[0018] 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 in 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.

[0019] See also Figure 1 and Figure 2 A spliced ​​rubber sealing ring in this embodiment includes a sealing ring 1, which is semicircular. Connectors for connecting the two sealing rings 1 are arranged at both ends of the sealing ring 1. The interior of the sealing ring 1 is an open structure and an expansion member is arranged inside. Wear-resistant parts for protecting the sealing ring 1 are arranged on both side surfaces of the sealing ring 1.

[0020] See also Figure 1 and Figure 2 In this embodiment, the connecting member includes a card slot opened on one end of the sealing ring 1, and a card block 2 is fixedly installed on the other end of the sealing ring 1. The size of the card block 2 is the same as that of the card slot, and a connecting groove 3 is opened on the top of the card slot.

[0021] By inserting the card block 2 into the connecting groove 3, the staff can splice the two sealing rings 1. After the two sealing rings 1 are spliced, glue is filled into the gap between the card block 2 and the card slot through the connecting groove 3, so that the card block 2 can be tightly connected with the card slot ring, allowing the staff to splice the sealing rings 1. When one of the sealing rings 1 is damaged, the staff does not need to replace the entire sealing ring 1, but only needs to replace the damaged part, saving unnecessary cost.

[0022] It should be noted that the glue described above is specially designed for rubber materials. Its main ingredients include tackifiers, stabilizers, polymers, etc. It can cure quickly and has good waterproof properties. It can solidify in a short time, is safe and non-toxic, and is particularly suitable for rapid bonding between rubber or plastic toys or crafts.

[0023] See also Figure 1 and Figure 2 In this embodiment, the expansion member includes an airbag 4 fixedly mounted on the inside of the sealing ring 1, one end of the airbag 4 is connected to a ventilation pipe 5, an air valve is fixedly mounted on the ventilation pipe 5, a connecting groove 6 is opened inside the sealing ring 1 and on the left side of the connecting groove 3, the diameter of the connecting groove 6 is the same as the diameter of the connecting groove 3, and the ventilation pipe 5 is located inside the connecting groove 6.

[0024] The staff fills the airbag 4 with gas through the ventilation pipe 5 to expand the airbag 4, which drives the volume of the sealing ring 1 to expand, so that the sealing ring 1 can increase its diameter to a certain extent, making the sealing ring 1 suitable for a variety of environments.

[0025] See also Figure 1 and Figure 2 In this embodiment, the top of the communicating groove 6 and the top of the connecting groove 3 are both provided with a fixing groove extending to the upper surface of the sealing ring 1 and a sealing member is provided inside the fixing groove.

[0026] The sealing member includes a fixing block 7 arranged on the bottom wall of the fixing groove, a handle is embedded on the upper surface of the fixing block 7, the top of the fixing block 7 is flush with the top of the sealing ring 1, and a sealing block 8 is fixedly installed on the lower surface of the fixing block 7.

[0027] See also Figure 2 and Figure 3 In this embodiment, the wear-resistant part includes a first pasting plate 9 fixedly installed on one side surface of the sealing ring 1, a wear-resistant pad 10 is provided on one side surface of the sealing ring 1, and a second pasting plate 11 is fixedly installed on the side surface of the wear-resistant pad 10 facing the first pasting plate 9, and the second pasting plate 11 is pasted to the first pasting plate 9.

[0028] The staff applies adhesive to the surface of the second adhesive plate 11 and the first adhesive plate 9, so that the second adhesive plate 11 can be connected to the first adhesive plate 9, and the wear-resistant pad 10 can be installed on the surface of the sealing ring 1, thereby protecting the sealing ring 1 and avoiding surface damage of the sealing ring 1 due to long-term mechanical wear, thereby extending the service life of the sealing ring 1.

[0029] The working principle of the above embodiment is as follows: by inserting the card block 2 into the interior of the connecting groove 3, the staff can splice the two sealing rings 1. After the two sealing rings 1 are spliced, glue is filled into the gap between the card block 2 and the card groove through the connecting groove 3, so that the card block 2 can be tightly connected with the card groove ring, so that the staff can splice the sealing rings 1. When one of the sealing rings 1 is damaged, the staff does not need to replace the sealing ring 1 as a whole, but only needs to replace the damaged part, thereby saving unnecessary cost consumption. When the sealing ring 1 is installed on the machine, gas is filled into the airbag 4 through the ventilation pipe 5, so that the airbag 4 expands, and the airbag 4 drives the volume of the sealing ring 1 to expand, so that the sealing ring 1 can increase its own diameter to a certain extent, so that the sealing ring 1 can drive the wear-resistant pad 10 to be in close contact with the inner wall of the machine, thereby protecting the surface of the sealing ring 1.
