[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The present application provides an actuator connection bracket that can be switched manually or automatically, which is mainly used to solve the problem that the existing valves generally realize automatic control of the valves by installing electric or pneumatic actuators. Once the actuator fails, the on-site maintenance personnel need to stop the equipment to repair or replace the actuator, which will cause the company to stop production for a certain period of time and bring losses to the company. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0024] A manually and automatically switchable actuator connection bracket mainly comprises a top plate 1, an actuator body 8 and a support rod 3 are fixed on both sides of the top plate 1, an upper cover 4 is connected to the axis of the actuator body 8, an upper groove 41 is configured on the outer side wall of one end of the upper cover 4, an end of the support rod 3 is connected to a bottom plate 2, a valve body 9 is connected to the bottom plate 2, a lower cover 5 is connected to the axis of the valve body 9, a lower groove 51 is configured on the outer side wall of the lower cover 5 near one end of the upper cover 4, a spring 6 is embedded in the lower groove 51, a handle 7 is hinged in the lower groove 51, and the handle 7 is movably clamped in the upper groove 41 through the spring 6, wherein the specific connection method is as follows:

[0025] The top plate 1 and the actuator body 8 are fixed by bolts 11 to ensure their stability and firmness. This connection method is simple and reliable, and can effectively prevent movement or loosening between the two; the upper cover 4 is fixed to the axis of the actuator body 8 by pins 42. This fixing method is simple and effective, and can prevent the upper cover 4 from sliding or rotating during operation; the bottom plate 2 and the valve body 9 are fixed by bolts 21. This connection method can ensure the alignment between the bottom plate 2 and the valve body 9 and provide sufficient support and stability; the lower cover 5 is fixed to the axis of the valve body 9 by pins 52. This fixing method can prevent the lower cover 5 from sliding or rotating during operation, and at the same time ensure the sealing performance of the valve body 9; this actuator connection bracket that can be switched manually or automatically has the advantages of simple structure, convenient operation, long service life, balanced stability, etc., and can improve the efficiency and reliability of the fluid control system.

[0026] In this example, see Figure 4 There are three support rods 3 and they are evenly distributed. Three through holes 22 are penetrated on the bottom plate 2. The three through holes 22 correspond to the three support rods 3 one by one. The ends of the support rods 3 are fixed with screws 31 that movably penetrate the corresponding through holes 22. A nut 32 is threadedly sleeved on the screws 31. This arrangement can increase the stability and balance of the entire connecting bracket and reduce instability or deviation caused by external forces.

[0027] A connecting shaft 53 penetrating the lower groove 51 is inserted on the lower cover 5, and one end of the handle 7 is movably sleeved on the connecting shaft 53, so that the connection of the handle 7 is more stable; the spring 6 is installed in the lower groove 51 and presses the handle 7 upward so that the handle 7 is embedded in the upper groove 41. This design can prevent the handle 7 from accidentally sliding or swinging, thereby ensuring the accuracy and safety of the operation.

[0028] The device uses bolts, pins and other fixings to connect the various components, ensuring that the structure of the connecting bracket is firm and reliable, avoiding malfunction or damage due to loosening or movement. The clamping design of the handle 7 and the design of the spring 6 allow the connecting bracket to be switched manually or automatically, and different operating modes can be selected according to needs, providing more flexibility and convenience. A reasonable fixing and connecting method is adopted to ensure the stability and durability of the connecting bracket, extend its service life, reduce the number of repairs and replacements, and reduce maintenance costs. The evenly distributed support rods 3 and appropriate fixing methods ensure that the overall balance and stability of the connecting bracket are ensured to prevent displacement or instability due to external forces.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
