1. The automobile ball hitch is designed especially for hitching gooseneck trailers. It consists of a supporting frame secured to the vehicle chassis and equipped with a vertical guide with blocking openings and the body of the ball hitch with a blocking opening, as well as of a blocking bolt. It is characterised in that the blocking bolt (15) has a transversal grip (16) and a pressing spring (17). The bolt slides in the longitudinal recess (12) in the slide (11), which is secured to the vertical guide (2) of the body (3) of the ball hitch, so that the axis of the blocking bolt (15) coincides with the axes of the opposite blocking openings in the vertical guide (2) of the body (3) of the ball hitch. The compressed spring (10) is secured under the body (3) of the ball hitch with the blocking openings (6) and (7), which slides inside the bottom part of the guide. |
