Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic valve solenoid head structure, specifically to an electromagnetic valve solenoid head structure. Background Technology

[0002] A solenoid valve is an automated control element that uses electromagnetic principles to control the flow of fluids (such as gases, liquids, or steam). It uses an electric current to activate an electromagnetic coil, which in turn drives the valve core to open or close the valve, regulating the flow of fluid. Solenoid valves are widely used in automated control systems, industrial equipment, and household appliances.

[0003] Traditional solenoid valves typically have a simple solenoid head design with limited protection. After prolonged operation, the solenoid coil is easily contaminated by dust, oil, and other pollutants, affecting its normal operation and potentially causing equipment failure. Furthermore, the maintenance methods for existing solenoid heads are cumbersome, usually requiring the disassembly of multiple fixed components, which is not only time-consuming and labor-intensive but may also damage other components of the equipment.

[0004] Therefore, it is necessary to design a solenoid valve solenoid head structure to solve the above problems. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, 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 than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a solenoid valve solenoid head structure, including a solenoid valve body 1. A fixing block 18 is installed on the top of one side of the solenoid valve body 1, and a valve head protective cover 2 is movably connected to the top of the fixing block 18. Insertion hooks 14 are fixedly connected to both sides of the bottom end of the valve head protective cover 2. Two symmetrical sliding grooves 9 are formed on the top of the fixing block 18, and insertion grooves 15 are formed inside each of the two sliding grooves 9. Sliding insert plates 12 are slidably inserted into the interior of each of the two sliding grooves 9, and insertion interfaces 13 are formed on the outer surface of each of the two sliding insert plates 12. A connecting piece 8 is fixedly connected to one side of each of the two sliding insert plates 12, and the two insertion hooks 14 are respectively slidably inserted into the interior of the two insertion interfaces 13. Two symmetrical second springs 11 are fixedly connected to one side of the inner cavity of the sliding groove 9, and square sockets are opened on the outer surfaces of the two sliding insert plates 12. Insertion plates 7 are slidably inserted into the interior of each of the two square sockets. A connector 3 is fixedly connected to the top of both insertion plates 7. Insertion pieces 19 are fixedly connected to one side of each of the two insertion plates 7. Sliding slots 17 are opened on both sides of the outer surface of the valve head protective cover 2. One end of each of the two insertion plates 7 and the two insertion pieces 19 are slidably engaged inside the two sliding slots 17. A fixing frame 6 is fixedly connected to the top of the valve head protective cover 2, and two symmetrical first springs 4 are fixedly connected to the top of the connector 3.

The fixed frame 6 has square openings on both sides, and the top of the insertion plate 7 is slidably disposed inside the two square openings. Utilizing the elastic connection of the two sliding plates 12 within the two sliding grooves 9, the two insertion hooks 14 are slidably inserted into the two insertion ports 13, thereby achieving a movable connection between the valve head protective cover 2 and the fixed block 18. When the two insertion hooks 14 are inserted into the two insertion ports 13, they will push the two insertion ports 13 to move. When the protruding parts at the bottom of the two insertion hooks 14 are inserted into the bottom of the two sliding plates 12 and the two insertion grooves 15, the two sliding plates 12 are respectively in the two... The elastic rebound of the second spring 11 causes the two plug-in hooks 14 to fix the two sliding plates 12, thereby preventing the valve head protective cover 2 from falling off. At the same time, the insertion of the two plug-in plates 7 and the two square sockets ensures the sliding limitation of the two sliding plates 12. When it is necessary to inspect and clean the coil inside the valve head protective cover 2, the pull tab 5 can be pulled to disengage the two plug-in plates 7 from the two square sockets, so that the two sliding plates 12 can be pressed by the connecting piece 8, and the two plug-in hooks 14 can be removed from the two plug-in interfaces 13. Thus, when the coil inside the valve head protective cover 2 has been working for a long time, if dust enters or inspection is required, it is convenient to clean and inspect the coil, thereby improving the service life of the overall device.

[0022] To facilitate limiting the sliding of the two sliding plates 12, the two plug plates 7 are slidably inserted into the interior of the two square sockets, and the two sides of the two plug plates 7 are respectively attached to the two sides of the two square sockets.

[0023] To facilitate the sliding adjustment of the positions of the two plug-in plates 7, the connector 3 is U-shaped, and the two ends of the U-shape of the connector 3 are respectively fixed to the top of the two plug-in plates 7, and the two ends of the connector 3 are respectively slidably disposed inside the two square openings.

[0024] Furthermore, in order to facilitate the elastic adjustment of the positions of the two connectors 3, the two ends of the two first springs 4 are respectively fixed between the top of the connector 3 and the top of the inner cavity of the fixing frame 6, and the two first springs 4 are respectively located on both sides of the plug post 20.

[0025] Furthermore, in order to facilitate the sliding engagement between the two plug-in hook blocks 14 and the two sliding insert plates 12, the width of the two plug-in interfaces 13 is greater than the bottom width of the plug-in hook blocks 14, and an arc-shaped surface is provided on one side of each of the two plug-in interfaces 13.

However, the present invention is not limited to the specific details of the above embodiments.
