Abstract
The utility model discloses a locking structure used for a period cycle life testbed of a constant speed drive shaft. The locking structure used for a period cycle life testbed of a constant speed drive shaft comprises a grip cylinder, a mounting rack, a guide sleeve, and a clamping arm. The grip cylinder comprises a center shaft, and the grip cylinder is fixed on a side of the mounting rack. The guide sleeve is on the other side of the mounting rack and is connected with the mounting rack. The guide sleeve is sleeved on the center shaft of the grip cylinder. A part of the clamping arm is in the guide sleeve. The clamping arm is connected with the center shaft of the grip cylinder. The lower part of the clamping arm is provided with a clamping boss. Through the grip cylinder driving the clamping arm and the clamping boss to move, when the locking structure used for a period cycle life testbed of a constant speed drive shaft operates, the grip cylinder provides great indentation forces, so that the contact between the clamping boss and a fixed object is very tight, thereby achieving a locking effect. The structure is high in locking strength, simple in structure, and is practical.
