provides a kind of pen that can protect nib in time, automatically.

The described pen that can protect nib automatically; comprise pen container, pen core; it is characterized in that: be provided with the movable pen cap that is partially submerged in the pen container in the front portion of described pen container; the described pen cap is the tubular of rear and front end part opening; this pen cap rear portion be provided with the back wide before narrow sliding surface; after the pen cap of pen container inside, be provided with retaining platform with the pen container one; between pen cap rear end and the retaining platform spring is housed; with the pen container of sliding surface correspondence position outside be provided with a pair of press head, described press head passes across pen container and is provided with slide block at its front end.

The utility model has overcome the drawback of the manual cover pen cap, not only save worry, save trouble, and can be timely provide automatic protection to nib in user mode not, and with low cost, be applicable to various hard-tipped pen such as pen, gel ink pen, ball pen, can effectively prolong the service life of pen.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: the 1-nib, the 2-pen cap, the 3-pen core, the 4-sliding surface, the 5-press head, the 6-spring, 7-keeps off platform, 8-pen container, 9-slide block.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: the pen that as shown in Fig. 1 embodiment, can protect nib automatically; comprise pen container 8, pen core 3; be provided with the movable pen cap 2 that is partially submerged in the pen container 8 in the front portion of described pen container 8; this activity pen cap 2 can move forward and backward in pen container flexibly; the described pen cap 2 is tubulars of rear and front end part opening; the opening of front end is to be convenient to expose nib 1, and the opening of rear end can pass pen core 3.

These pen cap 2 rear portions be provided with the back wide before narrow sliding surface 4, this sliding surface 4 can be made tubular, the rear portion diameter also can be provided with beloid sliding surface structure at the outer surface of the pen cap greater than anterior diameter, purpose is to be convenient to the slip of stressed front and back.

After the pen cap 2 of pen container 8 inside, be provided with the retaining platform 7 with the pen container one, between the pen cap 2 rear ends and the retaining platform 7 spring 6 be housed.Therefore the rear end of the pen cap 2 is not all open, only is provided with opening passing pen core 3 places.The pen cap 2 rear ends and the retaining spring 6 between the platform 7 pushes away the pen cap forward, does not receive that at the pen cap under the situation of external force, the pen cap can cover nib fully.

With the pen container 8 of sliding surface 4 correspondence positions outside be provided with a pair of press head 5, described press head 5 passes across pen container and is provided with slide block 9 at its front end.Just in time in the face of the sliding surface of the pen cap, when press head 5 was under pressure, slide block was pressed on the sliding surface slide block 9, and this moment, the pen cap was subjected to mobile backward component, can overcome the elastic force of spring 6, moved backward, exposed nib 1, and promptly can write this moment.Therefore nib only exposes at the finger Shi Caihui that firmly writes, and when stopping to write, finger can not exerted oneself, and the pen cap promptly can move forward, and covers the pen cap, and the pen cap is in time protected.

Claims

1. the pen that can protect nib automatically; comprise pen container; pen core; it is characterized in that: be provided with the movable pen cap (2) that is partially submerged in the pen container (8) in the front portion of described pen container (8); the described pen cap (2) is the tubular of rear and front end part opening; this pen cap rear portion be provided with the back wide before narrow sliding surface (4); the pen cap (2) in pen container inside is provided with the retaining platform (7) with the pen container one afterwards; between pen cap rear end and the retaining platform (7) spring (6) is housed; with the pen container (8) of sliding surface (4) correspondence position outside be provided with a pair of press head (5), described press head (5) passes across pen container and is provided with slide block (9) at its front end.
