Description

The roller shutter type painting and calligraphy board

The utility model relates to a kind of painting and calligraphy board, belongs to the school supply and stationery technical field.

Present blackboard has fixed blackboard and portable blackboard two classes.Fixed blackboard mostly is frosted glass blackboard, cement blackboard or wooden blackboard, their dull colorings, dust pollution seriously and very heavy, can only be in indoor application, for by two or three Reelable blackboards that plate is formed, have one or two can be movable, but its essence is still a kind of fixedly blackboard, and cost be too high; Portable blackboard mostly is plastic plate, wood based panel or metallic plate, no matter the size of blackboard, all exist and move and carry inconvenient defective, and the cost that has is too high, the dust pollution that has is serious, hanging on the wall of having is not attractive in appearance, and what have writes and show that the writing on the blackboard content is inconvenient or be unfavorable for that the learner concentrates one's energy to pay attention to the class.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to manufacture, easy to use, of many uses and be applicable to the roller shutter type painting and calligraphy board of various occasions.

The purpose of this utility model is achieved through the following technical measures:

The roller shutter type painting and calligraphy board is made up of shell, last axle, lower shaft and plate face, and the two ends of plate face are separately fixed on axle and the lower shaft, and Upper shaft sleeve is cased; Respectively there is a Mainspring type spring at the two ends of last axle, and an end of spring is fixed in the spring case, and the other end is fixed on the axle; Spring case is fixed on outer casing end, and respectively there is an end cap at the shell two ends, and a side of shell has one to be convenient to the notch that the plate face passes in and out, and the opposite side relative with the shell notch has one to be convenient to handle portable or that hang; Respectively there is a locator at the two ends of lower shaft, and locator can be made Ω shape locator, also can make eccentric wheel type locator or spring clip type locator; The plate face can be made with cloth and add black or other colors that shellac varnish is handled as basal plane, also can make with blank sheet of paper to add the blank that membrane is handled as basal plane, also can directly make with the soft plastics thin plate of white or other colors.The roller shutter type painting and calligraphy board can be made different size according to different needs, for undersized roller shutter type painting and calligraphy board, also can only at an end of last axle the Mainspring type spring be installed.Shell available metal thin plate, plastic plate or other material that is suitable for are manufactured.
