[0004] Existing corner fittings are all directly fixed on the container. When the container is transported by a vehicle, it is mostly fixedly connected to the vehicle cargo box by the corner fittings. When the vehicle brakes, due to the large inertia of the container, the corner fittings are subjected to great force during braking and are easily damaged and deformed. Therefore, the market urgently needs to develop a container corner fitting with a buffering function to help people solve the existing problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a container corner fitting with a buffering function, so as to solve the problem proposed in the above background technology that the existing corner fittings are all directly fixed on the container, and when the container is transported by a vehicle, most of them are fixedly connected to the vehicle cargo box by the corner fitting. When the vehicle brakes, due to the large inertia of the container, the corner fitting is subjected to great force during braking and is easily damaged and deformed.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a container corner fitting with a buffering function, comprising a corner fitting assembly, a buffer groove being provided on the corner fitting assembly, a damper assembly being fixedly connected to the middle of the front and rear end surfaces inside the buffer groove, the damper assembly comprising a damping cylinder end and a telescopic end, the telescopic end being inserted into the damping cylinder end, guide rods being fixedly connected to both sides of the middle part of the buffer groove, the front and rear sections of the guide rods being fixedly connected to a limiting tube, and a rectangular connecting piece being provided for limiting the middle part of the buffer groove.

[0009] Preferably, one end of the limiting tube is flush with one end of the adjacent damping cylinder end on one side, and the other end of the limiting tube exceeds the other end of the adjacent damping cylinder end on one side.

[0010] Preferably, the front and rear ends of the guide rod are fixedly connected with a second connecting plate, and the front and rear ends of the guide rod are fixedly connected between the inside of the buffer groove and the corner piece assembly by a plurality of second bolts.

During the entire buffering process, the damper assembly, guide rod, and rectangular connector work together to form an effective buffering system.

[0022] 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 the embodiments.

[0023] See also Figure 1-4 The utility model provides an embodiment: a container corner fitting with a buffering function, including a corner fitting assembly 1, a buffer groove 101 is provided on the corner fitting assembly 1, and a damper assembly 2 is fixedly connected to the middle of the front and rear end surfaces inside the buffer groove 101. The damper assembly 2 includes a damping cylinder end 201 and a telescopic end 203. The telescopic end 203 is inserted into the damping cylinder end 201. Guide rods 3 are fixedly connected to both sides of the middle part of the buffer groove 101, and the front and rear sections of the guide rod 3 are fixedly connected to the limiting tube 301. A rectangular connecting piece 4 is provided for limiting the middle part of the buffer groove 101.

[0024] Furthermore, a first connecting plate 202 is fixedly connected to the damping cylinder end 201, and the damper assembly 2 is fixedly connected to the corner piece assembly 1 inside the buffer groove 101 through multiple first bolts 205, so that the damper assembly 2 is stably fixed in the buffer groove 101, and at the same time facilitates the disassembly and maintenance of the damper assembly 2.

[0025] Furthermore, one end of the telescopic end 203 extends out of the interior of the damping cylinder end 201 and is fixedly connected to a push plate 204. The push plates 204 on the telescopic ends 203 of the front and rear damper assemblies 2 are respectively fitted with the middle parts of the front and rear end surfaces of the rectangular connector 4. When the rectangular connector 4 slides back and forth along the buffer groove 101, the inertia of the forward and backward movement of the rectangular connector 4 is buffered and absorbed by the two damper assemblies 2.

[0026] Furthermore, one end of the limiting tube 301 is flush with one end of the adjacent damping cylinder end 201 on one side, and the other end of the limiting tube 301 exceeds the other end of the adjacent damping cylinder end 201 on one side. When the inertia of the rectangular connecting member 4 moving forward and backward is large, the telescopic end 203 is gradually retracted into the damping cylinder end 201, and the degree of forward and backward movement of the rectangular connecting member 4 is limited by the limiting tube 301 to prevent the rectangular connecting member 4 from moving too much and directly hitting the damping cylinder end 201, causing damage to the damper assembly 2.

[0027] Furthermore, the front and rear ends of the guide rod 3 are fixedly connected with a second connecting plate 302, and the front and rear ends of the guide rod 3 are fixedly connected between the inside of the buffer groove 101 and the corner piece assembly 1 by multiple second bolts 303, so that the guide rod 3 is stably fixed inside the buffer groove 101, and the guide rod 3 is easy to disassemble.

[0028] Furthermore, circular through holes 401 are provided on both sides of the middle part of the rectangular connector 4. The upper end of the rectangular connector 4 extends out of the upper end surface of the corner fitting assembly 1 and is fixedly connected to the end corner of the container. After the upper end of the rectangular connector 4 extends out of the upper end surface of the corner fitting assembly 1, two lifting through holes 402 are provided. The lifting through holes 402 facilitate the lifting and connection of the container. When the container moves forward and backward due to vehicle braking, it drives the rectangular connector 4 to move forward and backward in the buffer groove 101, and then the inertia of the forward and backward movement of the rectangular connector 4 is buffered and absorbed by the damper assembly 2.

[0029] Furthermore, the middle portions of the two guide rods 3 respectively pass through the two circular through holes 401 on the rectangular connector 4 , and the movement of the rectangular connector 4 is guided by the guide rods 3 , while the rectangular connector 4 is restricted from moving within the buffer groove 101 .

[0030] Working Principle: During use, when a container is transported by a vehicle, especially when the vehicle is braking or making an emergency stop, the container has a large inertia, which generates a forward and backward movement force. This movement force is first transmitted through the end corners of the container to the rectangular connector 4 fixed to it. The rectangular connector 4 serves as a key transmission component, and its upper and lower ends are respectively connected to the end corners of the container and the buffer groove 101 inside the corner piece assembly 1. When the container moves forward and backward, the rectangular connector 4 slides along the guide rod 3 set inside the buffer groove 101. The design of the guide rod 3 not only provides a stable guide for the movement of the rectangular connector 4, but also limits the range of movement of the rectangular connector 4 through the limit tube 301 on it, preventing it from damaging the damper assembly 2 or other components due to excessive movement. During the forward and backward movement of the rectangular connector 4, its front and rear end surfaces will respectively push the push plates 204 in the two damper assemblies 2. The push plates 204 are connected to the telescopic end 203 of the damper assembly 2, and the telescopic end 203 is inserted into the damper cylinder end 201. As the rectangular connector 4 moves, the telescopic end 203 telescopes within the damping cylinder end 201. The damping material or mechanism within the damper assembly 2 cushions and absorbs the inertia of the rectangular connector 4's forward and backward movement, thereby reducing the impact force on the corner fitting assembly 1 and preventing damage or deformation caused by excessive force. Throughout the entire buffering process, the damper assembly 2, guide rod 3, and rectangular connector 4 work together to form an effective buffering system. This system not only improves the stability and durability of the container corner fittings during transportation, but also significantly reduces the risk of container damage caused by vehicle braking and other operations, providing safer and more reliable protection for cargo transportation.
