Description

Technical Field

[0001] This utility model relates to the field of measurement switch technology, and in particular to a plug-in rotary measurement switch for low-voltage distribution boxes. Background Technology

[0002] In power systems, low-voltage distribution boxes are key equipment for power distribution and control. Their stable operation is crucial for ensuring the normal operation of various electrical devices. Low-voltage distribution box switches, as the core component of low-voltage distribution boxes, bear important responsibilities such as circuit on / off control and fault protection. In practical applications, low-voltage distribution box switches typically require the following technologies: 1. On / off control technology: Using electromagnetic mechanisms, manual operating mechanisms, etc., to realize the conduction and disconnection of circuits; 2. Multi-electrode switching mechanism: To meet the diverse circuit connection and control requirements of complex power systems, a multi-electrode switching mechanism is set up.

[0003] Existing low-voltage distribution boxes may contain multiple lines. Therefore, in order to perform measurements, multiple switches are needed to control different lines. The integration of multiple switches is low and they occupy a lot of space. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pluggable rotary measuring switch for low-voltage distribution boxes. This solves the technical problem that existing low-voltage distribution boxes may contain multiple lines, requiring multiple switches to control different lines for measurement, resulting in low integration and large space occupation due to the large number of switches.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A plug-in rotary measuring switch for a low-voltage distribution box includes a housing, which includes a base and an end cover. A switching ring is symmetrically and rotatably mounted inside the housing. An electrode holder is fixedly mounted inside the housing. A switching rod is slidably mounted inside the housing. A first spring is installed between the switching rod and the two switching rings. An electrode ring is fixedly mounted on the switching ring. Main electrode plates are symmetrically and fixedly mounted at both ends of the electrode holder. Secondary electrode plates are uniformly and symmetrically fixedly mounted at both ends of the electrode holder. The main electrode plates are in contact with the electrode rings.

[0006] Preferably, the upper and lower pointers are fixedly installed on the side ends of the two switching rings, respectively.

[0007] Preferably, a knob is fixedly installed on the side end of the switching pole.

[0008] Preferably, a first retaining ring is fixedly installed on the side end of the switching ring.

[0009] Preferably, a second spring is symmetrically fixedly installed at both ends of the outer casing.

[0010] Preferably, a second retaining ring is fixedly installed at the end of the second spring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. If the switch lever is pressed down, it will overcome the spring force of the first spring at the base end and slide towards the base end. The inserts at both ends of the switch lever will insert into the channels of the switch ring at the base end. At this time, rotating the switch lever will drive the switch ring at the base end to rotate. The rotation of the switch ring will drive the electrode ring to rotate. The protrusions of the electrode ring can then contact different auxiliary electrode plates during rotation, making the circuit conductive and completing the switching of the first group of control circuits. If the switch lever is pulled up, it will overcome the spring force of the first spring at the end cap end and slide towards the end cap end. The inserts at both ends of the switch lever will insert into the channels of the switch ring at the base end. In the channel of the switching ring at the end cap, rotating the switching rod will cause the switching ring at the end cap to rotate. The rotation of the switching ring will cause the electrode ring to rotate. During the rotation, the protrusion of the electrode ring can contact different auxiliary electrode plates, making the circuit conductive and completing the switching of the second set of control circuits. By pressing or pulling the switching rod, the switching ring at the base end or end cap end can be driven to rotate respectively. The electrode ring rotates with the switching ring, causing its protrusion to contact different auxiliary electrode plates. Thus, a single switch can independently control and switch two circuits, achieving the effect of reducing the footprint and improving space utilization.

[0012] Second, under normal conditions, the switch rod is in the middle position due to the elastic force of the first spring pair at both ends. That is, the switch rod will not contact the switch rings at both ends. Therefore, rotating the switch rod at this time will not drive the switch rings to rotate. In other words, the switch rod can only rotate freely, which can prevent accidental contact during operation.

[0013] Third, during the rotation of the switching ring, the first retaining ring will be rotated synchronously. During the rotation, the first retaining ring can slide by pushing the elastic force of the second spring through the inclined surface of the second retaining ring, ensuring that the switching ring can rotate smoothly. When the switching ring is rotated to the position, the second retaining ring will lock the first retaining ring under the elastic force of the second spring, limiting the position of the knob.

