Technical Field
[0001] This utility model belongs to the field of rotational molding box technology, and particularly relates to layered rotational molding boxes. Background Technology
[0002] Rotationally molded boxes are boxes made from high-performance plastic raw materials such as polyethylene or polypropylene through a rotational molding process. In this process, the plastic raw material is placed in a mold, heated and rotated to make the plastic evenly coated on the inner surface of the mold, gradually melting and bonding, and finally cooling and solidifying to form the final shape.
[0003] The following problems exist with rotomolded boxes currently on the market during actual use:
[0004] 1. In actual use, traditional rotomolded boxes are mainly used for storage. When the items stored inside the rotomolded box are small, the items will be located at the bottom of the rotomolded box. At this time, the middle or upper part of the rotomolded box is empty, which makes the space utilization of the rotomolded box small.
[0005] 2. During use, most rotomolded boxes have relatively small surface irregularities, making it inconvenient to move them when the device does not have convenient force-bearing points. Utility Model Content
[0006] The purpose of this invention is to provide a layered rotational molding box to solve the technical problems mentioned in the background art.
[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: a layered rotational molding box, including a box body, a lead screw welded inside the box body, a partition plate provided inside the box body, an internal threaded sleeve fitted inside the partition plate, retaining rings welded to both ends of the internal threaded sleeve, the retaining rings fitting against the surface of the partition plate, a lead screw fitted inside the internal threaded sleeve, a sleeve welded to one end of the internal threaded sleeve, a rotating plate fixedly connected to the surface of the sleeve, the partition plates being evenly distributed, and the lead screws being symmetrically distributed.
[0008] Preferably, a fixing frame is welded to the surface of the housing, a handle is sleeved inside the fixing frame, a second external threaded rod is welded to the side of the handle, a sliding groove is opened on the side of the fixing frame, the second external threaded rod is located inside the sliding groove, an extrusion turntable is sleeved on the surface of the second external threaded rod, one end of the extrusion turntable is attached to the surface of the fixing frame, and the handles are symmetrically distributed.

[0010] Preferably, a first fixing piece is welded to the surface of the box cover, a first external threaded rod is welded to the bottom of the first fixing piece, a second fixing piece is welded to the surface of the box body, a groove is formed on the surface of the second fixing piece, the first external threaded rod is located inside the groove, a nut is sleeved on the surface of the first external threaded rod, and one end of the nut is attached to the second fixing piece.
[0011] Preferably, the surface of the box is fixedly connected to a card frame, the bottom of the box is fitted with an anti-slip frame, the anti-slip frame has a card groove inside, and the card frame is engaged inside the card groove.
[0012] Preferably, the first fixing plates are symmetrically distributed, and the first external threaded rods are symmetrically distributed.
[0013] The layered rotational molding box of this utility model has the following advantages:
[0014] 1. This layered rotomolded box features a screw rod welded inside the box body, along with internal partitions. An internally threaded sleeve is fitted inside each partition, with retaining rings welded to both ends of the sleeve. These retaining rings conform to the partition surface, limiting the internally threaded sleeve within the partitions and providing rotational flexibility. A screw rod is then fitted inside the internally threaded sleeve, and a sleeve is welded to one end of the sleeve. A rotating plate is fixedly connected to the sleeve surface. The partitions are evenly spaced, and the screw rods are symmetrically distributed. When in use… During installation, the rotating plate can be rotated first, which will drive the internal threaded sleeve to rotate. Under the action of the lead screw, the partition can be moved until the internal threaded sleeve disengages from the lead screw. At this point, the partition can be removed, and items can be placed inside the box. After the items are placed, the partition can be installed on the lead screw. When installing the partition, simply put the internal threaded sleeve on the lead screw. Then, by rotating the rotating plate, the partition can be adjusted to a suitable position, and items can be placed on the partition again. This improves the space utilization rate inside the box.
