[0024] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown: This embodiment provides a bending visualization device, including a mounting frame 100, on which a bending demonstration assembly 200 is provided. The bending demonstration assembly 200 includes a plurality of silicone strips 201 provided on a support frame and a plurality of demonstration plates 202 provided on the silicone strips 201 and fixed in position. The distance between two adjacent demonstration plates 202 is equal, and each demonstration plate 202 is penetrated by all silicone strips 201, so that the plurality of silicone strips 201 are arranged in parallel with each other. The demonstration plates 202 are mainly used to demonstrate the two internal forces when an object bends, namely bending moment and shear force; the silicone strips 201 are mainly used to connect and fix the position of the demonstration plates 202, and rely on their own elasticity to assist in the demonstration. The disk 202 can perform both rotation and movement. The present invention can cooperate with the support plate 300 through the bending demonstration component 200. When it is necessary to visualize the mechanical properties, the support plate 300 can be pulled out. At this time, the demonstration disk 202 will fall under the action of its own gravity, so that the positions of the two units will be relatively shifted, thereby visualizing the mechanical behavior of its components. This allows students to intuitively observe the internal forces acting on the components during bending and deformation, and can make up for the shortcomings of traditional teaching methods in terms of intuitiveness, dynamic demonstration and self-exploration, greatly improving learning efficiency, reducing the difficulty of understanding, and facilitating students to quickly and efficiently grasp the principles of component failure and the problems of mechanical performance analysis methods.

[0026] According to one embodiment of the present invention, Figure 1-4As shown, the axes of the plurality of silicone strips 201 are evenly distributed on the same circumference, the center of the circumference coincides with the center of the demonstration plate 202, and the diameter of the circumference is smaller than the diameter of the demonstration plate 202. Since the mass fraction of the internal density agent of the component is basically consistent and uniform, the purpose of this design is to ensure that the silicone strips 201 firmly support the demonstration plate 202, and to ensure that the pressure of the demonstration plate 202 on each silicone strip 201 is the same, so that the change of the mechanical properties of the component can be demonstrated more clearly and intuitively. The demonstration plate 202 is a circular sheet structure, and the demonstration plate 202 is made of acrylic plate or PVC sheet support, there are 8 silicone strips 201, the demonstration plate 202 and the silicone strip 201 are set together by glue. The utility model can adopt a demonstration plate 202 with a circular sheet structure, connect it in series through several deformable silicone strips 201, and support it through the support plate 300 straight beam division unit. On the one hand, it means that this is a straight beam structure. On the other hand, in order to prevent long-term deformation from causing irreversible damage to the teaching aids, each circular sheet structure is bonded to the silicone strip 201 by gluing, which greatly increases the tightness of its connection with the silicone strip 201.

[0027] According to another embodiment of the present invention, Figure 1 Figure 2 and Figure 4 As shown, a support assembly is provided on the mounting frame 100, and the support assembly is located below the demonstration plate 202, and is used to support the demonstration plate 202 when not in demonstration. The support assembly includes a slot 103 opened at the same height of the two brackets 102, and a support plate 300 is inserted into the slot 103. A handle 301 is provided at the end of one side of the support plate 300. The function of the support plate 300 is to support the demonstration plate 202 when the bending visualization device is not in use. The support plate 300 is located below the demonstration plate 202, and is used to support the demonstration plate 202 when not in demonstration. The bracket 102 is mainly used to support the silicone strip 2 01 and the demonstration plate 202 are fixedly supported. The function of the base 101 is mainly to support and stabilize the bending visualization device as a whole. The demonstration plates 202 at both ends are fixed together with the inner wall of the bracket 102 by bolts 203. The bolts 203 are four M5 bolts 203. The utility model can support and fix the position of the demonstration plate 202 thereon through the direct cooperation of the silicone strip 201 and can assist the demonstration plate 202 to rotate and move through its own elasticity, so that learners can see the internal force of the component when it is bent and deformed more clearly and intuitively, which is more intuitive.

[0028] According to another embodiment of the present invention, Figure 1 and Figure 3As shown, each bracket 102 is provided with a slot 103, and the support plate 300 is inserted into the slot 103. A handle 301 is provided at one end of the support plate 300. The handle 301 is an arc-shaped structure, and the axial length of the handle 301 is greater than the length of the slot 103. The utility model can facilitate the operation of the experimenter by setting the arc-shaped handle 301 at one end of the support plate 300. By setting the handle 301 larger than the length of the slot 103 of the base 101, the depth of the support plate 300 inserted into the slot 103 can be limited and blocked to a certain extent. More conveniently, the utility model allows the operator to grasp the arc-shaped handle 301 and align the end of the support plate 300 with the card slot 103 to pull and insert the support plate 300 to effectively support the demonstration disk 202, thereby preventing the rubber strip from being permanently bent and deformed due to the gravity pressure of the demonstration disk 202, thereby affecting the demonstration effect of the teaching aid. When in use, the support plate 300 is pulled out, and the demonstration disk 202 will fall under the action of gravity, producing a bending effect, which makes it easier for the experimenter to more clearly and intuitively observe the internal force inside the component when it is bent and deformed.

[0029] The use method of this utility model:

[0030] First of all, it should be made clear that the bending visualization device involved in the present invention is mainly used to visualize the internal forces of the bending deformation of materials in teaching experiments, so that students can quickly and efficiently grasp the principles of component failure and the mechanical performance analysis methods, and can enable students to intuitively observe the internal forces of the components when they are bent and deformed. It can make up for the shortcomings of traditional teaching methods in terms of intuitiveness, dynamic demonstration and self-exploration, greatly improve learning efficiency and reduce the difficulty of understanding. The present invention uses the method of using the bending visualization device as an example to explain its method of use in detail. When a bending visualization demonstration is required, the operator grasps the arc-shaped handle 301 and pulls the support plate 300 outward along the card slot 103. The demonstration disk 202 will fall under the action of gravity to produce a bending effect, which is convenient for the experimenter to more clearly and intuitively observe the internal forces of the components when they are bent and deformed. After the demonstration is completed After that, the operator grasps the arc-shaped handle 301 and inserts the support plate 300 along the card slot 103 to effectively support the demonstration disk 202, thereby preventing the rubber strip from being permanently bent and deformed due to the gravity pressure of the demonstration disk 202, thereby affecting the demonstration effect of the teaching aid. The utility model can cooperate with the function of the support plate 300 by bending the demonstration component 200. When it is necessary to visualize the mechanical properties, the support plate 300 can be pulled out. At this time, the demonstration disk 202 will fall under the action of its own gravity, so that the positions of the two units will be relatively displaced, thereby visualizing the mechanical behavior of its components, enabling students to intuitively observe the internal forces inside the components when they are bent and deformed, and can make up for the shortcomings of traditional teaching methods in terms of intuitiveness, dynamic demonstration and self-exploration, greatly improving learning efficiency, reducing the difficulty of understanding, and facilitating students to quickly and efficiently grasp the principles of component failure and the problems of mechanical performance analysis methods.
