Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to an operating mechanism, a rotary switch and a power distribution system. Background Art

[0002] A rotary switch is a switch device that changes the on / off state of a circuit by rotating it, and is widely used in various electronic devices and circuits. Specifically, the rotary switch includes a knob, a drive mechanism, and a contact system. The drive mechanism includes an operating shaft, an energy storage module, and a rotating shaft. The knob and the energy storage module are both matched with the operating shaft. The rotating shaft is matched with the contact system. The contact system includes a moving contact and a stationary contact that cooperate with each other.

[0003] The operator rotates the knob to drive the operating shaft to rotate, and the energy storage module stores energy when the operating shaft rotates. When the rotary switch needs to be automatically opened, the drive mechanism is driven to release the elastic potential energy of the energy storage module. Under the action of this elastic potential energy, the shaft rotates, driving the moving contact to rotate until it is separated from the static contact, so as to realize the automatic opening of the rotary switch.

[0004] However, when the operating shaft of the rotary switch in the prior art is deformed or aged so that the rotation of the operating shaft is blocked, the rotary switch may not be able to automatically open reliably, thereby reducing the safety of the rotary switch. Utility Model Content

[0005] The present application provides an operating mechanism, a rotary switch and a power distribution system, so that when the operating shaft is deformed or aged so that the rotation of the operating shaft is blocked, the rotary switch can still be reliably and automatically opened, thereby improving the safety of the rotary switch.

[0006] In the first aspect, the present application provides an operating mechanism for use in a rotary switch, the operating mechanism comprising a first elastic member, a second elastic member, an operating shaft and a rotating shaft module. The first elastic member, the second elastic member and the operating shaft are all mounted on the rotating shaft module. The first end of the first elastic member is fixedly connected to the rotating shaft module, and the second end of the first elastic member can rotate under the drive of the operating shaft so that the first elastic member stores energy. The second elastic member abuts the operating shaft and the rotating shaft module. When the rotation of the operating shaft is blocked during the automatic opening process of the rotary switch, the first elastic member releases elastic potential energy, and the second elastic member can absorb the elastic potential energy released by the first elastic member. Among them, the elastic potential energy released by the first elastic member is greater than the elastic potential energy absorbed by the second elastic member, so that the first elastic member can drive the rotating shaft module from the closing position to the opening position.

[0007] Through the above scheme, the elastic potential energy released by the first elastic member is still surplus after being absorbed by the second elastic member. Since the elastic potential energy of the second elastic member is zero when the rotating shaft module is in the closing position, when the elastic potential energy released by the first elastic member is still surplus after being absorbed by the second elastic member, even if the second elastic member absorbs the elastic potential energy released by the first elastic member, the elastic potential energy of the second elastic member will not be greater than the elastic potential energy of the first elastic member. Therefore, even if the second elastic member absorbs the elastic potential energy released by the first elastic member due to the obstruction of the rotation of the operating shaft, the surplus elastic potential energy of the first elastic member can also drive the rotating shaft module to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0008] In a possible design, when the shaft module rotates from the closing position to the opening position, the force value of the first elastic member changes from large to small, the force value of the second elastic member changes from small to large, and the minimum force value of the first elastic member is greater than the maximum force value of the second elastic member.

[0009] Through the above scheme, when the rotating shaft module is rotated to the opening position, the force value of the first elastic member is still greater than the force value of the second elastic member. Since the first elastic member and the second elastic member are two interacting structural members, the force value of the first elastic member is opposite to the force value of the second elastic member. Based on this, when the force value of the first elastic member is greater than the force value of the second elastic member, the combined force direction of the force value of the first elastic member and the force value of the second elastic member will be the same as the force value direction of the first elastic member. In this way, when the rotating shaft module is rotated to the opening position, the rotating shaft module still has a tendency to rotate in the direction of opening the rotary switch, thereby improving the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0010] In a possible design, the minimum force value of the first elastic member is greater than the sum of the maximum force value of the second elastic member and the resistance of the first elastic member in the process of releasing elastic potential energy.

[0011] Through the above scheme, even if there are various resistances that consume the elastic potential energy released by the first elastic member during the process of the shaft module rotating from the closing position to the opening position, the force value of the first elastic member can still be greater than the sum of the force value of the second elastic member and the resistance when the shaft module rotates to the opening position. Since the direction of the force applied to the shaft module by the second elastic member and the resistance is opposite to the direction of the force applied to the shaft module by the first elastic member, when the minimum force value of the first elastic member is greater than the sum of the maximum force value of the second elastic member and the resistance in the process of releasing the elastic potential energy of the first elastic member, the combined force direction of the force applied to the shaft module by the first elastic member, the force applied to the shaft module by the second elastic member, and the force applied to the shaft module by the resistance will be the same as the direction of the force applied to the shaft module by the first elastic member. In this way, when the shaft module rotates to the opening position, the shaft module still has a tendency to rotate in the direction of opening the rotary switch, thereby improving the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0012] In a possible design, when the shaft module rotates from the closing position to the intermediate position, the force value of the first elastic member is greater than the force value of the second elastic member. When the shaft module rotates from the intermediate position to the opening position, the force value of the first elastic member is less than the force value of the second elastic member. The intermediate position is between the closing position and the opening position, and the intermediate position is closer to the opening position than the closing position.

[0013] During the process of the shaft module rotating from the closing position to the middle position, the force value of the first elastic member is greater than the force value of the second elastic member, so that the shaft module can perform an acceleration movement with reduced acceleration, which is convenient for the shaft module to accelerate from the closing position to the middle position. During the process of the shaft module rotating from the middle position to the opening position, the force value of the first elastic member is less than the force value of the second elastic member, so that the shaft module can perform a deceleration movement with increased acceleration. Since the middle position is between the closing position and the opening position, and the middle position is closer to the opening position relative to the closing position, when the shaft module rotates from the middle position to the opening position, the shaft module only needs to rotate a small angle to rotate to the opening position when the shaft module performs a deceleration movement, which improves the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0014] In a possible design, the angle through which the shaft module rotates from the closing position to the opening position is a first angle, and the angle through which the shaft module rotates from the middle position to the opening position is a second angle, and the second angle accounts for 20% to 25% of the first angle.

