Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an explosion-proof circuit actuator. Background Technology

[0002] A circuit actuator is an electrical device that can disconnect or connect a circuit after receiving an external control signal.

[0003] In the past, circuit actuators did not have a guiding structure when performing circuit connection operations. The connection effect was not precise enough, and electric arcs were easily generated due to friction, which reduced the explosion-proof effect and damaged the actuator. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an explosion-proof circuit actuator with a guiding structure, which makes the connection of the circuit more precise and less prone to arcing due to friction, thus improving the explosion-proof effect and reducing the risk of damage to the actuator.

[0005] The technical solution adopted by this utility model to solve its technical problem is an explosion-proof circuit actuator, including a base, a fixed shell, a second vertical plate, a third rotating shaft, a spiral spring closing rod, and an electrical connection wire. Fixed shells are provided at both ends of the top of the base, and second contact pieces are provided near the top of each fixed shell. A second vertical plate is provided at one end of the top of the base, and a third rotating shaft is provided on one side of the second vertical plate through a rotating groove. A closing rod is connected to the outside of the third rotating shaft, and a spiral spring is provided on the periphery of one end of the third rotating shaft. One end of the spiral spring is connected to the second vertical plate. The bottom end of the closing lever is fitted with a first contact piece by screws. A first vertical plate is provided on the top of the base near the lower end of the closing lever. A first rotating shaft is provided on the inner side of the first vertical plate through a rotating groove. A guide sleeve is connected to the first rotating shaft. An electromagnet is installed in the bottom of the guide sleeve through a fixing groove. A permanent magnet is provided in the guide sleeve near the upper end of the electromagnet. A guide rod is connected to the top of the permanent magnet. A second rotating shaft is connected to one side of the top of the guide rod. A slider is provided on the periphery of the end of the second rotating shaft through a bushing. A sliding groove is opened on one side of the closing lever near the center, and the slider is located in the sliding groove.

[0006] By adopting the above technical solution, after receiving an external control signal, the electromagnet is energized by an externally independent power supply. After being energized, the electromagnet generates electromagnetic force, which attracts the permanent magnet and drives it to move within the guide sleeve. This causes the slider to slide horizontally within the groove. The first contact piece contacts the second contact piece on the top of the fixed shell, thereby connecting the circuit formed by the second contact piece and the reserved hole, thus energizing the circuit.

[0007] Specifically, a reserved hole is provided at one end of the top of the closing rod, and an electrical connection wire is provided in the reserved hole. The electrical connection wire runs from above the closing rod, and its two ends are respectively connected to two sets of the second contact pieces.

[0008] By adopting the above technical solution, when the first contact piece contacts one of the sets of second contact pieces, it is convenient to make the two ends of the electrical connection wire form a connection circuit with the second contact piece.

[0009] Specifically, baffles are provided on both sides of the top of the closing rod, and a limit plate is provided on the top of the closing rod near the upper end of the baffles. The limit plate is fastened to the closing rod by screws.

[0010] By adopting the above technical solution, the limiting plate can be easily fixed to the upper part of the baffle with screws, and the baffle and the limiting plate can be used to limit the electrical connection wire.

[0011] Specifically, each of the fixed shells has a fixed groove on its top, the bottom of the second contact piece is located at the bottom of the fixed groove, one end of the fixed shell is provided with an extension opening near the top, the inner wall of the extension opening is provided with an extension opening near the opening, an intermediate connecting piece is provided in the extension opening, a limiting protrusion is provided on the outer side of one end of the intermediate connecting piece, and the limiting protrusion is located in the stepped groove.

[0012] Specifically, a stud is provided at one end of the inner wall of the extension opening, and an outer contact piece is sleeved on the stud, the outer contact piece being located outside the intermediate connecting piece.

[0013] By adopting the above technical solution, the external electrical connection wire is placed between the outer contact piece and the middle connecting piece by sleeve of the external nut around the end of the stud. By rotating the nut, the external electrical connection wire is pressed by the outer contact piece, thereby connecting the external electrical connection wire to the middle connecting piece.

