Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, in particular to a screen fixing device for MOOC teaching. Background Art

[0002] MOOC, or Massive Open Online Courses, is a product of "Internet + Education" and a newly emerged online course development model. MOOC is known for large-scale online learning and is open. Learners of each course in MOOC can be all over the world, with huge capacity. MOOC allows learners of all ages, incomes and educational backgrounds to participate in a wide range of course learning, with strong independent choice. The learning content, learning time and learning progress can be completely controlled by the learners themselves, reflecting the teaching value orientation based on "learning". The screen of MOOC teaching generally needs to be fixed on a fixed device for use during teaching, but the existing screen fixing devices are not convenient to move, nor are they convenient to adjust the height and angle of the screen fixed thereon, which causes many inconveniences in teaching. Therefore, a technician in this field provides a screen fixing device for MOOC teaching to solve the problems raised in the above background technology. Summary of the invention

[0003] The purpose of the utility model is to provide a screen fixing device for MOOC teaching to solve the problems raised in the above-mentioned background technology.

[0011] Preferably: a limiting plate is jointly arranged at one end of the limiting spring 1 and the limiting spring 2 away from the I-shaped plate. The function of the limiting plate, limiting spring 1 and limiting spring 2 is to prevent the movable plate from falling off the I-shaped plate when sliding on the I-shaped plate. A movable plate is arranged on one side surface of the limiting plate.

[0012] Preferably, two groups of fixed guide blocks are symmetrically arranged at both ends of the surfaces of the two movable plates close to the I-shaped plates, and the positions of the two groups of fixed guide blocks correspond to the positions of the I-shaped plates.

[0013] Preferably, a slide groove is arranged on the surface of one side opposite to the two groups of fixed guide blocks, and both ends of the I-shaped plate are arranged in the slide groove.

[0014] Preferably: two clamping blocks are symmetrically arranged on the right side surfaces of the two movable plates, and protective pads are arranged on the opposite side surfaces of the two clamping blocks. The function of the protective pads is to protect the screen from friction damage when clamped between the two clamping blocks. A baffle is arranged on the right side surface of the clamping block. The function of the baffle is to protect the screen from falling off from between the two clamping blocks.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: by pulling the two moving plates in opposite directions, the moving plates can be moved up and down on the I-shaped plate through the slide grooves on the fixed guide blocks on the moving plates. The greater the distance between the two moving plates, the greater the pulling force of the limit spring one and the limit spring two. The functions of the limit plate, the limit spring one and the limit spring two are to prevent the moving plate from falling off the I-shaped plate when sliding on the I-shaped plate. Then the screen is placed between the two clamping blocks on the two moving plates. The screen is fixed between the two clamping blocks through the backward pulling force of the limit spring one and the limit spring two. The function of the baffle on the clamping block is to protect the screen from falling off from between the two clamping blocks to ensure the stability of the clamping effect. The function of the protective pad is to protect the screen in The two clamping blocks are not damaged by friction when clamped together. The screen can be rotated 360° by the rotating shaft on the rotating seat assembly, meeting the demand for screen angle. The sleeve rod can move up and down on the surface of the vertical pole to adjust the screen height. According to the required screen height, the fastening bolt is driven to rotate by turning the knob. The fastening bolt rotates to make one side surface of the suction cup close to the surface of the vertical pole inside the sleeve rod, thereby fixing the sleeve rod on the surface of the vertical pole, which solves the above-mentioned problem that the screen for MOOC teaching generally needs to be fixed on a fixed device for use during teaching. However, the existing screen fixing devices are not convenient to move, nor are they convenient to adjust the height and angle of the screen fixed thereon, which causes many inconveniences in teaching.

[0026] The working principle of the utility model is:

[0027] The utility model relates to a screen fixing device for MOOC teaching. In a specific use process, the device is first moved to a suitable teaching location, and then the two moving plates are pulled in opposite directions. Through the slide grooves on the fixed guide blocks on the moving plates, the moving plates can move up and down on the I-shaped plates. The farther the distance between the two moving plates is, the greater the pulling force of the limit spring 1 and the limit spring 2 is. The functions of the limit plate, the limit spring 1 and the limit spring 2 are to prevent the moving plate from falling off the I-shaped plates when sliding on the I-shaped plates. Then the screen is placed between the two clamping blocks on the two moving plates, and the screen is pulled back from the I-shaped plates by the pulling force of the limit spring 1 and the limit spring 2. The screen is fixed between the two clamping blocks. The function of the baffle on the clamping blocks is to protect the screen from falling off from between the two clamping blocks to ensure the stability of the clamping effect. The function of the protection pad is to protect the screen from friction damage when clamped between the two clamping blocks. The screen can be rotated 360° by the rotating shaft on the rotating seat assembly to meet the needs of the screen angle. The sleeve rod can move up and down on the surface of the vertical pole to adjust the height of the screen. According to the required screen height, the fastening bolt is driven to rotate by turning the knob. The fastening bolt rotates to make one side surface of the suction cup close to the surface of the vertical pole inside the sleeve rod, thereby fixing the sleeve rod on the surface of the vertical pole.
