Description

Technical Field

[0001] This utility model relates to the field of actuator connector technology, and in particular to a leak-proof pneumatic actuator connector. Background Technology

[0002] A pneumatic actuator is a device that uses compressed air as a power source, converting the energy of the compressed air into mechanical energy to drive valves, baffles, and other devices. It is widely used in industrial automation. A pneumatic actuator utilizes the pressure difference created by compressed air inside the actuator to push moving parts such as pistons and vanes, thereby outputting linear or rotary motion. For example, in a piston-type pneumatic actuator, compressed air enters one end of the cylinder, pushing the piston to move within the cylinder; the piston outputs linear motion through the piston rod. In a vane-type pneumatic actuator, compressed air enters the space between the stator and rotor, pushing the vanes to rotate the rotor, outputting rotary motion.

[0003] Existing pneumatic actuator connectors commonly use flange connections. This method utilizes multiple bolt holes on the flange to secure two flanges together, thus connecting the pneumatic actuator to pipelines, equipment, and other components. However, since flange connections require multiple bolts for tightening, each bolt must be accurately passed through its corresponding bolt hole and tightened during installation. This process is not only time-consuming and labor-intensive but also demands a high level of skill from the installers. Even slight deviations in bolt placement or uneven tightening can affect the sealing and stability of the entire connection. Furthermore, disassembling the flange connection is equally cumbersome during equipment maintenance, repair, or when replacing the pneumatic actuator. Multiple bolts must be loosened sequentially, which is even more difficult for large equipment or in situations with limited installation space, significantly extending equipment downtime, increasing maintenance costs, and impacting production efficiency. Therefore, a leak-proof pneumatic actuator connector is needed to solve these problems. Utility Model Content

A rotating sleeve 20 is threadedly fitted inside the groove 19. An annular groove 25 is opened on the surface of the fixed tube 9. A convex annular plate 21 is embedded and rotatably connected inside the annular groove 25. The outer arc wall of the convex annular plate 21 is fixedly connected to the inner wall of the rotating sleeve 20. One end of the L-shaped annular plate 18 is fixedly connected to the mounting tube 23. A pressure gauge 24 is fixedly installed on the top of the mounting tube 23. Through the above arrangement, the embedded annular plate 12 can be embedded inside the groove 10, and the extrusion annular plate 13 will be embedded inside the annular groove 11. At this time, the threaded groove 19 will be embedded inside the rotating sleeve 20 and the rotating sleeve 20 will be rotated, which can achieve the effect of making the L-shaped annular plate 18 move radially along the threaded groove 19.

[0023] like Figure 1 As shown, the bottom of the pneumatic actuator body 1 is fixedly connected to the chassis 2, which is trapezoidal in shape. This configuration can support the bottom of the pneumatic actuator body 1.

A first mounting plate 4 is symmetrically fixed to the surface of the pneumatic actuator body 1 and near the top. A second mounting plate 5 is fixedly connected to both sides of the top cover 3.
