[0039] The protection box 1 is provided with a reserved opening 13 and a ventilation hole 14 .

[0040] The working principle of this utility model:

[0041] During the use of the present protective assembly, the teaching case can be placed on the base 3, the bottom of the teaching case can be inserted into the groove 31, and the bottom of the teaching case can be limited by the side walls around the groove 31, and then the cover plate 4 connected to the support plate 32 can be rotated to insert the top of the teaching case into the storage groove provided at the bottom of the cover plate 4, thereby achieving the purpose of limiting the top of the teaching case by the side walls around the storage groove, and then the base 3 and the teaching case placed on the box cover 2 are pushed toward the protective box 1, and the base 3 and the teaching case slide along the slide rail 21 toward the protective box 1 under the guidance of the slider 33 and the slide rail 21, and the slide rail 2 1 is aligned with the guide rail 12, so that the slider 33 can slide smoothly onto the guide rail 12 during the sliding process on the slide rail 21, thereby sliding the base 3 and the teaching machine box into the protection box 1. At the same time, as the support plate 32 approaches the inner wall of the protection box 1, the expansion airbag 5 fixedly connected to the support plate 32 will abut against the inner wall of the protection box 1, thereby squeezing the expansion airbag 5, so that the gas in the expansion airbag 5 is filled into the contraction airbag through the connecting pipe 51. The contraction airbag is expanded by the gas filled, and then the sliding plate 61 is pushed away from the cover plate 4 until the sliding plate 61 abuts against the top inner wall of the protection box 1, and then the box cover 2 is turned. The box cover 2 is automatically closed. After the box cover 2 is closed, the slide rail 21 fixedly connected thereto will abut against the outer side walls of the base 3 and the cover plate 4, thereby applying a stable thrust to the base 3 and the cover plate 4, and driving the lock buckle 23 to rotate by rotating the lock head 22, so that the lock buckle 23 and the side wall of the protection box 1 are misaligned and fit, thereby achieving the purpose of limiting and locking the box cover 2. After the locking is completed, the base 3 and the cover plate 4 are in the protection box 1, and their bottoms are limited by the mutual cooperation of the slider 33 and the guide rail 12 and cannot move forward and backward. The side wall close to the box cover 2 is abutted against the surface of the slide rail 21, and one side of the support plate 32 is abutted against the inner wall of the protection box 1 through the inflatable airbag 5, and the top plate is pressed against the inner wall of the protection box 1 by the contraction of the airbag. The airbag and the sliding plate 61 abut against the inner wall at the top of the protection box 1, thereby providing position protection for the teaching case limited within the base 3 and the cover plate 4. When the protection box 1 falls over, the inflatable airbag 5 and the deflated airbag can flexibly damp the base 3 and the teaching case. When the protection box 1 is hit, it can absorb the impact force by partially deforming its part, and the gap between the teaching case and the inner wall of the protection box 1 can prevent the deformation of the protection box 1 from squeezing the teaching case. At the same time, the reserved opening 13 on the protection box 1 can facilitate the wiring and control of the teaching case during use, and the ventilation holes 14 can facilitate the heat dissipation of electronic accessories in the teaching case during operation.

[0042] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
