Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, a trailer with regulatory function, including trailer main body 1, four corners of trailer main body 1 upper surface all are fixed with stand 2, stand 2 is cylindrical cavity structure, the through-hole has been seted up at stand 2's top, the through-hole internalization is provided with movable rod 3, four movable rod 3's top is fixed with roof 4 jointly, movable rod 3's bottom is provided with movable block 5, the cover is equipped with spring 6 on the movable rod 3, and spring 6 is located between movable block 5 and the 2 roof of stand, four corners of roof 4 lower surfaces all are fixed with push pedal 7, push pedal 7's perpendicular cross-section is the right angled triangle structure.

The welding has the horizontal pole 8 between two stands 2 that lie in same one side, and the rectangle hole 9 has been seted up to the symmetry on the horizontal pole 8, and sliding connection has slider 10 in the rectangle hole 9, and the one end of slider 10 is fixed with bracing piece 11, and slider 10 is T style of calligraphy structure.

Pulley 12 is installed on the top of bracing piece 11, four pulley 12 contact with four push pedal 7 respectively, symmetrical welding has fixed block 13 on the lateral wall of horizontal pole 8, set up threaded hole on the bracing piece 11, threaded hole female connection has screw rod 14, the length of screw rod 14 is greater than the length of rectangular hole 9, and the one end that two screw rods 14 kept away from mutually rotates respectively and installs on two fixed blocks 13, double-shaft motor 15 is installed to the intermediate position of horizontal pole 8, the both ends output shaft of double-shaft motor 15 is connected with two screw rod 14 transmissions respectively.
