DETAILED DESCRIPTION

[0022] See also Figure 1-4 A display stand for painting teaching includes a mounting frame 1, a base 3 is arranged below the mounting frame 1, two sets of universal wheels 4 are fixedly installed on the bottom surface of the base 3, and the installation of the base 3 and the universal wheels 4 makes it convenient for teachers to move the device, thereby increasing the convenience of moving the device.

[0023] A switching mechanism 2 is provided above the mounting frame 1; the switching mechanism 2 includes a display stand frame 201, the back of the display stand frame 201 is fixedly connected to the front of the mounting frame 1, and two groups of cylinders 5 are fixedly installed on the upper surface of the base 3, and the telescopic end of each cylinder 5 is fixedly connected to the bottom surface of the mounting frame 1. The power provided by the cylinder 5 is used to drive the mounting frame 1 to move up and down, so as to facilitate the teacher to adjust the height of the mounting frame 1, and try to avoid students at the back of the classroom from being blocked from viewing the works, thereby facilitating students to view.

[0024] The exhibition stand frame 201 is internally rotatably connected with a ball screw 202, and a rotating motor 203 is arranged on the left side of the exhibition stand frame 201. The output end of the power of the rotating motor 203 passes through the exhibition stand frame 201 and is fixedly connected to the left end of the ball screw 202. A support platform 6 is fixedly installed on the bottom surface of the rotating motor 203, and the right side surface of the support platform 6 is fixedly connected to the left side surface of the exhibition stand frame 201. The installation of the support platform 6 plays a role in fixing the rotating motor 203, thereby minimizing the rotation of the rotating motor 203 during operation, thereby ensuring the stability of the rotation of the rotating motor 203.

[0025] The outer surface of the ball screw 202 is threadedly connected to the moving frame 204, and two hydraulic rods 205 are fixedly installed on the inner wall of the moving frame 204. The telescopic ends of the two hydraulic rods 205 are jointly fixedly installed with a connecting plate 206. The inner wall of the exhibition stand frame 201 is fixedly installed with a sliding rod 7, and the sliding rod 7 is slidably connected to the inside of the moving frame 204. The installation of the sliding rod 7 plays a role in limiting the moving trajectory of the moving frame 204, thereby minimizing the phenomenon that the moving frame 204 deviates from the moving trajectory during rotation, thereby ensuring the stability of the rotation of the moving frame 204.

[0026] A suction cup 207 is fixedly installed on the back of the connecting plate 206, and an air pump 208 is fixedly installed on the front of the connecting plate 206. Four groups of electric push rods 8 are fixedly installed on the inner wall of the exhibition stand frame 201. A rubber pad 9 is fixedly installed on the telescopic end of each electric push rod 8. There are two electric push rods 8 in each group. The power provided by the electric push rod 8 drives the rubber pad 9 to move to the side away from the electric push rod 8, so that the rubber pad 9 contacts the works placed inside the exhibition stand frame 201, thereby playing a role of pressing and fixing the works, trying to avoid the work from moving on its own, and thus ensuring the stability of the work.

[0027] The input end of the air pump 208 power is fixedly connected to a delivery pipe 209, and the end of the delivery pipe 209 away from the air pump 208 passes through the connecting plate 206 and extends to the inside of the suction cup 207. A battery 10 is fixedly installed on the upper surface of the base 3. The battery 10 is electrically connected to the rotating motor 203, the hydraulic rod 205, the air pump 208, the cylinder 5 and the electric push rod 8 through wires. The installation of the battery 10 can provide electrical energy to the electrical equipment of the device, so that the device does not need to be limited by the length of the wires, further increasing the practicality of the device.

[0028] The working principle of the utility model is as follows: when in use, the teacher first moves the device to the position where the works are displayed, and then the teacher first overlaps multiple works and places them on the exhibition stand frame 201, and uses the power provided by the electric push rod 8 to drive the rubber pad 9 to move to the side away from the electric push rod 8, so that the rubber pad 9 presses and fixes the works, thereby ensuring the stability of the works. Then the teacher turns on the cylinder 5 through the external remote control device, and uses the power provided by the cylinder 5 to drive the mounting frame 1 to move upward, so that it is convenient for the teacher to adjust the exhibition stand frame 201 to a suitable height, and then the teacher displays and teaches the works. When the teacher needs to switch the works, the teacher turns on the electric push rod 8 and the rotating motor 203 through the external remote control device, and uses the power provided by the electric push rod 8 to drive the rubber pad 9 to move to the side close to the electric push rod 8, thereby releasing the fixation of the works, and uses the power provided by the rotating motor 203 to drive the ball screw 202 to rotate, so that the ball screw 202 The movable frame 204 is driven to move to the left, so that the suction cup 207 corresponds to the work to be switched, and then the hydraulic rod 205 and the air pump 208 are opened, and the power provided by the hydraulic rod 205 is used to drive the connecting plate 206 to move to the side away from the movable frame 204, so that the suction cup 207 contacts the work, and the power provided by the air pump 208 is used to discharge the air between the suction cup 207 and the work, so that the work to be replaced is adsorbed on the suction cup 207, and then the power provided by the rotating motor 203 is used to drive the ball screw 202 to rotate in the opposite direction, so that the work to be switched is moved to the right side of the exhibition stand frame 201, thereby exposing the work below, and at the same time, the work moved to the right side is pressed on the exhibition stand frame 201 under the action of the hydraulic rod 205, and then the air pump 208 is used to release the adsorption effect on the work, and at the same time, the power provided by the electric push rod 8 drives the rubber pad 9 to continue to press and fix the work, thereby achieving the purpose of automatically switching the work by the device.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
