Abstract

The utility model relates to a pen barrel with the telescopic height capable of being changed by utilizing the magnetic principle. The telescopic pen barrel comprises an upper barrel body, a lower base sleeved and stacked outside the upper barrel body and an annular middle frame totally stacked above the lower base and used for preventing the upper barrel body from sliding out of the lower base. The upper barrel body is suspended above the lower base by configuring magnets with like magnetic poles in the corresponding positions of the upper barrel body and the lower base respectively, and the middle frame is adsorbed on the lower base by configuring magnets with opposite magnetic poles in the corresponding positions of the lower base and the middle frame sleeved on the outer wall of the upper barrel body, so that the upper barrel body is prevented from being rebounded out of the lower base, manually pressed down when the pen barrel is practically used and automatically rebounded after the pen barrel is used. The telescopic height of the pen barrel is changed by utilizing the magnetic principle that like poles repel and opposite poles attract, and the pen barrel has the advantages of simple structure, smart design and convenience for use.

Description

A kind of flexible pen container

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of pen container that utilizes the flexible height of magnetic principles conversion.

Background technology

Pen container is a kind of stationery that arrives commonly used in people's daily life, be used for taking in various writing implements, but the pen container height on existing market mostly is fixed, in use, tend to occur be placed in the pen container that easily allows pen container overturning, shorter pen be placed on level altitude in pen container as long ruler and be not easy again to take out, so just can occur placing when placing the instrument of different length dangerous, take inconvenient problem.

Summary of the invention

The purpose of this utility model is to provide a kind of telescopic pen container, and it can utilize the flexible height of magnetic principles conversion.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of flexible pen container, the lower bottom base that it comprises at least the ring-type upper shell of up/down perforation and is nested in the upper shell outside, described upper shell can slide up and down along the madial wall of lower bottom base, described flexible pen container also comprise one overlay lower bottom base top fully and be set on the upper shell lateral wall, with being restricted the ring-type center that upper shell skids off lower bottom base.

In a preferred embodiment, be provided with upper shell magnet on the base plane of described ring-type upper shell, be provided with the lower bottom base magnet corresponding with the upper shell magnet positions on the inner bottom surface of described lower bottom base, described upper shell magnet and lower bottom base magnet are the magnetic pole opposite setting.

In a preferred embodiment, be provided with the first magnet on the base plane of described ring-type center, be provided with second magnet corresponding with the first magnet positions on center on the top plan of described lower bottom base, described the first magnet and the second magnet are the incorgruous setting of magnetic pole.

In a preferred embodiment, the place extends upward the screens that forms an annular table scalariform along described upper shell bottom margin, and the upper plane of described screens can be resisted against on the bottom surface of described center fully.

In a preferred embodiment, described magnet is the soft magnet of sheet.

The beneficial effect of the flexible pen container of the utility model is: by the magnet of magnetic pole opposite is set respectively on the correspondence position of upper shell and lower bottom base, make upper shell be suspended in the top of lower bottom base, at lower bottom base be set on the correspondence position of the center on the upper shell outer wall the incorgruous magnet of magnetic pole is set respectively, center is adsorbed on lower bottom base, thus the outside of restriction upper shell emersion lower bottom base.Should design ingenious, simple in structure by flexible pen container.

Description of drawings

Fig. 1 is the three-dimensional structure diagram of flexible pen container in an embodiment.

The specific embodiment

Below in conjunction with specific embodiment and accompanying drawing, the flexible pen container of the utility model is described in further detail.

See also Fig. 1, a kind of flexible pen container, the lower bottom base 20 that it comprises at least the ring-type upper shell 10 of a up/down perforation and is nested in the upper shell outside, upper shell 10 can slide up and down along the madial wall of lower bottom base 20.Should comprise also that a use that is set on upper shell 10 lateral walls was restricted the center 30 that upper shell 10 skids off lower bottom base 20 outsides by flexible pen container, this center 30 can overlay the top of lower bottom base 20 fully.

Be provided with upper shell magnet on the bottom ring plain of upper shell, be provided with the lower bottom base magnet corresponding with the upper shell magnet positions on the inner bottom surface of lower bottom base, wherein, upper shell magnet and lower bottom base magnet are the magnetic pole opposite setting, understandable, according to the principle of magnet two like magnetic poles repel each other, upper shell can be suspended in the top of lower bottom base.

Be provided with the first magnet on the bottom ring plain of center, be provided with second magnet corresponding with the first magnet positions on center on the top plan of lower bottom base, wherein the first magnet and the second magnet are the incorgruous setting of magnetic pole, understandable, according to the principle that the magnet opposite sex is repelled each other, center 30 can be adsorbed on the top plan of lower bottom base 20.

Preferably, bottom margin place along upper shell extends upward the screens that forms an annular table scalariform, from the process that the bottom of center upwards passes, the upper plane of this screens can be resisted against on the bottom surface of center fully, continues to pass from center with the bottom of restriction upper shell when the top of upper shell.

The magnet that uses in the present embodiment is the soft magnet of sheet.

When reality was used, because the magnet two like magnetic poles repel each other, upper shell was suspended in the top of lower bottom base, when the stationery of taking lower than this flexible pen container height, can reduce height by the Manual press upper shell, take complete after, upper shell floats automatically.

To sum up, the flexible pen container of the utility model is by arranging respectively the magnet of magnetic pole opposite on the correspondence position of upper shell and lower bottom base, make upper shell be suspended in the top of lower bottom base, at lower bottom base be set on the correspondence position of the center on the upper shell outer wall the incorgruous magnet of magnetic pole is set respectively, center is adsorbed on lower bottom base, thus the outside of restriction upper shell emersion lower bottom base, during actual taking, but the Manual press upper shell reduces height, take complete after, upper shell also can float automatically.The flexible height that should flexible pen container utilizes magnet two like magnetic poles repel each other, the principle conversion pen container that there is a natural attraction between the sexes, have advantages of simple in structure, design is ingenious, easy to use.

Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art that can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
