[0035] (III) Beneficial Effects
[0036] Compared with the prior art, this utility model provides a rotational molding box with good impact resistance, which has the following beneficial effects:
[0037] 1. This rotomolded box with good impact resistance divides the box body into different spaces, and items can be placed on the partitions.

This allows for the isolation of items, making it easier to divide and store them, thus increasing the practicality and flexibility of the rotomolded box.
[0038] 2. This rotomolded box has good impact resistance. The reinforced arc plate enhances the impact resistance of the four corners of the box body, preventing the four corners of the box body from cracking when impacted, thereby increasing the strength of the rotomolded box and its practicality.
[0039] 3. This rotomolded box has good impact resistance. When the box is dropped vertically from a certain height during unloading, the weight of the box itself and the weight of the contents put pressure on the buffer spring, causing the spring to compress and deform. The buffer spring can absorb the impact force during the drop, preventing the box from breaking, thus increasing the strength of the box and improving its practicality.
[0040] 4. This rotomolded box has good impact resistance. The elastic deformation of the rubber blocks also buffers the impact force during the drop of the rotomolded box, avoiding cracking of the box body, thereby increasing the strength of the rotomolded box and improving its practicality.

[0049] Please see Figure 1-6 This utility model provides a new technical solution: a rotational molding box with good impact resistance, including a reinforcing base 1, and a sliding groove 2 is provided on the upper surface of the reinforcing base 1;
[0050] Among them, multiple buffer springs 5 are fixedly connected to the bottom wall of the sliding groove 2;
[0051] Among them, the upper ends of multiple buffer springs 5 are fixedly connected to the rotomolded box body 3;
[0052] Among them, the rotomolded box body 3 is slidably connected to the sliding groove 2, and the lower surface of the rotomolded box body 3 extends into the sliding groove 2;
[0053] The rotomolded box body 3 is equipped with a reinforcing mechanism, which includes a vertical rod 6, a reinforcing frame 9, a rubber block 10, a reinforcing arc plate 8, a fixing ring 7, and a handle 11.
[0054] The rotomolded box body 3 is equipped with a dividing mechanism, which includes a partition 12, a cover 4, a positioning plate 13, a positioning groove 14, a connecting groove 15, an inner groove 16, a positioning spring 17, a positioning block 18, and a sliding rod 19.
[0055] Furthermore, multiple positioning plates 13 are fixedly connected to the inner walls of the left and right sides of the rotomolded box body 3.
[0056] Among them, multiple partitions 12 are slidably fitted inside the rotomolded box body 3;
[0057] Two positioning grooves 14 are formed on the outer surfaces of the left and right sides of the corresponding partition 12.
[0058] The positioning groove 14 extends out of the upper and lower outer surfaces of the partition 12;
[0059] The positioning grooves 14 on the left and right sides are slidably connected to the positioning plates 13 on the left and right sides.
[0060] Furthermore, multiple inner grooves 16 are formed on the front inner wall of the corresponding positioning grooves 14;
[0061] Among them, multiple sliding rods 19 are slidably connected within multiple inner grooves 16;
[0062] The rear end of the sliding rod 19 extends into the corresponding positioning groove 14 through the inner groove 16 and contacts the rear inner wall of the positioning groove 14.
[0063] Among them, multiple positioning springs 17 are fixedly connected to the front end of multiple sliding rods 19;
[0064] The positioning spring 17 is located in the corresponding inner groove 16, and the front end of the positioning spring 17 is fixedly connected to the front inner wall of the inner groove 16.
[0065] Furthermore, multiple connecting grooves 15 are formed on the top wall of the corresponding inner groove 16, and the connecting grooves 15 extend upward out of the upper surface of the partition 12.
[0066] Among them, multiple positioning blocks 18 are fixedly connected to the outer surface of multiple sliding rods 19;
[0067] The positioning block 18 is slidably connected to the connecting groove 15.
[0068] Furthermore, the fixing ring 7 is fixedly sleeved on the outer surface of the rotomolded box body 3;
[0069] The cover 4 is installed on the rotomolded box body 3;
[0070] Among them, four reinforcing arc plates 8 are fixedly connected to the lower surface of the fixing ring 7;
[0071] Among them, the reinforcing arc plate 8 is located at the four corners of the rotomolded box body 3;
[0072] Among them, the reinforcing arc plate 8 is bonded to the outer surface of the rotomolded box body 3.
