Abstract
An adjustable curved surface blackboard comprises a rectangular blackboard body and a blackboard surface, a frame is arranged around the blackboard body, the positions of the surfaces of the blackboard body, which are close to corners of the frame, are provided with a groove respectively, an extension rod is fixedly connected into the corresponding groove respectively, the other end of the extension rod is fixedly connected with the blackboard surface, and a protrusion block is arranged on the positions of the blackboard surface respectively, which correspond to the positions of the extension rods; the area of the blackboard surface is identical with that of the inside of the frame. During usage, if light reflection occurs and causes adverse affect on reading of the writing on the blackboard of students, a user can hold the protrusion blocks of the blackboard surface to pull up two sides of the blackboard surface to form the curved surface blackboard to facilitate the reading of the writing on the blackboard of students; usually the user does not need to pull up the blackboard surface, and the curved surface blackboard can serve as a plane blackboard. The adjustable curved surface blackboard has the advantages that the structure is simple and reasonable, a plane blackboard and a curved surface blackboard are integrated, the curved surface of the curved surface blackboard can be adjusted as needed, and the usage convenience for teachers and students can be achieved.
Description
Technical field the utility model relates to a kind of realia, especially a kind of adjustable Curved surface blackboard.
background technology is well-known, blackboard is that teachers and students go up one of requisite realia of class hour, but existing blackboard function singleness, teachers and students' use needs can not have been met, for example: existing blackboard can not be avoided reflective problem, the position of especially close blackboard both sides, reflective phenomenon is even more serious, if writing on the blackboard is write when the position near blackboard both sides, probably be sitting in the student of back, classroom due to reflective problem, do not see the writing on the blackboard of blackboard, in order to solve such problem, people have designed Curved surface blackboard, but existing Curved surface blackboard cannot be adjusted, and existing Curved surface blackboard and plane blackboard are two independently individualities, be not integrated in one, be not easy to teachers and students' choice for use as required, brought inconvenience for teachers and students.
Summary of the invention the utility model, for the deficiencies in the prior art, provides a kind of adjustable Curved surface blackboard, to solve existing Curved surface blackboard, has in use inconvenient problem.
The utility model comprises rectangle plate body and blackboard panel, at the plate body periphery, be provided with frame, position in close frame corner, the surface of plate body is provided with groove, and in groove affixed expansion link, at the affixed blackboard panel of the other end of expansion link, and be provided with projection in the position of the corresponding expansion link of blackboard panel; The blackboard panel area is identical with the frame internal area.
After adopting said structure, during use, if reflective phenomenon occurs, while affecting students reading writing on the blackboard, can hold the projection on blackboard panel surface by a side pull-up of blackboard panel, form Curved surface blackboard, to facilitate students, read writing on the blackboard; And, at ordinary times, need not, by the blackboard panel pull-up, can be used as the plane blackboard and use.
The beneficial effects of the utility model are: simple in structure, structure rationally, is integrated in one plane blackboard and Curved surface blackboard, and the curved surface of Curved surface blackboard can adjust as required, and it is convenient to teachers and students' use, to have brought.
Description of drawings 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment as shown in Figure 1 and Figure 2, in a kind of schematic diagram of adjustable Curved surface blackboard, comprise rectangle plate body 1 and blackboard panel 2, at the plate body periphery, be provided with frame 3, position in close frame corner, the surface of plate body is provided with groove 4, and in groove affixed expansion link 5, at the affixed blackboard panel of the other end of expansion link, and be provided with projection 6 in the position of the corresponding expansion link of blackboard panel; The blackboard panel area is identical with the frame internal area.During use, at ordinary times, without the both sides pull-up by blackboard panel, can be used as the plane blackboard and use; When if blackboard panel is reflective, when writing on the blackboard is read in impact, can hold the projection of blackboard panel, by the both sides pull-up of blackboard panel, form Curved surface blackboard; Blackboard panel can adopt thin aluminum sheet, plastic plate etc. to make, and on the surface of thin aluminum sheet, plastic plate, is brushed with the coating of black.
