Abstract

The utility model relates to a multipurpose pen cover which can be used as straight ruler, protractor and compass and integrates the function of writing. The utility model mainly comprises a pen hanger and a cover body, wherein, the cover body comprises a cover casing and an inner body. The upper part of the inner body is a frame, one edge of which is fixed with a long and thin steel needle, and the other three edges of which are fixed with a triangular pyramid body. A groove is arranged on one surface of the cover casing, and the pen hanger is an inner body frame by screws through the groove. When the frame moves downward, the steel needle is exposed as one leg of the compass. Circle can be drawn by pressing a ball-pen core on the triangular pyramid body. One surface of the cover casing is provided with scale, which can be used as the straight ruler. A dial scale is provided with the screw as the axis to measure the size of the angle.

Description

Multipurpose pen cover

The utility model relates to a kind of multipurpose pencil cap, particularly a kind ofly can do ruler, protractor, compasses and have the writing function cap for brush concurrently.

One 88218620.5 patent is arranged, relate to the Four-purpose pen cap on a kind of lettering pen, the hook that it is characterized in that the cap for brush is a miniature lettering pen, is fixed with the erasing rubber that can set up easily and take off at the top of cap body.This cap for brush can be done again except that having general utility functions and write and wiping usefulness, but purposes is still not extensive, uses inconvenient.

The utility model provides a kind of multipurpose, easy to use at the deficiencies in the prior art, is particularly suitable for the cap for brush that middle school student do how much topic usefulness.

The utility model is achieved in that this cap for brush mainly is made up of pen hanging, cap body.The cap body comprises cap shell and endosome two parts.Cap shell profile is a cuboid, is marked with scale at the edge that the pen hanging one side is installed, and can make ruler and draw straight line usefulness, can be used for measuring length again.Endosome comprises that cube frame and cylinder are contained in the cap shell, and framework is positioned at top, and cylinder is positioned at the bottom.Fix an elongated draw point on the rib of this framework, fix a triangular cone on its excess-three rib respectively, on the face of framework a screw is arranged.On the face of cap shell groove is arranged one, have a screw pen hanging to be fixed on the screw of endosome framework by groove.With this screw is axle outside equipped amount hornwork dial, is used to the size that takes measurement of an angle.Move down screw, pen hanging is moved down together with framework, draw point just exposes the pin as the circle rail from cap body lower end, draw less bowlder on an adjacent rib of its pin by refill for ball-point pen, when drawing, on the diagonal angle of its pin rib, press ball hair core than great circle.When needs take measurement of an angle size, with a limit of a side alignment angle of the cap for brush, loosening screw, the rotation pen hanging makes this side overlap with the another side at angle, reads the number of degrees that corresponding scale is the angle from dial.

The utility model compared with prior art has following advantage: of many uses, easy to use, this cap for brush is except that having general utility functions, can also do ruler, compasses, protractor use and have writing function concurrently, reach the purpose of one-object-many-purposes, be particularly suitable for middle school student and do topic usefulness how much.

Three-dimensional front schematic view of the present utility model among Fig. 1, Fig. 2 is the schematic diagram that the cap shell has groove, and Fig. 3 is the schematic perspective view of endosome framework, and Fig. 4 is the transverse cross-sectional view of endosome cylindrical portions may.

Wherein 1 is pen hanging, the 2nd, and cap shell, the 3rd, screw, the 4th, protractor dial, the 5th, endosome framework, the 6th, draw point, the 7th, triangular cone, the 8th, screw, the 9th, cap shell groove, the 10th, endosome cylinder.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: the length of the groove (9) on the distance between endosome framework (5) and the endosome cylinder (10) and the cap shell (2) is consistent.Loosening screw (3) moves down pen hanging (1) along groove (9), when moving to the bottom of groove (9), endosome framework (5) also moves down runs into cylinder (10), triangular cone (7) on the framework (5) is inserted the empty corner position between cylinder (10) and the cap shell (2), and the elongated draw point (6) on the framework (5) also exposes the cap body simultaneously.This draw point top is triangular prism shaped, and lower end 5mm is thin round needle, and this structure of draw point can make it insert empty corner position between cylinder and the cap shell (2) more firmly, avoids all around swinging, and is beneficial to the fixedly center of circle of picture bowlder.Draw bowlder through this pin as compasses, go up by last refill for ball-point pen in triangular cone (7) then, as another pin of garden rail, this garden pearl pen core is special triangular prism shaped.The limit of pen hanging (1) and the central lines of screw (3), when needs take measurement of an angle size, with the limit of pen hanging (1) with cap body one side alignment angle of screw (3) central lines, loosening then screw (3), rotation pen hanging (1) makes this limit overlap with the another side at angle, reads the number of degrees that corresponding scale is the angle from dial (4).

Claims
