Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic control switch technology, and in particular to a fast-acting magnetic control switch. Background Technology
[0002] Existing fast-acting magnetic switches generally rely on the magnetic field generated by permanent magnets or electromagnetic coils to act on magnetic sensitive elements such as reed switches and Hall elements. When the magnetic field strength reaches the trigger threshold, the magnetic sensitive element directly or indirectly drives the contacts to quickly connect or disconnect the circuit. However, these switches have drawbacks such as easy arc oxidation of the contacts, poor driving accuracy, and lack of active protection.
[0003] In the field of high-speed magnetic control switches, while existing products can achieve rapid circuit switching, they still have many shortcomings: First, arcing is easily generated when the contacts are switched on or off, and contact oxidation is prominent in air environments, resulting in a short service life. Frequent maintenance or replacement not only increases costs but also affects the continuous operating efficiency of the equipment. Second, the drive mechanism mostly uses a single power source (such as a common cylinder or electromagnetic drive), lacking precise mechanical limit and gear adjustment design. Under high-frequency and high-load working scenarios, it is prone to action jamming and positioning deviation, making it difficult to meet the requirements for switch response speed and action stability. Third, there is a lack of active protection mechanism for the contact area, making it impossible to intervene in time before or during the generation of arcs. Relying solely on the arc resistance of the contact material itself is insufficient in safety. Fourth, the coordination between the magnetic attraction structure and mechanical transmission is poor. Either the magnetic attraction stability is poor, resulting in poor contact, or the mechanical transmission has lag, making it slow to switch on and off, making it difficult to simultaneously achieve contact stability and action speed. Summary of the Invention
[0004] The purpose of this invention is to provide a fast-acting magnetic control switch to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a drive assembly, which includes a cylinder and a first mounting shell, wherein the cylinder is disposed inside the first mounting shell; The adjustment assembly includes a movable block, a fixed plate, a first spring, a first magnetic plate, a second magnetic plate, an input wire, a connecting plate, a movable rod, a limiting groove, a fixed column, a third magnetic plate, a second spring, a fourth magnetic plate, an output wire, and a second mounting shell. The movable block is connected to the output end of the cylinder. The fixed plate is located on the lower side of the movable block. The first spring is located on both sides of the fixed plate and its top is fixedly installed on the inner wall of the second mounting shell. The first magnetic plate is located on the lower side of the fixed plate, and the second magnetic plate is located on the upper side of the fixed plate. The input wire is electrically connected to the first and second magnetic plates. The outer wall of the connecting plate is provided with a slide rail and is movably connected to the fixed plate. The limiting groove is located on the outer wall of the movable block. One end of the movable rod is fitted into the limiting groove, and the other end of the movable rod is movably installed on the inner wall of the second mounting shell. The fixed column is fixedly installed on the inner wall of the second mounting shell. The third magnetic plate is laid below the fixed column. The fourth magnetic plate is correspondingly arranged with the first magnetic plate. The second spring is connected between the third magnetic plate and the second mounting shell. The output wire is electrically connected to the fourth magnetic plate. The gas supply assembly includes a gas pump, a gas extraction pipe, a gas delivery pipe, an inert gas cylinder, a diversion channel, and a third mounting housing. The gas pump draws gas through the gas extraction pipe and connects to the inert gas cylinder through the gas delivery pipe. The diversion channel is used to guide the gas to the regulating assembly. The gas pump and the inert gas cylinder are housed inside the third mounting housing. The sensor body is used to detect electric arc sparks and control the operation of the magnetic switch.
[0006] Preferably, the first magnetic plate and the fourth magnetic plate are electromagnetic adsorption structures that generate adsorption force when energized, and the third magnetic plate and the second magnetic plate are electromagnetic adsorption structures.
[0007] Preferably, the movable rod slides and adjusts through a limiting groove, which has an arc-shaped structure.
[0008] Preferably, the flow channel is a channel with an inclined guide surface, so that the gas can flow evenly to the contact area of the regulating component.
[0009] Preferably, there are multiple inert gas cylinders arranged side by side in the third mounting housing and connected in parallel through gas delivery pipes.
