DETAILED DESCRIPTION

[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] Example: See Figure 1-2In order to avoid damage to the balance when carrying it outside, and to solve the technical problems that the current fixed installation method of the balance is large in size, cannot be portable and mobile, and is not provided with a protective structure, and is easy to cause damage to the balance body during movement, an assembled teaching aid is provided, including a storage box 1, and an assembled demonstration structure is placed on the upper end of the storage box 1;

[0021] The assembled demonstration structure includes: two support frames 2, a connecting shaft 3, a connecting positioning assembly, a mounting sleeve 4, a fixing sleeve 5, two mounting rods 6 and a rotating observation assembly;

[0022] The two support frames 2 are placed on the upper end of the storage box 1, the connecting shaft 3 is movably embedded in the upper ends of the two support frames 2, the two ends of the connecting positioning assembly are respectively connected to the lower ends of the two support frames 2, the mounting sleeve 4 is movably sleeved on the upper end of the connecting shaft 3, the fixed sleeve 5 is fixedly installed on the upper end of the mounting sleeve 4, the two mounting rods 6 are respectively movably embedded on both sides of the fixed sleeve 5, and the rotating observation assembly is installed on one side of the mounting sleeve 4 and on the upper end of one of the support frames 2.

[0023] When assembling the balance teaching aid, the staff first opens the storage box 1 and takes out all the parts inside, then places the two support frames 2 on the upper end of the storage box 1, connects the upper ends of the two support frames 2 through the connecting shaft 3, and then connects and fixes the bottom ends of the two support frames 2 through the connecting positioning assembly. The two support frames 2 and the connecting positioning assembly form a triangle to stably connect the two support frames 2. Then, the two mounting rods 6 are successively embedded in both sides of the fixing sleeve 5, and the tray is hung on one side of the two mounting rods 6. Finally, the rotating observation assembly is installed on the mounting sleeve 4 and the upper end of the support frame 2 to complete the assembly operation. The weights and experimental materials can be placed on the upper ends of the two trays respectively, and the measurement work can be completed by observing the changes in the pointer of the rotating observation assembly. Through the above operations, the mounting rod 6 and the rotating observation assembly can be disassembled and stored independently, and the connecting positioning assembly can be removed at the same time, so that the two support frames 2 can be folded and stably stored in the storage box 1, which can effectively reduce the portability when going out and effectively avoid equipment damage.

[0024] Furthermore, the connection and positioning assembly comprises: two connection sleeves 7 and a connection rod 8;

[0025] The two connecting sleeves 7 are respectively installed on one side of the lower ends of the two supporting frames 2 , and the two ends of the connecting rod 8 are respectively movably embedded in the two connecting sleeves 7 .

[0026] When splicing the two supporting frames 2, the two ends of the connecting rod 8 are simultaneously embedded in the two connecting sleeves 7. The inner walls of the two connecting sleeves 7 and the outer walls of the two ends of the connecting rod 8 are processed with corresponding threads. Through the mutual engagement of the threads, the connecting rod 8 and the two connecting sleeves 7 are stably connected to ensure the supporting stability of the two supporting frames 2.

[0027] Furthermore, the rotating observation assembly includes: a plug-in sleeve 9, a mounting column 10, a scale plate 11, a pointer socket 12 and a pointer body 13;

When the weights on both sides are inconsistent, the pointer body 13 rotates with the mounting sleeve 4. By observing the position and direction of the scale plate 11 pointed to by the pointer body 13, the weights of the objects on both sides can be understood.
