Drawings

Fig. 1 is a schematic view of the utility model when the pin shaft is not installed.

Fig. 2 is a schematic view of the present invention in assembly use.

In the figure:

1. the structure comprises a dragging plate pipe, 11, a hollow hole, 12, a baffle, 2, a bearing, 21, a baffle, 3, a mounting hole, 5, a pin shaft, 51, a blocking plate, 52, a large-diameter shaft section, 53, a small-diameter shaft section, 6 and a bolt hole.

Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1 and 2, the utility model discloses a planker abrasionproof pivot is fixed in rack-mount hole 3, including planker pipe 1, bearing 2 and round pin axle 5, planker pipe 1 is the hollow tube, and bearing 2 is built-in at planker pipe 1 both ends, and round pin axle 5 passes mounting hole 3 and stretches into bearing 2 in, bearing 2 and round pin axle 5 fixed connection. The pin shaft 5 is in interference fit with the bearing 2, and the bearing 2 is sleeved on the pin shaft 5.

Specifically, a hollow hole 11 is arranged in the carriage pipe 1, steps are arranged at two ends of the hollow hole 11, and the bearing 2 is arranged in the steps. The step includes step face 12, and the every end of towing plate pipe 1 all is equipped with a pair of bearing 2, and the structure is more firm, rotates more smoothly. One side edge of the pair of bearings 2 is abutted against the step surface 12, the other side edge is abutted against the baffle plate 21, and the baffle plate 21 is clamped at the end part of the hollow hole 11 of the drag plate pipe 1.

The pin shaft 5 is a step shaft and comprises a large-diameter shaft section 53 and a small-diameter shaft section 52 which are connected, and the small-diameter shaft section 52 extends into the bearing 2 and is matched with the bearing 2; the large-diameter shaft section 52 is fitted to the mounting hole 3. The one end that major diameter shaft section 52 kept away from minor diameter shaft section 53 is the free end, still sets up closure plate 51 on the free end, and closure plate 51 covers mounting hole 3 port, restriction round pin 5 axial displacement. The large-diameter shaft section 52 is fixedly connected with the mounting hole 3 through a bolt. The mounting holes 3 and the large-diameter shaft section 52 are provided with corresponding bolt holes 6, and bolts can be inserted into the bolt holes 6 to fix the pin shafts 5.

When the carriage swings up and down, the carriage pipe 1 rotates, and the carriage pipe 1 rotates around the pin shaft 5 with the help of the bearing 2, so that the rotation is smoother. The pin shaft 5 is fixed by the combination of the blocking plate 51 and the pin, the pin shaft 5 is kept still in the mounting hole 3, the abrasion problem can not be caused, the service life of the bearing 2 is very long, the bearing 2 is arranged in the carriage pipe 1, the bearing is not easily damaged and interfered by the external environment, the replacement and the maintenance are generally not needed, and the maintenance cost is low.

The above description is the preferred embodiment of the present invention, and for those skilled in the art, modifications of the various equivalent forms of the present invention are within the scope of the appended claims of the present application without departing from the principle of the present invention.