[0015] Through the above solution, the shaft module rotates from the closing position to the middle position, and the shaft module rotates three-quarters to four-fifths of the total stroke of the entire opening process, so that the remaining stroke only accounts for one-fifth to one-quarter of the total stroke. In this way, in the process of the shaft module rotating from the middle position to the opening position, the shaft module only needs to rotate a small angle to rotate to the opening position, which improves the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0016] In a possible design, the operating shaft includes a first driving portion and a second driving portion, and the rotating shaft module includes a first abutting portion and a second abutting portion. When the rotating shaft module is in the closing position, the first end of the second elastic member abuts against the first driving portion, and the second end of the second elastic member abuts against the first abutting portion. When the rotating shaft module is in the opening position, the first end of the second elastic member abuts against the second abutting portion, and the second end of the second elastic member abuts against the second driving portion.

[0017] Through the above scheme, during the process of the rotating shaft module rotating from the closing position to the opening position, the first abutting portion pushes the second end of the second elastic member, so that the second end of the second elastic member rotates with the rotation of the rotating shaft module. In order to maintain a steady state, the first end of the second elastic member will push the first driving portion, so that the operating shaft rotates with the rotation of the first end of the second elastic member until the rotating shaft module rotates to the opening position. Assuming that the rotation of the operating shaft is blocked during the automatic opening process, as analyzed above, the operating shaft will become the source of resistance for the end of the second elastic member to rotate with the rotating shaft module, so that the second elastic member absorbs the elastic potential energy released by the first elastic member. However, the present application sets the elastic potential energy released by the first elastic member to be greater than the elastic potential energy absorbed by the second elastic member, so that the elastic potential energy released by the first elastic member is still surplus after being absorbed by the second elastic member. Through this surplus elastic potential energy, the rotating shaft module can also be driven to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0018] In a possible design, the operating mechanism also includes a lock, which is connected to the shaft module. The lock includes a first locking portion and an unlocking portion, the first elastic member includes a second locking portion, the first locking portion is located on the rotation path of the second locking portion, and the first locking portion can lock the second locking portion so that the first elastic member stores energy. The shaft module includes a second locking portion, and when the shaft module is in the closed position, the rotation of the second locking portion is restricted, so that the shaft module remains in the closed position. When the rotary switch is disengaged and the lock is forced to act, the first locking portion can release the lock on the second locking portion, and the unlocking portion can press the second locking portion to release the restriction of the second locking portion, so that the shaft module can be rotated from the closed position to the open position.

[0019] Through the above scheme, when the rotary switch needs to be tripped, the present application can realize double unlocking through the action of the lock. In this way, the first elastic member can release energy freely, and the shaft module can be rotated from the closing position to the opening position only under the drive of the first elastic member, without being affected by whether the operating shaft rotates or the size of the rotation resistance of the operating shaft. Therefore, even if the operating shaft is deformed or aged, or the rotation resistance of the operating shaft increases, the torque of the operating shaft cannot be effectively transmitted to the shaft module, and the rotary switch can be reliably and automatically opened, reducing the possibility of safety problems and improving the safety of the use of the rotary switch. In addition, the function of the lock is enriched, so that the lock can be reused without the need to set up other structural parts to release the restriction of the shell on the second locking part, saving the number of structural parts used, thereby simplifying the structure of the operating mechanism.

[0020] In a second aspect, the present application provides a rotary switch, which includes a contact system, a tripping system and the operating mechanism of the first aspect, the contact system is connected to the shaft module of the operating mechanism, the tripping system and the operating mechanism cooperate with each other, and the rotary switch can be automatically opened when the tripping system is actuated.

[0021] In the present application, the automatic opening of the rotary switch can be achieved by the elastic potential energy released by the first elastic member to drive the rotation of the shaft module, and even if the rotation of the operating shaft is obstructed so that the second elastic member absorbs the elastic potential energy released by the first elastic member, the excess elastic potential energy of the first elastic member can also drive the shaft module to rotate from the closed position to the open position, thereby improving the reliability of the automatic opening of the rotary switch and thus improving the safety of the use of the rotary switch.

[0022] In a third aspect, the present application provides a power distribution system, which includes a current detection device, a controller, and a rotary switch of the second aspect, wherein the current detection device, the controller, and the rotary switch are electrically connected in sequence. The current detection device is used to send a fault signal to the controller when a preset fault is detected in the power distribution system. The controller is used to receive the fault signal and generate a trip signal when the fault signal is received. The controller is also used to send a trip signal to the rotary switch so that the rotary switch is automatically tripped.

[0023] Through the above scheme, when the current detection device detects that there is a preset fault in the power distribution system, it can send a fault signal to the controller. Correspondingly, the controller can receive the fault signal sent by the current detection device, and generate a trip signal when receiving the fault signal, and send the trip signal to the trip system of the rotary switch. The trip system of the rotary switch is activated when receiving the trip signal, so that the rotary switch is automatically opened. In the present application, the automatic opening of the rotary switch can be achieved by the elastic potential energy released by the first elastic member to drive the rotation of the shaft module, and even if the second elastic member absorbs the elastic potential energy released by the first elastic member due to the obstruction of the rotation of the operating shaft, the surplus elastic potential energy of the first elastic member can also drive the shaft module to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch, thereby improving the safety of the use of the rotary switch.

[0024] In a possible design, the preset faults include one or more of string reverse connection, current backflow, and bus short circuit.

[0025] The beneficial effects provided in the possible designs of the second aspect and the third aspect can be referred to the beneficial effects brought about by the possible implementation modes of the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present application provides an operating mechanism 100 , which is applied to a rotary switch 1 . Figure 1 This is a structural schematic diagram of a rotary switch provided by an embodiment of the present application with the knob and part of the upper cover hidden. Figure 2 A partial structural diagram of an operating mechanism provided in an embodiment of the present application, Figure 3 for Figure 2 The schematic diagram of the structure after the energy storage shaft is hidden. Figure 4 A cross-sectional view of a part of the structure of an operating mechanism provided in an embodiment of the present application, such as Figures 1 to 4 As shown, the operating mechanism 100 includes a first elastic member 110 , a second elastic member 120 , an operating shaft 130 and a rotating shaft module 140 .

