Abstract

The utility model relates to a writing brush cap, composed of an upper semicircular plastic cap, a lower semicircular plastic cap and a clamp type steel wire spring. The upper semicircular plastic cap and the lower semicircular cap all forms semicircular tube bodies and are oppositely connected face to face, wherein, the middle parts thereof are connected with bumps inward and form supporting lever points. The rear parts of the upper semicircular plastic cap and the lower semicircular plastic cap all form a handle with an upward inclined plane. The arc-shaped bottom of the clamp type steel wire spring from above passes through slotted holes of the outer walls of the rear parts of the upper semicircular plastic cap and the lower semicircular cap, and the other two ends of the spring are respectively clamped on the front outer walls of the upper semicircular plastic cap and the lower semicircular cap. Thus, the integration of the writing brush cap is formed. The utility model has the advantages of simple structure, convenient plugging use and no damage of hair of a writing brush. Moreover, after the cap is plugged, the cap is not easy to fall off.

Description

Cassette elasticity Writing brush cap

The utility model relates to a kind of Writing brush cap.

Existing pointed Writing brush cap easily comes off, and writing brush uses the back to be difficult for putting into the pen cap because of the pen hair expands, and the last writing brush of student is wanted scouring of wool pen inconvenience after class, the hand of making dirty easily, and pointed Writing brush cap easily hinders the writing brush hair, influences its service life.

The purpose of this utility model is exactly in order to address the above problem, and a kind of sleeve writing brush convenience is provided and can damage a cassette elasticity Writing brush cap of hair.

Technical solution of the present utility model:

A kind of cassette elasticity Writing brush cap, it is characterized in that it is by upper semi-circle plastic sheath 1, lower half circle plastic sheath 2 and cassette wire spring 3 are formed, on, lower half circle plastic sheath 1,2 are semicircle body, they dock in opposite directions, their middle part all inwardly is connected with the projection 4 that docking point matches, this docking point is, lower half circle plastic sheath 1,2 supporting lever point 5, to should leverage points 5, on it, lower half circle plastic sheath 1,2 rear portion is an inclined-plane handle 6 that makes progress, cassette wire spring 3 is a U-shaped, its arcuate bottom is from last, lower half circle plastic sheath 1,2 the outer wall slotted eye 7 that is positioned at leverage points 5 rear positions passes, the two ends in addition of cassette wire spring 3 are connected to respectively, lower half circle plastic sheath 1, on 2 the outer wall that is positioned at leverage points 5 forward positions, constitute Writing brush cap integral body.

The utility model organically is combined as a whole clip structure and Writing brush cap first, finish the folding of Writing brush cap according to lever principle, so still can insert the pen cap easily after the pen hair of writing brush expands, and inserting the back nature blocks writing brush head, can not come off, can not damage pen hair, the hand of can not making dirty during student's scouring of wool yet.The utility model is simple in structure, makes easily, and cost is low, and is easy to use, can improve the service life of writing brush, easily promotes the use of.

Fig. 1 is that structure of the present utility model is shown the figure that determines.

Fig. 2 is the vertical view of Fig. 1.

As Fig. 1,2, when writing brush use up clean after, because the pen hair expands, its writing brush head external diameter is greater than the internal diameter of the former pen cap, be difficult for inserting the pen cap, this moment can with on, lower half circle plastic sheath 1, two inclined-plane handles, the 6 usefulness hands at 2 rear portions are inwardly pinched, make, lower half circle plastic sheath 1,2 anterior pen cap mouth is that fulcrum and the elastic force that overcomes cassette wire spring 3 outwards open with supporting lever point 5, pen cap mouth internal diameter is just greater than the external diameter of writing brush pen hair afterwards that expands like this, so can easily writing brush head be inserted, lower half circle plastic sheath 1,2 open in the mouth, as long as unclamp this moment, lower half circle plastic sheath 1,2 rear portion two inclined-plane handles 6, just close up under the restoring force effect of cassette wire spring 3 naturally in their front portion, the writing brush head cover is clamped, and effect is very good.Two bottoms of U-shaped cassette wire spring 3 are all outwards protruded and are formed a little shape U-shaped mouth 8 in the utility model, to be used for increasing the elastic force of spring 3.
