[0002] A sealing ring is a protective accessory used to prevent liquid leakage and to prevent external residues or dust from entering various parts of mechanical equipment. It is an annular cover composed of one or more parts, fixed to one of the bearing rings or washers and in contact with or forming a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign object intrusion. A sealing ring is a rubber ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring. After the sealing ring is installed, it needs to be disassembled. When disassembling the sealing ring, a professional disassembly device is required.

[0003] In summary, traditional sealing ring removal devices can only remove sealing rings of a certain size. When removing multiple sealing rings of different sizes, multiple removal devices are required, which increases the cost. Therefore, there is a particular need for a sealing ring removal device.

A connecting block 204 is limited and snapped onto the inner ring surface of the mounting shell 203. A motor 205 is installed on the side surface of the connecting block 204. An eccentric wheel 206 is fixedly sleeved on the top of the output shaft of the motor 205. When it is necessary to use and disassemble the sealing ring, it is necessary to grasp the handle 7 and snap the plug-in flat head 202 onto the part that needs to be used. To remove the seal ring from its installation gap, motor 205 needs to be turned on. Once started, motor 205 will rotate the eccentric wheel 206 fixedly fitted to the top of its output shaft. This rotation of the eccentric wheel 206 will cause slight movement of the seal ring removal device assembly 1, vibrating the installed seal ring. Combined with the provided insert flat head 202, the snap-fit ​​seal ring can be removed. When removing seal rings of different sizes, the pull ring needs to be pulled. 6. Next, the piston plate 5 can be removed from the protective shell 4. Then, the different sized plug-in flat heads 202 stored in the storage plate 212 need to be removed and replaced. When replacement is needed, the snap-fit ​​block 207 needs to be pressed and then the plug-in flat head 202 needs to be pulled out. In this way, the plug-in flat head 202 can be removed from the collar 201. Then, the plug-in flat heads 202 of different sizes can be inserted into the collar 201. In this way, the sealing rings of different sizes can be used and disassembled efficiently.

[0024] Furthermore, a piston plate 5 is installed on the inner ring surface of the protective shell 4 for limiting the connection. The piston plate 5 is connected between the protective shell 4 and the sealing ring disassembly device connecting the main component 1. The piston plate 5, which is connected between the protective shell 4 and the sealing ring disassembly device connecting the main component 1, facilitates a stable connection between the piston plate 5 and the sealing ring disassembly device connecting the main component 1.

[0025] Furthermore, the motor 205 is connected to the mounting housing 203 via the connecting block 204, and the connecting block 204 is arranged around the motor 205 as the center point. The arrangement of the connecting block 204 around the motor 205 as the center point facilitates the stable installation of the motor 205 on the mounting housing 203.

[0026] Furthermore, the snap-fit ​​block 207 is connected to the plug-in flat head 202 via a reset spring 208, and the reset spring 208 and the plug-in flat head 202 are matched in size. The reset spring 207, which is matched in size to the plug-in flat head 202, facilitates a stable connection between the snap-fit ​​block 207 and the plug-in flat head 202.

[0027] Furthermore, the storage plate 212 has multiple storage openings 211 on its inner ring, and the storage openings 211 and the plug-in flat head 202 are structurally compatible. The storage openings 211 that are structurally compatible with the plug-in flat head 202 facilitate the use and storage of the multiple plug-in flat heads 202.

[0028] Furthermore, a pull ring 6 is fixedly connected to the side surface of the piston plate 5, and the pull ring 6 is connected between the piston plate 5 and the protective shell 4. The pull ring 6, which is provided to connect the piston plate 5 and the protective shell 4, facilitates the connection between the pull ring 6 and the protective shell 4.

[0029] Furthermore, the plug-in flat head 202 is limited and snapped onto the collar 201 by the snap-fit ​​block 207, and the plug-in flat head 202 and the plug-in opening 210 are matched in size. The plug-in flat head 202, which is matched in size with the plug-in opening 210, can facilitate the use of the plug-in opening 210 by snapping it in.

[0030] Working principle: When the sealing ring needs to be removed, grip handle 7 and engage the insert flat head 202 into the gap where the sealing ring needs to be removed. Turn on motor 205. After motor 205 starts, it drives the eccentric wheel 206 fixedly sleeved at the top of its output shaft to rotate. The rotating eccentric wheel 206 can make the sealing ring removal device connecting assembly 1 move slightly, thus vibrating the installed sealing ring. With the help of the insert flat head 202, the engaged sealing ring can be removed and used. When using and disassembling sealing rings of the same size, pull the pull ring 6 to remove the piston plate 5 from the protective shell 4. Then, remove and replace the different sized plug-in flat heads 202 stored in the storage plate 212. When replacement is needed, press the snap-fit ​​block 207 and then pull out the plug-in flat head 202 to remove it from the collar 201. Then, insert the different sized plug-in flat heads 202 into the collar 201. This allows for efficient use and disassembly of sealing rings of different sizes.
