[0095] Among them, two positioning columns 23 are fixedly connected to the upper surfaces of the two pushing rods 22.

[0096] Furthermore, two springs 20 are slidably sleeved on the outer surfaces of the two sliding rods 15;

[0097] Among them, the two springs 20 are located in the two inner grooves 16, and the upper ends of the springs 20 are slidably connected to the lower surfaces of the inner fixing blocks 18;

[0098] Among them, the lower ends of the springs 20 are slidably connected to the bottom walls of the inner grooves 16;

[0099] Among them, two limiting grooves 17 are formed on the outer surfaces of the two opposite sides of the two positioning blocks 12;

[0100] Among them, the two limiting grooves 17 communicate with the interiors of the two sliding grooves 21, and the two limiting grooves 17 communicate with the interiors of the two inner grooves 16;

[0101] Among them, two positioning grooves 19 are formed on the top walls of the two limiting grooves 17;

[0102] Among them, the positioning groove 19 is adapted to the positioning post 23, and the positioning groove 19 is slidably connected to the positioning post 23;

[0103] Among them, four mounting blocks 6 in an "n" shape are fixedly sleeved on the outer surfaces of the two rotating shafts 4;

[0104] Among them, wheels 7 are rotatably mounted on the four mounting blocks 6, and the wheels 7 on the left and right sides are arranged in a mirror image.

[0105] Furthermore, a rubber friction pad is fixedly connected to the lower surface of the rotational molding box body 1 to increase the friction force.

[0106] Furthermore, during the process of covering the lid 2 on the rotational molding box body 1, the lid 2 and the rotational molding box body 1 will squeeze the waterproof sealing gasket 25, causing the waterproof sealing gasket 25 to be extruded and deformed until the top wall and the bottom wall of the waterproof sealing gasket 25 are in contact. At this time, under the action of the elastic force released by the waterproof sealing gasket 25 synchronously, the waterproof sealing gasket 25 fits more closely with the upper surface of the rotational molding box body 1 and the reinforcing rubber pad 26, and the contact is more intimate, thereby making the sealing performance and waterproof performance of the rotational molding box body 1 better.

[0107] Further, in the initial state, the rotational molding box body 1 is placed on the ground, and the wheels 7 do not contact the ground. When it is necessary to move the rotational molding box body 1, step on the pedal 11 downward, so that the pedal 11 and the connecting plate 10 rotate around the rotating shaft 4. In this process, the rotating shaft 4 is synchronously driven to rotate, thereby tightening the spring 8 and deforming the spring 8. During the rotation of the rotating shaft 4, the wheels 7 are driven to contact the ground and the rotational molding box body 1 is lifted off the ground as the pedal 11 is stepped on. At this time, push the push rod 22 downward, thereby driving the sliding rod 15, the positioning column 23, the push ball 13 and the inner fixing block 18 to move downward. During the downward movement of the inner fixing block 18, the spring 20 is squeezed, causing the spring 20 to be squeezed and deformed. When the push rod 22 is displaced downward to contact the bottom wall of the chute 21, rotate the push rod 22 at this time so that the push rod 22 rotates into the limit groove 17, and then push the push rod 22 upward to push the positioning column 23 into the positioning groove 19. And at this time, the push rod 22 contacts the top wall of the limit groove 17. At this time, under the action of the released elastic force of the spring 20, the push rod 22 is pushed to closely adhere to the top wall of the limit groove 17. And because the positioning column 23 cooperates with the positioning groove 19, the sliding rod 15 will not rotate or move up and down, thereby synchronously fixing the push ball 13. At this time, release the step on the pedal 11. Under the action of the gravity of the rotational molding box body 1 and the released elastic force of the spring 8, the connecting plate 10 and the pedal 11 are driven to reset. However, after the pedal 11 rotates a small angle (within this angle, the wheels 7 still contact the ground and the rotational molding box body 1 is still separated from the ground), the connecting plate 10 contacts the push ball 13, thereby restricting the connecting plate 10 and making the connecting plate 10 unable to reset. Furthermore, the wheels 7 are positioned, so that the wheels 7 can contact the ground, thereby enabling the rotational molding box body 1 to be moved, facilitating the movement and handling of the rotational molding box body 1, saving manpower, and increasing the practicality of the rotational molding box body 1;