[0055] The first elastic member 110, the second elastic member 120 and the operating shaft 130 are all installed on the rotating shaft module 140. The first end of the first elastic member 110 is fixedly connected to the rotating shaft module 140, and the second end of the first elastic member 110 can rotate under the drive of the operating shaft 130, so that the first elastic member 110 stores energy. The second elastic member 120 abuts against the operating shaft 130 and the rotating shaft module 140. When the rotary switch 1 is tripped and the rotation of the operating shaft 130 is blocked, the first elastic member 110 releases elastic potential energy, and the second elastic member 120 can absorb the elastic potential energy released by the first elastic member 110. Among them, the elastic potential energy released by the first elastic member 110 is greater than the elastic potential energy absorbed by the second elastic member 120, so that the first elastic member 110 can drive the rotating shaft module 140 to rotate from the closing position to the opening position.

[0056] The shaft module 140 rotates around a fixed axis during the closing and opening processes of the rotary switch 1. When the shaft module 140 is in the closing position, the rotary switch 1 is in the closing state. When the shaft module 140 is in the opening position, the rotary switch 1 is in the opening state. The closing position of the shaft module 140 may refer to the position of a preset part on the shaft module 140 when the rotary switch 1 is in the closing state. Similarly, the opening position of the shaft module 140 may refer to the position of a preset part on the shaft module 140 when the rotary switch 1 is in the opening state. Exemplarily, the preset part may be the second locking portion 1422 to be described later.

[0057] like Figure 1 As shown, the operating mechanism 100 includes a housing 150, and the housing 150 may include an upper cover 151 and a base 152. The upper cover 151 and the base 152 may be connected by bolt connection or clamping connection. A cavity is formed between the upper cover 151 and the base 152 connected to each other, and the shaft module 140 is located in the cavity.

[0058] like Figure 2 As shown, the shaft module 140 includes an energy storage shaft 141 and a shaft 142 that cover each other. The energy storage shaft 141 and the shaft 142 can be connected by bolt connection, clamping or plugging. An installation space is formed between the interconnected energy storage shaft 141 and the shaft 142, the first elastic member 110 and the second elastic member 120 are located in the installation space, and the operating shaft 130 is at least partially located in the installation space. The interconnected energy storage shaft 141 and the shaft 142 can rotate together.

[0059] When the first elastic member 110 is installed between the energy storage shaft 141 and the shaft 142 , the first elastic member 110 is closer to the energy storage shaft 141 , so the first end of the first elastic member 110 can be fixedly connected to the energy storage shaft 141 of the shaft module 140 . Figure 5 A schematic diagram of the structure of an energy storage shaft provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the energy storage shaft 141 can be provided with a limiting groove 1411, combined with Figure 3 and Figure 5 The first end of the first elastic member 110 extends into the limiting groove 1411 and contacts the groove wall of the limiting groove 1411 so as to be limited by the groove wall of the limiting groove 1411, so that the end of the first elastic member 110 can always be fixed in the limiting groove 1411 during the energy storage process and the energy release process.

[0060] The first elastic member 110 may be a torsion spring or a spring sheet, etc. In addition, the limiting groove 1411 may be a circular groove or a square groove, etc., provided on the side of the energy storage shaft 141 facing the shaft 142, or may be a groove structure formed by the gap between two protrusions provided on the side of the energy storage shaft 141 facing the shaft 142. As long as the limiting groove 1411 can limit the position of the first end of the first elastic member 110, the embodiment of the present application does not limit this.

[0061] Figure 6 A schematic diagram of the structure of an operating shaft provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the operating shaft 130 may include a main shaft 131 and a lever 132 that are connected to each other. The lever 132 is roughly disc-shaped. The lever 132 is located in an installation space formed between the energy storage shaft 141 and the shaft 142. One end of the main shaft 131 away from the lever 132 is located outside the installation space, and the end of the main shaft 131 located in the installation space is connected to the lever 132.

[0062] When the operating shaft 130 has the above structure, the second end of the first elastic member 110 may be located on the rotation path of the lever 132 , so that when the operating shaft 130 rotates, the second end of the first elastic member 110 is driven to rotate through the lever 132 .

[0063] After the second end of the first elastic member 110 is rotated to a certain extent driven by the lever 132 or other structural members, it can be locked by the lock 160. Since the first end of the first elastic member 110 is fixedly connected to the shaft module 140, when the shaft module 140 is fixed, the operating shaft 130 drives the second end of the first elastic member 110 to rotate, and when the second end of the first elastic member 110 is locked with the lock 160, the energy accumulated by the first elastic member 110 is stored, so that the first elastic member 110 is in an energy storage state. The structure of the lock 160 will be described in detail later, and will not be described here for the time being.

[0064] Similar to the first elastic member 110, the second elastic member 120 may also be a torsion spring or a spring sheet. When the second elastic member 120 is installed between the energy storage shaft 141 and the shaft 142, the second elastic member 120 is relatively close to the shaft 142 and the lever 132, so one end of the two ends of the second elastic member 120 can abut against the shaft 142, and the other end of the two ends can abut against the lever 132. Among them, the end of the second elastic member 120 can abut against the shaft 142 and the lever 132 when the rotary switch 1 is in the two stable states of the opening state and / or the closing state. The second elastic member 120 can also abut against the shaft 142 and the lever 132 during the movement of the shaft 142 and the lever 132, which is not limited in the embodiment of the present application. The abutment relationship between the two ends of the second elastic member 120 and the shaft 142 and the lever 132 will be described in detail later, and will not be expanded here. The second elastic member 120 is a necessary structural member for manual opening and manual closing of the rotary switch 1.

[0065] When the rotary switch 1 needs to be automatically opened, the lock between the second end of the first elastic member 110 and the lock buckle 160 is released, and the first elastic member 110 releases the elastic potential energy. The second end of the first elastic member 110 is restricted by the shell 150 when the first elastic member 110 starts to release the elastic potential energy. In order to maintain a steady state, the first end of the first elastic member 110 drives the rotating shaft module 140 to rotate in the direction of opening the rotary switch 1 under the action of the elastic potential energy released by the first elastic member 110, thereby realizing automatic opening of the rotary switch 1.

