Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, and in particular to a solenoid valve with a wireless beam integrated plug. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility.

[0003] For example, the Chinese utility model solenoid valve with publication number CN222416283U has a snap-fit ​​part located on a second mounting plate and a connecting part located on a valve seat component. The magnetic guide frame and the valve seat component are connected by the snap-fit ​​part and the connecting part engaging with each other. This design is simple in structure and facilitates the connection and assembly of the valve seat component and the magnetic guide frame. In traditional technical solutions, the magnetic guide frame and the valve seat component are connected by fasteners, which is cumbersome and inefficient. Compared with traditional technical solutions, this design offers greater ease of operation and higher assembly efficiency, but such a structure still has the following significant drawbacks:

[0004] Existing solenoid valves are usually equipped with a plug. The metal tongue on the plug is exposed when not connected. Once subjected to external force, it is easy to bend, which will affect the service life of the plug. Summary of the Invention

[0005] This utility model aims to solve one of the technical problems existing in the prior art.

[0006] This application provides a solenoid valve with a wireless beam integrated plug, including a solenoid valve body and a coil assembly; a pair of metal tongues are fixed on the solenoid valve body, and a retractable protective component is provided inside the solenoid valve body, which is used to protect the pair of metal tongues when retracted.

[0007] Furthermore, the protective assembly includes a protective shell, an adjusting component, and an adjusting disc. The solenoid valve body is provided with a sliding groove, in which a rotating shaft is rotatably installed. An adjusting disc is fixed on the rotating shaft. Four No. 1 magnets are evenly spaced and distributed circumferentially on the adjusting disc, and adjacent No. 1 magnets have opposite magnetic properties. The protective shell is slidably installed in the sliding groove. Two No. 2 magnets with the same magnetic properties are evenly spaced and distributed circumferentially on the end of the protective shell facing the adjusting disc. The adjusting component drives the adjusting disc to rotate, so that a pair of No. 1 magnets are aligned with a pair of No. 2 magnets.

[0008] Furthermore, the adjusting component includes a connecting shaft, a knob, and a transmission component. The solenoid valve body is provided with a rotating groove, in which the connecting shaft is rotatably installed. One end of the connecting shaft extends out of the solenoid valve body and is fixedly connected to the knob, while the other end is connected to the adjusting disc via the transmission component.

[0009] Furthermore, the transmission components include a first bevel gear and a second bevel gear. The first bevel gear is fixed on the rotating shaft, and the end of the connecting shaft away from the knob extends into the sliding groove and is fixedly connected to the second bevel gear, which meshes with the first bevel gear.

[0010] Furthermore, a limiting disc is fixed on the knob, and a limiting arc groove is provided on the limiting disc. A limiting cylinder that slides with the limiting arc groove is fixed on the solenoid valve body.

[0011] Furthermore, the outer perimeter of the knob is provided with anti-slip texture.

[0012] Furthermore, a limiting block is fixed on the protective shell, and a limiting groove is provided on the sliding groove to slide in cooperation with the limiting block.

[0013] Furthermore, the solenoid valve body is equipped with a cover for isolating the magnetic field, and the cover is wrapped around the outside of the protective component.

[0014] The beneficial effects of this utility model are as follows:

[0015] With the protective shell, when the metal tongue is not needed, the protective shell can extend partially out of the solenoid valve body to prevent the metal tongue from bending under external force, effectively protecting the metal tongue. By adjusting the setting of the disc, magnet one, magnet two and the adjusting component, the protective shell can be quickly retracted / extended by the attraction / repulsion between magnet one and magnet two, making operation convenient.

[0025] The electromagnetic valve of the wireless beam integrated plug provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown, this application embodiment provides a solenoid valve with a wireless beam integrated plug, including a solenoid valve body 1 and a coil assembly 2; a pair of metal tongues 3 are fixed on the solenoid valve body 1, and a protective component that can be extended / retracted is provided inside the solenoid valve body 1. The protective component is used to protect the pair of metal tongues 3 when extended.

[0028] In this embodiment of the application, due to the above-described structure, the solenoid valve body 1 is provided with a coil assembly 2 and an iron core. A pair of metal tongues are respectively connected to the two ends of the coil assembly 2. By inserting the pair of metal tongues into the external socket, the coil assembly 2 can be energized, thereby causing the iron core to generate a magnetic field, driving the push rod to slide upward and stretching the spring located between the iron core and the push rod. After the energization is stopped, the iron core is pushed to reset under the action of the spring.