[0014] Specifically, a cable routing hole is provided through one side of the guide sleeve near the bottom.

[0015] Specifically, the top of the fixed shell is also fixed with a top cover for limiting the top of the second contact piece by screws.

[0016] Specifically, a cable routing hole is provided through one side of the guide sleeve near the bottom, and extension plates are provided on both sides of the base near the ends, with mounting holes provided through one side of the top of each extension plate.

[0017] The beneficial effects of this utility model are: The explosion-proof circuit actuator described in this utility model utilizes an electromagnet energized to generate electromagnetic force, which attracts a permanent magnet, causing the permanent magnet to move within a guide sleeve. This, in turn, causes a slider to slide horizontally within a groove, rotating the closing lever. This causes the first contact piece to contact the second contact piece on the top of the fixed housing, completing the circuit connection action. This actuator has a guiding structure, resulting in more precise circuit connection and reducing the likelihood of arcing due to friction, thus improving the explosion-proof effect and minimizing damage to the actuator.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To ensure the actuator has a guiding structure, the circuit connections are made more precisely to prevent arcing caused by friction due to misalignment, thus improving explosion-proof performance and reducing the risk of damage to the actuator. Figure 1-5As shown, the explosion-proof circuit actuator of this utility model includes a base 1, a fixed shell 21, a second vertical plate 17, a third rotating shaft 18, a spiral spring 19, a closing rod 12, and an electrical connection wire 20. Fixed shells 21 are provided at both ends of the top of the base 1. Second contact pieces 23 are provided near the top of each fixed shell 21. A second vertical plate 17 is provided at one end of the top of the base 1. A third rotating shaft 18 is provided on one side of the second vertical plate 17 via a rotating groove. A closing rod 12 is connected to the outside of the third rotating shaft 18. A spiral spring 19 is provided around one end of the third rotating shaft 18, and one end of the spiral spring 19 is connected to the second vertical plate 17. The bottom end of the closing rod 12 is fitted with a first contact piece 13 by screws. The top of the base 1 is provided with a first vertical plate 4 near the lower end of the closing rod 12. The inner side of the first vertical plate 4 is provided with a first rotating shaft 5 through a rotating groove. A guide sleeve 6 is connected to the first rotating shaft 5. An electromagnet 30 is installed in the bottom of the guide sleeve 6 through a fixing groove. A permanent magnet 31 is provided in the guide sleeve 6 near the upper end of the electromagnet 30. A guide rod 8 is connected to the top of the permanent magnet 31. A second rotating shaft 9 is connected to one side of the top of the guide rod 8. A slider 10 is provided on the outer periphery of the end of the second rotating shaft 9 through a bushing. A sliding groove 11 is opened on one side of the closing rod 12 near the center. The slider 10 is located in the sliding groove 11.

[0023] When in use, after receiving an external control signal, the electromagnet 30 is energized by an externally independent power supply. After being energized, the electromagnet 30 generates electromagnetic force, which attracts the permanent magnet 31 and drives the permanent magnet 31 to move within the guide sleeve 6. This causes the slider 10 to slide horizontally within the slide groove 11. The first contact piece 13 contacts the second contact piece 23 on the top of the fixed shell 21, thereby connecting the circuit formed between the second contact piece 23 and the reserved hole 14, thus connecting the circuit.

[0024] For example, such as Figure 1 and Figure 5 As shown, the present invention also includes a reserved hole 14 through one end of the top of the closing rod 12, an electrical connection wire 20 is provided in the reserved hole 14, the electrical connection wire 20 runs from above the closing rod 12, and the two ends of the electrical connection wire 20 are respectively connected to two sets of the second contact pieces 23.

[0025] When in use, when the first contact piece 13 contacts one of the sets of second contact pieces 23, it facilitates the connection between the two ends of the electrical connection line 20 and the second contact piece 23 to form a circuit.