[0010] Preferably, the cylinder is a double-acting cylinder, which drives the movable block to reciprocate through the intake and exhaust of gas.
[0011] Preferably, both the first spring and the second spring are compression springs used to provide a restoring force.
[0012] Preferably, one end of the input wire and one end of the output wire are connected to a power source and the device to be controlled, respectively.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when the magnetic switch is activated, the cylinder of the drive component starts, pushing the movable block to drive the fixed plate. The upper and lower magnetic plates on the fixed plate are energized by the input wire to generate attraction. The movable block presses down, causing the first springs on both sides to store energy. The limiting groove on the outer wall of the movable block drives the movable rod to move. The movable rod rotates and slides along the slide rail, so that the first magnetic plate and the fourth magnetic plate engage to complete the electrical connection. The second spring below the fourth magnetic plate buffers the connection, and the output wire supplies power to the device. After the sensor detects an electric arc or signal, it controls the cylinder to retract and drive the movable block to move upward, so that the second magnetic plate and the third magnetic plate engage. The output wire drives the air pump, which draws air and connects to the inert gas cylinder. The mixed gas flows through the drainage groove to the contact area of the adjustment component to prevent electric arc and oxidation. The entire process is continuously protected by gas. The cylinder provides power. The adjustment component, through the cooperation of magnetic attraction, spring and mechanical transmission, ensures stable contact and fast action, so that the switch can operate stably in high-load scenarios, extend its life and improve safety. 2. In this invention, an air pump draws gas through a pipeline and connects it to multiple parallel inert gas cylinders. After mixing, the gas is evenly delivered to the contact area through a guide channel with an inclined guide surface. The inert gas isolates the air from the air to prevent electric arcing and oxidation. A double-acting cylinder drives the movable block to move back and forth. The arc-shaped limiting groove on its outer wall drives the movable rod to precisely adjust the gear (the gear is fixed by the recessed structure in the groove, and the spring enables rapid gear shifting). At the same time, the compressed spring stores energy. When the input wire is energized, the electromagnetic attraction force between the magnetic plates and the spring force combine to push the contacts to quickly close, and the output wire is connected. When the power is off, the spring releases its elastic force to push the component to reset, and the cylinder exhausts gas to drive the movable block to quickly separate the contacts. The entire process is continuously protected by inert gas, the cylinder provides stable power, and the adjustment component, through the cooperation of magnetic attraction, spring, and mechanical transmission, ensures stable contact and rapid switching action, enabling the switch to operate stably under high frequency and high load scenarios, extending its life and improving safety.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] 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.
[0018] Example 1: Refer to Figure 1 - Figure 7As shown: In this embodiment, a fast-acting magnetic switch is included, comprising a drive assembly 1, which includes a cylinder 101 and a first mounting housing 102. The cylinder 101 is disposed within the first mounting housing 102. The adjustment assembly 2 includes a movable block 201, a fixed plate 202, a first spring 203, a first magnetic suction plate 204, a second magnetic suction plate 205, an input wire 206, a connecting plate 207, a movable rod 208, a limiting groove 209, a fixed post 210, a third magnetic suction plate 211, a second spring 212, and a fourth magnetic suction plate 213. Output wire 214 and second mounting shell 215 are connected. Movable block 201 is connected to the output end of cylinder 101. Fixed plate 202 is located on the lower side of movable block 201. First spring 203 is located on both sides of fixed plate 202 and its top is fixedly installed on the inner wall of second mounting shell 215. First magnetic plate 204 is located on the lower side of fixed plate 202, and second magnetic plate 205 is located on the upper side of fixed plate 202. Input wire 206 is electrically connected to first magnetic plate 204 and second magnetic plate 205. The outer wall of connecting plate 207 is provided with slide rail and is connected to fixed plate 205. 202 is a movable connection. A limiting groove 209 is provided on the outer wall of the movable block 201. One end of the movable rod 208 is fitted into the limiting groove 209, and the other end of the movable rod 208 is movably installed on the inner wall of the second mounting shell 215. A fixing post 210 is fixedly installed on the inner wall of the second mounting shell 215. A third magnetic suction plate 211 is laid below the fixing post 210. A fourth magnetic suction plate 213 is correspondingly arranged with the first magnetic suction plate 204. A second spring 212 is connected between the third magnetic suction plate 211 and the second mounting shell 215. An output wire 214 is connected to the fourth magnetic suction plate 204. The magnetic plate 213 is electrically connected. The gas supply assembly 3 includes an air pump 301, an air extraction pipe 302, a gas delivery pipe 303, an inert gas cylinder 304, a diversion groove 305, and a third mounting shell 306. The air pump 301 draws gas through the air extraction pipe 302 and is connected to the inert gas cylinder 304 through the gas delivery pipe 303. The diversion groove 305 is used to guide the gas to the regulating assembly 2. The air pump 301 and the inert gas cylinder 304 are set inside the third mounting shell 306. The sensor body 4 is used to sense electric arc sparks and control the operation of the magnetic switch.