[0066] Assuming that the rotation of the operating shaft 130 is not hindered during the automatic opening of the rotary switch 1, and the operating shaft 130 can rotate normally and smoothly in the direction of opening the rotary switch 1, when the first elastic member 110 releases elastic potential energy and drives the rotating shaft module 140 to rotate in the direction of opening the rotary switch 1, the operating shaft 130 will not hinder the rotation of the end of the second elastic member 120, so that both ends of the second elastic member 120 will rotate with the rotation of the rotating shaft module 140. In this case, the second elastic member 120 will not become a resistance in the rotation process of the rotating shaft module 140, and the second elastic member 120 will not absorb the elastic potential energy released by the first elastic member 110.

[0067] However, in actual use, there is a possibility that the rotation of the operating shaft 130 is blocked during the automatic opening process of the rotary switch 1. The rotation of the operating shaft 130 is blocked, which may mean that the operating shaft 130 is deformed, aged or tilted, or the external force applied to the operating shaft 130 when the rotary switch 1 is closed is not removed in time, so that the operating shaft 130 cannot rotate normally and smoothly during the automatic opening process of the rotary switch 1.

[0068] Since one end of the second elastic member 120 is in contact with the lever 132, when the rotation of the operating shaft 130 is blocked and cannot rotate with the end of the second elastic member 120, the operating shaft 130 will become the source of resistance to the end of the second elastic member 120 rotating with the shaft module 140. Based on this, when the other end of the second elastic member 120 is in contact with the shaft 142, the second elastic member 120 will become the source of resistance to the rotation of the shaft module 140. In this case, the second elastic member 120 will absorb or consume the elastic potential energy released by the first elastic member 110. This will cause the problem that the rotary switch 1 cannot be reliably opened automatically.

[0069] In view of this, in the embodiment of the present application, the elastic potential energy released by the first elastic member 110 is set to be greater than the elastic potential energy absorbed by the second elastic member 120, so that the first elastic member 110 can drive the rotating shaft module 140 to rotate from the closing position to the opening position.

[0070] In the embodiment of the present application, since the second elastic member 120 abuts against the operating shaft 130 and the rotating shaft module 140, during the automatic opening process of the rotary switch 1, assuming that the rotation of the operating shaft 130 is blocked, the operating shaft 130 will hinder the end of the second elastic member 120 from rotating with the rotating shaft module 140, so that the second elastic member 120 may absorb the elastic potential energy released by the first elastic member 110. The second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110, which means that the elastic potential energy released by the first elastic member 110 is consumed by the second elastic member 120, reducing the elastic potential energy of the first elastic member 110 used to drive the rotating shaft module 140 to rotate to the opening position.

[0071] In the present application, the elastic potential energy released by the first elastic member 110 is set to be greater than the elastic potential energy absorbed by the second elastic member 120, so that the elastic potential energy released by the first elastic member 110 is still surplus after being absorbed by the second elastic member 120. Since the elastic potential energy of the second elastic member 120 is zero when the rotating shaft module 140 is in the closing position, when the elastic potential energy released by the first elastic member 110 is still surplus after being absorbed by the second elastic member 120, even if the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110, the elastic potential energy of the second elastic member 120 will not be greater than the elastic potential energy of the first elastic member 110. Therefore, even if the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110 due to the obstruction of the rotation of the operating shaft 130, the rotating shaft module 140 can be driven to rotate from the closing position to the opening position through the surplus elastic potential energy of the first elastic member 110, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the use safety of the rotary switch 1.

[0072] Figure 7A schematic diagram of a relationship between the force values ​​of a first elastic member and a second elastic member during the opening process provided in an embodiment of the present application, wherein the vertical axis can represent the force value, and the horizontal axis can represent the position of the shaft module 140 during the opening process of the rotary switch 1. In some embodiments, as Figure 7 As shown, during the process of the rotating shaft module 140 rotating from the closing position to the opening position, the force value of the first elastic member 110 changes from large to small, the force value of the second elastic member 120 changes from small to large, and the minimum force value of the first elastic member 110 can be greater than the maximum force value of the second elastic member 120.

[0073] After the lock between the second end of the first elastic member 110 and the lock catch 160 is released, the first elastic member 110 enters the stage of releasing elastic potential energy. Therefore, during the process of the rotating shaft module 140 rotating from the closing position to the opening position, the force value of the first elastic member 110 changes from large to small. In this way, the force value of the first elastic member 110 is the largest when the rotating shaft module 140 is in the closing position, and the force value of the first elastic member 110 is the smallest when the rotating shaft module 140 is in the opening position.

[0074] Based on the above description, when the rotation of the operating shaft 130 is blocked, the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110. Therefore, during the process of releasing the elastic potential energy of the first elastic member 110, the force value of the second elastic member 120 changes from small to large. In this way, the force value of the second elastic member 120 is the smallest when the rotating shaft module 140 is in the closing position, and the force value of the second elastic member 120 is the largest when the rotating shaft module 140 is in the opening position.

[0075] Based on the above analysis, the minimum force value of the first elastic member 110 is greater than the maximum force value of the second elastic member 120, which means that when the rotating shaft module 140 is in the open position, the force value of the first elastic member 110 is still greater than the force value of the second elastic member 120. Figure 7 It can be seen that during the entire process of the rotating shaft module 140 rotating from the closing position to the opening position, the force value of the first elastic member 110 is always greater than the force value of the second elastic member 120. This means that during the entire process of the rotating shaft module 140 rotating from the closing position to the opening position, the elastic potential energy released by the first elastic member 110 is always greater than the elastic potential energy absorbed by the second elastic member 120.

[0076] In this embodiment, the minimum force value of the first elastic member 110 is set to be greater than the maximum force value of the second elastic member 120, so that when the rotating shaft module 140 rotates to the opening position, the force value of the first elastic member 110 is still greater than the force value of the second elastic member 120. Since the first elastic member 110 and the second elastic member 120 are two interacting structural members, the force value of the first elastic member 110 is opposite to the force value of the second elastic member 120. Based on this, when the force value of the first elastic member 110 is greater than the force value of the second elastic member 120, the combined force direction of the force value of the first elastic member 110 and the force value of the second elastic member 120 will be the same as the force value direction of the first elastic member 110. In this way, when the rotating shaft module 140 rotates to the opening position, the rotating shaft module 140 still has a tendency to rotate in the direction of opening the rotary switch 1, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the use safety of the rotary switch 1.

