[0006] The effect achieved by the above components is: when it is necessary to use a geometric model to demonstrate to students, first pull the transparent display glass that needs to display the model, and the transparent display glass moves with the cylinder and the circular plate. When the circular plate moves to the position of the fixed ring, the fixed ring squeezes the inclined surface of the card plate, and the card plate moves toward the inside of the groove, and the spring contracts. When the card plate moves over the fixed ring, under the action of the spring reset elastic force, the card plate moves out of the groove. At this time, the card plate and the circular plate clamp the fixed ring, achieving the effect of limiting the transparent display glass. At this time, the students watch the teaching model inside through the transparent display glass. When the students do not need to watch the geometric model, the teacher moves the card plate, and the card plate moves toward the inside of the groove. After the card plate is completely entered into the groove, under the action of the gravity of the circular plate and the cylinder, the transparent display glass enters the reserved hole of the display box to hide the transparent display glass. The display device achieves the effect of facilitating teachers to display different models to students at the same time. When it is necessary to watch the model at different angles, the teacher can adjust the angle of the model in the transparent display glass by rotating the transparent display glass, thereby improving the geometric model demonstration effect.

[0010] The effect achieved by the above components is: by setting the telescopic rod, the effect of limiting the moving direction of the card plate is achieved, thereby preventing the card plate from rotating and improving the stability of the card plate movement.

[0011] Preferably, one end of the clamping plate away from the spring is fixedly connected to two mutually symmetrical rectangular plates, and one side of the two rectangular plates close to each other is rotatably connected to the same rotating rod.

[0012] The effect achieved by the above components is: when the card plate moves in the inner wall of the fixed ring, the rotating rod and the inner wall of the fixed ring rotate, thereby reducing the friction between the card plate and the inner wall of the fixed ring, bringing convenience to the teacher.

[0013] Preferably, auxiliary devices are provided on both sides of the display box, and the auxiliary devices include two pads, which are respectively fixedly connected to the two sides of the display box, and the surfaces of the pads are threadedly connected with screws, and one end of the screws is provided with a bottom plate.

[0014] The effect achieved by the above components is: when the height of the display box needs to be adjusted, first rotate the screw, and the screw will move the bottom plate toward the table top, and finally the bottom plate will rest on the table top to support the display box. The auxiliary device can facilitate teachers to adjust the height of the display box, making it convenient for more students to view the geometric models in the transparent display glass, thereby improving the practicality of the display box.

[0015] Preferably, one end of the bottom plate away from the screw rod is fixedly connected with a rubber pad, and the size of the rubber pad is matched with the size of the bottom plate.

[0016] The effect achieved by the above components is: the friction between the bottom plate and the table top is increased by arranging the rubber pad, thereby preventing the bottom plate and the table top from sliding.

[0017] Preferably, a bearing is provided at one end of the screw rod, the outer ring of the bearing is fixedly connected to the base plate, and the inner ring of the bearing is fixedly connected to the screw rod.

[0018] The effects achieved by the above components are: the stability of the screw rotation is improved by setting the bearing, and the screw is prevented from shaking.

[0019] Preferably, a limit rod is slidably provided on the surface of the pad, and one end of the limit rod is fixedly connected to the bottom plate.

[0020] The effect achieved by the above components is: by setting the limit rod, the moving direction of the bottom plate is limited to prevent the bottom plate from rotating.

[0021] In summary, the beneficial effects of the utility model are:

[0022] When it is necessary to use a geometric model to demonstrate to students, first pull the transparent display glass that needs to display the model, and the transparent display glass moves with the cylinder and the circular plate. When the circular plate moves to the position of the fixed ring, the fixed ring squeezes the inclined surface of the card plate, and the card plate moves toward the inside of the groove, and the spring contracts. When the card plate moves over the fixed ring, the card plate moves out of the groove under the action of the spring reset elastic force. At this time, the card plate and the circular plate clamp the fixed ring, achieving the effect of limiting the transparent display glass. At this time, the students watch the teaching model inside through the transparent display glass. When the students do not need to watch the geometric model, the teacher moves the card plate, and the card plate moves toward the inside of the groove. After the card plate is completely entered into the groove, under the action of the gravity of the circular plate and the cylinder, the transparent display glass enters the reserved hole of the display box to hide the transparent display glass. The display device achieves the effect of facilitating teachers to display different models to students at the same time. When it is necessary to watch the model at different angles, the teacher can adjust the angle of the model in the transparent display glass by rotating the transparent display glass, thereby improving the geometric model demonstration effect.

