[0048] Embodiment 4

[0049] See also Figure 1-Figure 11As shown, the present embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment. When it is necessary to store physical experiment equipment, the buckle 104 in the storage box body 1 is pulled upward, so that the buckle 104 cancels the clamping connection with the clamp head 105, and the second box body 102 can be opened from the top of the first box body 101, so that the physical experiment equipment can be stored in the first box body 101 and the second box body 102 respectively. When placing the experimental equipment in the first box body 101, it is necessary to first pull the lever 2045 inside the clamping member 204 in the display mechanism 2 backward. In the process of pulling the lever 2045, the lever 2045 will drive the plug block 2043 to slide backward through the slider 2044, so that the plug block 2043 cancels the connection with the support plate 2 02 is connected, and the support plate 202 can be propped up from the inside of the box body 101, which is convenient for storing physical experiment equipment in the box body 101. After storing the equipment, the support plate 202 is snapped onto the top of the box body 101 again. Since the front end of the plug block 2043 is processed into a wedge shape, it is only necessary to press the support plate 202 downward to make the support plate 202 and the plug block 2043 snap together again. When it is necessary to place the physical experiment equipment into the inside of the box body 2 102, the hanging ring 302 in the enclosure mechanism 3 is taken out from the inner side of the small hook 304, so that the small hook 304 cancels the hanging of the hanging ring 302, so that the blocking net 301 can be removed from the top of the box body 2 102, which is convenient for placing the physical experiment equipment into the inside of the box body 2 102 After storing the physical experiment equipment, the blocking net 301 is re-hook to the inside of the small hook 304 through the hanging ring 302, so as to enclose the physical experiment equipment stored in the second box 102. After the physical experiment equipment is stored in both the first box 101 and the second box 102, the second box 102 is buckled to the top of the first box 101 again, and the buckle 104 and the clamp head 105 cooperate with each other to clamp the first box 101 and the second box 102 that are buckled together to prevent them from being scattered during transportation. After the storage box main body 1 and the physical experiment equipment are transported to the place where they are needed, that is, inside the classroom or laboratory, if it is necessary to demonstrate the physical experiment process to students, first put the storage box main body 101 and the second box 102 together. The physical experiment equipment in box 102 is taken out, and then the unfolded box 1 101 and box 2 102 are erected, and the display mechanism 2 is propped up, so that the support plate 202 forms a small platform at the front end of the erected box 1 101, and the box 2 102 is located at the top of the box 1 101.

At the same time, due to the weight of box 1 101, box 2 102, display mechanism 2 and the experimental equipment needed to be placed on the top of the support plate 202 for physical experiment demonstration, if the total weight is too high,This may cause box body 101 and box body 2 102 to slip off the front end of the blackboard or the podium. At this time, after box body 101 and box body 2 102 are adsorbed to the front end of the blackboard or the podium, the button 4068 inside the retracting member 406 in the auxiliary fixing mechanism 4 is pressed inwardly. By pressing the button 4068, the insertion rod 4067 can be driven to slide into the inside of the sleeve 4061, thereby driving the second clamping block 4066 to retract into the inside of the winding roller 4063, thereby canceling the first clamping block 4065 and the second clamping block. The clamping connection between the blocks 4066 allows the winding roller 4063 to rotate on the inner side of the shaft disk 4062, so that the large hook 404 can be pulled upward. In the process of pulling the large hook 404, the large hook 404 will drive the connecting rope 4064 to move together. After the large hook 404 is hung on the front outer edge of the blackboard or the podium, the pressing of the button 4068 is cancelled. The button 4068 can be pushed outward by the work of the second spring 4069, so that the second clamping block 4066 can be reset by the insertion rod 4067. , so that the second clamping block 4066 is clamped to the inner side of the first clamping block 4065 again, thereby clamping the winding roller 4063, preventing the connecting rope 4064 from continuing to be released from the outer wall of the winding roller 4063, and through the cooperation between the large hook 404 and the connecting rope 4064, the box body 102 can be lifted, thereby assisting the box body 101 and the box body 102 to be adsorbed to the front end of the blackboard or the podium, preventing the box body 101 and the box body 102 from slipping off the front end of the blackboard or the podium during the experiment, and when the connecting rope 406 needs to be adjusted, the box body 101 and the box body 102 can be lifted. When winding the connecting rope 4064, first remove the large hook 404 hung on the outer edge of the top of the blackboard or the podium, and then press the button 4068 to cancel the engagement between the second clamping block 4066 and the first clamping block 4065, so that the winding roller 4063 can rotate on the inner side of the shaft disc 4062 again, and the winding roller 4063 can rotate in the opposite direction by working the winding spring processed between the shaft disc 4062 and the winding roller 4063, so that the connecting rope 4064 can be rewound to the outer wall of the winding roller 4063.