[0015] 2. This layered rotational molding box features a fixed frame welded to the box surface, with handles fitted inside the frame. A second externally threaded rod is welded to the side of the handle. A groove is created on the side of the fixed frame, housing the second externally threaded rod. An extrusion turntable is fitted onto the surface of the second externally threaded rod, with one end of the turntable resting against the fixed frame surface. The handles are symmetrically distributed. When the device needs to be moved, the groove allows for movement of the handles. Once the handle is in the desired position, the extrusion turntable is rotated, increasing the friction between the handle and the fixed frame, thus securing the handle. The handle can then be used as a force point to lift and move the device, making it very convenient to use. Attached Figure Description

[0029] To better understand the purpose, structure, and function of this utility model, the layered rotational molding box of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] like Figure 1-6As shown, the layered rotational molding box of this utility model includes a box body 1, a lead screw 4 welded inside the box body 1, a partition 3 inside the box body 1, an internal threaded sleeve 5 sleeved inside the partition 3, and retaining rings 6 welded to both ends of the internal threaded sleeve 5. The retaining rings 6 fit against the surface of the partition 3. By installing the retaining rings 6, the internal threaded sleeve 5 can be limited inside the partition 3, and the internal threaded sleeve 5 can be rotated, providing a basis for subsequent adjustment of the position of the partition 3. It is very convenient to use. The lead screw 4 is sleeved inside the internal threaded sleeve 5, and a sleeve 7 is welded to one end of the internal threaded sleeve 5. A rotating plate 8 is fixedly connected to the surface of the sleeve 7. The partitions 3 are evenly distributed, and the lead screw 4 is symmetrically distributed. In this fabric-type device, by installing a partition 3, when using the device, first rotate the rotating plate 8, which drives the internal threaded sleeve 5 to rotate. At this time, under the action of the lead screw 4, the partition 3 can be moved until the internal threaded sleeve 5 disengages from the lead screw 4. At this point, the partition 3 can be removed, and items can be placed inside the box 1. After the items are placed, the partition 3 can be installed on the lead screw 4. When installing the partition 3, simply put the internal threaded sleeve 5 onto the lead screw 4. Then, by rotating the rotating plate 8, the partition 3 can be adjusted to a suitable position, and items can be placed on the partition 3 again. This improves the space utilization rate inside the box 1.
[0031] A fixed frame 18 is welded to the surface of the housing 1. A handle 22 is fitted inside the fixed frame 18. A second external threaded rod 20 is welded to the side of the handle 22. A sliding groove 19 is opened on the side of the fixed frame 18. The second external threaded rod 20 is located inside the sliding groove 19. A pressing turntable 21 is fitted onto the surface of the second external threaded rod 20. One end of the pressing turntable 21 is attached to the surface of the fixed frame 18. The handles 22 are symmetrically distributed. By installing the handles 22, when the device needs to be moved, the sliding groove 19 can be used to move the handles 22. After the handles 22 are moved to the appropriate position, the pressing turntable 21 can be rotated to increase the friction between the handles 22 and the fixed frame 18, thereby fixing the handles 22. Then, the handles 22 can be used as the force point, and the device can be lifted and moved directly through the handles 22, which is very convenient to use.
[0032] A fixing block 11 is welded to the surface of the housing 1, and a bushing 12 is welded to the surface of the fixing block 11. A shaft 10 is sleeved inside the bushing 12. Fixing brackets 9 are welded to both ends of the shaft 10. A housing cover 2 is welded to one end of the fixing bracket 9. The surface of the housing cover 2 is attached to the top of the housing 1. By installing the shaft 10 and the bushing 12, the shaft 10 and the bushing 12 can provide a rotation effect for the housing cover 2, thereby allowing the housing cover 2 to close the housing 1 and provide protection for the inside of the housing 1.
