Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of trailer combination formula rotary hinges, including upper rotary hinges A2, upper rotary hinges B4, lower rotary shaft
Hinge C6 and lower rotary shaft hinge D7, the cross section of described upper rotary hinges A2 is " J " shaped, and it is fixed on vehicle breast board 1 upper end,
Described upper rotary hinges B4 is provided with rotating shaft 3, and it is fixed on column 5 upper end, and upper rotary hinges A2 coordinates with upper rotating shaft 3
Connect；Described lower rotary shaft hinge C6 cross section, in " C " shape, is fixed on vehicle breast board 1 lower end, on described lower rotary shaft hinge D7
Being provided with lower rotary shaft 8, it is fixed on column 5 lower end, and described lower rotary shaft 8 one end is provided with anticreep boss, lower rotary shaft hinge C6 with under
Rotating shaft 8 is connected.
Operation principle of the present utility model: the structure of upper rotary hinges A2 and lower rotary shaft hinge C6 is according to the difference of stressing conditions
Design, the cross section of upper rotary hinges A2 is " J " shaped, and lower rotary shaft hinge C6 cross section is in " C " shape, and the upper rotating shaft of " J " shape is closed
Page A2 catches on rotating shaft 3, and " C " shape lower rotary shaft hinge C6 holds lower rotary shaft 8, and is fastened by the lower rotary shaft 8 of band boss,
Thus reach the balance of power.It is simple that structure of the present utility model has novel structure, the advantage of easy installing/dismounting, and in road conditions
The disengaging of lower rotary shaft hinge C6 can be effectively prevented in the case of bad.
