Anti-falling building structure of escalator

The utility model relates to the technical field of escalators, and discloses an escalator anti-falling building structure which comprises a ground, the top of the ground is fixedly connected with a base, the top of the base is provided with a mounting mechanism, and the top of the mounting mechanism is fixedly connected with an assembling mechanism. The mounting mechanism comprises a mounting groove, the mounting groove is formed in the top of the base, and a mounting block is arranged on the inner side of the mounting groove. According to the anti-falling building structure for the escalator, by arranging the mounting mechanism, when the anti-falling building structure needs to be mounted, a mounting block is placed in a mounting groove, then threaded rods on the two sides are rotated, the threaded rods rotate to drive an adjusting plate to move upwards, the bottom end of a support moves upwards to push limiting blocks on the two sides into corresponding limiting grooves, and therefore mounting of the botto
