[0002] As an indispensable equipment in the field of engineering machinery, the performance and stability of the loader directly affect the efficiency and safety of the project. In the structural design of the loader, the articulation design of the frame is a key link. At present, the front and rear frames of my country's loaders adopt a direct articulation design. Therefore, when the rear frame rotates, there is no certain limit and buffering effect, which will cause the frame to be damaged due to excessive rotation, greatly reducing the service life of the equipment, and also greatly reducing the work progress. For this reason, a loader frame articulation structure is proposed. Utility Model Content

[0003] The purpose of the present utility model is to provide a loader frame articulation structure, by setting a rotating component, specifically when the rear frame rotates during work, it will drive gear two to rotate together, then gear one will also rotate together through the rotation of gear two, and support rod two will drive support rod one to have a certain ductility through the bearing limiting effect, thereby solving the problem that the loader is an indispensable equipment in the field of engineering machinery, and its performance and stability directly affect the efficiency and safety of the project. In the structural design of the loader, the articulation design of the frame is a key link. At present, the front frame and the rear frame of my country's loaders adopt a direct articulation design. Therefore, when the rear frame rotates, there is no certain limiting and buffering effect, which will cause the frame to be damaged due to excessive rotation, greatly reducing the service life of the equipment, and also greatly reducing the work progress.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The utility model is a loader frame articulation structure, including a main frame mechanism, the main frame mechanism includes a front frame, a rear frame is provided on the right side of the front frame, a rotating assembly is provided inside the front frame, a buffer assembly is provided on the top of the rotating assembly, and the rotating assembly includes a rotating shaft 1, the top and bottom of the outer surface of the rotating shaft 1 are fixedly connected to the top and bottom of the inside of the front frame, a gear 1 is provided inside the front frame, the inside of the gear 1 is rotatably connected to the outer surface of the rotating shaft 1, the outer surface of the gear 1 is meshed with a gear 2, and the top and bottom of the front and back sides of the gear 1 are provided with a support rod 2. When the rear frame rotates during work, it will drive the gear 2 to rotate together, and the gear 1 will also rotate together through the rotation of the gear 2. The support rod 2 will drive the support rod 1 to have a certain ductility through the effect of the bearing limit, which greatly improves the rotation arc of the rear frame.

[0006] Furthermore, there are four support rods 2, and the parts connected to the four support rods 2 are the same. The right side of the interior of the support rod 2 is rotatably connected to the support rod 1 through a pin shaft, and the right side of the interior of the support rod 1 is rotatably connected to the limit bracket through a pin shaft. The right side of the limit bracket is fixedly connected to the left side of the rear frame, and the left side of the rear frame is fixedly connected to two support plates, and the left sides of the two support plates are rotatably connected to the top and bottom of the outer surface of the rotating shaft 1. The interior of the gear 2 is rotatably connected to the rotating shaft 2, and the top and bottom of the outer surface of the rotating shaft 2 are fixedly connected to the corresponding side of the interior of the support plate. When the rear frame moves, it will drive the limit bracket to move together, and the movement of the support rod 1 through the limit bracket will drive the support rod 2 to move together, and the support rod 2 will drive the support rod 1 to a certain extent through the bearing limit effect.

[0007] Furthermore, a limit plate 1 is provided at the top and bottom of the gear 1, and the interiors of the two limit plates 1 are fixedly connected to the top and bottom of the outer surface of the rotating shaft 1. A limit plate 2 is provided at the top and bottom of the gear 2, and the interiors of the two limit plates 2 are fixedly connected to the top and bottom of the outer surface of the rotating shaft 2.

[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model sets a rotating assembly. Specifically, when the rear frame rotates during operation, it drives the gear 2 to rotate together. Then the gear 1 will also rotate together through the rotation of the gear 2. The support rod 2 will drive the support rod 1 to a certain extent through the bearing limit effect, which greatly improves the rotation arc of the rear frame, greatly improves the practicality of the equipment, avoids damage to the equipment caused by excessive rotation, and greatly improves the service life of the equipment.

[0012] 2. The utility model provides a buffer component. Specifically, the airbag cushion is squeezed by the spring when it is subjected to force. At the same time, the spring drives the airbag cushion to reset through the rebound force, thereby buffering the force generated by the second support rod to a certain extent, greatly reducing the damage to the front frame when the rear frame moves, greatly improving the service life of the equipment, and reducing the number of times the staff needs to repair and replace the vehicle, greatly reducing the workload of the staff, and also greatly improving the work progress.