[0108] When it is necessary to transport or place the rotational molding box body 1, step on the pedal 11 at this time, so that the connecting plate 10 does not contact the push ball 13, then push the push rod 22 downward, drive the positioning column 23 to move out of the positioning groove 19, and then rotate the push rod 22 to displace it into the chute 21. At this time, under the action of the released elastic force of the spring 20, the sliding rod 15, the positioning column 23, the push ball 13 and the inner fixing block 18 will be pushed upward, thereby driving the push ball 13 to reset. At this time, release the step on the pedal 11. Under the action of the gravity of the rotational molding box body 1 and the released elastic force of the spring 8, the wheels 7 are driven to return to the initial state, so that the lower surface of the rotational molding box body 1 contacts the ground, thereby making the rotational molding box body 1 more stable during transportation or placement, avoiding the rotational molding box body 1 from shaking easily during transportation due to the wheels, and ensuring the stability and practicality of the rotational molding box body 1;

[0109] As described above, the rubber friction pad can increase the friction between the rotomolding box body 1 and the ground, thereby ensuring the stability of the rotomolding box body 1 during transportation or placement.

[0110] Working principle: When the device is in use, in the initial state, the rotomolding box body 1 is placed on the ground and the wheels 7 do not contact the ground. When it is necessary to move the rotomolding box body 1, step on the pedal 11 downward, so that the pedal 11 and the connecting plate 10 rotate around the rotating shaft 4. In this process, the rotating shaft 4 is synchronously driven to rotate, thereby tightening the spring 8 and deforming the spring 8. During the rotation of the rotating shaft 4, the wheels 7 are driven to contact the ground and the rotomolding box body 1 is lifted off the ground as the pedal 11 is stepped on. At this time, push the push rod 22 downward, thereby driving the sliding rod 15, the positioning column 23, the push ball 13 and the inner fixing block 18 to move downward. During the downward movement of the inner fixing block 18, the spring 20 is extruded, causing the spring 20 to be deformed by extrusion. When the push rod 22 moves downward to contact the bottom wall of the chute 21, rotate the push rod 22 at this time, so that the push rod 22 rotates into the limit groove 17, and then push the push rod 22 upward to push the positioning column 23 into the positioning groove 19, and at this time the push rod 22 contacts the top wall of the limit groove 17. At this time, under the action of the released elastic force of the spring 20, the push rod 22 is pushed to closely adhere to the top wall of the limit groove 17, and because the positioning column 23 cooperates with the positioning groove 19, the sliding rod 15 will not rotate or move up and down, thereby synchronously fixing the push ball 13. At this time, release the step on the pedal 11. Under the action of the gravity of the rotomolding box body 1 and the released elastic force of the spring 8, the connecting plate 10 and the pedal 11 are driven to reset. However, after the pedal 11 rotates a small angle (within this angle, the wheels 7 still contact the ground and the rotomolding box body 1 is still separated from the ground), the connecting plate 10 contacts the push ball 13, thereby restricting the connecting plate 10 and making the connecting plate 10 unable to reset, and then the wheels 7 are positioned, so that the wheels 7 can contact the ground, and then the rotomolding box body 1 can be pushed to move, which is convenient for moving and handling the rotomolding box body 1, saving manpower, and thus increasing the practicality of the rotomolding box body 1;

[0111] When it is necessary to transport or place the rotational molding box body 1, step on the pedal 11 at this time, so that the connecting plate 10 does not contact the pushing ball 13, and then push down the pushing rod 22 to drive the positioning column 23 to move out of the positioning groove 19, and then rotate the pushing rod 22 to make its displacement into the sliding groove 21. At this time, under the action of the released elastic force of the spring 20, the sliding rod 15, the positioning column 23, the pushing ball 13 and the inner fixing block 18 will be pushed upward, thereby driving the pushing ball 13 to reset. At this time, release the stepping on the pedal 11. Under the action of the gravity of the rotational molding box body 1 and the released elastic force of the spring 8, the wheels 7 are driven to return to the initial state, so that the lower surface of the rotational molding box body 1 contacts the ground, thereby making the rotational molding box body 1 more stable during transportation or placement, avoiding the rotational molding box body 1 from shaking easily due to the wheels during transportation, and ensuring the stability and practicability of the rotational molding box body 1.
