[0002] The low elasticity and high toughness of low-elasticity, high-toughness ropes can provide a more solid support due to their own low elasticity and high toughness. When subjected to strong forces for a long time, they are difficult to restore their own shape due to their low elasticity, and will undergo a small plastic deformation and become longer. Corrugated boxes are widely used in product transportation packaging. The current corrugated boxes are reinforced by installing solid hard plates at the corners, which can effectively reinforce the corrugated boxes. However, the center of the corrugated box is far away from the high-strength corners, and it needs to rely on the strength of the corrugated box itself to resist external impact forces. It will still deform when subjected to external impacts. Utility Model Content

[0018] See also Figure 1-Figure 4The utility model provides the following technical solutions: an impact-resistant corrugated cardboard box, comprising a corrugated cardboard box body 1 and a cardboard box reinforcement plate 11, a clearance hole 12 is provided between two adjacent corrugated cardboard box bodies 1, and a quadrilateral limiting column shell 2 is inserted into the four clearance holes 12, one side of the quadrilateral limiting column shell 2 is fixedly connected to a connecting rope 21, and one side of the quadrilateral limiting column shell 2 is fixedly connected to an adjusting rope 22, an inner winding column 23 is rotatably connected inside the quadrilateral limiting column shell 2, the bottom end of the inner winding column 23 is fixedly connected to an inner ratchet gear 24, and the bottom end of the inner ratchet gear 24 is detachably connected to an outer ratchet ring 25, a number of evenly distributed support plates 3 are detachably connected between the corresponding connecting ropes 21 and the adjusting ropes 22, and a low-elasticity and high-toughness tension rope 31 is detachably connected between two adjacent support plates 3.

[0019] In this embodiment: the staff splices multiple support plates 3 and low-elasticity and high-toughness tight ropes 31 as well as connecting ropes 21 and adjusting ropes 22, and then inserts the quadrilateral limiting column shell 2, adjusting ropes 22 and inner winding column 23 into the yielding socket 12, and forms a low-elasticity inner support grid through the support plates 3 and low-elasticity and high-toughness tight ropes 31. Then the staff engages the support plates 3 at the edge with the connecting ropes 21 and adjusting ropes 22, and connects the support plates 3 and low-elasticity and high-toughness tight ropes 31 through the quadrilateral limiting column shell 2, connecting ropes 21, adjusting ropes 22 and inner winding column 23. The tension rope 31 is used for support. When in use, the staff uses a tool to insert it into the adjustment slot 28, adjusts the rotation of the inner winding column 23, and shrinks and straightens the adjustment rope 22 to straighten the support plate 3 and the low elasticity and high toughness tension rope 31, so that the support plate 3 fits the inner wall of the corrugated cardboard box body 1. With the help of the support plate 3 and the low elasticity and high toughness tension rope 31, the corrugated cardboard box body 1 is supported to enhance the impact resistance of the corrugated cardboard box body 1. After being straightened for a long time on the low elasticity and high toughness tension rope 31, a small plastic deformation occurs, resulting in the support plate 3 and the low elasticity and high toughness tension rope 31 When the box is relaxed, the inner winding column 23 is further rotated to rewind and straighten the adjusting rope 22 again. The inner ratchet gear 24 and the outer ratchet ring 25 are ratchet-engaged, which enables the inner winding column 23 to rotate forward and cannot rotate in the reverse direction. When the corrugated cardboard box body 1 is in an idle state, the staff removes the quadrilateral limiting column shell 2, the inner winding column 23 and the outer ratchet ring 25 from the yielding hole 12, removes the outer ratchet ring 25 from the inner ratchet gear 24, and rotates the inner winding column 23 in the reverse direction to adjust the adjusting rope 22 to a relaxed state to avoid the low elasticity and high toughness tight rope 31 from being stretched for a long time. The fatigue strength decreases due to the fact that the support plate 3 and the low-elasticity and high-toughness tension rope 31 are in a stretched state during use. The inner winding column 23, the inner ratchet gear 24 and the outer ratchet ring 25 cooperate to adjust the tightness of the support plate 3 and the low-elasticity and high-toughness tension rope 31 according to actual use conditions, which can effectively improve the service life of the support plate 3 and the low-elasticity and high-toughness tension rope 31. The support plate 3 and the low-elasticity and high-toughness tension rope 31, the connecting rope 21 and the adjusting rope 22 are all detachably connected. When some of the low-elasticity and high-toughness tension ropes 31 are broken, the staff replaces the new low-elasticity and high-toughness tension ropes 31 to connect the support plate 3.

