Abstract

The utility model relates to a double-end rotary color pen which comprises two cores 4, wherein the color pen is composed of two connected rotary controllers, each rotary controller comprises a rotary shell 1, a pen cap tube holder 2 and a screw rod muffle 3, the lower end of the rotary shell 1 is connected with the pen cap tube holder, the middle chamber 11 of the shell 1 is engaged with a regular polygon end 6 at the upper end of the muffle 3, the end 5 of the core 4 is plugged in a chamber 7 of the muffle 3, a screw rod 8 at the lower end of the muffle 3 is sliding engaged with the internal screw 10 in the chamber 9 of the holder 2 via screws, the cores 4 can be wax crayon, oil painting rod, water-soluble oil painting rod or chalk. Compared with the prior art, the color pen has the advantages of sanitary property, easy operation and high working efficiency.

Description

The rotary crayon of double end

Technical field

The utility model relates to a kind of crayon, belongs to the cultural goods field.

Background technology

In the prior art, traditional crayon generally has only a kind of function, for example, a wax crayon has only a kind of color, will use multiple color during drawing, and the major defect of this traditional stationery is: must directly contact stationery with hand when children use, the hand of very easily making dirty influences healthy.In addition, owing to often to change different colored stationery, thereby use is very inconvenient, operating efficiency is also lower.

Summary of the invention

The purpose of this utility model provides the rotary crayon of a kind of double end, compares with the crayon of prior art, has advantages such as hygiene, easy to use and operating efficiency height.

The technical solution of the utility model is: comprise two pen cores; Described crayon is formed by connecting in opposite directions by two rotating control assemblies; Each rotating control assembly comprises rotational shell, pen cap base, screw sleeve composition; The circular hole chamber is connected with the external cylindrical surface of pen cap base in the lower end of described rotational shell, and the external cylindrical surface of interior circular hole chamber and pen cap base is for being slidingly matched; The stage casing inner chamber of described rotational shell is a hollow regular polygon cylinder shape; Described screw sleeve upper end is provided with the regular polygon end, and the stage casing inner chamber of described rotational shell matches with the regular polygon end that the screw sleeve upper end is provided with, and is slidingly matched each other; The inner chamber of described regular polygon end is a hollow structure; The end of described pen core is intercalated in the inner chamber, and both are for closely cooperating; The screw rod body of described screw sleeve lower end is intercalated in the inner chamber of pen cap base, and the inner chamber of described pen cap base is provided with internal thread, screw rod body and internal thread be spiral slide movingly.

When using this rotary crayon, as long as rotate rotational shell with hand, the stage casing inner chamber of rotational shell will drive the regular polygon end rotation of screw sleeve, because the effect of pen cap base inner chamber internal thread, screw sleeve will load pen core and is moved up or down, and has realized the action of refill expansion.Hand need not directly contact the stationery core when children used, and kept the cleaning of hand; And the two ends of pen are equipped with two cover whirligigs, are equipped with two pen cores.Therefore, it has advantages such as hygiene, easy to use and operating efficiency height.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further explained.As can be seen from the figure, the rotary crayon of this double end comprises two pen cores 4; Described crayon is formed by connecting in opposite directions by two rotating control assemblies; Each rotating control assembly comprises rotational shell 1, pen cap base 2, screw sleeve 3 compositions; Circular hole chamber 12 is connected with the external cylindrical surface 13 of pen cap base 2 in the lower end of described rotational shell 1, and the external cylindrical surface 13 of interior circular hole chamber 12 and pen cap base 2 is for being slidingly matched; The stage casing inner chamber 11 of described rotational shell 1 is a hollow regular polygon cylinder shape; Described screw sleeve 3 upper ends are provided with regular polygon end 6, and the stage casing inner chamber 11 of described rotational shell 1 matches with the regular polygon end 6 that screw sleeve 3 upper ends are provided with, and is slidingly matched each other; The inner chamber 7 of described regular polygon end 6 is a hollow structure; The end 5 of described pen core 4 is intercalated in the inner chamber 7, and both are for closely cooperating; The screw rod body 8 of described screw sleeve 3 lower ends is intercalated in the inner chamber 9 of pen cap base 2, and the inner chamber 9 of described pen cap base 2 is provided with internal thread 10, screw rod body 8 and internal thread 10 be spiral slide movingly.In the present embodiment, the stage casing inner chamber 11 of described rotational shell 1 is regular hexagon with the cross section of the regular polygon end 6 of screw sleeve 3 upper ends setting.

When using this rotary crayon, as long as rotate rotational shell 1 with hand, the stage casing inner chamber 11 of rotational shell 1 will drive regular polygon end 6 rotations of screw sleeve 3, because the effect of pen cap base 2 inner chambers 9 internal threads 10, screw sleeve 3 will load pen core 4 and moves up or down, and realized the action that pen core 4 is flexible.

Described pen core 4 can be wax crayon, artistic oil painting stick, water-soluble oil painting rod or chalk.
