The side face 1-1 is provided with a side hole, the end face 1-2 is provided with an end hole, and the top face 1-3 is provided with a top hole. The side hole, the end hole and the top hole are long round holes. The inner side of the corner fitting body 1 is a cavity communicated with the three holes. The three holes and cavities of the corner fitting body 1 are used for mounting connectors between containers or equipment gripping parts. The above described structure is a known structure of existing container corner fittings.

The corner fitting body 1 is provided with a right-angle notch 1-4 at the connecting corner part of the side surface 1-1 and the end surface 1-2. Specifically, the right-angle groove 1-4 is formed by two perpendicular right-angle surfaces, and the two right-angle surfaces vertically extend from the top surface to the bottom surface of the corner fitting body 1 to form the right-angle groove 1-4 penetrating through the top surface and the bottom surface of the corner fitting body 1. One of the two right-angle surfaces is parallel to the side surface 1-1 of the corner fitting body 1, and the other right-angle surface is parallel to the end surface 1-2 of the corner fitting body 1.

Two right-angle surfaces of the right-angle grooves 1-4 are respectively provided with a sunk pin joint groove 1-5. Specifically, the pin joint grooves 1-5 are sinking grooves formed in two right-angle surfaces of the right-angle grooves 1-4. The pin joint groove 1-5 is a rectangular groove, the distance between the upper end of the pin joint groove 1-5 and the top surface 1-3 of the corner fitting body 1 and the distance between the lower end of the pin joint groove 1-5 and the bottom surface of the corner fitting body 1 are L1, and the distance is more than 30mm and less than L1 and less than 50 mm. The distance between the inner side surface of the pin joint groove 1-5 and the corresponding inner wall of the corner fitting body 1 is L2, 18mm < L2<22 mm. In this embodiment, L1 is 35mm, L2 is 20mm, and the width of the pin slot 1-5 is 10 mm.

The size design can ensure the strength standard of the corner fitting. Under the premise of not changing the original functional structure (the structures of the side face, the end face, the top face, the side hole end holes and the top holes), the pin joint grooves 1-5 for installing the plug-in units are newly added to the corner pieces, so that the corner pieces can be connected through the plug-in units, the installation of components for pin joint between containers is guaranteed, and the stacking safety of the containers is guaranteed.

Example two

Referring to fig. 3-6, the connecting structure of container corner fittings comprises two corner fittings and an insert 2 for connecting the two corner fittings according to the first embodiment. Two containers stacked up and down are stacked, and corner pieces at four corners of the two containers are aligned. The top surfaces of the upper and lower corner pieces are opposite and aligned. The right angle slots 1-4 of the two aligned corner pieces are aligned and form a vertically extending slot.

The insert 2 comprises a body portion 2-1. Specifically, the main body portion 2-1 is a cast iron plate extending vertically and having a thickness of 13 mm. The main body part 2-1 is provided with an inserting plate 2-2 which is respectively inserted with the pin connecting grooves 1-5 at the same side of the two corner pieces. The inserting plate 2-2 is a plate body communicated with the main body part 2-1 in thickness and is formed by processing a cast iron plate. The body part 2-1 of one of the inserts 2 has a male cannula 2-3 and the body part 2-1 of the other insert has a female cannula 2-4 staggered in longitudinal position with respect to the male cannula 2-3. The male cannula 2-3 and the female cannula 2-4 have vertical receptacles. The male cannula 2-3 and the female cannula 2-4 are metal tubes, and the main body part 2-1 is welded. Specifically, the main body part 2-1 of one of the inserts is provided with three female cannula 2-4 which are vertically distributed, a gap is formed between two adjacent female cannula 2-4, and the main body part 2-1 of the other insert is provided with the male cannula 2-3 which is in one-to-one correspondence with the gap. The main body part 2-1 and the inserting plate 2-2 are integrally constructed with the male cannula 2-3 or the female cannula 2-4 by welding.

The plug-in method of the plug-in 2 comprises the following steps: two inserting plates of the inserting piece with the female inserting pipes 2-4 are inserted into the pin joint grooves 1-5 on the right-angle surfaces on the same side of the two vertically arranged corner pieces, and the gap between the pin joint grooves 1-5 and the inserting plates 2-2 is 1 mm. The plug-in unit is inserted into the deepest position, and the female cannula 2-4 of the plug-in unit is positioned in the right-angle notch 1-4 and completely leaves the pin joint groove front of the other right-angle surface. And inserting the other two inserting plates with the male inserting tubes 2-3 into the pin connecting grooves on the right-angle surfaces at the two outer sides of the two corner pieces which are arranged up and down, wherein the gap between the pin connecting grooves and the inserting plates is 1 mm. When the opening between the male cannula 2-3 and the female cannula 2-4 of the plug-in part with the male cannula 2-3 corresponds to the opening, the plug-in part with the female cannula 2-4 is pulled out by a section until the male cannula 2-3 and the female cannula 2-4 are staggered and the vertical jacks are aligned.

A pin rod 3 is inserted into the exposed inserting pipe and the female inserting pipe from top to bottom, and the upper end of the pin rod 3 is provided with an end head part with the diameter larger than that of the pin rod. The end head part plays a role in inserting and limiting the pin rod 3. The two corner fittings hinged by the pin rod 3 form a 90-degree angle pin fitting to realize the connection of the upper corner fitting and the lower corner fitting, thereby realizing the connection between the upper container and the lower container. The connection mode has no locking force and has the main function of preventing the upper container and the lower container from toppling due to large relative displacement caused by external force.

The angle pin piece forming 90 degrees has a self-locking function that the pin piece can not be separated from the pin joint groove under the state that the pin rod is not pulled out.
