Abstract

[0002] Pneumatic components are components that perform work by using the force generated by the pressure or expansion of gas. They are machine parts that convert the elastic energy of compressed air into kinetic energy. In actual production work, the most common pneumatic components are cylinders and pneumatic motors.
[0003] The air pipe sealing mechanism is a mechanism used to seal the air inlet of pneumatic components and the air pipe. Usually, one end of the air pipe is screwed into the installation port, and the sealing performance of the air pipe connection is improved by the sealing gasket inside the installation port.
[0004] However, achieving a seal solely by squeezing the sealing ring results in a simplistic sealing structure. If the sealing ring ages, it can easily lead to a failure to seal properly. Therefore, to address these issues, a pipe sealing mechanism for pneumatic components is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-5 This utility model provides a duct sealing mechanism for pneumatic components, including a pneumatic component body 1 and a duct body 2; a connector 3 is fixedly disposed on the pneumatic component body 1, and an airtight mechanism is provided on the connector 3. The airtight mechanism, in cooperation with the duct connection mechanism, connects and seals the connector 3 with the airtight connector 8, thereby improving the sealing performance between the duct and the pneumatic component. The airtight mechanism includes an inner tube 4 and an outer tube 5 fixedly disposed on the connector 3, the inner tube 4 and the outer tube 5 being coaxially arranged, and an annular groove is formed on the connector 3. 6. Multiple screw-fit slots 7 are evenly provided on the outer tube 5. An airtight connector 8 is fixedly provided at the end of the air tube body 2. An air tube connection mechanism is provided on the airtight connector 8. The air tube connection mechanism is adapted to the airtight mechanism to connect and seal the connector 3 with the airtight connector 8, thereby improving the sealing performance between the air tube and the pneumatic component. An auxiliary sealing mechanism is detachably provided on the connector 3 and the airtight connector 8 after connection. The outer tube 10 after the auxiliary sealing mechanism is connected is sealed to the connector 3, thereby improving the sealing performance between the air tube and the pneumatic component.
[0027] Furthermore, such as Figure 3 As shown, the annular groove 6 is located between the inner pipe 4 and the outer pipe 5. When the inner clamping tube 9 is inserted between the inner pipe 4 and the outer pipe 5, the airtight gasket 11 at the end of the inner clamping tube 9 is engaged in the annular groove 6, thereby improving the sealing performance of the connection.
[0028] Furthermore, such as Figure 1 and Figure 4 As shown, the air pipe connection mechanism includes an inner clamping tube 9 and an outer clamping tube 10 fixedly mounted on the airtight connector 8. An airtight gasket 11 is fixedly mounted at the end of the inner clamping tube 9 and is inserted into the annular groove 6. Multiple screw-on clamps 12 are evenly arranged on the outer side of the inner clamping tube 9, and the corresponding screw-on clamps 12 are adapted to the screw-on grooves 7. A set of inner sealing rings 13 are fixedly mounted parallel to the inner wall of the outer clamping tube 10 and are engaged with the outer side of the outer pipe 5. Through the structural design of the air pipe connection mechanism and in conjunction with the use of the airtight mechanism, the connector 3 and the airtight connector 8 are connected and sealed, thereby improving the sealing performance between the air pipe and the pneumatic components.
[0029] Furthermore, such as Figure 1 As shown, the end of the connected outer clamp tube 10 fits into the connector 3. The outer side of the outer clamp tube 10 and the outer side of the connector 3 are on the same annular surface. Side grooves 14 are respectively provided on the outer side of the outer clamp tube 10 and the connector 3. With this structure, it is easy to smoothly put the sealing sleeve 15 on the outer side of the connected outer clamp tube 10 and the connector 3, thereby improving the sealing performance of the connection.
[0030] Furthermore, such as Figure 1 and Figure 5 As shown, the auxiliary sealing mechanism includes a sealing sleeve 15 detachably disposed on the outside of the outer clamp tube 10 and the connector 3. A set of sealing rings 16 are fixedly disposed on the inner side of the sealing sleeve 15. The sealing rings 16 engage with the corresponding side grooves 14. A set of pressure-pressurizing components are detachably disposed on the outside of the sealing sleeve 15. The sealing rings 16 and the sealing sleeve 15 are integrally formed. Through the structure of the pressure-pressurizing components, the sealing sleeve 15 disposed on the outside of the connected outer clamp tube 10 and the connector 3 is pressurized and fixed, thereby improving the sealing performance of the connection between the outer clamp tube 10 and the connector 3.
[0031] Furthermore, such as Figure 5 As shown, the pressurizing assembly includes an inner arc frame 17 that fits against the sealing sleeve 15. Multiple springs 18 are evenly arranged on the outer side of the inner arc frame 17. An outer arc frame 19 is fixedly arranged at the other end of the multiple springs 18. Multiple mounting holes 20 are evenly opened on the side of the outer arc frame 19. The corresponding mounting holes 20 are connected by fasteners, thereby installing the two pressurizing assemblies on the outer side of the sealing sleeve 15. Through the structural arrangement of the pressurizing assembly, the sealing sleeve 15, which is sleeved on the outer side of the connecting tube 10 and the connector 3 after connection, is pressurized and fixed, thereby improving the sealing performance of the connection between the outer tube 10 and the connector 3.
[0032] Working principle: When the pneumatic component body 1 and the air pipe body 2 are sealed together;
[0033] By using the airtight mechanism and the air pipe connection mechanism, the connector 3 and the airtight joint 8 are connected and sealed, thereby improving the sealing performance between the air pipe and the pneumatic component. Specifically, the inner clamp tube 9 is inserted between the inner pipe 4 and the outer pipe 5 and pushed slowly. At this time, the screw-on clamp head 12 on the outer side of the inner clamp tube 9 slides with the screw-on groove 7 on the outer pipe 5, and a set of inner sealing rings 13 on the inner side of the outer clamp tube 10 slides in contact with the outer pipe 5 to seal the outer clamp tube 10 and the outer pipe 5. When the screw-on clamp head 12 cannot be pushed inward, the inner clamp tube 9 is rotated and locked. At this time, the airtight gasket 11 at the end of the inner clamp tube 9 is just locked in the annular groove 6, and the end of the outer clamp tube 10 is in contact with the connector 3.
[0034] By using the structure of the auxiliary sealing mechanism, the sealing sleeve 15 is pre-flipped onto the airtight joint 8. When the end of the outer clamp tube 10 is in contact with the connector 3, the airtight joint 8 is flipped so that the sealing sleeve 15 is fitted onto the outside of the outer clamp tube 10 and the connector 3. The sealing ring 16 and the corresponding side groove 14 on the inner side of the sealing sleeve 15 are pressurized and fixed by the structure of the pressurizing component, thereby improving the sealing performance of the connection between the outer clamp tube 10 and the connector 3. The two inner arc frames 17 are fitted onto the outside of the sealing sleeve 15, and the corresponding mounting holes 20 are connected by fasteners, thereby installing the two pressurizing components on the outside of the sealing sleeve 15. At this time, the spring 18 deforms and generates a restoring force, which pressurizes the inner arc frame 17 onto the sealing sleeve 15, thereby improving the sealing performance of the connection between the outer clamp tube 10 and the connector 3.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
