[0015] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will combine the specific embodiments of the present application and the corresponding drawings to clearly and completely describe the technical scheme of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.

[0016] As Figures 1 to 2 shown, the working device connecting rod with large-arc reinforcing ribs of the present application comprises a left side plate of rod body 1, a right side plate of rod body 2, a first hinge table 3, a second hinge table 4, a third hinge table 5 and a reinforcing rib 6. The first hinge table 3 is arranged at the front end of the left side plate of rod body 1 and the right side plate of rod body 2, the second hinge table 4 is arranged at the rear end of the left side plate of rod body 1, the third hinge table 5 is arranged at the rear end of the right side plate of rod body 2, and the reinforcing rib 6 is arranged between the left side plate of rod body 1 and the right side plate of rod body 2.

[0017] Further, in the working device connecting rod with large-arc reinforcing ribs of the present application, the reinforcing rib 6 is arranged in an arc shape, the front end of the reinforcing rib 6 is welded with the first hinge table 3, and the two sides of the reinforcing rib 6 are welded with the left side plate of rod body 1 and the right side plate of rod body 2 respectively. Thus, the connection strength of the left side plate of rod body 1 and the right side plate of rod body 2 is effectively improved by the arrangement of the reinforcing rib 6. The reinforcing rib 6 is arranged in an arc shape, so that the reinforcing rib 6 has sufficient connection length, thereby further strengthening the connection strength and ensuring the force bearing capacity of the connecting rod.

[0018] Further, in the working device connecting rod with large-arc reinforcing rib of the utility model, the middle part of the reinforcing rib 6 is provided with a weight-reducing hole 61 in the shape of a long round hole, so that the overall weight of the connecting rod is effectively reduced without affecting the reinforcing effect of the reinforcing rib 6.

[0019] Further, in the working device connecting rod with large-arc reinforcing rib of the utility model, the second hinge base 4 and the third hinge base 5 are coaxial.

[0020] Specifically, the first hinge base 3 is connected with the oil cylinder, the second hinge base 4 and the third hinge base 5 are connected with the bucket, and in the process of driving the bucket to pull up or push down by the oil cylinder, the length of the reinforcing rib 6 is extended by connecting the reinforcing rib 6 in the shape of an arc with the left side plate 1 and the right side plate 2 of the rod body, so that the reinforcing effect is improved, and the weight-reducing hole 61 in the middle part of the reinforcing rib 6 is in the shape of a long round hole, so that the overall weight of the connecting rod is effectively reduced without affecting the reinforcing effect of the reinforcing rib 6.