DETAILED DESCRIPTION

[0029] Reference Figure 1-5 As shown, this embodiment discloses a multifunctional three-dimensional geometric demonstration model, including a display box 1, a plurality of reserved holes 2 are evenly opened on the upper surface of the display box 1, the display box 1 is provided with a display device 3 by means of the reserved holes 2, and auxiliary devices 4 are provided on both sides of the display box 1.

[0030] Reference Figure 1-5As shown, the display device 3 includes a plurality of cylinders 31, and the plurality of cylinders 31 are respectively slidably inserted into the interior of the plurality of reserved holes 2. A circular plate 33 is fixedly connected to the bottom of the cylinder 31, and the size of the circular plate 33 is adapted to the size of the reserved hole 2. The display box 1 is fixedly connected to a fixing ring 34 by means of the reserved hole 2, and the inner wall size of the fixing ring 34 is adapted to the size of the cylinder 31. A transparent display glass 32 is fixedly connected to the upper surface of the cylinder 31, and different geometric models are respectively inlaid in the interior of the plurality of transparent display glasses 32. Two mutually symmetrical grooves 35 are provided on the arc surface of the cylinder 31, and a spring 36 is fixedly connected to the cylinder 31 by means of the groove 35, and a clamping plate 37 is fixedly connected to one end of the spring 36. When it is necessary to use a geometric model to demonstrate to students, first pull the transparent display glass 32 on which the model needs to be displayed, and the transparent display glass 32 moves with the cylinder 31 and the circular plate 33. When the circular plate 33 moves to the position of the fixing ring 34, the fixing ring 34 squeezes the inclined surface of the card plate 37, and the card plate 37 moves toward the inside of the groove 35, and the spring 36 contracts. When the card plate 37 moves past the fixing ring 34, the card plate 37 moves out of the groove 35 under the action of the restoring elastic force of the spring 36. At this time, the card plate 37 and the circular plate 33 clamp the fixing ring 34, thereby achieving the effect of limiting the transparent display glass 32. At this time, students can use the transparent display glass 32 to control the inside of the card plate 37. The teaching model is viewed. When the students do not need to view the geometric model, the teacher moves the card board 37, and the card board 37 moves toward the inside of the groove 35. After the card board 37 completely enters the groove 35, under the action of the gravity of the circular plate 33 and the cylinder 31, the transparent display glass 32 enters the reserved hole 2 of the display box 1 to hide the transparent display glass 32. The display device 3 is used to facilitate the teacher to display different models to the students at the same time. When the model needs to be viewed from different angles, the teacher can adjust the angle of the model in the transparent display glass 32 by rotating the transparent display glass 32, thereby improving the geometric model demonstration effect.

[0031] Reference Figure 1-5As shown, the upper surface of the transparent display glass 32 is fixedly connected with a moving plate 311, and the top of the moving plate 311 is fixedly connected with a pull rod 312 by means of a rectangular groove. By setting the pull rod 312, the effect of facilitating the teacher to move the transparent display glass 32 is achieved, which brings convenience to the teacher. The inner wall of the groove 35 is fixedly connected with a telescopic rod 310, and one end of the telescopic rod 310 is fixedly connected with the card plate 37. By setting the telescopic rod 310, the effect of limiting the moving direction of the card plate 37 is achieved, so that the card plate 37 is prevented from rotating, and the stability of the movement of the card plate 37 is improved. One end of the card plate 37 away from the spring 36 is fixedly connected with two mutually symmetrical rectangular plates 38, and the side of the two rectangular plates 38 close to each other is rotatably connected with the same rotating rod 39. When the card plate 37 moves in the inner wall of the fixed ring 34, the rotating rod 39 and the inner wall of the fixed ring 34 rotate, thereby reducing the friction between the card plate 37 and the inner wall of the fixed ring 34, which brings convenience to the teacher.

