[0031] In this embodiment, the left outer upper limit edge 55 and the left inner upper limit edge 57 are arranged in a V-shape with the right outer upper limit edge 56 and the right inner upper limit edge 58 on both sides of the locking rod 52. Correspondingly, the left lower limit edge 47 and the right lower limit edge 48 are also arranged in a V-shape. With this structure, the left and right positions of the locking seat assembly 5 are defined by the locking buckle assembly 4, which facilitates the accurate engagement and connection of the locking buckle 42 with the locking rod 52.
[0032] A left inner chamfer 59 is provided at the top of the left inner upper limit edge 57, and a right inner chamfer 510 is provided at the top of the right inner upper limit edge 58. Correspondingly, a left outer chamfer 49 is provided at the top of the left lower limit edge 47, and a right outer chamfer 410 is provided at the top of the right lower limit edge 48. The provision of the left inner chamfer 59, right inner chamfer 510, left outer chamfer 49, and right outer chamfer 410 can prevent interference between the inner lock seat cover 54 and the outer lock cover 43 when the latch assembly 4 and the lock seat assembly 5 are engaged, and facilitate the smooth engagement and connection of the latch 42 and the lock rod 52.
[0033] The outer lock seat cover 53 is further provided with a left limiting edge 511 and a right limiting edge 512, and the inner lock seat cover 54 is further provided with a left limiting edge 513 and a right limiting edge 514.

Correspondingly, a left lock cover chamfer 413 is provided at the top of the left limiting edge 411 of the lock cover, and a right lock cover chamfer 414 is provided at the top of the right limiting edge 412 of the lock cover.
[0036] A spherical protrusion 517 is provided on the outer wall of the outer lock seat cover 53. The spherical protrusion 517 covers the outside of the lock hole 51 and the lock rod 52. The spherical protrusion 517 is also located above the lock handle 41, which protects the lock handle 41 from accidental contact and damage, and also prevents accidental opening operations. Moreover, when opening the case, after turning the lock handle 41 upward with your finger, the lock handle 41 rotates exactly to the spherical protrusion 517, which lifts the folding plate 3 that has been disengaged from the case body 1, making the opening operation more convenient. No other extra operations are required when opening the case, achieving the effect of opening the case with one hand.
[0037] When closing the box, press down on the folding plate 3, causing the locking rod 52 to press against the latch 42 and force the latch 42 to rotate into the lock hole 51 to avoid obstruction. After the folding plate 3 is pressed into place, the latch 42 is reset by the return spring 46 and locked with the locking rod 52. The folding plate 3 is locked onto the box body 1, completing the box closing operation.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
