[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3 , an environment-friendly and wear-resistant folding box, comprising a folding base 1, rectangular side plates 2, folding side plates 3 and a rectangular cover plate 4. The number of the rectangular side plates 2 and the folding side plates 3 is two. The folding base 1 is symmetrically hinged with the rectangular side plates 2 at the front and rear ends of the upper end. The folding side plates 3 are respectively and commonly hinged with the left and right sides of the two rectangular side plates 2. The rectangular cover plate 4 is inserted between the rectangular side plates 2 and between the rectangular cover plate 4 and the folding side plates 3; the folding base 1 is composed of two folding plates 11 arranged front and rear and hinged by a first hinge rod 12. The folding side plates 3 are composed of two rectangular plates 30 arranged front and rear and hinged by a second hinge rod 31. Four corners at the lower end of the rectangular cover plate 4 are fixedly installed with first limiting insertion rods 41, and two sides at the middle part of the lower end of the rectangular cover plate 4 are symmetrically and fixedly installed with limiting blocks 42; a first alignment frame 13 is jointly arranged between the first hinge rod 12 and the folding plate 11, a second alignment frame 32 is jointly arranged between the second hinge rod 31 and the rectangular plate 30, a first control frame 21 for controlling the movement of the first alignment frame 13 is arranged in the rectangular side plate 2, a second control frame 33 for controlling the movement of the second alignment frame 32 is arranged in the rectangular plate 30, and an extrusion frame 43 for applying an extrusion force to the first control frame 21 and the second control frame 33 is arranged on the rectangular cover plate 4.

[0027] Refer to Figure 2, the alignment frame 13 includes positioning holes 131. Positioning holes 131 that penetrate through from front to back are symmetrically formed on the left and right sides of the hinge rod 12 on the folding plate 11. Positioning rods 132 are symmetrically and slidably connected to the left and right sides of the folding plate 11 in the front-back direction. The positioning rods 132 are matched with the positioning holes 131 and their central axes are aligned. The corresponding positioning rods 132 on the left and right are fixedly connected by a connecting plate 133. A return spring 134 is fixedly installed at one end of the connecting plate 133 away from the positioning hole 131, and the return spring 134 is fixedly connected to the folding plate 11. When the folding box needs to be folded, the rectangular cover plate 4 is removed. At this time, the control frame 21 no longer contacts the positioning rod 132, and the positioning rod 132 no longer receives the extrusion force. Under the action of the reaction force of the return spring 134, the connecting plate 133 drives the positioning rod 132 to move away from the hinge rod 12 on the folding plate 11, and the positioning rod 132 no longer inserts into the positioning hole 131 of the hinge rod 12, so that the folding plate 11 of the folding box can be folded smoothly.

[0028] It should be noted that part of the structures of the alignment frame 13 and the alignment frame 32 are the same. Among them, the positioning holes 131 in the alignment frame 32 penetrate through the upper and lower parts and are arranged on the hinge rod 31. Positioning rods 132 are symmetrically and slidably connected to the upper and lower parts of the rectangular plate 30 in the front-back direction. The positioning rods 132 are matched with the positioning holes 131 and their central axes are aligned.

[0029] Refer to Figure 2 , the control frame 21 includes a first wedge block 211. First wedge blocks 211 are symmetrically and slidably connected to the left and right sides of the rectangular side plate 2 in the up-down direction. When the folding box is unfolded, the inclined surface of the first wedge block 211 is in contact with and slidably connected to the corresponding positioning rod 132. When the folding box is folded, the first wedge block 211 no longer contacts the corresponding positioning rod 132.

[0030] Refer to Figure 2 , extrusion rods 212 are fixedly installed at the upper ends of the two first wedge blocks 211 on the rectangular side plate 2. Cylindrical springs 213 are fixedly installed at the upper ends of the first wedge blocks 211, and the upper ends of the cylindrical springs 213 are fixedly connected to the rectangular side plate 2.

Second wedge blocks 331 are symmetrically slidably connected to the upper and lower parts of the rectangular plate 30. The upper and lower second wedge blocks 331 are fixedly connected by a linkage rod 332. The inclined surface of the second wedge block 331 is slidably connected to the corresponding positioning rod 132 on the alignment frame 32 in the up-down direction.

[0032] Refer to Figure 2, a contact rod 333 is fixedly installed at the upper end of the upper wedge block two 331. Fixed springs 334 are fixedly installed on the upper side of the upper wedge block two 331 and outside the contact rod 333. The fixed springs 334 are fixedly connected to the rectangular plate 30. An insertion hole rod 335 is fixedly installed at the lower end of the lower wedge block two 331. Matching insertion holes 336 are symmetrically formed on the left and right sides of the folding plate 11. The insertion hole rod 335 is matched with the matching insertion hole 336.

[0033] Refer to Figure 2 , a pressing rod 431 is fixedly installed at the lower end of the rectangular cover plate 4 and directly above the contact rod 333. A cylindrical insertion rod 432 is fixedly installed at the lower end of the rectangular cover plate 4 and directly above the extrusion rod 212.

[0034] Refer to Figure 2 , threaded holes one are formed around the rectangular cover plate 4. Threaded holes two are formed on the rectangular side plate 2 and the folding side plate 3 and below the threaded holes one. Bolts are commonly screwed in the threaded holes one and the threaded holes two. The bolts on the left and right sides are arranged staggeredly, and the bolts on the front and back sides are arranged staggeredly.

[0035] Working principle of the present invention: After manually expanding the folding box on the horizontal ground, put items into the folding box, and then cover the rectangular cover plate 4 on the rectangular side plate 2 and the folding side plate 3. Use the limiting insertion rod one 41 on the rectangular cover plate 4 to insert into the hinge joint of the rectangular side plate 2 and the folding side plate 3 to position the rectangular side plate 2 and the folding side plate 3. The limiting block 42 limits the hinge joint of the rectangular plate 30. At the same time, the pressing rod 431 on the rectangular cover plate 4 contacts the contact rod 333 and squeezes the contact rod 333, thereby driving the upper and lower wedge blocks two 331 to move downward together, driving the positioning rod 132 on the alignment frame two 32 to move towards the hinge joint of the rectangular plate 30, so that the positioning rod 132 on the alignment frame two 32 is inserted into the positioning hole 131 on the alignment frame two 32 to achieve the purpose of positioning the hinge joint between the rectangular plates 30. At the same time, the cylindrical insertion rod 432 contacts the extrusion rod 212 and squeezes the extrusion rod 212, driving the extrusion rod 212 and the wedge block one 211 to move downward, thereby driving the positioning rods 132 on the front and back sides to move towards each other until the positioning rod 132 is inserted into the positioning hole 131 of the hinge rod one 12, so as to position the hinge joint between the folding plate 11 and the rectangular side plate 2. The rectangular cover plate 4 is fixed to the rectangular side plate 2 and between the rectangular cover plate 4 and the folding side plate 3 through bolts.
