Embodiment 1

[0023] A rotating blackboard such as figure 1 and figure 2 As shown, it includes an outer frame 1 , a fixing part 2 arranged in the outer frame 1 and four fixing rods 3 extending outward from the fixing part 2 and fixed to the outer frame 1 . It also includes a rotating bracket 4. The rotating bracket 4 includes a rotating shaft part 41 and four telescopic struts 42 arranged on the rotating shaft part 41 and extending outward. The rotating shaft part 41 is sleeved on the fixed part 2 and can rotate relative to the fixed part 2. . A first driver is also included, the output end of the first driver is connected with the rotating shaft part 41 and is used to drive the rotating shaft part 41 to rotate. The inner periphery of the outer frame 1 is provided with a first track and a second track distributed along the circumferential direction, and the first track and the second track are arranged in parallel. Two first blackboards 51 are arranged in the first track, two second bla...

Embodiment 2

[0029] As an improvement of Example 1, such as Figure 3-Figure 5 As shown, in the present embodiment, it also includes a scrubbing bracket 6, the scrubbing bracket 6 is fixed with the fixing part 2, and is positioned in front of the front of the first blackboard 51 and the second blackboard 52, wherein the first blackboard 51 and the second blackboard 52 The side used for writing is the front side.

[0030] Such as Figure 5 As shown, the scrubbing bracket 6 includes a vertical bar 61 extending along the board surface of the blackboard, and also includes two cross bars 62 respectively fixed at both ends of the vertical bar 61 and extending along the direction perpendicular to the board surface of the blackboard. One of the cross bars 62 is fixed to the fixing part 2 , and the other one extends out of the outer frame 1 . On the opposite inner sides of the two cross bars 62, there are sliding grooves extending along the direction perpendicular to the board surface of the blac...

Abstract

A rotation type blackboard comprises an outer frame, a fixing part and a plurality of fixing rods, wherein the fixing rods extend outwards from the fixing part and are fixed with the outer frame. The rotation type blackboard further comprises a rotation support. The rotation support comprises a rotating shaft part and four telescopic supporting rods which are arranged on the rotating shaft part and extend outwards. The fixing part is sleeved with the rotating shaft part. The rotation type blackboard further comprises a first driver. The first driver is connected with the rotating shaft part and used for driving the rotating shaft part to rotate. A first track and a second track are distributed on the inner circumference of the outer frame in the circumferential direction. Two first blackboard bodies are arranged in the first track. Two second blackboard bodies are arranged in the second track. The first blackboard bodies and the second blackboard bodies are hinged to the telescopic supporting rods respectively and are arranged in the rotating circumferential direction of the telescopic supporting rods at intervals. The first blackboard bodies can slide along the first track, and the second blackboard bodies can slide along the second track. According to the rotation type blackboard, the first blackboard bodies and the second blackboard bodies can be rotated to any position within the range of the outer frame, accordingly, students can watch the blackboard conveniently, and the teaching quality of teachers is improved.

Description

technical field [0001] The application relates to the technical field of blackboards, in particular to a rotary blackboard. Background technique [0002] The blackboard is a flat board that can be repeatedly written and used for teaching. It is the memory of many people when they were studying. In the prior art, blackboards are divided into fixed type and movable type. Fixed blackboards are common in primary and middle school classrooms in small cities. This kind of blackboard cannot be moved on the wall, and it is easy for students sitting on the other side to see the words on the blackboard, which is not convenient for students to watch. Movable blackboards are widely used in university classrooms, but these fixed mobile blackboards can only move up and down or left and right, which is still inconvenient for students to watch and also affects teachers' lectures. Moreover, the current blackboard does not have an automatic scrubbing function, which increases the workload...
