The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Fig. 1 and 2 show an assembly operation teaching aid comprising: the structure comprises a bottom plate 100, two cross beams 200, a bulkhead plate 300, two stiffeners 400 and a short angle iron diagonal brace 500. The two cross members 200 are parallel to each other and are both perpendicularly fixed to the upper surface of the base plate 100. The bulkhead plate 300 is vertically fixed to the bottom plate 100 and the two cross beams 200, the bulkhead plate 300 is provided with two avoidance grooves 310, and the two cross beams 200 respectively pass through the two avoidance grooves 310. The two stiffening members 400 are fixed to the same side of the bulkhead plate 300 and extend in the vertical direction, and the two stiffening members 400 are fixed to the two cross beams 200, respectively. Two ends of the short angle iron diagonal brace 500 are respectively fixed on one side of the cross beam 200 and the bulkhead plate 300 far away from the two stiffening materials 400.

The connection relationship and the position relationship among the bottom plate 100, the two cross beams 200, the bulkhead plate 300, the two stiffeners 400, and the short angle iron diagonal braces 500 can be displayed more clearly by using the assembly operation teaching aid. In this embodiment, the two stiffening members 400 and the short angle iron bracing 500 are not located on the same side of the bulkhead plate 300, so that the connection strength between the short angle iron bracing 500 and the bulkhead plate 300 cannot be enhanced by the stiffening members 400, and the connection strength between the short angle iron bracing 500 and the bulkhead plate 300 is not high, which makes it difficult to meet the requirement of actual connection strength, and makes the bulkhead plate 300 prone to toppling.

In this embodiment, the position at which the stub brace 500 is connected to the bulkhead plate 300 is lower than the 2/3 height position of the bulkhead plate 300. The height of the above-mentioned position is not favorable for exerting the supporting effect of the short angle iron bracing 500 on the bulkhead plate 300.

In order to facilitate demonstration of the situation that the bulkhead 300 is toppled over after the supporting and connecting functions of the supporting members on the bulkhead 300 fail, in the embodiment, the assembly operation teaching aid further comprises a clamp diagonal brace 600, and two ends of the clamp diagonal brace 600 are respectively hinged to one side of the bulkhead 300, which is far away from the two stiffening members 400, and the other cross beam 200, which is far away from the short-angle iron diagonal brace 500. By utilizing the hinged relation among the clamp inclined strut 600, the cross beam 200 and the bulkhead plate 300, the inclination accident of the bulkhead plate 300 can be conveniently demonstrated after the supporting and connecting functions of the clamp inclined strut 600 are failed.

In order to facilitate the realization of the hinge relation between the clamp brace 600 and the cross beam 200 and the bulkhead plate 300, the assembly operation teaching aid further comprises two hinge assemblies 700, each hinge assembly 700 comprises a connecting assembly 710 and a hinge eye plate 720, the hinge eye plates 720 are fixed on the connecting assemblies 710, the two connecting assemblies 710 are respectively detachably connected to the bulkhead plate 300 and the cross beam 200, the two ends of the clamp brace 600 are respectively provided with a brace eye plate 610, and the two brace eye plates 610 are hinged to the two hinge eye plates 720. The hinge structure of the diagonal bracing eye plate 610 and the hinge eye plate 720 is simple, and is convenient to assemble and disassemble. The connecting member 710 includes a U-shaped member 711 having a notch formed therein, and a bolt 712, wherein one of opposite sides of the U-shaped member 711 has a threaded hole (not shown) formed therein, and the bolt 712 is coupled to the threaded hole. The U-shaped member 711, the threaded hole and the bolt 712 are matched to realize the detachable connection between the connecting assembly 710 and the bulkhead plate 300 and the cross beam 200.

In order to prevent the bolts 712 from loosening and avoid unstable connection between the connection assembly 710 and the bulkhead plate 300 and the cross beam 200, the connection assembly 710 further includes lock nuts 713, the lock nuts 713 are connected to the bolts 712, and nuts of the bolts 712 and the lock nuts 713 are respectively located on the same side of the threaded holes. In practical application, the notches of the two U-shaped members 711 are respectively sleeved on the cross beam 200 and the bulkhead plate 300, and the bolts 712 are tightened to enable the cross beam 200 and the bulkhead plate 300 to be respectively abutted against the inner walls of the two U-shaped members 711, so that the purpose of respectively fixing the two hinge assemblies 700 to the cross beam 200 and the bulkhead plate 300 is achieved. Then, the lock nut 713 is rotated to tighten the lock nut 713, thereby preventing the bolt 712 from being loosened.

In addition, the assembly operation teaching aid further comprises two hinges 800, the two hinges 800 are respectively located at the connecting positions of the two cross beams 200 and the bulkhead plate 300, and two ends of each hinge 800 are respectively connected with one cross beam 200 and one bulkhead plate 300. The two hinges 800 ensure that the bulkhead plate 300 is still connected with the two cross beams 200 when the bulkhead plate falls down, thereby avoiding safety accidents in the demonstration process.
