DETAILED DESCRIPTION
[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] Combined with reference Figure 1-Figure 5The utility model provides an EPP turnover box, including a turnover bottom plate 1 made of EPP material, a pair of turnover side plates 1 3, a pair of turnover side plates 2 4 and a pair of turnover top plates 5. The turnover bottom plate 1 is arranged in a U-shaped structure. The inner space of the turnover bottom plate 1 can provide a storage area for the turnover side plates 1 3. The bottom of the turnover bottom plate 1 is rotatably connected with a roller shaft 2. The roller shaft 2 is provided with a plurality of roller shafts. When the EPP turnover box turns over goods, the roller shaft 2 can give the EPP turnover box the mobility of roller skates. A pair of turnover side plates 1 3 are hinged on the front and rear sides of the turnover bottom plate 1, a pair of turnover side plates 2 4 are hinged on the left and right sides of the turnover bottom plate 1, and the turnover top plate 5 is hinged on the turnover side plates 2 4. The turnover top plate 5 can be hinged on the turnover side plates by hinges. The rotating parts 24 can realize an angular rotation within the range of 0-270 degrees. A partition plug plate 6 is inserted into a pair of rotating side plates 24. Because the rotating side plates 13 are in the width position, after the pair of rotating side plates 13 are stored in the rotating bottom plate 1, the middle position of the rotating bottom plate 1 can provide a storage area for the partition plug plate 6. The side surfaces of the rotating side plates 24 are fixedly connected with positioning columns 7 for plugging in the rotating side plates 3. When the rotating side plates 24 and the rotating side plates 13 are in the upright state, the positioning columns 7 can be inserted into the side surfaces of the rotating side plates 13, which can limit the supporting position of the rotating side plates 13. A pair of rotating top plates 5 are provided with fixings 8 for locking, and the rotating bottom plate 1 is provided with a pair of threaded sleeves 29 threadedly connected with the matching fixings 8.
[0023] It is worth noting that the articulated connection in the present application is achieved through an articulated part such as a hinge.
[0024] Both ends of the partition plug plate 6 are fixedly connected to the limit plates 61, and the side surfaces of the turnover side plates 24 are provided with a plurality of limit slots 12 for inserting the limit plates 61, and the limit slots 12 are provided in a convex structure. When the turnover side plates 24 are unfolded and erected, the partition plug plate 6 with the limit plates 61 can be vertically inserted into the limit slots 12 at the required position. While achieving the effect of lateral anti-slippage, the partition plug plate 6 can realize the effect of space separation on the one hand, and on the other hand, it can pull a pair of turnover side plates 24 through the limit plates 61, so that the stability of the turnover space can be stabilized.
[0025] A plug plate cloth groove 10 is provided on the turnover base plate 1, and baffle boxes 101 connected to the plug plate cloth groove 10 are fixedly connected on the left and right sides of the turnover base plate 1. The setting of the plug plate cloth groove 10, the setting of the plug plate cloth groove 10, and the inner space of the turnover base plate 1 can reserve effective storage space for the partition plug plate 6 with the limiting plate 61, so as to meet the convenience of storing and receiving the partition plug plate 6. The setting of the baffle box 101, after the partition plug plate 6 is superimposed on the turnover base plate 1, at this time, the baffle box 101 can provide limiting for both ends of the partition plug plate 6 to prevent the partition plug plate 6 from being detached when stored.
[0026] A storage groove 11 is provided on the turnover top plate 5, and a handle 51 is rotatably connected in the storage groove 11. The handle 51 can conveniently pull the EPP turnover box for movement.
[0027] There are two groups of fixing members 8, which include a pair of threaded sleeves 81 fixedly connected to a pair of revolving top plates 5 and arranged in parallel, and a fastening bolt 82 threadedly connected to the pair of threaded sleeves 81. The threaded sleeves 81 are double-screw hole structures, and the double screw holes are vertically distributed. The advantage of this design is that the threaded sleeves 81 can be connected to the threaded sleeves 81 through the fastening bolts 82, or the threaded sleeves 81 can be connected to the threaded sleeves 9 through the fastening bolts 82.
[0028] Specifically, when the turnover bottom plate 1, a pair of turnover side plates 1 3, a pair of turnover side plates 2 4 and a pair of turnover top plates 5 are rotated and unfolded in succession, and the partition plug plate 6 is inserted into the pair of turnover side plates 2 4, and the positioning column 7 is inserted into the turnover side plate 1 3, an effective turnover space can be enclosed. At this time, the pair of turnover top plates 5 can also be in an open and closed state. By threading the fastening bolts 82 onto the pair of threaded sleeves 1 81, the pair of turnover top plates 5 can be locked, thereby achieving the packaging effect of the product and ensuring the reliability of movement.
[0029] The threaded sleeve 9 arranged on the turnover base plate 1 is threadedly connected with the fastening bolt 82 .
[0030] Specifically, when the EPP turnover box needs to be folded, the partition plug 6 can be removed first, and the connection between the turnover side panel 1 3 and the turnover side panel 2 4 can be released. At this time, the turnover side panel 1 3 can be flipped inward and folded to the inner side of the turnover bottom plate 1, and the partition plug 6 can be placed in the middle position of the turnover bottom plate 1. Then, the turnover side panel 2 4 can be folded in facing the inner side of the turnover bottom plate 1 and pressure can be applied to the turnover side panel 1 3. Finally, the turnover top plate 5 can be folded onto the turnover side panel 2 4. At this time, the threaded sleeve 1 81 on the turnover side panel 2 4 can be arranged in parallel with the threaded sleeve 2 9 on the turnover bottom plate 1. In this way, the fastening bolts 82 in the fixing part 8 can be used to connect the threaded sleeve 1 81 and the threaded sleeve 2 9, so that the EPP turnover box in the storage state can be tightened.