[0077] Furthermore, considering that in the process of releasing the elastic potential energy of the first elastic member 110, not only the second elastic member 120 consumes the elastic potential energy released by the first elastic member 110 due to the obstruction of the operating shaft 130, but also the elastic potential energy released by the first elastic member 110 is consumed due to the obstruction of the rotation of other structural members. Based on this, in some embodiments, the minimum force value of the first elastic member 110 may be greater than the sum of the maximum force value of the second elastic member 120 and the resistance in the process of releasing the elastic potential energy of the first elastic member 110.

[0078] Exemplarily, the other structural member in the front section may be the shaft module 140. Accordingly, the resistance in the front section may include, but is not limited to, the friction force generated between the shaft module 140 and the housing 150 when the shaft module 140 rotates relative to the housing 150 under the action of the elastic potential energy released by the first elastic member 110, and the air resistance encountered by the shaft module 140 when the shaft module 140 rotates under the action of the elastic potential energy released by the first elastic member 110. It is understandable that in the process of releasing the elastic potential energy of the first elastic member 110, there may be other resistances, which may be included in the scope defined by the technical solution of the present application.

[0079] This embodiment not only takes into account the situation in the previous embodiment where the second elastic member 120 consumes the elastic potential energy released by the first elastic member 110 only because the operating shaft 130 encounters resistance, but also takes into account the situation where the elastic potential energy released by the first elastic member 110 is also consumed when the hinge module 140 encounters resistance when rotating relative to the shell 150. The minimum force value of the first elastic member 110 is set to be greater than the sum of the maximum force value of the second elastic member 120 and the resistance in the process of the first elastic member 110 releasing the elastic potential energy.

[0080] Based on this, even if there are various resistances that consume the elastic potential energy released by the first elastic member 110 during the process of the rotating shaft module 140 rotating from the closing position to the opening position, the force value of the first elastic member 110 can still be greater than the sum of the force value of the second elastic member 120 and the resistance when the rotating shaft module 140 rotates to the opening position. Since the directions of the forces applied to the rotating shaft module 140 by the second elastic member 120 and the resistance are opposite to the direction of the force applied to the rotating shaft module 140 by the first elastic member 110, when the minimum force value of the first elastic member 110 is greater than the sum of the maximum force value of the second elastic member 120 and the resistance during the process of the first elastic member 110 releasing the elastic potential energy, the combined force direction of the force applied to the rotating shaft module 140 by the first elastic member 110, the force applied to the rotating shaft module 140 by the second elastic member 120, and the force applied to the rotating shaft module 140 by the resistance will be the same as the direction of the force applied to the rotating shaft module 140 by the first elastic member 110. Thus, when the rotating shaft module 140 rotates to the opening position, the rotating shaft module 140 still has a tendency to rotate in the direction of opening the rotary switch 1 , thereby improving the reliability of the automatic opening of the rotary switch 1 and thus improving the use safety of the rotary switch 1 .

[0081] Figure 8 A schematic diagram of another embodiment of the present application showing the relationship between the force values ​​of the first elastic member and the second elastic member during the opening process, wherein the vertical axis can represent the force value, and the horizontal axis can represent the position of the shaft module 140 during the opening process of the rotary switch 1. In other embodiments, such as Figure 8 As shown, when the rotating shaft module 140 rotates from the closing position to the middle position (the middle position is the position corresponding to the intersection of the two straight lines on the horizontal axis in the figure), the force value of the first elastic member 110 is greater than the force value of the second elastic member 120. When the rotating shaft module 140 rotates from the middle position to the opening position, the force value of the first elastic member 110 is less than the force value of the second elastic member 120.

[0082] The middle position is located between the closing position and the opening position, and the middle position is closer to the opening position than the closing position.

[0083] Since the force value is a vector, the force value of the first elastic member 110 being greater than the force value of the second elastic member 120 may mean that the magnitude of the force value of the first elastic member 110 is greater than the magnitude of the force value of the second elastic member 120. Similarly, the force value of the first elastic member 110 being less than the force value of the second elastic member 120 may mean that the magnitude of the force value of the second elastic member 120 is less than the magnitude of the force value of the second elastic member 120. The subsequent description of the magnitude relationship of two force values ​​refers to the relationship between the magnitudes of the two force values, or the magnitude relationship between the absolute values ​​of the two force values.

[0084] like Figure 8As shown, in the process of rotating the shaft module 140 from the closing position to the middle position, the force value of the first elastic member 110 changes from large to small, the force value of the second elastic member 120 changes from small to large, and the force value of the first elastic member 110 is greater than the force value of the second elastic member 120. When the rotating shaft module 140 rotates to the middle position, the force value of the first elastic member 110 is equal to the force value of the second elastic member 120. That is, the force value of the first elastic member 110 and the force value of the second elastic member 120 reach a balance when the rotating shaft module 140 rotates to the middle position, and the middle position corresponds to the force balance point of the first elastic member 110 and the second elastic member 120. In the process of rotating the shaft module 140 from the middle position to the opening position, the force value of the first elastic member 110 changes from large to small, the force value of the second elastic member 120 changes from small to large, and the force value of the first elastic member 110 is less than the force value of the second elastic member 120.

[0085] Fig. 9 A schematic diagram of the acceleration change of a shaft module during the opening process provided in an embodiment of the present application, Fig. 9 The vertical axis can represent the magnitude of acceleration, and the horizontal axis can represent the position of the shaft module 140 during the opening process of the rotary switch 1. Fig.10 A schematic diagram of the speed change of a rotating shaft module during the opening process provided by an embodiment of the present application, Fig.10 The vertical axis can represent the speed, and the horizontal axis can represent the position of the shaft module 140 during the opening process of the rotary switch 1.

[0086] like Fig. 9 and Fig.10 As shown, during the process of the shaft module 140 rotating from the closing position to the middle position, the acceleration and speed of the shaft module 140 are both positive, and the acceleration of the shaft module 140 changes from large to small, and the speed of the shaft module 140 changes from small to large. Figures 8 to 10 It can be seen that in this process, the rotating shaft module 140 performs an accelerating motion with a decreasing acceleration.