[0019] The effect achieved by the entire embodiment 1 is as follows: When the magnetic switch needs to be activated, the drive assembly 1 then works, the cylinder 101 is activated in the first mounting housing 102, and its output end pushes the movable block 201 to move. The movable block 201 drives the fixed plate 202. The first magnetic suction plate 204 on the lower side and the second magnetic suction plate 205 on the upper side of the fixed plate 202 are energized through the input wire 206 to generate a magnetic attraction force, preparing for subsequent electrical connection. When the movable block 201 continues to press down, the first springs 203 on both sides of the fixed plate 202 are compressed and stored, and then the limiting groove 209 on the outer wall of the movable block 201 drives... One end of the internally fitted movable rod 208 moves, while the other end rotates around the hinge point on the inner wall of the second mounting shell 215 and slides on the slide rail of the connecting plate 207, causing the first magnetic suction plate 204 and the fourth magnetic suction plate 213 to mesh with each other and complete the electrical connection. The second spring 212 below the fourth magnetic suction plate 213 provides cushioning after pressing. The output wire 214 connected to one side of the fourth magnetic suction plate 213 provides continuous output to the device to be controlled. After the sensor body 4 senses an electric arc spark or receives a trigger signal, the cylinder 101 inside the control adjustment component 2 completes the retraction and... The movable block 201 moves upward, causing the second magnetic plate 205 and the third magnetic plate 211 on the upper side of the fixed plate 202 to engage, completing the electrical connection. Through the output wire 214 on one side of the third magnetic plate 211, the air pump 301 inside the gas supply assembly 3 is electrically driven, causing the air pump 301 to draw in external gas through the suction pipe 302, and connect to the inert gas cylinder 304 through the gas delivery pipe 303. After mixing the inert gas, it is guided by the guide groove 305 to the second mounting shell 215 where the regulating assembly 2 is located, filling the contact action area with inert gas to prevent the generation or extinguishing of an electric arc. Throughout the process, the gas supply component 3 continuously provides inert gas to the contact area of the regulating component 2 through the diversion groove 305, isolating the air to prevent contact oxidation and arc damage. The cylinder 101 of the drive component 1 provides initial power. The regulating component 2, through the cooperation of magnetic attraction, spring and mechanical transmission (moving rod 208, limit groove 209, connecting plate 207 slide rail, etc.), uses magnetic attraction to ensure contact stability and spring and mechanical structure linkage to ensure rapid action. This enables the magnetic switch to operate stably in high frequency and high load scenarios, extending its service life and improving safety and reliability.
[0020] Example 2: According to Figure 1 - Figure 4As shown: the first magnetic plate 204 and the fourth magnetic plate 213 are electromagnetic adsorption structures, generating adsorption force when energized; the third magnetic plate 211 and the second magnetic plate 205 are electromagnetic adsorption structures; the movable rod 208 slides and adjusts through the limiting groove 209, which is an arc-shaped structure; the guide groove 305 is a groove with an inclined guide surface, allowing gas to flow evenly to the contact area of the regulating component 2; multiple inert gas cylinders 304 are arranged side by side in the third mounting shell 306 and connected in parallel through the gas supply pipe 303; the cylinder 101 is a double-acting cylinder, driving the movable block 201 to reciprocate through the inlet and outlet of gas; the first spring 203 and the second spring 212 are both compression springs, used to provide reset force; one end of the input wire 206 and the output wire 214 are respectively connected to the power supply and the control device.
