Linear slide rail with self-locking structure and self-locking unlocking method

The invention relates to a linear slide rail with a self-locking structure and a self-locking unlocking method. The linear slide rail comprises an outer layer slide rail, an inner layer sliding blockand a self-locking block; the self-locking block and the inner layer sliding block are riveted and fixed through rivets, the outer layer slide rail and the inner layer sliding block are hinged to twosides of a fixed structural part respectively, and the inner layer sliding block is assembled on the inner layer side of the outer layer slide rail in a clearance fit mode; and the non-connection sideof the outer layer slide rail is provided with a special-shaped structure, the self-locking block can be rotated in each movement, and the special-shaped structure of the self-locking block interferes in the structure of the outer layer sliding rail through rotation, so that the self-locking function is realized. On the premise of not influencing the integral structure of the linear slide rail, the self-locking reset funct