[0087] When the rotating shaft module 140 rotates from the middle position to the opening position, the acceleration of the rotating shaft module 140 is negative, and the acceleration of the rotating shaft module 140 changes from small to large in the reverse direction. The speed of the rotating shaft module 140 is positive, and the speed of the rotating shaft module 140 changes from large to small. Figures 8 to 10 It can be seen that in this process, the rotating shaft module 140 performs a deceleration motion with increasing acceleration.

[0088] In this embodiment, during the process of the rotating shaft module 140 rotating from the closing position to the intermediate position, the force value of the first elastic member 110 is greater than the force value of the second elastic member 120, so that the rotating shaft module 140 can perform an acceleration movement with reduced acceleration, which is convenient for the rotating shaft module 140 to accelerate from the closing position to the intermediate position. During the process of the rotating shaft module 140 rotating from the intermediate position to the opening position, the force value of the first elastic member 110 is less than the force value of the second elastic member 120, so that the rotating shaft module 140 can perform a deceleration movement with increased acceleration. Since the intermediate position is located between the closing position and the opening position, and the intermediate position is closer to the opening position relative to the closing position, when the rotating shaft module 140 rotates from the intermediate position to the opening position, the rotating shaft module 140 only needs to rotate a small angle to rotate to the opening position when the rotating shaft module 140 performs a deceleration movement, which improves the reliability of the automatic opening of the rotary switch 1, thereby improving the use safety of the rotary switch 1.

[0089] Further, in some embodiments, assuming that the angle through which the shaft module 140 rotates from the closed position to the open position is a first angle, and the angle through which the shaft module 140 rotates from the middle position to the open position is a second angle, then the second angle can account for 20% to 25% of the first angle.

[0090] For example, assuming that the value of the first angle is 180 degrees, the value of the second angle can be 36 degrees to 45 degrees. In practice, the value of the first angle can also be 176 degrees or 185 degrees, etc. The embodiment of the present application does not specifically limit the values ​​of the first angle and the second angle, as long as the second angle accounts for 20% to 25% of the first angle.

[0091] In addition, the percentage of the second angle to the first angle can be greater than or equal to 20% and less than or equal to 25%. Of course, the percentage can also be slightly less than 20% or slightly greater than 25%, as long as the shaft module 140 can be smoothly rotated from the middle position to the open position.

[0092] Through the above solution, the rotating shaft module 140 rotates from the closing position to the middle position, and the rotating shaft module 140 rotates three-quarters to four-fifths of the total stroke of the entire opening process, so that the remaining stroke only accounts for one-fifth to one-quarter of the total stroke. In this way, in the process of the rotating shaft module 140 rotating from the middle position to the opening position, the rotating shaft module 140 only needs to rotate a small angle to rotate to the opening position, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the use safety of the rotary switch 1.

[0093] Fig.11 A schematic diagram of the structure of a rotating shaft provided in an embodiment of the present application is shown below in conjunction with Figures 1 to 6 ,as well as Fig.11The abutting relationship between the two ends of the second elastic member 120 and the rotating shaft 142 and the lever 132 is described in detail.

[0094] like Figures 1 to 6 ,as well as Fig.11 As shown, the operating shaft 130 includes a first driving portion 13211 and a second driving portion 13212, and the rotating shaft module 140 includes a first abutting portion 14211 and a second abutting portion 14212. When the rotating shaft module 140 is in the closing position, the first end of the second elastic member 120 abuts against the first driving portion 13211, and the second end of the second elastic member 120 abuts against the first abutting portion 14211. When the rotating shaft module 140 is in the opening position, the first end of the second elastic member 120 abuts against the second abutting portion 14212, and the second end of the second elastic member 120 abuts against the second driving portion 13212.

[0095] The lever 132 may be provided with an extension arm 1321 toward the rotation shaft 142. The number of the extension arm 1321 may be one or two. When the number of the extension arm 1321 is one, the extension arm 1321 includes two side walls that are opposite to each other, such as Figure 6 As shown, the first driving portion 13211 may be a side wall of the two side walls close to the first end of the second elastic member 120, and the second driving portion 13212 may be a side wall of the two side walls close to the second end of the second elastic member 120. When there are two extension arms 1321, the first driving portion 13211 may be a side wall of the first extension arm 1321 facing away from the second extension arm 1321, and the second driving portion 13212 may be a side wall of the second extension arm 1321 facing away from the first extension arm 1321.

[0096] like Fig.11 As shown, the rotating shaft 142 is provided with a boss 1421, and the boss 1421 includes two walls in opposite positions. The first abutment portion 14211 can be the wall of the two walls close to the second end of the second elastic member 120, and the second abutment portion 14212 can be the wall of the two walls close to the first end of the second elastic member 120.

[0097] The extension arm 1321 and the boss 1421 are both located between two ends of the second elastic member 120 .

[0098] Through the above-mentioned abutment relationship between the two ends of the second elastic member 120 and the rotating shaft 142 and the lever 132, when the rotary switch 1 is automatically opened and the rotating shaft module 140 is rotated from the closing position to the opening position, the first abutment portion 14211 pushes the second end of the second elastic member 120, so that the second end of the second elastic member 120 rotates with the rotation of the rotating shaft module 140. In order to maintain a steady state, the first end of the second elastic member 120 will push the first driving portion 13211, so that the operating shaft 130 rotates with the rotation of the first end of the second elastic member 120 until the rotating shaft module 140 rotates to the opening position. Assuming that the rotation of the operating shaft 130 is blocked during the automatic opening process, as analyzed above, the operating shaft 130 will become the source of resistance to the end of the second elastic member 120 rotating with the rotating shaft module 140, so that the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110. In the present application, the elastic potential energy released by the first elastic member 110 is set to be greater than the elastic potential energy absorbed by the second elastic member 120, so that the elastic potential energy released by the first elastic member 110 is still surplus after being absorbed by the second elastic member 120. The surplus elastic potential energy can also drive the rotating shaft module 140 to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the safety of the use of the rotary switch 1.

