[0017] like Figure 1 and Figure 2 The utility model provides a floating pin shaft anti-sequential movement device, comprising a female ear plate 1 and a male ear plate 2 respectively fixed to the two ends of the buoyancy box, a slot for horizontal insertion of the male ear plate 2 is provided in the middle of the female ear plate 1, the female ear plate 1 and the male ear plate 2 are hinged by a pin shaft 3, one end of the pin shaft 3 is provided with a radial protrusion, and one end of the pin shaft 3 passing through the female ear plate 1 is sleeved with a stop ring 5, and the outer diameter of the stop ring 5 is larger than the inner diameter of the pin hole provided on the female ear plate 1.
[0018] A radial protrusion is welded on one end of the pin shaft 3. After the male ear plate 2 is inserted into the female ear plate 1, ensure that the pin holes of the male ear plate 2 and the female ear plate 1 are aligned. Then, the pin shaft 3 is inserted into the pin holes of the female ear plate 1 and the male ear plate 2, and the radial protrusion end wall of the pin shaft 3 is close to the end wall of the female ear plate 1. At this time, the annular groove of the pin shaft 3 for the stop ring 5 to be inserted is exposed from the female ear plate 1. The stop ring 5 is similar to a retaining ring structure, in an annular shape, with a notch at one section, and circular holes are provided at both ends of the notch. Use retaining ring pliers to insert into the circular holes at both ends of the stop ring 5 to open the stop ring 5, and then the stop ring 5 is clamped into the annular groove to achieve the installation of the stop ring 5.
[0019] like Figure 2As shown, in order to further improve the stability of the axial limit of the pin shaft 3, the outer peripheral wall of the end of the pin shaft 3 away from the axial protrusion is threadedly connected with a limit bolt 6, which is distributed at equal angles around the axis of the pin shaft 3 and is located below the stop ring 5.
[0020] Three threaded holes are provided on the outer end wall of the pin shaft 3 , and three limiting bolts 6 are connected through the three threaded holes, so that the pin shaft 3 is limited by the limiting bolts 6 .
[0021] like Figure 2 As shown, in order to prevent the shaft pin 3 from axially shaking and colliding, resulting in loosening of the stop ring 5, the radial protruding end of the shaft pin 3 is fixedly connected with a connecting ring 4, and the stop ring 5 is in contact with the end wall of the female ear plate 1.
[0022] like Figure 3 As shown. A pair of mounting plates 7 are vertically fixed on the separated outer walls of the female ear plate 1, and the mounting plates 7 are located on both sides of the pin shaft 3. The opposite side walls of the mounting plates 7 are connected with limit springs 10, one end of the limit spring 10 is fixed on the mounting plate 7, and the other end is connected to the connecting ring 4. The limit spring 10 applies a downward elastic force to the top of the pin shaft 3 to prevent the pin shaft 3 from loosening.
[0023] like Figure 1 and Figure 2 As shown. Pairs of mounting plates 7 are vertically fixed on the separated outer walls of the female ear plate 1. The mounting plates 7 are located on both sides of the pin shaft 3. The pair of mounting plates 7 are fixedly connected by two limiting bolts 8 through nuts.