[0021] The overall effect of the second embodiment is as follows: the air pump 301 draws in external gas through the air extraction pipe 302, and the gas delivery pipe 303 connects multiple parallel inert gas cylinders 304 in the third mounting shell 306. The mixed inert gas flows into the guide groove 305 with an inclined guide surface. The inclined guide surface makes the gas evenly dispersed and continuously flow to the contact area of the adjustment component 2. The air is isolated in advance with inert gas to avoid the generation of electric arc or oxidation when the contact is activated. The double-acting cylinder 101 of the drive component 1 is started in the first mounting shell 102. The gas intake and exhaust drive the movable block 201 to move back and forth along a preset trajectory. The arc-shaped limiting groove 209 on the outer wall of the movable block 201 then drives one end of the movable rod 208 embedded in the groove to slide and adjust the gear, so that... When the cylinder 101 is not under force, it maintains a stable gear-shifting mode. The recessed structure at the top of the limiting groove 209 locks and limits the movable rod 208. With the help of the first spring 203, the movable rod 208 quickly disengages from the recessed structure of the limiting groove 209, completing another gear-shifting mode. The arc-shaped limiting groove 209 makes the sliding trajectory of the movable rod 208 more precise and without jamming. The other end of the movable rod 208 slides along the slide rail of the connecting plate 207 and rotates around the hinge point of the inner wall of the second mounting shell 215. This pushes the third magnetic suction plate 211 below the fixed column 210 closer to the second magnetic suction plate 205. During this process, the second spring 212 between the third magnetic suction plate 211 and the second mounting shell 215 is compressed and stores elastic force. Simultaneously, the movable block 201 drives the fixed plate 202 to move synchronously. The first springs 203 (compression springs) on both sides of the fixed plate 202 are also compressed and stored energy. After the input wire 206 is connected to the power supply, the first magnetic plate 204 (electromagnetic adsorption structure) and the fourth magnetic plate 213 (electromagnetic adsorption structure), and the third magnetic plate 211 (electromagnetic adsorption structure) and the second magnetic plate 205 (electromagnetic adsorption structure) are respectively energized to generate electromagnetic adsorption forces. The magnetic adsorption force and the elastic force generated by the spring compression form a resultant force, pushing the third magnetic plate 211 to quickly engage with the second magnetic plate 205, and the first magnetic plate 204 to quickly engage with the fourth magnetic plate 213. At this time, the output wire 214 connected to one side of the fourth magnetic plate 213 (the other end is connected to the control device) is connected, realizing... The circuit is quickly connected. When the circuit needs to be disconnected, the input wire 206 is de-energized, and the electromagnetic adsorption structures lose their adsorption force. The first spring 203 and the second spring 212 release their stored elastic force, pushing the fixed plate 202 and the third magnetic suction plate 211 to reset. The double-acting cylinder 101 performs an exhaust action, driving the movable block 201 to move in the opposite direction, thereby causing the movable rod 208 to return to its original position along the arc-shaped limiting groove 209, and the contacts quickly separate. Throughout the entire linkage process, the gas supply component 3 continuously supplies inert gas to the contact area of the regulating component 2 through the drainage groove 305, effectively isolating air to prevent contact oxidation and arc damage. The double-acting cylinder 101 of the driving component 1 provides stable initial power for the switching action and can also achieve precise reciprocating action through gas intake and exhaust.Adjustment component 2 relies on the combination of electromagnetic adsorption, spring energy storage, and mechanical transmission. On the one hand, it utilizes electromagnetic adsorption force to ensure the stability of contact; on the other hand, through the linkage of the spring with the arc-shaped limiting groove 209, the movable rod 208, and other mechanical structures, it ensures the rapid switching action. Ultimately, this allows the magnetic switch to operate stably even under high-frequency, high-load conditions, significantly extending the switch's lifespan and improving the safety and reliability of circuit control.