[0032] Reference Figure 1-5 As shown, the auxiliary device 4 includes two pads 41, which are fixedly connected to the two sides of the display box 1, and the surface of the pads 41 is threadedly connected with a screw rod 42, and one end of the screw rod 42 is provided with a bottom plate 43. When the height of the display box 1 needs to be adjusted, the screw rod 42 is first rotated, and the screw rod 42 moves the bottom plate 43 toward the desktop, and finally the bottom plate 43 rests on the desktop to support the display box 1. The auxiliary device 4 is used to facilitate the teacher to adjust the height of the display box 1, and more students can watch the geometric model in the transparent display glass 32, thereby improving the practicality of the display box 1.

[0033] Reference Figure 1-5 As shown, a rubber pad 45 is fixedly connected to one end of the bottom plate 43 away from the screw rod 42, and the size of the rubber pad 45 is adapted to the size of the bottom plate 43. The rubber pad 45 is provided to increase the friction between the bottom plate 43 and the desktop, thereby preventing the bottom plate 43 and the desktop from sliding. A bearing 46 is provided at one end of the screw rod 42, and the outer ring of the bearing 46 is fixedly connected to the bottom plate 43, and the inner ring of the bearing 46 is fixedly connected to the screw rod 42. The bearing 46 is provided to improve the stability of the rotation of the screw rod 42, thereby preventing the screw rod 42 from shaking. A limit rod 44 is slidably provided on the surface of the pad 41, and one end of the limit rod 44 is fixedly connected to the bottom plate 43. The limit rod 44 is provided to limit the moving direction of the bottom plate 43, thereby preventing the bottom plate 43 from rotating.

[0034] Working principle: When it is necessary to use a geometric model to demonstrate to students, first pull the pull rod 312 above the transparent display glass 32 where the model needs to be displayed. The pull rod 312 moves with the transparent display glass 32, the cylinder 31 and the circular plate 33. When the circular plate 33 moves to the position of the fixed ring 34, the fixed ring 34 squeezes the inclined surface of the card plate 37, and the card plate 37 moves toward the inside of the groove 35. The telescopic rod 310 and the spring 36 shrink. At this time, the rotating rod 39 on the card plate 37 and the inner wall of the fixed ring 34 rotate, thereby reducing the friction between the card plate 37 and the inner wall of the fixed ring 34. When the card plate 37 moves over the fixed ring 34, the card plate 37 moves out of the groove 35 under the action of the restoring elastic force of the spring 36. At this time, the card plate 37 and the circular plate 33 clamp the fixed ring 34. The transparent display glass 32 is limited in position. At this time, students view the teaching model inside the transparent display glass 32. When students do not need to view the geometric model, the teacher moves the card plate 37, and the card plate 37 moves toward the inside of the groove 35. After the card plate 37 completely enters the groove 35, under the action of the gravity of the circular plate 33 and the cylinder 31, the transparent display glass 32 enters the reserved hole 2 of the display box 1 to hide the transparent display glass 32. The display device 3 is used to facilitate teachers to display different models to students at the same time. When the model needs to be viewed at different angles, the teacher can adjust the angle of the model in the transparent display glass 32 by rotating the transparent display glass 32, thereby improving the geometric model demonstration effect.

[0035] When the height of the display box 1 needs to be adjusted, the screw 42 is first rotated. The bearing 46 at one end of the screw 42 improves the rotation stability of the screw 42. The screw 42 moves toward the desktop with the bottom plate 43. Finally, the bottom plate 43 is against the desktop with the help of the rubber pad 45 to support the display box 1. The auxiliary device 4 is used to facilitate the teacher to adjust the height of the display box 1, which makes it convenient for more students to view the geometric model in the transparent display glass 32, thereby improving the practicality of the display box 1.
