[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a detachable rubber sealing ring includes a plastic ring 1 and a fixed outer ring 5. A clamping hole 2 is provided at the disconnection portion of the plastic ring 1, and a clamping block 3 is provided in the clamping hole 2. The other end of the plastic ring 1 is connected to a special-shaped plug-in block 4. The clamping hole 2 and the clamping block 3 are both arc-shaped, and the plastic ring 1 and the clamping block 3 are integrated. The special-shaped plug-in block 4 is plugged into the clamping hole 2, and the special-shaped plug-in block 4 and the clamping block 3 are tightly fitted. The fixed outer ring 5 is arranged on the outside of the plastic ring 1, and the plastic ring 1 is provided with a clamping hole 2. A fixed inner ring 6 is arranged on the inner side of the ring 1, and the fixed inner ring 6 includes an elastomer 601, a reinforcing steel wire 602, a silicone heat-resistant coating 603 and a wear-resistant layer 604, and the reinforcing steel wire 602 is nested in the elastomer 601, the inner surface of the elastomer 601 is arranged with a silicone heat-resistant coating 603, and the other side of the silicone heat-resistant coating 603 is arranged with a wear-resistant layer 604, three reinforcing steel wires 602 are arranged, and the reinforcing steel wires 602 are in an arc shape.

[0023] The specific operation is as follows: the plastic ring 1 has the ability to deform, and the special-shaped plug block 4 at one end of the plastic ring 1 is inserted into the clamping hole 2, and the special-shaped plug block 4 and the clamping block 3 are clamped together to connect the plastic ring 1 end to end, so as to generate an extrusion force on the fixed inner ring 6, the movable inner ring one 8, and the movable inner ring two 10, so that the gap at the fracture of the fixed inner ring 6, the movable inner ring one 8, and the movable inner ring two 10 is reduced, thereby ensuring the sealing effect of the rubber sealing ring.

[0024] like Figure 1 As shown, an anti-slipping tooth 7 is arranged in the groove on the inner side of the fixed inner ring 6, and a movable inner ring 8 is fixed to the side of the anti-slipping tooth 7 close to the center of the fixed inner ring 6, an anti-slipping tooth 2 9 is arranged in the groove on the inner side of the movable inner ring 8, and a movable inner ring 2 10 is fixed to the side of the anti-slipping tooth 29 close to the center of the fixed inner ring 6, the inner diameters of the fixed inner ring 6, the movable inner ring 1 8 and the movable inner ring 2 10 decrease successively, and the fixed outer ring 5, the fixed inner ring 6, the movable inner ring 1 8 and the movable inner ring 2 10 are coaxially arranged, three anti-slipping teeth 1 7 and three anti-slipping teeth 2 9 are each arranged, and the anti-slipping teeth 2 9 are equidistantly distributed along the inner surface of the movable inner ring 8.

[0025] The specific operation is as follows: the movable inner ring 1 8 and the movable inner ring 2 10 are initially in the shape of an "I", and are in a circular ring shape after being bent. At this time, the movable inner ring 1 8 is clamped with the fixed inner ring 6 through the anti-slip teeth 1 7, and the movable inner ring 2 10 is clamped with the movable inner ring 1 8 through the anti-slip teeth 2 9. The elastic recovery effect is used to make the movable inner ring 1 8 and the movable inner ring 2 10 fit tightly to ensure the sealing. At the same time, the fractures of the fixed inner ring 6, the movable inner ring 1 8, and the movable inner ring 2 10 are staggered to ensure the structural strength.

[0026] In summary, when the detachable rubber sealing ring is used, firstly, three reinforcing steel wires 602 are nested in the elastic body 601, which improves the strength and toughness of the fixed inner ring 6, and the organic silicon heat-resistant coating 603 and the wear-resistant layer 604 make the fixed inner ring 6 have heat-resistant and wear-resistant properties, slowing down the aging speed, and the fixed outer ring 5, the movable inner ring 1 8, and the movable inner ring 2 10 are made of the same material as the fixed inner ring 6;

[0027] The plastic ring 1 has the ability to deform. When used in mechanical equipment, the special-shaped plug-in block 4 at one end of the plastic ring 1 can be inserted into the clamping hole 2, and the special-shaped plug-in block 4 and the clamping block 3 are clamped together to connect the plastic ring 1 end to end to form a closed circular structure.

[0028] Since the movable inner ring 1 8 and the movable inner ring 2 10 are initially in the shape of a letter "I", and are in the shape of a ring after being bent, the anti-slipping teeth 1 7 on the outer surface of the movable inner ring 1 8 are inserted into the groove on the inner side of the fixed inner ring 6, and the anti-slipping teeth 2 9 on the outer surface of the movable inner ring 2 10 are inserted into the groove on the inner side of the movable inner ring 1 8. The elastic recovery effect can make the movable inner ring 1 8 and the movable inner ring 2 10 fit tightly in the plastic ring 1 to ensure the sealing performance. At the same time, the fractures of the fixed inner ring 6, the movable inner ring 1 8, and the movable inner ring 2 10 are all staggered, which further ensures the structural strength.

[0029] Since the fixed outer ring 5, the plastic ring 1, the fixed inner ring 6, the movable inner ring 1 8 and the movable inner ring 2 10 are all designed with fractures, the defect that the whole equipment needs to be disassembled when the existing rubber sealing ring is damaged is overcome, and it is convenient to change the inner diameter according to the installation environment on the mechanical equipment, thereby solving the problem of difficult selection of rubber sealing rings.

[0030] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
