Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0028] Please refer to Figures 1-4 , the present utility model provides a new technical solution: a low-temperature resistant rotomolding box body, including a rotomolding box body 1, four support legs 2 are fixedly installed on the lower surface of the rotomolding box body 1, and card slots 3 are opened on the opposite surfaces of the four support legs 2;
[0029] Among them, a fixing mechanism is arranged on the upper surface of the rotomolding box body 1, and the fixing mechanism includes a connecting plate 4, four grooves 5, four sliding holes 6, four spring grooves 7, four fixing rods 8, four rings 9, four first springs 10, four clamping blocks 11, four pull rings 12, six piston rods 13, six second springs 14 and six dampers 15.
[0030] Furthermore, the connecting plate 4 is arranged on the upper surface of the rotomolding box body 1, and four grooves 5 are opened on the upper surface of the connecting plate 4;
[0031] Among them, four sliding holes 6 are respectively opened in the four vertical plates of the connecting plate 4, and the four sliding holes 6 are respectively communicated with the four grooves 5;
[0032] Among them, four spring grooves 7 are respectively opened in the four vertical plates of the connecting plate 4, and the four spring grooves 7 are respectively communicated with the four sliding holes 6.
[0033] Furthermore, four fixing rods 8 are respectively slidably sleeved on the inner surfaces of the four sliding holes 6, and four rings 9 are respectively fixedly sleeved on the outer surfaces of the four fixing rods 8;
[0034] Among them, four first springs 10 are respectively fixedly installed on the opposite surfaces of four rings 9, and the opposite ends of the four first springs 10 are respectively fixedly installed on the inner walls of four spring grooves 7.
[0035] Furthermore, four clamping blocks 11 are respectively fixedly installed on the opposite ends of four fixing rods 8, and the upper surfaces of the four clamping blocks 11 are all arranged in an inclined plane;
[0036] Among them, four pull rings 12 are respectively fixedly installed on the opposite ends of four fixing rods 8.
[0037] Furthermore, six piston rods 13 are respectively fixedly installed on the lower surface of the connecting plate 4, and six second springs 14 are respectively fixedly installed on the lower surfaces of the six piston rods 13.
[0038] Furthermore, six dampers 15 are respectively fixedly installed at the lower ends of the six second springs 14, the six dampers 15 are respectively sleeved on the outer surfaces of the six piston rods 13 in a sliding manner, and the six dampers 15 are respectively fixedly installed on the upper surface of the rotomolding box body 1;
[0039] When the low-temperature resistant rotomolding box body structure is in use, by inserting the four support legs 2 fixedly installed on the lower surface of the rotomolding box body 1 into the four grooves 5 opened on the upper surface of the connecting plate 4, at this time, the four support legs 2 hit the inclined planes of the clamping blocks 11 and apply a rightward thrust to the clamping blocks 11, so that they slide rightward on the inner surface of the sliding holes 6. At the same time, the fixing rods 8 drive the rings 9 fixedly sleeved on the outer surfaces to move rightward. While the rings 9 move rightward, they apply pressure to the first springs 10 fixedly installed on the right surfaces, causing them to contract. At the same time, the fixing rods 8 drive the clamping blocks 11 fixedly installed at the left ends to move rightward. At this time, continue to insert the four support legs 2 into the four grooves 5 opened on the upper surface of the connecting plate 4. At this time, the clamping blocks 11 pass through the clamping grooves 3 opened on the outer surfaces of the support legs 2. At this time, the clamping blocks 11 no longer receive the extrusion force applied by the support legs 2, and at the same time, the first springs 10 are no longer stressed. At this time, the first springs 10 apply a leftward thrust to the rings 9 fixedly installed at the left ends, causing them to move leftward. At the same time, the rings 9 drive the fixing rods 8 fixedly sleeved on the inner surfaces to move leftward. At the same time, the fixing rods 8 apply a leftward thrust to the clamping blocks 11 fixedly installed at the left ends, causing them to move leftward and be clamped into the clamping grooves 3 opened on the outer surfaces of the support legs 2 for fixation. After the connecting plate 4 is pressed, a downward thrust is applied to the two piston rods 13 fixedly installed on the lower surface, causing them to move downward. At the same time, the two piston rods 13 respectively slide downward on the inner surfaces of the two dampers 15. The dampers in this practical new type are liquid dampers, and the liquid in the dampers can be used to slow down the downward movement of the piston rods 13. And while the connecting plate 4 moves downward, it applies pressure to the second springs 14 arranged on the lower surface. The elastic potential energy of the second springs 14 is used to reduce the movement of the connecting plate 4 and maintain the stability of the stacking of the rotomolding box body 1;
[0040] This low-temperature resistant rotational molding box body can be fixed through a clamping structure when the low-temperature rotational molding box bodies are stacked, making it more stable during stacking, making its connection tighter and not easily falling off, further improving the stacking ability of the low-temperature rotational molding box body. Moreover, when the low-temperature rotational molding box bodies are stacked, this low-temperature resistant rotational molding box body can use a damper and a second spring to reduce the pressure on the surface of the rotational molding box body, buffer this part of the pressure, prevent excessive pressure from causing the low-temperature rotational molding box body to crack, and improve the stacking ability of the low-temperature rotational molding box body.
[0041] Working principle: When the structure of this low-temperature resistant rotational molding box body is in use, the four support legs 2 fixedly installed on the lower surface of the rotational molding box body 1 are inserted into the four grooves 5 opened on the upper surface of the connecting plate 4. At this time, the four support legs 2 hit the inclined surface of the latch 11 and apply a rightward thrust to the latch 11, causing it to slide rightward on the inner surface of the sliding hole 6. At the same time, the fixing rod 8 drives the ring 9 fixedly sleeved on the outer surface to move rightward. While the ring 9 moves rightward, it applies pressure to the first spring 10 fixedly installed on the right surface, causing it to contract. At the same time, the fixing rod 8 drives the latch 11 fixedly installed at the left end to move rightward. At this time, continue to insert the four support legs 2 into the four grooves 5 opened on the upper surface of the connecting plate 4. At this time, the latch 11 passes through the card slot 3 opened on the outer surface of the support leg 2. At this time, the latch 11 no longer receives the extrusion force applied by the support leg 2, and at the same time, the first spring 10 is no longer stressed. At this time, the first spring 10 applies a leftward thrust to the ring 9 fixedly installed at the left end, causing it to move leftward. At the same time, the ring 9 drives the fixing rod 8 fixedly sleeved on the inner surface to move leftward. At the same time, the fixing rod 8 applies a leftward thrust to the latch 11 fixedly installed at the left end, causing it to move leftward and be clamped into the card slot 3 opened on the outer surface of the support leg 2 for fixation. After the connecting plate 4 is pressed, a downward thrust is applied to the two piston rods 13 fixedly installed on the lower surface, causing them to move downward. At the same time, the two piston rods 13 respectively slide downward on the inner surfaces of the two dampers 15. The damper in this practical new type is a liquid damper, and the liquid in the damper can slow down the downward movement of the piston rod 13. And while the connecting plate 4 moves downward, it applies pressure to the second spring 14 arranged on the lower surface, and uses the elastic potential energy of the second spring 14 itself to reduce the movement of the connecting plate 4 and maintain the stability of the stacking of the rotational molding box body 1.
