Technical Field

[0001] The invention relates to the field of cartons, in particular to a corrugated carton and a processing method thereof. Background Art

[0002] Corrugated paperboard is a common and widely used packaging product, which has penetrated into every aspect of our daily life. Because of its extremely wide range of applications, its usage has always been at the forefront of various packaging products.

[0003] At present, in order to facilitate the handling of corrugated cardboard boxes, two long carrying holes are symmetrically processed on both sides of the corrugated cardboard boxes, so that the handling personnel can insert their hands into the two long carrying holes and pick up the cardboard boxes for handling. However, when the items in the cardboard boxes are heavy, since the edges of the two long holes are only ordinary corrugated cardboards, they are very easy to be damaged, affecting the handling. Summary of the invention

[0040] like Figure 1-12 As shown, a detailed description of the corrugated box:

[0041] A corrugated paper box comprises a main box body 101, and transversely long holes 102 symmetrically arranged on both side surfaces of the main box body 101, wherein a hole ring 201 is slidably arranged in the transversely long hole 102, and a guard plate 202 is fixed to the outside of the hole ring 201 away from the main box body 101, and a rounded corner is arranged at the connection between the guard plate 202 and the hole ring 201, and a buckle plate 301 is sleeved on the inner end of the hole ring 201 located in the main box body 101.

[0042] The guard plate 202 is placed outside the main box 101, and the gusset plate 301 is placed inside the gusset plate 301, so that the hole ring 201 is installed in a limited position in the horizontal long hole 102. When the box is transported, the transporter puts his / her hands in the two hole rings 201, and the hole rings 201 bear the pressure of the transport to transport the box, thereby preventing the horizontal long hole 102 from being damaged.

[0043] Moreover, by providing a rounded corner at the connection between the guard plate 202 and the hole ring 201, the comfort of the hand during carrying is improved.

[0044] Further:

[0045] A bayonet 103 is provided in the middle of the lower end of the transverse long hole 102 , and a clamping block 203 is provided in the middle of the lower end of the hole ring 201 .

[0046] The block 203 cooperates with the bayonet 103 to ensure that the hole ring 201 is located in the middle of the transverse long hole 102, and then ensure that the hole ring 201 is located in the middle of the box body, so that the force is evenly applied during transportation.

[0047] Moreover, when the transverse long hole 102 opened on the box body is long, the block 203 cooperates with the bayonet 103 to prevent the hole ring 201 from sliding in the transverse long hole 102, thereby ensuring stability during transportation and being able to adapt to the installation of transverse long holes 102 of different sizes.

[0048] Further:

[0049] The block 203 and the corresponding guard plate 202 are penetrated by a step hole 204 , and the corresponding position of the buckle plate 301 is provided with a cotter pin 302 .

[0050] When the pinch plate 301 is put on the hole ring 201, the split pin 302 is aligned with the step hole 204 at the same time, and the split pin 302 is closed through the opening on the split pin 302, slides over the step in the step hole 204, and then automatically elastically recovers, so that the convex edge on the split pin 302 is engaged with the step in the step hole 204, thereby forming a guard plate 202 and a pinch plate 301 fixedly installed at the inner and outer limits of the side of the main box body 101;

[0051] Moreover, the cotter pin 302 can be made to slide out of the step hole 204 by pulling the buckle plate 301 with force, so that the guard plate 202 and the buckle plate 301 can be quickly installed and disassembled, so as to adapt to the transportation of multiple main boxes 101 through a set of guard plate 202 and buckle plate 301 structures.

[0052] like Figure 1-12 As shown:

[0053] A connecting plate 401 is fixedly installed at the lower end of the guard plate 202, and support plates 402 are provided at both ends of each connecting plate 401. A reel 501 passes through the two support plates 402 on the same connecting plate 401, and a belt 601 is connected between the two reels 501 to protect the lower end of the main box body 101.

[0054] By installing and fixing the connecting plate 401 with the guard plate 202 and the buckle plate 301 on the same side, the two ends of the bag strap 601 are fixed to the side of the main box body 101, thereby forming a bag protection for the lower end of the main box body 101, thereby further enhancing the strength of the lower end of the main box body 101 during transportation, thereby enhancing the transportation strength of the lower end of the main box body 101.

[0055] Further:

[0056] The guard plate 202 extends downwardly to have an extended outer plate 205, and both ends of the extended outer plate 205 are provided with holes Ⅰ206. The buckle plate 301 extends downwardly to have an extended inner plate 303, and both ends of the extended inner plate 303 are provided with holes Ⅱ304, and the two holes Ⅱ304 are respectively coaxially arranged with the two holes Ⅰ206. The connecting plate 401 is provided with plug posts 404 at both ends close to the main box body 101, and the two plug posts 404 are respectively inserted into the two holes Ⅰ206 and penetrate the side of the main box body 101 and insert into the two holes Ⅱ304 to form the installation of the connecting plate 401.

[0057] Two limiting rails 305 are symmetrically arranged on the inner side of the buckle plate 301 , and plug plates 405 are slidably arranged in the two limiting rails 305 . The two plug plates 405 are respectively inserted into the two plug posts 404 to fix the plug posts 404 .

[0058] The plug plates 405 are each provided with a push block 406 at the adjacent ends thereof.

[0059] The connecting plate 401 is inserted into the two holes Ⅰ206 through two plug posts 404 and penetrates the side of the main box 101 and is inserted into the two holes Ⅱ304 to form the installation of the connecting plate 401. At the same time, the push block 406 is pushed to make the plug plate 405 slide in the limit track 305 and then inserted into the through hole on the plug post 404, thereby forming the plug-in locking of the plug post 404, so that the connecting plate 401 is installed and fixed with the guard plate 202 and the buckle plate 301 on the same side;

[0060] At the same time, this installation method is a detachable installation that can be recycled. Therefore, when the bag belt 601 is not needed to protect the lower end surface of the main box body 101, the connecting plate 401 can be removed, thereby reducing the space occupied by the main box body 101 and facilitating placement.

[0061] Further:

[0062] The reel 501 is axially provided with a slot 507 , and both ends of the strap 601 are provided with insertion strips 602 , which are respectively inserted and slid into the two slots 507 .

[0063] A circular plate Ⅰ502 and a circular plate Ⅱ504 are fixed to both ends of the reel 501 respectively. A plurality of pins 503 are evenly arranged on the circumferential direction of the circular plate Ⅰ502 close to the reel 501, and a plurality of insertion holes 403 are arranged on the support plate 402 corresponding to the circular plate Ⅰ502. A torsion plate 505 is fixed to the side of the circular plate Ⅱ504 away from the reel 501, and a spring 506 is arranged between the circular plate Ⅱ504 and the support plate 402 on the same side.

[0064] By pressing the torsion plate 505, the circular plate II 504 squeezes the spring 506, and then the reel 501 drives the circular plate I 502 to slide the plurality of plug posts 503 out of the plurality of plug holes 403, and then the torsion plate 505 is rotated to drive the reel 501 to rotate, and then the slot 507 drives the insert strip 602 to wind the pocket belt 601 around the reel 501, and the overall length of the pocket belt 601 is adjusted so as to adapt to the pocket protection at the lower end of boxes of different sizes during installation;

[0065] Moreover, after adjusting the appropriate length, the torsion plate 505 is released, and the elastic force of the spring 506 will push the circular plate II 504 to drive the multiple plug posts 503 to approach the multiple plug holes 403 and insert them at the most appropriate position to complete the locking of the reel 501.
