[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a mechanical-electronic linkage valve controller, including a controller body 1. A protective cover 6 is fastened to the outer shell of the controller body 1. Guide plates 5 are fixedly installed on both sides of the controller body 1. A circular cavity 8 is opened inside the guide plate 5. A strip hole 9 is provided on one side of the circular cavity 8. A ball 13 is slidably arranged inside the circular cavity 8. An extension rod 14 is fixedly installed on one side of the ball 13. A connecting rod 11 is rotatably installed inside the extension rod 14. One end of the connecting rod 11 is fixedly connected to the side plate of the protective cover 6. An annular groove 15 is opened on the inner wall of the extension rod 14. An annular protrusion 12 is fixedly installed on the outer wall of the connecting rod 11. The shape of the annular protrusion 12 is adapted to the shape of the annular groove 15.

[0023] The specific settings and functions of this embodiment are described below. The protective cover 6 is assembled to the outer shell of the controller body 1 by a snap-fit ​​method, which is used to form external protection for the controller body 1. The guide plates 5 fixed on both sides of the controller body 1 have circular cavities 8 inside. The strip hole 9 on one side of the circular cavity 8 provides a path for the movement of the extension rod 14. When it is necessary to open the protective cover 6, the protective cover 6 is pushed directly. When the extension rod 14 moves to the end of the strip hole 9, the protective cover 6 can rotate around the connecting rod 11 as the center, rotating from the top to the bottom of the controller body 1. The protective cover 6 is snapped onto the outer shell of the controller body 1, which can effectively block external dust, moisture, impurities or accidental impacts, and provide reliable protection for the electronic components and mechanical structure inside the controller body 1, extending the overall service life of the controller. The circular cavity 8 of the guide plate 5 provides a stable sliding space for the ball 13. The strip hole 9 limits the movement of the extension rod 14. Together with the ball 13, the frictional resistance of the protective cover 6 during operation is greatly reduced, making the opening and closing of the protective cover 6 easier and smoother, and avoiding jamming.

[0024] Example 2: Figure 1 , Figure 2 and Figure 3As shown, one end of the protective cover 6 is provided with an opening 10, which is located at the wiring port of the controller body 1. A metal block 2 is fixedly installed at the bottom of the controller body 1, and a gasket 7 is fixedly installed at the corner of the lower surface of the controller body 1. A support frame 3 is provided at the bottom of the controller body 1, and a magnetic block 4 is fixedly installed at the top of the support frame 3. The controller body 1 is magnetically attracted to the upper surface of the magnetic block 4 by the metal block 2.

[0025] The overall effect of this embodiment is that the opening 10 corresponds to the wiring port of the controller body 1. When the protective cover 6 is fastened to the top of the controller body 1, the opening 10 provides space for wiring operations and does not affect the normal use of the wiring port. The metal block 2 and the magnetic block 4 cooperate with each other and use magnetic attraction to make the controller body 1 stably adsorbed on the upper surface of the magnetic block 4, realizing the quick connection between the controller body 1 and the support frame 3. At the same time, the pad 7 fixed at the corner of the lower surface of the controller body 1 is located between the controller body 1 and the support frame 3. It can provide cushioning when the controller body 1 is placed on the table after being removed, and this structure will not interfere with the magnetic attraction between the metal block 2 and the magnetic block 4.

[0026] The device's operation and working principle are as follows: The metal block 2 fixed at the bottom of the controller body 1 contacts the magnetic block 4, stabilizing the controller body 1 on the support frame 3 through magnetic attraction, thus connecting the controller body 1 and the support frame 3. The protective cover 6 is fastened to the outer shell of the controller body 1 for protection. To remove the controller body 1, apply upward force to separate the metal block 2 at the bottom of the controller body 1 from the magnetic block 4 at the top of the support frame 3. Then, push the button on the surface of the controller body 1 through the protective cover 6. The connecting rod 11 drives the extension rod 14 on the side of the ball 13, leading to... The circular cavity 8 and the strip hole 9 inside the guide plate 5 determine the movement path of the ball 13 and the extension rod 14. When the extension rod 14 moves to the end of the strip hole 9, the controller body 1 can be placed on the table. At this time, the pad 7 on the lower surface of the controller body 1 contacts the table. At the same time, the protective cover 6 can be rotated with the connecting rod 11 as the center. The protective cover 6 can be rotated from the top to the bottom of the controller body 1. At the same time, the controller body 1 can be lifted by hand for operation. Wiring can be done at the wiring port without disassembling the protective cover 6. The connection can be made using the opening 10.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
