Embodiment 1

[0063] Such as figure 1 and figure 2 As shown, this embodiment proposes a projection device for teaching and its use method, including a guide box 1, the tops of both sides of the guide box 1 are provided with fixing parts 2 for fixing the guide box 1 to the top of the room, and the guide box 1 Limiting parts 3 are arranged on both sides of the bottom end, and a storage mechanism 4 is arranged between the two limiting parts 3. The storage mechanism 4 is connected to a projector 5, and the top of the storage mechanism 4 is provided with a connecting mechanism 6. The top is also provided with the first limit mechanism 7 of the limit connection mechanism 6, the second limit mechanism 8 of the limit projector 5 is arranged on the first limit mechanism 7, and the side of the storage mechanism 4 is provided with a heat dissipation mechanism 9, One side of the storage mechanism 4 is also provided with a dust-proof mechanism 10 that cooperates with the heat dissipation mechanism 9. ...

Embodiment 2

[0065] The scheme in embodiment 1 is further introduced below in combination with specific working methods, see the following description for details:

[0066] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 11 As shown, as a preferred embodiment, on the basis of the above method, further, the fixing member 2 is a fixing block fixedly installed on the guide box 1, and the fixing block is provided with a perforation, and the external bolts are passed through the perforation and connected to the top of the room. Threaded connection makes the fixed block fixed, and then guide box 1 is fixed, and stopper 3 comprises stop bar 301, and the top of stop bar 301 is fixedly installed in the middle part of guide box 1 bottom both sides, and the bottom of stop bar 301 The end is fixed with a limit plate 302, and the opposite sides of the two limit plates 302 are provided with a first limit groove, and one side of the limit rod 301 is provided with a second limit groove...

Embodiment 3

[0081] The schemes in Embodiment 1 and Embodiment 2 are further introduced below in conjunction with specific working methods, see the following description for details:

[0082]Specifically, when the teaching projection device and its use method are working / using: the guide box 1 can be fixed on the top of the room through the fixing block and the external bolts, and the second connecting rope 1302 can be bypassed and installed on the wall of the room. Several external pulleys are connected with the output shaft of the external stepping motor installed in the corner of the room, the external stepping motor is connected with the external controller, the projector 5 is inserted between the two reeds 405, and the projector 5 is connected to the rubber layer 901 are in contact with each other, under the action of reed 405, projector 5 can be calibrated so that it is placed in the middle of storage box 402, and the positioning rod 803 is rotated through the hinge so that positionin...

Abstract

The invention provides a teaching projection device and a use method thereof, the teaching projection device comprises a guide box, the tops of the two sides of the guide box are both provided with fixing parts used for fixing the guide box at the indoor top end, the two sides of the bottom end of the guide box are both provided with limiting parts, and a storage mechanism is arranged between the two limiting parts. Through the arrangement of the guide mechanism, the plurality of external pulleys for installing the guide mechanism on the indoor wall and the external stepping motor installed at the indoor wall corner, when the projector needs to be maintained, the external stepping motor is controlled to work, so that the storage mechanism drives the projector to move downwards, and the storage mechanism moves to the lowermost part. By operating the second limiting mechanism, the projector can be conveniently taken out for maintenance, personnel need to climb to operate during primary installation, personnel do not need to climb to maintain the projector later, maintenance of the projector is facilitated, and the safety of maintenance personnel is improved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a teaching projection device and a method for using the same. Background technique [0002] In the process of teaching, projectors are often used, and projectors are generally installed in high places in the classroom. Therefore, when installing or maintaining projectors, people need to go up to handle them, which is not only inconvenient for projector installation or maintenance, but also And there are security risks. [0003] Therefore, we make improvements to this, and propose a projection device for teaching and a method for using the same. Contents of the invention [0004] The purpose of the present invention is to solve: in the process of teaching, projectors are often used, but generally projectors are installed in high places in the classroom, so when installing or maintaining the projectors, it is necessary for personnel to climb up to handle, which is not onl...
