DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the following preferred embodiments are referred to the drawings and are given, and the utility model is further explained in detail. However, it is explained that, many details listed in the specification are only for making the reader have a thorough understanding of one or more aspects of the utility model, and even without these specific details, the aspects of the utility model can be realized.

[0021] Please refer to Figures 1 to 4 , the utility model provides a kind of interactive teaching equipment for teaching, technical scheme is as follows:

[0022] Including projector 1, the rear side lower end of projector 1 is equipped with pivot 2, projector 1 is equipped with support 3 outward, and both ends of projector 1 pivot 2 are rotatably connected with support 3, the left and right ends of support 3 are arc triangular, and hollow in the middle, placing box 4 is equipped at the top of projector 1, and multiple projection cards 5 are placed in placing box 4, sliding groove 6 is equipped with at the front end of projector 1, and sliding groove 6 is left and right through slot, and projection card 5 can be inserted into sliding groove 6, adjusting assembly is equipped between projector 1 and support 3.

[0023] This non-computer projection teaching method can quickly adapt to different teaching environments. In some areas lacking electricity or network, it may be difficult to use traditional computer projectors for teaching; by using a drawing board, a chart or other physical teaching aids, teachers can adjust the teaching content at any time and flexibly respond to classroom situations; such interaction not only improves students' participation, but also enhances their understanding and memory;

[0024] Through the cooperation of the projector 1 and the projection card 5, the teacher can project the pre-designed coordinate system image onto the blackboard or whiteboard; this method not only ensures the accuracy and aesthetics of the coordinate system, but also saves the teacher's time in drawing on the blackboard, so that more energy can be concentrated on the teaching content and student interaction; in addition, the projection card 5 can be flexibly replaced according to different teaching needs, suitable for different mathematical topics such as linear functions, equation solving, geometric shapes, etc., or even teachers of other disciplines, can make projection cards 5 according to their own needs, which can reduce the situation of handling during class and improve convenience.

[0025] The adjusting assembly includes an arc-shaped rack 7 arranged on one side of the support 3, and the arc-shaped rack 7 is arranged on the arc-shaped side of the arc-shaped triangle of the support 3. The projector 1 is provided with a rotating rod 8 near one side of the arc-shaped rack 7, and the rotating rod 8 is provided with a gear 9 engaged with the arc-shaped rack 7. The end of the rotating rod 8 is provided with a rotating knob 10. A plurality of limiting grooves 11 are formed on the arc-shaped side of the other side of the support 3, and the plurality of limiting grooves 11 are arranged along the circumference of the arc-shaped side. A recess 12 is formed on one side of the projector 1 near the limiting groove 11. A limiting spring 13 is arranged in the recess 12, and the limiting spring 13 is provided with a limiting rod 14 matched with the limiting groove 11.

[0026] Due to individual differences, the height and habit of each teacher are different, and the height / angle needs to be adjusted when using the projector 1. When adjustment is needed, the rotating knob 10 is rotated, the rotating knob 10 drives the gear 9 to rotate through the rotating rod 8, and the rotating knob 10 drives the projector 1 to make a circular motion with the rotating shaft 2 as the center by the meshing action of the arc-shaped rack 7 on the support 3, that is, the angle of the projector 1 is adjusted, which is convenient for projecting onto the blackboard / whiteboard. During the adjustment process, the limiting rod 14 is in the same plane as the rotating shaft 2, so the limiting rod 14 moves with it, and the limiting rod 14 can cooperate with the plurality of limiting grooves 11. When the height and angle are adjusted to the appropriate position, the limiting rod 14 enters the corresponding limiting groove 11, providing support for the projector 1, avoiding the situation that the projector 1 cannot be adjusted in height / angle due to the downward rotation under the action of gravity, and improving the stability.
