Description

Technical Field

[0001] The utility model relates to the technical field of turnover boxes, in particular to a logistics turnover box which is convenient for stacking. Background Art

[0002] Logistics turnover boxes, also known as logistics boxes or turnover boxes, are widely used to package mechanical parts, important home appliances, electronic products and some items. With the rapid development of the Internet of Things, more and more items can be traded online. Logistics companies need to use turnover boxes to transport, distribute, store and circulate items. When transporting a large number of turnover boxes, the number of turnover boxes that can be stacked is usually increased by stacking.

[0003] In order to improve the stability of the turnover box after stacking, the prior art has made many improvements to the turnover box, such as the patent with patent announcement number CN220263612U, which discloses a logistics turnover box that is easy to stack, including a box body, the lower two side edges of the box body are provided with fixed plates, the upper two side edges of the box body are provided with plate grooves, the two ends of the plate grooves are provided with mounting grooves, and the position of the mounting grooves is provided with a fixing device. The utility model sets a fixing device, when one turnover box is stacked on another turnover box, the fixed plate will be installed in the plate groove, the first gear bar in the fixed plate drives the first gear to rotate, when the first gear rotates, it will transmit the transmission force to the second gear bar, the second gear bar extends out of the interior of the fixing device, and is engaged in the open groove on the fixing plate, so that the second gear bar can apply lateral force to the fixing plate, thereby improving the stability between each turnover box and reducing the risk of the turnover box tipping over during the stacking process.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] When the turnover boxes in the above-mentioned comparative documents are stacked, they are installed in the plate groove through a fixed plate, and cooperate with a number of gears and racks to engage with each other. However, in actual operation, when the transporters carry the turnover boxes, the lower position of the turnover box is a visual blind spot for the transporters, and the transporters cannot see the lower part of the turnover box. Therefore, it is difficult to engage the fixed plate in the plate groove at one time. In addition, the above-mentioned setting of a number of racks and gears undoubtedly increases the cost of producing the turnover boxes. Therefore, this field is in urgent need of improving the logistics turnover boxes that are easy to stack, so as to solve the defects of the prior art. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a logistics turnover box that is easy to stack, has a simple structure and is convenient for handling personnel to stack the turnover boxes.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1

[0031] See also Figure 1-Figure 7 A logistics turnover box that is easy to stack, including a box body 1 with an open upper end, a plurality of snap-fitting grooves 2 are provided on the upper end of the box body 1, a plurality of snap-fitting columns 3 adapted to the snap-fitting grooves 2 are provided on the lower end of the box body 1, and a positioning plate 4 with a length greater than the height of the box body 1 is provided on at least one side of the box body 1, the positioning plate 4 is L-shaped and vertical in the height direction, and the inner side of the positioning plate 4 is in contact with the side of the box body 1.

[0032] Specific implementation method of this embodiment: when turnover boxes need to be stacked, a box body 1 with a positioning plate 4 on one side is placed at the position where it needs to be stacked, and the verticality of the positioning plate 4 is checked. The verticality of the positioning plate 4 directly reflects the verticality of several boxes 1 after stacking. Figure 1 When the transporters stack the boxes 1 above, one side of the boxes 1 is pressed against the positioning plate 4 and placed downward, and the locking column 3 is directly inserted into the locking groove 2. The structure is simple and convenient for the transporters to stack the turnover boxes.

[0033] Embodiment 2

[0034] See also Figure 3 , Figure 5 and Figure 6 This embodiment includes the above-mentioned embodiment, which further includes: a plurality of fixing frames 5 adapted to the positioning plate 4 are provided on the side of the box body 1, the positioning plate 4 runs through the fixing frames 5 and the side of the box body 1, and plug-in blocks 6 are fixedly connected at both ends of the fixing frames 5, and a plug-in slot 7 adapted to the plug-in block 6 is opened on the side of the box body 1.

[0035] The specific implementation method in this embodiment is as follows: when the boxes 1 need to be stacked, the fixing frame 5 will be installed on the side of the box 1 that needs to be placed at the bottom. During installation, it will be plugged into the plug-in slot 7 through the plug-in block 6. After the fixing frame 5 is installed, the positioning plate 4 will be plugged between the fixing frame 5 and the side of the box 1. When not in use, the fixing frame 5 and the positioning plate 4 can be removed. The structure is simple, the operation is convenient and the practicability is high.

[0036] Embodiment 3

[0037] See also Figure 4 and Figure 6This embodiment includes all the above embodiments, which further includes: the engaging column 3 is a truncated cone with a wide top and a narrow bottom, the engaging groove 2 is adapted to the engaging column 3, and the end of the engaging column 3 close to the box body 1 is fixedly connected with a threaded column 8, and the threaded column 8 is threadedly connected to the lower end of the box body 1, and a plurality of first anti-suction grooves 9 are opened on the side of the engaging column 3, and a plurality of second anti-suction grooves 10 are opened on the end of the engaging column 3 away from the box body 1, and the height of the engaging column 3 is greater than the depth of the engaging groove 2.

[0038] The specific implementation method in this embodiment is as follows: the cavity in the locking groove 2 is wide at the top and narrow at the bottom, and cooperates with the locking column 3 which is also provided to play a guiding role, so that the locking column 3 is convenient for inserting into the locking groove 2. The locking column 3 can be replaced by the setting of the threaded column 8. At the same time, the horizontality of the lowest box 1 can be adjusted by the threaded column 8, which is convenient for adjusting the verticality of the positioning plate 4. The setting of the first anti-suction groove 9 and the second anti-suction groove 10 prevents the locking column 3 and the locking groove 2 from being engaged for too long, causing the locking column 3 and the locking groove 2 to be adsorbed, making it difficult for the transport personnel to separate the two adjacent boxes 1. The height of the locking column 3 is greater than the depth of the locking groove 2. After the two boxes 1 are stacked, there is a certain gap in the middle to prevent the two adjacent boxes 1 from being adsorbed. At the same time, it can achieve a ventilation effect when transporting items that need ventilation.

[0039] Embodiment 4

[0040] See also Figure 2 and Figure 7 This embodiment includes all the above embodiments, and further includes: a top cover 11 is clamped between the upper ends of several positioning plates 4, and a fastening bolt 12 with one end threadedly connected to the side of the positioning plate 4 passes through the side of the top cover 11.

[0041] Specific implementation method of this embodiment: after several boxes 1 are stacked, several positioning plates 4 can be installed again through the fixing frame 5 respectively, and the top cover 11 can be clamped on the upper end of the several positioning plates 4, and the several positioning plates 4 and the top cover 11 are fixed by tightening bolts 12 to improve the stability of the several boxes 1 after stacking.
