[0021] Reference Figures 1 to 4 The utility model is further described.

[0022] A durable trolley case includes a case body 1. Elastic wear-resistant sheets 2 are provided on all four corners of the case body 1. The elastic wear-resistant sheets 2 are telescopically connected to the case body 1. When the elastic wear-resistant sheets 2 are retracted, the surface of the elastic wear-resistant sheets 2 is flush with the surface of the case body 1. When the elastic wear-resistant sheets 2 are extended, the surface of the elastic wear-resistant sheets 2 protrudes from the surface of the case body 1.

[0023] In this embodiment, preferably, electric drive mechanisms are provided at both ends of the elastic wear-resistant sheet 2 .

[0024] like Figure 1 As shown, in this example, preferably, the electric drive mechanism includes an electric telescopic rod 3 , a rechargeable battery is provided in the box body 1 , and the rechargeable battery is electrically connected to the electric telescopic rod 3 .

When the elastic wear-resistant sheet 2 is retracted, the shock-absorbing spring 7 is compressed. When the elastic wear-resistant sheet 2 is extended, the shock-absorbing spring 7 is compressed.

[0027] Specifically, when the elastic wear-resistant plate 2 is retracted, the shock-absorbing spring 7 is compressed, and the compression amount is large. When the elastic wear-resistant plate 2 is extended, the shock-absorbing spring 7 is compressed, and the compression amount is small. When the elastic wear-resistant plate 2 is fully extended, the shock-absorbing spring 7 can be in a relaxed state.

[0028] like Figures 1 to 3 As shown, when the anti-scratch function is needed, the two ends of the elastic wear-resistant sheet 2 are moved by the electric drive mechanism so that both ends are close to the middle, and the middle part of the elastic wear-resistant sheet 2 will protrude outward, thereby providing the box body 1 with an anti-scratch function through the elastic wear-resistant sheet 2 protruding from the box body 1. When not in use, the two ends of the elastic wear-resistant sheet 2 are driven to move in opposite directions by the electric drive mechanism, so that the middle part of the elastic wear-resistant sheet 2 can be retracted to be flush with the surface of the box body 1, thereby improving the aesthetics.

[0033] Specifically, by pushing the pull rod 8, the two connecting rods 9 are driven to push the two ends of the elastic wear-resistant sheet 2 respectively, so that the elastic wear-resistant sheet 2 can be protruded and retracted.

[0034] like Figure 2 As shown, in this example, preferably, limiting plates 4 are provided at both ends of the elastic wear-resistant plate 2, limiting grooves 5 are provided on the limiting plates 4, limiting rods 6 are provided on the box body 1, and the limiting rods 6 pass through the limiting grooves 5, the connecting rod 9 is hinged to the limiting plates 4, and the limiting plates 4 are slidably connected to the box body 1.
