[0021] The sealing strip 3 is used to seal the gap between the inner ring and the outer ring of the main body 1. The sealing strip 3 can prevent external dust and other debris from leaking between the inner ring and the outer ring of the main body 1 during use, thereby extending the service life of the main body 1 while ensuring the working effect of the main body 1. When the device is used, the sealing strip 3 is installed on the installation groove of the main body 1. When the user installs the sealing strip 3, the user needs to cut the sealing strip 3 to a suitable length, which ensures the working effect of the sealing strip 3 and is convenient for the user to adjust the length of the sealing strip 3 according to actual conditions. When the user installs the sealing strip 3, the two ends of the sealing strip 3 can be connected together by cooperating with the connecting protrusion 5 and the connecting groove 51. The connection method at both ends of the sealing strip 3 makes it easy for the user to align the two ends of the sealing strip 3, avoiding misalignment when the user fixes the two ends of the sealing strip 3 together, ensuring the smoothness of the surface of the sealing strip 3 after the two ends of the sealing strip 3 are connected together, and ensuring the working effect of the sealing strip 3. When using the sealing strip 3, the user uses a machine to cut out connecting protrusions 5 and connecting grooves 51 at both ends of the sealing strip 3. The manufacturing method of the connecting protrusion 5 ensures the stability of the connection between the connecting protrusion 5 and the main body 1, and then ensures the stability of the cooperation between the connecting protrusion 5 and the connecting groove 51. The cooperation between the limiting groove 52 and the side wall protrusion of the connecting protrusion 5 plays a limiting role. The cooperation between the limiting groove 52 and the side wall protrusion of the connecting protrusion 5 The connection is ensured by the fact that after the connecting protrusion 5 is placed in the connecting groove 51, the top and bottom surfaces of the two ends of the sealing strip 3 are on the same plane, ensuring the surface flatness after the two ends of the sealing strip 3 are connected together. The adhesive 2 is used to stick the two ends of the sealing strip 3. When the user connects the two ends of the sealing strip 3 together, the adhesive 2 is applied to the side wall of the connecting groove 51, and then the connecting protrusion 5 is installed on the connecting groove 51. At this time, the connecting protrusion 5 and the connecting groove 51 are fixed together by the adhesive 2. The user can heat and press the matching position of the connecting protrusion 5 and the connecting groove 51 through a hot pressing device. After being heated by the hot pressing device, the adhesive 2 is completely fused with the connecting groove 51 and the connecting protrusion 5. At this time, the seal is The interface at the connection between the two ends of the strip 3 disappears, which ensures the stability of the two ends of the sealing strip 3 after being fixed together, avoids the failure of the fixation between the two ends of the sealing strip 3 due to the failure of the adhesive 2 during the use of the device, and ensures the stability and working effect of the sealing strip 3 during the use of the device. When applying the adhesive 2 to the connecting protrusion 5 and the connecting groove 51, the packaging shell 21 is removed from the adhesive 2. The shape of the packaging shell 21 ensures that the shape of the adhesive 2 stored inside the packaging shell 21 matches the shape of the connecting groove 51 and the limiting groove 52. When the user applies the adhesive 2 on the connecting groove 51 and the limiting groove 52, the user can place the adhesive 2 directly on the connecting groove 51, which improves the efficiency of the user in applying the adhesive 2.

[0022] Specifically, the connecting protrusion 5 and the connecting groove 51 are in a T-shape.

[0023] The shapes of the connecting protrusion 5 and the connecting groove 51 ensure that when the connecting protrusion 5 enters the connecting groove 51, the cooperation between the connecting protrusion 5 and the connecting groove 51 plays a limiting role, thereby preventing the cooperation between the connecting protrusion 5 and the connecting groove 51 from being released during the process of hot pressing the cooperation between the connecting protrusion 5 and the connecting groove 51 by the user, thereby ensuring the stability of the connection between the two ends of the sealing strip 3 during the hot pressing process and the strength of the two ends of the sealing strip 3 after being fixed together.

[0024] Specifically, a positioning tape 6 is adhered to the top surface of the sealing strip 3 .

The positioning tape 6 is adhered to the sealing strip 3. After the two ends of the sealing strip 3 are fixed together under the action of the hot pressing device, the fixing method of the positioning tape 6 facilitates the user to remove the positioning tape 6 from the sealing strip 3, thereby preventing the positioning tape 6 from detaching from the sealing strip 3 during use during installation, which would affect the use of the device.

[0026] Specifically, the packaging shell 21 is made of thermal insulation material.

[0027] The material of the packaging shell 21 ensures that the adhesive 2 will not be affected by the external environment during storage, ensuring that the adhesive 2 stored inside the packaging shell 21 is in a solid state, making it convenient for the user to apply the adhesive 2 and avoiding the user's efficiency in applying the adhesive 2 on the connecting protrusion 5 and the connecting groove 51 being affected by changes in external temperature.

[0028] Specifically, the packaging shell 21 is composed of a first shell 211 and a second shell 212 , and the first shell 211 and the second shell 212 are provided with matching grooves and protrusions.

[0029] The installation method of shell 1 211 and shell 2 212 is to separate shell 1 211 and shell 2 212 from the user, making it convenient for the user to use adhesive 2. A groove is provided on the side wall of shell 1 211, and a protrusion is provided on shell 2 212. The positions of the matching grooves and protrusions ensure that the user will not be hindered when holding shell 1 211 to apply adhesive 2 to the connecting groove 51, making it convenient for the user to apply adhesive 2.

[0030] Specifically, a groove is provided on the side wall of the end surface where the housing 1 211 and the housing 2 212 are matched.

[0031] The sidewall groove of the housing 1 211 provides a force application position for the user to separate the housing 1 211 and the housing 2 212 , making it convenient for the user to separate the housing 1 211 and the housing 2 212 .

[0032] Specifically, a protective cover 4 is installed on the bottom of the inner ring of the main body 1 by screws, and an annular groove matching the protective cover 4 is provided on the bottom surface of the outer ring of the main body 1, and the edge of the protective cover 4 is located inside the annular groove on the bottom surface of the outer ring of the main body 1.

[0033] The protective cover 4 can prevent external dust and other debris from entering the interior of the main body 1.
