Description

Locking mechanical claw structure that takes off for warehouse goods Technical Field The utility model relates to the technical field of mechanical claws, in particular to an anti-loosening mechanical claw structure for warehouse goods. Background In the field of warehouse logistics, the gripper is used as a core component of automatic handling equipment, and the clamping stability of the gripper directly influences the safety of cargo transportation. The traditional mechanical claw adopts a pure mechanical clamping structure, the clamping force adjustment depends on manual operation, and the problems of low adjustment precision, complex operation and the like exist. In addition, when the existing mechanical claw works for a long time or is subjected to vibration or load change, the cargo is easy to loosen due to damping of clamping force, and potential safety hazards exist. Therefore, it is necessary to provide a new anti-loosening mechanical claw structure for warehouse goods to solve the above technical problems. Disclosure of utility model In order to solve the technical problems, the utility model provides an anti-loosening mechanical claw structure for warehouse goods.
