Technical Field
[0001] The utility model relates to the technical field of robot dogs, in particular to an anti-skid robot leg of a robot dog. Background Art
[0002] The robot dog is an element assisted by artificial intelligence. After being equipped with accessories such as robotic arms and transport boxes, it can be used to control all smart homes, do housework, pick up express deliveries, provide companionship, and provide security. There is a computer installed inside the robot dog that can adjust its moving posture according to changes in the environment. It can move along a pre-set simple route on its own, or it can be remotely controlled.
[0003] However, when the existing anti-skid robot legs of the robot dog are used, an anti-skid structure is usually installed at the bottom of the robot dog's robot legs, and the anti-skid structure is fixed with screws. When the robot dog moves, the anti-skid structure on the robot leg will be rubbed. After long-term use, the anti-skid structure on the robot leg will be damaged, and the staff needs to disassemble and replace it. However, when disassembling the anti-skid structure on the robot leg, it is necessary to use tools to disassemble the screws and other structures on the robot leg. The operation steps are cumbersome, which has a certain impact on the use of the robot dog. Therefore, an anti-skid robot leg for a robot dog is provided. Utility Model Content

[0008] Specifically, a rubber sheet for increasing the friction force on the limit block A is fixed by screws on the inner sides of the fixing frame and the fixing block.
[0009] By adopting the above technical solution, when the fixing frame and the fixing block clamp the limit block A, the rubber sheet in the fixing frame and the fixing block increases the friction force on the surface of the limit block A, thereby improving the stability of clamping the limit block A.
