Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.
With reference to Fig. 1-2, a kind of quick coupling device suitable on graden machine, including the first straight tube 1,2 and of outer sleeve
Second straight tube 7, the inside of the first straight tube 1 set third straight tube 9, and one end of third straight tube 9 is truncated cone-shaped structure, and third straight tube 9
Outer wall and the inner wall of the first straight tube 1 weld, be welded with the first retainer ring 5 on the outer wall of the first straight tube 1, the second straight tube 7 it is outer
It is welded with the second retainer ring 6 on wall, the first straight tube 1 is located at the inside of outer sleeve 2, and outer sleeve 2 is internally provided with the first rubber
Gasket 3, SW with outside ring 10 and spring 4, SW with outside ring 10 is between the first rubber gasket 3 and spring 4, bullet
For spring 4 close to the first retainer ring 5, one end of outer sleeve 2 is equipped with internal thread, and the second straight tube 7 is located at the inside of the first straight tube 1, and the
Two straight tubes 7 are sleeved on one end of 9 frustum cone structure of third straight tube, and outer sleeve 2 sets female side equipped with cored screw 8, empty
Heart screw 8 is equipped with the second rubber gasket.
Cored screw 8 is sleeved on the second straight tube 7, and cored screw 8 is threadedly coupled with outer sleeve 2, the first straight tube 1 and second
