[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and in the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it should not be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] A novel push rod, such as Figs. 1-3As shown, it comprises an I-shaped bent rod 1 and a core seat 2 arranged at both ends of the I-shaped bent rod 1, a groove 4 is arranged in the I-shaped bent rod 1, the I-shaped bent rod 1 and the core seat 2 are integrally formed, and the width of the middle part of both is greater than that of both ends. Such a structure can make the position of the middle part better disperse stress to both sides when external load acts on the thrust rod, thereby avoiding structural damage caused by stress concentration, and when subjected to bending load, the middle part has a larger moment of inertia, thereby having higher bending stiffness and being able to better resist bending deformation. As long as the middle part structure is not deformed, the effect on the operation of the thrust rod is small. Under the action of dynamic load, the structure will be subjected to periodic stress changes, and the design of the wide middle part can reduce the stress cycle times of the structure during the stress process, thereby reducing the risk of fatigue failure.

[0019] A connection reinforcing part 3 is arranged between the I-shaped bent rod 1 and the core seat 2, and the thickness of the connection reinforcing part 3 gradually decreases towards one end of the I-shaped bent rod 1, that is, the closer to the core seat 2, the greater the connection area. Therefore, the connection reinforcing part 3 has higher tensile strength and torque carrying capacity, which can effectively prevent the thrust rod from being broken or damaged between the I-shaped bent rod 1 and the core seat 2 during operation. The thickness gradually decreases instead of forming an end face at both ends of the groove 4. In addition to increasing the connection area, it can also avoid the stress concentration that easily occurs after the end face is formed, thereby further increasing the connection strength between the I-shaped bent rod 1 and the core seat 2.

[0020] A plurality of reinforcing ribs 5 are arranged in the groove 4, the reinforcing ribs 5 are arranged uniformly and connected to the two side walls of the groove 4 at both ends and are horizontal and perpendicular to the side walls of the groove 4. Therefore, under the action of the reinforcing ribs 5, the moment of inertia of the I-shaped bent rod 1 is increased, thereby improving its stiffness, making the I-shaped bent rod 1 more resistant to deformation, and the resistance to pressure or torque applied or generated on its side will be improved, thereby adapting to a higher load environment.

[0021] A side reinforcement arc edge 6 is arranged between the edge of the reinforcing rib 5 and the side wall of the groove 4, and the arc of the side reinforcement arc edge 6 is 60-90 degrees. The side reinforcement arc edge 6 can increase the connection area of the reinforcing rib 5 and the I-shaped bent rod 1 and increase the dispersion degree of stress at the connection, thereby increasing the strength. If the side reinforcement arc edge 6 is too small, it may cause stress concentration and increase the risk of stress at the connection, thereby reducing the connection strength. Therefore, setting a side reinforcement arc edge 6 of appropriate size can better increase the strength. A bottom reinforcement arc edge 7 is arranged between the reinforcing rib 5 and the bottom surface of the groove 4, and the arc of the bottom reinforcement arc edge 7 is 60-90 degrees. The bottom reinforcement arc edge 7 can more effectively disperse the stress generated at the connection between the reinforcing rib 5 and the bottom of the groove 4, thereby further increasing the strength.
