Drawings
Fig. 1 is a schematic view of the overall structure provided by the present invention;
fig. 2 is a side sectional view provided by the present invention;
fig. 3 is an enlarged view of the a-portion structure in fig. 2 according to the present invention.
In the figure: the device comprises a sleeve 1, a first core rod 2, a second core rod 3, a U-shaped groove 4, a cylindrical pin 5, a key cap 6, a spring 7, a conical head 8, an O-shaped ring 9, a part 10 and an installation groove 11.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to the attached drawings 1-3, the utility model provides a quick installation device for an O-shaped ring 9, which comprises a sleeve 1, wherein an installation mechanism is arranged inside the sleeve 1, and the installation mechanism extends to the outer sides of the top and the bottom of the sleeve 1;
the mounting mechanism comprises a first core rod 2 and a second core rod 3, the second core rod 3 is sleeved on the outer side of the first core rod 2, the bottom end of the second core rod 3 extends to the inside of the sleeve 1, the bottom end of the first core rod 2 extends to the outside of the bottom of the second core rod 3, a round hole is arranged inside the first core rod 2, a U-shaped groove 4 is arranged inside the second core rod 3, a cylindrical pin 5 is embedded in the sleeve 1, the cylindrical pin 5 is positioned in the round hole and the U-shaped groove 4, a key cap 6 is arranged at the top end of the first core rod 2, a spring 7 is sleeved outside the first core rod 2, the bottom end of the sleeve 1 is fixedly connected with a conical head 8, an O-shaped ring 9 is sleeved outside the conical head 8, a part 10 is embedded in the bottom end of the second core rod 3, the bottom end of the part 10 extends to the outer side of the bottom of the second core rod 3, and a mounting groove 11 is formed in the surface of the part 10;
