Specific embodiment
Below in conjunction with attached drawing detailed description of the present invention embodiment.
It as depicted in figs. 1 and 2, is the structural schematic diagram of crossbeam assembly involved in this embodiment, crossbeam assembly includes
The main body of cross-beam A of one section U-shaped and hinge base B set on crossbeam outer bottom,
The structure of the present embodiment includes bottom plate 1, positioning plate 2, locating rod 3 and positioning pin 6, and the positioning plate 2 has two pieces, and two
The big plane of positioning plate 2 is just opposite, is set on bottom plate 1 in parallel, the locating rod 3 passes perpendicularly through two positioning plates 2, to on crossbeam
Hinge base B positioned, the positioning pin 6 be set to bottom plate 1 on, be located at 3 side of locating rod, to on crossbeam
Hole C is positioned.
In the present embodiment, two positioning pins, 6 circle center line connecting is parallel to locating rod, when crossbeam hinge base B is set in positioning
When on bar 3, the location hole C on crossbeam can cooperate with positioning pin 6.
In the present embodiment, the positioning pin 6 is stepped shaft structure, and bigger diameter end 9 is connect with bottom plate 1, and miner diameter end 8 is spiral shell
Rasp bar is arranged with nut 7 on the threaded rod.
In the present embodiment, the distance between the 6 major diameter shaft part upper surface of positioning pin and bottom plate 1 are equal to the circle of locating rod 3
The distance between the heart and bottom plate 1.
In the present embodiment, 2 upper end of positioning plate is equipped with a lantern ring 4, and the lantern ring 4 on two positioning plates 2 is coaxially disposed, institute
Locating rod 3 is stated in lantern ring 4.Wherein lantern ring 4 can be set in 2 upper end of positioning plate on the angle of 6 side of positioning pin, such as scheme
