[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0029] In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.
[0030] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0031] During the container stacking operation, the transfer of the container is realized by a heavy machinery such as a forklift or a crane, and the landing position is finely adjusted to realize the stacking and placement of the upper and lower containers. The operation is rather inconvenient. Among them, when stacking the upper container, it is necessary to use a lock to hook the matching corner fittings on the upper and lower containers to ensure neat stacking and reduce the risk of dumping. Therefore, the overall operation efficiency is not ideal.
[0032] Therefore, the embodiments of the present application provide a guiding and positioning corner fitting, a container corner fitting pair and a container, aiming to improve the convenience of container stacking and placement, the landing operation efficiency and the safety of container stacking to a certain extent.
[0033] See Figure 1 and Figure 2 , in some embodiments, the corner fittings on the container are mostly arranged in the eight corner areas of the container body 300 and serve as fasteners for lifting and stacking.
[0034] The guiding and positioning corner fitting 100 may include a body 110, and a positioning boss 120 protruding from the body 110 may be provided on the body 110. During the container alignment and stacking operation, when the container equipped with the body 110 is stacked and landed, the positioning boss 120 is correspondingly clamped and embedded into the card slot 211 of the basic corner fitting 200 provided on the lower-layer container, so as to realize the accurate landing of two layers of containers, achieve the neat stacking of the upper and lower-layer containers, simplify the stacking alignment operation to a certain extent, and improve the operation efficiency; on the other hand, it can also limit the lateral displacement between the upper and lower-layer containers through the clamping fit of the positioning boss 120 and the card slot 211, so as to maintain the stability of the stacking posture and position and the safety of the stack.
[0035] In some embodiments, in order to improve the convenience of the positioning boss 120 for alignment and clamping, the positioning boss 120 may be set as a cone 121, and the thick part of the cone 121 is connected to the body 110. When aligning two layers of containers, due to the conical characteristics of the positioning boss 120, when there is a certain misalignment of the containers, the head end of the positioning boss 120 can be accurately clamped and embedded into the card slot 211 on the aligned basic corner fitting 200, and then the container can be lowered. Under the guidance of the conical surface of the positioning boss 120, the alignment can be adjusted adaptively and neatly stacked.
[0036] In some embodiments, the cone 121 may be set as a quasi-rectangular cone, that is, the cross-section of the cone 121 of the positioning boss 120 is approximately rectangular, and correspondingly, it can only be paired and embedded into a rectangular card slot, having a certain degree of alignment and deviation correction ability, which is convenient for adjusting the alignment and landing of the upper-layer lowered container.
[0037] In some embodiments, in order to improve the smoothness of the clamping operation of the positioning boss 120, an arc chamfer 121a may be opened at the edge of the quasi-rectangular cone to prevent its edge from abutting against the edge of the card slot 211 and affecting the smoothness of the landing.
[0038] In some embodiments, the side surface in the width direction of the quasi-rectangular cone 121 may also be an arc surface 121b to improve the smoothness of the landing of the positioning boss 120.
[0039] In some embodiments, in order to reduce the overall weight, the body 110 may be set as a hollow part; similarly, the basic corner fitting may also be set as a hollow part.
[0040] In some embodiments, in order to facilitate lifting, a first locking through hole 111 may be provided on the body 110. It is worth noting that the first locking through hole 111 may also be used as a mounting hole for mounting a tensioning lock, which is used to tighten the corner fittings of the upper and lower containers in the vertical direction to prevent the positioning boss from detaching upward from the slot of the lower corner fitting, so as to maintain the stability of the stacking state.
[0041] In some embodiments, the body 110 may be configured as a square piece.
[0042] In another aspect of the embodiment of the present application, there is also provided a container corner fitting pair, comprising the above-mentioned guide positioning corner fitting 100 and a basic corner fitting 200 matched therewith; wherein, a slot 211 adapted to the positioning boss 120 is provided on the basic corner fitting 200.
[0043] Generally speaking, when two containers are stacked, the guide positioning corner piece 100 is aligned with the basic corner piece 200, and the positioning boss 120 is inserted into the slot 211.
[0044] In some embodiments, in order to facilitate the lifting and locking of the container, the basic corner piece 200 is also provided with a second locking through hole 212 that cooperates with the first locking through hole 111 provided on the main body 110 .
[0045] After the upper container is in place, the upper container can be locked by hooking the locking member to the first locking through hole 111 and the second locking through hole 212 .
[0046] On the other hand, an embodiment of the present application further provides a container, including a container body 300 and the container corner fitting pair; the guide positioning corner fitting 100 is arranged at the bottom of the container body 300, and the basic corner fitting 200 is arranged at the top of the container body 300.

At the same time, the cooperation between the positioning bosses and the card slots can also limit the lateral displacement of the container, thereby maintaining the stability and safety of the stacking state.