[0026] For example, such as Figure 1 and Figure 5As shown, the present invention also includes baffles 15 provided on both sides of the top of the closing rod 12, and a limiting plate 16 provided on the top of the closing rod 12 near the upper end of the baffles 15. The limiting plate 16 is fastened to the closing rod 12 by screws.

[0027] In use, the limiting plate 16 can be easily fixed to the upper end of the baffle 15 with screws. The baffle 15 and the limiting plate 16 can be used to limit the electrical connection line 20.

[0028] For example, such as Figure 2 and Figure 3 As shown, the present invention also includes a fixing groove 22 on the top of the fixing shell 21, the bottom end of the second contact piece 23 being located at the bottom of the fixing groove 22, an extension opening 25 being provided at one end of the fixing shell 21 near the top, an extension opening 25 being provided on the inner wall of the extension opening 25 near the opening, an intermediate connecting piece 26 being provided inside the extension opening 25, a limiting protrusion being provided on the outer side of one end of the intermediate connecting piece 26, and the limiting protrusion being located in the stepped groove 27.

[0029] In use, the second contact piece 23 can be easily fixed by the fixing groove 22, and the intermediate connecting piece 26 can be easily fixed by the stepped groove 27.

[0030] For example, such as Figure 3 As shown, the present invention also includes a stud 29 provided at one end of the inner wall of the extension port 25, and an outer contact piece 28 sleeved on the stud 29, the outer contact piece 28 being located outside the intermediate connecting piece 26.

[0031] In use, the external electrical connection wire is placed between the outer contact piece 28 and the intermediate connecting piece 26 by the outer nut being sleeved around the end of the stud 29. By rotating the nut, the external electrical connection wire is pressed by the outer contact piece 28, thereby connecting the external electrical connection wire to the intermediate connecting piece 26.

[0032] For example, such as Figure 1 As shown, the present invention also includes a cable routing hole 7 that is provided through one side of the guide sleeve 6 near the bottom.

[0033] During use, the wiring hole 7 facilitates the routing of the power supply line connected to the electromagnet 30.

[0034] For example, such as Figure 3 As shown, the present invention also includes a top cover 24 for limiting the top end of the second contact piece 23, which is fixed to the top of the fixed shell 21 by screws.

[0035] During use, the top cover 24 facilitates the limiting of the top of the second contact piece 23.

[0036] For example, such as Figure 1 As shown, the present invention also includes a cable routing hole 7 through-hole on one side of the guide sleeve 6 near the bottom, and extension plates 2 on both sides of the base 1 near the ends, with mounting holes 3 through-hole on one side of the top of each extension plate 2.

[0037] In use, the extension plate 2 can be easily fixed to the mounting surface by passing external screws through the mounting hole 3, thus facilitating the installation of this actuator.

[0038] In use, the external electrical connection wire is placed between the outer contact piece 28 and the intermediate connecting piece 26 by the outer nut being sleeved around the end of the stud 29. By rotating the nut, the external electrical connection wire is pressed by the outer contact piece 28, so that the electrical connection wire of the external load is connected to the intermediate connecting piece 26. One end of the intermediate connecting piece 26 is in contact with the second contact piece 23. When the intermediate connecting piece 26 is connected to the electrical connection wire of the external load, it is also electrically connected to the second contact piece 23. After receiving an external control signal, the electromagnet 30 is energized by an externally independent power supply. When energized, the electromagnet 30 generates electromagnetic force, which attracts the permanent magnet 31, causing the permanent magnet 31 to move within the guide sleeve 6. This causes the slider 10 to slide horizontally within the slide groove 11, thereby overcoming the radial force of the spiral spring 19 on the third rotating shaft 18 and causing the closing lever 12 to rotate. This causes the first contact piece 13 to contact the second contact piece 23 on the top of the fixed housing 21, thus connecting the circuit formed by the second contact piece 23 and the reserved hole 14. The actuator has a guiding structure, which makes the connection of the circuit more precise and less prone to arcing due to friction, improving the explosion-proof effect and reducing the risk of damage to the actuator.