[0033] A first fixing plate 13 is welded to the surface of the lid 2, and a first external threaded rod 14 is welded to the bottom of the first fixing plate 13. A second fixing plate 15 is welded to the surface of the box body 1. A groove 16 is formed on the surface of the second fixing plate 15, and the first external threaded rod 14 is located inside the groove 16. A nut 17 is sleeved on the surface of the first external threaded rod 14, and one end of the nut 17 is attached to the second fixing plate 15. By installing the first external threaded rod 14, when the lid 2 is in the closed position, the first external threaded rod 14 will be located inside the groove 16. At this time, the nut 17 can be installed on the surface of the first external threaded rod 14 until one end of the nut 17 is attached to the second fixing plate 15, which can provide a fixed effect for the lid 2 after it is closed, and the stability is strong during use.
[0034] A frame 25 is fixedly connected to the surface of the housing 1, and an anti-slip frame 23 is fitted onto the bottom of the housing 1. A slot 24 is opened inside the anti-slip frame 23, and the frame 25 is engaged inside the slot 24. By installing the anti-slip frame 23, when the device is placed on the ground, the anti-slip frame 23 can provide an anti-slip effect between the bottom of the device and the ground, so that the device will not easily move and improve the stability of the device after placement.
[0035] The first fixing plate 13 is symmetrically distributed, and the first external threaded rod 14 is symmetrically distributed. The distribution of the first external threaded rod 14 can further improve the fixing strength when the first external threaded rod 14 is used to fix the box cover 2, and improve the stability after fixing during use.
[0036] The working principle of this layered rotational molding box is as follows: When using this device, the partition 3 should be removed first. Then, rotate the rotating plate 8 to rotate the internal threaded sleeve 5. Under the action of the lead screw 4, the partition 3 can be moved until the internal threaded sleeve 5 disengages from the lead screw 4. At this point, the partition 3 can be removed, and the device can be used. Since the lead screw 4 is welded inside the box body 1, and the partition 3 is installed inside the box body 1, with the internal threaded sleeve 5 fitted inside the partition 3, and retaining rings 6 welded to both ends of the internal threaded sleeve 5, the retaining rings 6 fit against the surface of the partition 3, thus limiting the internal threaded sleeve 5 to the partition. Inside the internal threaded sleeve 5, a threaded rod 4 is fitted inside the internal threaded sleeve 5. A sleeve 7 is then welded to one end of the internal threaded sleeve 5, and a rotating plate 8 is fixedly connected to the surface of the sleeve 7. The partitions 3 are evenly distributed, and the threaded rods 4 are symmetrically distributed. Items can then be placed inside the box 1. After the items are placed, the partitions 3 can be installed on the threaded rods 4. To install the partitions 3, simply fit the internal threaded sleeve 5 onto the threaded rod 4. Then, by rotating the rotating plate 8, the partitions 3 can be adjusted to the appropriate position. Items can then be placed on the partitions 3 again. This improves the usability of the box 1. To maximize internal space utilization, once items are placed, the lid 2 can be rotated using the shaft 10 until its bottom is flush with the top of the box body 1. At this point, the first external threaded rod 14 will be located inside the groove 16. A nut 17 can then be installed on the surface of the first external threaded rod 14 until one end of the nut 17 is flush with the second fixing piece 15, providing a secure closing effect for the lid 2. When the device needs to be moved, a fixing frame 18 is welded to the surface of the box body 1, and a handle 22 is fitted inside the fixing frame 18. A second external threaded rod 20 is welded to the side of the handle 22, and a sliding groove 1 is provided on the side of the fixing frame 18. 9. At this time, the second external threaded rod 20 is located inside the slide groove 19, and the extrusion turntable 21 is sleeved on the surface of the second external threaded rod 20. At this time, one end of the extrusion turntable 21 is attached to the surface of the fixed frame 18, and the handles 22 are symmetrically distributed. The slide groove 19 can be used to move the handles 22. When the handles 22 are moved to the appropriate position, the extrusion turntable 21 can be rotated to increase the friction between the handles 22 and the fixed frame 18, thereby fixing the handles 22. Then, the handles 22 can be used as the force point, and the device can be lifted and moved directly through the handles 22, which is very convenient to use.