[0029] Example 2:

[0030] like Figures 2 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the protective component includes a protective shell 15, an adjusting member 17, and an adjusting disc 13. The solenoid valve body 1 is provided with a sliding groove 11, and a rotating shaft 12 is rotatably installed in the sliding groove 11. An adjusting disc 13 is fixedly installed on the rotating shaft 12. Four first magnets 14 are evenly spaced circumferentially distributed on the adjusting disc 13, and adjacent first magnets 14 have opposite magnetic properties. The protective shell 15 is slidably installed in the sliding groove 11. Two second magnets 16 with the same magnetic properties are evenly spaced circumferentially distributed on the end of the protective shell 15 facing the adjusting disc 13. The adjusting member 17 drives the adjusting disc 13 to rotate, so that a pair of first magnets 14 are aligned with a pair of second magnets 16.

[0031] Furthermore, the adjusting component 17 includes a connecting shaft 171, a knob 172, and a transmission component 173. The solenoid valve body 1 is provided with a rotating groove 174, and the connecting shaft 171 is rotatably installed in the rotating groove 174. One end of the connecting shaft 171 extends out of the solenoid valve body 1 and is fixedly connected to the knob 172, while the other end is connected to the adjusting disc 13 through the transmission component 173.

[0032] Furthermore, the transmission component 173 includes a first bevel gear 175 and a second bevel gear 176. The first bevel gear 175 is fixed on the rotating shaft 12. The end of the connecting shaft 171 away from the knob 172 extends into the sliding groove 11 and is fixedly connected to the second bevel gear 176 that meshes with the first bevel gear 175.

[0033] Furthermore, a limiting disc 181 is fixed on the knob 172, and a limiting arc groove 182 is provided on the limiting disc 181. A limiting cylinder 183 that slides with the limiting arc groove 182 is fixed on the solenoid valve body 1.

[0034] Furthermore, the outer periphery of the knob 172 is provided with anti-slip texture 177.

[0035] Furthermore, a limiting block 191 is fixed on the protective shell 15, and a limiting groove 192 is provided on the sliding groove 11 to slide in cooperation with the limiting block 191.

[0036] Furthermore, the solenoid valve body 1 is provided with a cover 4 for isolating the magnetic field, and the cover 4 is wrapped around the outside of the protective component.

[0037] In this embodiment of the application, due to the above-described structure, when not in use, by rotating the knob 172 counterclockwise by 90 degrees, the knob 172 drives the connecting shaft 171 and the second bevel gear 176 to rotate synchronously. Since the first bevel gear 175 and the second bevel gear 176 mesh, the first bevel gear 175, the adjusting disk 13 and the rotating shaft 12 are driven to rotate 90 degrees, so that the pair of first magnets 14 on the adjusting disk 13 with the same magnetism as the second magnet 16 are aligned with the pair of second magnets 16. At this time, under the action of magnetic force, the protective shell 15 will be pushed out of the solenoid valve body 1, and the pair of metal tongues 3 will be stored in the silicone block 151 with the storage groove.

[0038] When needed, by rotating knob 172 90 degrees clockwise, knob 172 drives connecting shaft 171 and second bevel gear 176 to rotate synchronously. Since first bevel gear 175 and second bevel gear 176 mesh, first bevel gear 175, adjusting disk 13 and rotating shaft 12 are driven to rotate 90 degrees, so that a pair of first magnets 14 on adjusting disk 13 with opposite magnetism to second magnet 16 are aligned with a pair of second magnets 16. At this time, under the action of magnetic force, the protective shell 15 will slide in the direction of adjusting disk 13 until it is completely retracted into the solenoid valve body 1. At this time, a pair of metal tongues 3 can be used normally.

[0039] A limiting disc 181 is fixed on the knob 172, and a limiting arc groove 182 is provided on the limiting disc 181. A limiting cylinder 183 is fixed on the solenoid valve body 1 and slides with the limiting arc groove 182. The limiting arc groove 182 limits the rotation range of the knob 172 to 90 degrees. When the limiting cylinder 183 is in contact with one end of the limiting arc groove 182, a pair of first magnets 14 with the same magnetic properties as the second magnet 16 are aligned with a pair of second magnets 16. When the limiting cylinder 183 is in contact with the other end of the limiting arc groove 182, a pair of first magnets 14 with opposite magnetic properties as the second magnet 16 are aligned with a pair of second magnets 16.

[0040] The outer periphery of the knob 172 is provided with anti-slip texture 177, so that it will not easily slip during the rotation even if the hands are sweaty, oily or slightly dirty.

[0041] A limiting block 191 is fixed on the protective shell 15, and a limiting groove 192 is provided on the sliding groove 11 to slide with the limiting block 191. The limiting groove 192 and the limiting block 191 can prevent the protective shell 15 from accidentally separating from the solenoid valve body 1 during the extension process.

[0042] The solenoid valve body 1 is equipped with a cover 4 for isolating the magnetic field. The cover 4 is wrapped around the outside of the protective component, which can prevent the first magnet 14 and the second magnet 16 from affecting the normal operation of the solenoid valve.

[0043] The casing 4 is made of nickel silver, permalloy or silicon steel.
