As a preferred scheme, a first guide inclined plane is arranged on the protrusion, a second guide inclined plane corresponding to the first guide inclined plane is arranged in the groove, when the upper metal box is overlapped on the lower metal box, the first guide inclined plane slides along the second guide inclined plane to insert the protrusion into the groove, and the first guide inclined plane is attached to the second guide inclined plane; the bulges are arranged on the corners of the lower metal box, and the grooves are formed in the corners of the bottom end of the upper metal box; the groove penetrates through the side face of the upper metal box outwards, the protrusion is inserted into the groove, and a gap is formed between the protrusion and the groove; the projections comprise transverse projections and longitudinal projections, and the grooves comprise transverse grooves and longitudinal grooves; when the upper metal box is superposed on the lower metal box, the transverse protrusion and the longitudinal protrusion are respectively inserted into the transverse groove and the longitudinal groove.

The implementation of the invention has the following beneficial effects:

1. after the lower part of the second side panel is inserted into the notch, the invention only needs to clamp the bulge into the first groove, the second side panel is clamped into the second groove under the action of gravity force, the second side panel can be locked at the vertical position, namely, the second side panel is vertically kept on the substrate without swinging, the second side panel is connected and fixed on the substrate without adopting a connecting piece, and when the second side panel is required to be folded on the upper surface of the substrate, only an upward pulling force needs to be exerted on the second side panel to lead the bulge to be separated from the second groove, then the second side panel swings towards the substrate, and the bulge can be separated from the first groove, thereby unlocking the vertical state of the second side panel, the invention has simple structure, convenient and quick use, and solves the problem that the fixed connection of the second side panel and the substrate needs to be realized by adopting a connecting element additionally in the existing metal box for keeping the second side panel vertical, and when the second side panel or the first side panel needs to be folded, the connecting element needs to be disassembled again, the operation and the disassembly are complex, the use is inconvenient, and the efficiency of loading and unloading goods and stacking and transporting empty boxes is seriously influenced.

2. The invention only needs to insert the lower part of the second side panel into the slot and sequentially insert the connecting piece into the long through hole and the slot hole from outside to inside, thereby realizing the purpose of quickly hinging and mounting the second side panel on the substrate; then, the first pin shaft is sleeved in the long groove, so that the first side panel can be hinged to the substrate, and the installation is simple, convenient and rapid.

3. According to the invention, the handle is manually held to push the lock rod to slide towards the through hole and press the swing hook, so that the hook part of the swing hook swings upwards to hook the top of the inner wall of the clamping groove on the second side panel corresponding to the first side panel, the first side panel and the second side panel of the metal box can be locked together, the operation is simple, quick and convenient, and the problems that when the adjacent first side panel and the second side panel need to be locked, firstly, the manual swing lock rod needs to be adjusted to adjust the position of the protrusion to enable the protrusion to be aligned with the clamping hole, then, the front end of the lock rod and the protrusion are pushed to extend into the clamping hole, and finally, the lock rod is manually swung in the reverse direction to enable the protrusion to clamp the inner wall of the clamping hole, so that the steps are complicated, the operation is complicated, and the use. And when the hook part hooks the inner wall of the clamping groove, the safety limiting device locks the lock rod, so that the lock rod cannot slide, the lock rod can be ensured to stably press the swing hook, the hook part of the swing hook can stably hook the top of the inner wall of the clamping groove, and the locking is stable, safe and reliable.

4. According to the invention, the first side panel and the second side panel of the metal box can be unlocked and separated only by manually holding the handle to push one end of the lock rod to slide towards the direction of withdrawing from the through hole and enabling the hook part of the swinging hook to be separated from the top of the inner wall of the clamping groove on the second side panel corresponding to the first side panel under the action of self gravity, so that the unlocking is simple, convenient and quick. The first side panel and the second side panel of metal box unblock and separation can be accomplished fast to whole unblock process only need control the horizontal slip direction of locking lever, and the labour saving and operation, low in labor strength.

5. When the unlocking is carried out, one end of the lock rod is pushed to slide towards the direction of withdrawing from the through hole only by manually holding the handle, the hook part of the swing hook can quickly swing towards the direction of the through hole under the dual functions of the elasticity of the first elastic piece and the self gravity, so that the hook part is separated from the top of the inner wall of the clamping groove on the second side panel corresponding to the first side panel, the first side panel and the second side panel of the metal box can be unlocked and separated, the unlocking is quicker and more convenient, and the situation that the first side panel and the second side panel of the metal box cannot be unlocked and separated due to the fact that the hook part cannot be separated from the clamping groove due to the self gravity of the swing hook is prevented.

6. When the locking rod needs to be pushed to slide, the elastic action of the second elastic piece needs to be overcome to reversely apply acting force on the limiting block, so that the limiting block swings reversely to disengage the protrusion from the first limiting clamping groove, and then the locking rod is unlocked and can slide under the action of the pushing force. The lock rod can be safely locked under the elastic action of the limiting block and the second elastic piece, and the lock rod can be pushed to slide after the lock rod is unlocked by swinging the limiting block during unlocking, so that the stability, the safety and the reliability of the lock rod for jacking and pressing the swing hook are ensured.
