[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7 The utility model provides a technical solution: a rubber sealing ring that is convenient for disassembly, assembly and replacement, comprising a first sealing layer 1, a second sealing layer 2 and a guide rod 3, wherein the second sealing layer 2 wraps the guide rod 3, a guide head 4 and an installation groove 5 are provided on the second sealing layer 2, the guide head 4 and the installation groove 5 are respectively located at the two ends of the second sealing layer 2, and the guide head 4 and the installation groove 5 are connected to each other by mortise and tenon joints, a positioning plate 6 is provided at one end of the first sealing layer 1, the first sealing layer 1 wraps the second sealing layer 2, and the end of the second sealing layer 2 close to the guide head 4 abuts against the positioning plate 6, the second sealing layer 2 is guided into the first sealing layer 1 by the guide head 4 on the second sealing layer 2, and the positioning plate 6 abuts against the second sealing layer 2, and secondly, under the support of the guide rod 3, the guide head 4 drives the first sealing layer 1 to enter the position where the sealing ring needs to be replaced, and then the two ends of the first sealing layer 1 and the second sealing layer 2 are plugged into each other, so as to realize the rapid disassembly, assembly and replacement of the rubber sealing ring;

[0031] The guide rod 3 is a thin galvanized steel wire, which supports the guide head 4 so that it can change direction when in use;

[0032] The cross-sections of the guide head 4 and the installation groove 5 are both conical, which facilitates the movement of the sealing ring during installation and also facilitates the mutual cooperation between the guide head 4 and the installation groove 5 during the installation of the sealing ring;