[0099] Fig.12 A schematic diagram of the structure of a lock provided in an embodiment of the present application, Fig.13 A schematic diagram of a structure of a lock buckle and a first elastic member in a locked state provided by an embodiment of the present application, Fig.14 A schematic diagram of a structure of a lock buckle and a first elastic member unlocking process provided in an embodiment of the present application is shown below in conjunction with Figures 1 to 6 ,as well as Figure 12 to Figure 14 The structure of the lock 160 and the matching relationship between the lock 160 and the hinge module 140 are described in detail.

[0100] like Figures 1 to 6 ,as well as Figure 12 to Figure 14 As shown, the lock 160 is connected to the shaft module 140. The lock 160 includes a first locking portion 161 and an unlocking portion 162. The first elastic member includes a second locking portion. The first locking portion 161 is located on the rotation path of the second locking portion. The first locking portion 161 can lock the second locking portion so that the first elastic member 110 stores energy. The shaft module 140 includes a second locking portion 1422. When the shaft module 140 is in the closed position, the rotation of the second locking portion 1422 is restricted, so that the shaft module 140 is maintained in the closed position. When the rotary switch 1 is tripped and the lock 160 is forced to move, the first locking portion 161 can release the lock on the second locking portion, and the unlocking portion 162 can press the second locking portion 1422 to release the restriction of the second locking portion 1422, so that the shaft module 140 can be rotated from the closed position to the open position.

[0101] The lock buckle 160 is at least partially located in the installation space formed between the energy storage shaft 141 and the shaft 142. When the lock buckle 160 is connected to the shaft module 140, it can be connected to the energy storage shaft 141 in a rotational and / or translational manner, and can also be connected to the shaft 142 in a rotational and / or translational manner.

[0102] Take the lock 160 being rotatably connected to the rotating shaft 142 as an example. Figure 3 and Fig.12 As shown, the rotating shaft 142 can be provided with a rotating shaft 1423, and the locking buckle 160 can be provided with a mounting hole 163. The mounting hole 163 of the locking buckle 160 is sleeved on the rotating shaft 1423, and the locking buckle 160 can rotate around the rotating shaft 1423, so that the rotational connection between the locking buckle 160 and the rotating shaft 142 can be realized.

[0103] Taking the example of the lock 160 being connected to the rotating shaft 142 in a translational manner, a slide groove can be provided on the side of the rotating shaft 142 facing the energy storage rotating shaft 141, and a slider can be provided on the side of the lock 160 facing the rotating shaft 142. The slider is located in the slide groove and can translate in the slide groove, so that the lock 160 and the rotating shaft 142 can be connected in a translational manner.

[0104] In practice, the lock buckle 160 can be connected to the housing 150 in addition to the hinge module 140. When the lock buckle 160 is connected to the housing 150, the lock buckle 160 can be connected to the upper cover 151 in rotation and / or in translation, or can be connected to the base 152 in rotation and / or in translation. The implementation method of connecting the lock buckle 160 to the housing 150 can refer to the implementation method of connecting the lock buckle 160 to the hinge module 140, and will not be described in detail here.

[0105] like Figure 4 and Fig.11 As shown, the second locking portion 1422 may be disposed on the side of the rotating shaft 142 facing the energy storage rotating shaft 141. Alternatively, the second locking portion 1422 may also be disposed on the side of the energy storage rotating shaft 141 facing the rotating shaft 142. Figure 4 and Fig.11 As shown, the second locking portion 1422 may be an elastic arm including a pawl. It is understandable that the second locking portion 1422 may also be a combination structure of a spring and a stopper, or a combination structure of a spring sheet and a stopper, and the present application embodiment does not limit this, as long as the second locking portion 1422 can be locked by the housing 150 when the hinge module 140 is in the closed position, and when the second locking portion 1422 is subjected to force, the second locking portion 1422 can be deformed to avoid the restriction of the housing 150.

[0106] The lock buckle 160 may be provided with a first groove structure on one side close to the first elastic member 110, and the first locking portion 161 may be a groove wall of the first groove structure for matching with the second end of the first elastic member 110. The unlocking portion 162 may be a groove wall of the second groove structure provided on one side of the lock buckle 160 facing the second locking portion 1422.

[0107] The second locking portion may be a portion between the first end and the second end of the first elastic member 110, or may be the second end of the first elastic member 110. The embodiment of the present application does not limit this, and the solution of the present application will be explained later by taking the second locking portion being the second end of the first elastic member 110 as an example. After the second end of the first elastic member 110 rotates to a certain extent driven by the lever 132, it can be locked with the first locking portion 161. Since the first end of the first elastic member 110 is fixedly connected to the hinge module 140, when the hinge module 140 is fixed, the operating shaft 130 drives the second end of the first elastic member 110 to rotate, and when the second end of the first elastic member 110 is locked with the first locking portion 161, the energy accumulated in the first elastic member 110 is stored, and the first elastic member 110 is in an energy storage state.

[0108] When the rotary switch 1 is in the closed state and the rotary switch 1 needs to be tripped and automatically opened, assuming that the lock buckle 160 is forced to move, on the one hand, the lock buckle 160 can release the lock on the second end of the first elastic member 110, and the second end of the first elastic member 110 will rotate to release the energy of the first elastic member 110. On the other hand, the lock buckle 160 can press the second locking portion 1422, so that the second locking portion 1422 is forced to deform, thereby avoiding the restriction of the housing 150. Among them, the action of the lock buckle 160 can be that the lock buckle 160 rotates or the lock buckle 160 moves horizontally. In addition, the deformation of the second locking portion 1422 can be that the second locking portion 1422 deforms in the direction close to the rotating shaft 142, or the second locking portion 1422 deforms in the direction of the second locking portion 1422 toward the inside of the aforementioned installation space. The form of the deformation of the second locking portion 1422 is related to the structural form of the second locking portion 1422, and the embodiment of the present application does not limit this.

[0109] Once the second locking portion 1422 avoids the restriction of the shell 150 and the lock buckle 160 releases the lock on the second end of the first elastic member 110, during the process of releasing energy of the first elastic member 110, the first end of the first elastic member 110 can drive the rotating shaft module 140 to rotate relative to the shell 150, and can drive the rotating shaft module 140 to rotate from the closed position to the open position.