[0073] Furthermore, multiple V-shaped reinforcing frames 9 are fixedly connected between corresponding two reinforcing arc plates 8;
[0074] Among them, four rubber blocks 10 are fixedly connected to the lower surface of four reinforcing arc plates 8, and the lower surface of the rubber blocks 10 is an arc surface;
[0075] Among them, the lower surface of the rotomolded box body 3 is provided with multiple sliding holes, and multiple vertical rods 6 are fixedly connected to the bottom wall of the sliding groove 2;
[0076] Among them, the upper ends of multiple vertical rods 6 slide into the sliding hole.
[0077] Furthermore, in this solution, the multiple buffer springs 5 have sufficient elasticity, so that the buffer springs 5 can provide sufficient support to the rotomolded box 3 when it is empty or when it is loaded with a suitable threshold weight, so that the lower surface of the rotomolded box 3 can maintain a certain distance from the bottom wall of the sliding groove 2, and also ensure that the lower surface of the rotomolded box 3 will not easily slide out of the sliding groove 2 during normal use.
[0078] Furthermore, the reinforced arc plate 8 enhances the impact resistance of the four corners of the rotomolded box body 3, preventing the four corners of the rotomolded box body 3 from cracking when impacted, thereby increasing the strength of the rotomolded box and its practicality.
[0079] Furthermore, in this solution, when the rotomolded box 3 is unloaded and falls vertically from a certain height above the ground, the weight of the rotomolded box 3 itself and the weight of the items inside it both exert a certain pressure on the buffer spring 5, causing the buffer spring 5 to compress and deform. The buffer spring 5 can replace the impact force of the rotomolded box 3 during the falling process, thereby preventing the rotomolded box 3 from breaking, thus increasing the strength of the rotomolded box and improving its practicality.
[0080] Furthermore, in this solution, during the unloading process of the rotomolded box 3, when the rotomolded box 3 is dropped vertically from a certain height above the ground, the weight of the rotomolded box 3 itself and the weight of the items inside it exert a certain pressure on the buffer spring 5, causing the rotomolded box 3 to slide downwards. During this process, the rubber block 10 moves downwards, causing the lower surface of the rubber block 10 to contact the upper surface of the reinforcing base 1 and compress the rubber block 10, causing the rubber block 10 to undergo elastic deformation. This process also buffers the impact force of the rotomolded box 3 during its fall, preventing the rotomolded box 3 from breaking, thereby increasing the strength of the rotomolded box and improving its practicality.
[0081] Furthermore, the partition 12 is slid into the rotational molding box 3, and then the positioning block 18 is pushed forward. As the positioning block 18 moves forward, the sliding rod 19 moves forward simultaneously, causing it to move out of the positioning groove 14. During this process, the positioning spring 17 is compressed, causing it to deform. At this point, the partition 12 is pushed downwards. The positioning plate 13 and the positioning groove 14 are now slidably connected, allowing the partition 12 to slide to any position. When the pushing of the positioning block 18 is released, the positioning spring 17 releases its pressure. Under the action of the elastic force, the sliding rod 19 is driven to reset. At this time, the sliding rod 19 limits the partition 12, so that when the sliding rod 19 moves downward, its lower surface will contact the upper surface of the positioning plate 13. This divides the rotomolded box 3 into different spaces, and items can be placed on the partition 12. The corresponding positioning plate 13 will support the partition 12, so that the partition 12 will not slide downward. This can isolate the items, facilitate the division of items, and make it easier to store items, thereby increasing the practicality and flexibility of the rotomolded box.
[0082] Working principle: When the device is in use, by sliding the partition 12 into the rotomolded box 3 and then pushing the positioning block 18 forward, the sliding rod 19 moves forward synchronously, thus moving the sliding rod 19 forward out of the positioning groove 14. During this process, the positioning spring 17 is compressed, causing it to deform. At this time, the partition 12 is pushed downward, and the positioning plate 13 and the positioning groove 14 are slidably connected without obstruction. The partition 12 can then slide to any position. When the pushing of the positioning block 18 is released, the positioning spring... Under the release force of the spring 17, the sliding rod 19 is driven to reset. At this time, the sliding rod 19 limits the partition 12, so that when the sliding rod 19 moves downward, its lower surface will contact the upper surface of the positioning plate 13. This divides the rotomolded box 3 into different spaces, and items can be placed on the partition 12. The corresponding positioning plate 13 will support the partition 12, so that the partition 12 will not slide downward. This can isolate the items, facilitate the division of items, and make it easier to store items, thereby increasing the practicality and flexibility of the rotomolded box.
