[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention provides a cardboard box for preventing bottom water seepage, including a cardboard box body 1. Reinforcing corner protectors 2 are provided at each of the four corners of the outer wall of the cardboard box body 1, and supporting components 4 are provided on each of the four corner protectors 2. Reinforcing components 3 are provided inside the cardboard box body 1. The reinforcing components 3 support the inner wall of the cardboard box body 1, preventing deformation or even damage caused by external impacts. The supporting components 4 allow the cardboard box body 1 to contact the ground through the reinforcing corner protectors 2, preventing bottom water seepage. The height is also adjustable to accommodate different water depths, further improving the water-proofing effect. The reinforcing component 3 includes a reinforcing base plate 31. Guide holes 32 are provided on all four sides of the outer wall of the reinforcing base plate 31. Guide blocks 33 are slidably connected in each of the four guide holes 32. Reinforcing side plates 34 are fixedly installed on the upper part of each of the four guide blocks 33. Two of the reinforcing side plates 34 have gripping holes 35. The reinforcing base plate 31 is placed on the bottom wall of the carton body 1. The reinforcing side plates 34 are slid in the guide holes 32 through the guide blocks 33 for splicing. Then the reinforcing base plate 31 and the reinforcing side plates 34 are placed in the carton body 1 for reinforcement to prevent deformation and damage caused by external impact.
[0014] like Figure 4 As shown, in some embodiments, the cross-section of the guide block 33 is L-shaped; the structure is simple.
[0015] like Figure 2 As shown, in some embodiments, the support component 4 includes a recess 41 and a threaded block 42 formed in the reinforcing corner 2. The inner wall of the recess 41 is provided with internal threads, and the outer wall of the threaded block 42 is provided with external threads. An embedded plate 43 is fixedly installed at the bottom of the threaded block 42. An embedded hole 46 is provided at the bottom of the reinforcing corner 2. A groove 44 is formed at the bottom of the embedded plate 43. A handle 45 is fixedly installed on the inner wall of the groove 44. The threaded block 42 is threadedly connected to the recess 41. By rotating the handle 45, the embedded plate 43 is rotated, which in turn rotates the threaded block 42, so that the carton body 1 is supported by the embedded plate 43, and the support height can be adjusted to prevent water from seeping into the bottom of the carton body 1.