[0110] In the embodiment of the present application, when the rotary switch 1 needs to be released and the lock 160 is actuated, the lock 160 can not only release the lock on the first elastic member 110, but also press the second locking portion 1422 to deform the second locking portion 1422, so as to release the restriction of the housing 150 on the second locking portion 1422. That is, when the rotary switch 1 needs to be released, the present application can realize double unlocking through the action of the lock 160. In this way, the first elastic member 110 can release energy freely, and the rotating shaft module 140 can be rotated from the closing position to the opening position only under the drive of the first elastic member 110, without being affected by whether the operating shaft 130 rotates or the size of the rotation resistance of the operating shaft 130. Therefore, even if the operating shaft 130 is deformed or aged, or the rotation resistance of the operating shaft 130 increases, and the torque of the operating shaft 130 cannot be effectively transmitted to the rotating shaft module 140, the rotary switch 1 can also be reliably and automatically opened, reducing the possibility of safety problems and improving the safety of the use of the rotary switch 1. Furthermore, the functions of the lock buckle 160 are enriched, so that the lock buckle 160 can be reused without additionally setting up other structural parts to release the restriction of the shell 150 on the second locking portion 1422, saving the number of structural parts used, thereby simplifying the structure of the operating mechanism 100.

[0111] Fig.15 This is a schematic diagram of the overall structure of a rotary switch provided in an embodiment of the present application. Fig.16 A schematic diagram of the structure of the cooperation relationship between the lock and the release system during the unlocking process of the lock and the first elastic member provided in an embodiment of the present application, combined with Figures 2 to 16 The rotary switch 1 includes a contact system 11, a tripping system 12 and the operating mechanism 100 in the aforementioned embodiment. The contact system 11 is connected to the shaft module 140 of the operating mechanism 100. The tripping system 12 cooperates with the operating mechanism 100. When the tripping system 12 is actuated, the rotary switch 1 can be automatically opened.

[0112] The contact system 11 can be connected to the rotating shaft 142 of the rotating shaft module 140. Specifically, the moving contact in the contact system 11 can be connected to the rotating shaft 142, so when the rotating shaft module 140 rotates, the rotating shaft 142 can rotate with the moving contact. When the moving contact rotates with the rotating shaft 142 to contact the static contact in the contact system 11, the rotary switch 1 is closed. Conversely, when the moving contact rotates with the rotating shaft 142 to separate from the static contact, the rotary switch 1 is opened. The connection method between the contact system 11 and the rotating shaft 142 can refer to the prior art and will not be described in detail here.

[0113] The tripping system 12 is located at one side of the operating mechanism 100. The tripping system 12 may include a flux converter or a tripping device, etc. The tripping system 12 cooperates with the operating mechanism 100 to push the lock 160 against the flux converter or the tripping device, and / or the flux converter or the tripping device pushes the second locking portion 1422 of the rotating shaft module 140.

[0114] The magnetic flux converter or releaser can directly push the lock buckle 160 or indirectly push the lock buckle 160, which is not limited in the embodiment of the present application. The magnetic flux converter or releaser can indirectly push the second locking portion 1422 through the lock buckle 160 or other intermediate structural parts.

[0115] When the magnetic flux converter or the release pushes the lock buckle 160, only the lock of the first elastic member 110 by the lock buckle 160 can be released, and in addition to releasing the lock of the first elastic member 110 by the lock buckle 160, the lock of the second locking portion 1422 by the housing 150 can also be released. When the magnetic flux converter or the release pushes the second locking portion 1422, the lock of the second locking portion 1422 by the housing 150 can be released.

[0116] In the present application, the automatic opening of the rotary switch 1 can be achieved by the elastic potential energy released by the first elastic member 110 to drive the rotation of the shaft module 140, and even if the rotation of the operating shaft 130 is obstructed so that the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110, the surplus elastic potential energy of the first elastic member 110 can also drive the shaft module 140 to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the safety of the use of the rotary switch 1.

[0117] Fig.17 A schematic diagram of a power distribution system provided in an embodiment of the present application is shown in FIG. Fig.17 As shown, an embodiment of the present application also provides a power distribution system, which includes a current detection device 2, a controller 3 and the rotary switch 1 in the aforementioned embodiment, and the current detection device 2, the controller 3 and the rotary switch 1 are electrically connected in sequence. The current detection device 2 is used to send a fault signal to the controller 3 when a preset fault is detected in the power distribution system. The controller 3 is used to receive the fault signal and generate a trip signal when the fault signal is received. The controller 3 is also used to send a trip signal to the rotary switch 1 to automatically open the rotary switch 1.

[0118] The current detection device 2 can be any device that can be used to detect the current in a circuit, such as an ammeter.

[0119] The controller 3 can be any device with automatic control function, such as a programmable logic controller 3 or a microcontroller 3 .

[0120] The preset fault may include at least one of string reverse connection, current backflow and bus short circuit.

[0121] The output end of the current detection device 2 can be connected to the input interface of the controller 3, and the output interface of the controller 3 can be connected to the control end of the rotary switch 1 to achieve sequential electrical connection of the current detection device 2, the controller 3 and the rotary switch 1.

[0122] Through the above electrical connection relationship, the current detection device 2 can send a fault signal to the controller 3 when detecting that there is a preset fault in the power distribution system. Correspondingly, the controller 3 can receive the fault signal sent by the current detection device 2, and generate a trip signal when receiving the fault signal, and send the trip signal to the trip system 12 of the rotary switch 1. The trip system 12 of the rotary switch 1 takes action when receiving the trip signal, so that the rotary switch 1 automatically opens. In the present application, the automatic opening of the rotary switch 1 can be achieved by the elastic potential energy released by the first elastic member 110 to drive the rotating shaft module 140 to rotate, and even if the second elastic member 120 absorbs the elastic potential energy released by the first elastic member 110 due to the obstruction of the rotation of the operating shaft 130, the surplus elastic potential energy of the first elastic member 110 can also drive the rotating shaft module 140 to rotate from the closing position to the opening position, thereby improving the reliability of the automatic opening of the rotary switch 1, thereby improving the use safety of the rotary switch 1.
