[0019] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0020] Such as Figures 1-4As shown in the figure, a replaceable combined seal provided by an embodiment of the present utility model includes a basic seal 4 and a replaceable seal 6. The basic seal 4 is fixedly installed, and the replaceable seal 6 is slidably installed with the basic seal 4. An integrally formed extended connecting portion 5 is provided on an outer wall of one side of the basic seal 4, a clamping groove 9 is provided on an outer wall of one side of the basic seal 4, and a tenon 7 inserted into the clamping groove 9 is provided on an outer wall of one side of the replaceable seal 6.

[0021] Specifically, in this embodiment, it includes a basic seal 4 and a replaceable seal 6. The basic seal 4 and the replaceable seal 6 are of a slidable installation structure, which is convenient for disassembly and replacement. At the same time, the basic seal 4 and the replaceable seal 6 are made of dense rubber, which has relatively high hardness and strength, good wear resistance, compressive performance and anti-aging performance, and a long service life. The basic seal 4 is fixedly installed, and the replaceable seal 6 is slidably installed with the basic seal 4. An integrally formed extended connecting portion 5 is provided on an outer wall of one side of the basic seal 4, a clamping groove 9 is provided on an outer wall of one side of the basic seal 4, and a tenon 7 inserted into the clamping groove 9 is provided on an outer wall of one side of the replaceable seal 6.