[0017] This application provides a plug-in rotary measuring switch for low-voltage distribution boxes, effectively solving the technical problem that existing low-voltage distribution boxes may contain multiple lines, requiring multiple switches to control different lines for measurement, resulting in low integration and large space occupation. When the switching rod is pressed down, it overcomes the spring force of the first spring at the base end and slides towards the base end. The plugs at both ends of the switching rod will insert into the holes of the switching ring at the base end. Rotating the switching rod at this time will drive the switching ring at the base end... The switching ring rotates, which in turn drives the electrode ring to rotate. During rotation, the protrusions on the electrode ring contact different auxiliary electrode plates, establishing circuit continuity and switching the first set of control circuits. If the switching lever is pulled upwards, it overcomes the spring force of the first spring at the end cap and slides towards the end cap. The inserts at both ends of the switching lever insert into the holes of the switching ring at the end cap. Rotating the switching lever then drives the switching ring at the end cap to rotate, which in turn drives the electrode ring to rotate, allowing the protrusions on the electrode ring to contact different auxiliary electrode plates, thus establishing circuit continuity and switching the first set of control circuits. During rotation, the switch contacts different auxiliary electrode plates, making the circuit conductive and completing the switching of the second set of control circuits. By pressing or pulling the switch lever, the switch ring at the base end or end cover end can be driven to rotate. The electrode ring rotates with the switch ring, causing its protrusion to contact different auxiliary electrode plates, thus enabling one switch to independently control and switch two circuits, achieving the effect of reducing the footprint and improving space utilization. Under normal conditions, the switch lever is in the middle position due to the elastic force of the first spring pair at both ends, meaning the switch lever will not contact the switch rings at both ends. Therefore, rotating the switch lever at this time will not drive the switch ring to rotate, meaning the switch lever can only rotate freely, preventing accidental activation during operation. During the rotation of the switch ring, the first retaining ring will rotate synchronously. During the rotation, the first retaining ring can slide by pushing the elastic force of the second spring through the inclined surface of the second retaining ring, ensuring that the switch ring can rotate smoothly. When the switch ring rotates to the correct position, the second retaining ring will lock the first retaining ring under the elastic force of the second spring, limiting the position of the knob. Example

[0018] like Figure 1-7 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing low-voltage distribution boxes may contain multiple lines, thus requiring multiple switches to control different lines for measurement. This results in low integration of multiple switches and a large space occupation. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides a plug-in rotary measuring switch for low-voltage distribution boxes, including a housing 1, which includes a base and an end cover. A switching ring 2 is symmetrically and rotatably installed inside the housing 1, and an electrode holder 3 is fixedly installed inside the housing 1.

[0019] A switching rod 4 is slidably installed inside the outer casing 1. A first spring 5 is installed between the switching rod 4 and the two switching rings 2. An electrode ring 6 is fixedly installed on the switching ring 2. Main electrode plates 7 are symmetrically fixedly installed at both ends of the electrode holder 3. Secondary electrode plates 8 are uniformly and symmetrically fixedly installed at both ends of the electrode holder 3.

[0020] The main electrode plate 7 is in contact with the electrode ring 6. The upper pointer 9 and the lower pointer 11 are fixedly installed on the side ends of the two switching rings 2 respectively. The knob 12 is fixedly installed on the side end of the switching rod 4. The first retaining ring 13 is fixedly installed on the side end of the switching ring 2. The second spring 14 is symmetrically fixedly installed at both ends of the outer shell 1. The second retaining ring 15 is fixedly installed at the end of the second spring 14.

[0021] Housing 1: Composed of a base and an end cap, it is the external protective structure of the entire switch, providing installation space for internal components. The through hole on the back of the base is used to insert control circuits. The end cap is fixed to the base with bolts to ensure the stability and safety of internal components. Switching ring 2: Its rotation realizes the switching of the circuit. An electrode ring 6 is fixed on the switching ring 2. When rotating, the protruding area of ​​the electrode ring 6 is driven to contact different auxiliary electrode plates 8 to conduct different circuits. The upper pointer 9 and the lower pointer 11 are fixed on the side ends of the two switching rings 2 respectively to indicate the circuit switching status. At the same time, the first retaining ring 13 fixed on the side end of the switching ring 2 cooperates with the second retaining ring 15 at the end of the second spring 14 to realize the limit after the switching ring 2 rotates to the position. Electrode holder 3: The main electrode plate 7 is symmetrically fixed at both ends, and the secondary electrode plate 8 is uniformly and symmetrically fixed at both ends. The main electrode plate 7 contacts the electrode ring 6 to realize the initial circuit connection, and the secondary electrode plate 8 contacts the protrusion of the electrode ring 6 to realize the switching of different lines. It is the key node for circuit connection and switching. Switching rod 4: By pressing or pulling to overcome the elastic force of the first spring 5, the two end rods are inserted into the holes of the switching ring 2 at the base end or end cover end, thereby driving the switching ring 2 to rotate and realize the switching operation of the two sets of control circuits. The knob 12 fixed on the side end of the switching rod 4 makes it convenient for the operator to apply force to press, pull and rotate. First spring 5: Under normal conditions, it keeps the switch rod 4 in the middle position to prevent accidental contact. When the switch rod 4 is pressed or pulled, its elastic force must be overcome so that the switch rod 4 is connected to the switch ring 2 at the corresponding end to realize the line switching function. Electrode ring 6: Its protruding part contacts different auxiliary electrode plates 8 during the rotation of the switching ring 2, realizing the conduction and switching of the circuit, and is the direct action component for realizing line switching; Main electrode plate 7: The protruding design allows it to maintain contact with electrode ring 6, achieving initial circuit connection and providing a basis for subsequent circuit switching; Sub-electrode 8: It contacts the protrusion of electrode ring 6 to realize the conduction of different circuits and works with electrode ring 6 to complete the circuit switching function. Upper pointer 9: When the end cap switching ring 2 rotates, it drives the upper pointer 9 to rotate synchronously. The operator can intuitively see the protrusion of the end cap electrode ring 6 aligned with the auxiliary electrode plate 8, thereby understanding the switching status of the line. Lower pointer 11: When the switching ring 2 at the base end rotates, it synchronously drives the lower pointer 11 to rotate, so that the operator can intuitively see the protrusion of the electrode ring 6 at the base end aligned with the auxiliary electrode plate 8 and know the status of the circuit. Knob 12: Fixed to the side of the switch rod 4, allowing operators to press, pull, and rotate the switch rod 4 to drive the switch ring 2 and thus complete the line switching. First retaining ring 13: During the rotation of the switching ring 2, it interacts with the inclined surface of the second retaining ring 15 to push the second spring 14 to slide, ensuring that the switching ring 2 rotates smoothly. When the switching ring 2 rotates to the position, it cooperates with the second retaining ring 15 and limits the position of the knob 12 under the elastic force of the second spring 14. Second spring 14: During the rotation of the switching ring 2, the interaction between the second retaining ring 15 and the first retaining ring 13 provides elastic support to ensure the smooth rotation of the switching ring 2, and assists the second retaining ring 15 in limiting the position of the knob 12 after the switching ring 2 has rotated to the correct position. Second retaining ring 15: Cooperates with first retaining ring 13. When the switching ring 2 rotates, the interaction of the inclined plane pushes the second spring 14 to generate sliding force, ensuring that the switching ring 2 rotates smoothly. After the switching ring 2 rotates to the position, it locks the first retaining ring 13 under the action of the second spring 14, thereby limiting the position of the knob 12.

