Embodiment Construction

[0025] See Figure 1 to Figure 8 As shown, a device suitable for multimedia mathematics teaching includes a vertical T-shaped screw 1 connected to the blackboard wall in left and right symmetrical rotation. The inner ring of the bearing, the outer ring of the bearing is passed through the bearing seat detachably fixed on the wall of the blackboard, the bearing seat and the bearing play a role in supporting the T-shaped screw 1 and ensuring that the T-shaped screw 1 can rotate freely around its axis (Bearing and bearing seat are arranged as known technology, do not go into details here), described T-shaped screw rod 1 comprises first step shaft section 101, T-shaped stud 102, second step shaft section 103 and for The connecting section 104 that transmits the driving force, the first stepped shaft section 101 and the second stepped shaft section 103 are respectively used to connect the bearing and the bearing seat up and down, and also includes left and right symmetrical shafts ...

Abstract

The invention provides a device suitable for multimedia mathematical education. According to the scheme, the device comprises T-shaped threaded rods are bilaterally symmetrical and are rotatably connected with the two sides of a blackboard wall; two special-shaped nuts which pass through a T-shaped stud, of the T-shaped threaded rod, at intervals up and down are rotatably connected with two connecting rods; the other ends of the upper connecting rod and the lower connecting rod are rotatably connected with blackboards through pin shafts; a limiting structure for limiting each special-shaped nut to rotate is arranged between each special-shaped nut and a guide clamping groove vertically fixed in a wall body; each T-shaped threaded rod is connected with a driving device through meshed bevel gears; and a suction structure for limiting the blackboards from being freely separated from the blackboard wall and capable of moving up and down is arranged between the blackboard frame and the corresponding blackboard wall body. The device suitable for multimedia mathematical education solves the position conflict of the original fixed blackboard and a multimedia display curtain, enlarges the effective use area of the blackboard and the multimedia visible area, enlarges the view angle of the blackboard, improves the visuality of blackboard writing, guarantees continuous exhibition of mathematical education deducing process blackboard writing, and is favorable for carrying out mathematical education.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a device suitable for multimedia mathematics teaching. Background technique [0002] Mathematics, as one of the basic subjects, is a science that integrates rigor, logic, precision, creativity and imagination. In particular, college mathematics aims to cultivate students' logical thinking ability, spatial imagination ability, mathematical operation ability, and mathematical expression ability. , Enhancing the ability of mathematical modeling is the basis for learning the subsequent courses well. Multimedia technology has been widely used in mathematics teaching activities because of its pictures and texts, excellent audio and video, and both dynamic and static forms of expression. [0003] At present, due to its inherent teaching characteristics, university mathematics teaching is still dominated by the mode of "PPT teaching + blackboard writing + dictation". In the actual teaching process, th...