[0022] Working principle: When the magnetic switch needs to be activated, the drive assembly 1 works first. Its double-acting cylinder 101 is activated within the first mounting housing 102, driving the movable block 201 to move along a preset trajectory through the inlet and outlet of gas. The movable block 201 simultaneously drives the fixed plate 202. At this time, the input wire 206 connected to the power supply is energized, causing the first magnetic suction plate 204 (electromagnetic adsorption structure) on the lower side and the second magnetic suction plate 205 (electromagnetic adsorption structure) on the upper side of the fixed plate 202 to generate a magnetic attraction force, preparing for subsequent electrical connection. As the movable block 201 continues to press down, the first springs 203 (compression springs) on both sides of the fixed plate 202 are compressed and stored. Then, the arc-shaped limiting groove 209 on the outer wall of the movable block 201 drives the movable rod 208 embedded inside. One end moves, and the arc-shaped limiting groove 209 not only makes the sliding trajectory of the movable rod 208 more precise and without jamming, but its top recessed structure can also engage and limit the movable rod 208 when the cylinder 101 does not apply force, maintaining stable gear positioning. Subsequently, the elastic force of the first spring 203 can allow the movable rod 208 to quickly disengage from the recessed structure to complete gear adjustment. The other end of the movable rod 208 rotates around the hinge point of the inner wall of the second mounting shell 215, while sliding on the slide rail of the connecting plate 207, ultimately pushing the first magnetic suction plate 204 and the fourth magnetic suction plate 213 (electromagnetic adsorption structure) to mesh with each other, completing the first electrical connection. The second spring 212 (compression spring) under the fourth magnetic suction plate 213 plays a pressing and buffering role in this process, while the fourth magnetic suction plate The output wire 214 connected to one side of 213 (the other end is connected to the control device) starts to continuously supply power to the controlled device. When the sensor body 4 senses an electric arc or receives a trigger signal, it controls the double-acting cylinder 101 inside the regulating component 2 to complete the recovery action, driving the movable block 201 to move upward, so that the second magnetic suction plate 205 on the upper side of the fixed plate 202 engages with the third magnetic suction plate 211 (electromagnetic adsorption structure), completing another electrical connection. At this time, the output wire 214 on the side of the third magnetic suction plate 211 electrically drives the air pump 301 inside the gas supply component 3. The air pump 301 then draws in external gas through the suction pipe 302, and delivers it through the gas delivery pipe 303 to multiple inert gas cylinders 3 connected in parallel in the third mounting shell 306. In step 04, inert gas is mixed and introduced into a guide channel 305 with an inclined guide surface. The inclined guide surface ensures that the gas is evenly dispersed and continuously flows to the contact area of the regulating component 2. Inert gas is filled in the contact action area to prevent the generation of electric arc or to extinguish any existing electric arc, thus isolating the contact from air in advance to prevent contact oxidation. Throughout the process, the gas supply component 3 continuously supplies inert gas to the contact area of the regulating component 2 through the guide channel 305, effectively solving the problems of contact oxidation and electric arc damage. The double-acting cylinder 101 of the drive component 1 provides stable initial power for the switching action and can also achieve precise reciprocating movement through gas intake and exhaust, ensuring the continuity of action. The regulating component 2 uses electromagnetic attraction force to ensure the contact stability during contact engagement and avoid poor contact.Furthermore, by utilizing the energy storage and reset functions of the first spring 203 and the second spring 212, as well as the mechanical transmission of the movable rod 208, the arc-shaped limiting groove 209, and the connecting plate 207 slide rail, the rapid switching action is ensured, reducing response delay. When the circuit needs to be disconnected, the input wire 206 is de-energized, and each electromagnetic adsorption structure loses its adsorption force. The first spring 203 and the second spring 212 release their stored elastic force, pushing the fixed plate 202 and the third magnetic suction plate 211 to reset. The double-acting cylinder 101 simultaneously performs an exhaust action, driving the movable block 201 to move in the opposite direction, causing the movable rod 208 to return to its original position along the arc-shaped limiting groove 209, and the contacts to separate quickly. This multi-component linkage design allows the magnetic switch to operate stably even under high-frequency and high-load scenarios, significantly extending its service life and greatly improving the safety and reliability of circuit control.