[0022] Working principle: The first step is to separate the base and end cap of the housing 1 during installation. Then, insert the two sets of control lines along the through holes on the back of the base of the housing 1. Then, connect the control lines to the main electrode plate 7 and the auxiliary electrode plate 8 at both ends of the electrode base 3 respectively. For example, the power supply line or control line is connected to the main electrode plate 7, and the other auxiliary electrode plates 8 are connected to the control element or different gears of the control unit. Then, connect the end cap to the base and fix it with bolts. At this time, since the main electrode plate 7 protrudes, it can maintain contact with the electrode ring 6, so that the electrode ring 6 and the main electrode plate 7 are connected.

[0023] The second step involves the following steps: Under normal conditions, the switching rod 4 is in the middle position due to the elastic force of the first springs 5 ​​at both ends. This means the switching rod 4 will not contact the switching rings 2 at either end. Therefore, rotating the switching rod 4 at this time will not cause the switching rings 2 to rotate; the switching rod 4 can only rotate freely, preventing accidental activation during operation. If the switching rod 4 is pressed down, it will overcome the elastic force of the first springs 5 ​​at the base end and slide towards the base end. The inserts at both ends of the switching rod 4 will then insert into the holes of the switching rings 2 at the base end. Rotating the switching rod 4 at this time will cause the switching rings 2 at the base end to rotate, and the rotation of the switching rings 2 will then rotate the electrode rings 6. When rotated, the protrusions of electrode ring 6 can contact different auxiliary electrode plates 8 during rotation, making the circuit conductive and completing the switching of the first set of control circuits. If the switching rod 4 is pulled upward, the switching rod 4 will overcome the elastic force of the first spring 5 at the end cover end and slide towards the end cover end. The inserts at both ends of the switching rod 4 will be inserted into the holes of the switching ring 2 at the end cover end. At this time, rotating the switching rod 4 will drive the switching ring 2 at the end cover end to rotate. The rotation of the switching ring 2 will drive the electrode ring 6 to rotate. The protrusions of electrode ring 6 can contact different auxiliary electrode plates 8 during rotation, making the circuit conductive and completing the switching of the second set of control circuits.

[0024] Thirdly, during the circuit switching process, if the switching ring 2 at the end cap rotates, it will simultaneously drive the upper pointer 9 to rotate, so that it can be clearly seen which of the sub-electrode pieces 8 the protrusion of the electrode ring 6 at the end cap is aligned with. If the switching ring 2 at the base rotates, it will simultaneously drive the lower pointer 11 to rotate, so that it can be clearly seen which of the sub-electrode pieces 8 the protrusion of the electrode ring 6 at the base is aligned with, thus showing the status of the circuit. During the rotation of the switching ring 2, it will simultaneously drive the first retaining ring 13 to rotate. During the rotation, the first retaining ring 13 can slide by pushing the elastic force of the second spring 14 through the inclined surface of the second retaining ring 15, ensuring that the switching ring 2 can rotate smoothly. When the switching ring 2 rotates to the position, the second retaining ring 15 will lock the first retaining ring 13 under the elastic force of the second spring 14, limiting the position of the knob 12.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