[0020] One corner of the quadrilateral limiting column shell 2 protrudes from the edges of the two adjacent corrugated cardboard box bodies 1, and the two side surfaces of the protruding corner of the quadrilateral limiting column shell 2 are fixedly connected to the connecting rope 21 and the adjusting rope 22 respectively; the protruding corner of the quadrilateral limiting column shell 2 can facilitate the connection with the connecting rope 21 and the adjusting rope 22, thereby avoiding the connecting rope 21 and the adjusting rope 22 from contacting the corrugated cardboard box body 1 and compressing the corrugated cardboard box body 1 to cause local deformation.

[0021] The movable ends of the connecting rope 21 and the adjusting rope 22 are fixedly connected to the snap-fit ​​connecting column 26, and the snap-fit ​​connecting column 26 is detachably connected to the adjacent support plate 3; by providing the snap-fit ​​connecting column 26, the connection between the connecting rope 21 and the adjusting rope 22 and the support plate 3 can be facilitated.

[0022] A clearance groove 27 is provided on the inner wall of the quadrilateral limiting column housing 2 , and the clearance groove 27 corresponds to the position of the adjustment rope 22 ; the clearance groove 27 can make way for the reeled adjustment rope 22 .

[0023] An adjustment slot 28 is provided at the top of the inner winding column 23; the adjustment slot 28 can facilitate the staff to use the matching tool to rotate the inner winding column 23. During operation, the tool is inserted into the adjustment slot 28 and the inner winding column 23 is rotated by twisting the tool.

[0024] Both ends of the low-elasticity and high-toughness tension rope 31 are fixedly connected to the limited connecting column 32. The low-elasticity and high-toughness tension rope 31 is detachably connected to the support plate 3 through the limited connecting column 32. Limited snap-fit ​​grooves 33 are provided on both sides of the support plate 3. The snap-fit ​​connecting column 26 and the limited connecting column 32 are respectively inserted into the limited snap-fit ​​grooves 33 corresponding to the positions; the cooperation between the limited connecting column 32 and the limited snap-fit ​​groove 33 can facilitate the connection of multiple support plates 3.

[0025] The working principle and usage process of the utility model are as follows: the staff splices multiple support plates 3 and low-elasticity and high-toughness tensioning ropes 31 as well as the connecting ropes 21 and the adjusting ropes 22, and then inserts the quadrilateral limiting column shell 2, the adjusting ropes 22 and the inner winding column 23 into the yielding socket 12, and forms a low-elasticity inner support grid through the support plate 3 and the low-elasticity and high-toughness tensioning rope 31. Then the staff engages the support plate 3 located at the edge with the connecting rope 21 and the adjusting rope 22, and supports the support plate 3 and the low-elasticity and high-toughness tensioning rope 31 through the quadrilateral limiting column shell 2, the connecting rope 21, the adjusting rope 22 and the inner winding column 23. When in use, the staff uses a tool to insert into the adjusting slot 28, adjusts the rotation of the inner winding column 23, shrinks and straightens the adjusting rope 22, so as to tighten the support plate 3 and the low-elasticity and high-toughness tensioning rope 31 Straight, the support plate 3 fits with the inner wall of the corrugated cardboard box body 1, and the corrugated cardboard box body 1 is supported by the support plate 3 and the low-elasticity and high-toughness tension rope 31 to enhance the impact resistance of the corrugated cardboard box body 1. After being stretched for a period of time on the low-elasticity and high-toughness tension rope 31, a small plastic deformation occurs, causing the support plate 3 and the low-elasticity and high-toughness tension rope 31 to relax. The inner winding column 23 is further rotated, and the adjustment rope 22 is rolled and straightened again. When the corrugated cardboard box body 1 is in an idle state, the staff removes the quadrilateral limiting column shell 2, the inner winding column 23 and the outer ratchet ring 25 from the yield socket 12, and after removing the outer ratchet ring 25 from the inner ratchet gear 24, the inner winding column 23 is rotated in the opposite direction to adjust the adjustment rope 22 to a relaxed state to avoid the low-elasticity and high-toughness tension rope 31 being in a stretched state for a long time, resulting in a decrease in fatigue strength.
