Abstract

This application discloses a technical field relating to testing the luggage compartment doors of buses. A testing fixture for the luggage compartment doors of buses includes: two positioning plates, respectively fixedly installed on opposite sides of a door frame; two positioning seats, each abutting the surface of one of the positioning plates; a connecting rod, installed at any vertical position along the door frame and sliding horizontally on the positioning plates; a limiting post, passing through the two positioning seats and rotatably installed on them, with limiting rods distributed circumferentially on the end face of the limiting post, and a spacing between adjacent limiting rods for horizontal insertion of the connecting rod; the limiting rods contacting the walls of the connecting rods; and a reinforcing assembly installed on the limiting post for fixing the connecting rods. This application can flexibly adapt to different door frames and extends the overall service life.
