Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] A multifunctional ruler system for teaching, including a support chassis, a first measuring ruler and a second measuring ruler. A rotating module is fixedly connected to the axis of the support chassis, and a support chassis is provided. The support chassis can be adsorbed on a blackboard, which is relatively firm , to solve the problem of inaccurate positioning and inconvenient when drawing a circle. The upper surface of the rotating module is sleeved with a bearing, a...

Abstract

The invention relates to the technical field of mathematic tools and discloses a multifunctional ruler system for teaching. The multifunctional ruler system for teaching comprises a supporting chassis, a first measuring ruler and a second measuring ruler. The axis position of the supporting chassis is fixedly connected with a rotary module. The upper surface of the rotary module is sleeved with abearing. The upper end of the rotary module is in threaded connection with a locking cap. One end of the front face of the first measuring ruler is provided with an insertion hole. The insertion holeis internally provided with a bearing in a sleeving manner. The side face of the end, far away from the insertion hole, of the first measuring ruler is provided with a tenon, one end of the first measuring ruler is in tenon-and-mortise connection with the second measuring ruler, and the side face of the second measuring ruler is provided with a mortise. The supporting chassis is arranged and can be attracted to a blackboard firmly, and the problem that during circle painting, positioning is inaccurate and inconvenient is solved; the bearings are arranged, and when the length of the teaching measuring rulers is relatively large, the measuring rulers can be rotated conveniently; and by means of the arrangement of the tenon and the mortise, the first measuring ruler and the second measuring ruler can be seamlessly connected, dismounting is also relatively convenient, and carrying of the teaching measuring rulers is facilitated.

Description

technical field [0001] The invention relates to the technical field of mathematical appliances, in particular to a multifunctional ruler system for teaching. Background technique [0002] Mathematics is a subject that uses symbolic language to study concepts such as quantity, structure, change, and spatial models. Mathematics, as an expression of human thinking, reflects people's aggressive will, meticulous logical reasoning, and pursuit of perfection. Different traditional schools can emphasize different aspects, but it is the interaction of these opposing forces and their combined efforts that constitute the vitality, usability and noble value of mathematical science; and in the current mathematics teaching During the activity, the teacher should often draw a series on the blackboard to facilitate the teaching. It is easier to draw the graphics drawn by the teacher, such as straight lines, squares, etc., but for circles, especially large-diameter It is difficult to draw a...
