With the development of circuit breaker technology, more demands are being placed on accessories of the circuit breaker. The energy storage electric operation is an important component in the circuit breaker. The energy storage electric operation can display the working state of the circuit breaker, and is an important requirement for the development of the energy storage electric operation. In the prior art, energy storage electric operations have a mechanism for identifying the operating state of a circuit breaker. The mechanism generally interacts with the handle of the circuit breaker to obtain the operating state of the circuit breaker. However, this mechanism is only suitable for use on a portion of the product. For this reason, in order to diversified satisfying market demand, this application proposes a pivot link gear, and it is rotated when switching frock state to the pivot and is transmitted power to the mechanism that is used for the sign circuit breaker operating condition to be used for energy storage electricity to operate the operating condition who shows the circuit breaker.

Specifically, referring to fig. 1 to 4, the present application proposes a spindle linkage 100, which includes a base 110, a spindle 120, a cover 130, and a first ejector 140. The rotating shaft 120 is rotatably mounted on the base 110, and the rotating shaft 120 is rotatably mounted on the base 110. The cover 130 is connected to the base 110, and is used for installing the stored energy electric operation 300. As shown in fig. 5 and 6, the cover 130 is provided with a guide hole 130a. The first ejector 140 is movably connected to the rotating shaft 120. As shown in fig. 2 to 4, the first push rod 140 penetrates into the guide hole 130a and is in sliding contact with the hole wall of the guide hole 130a, so that when the rotating shaft 120 rotates in a preset direction, the first push rod 140 can move along the axial direction of the guide hole 130a to touch the indicating mechanism of the stored energy electric operation 300.

In the technical solution of the embodiment of the present application, the rotating shaft 120 is rotatably installed on the base 110; the base 110 is provided with a cover 130, and the cover 130 is used for installing an indicating mechanism of the energy storage electric operation 300; the cover 130 is provided with a guide hole 130a; the first ejector rod 140 movably connected to the rotating shaft 120 penetrates into the guide hole 130a and is in sliding contact with the guide hole 130a, when the rotating shaft 120 rotates along the preset direction, the first ejector rod 140 can move in the axial direction of the guide hole 130a to touch the energy storage electric operation 300, and power is transmitted to the energy storage electric operation 300, so that the energy storage electric operation 300 can display the current working state of the circuit breaker 10 based on the collision of the first ejector rod 140. In the technical scheme of the application, through the rotation of the rotating shaft 120, the first ejector rod 140 is driven to touch the energy storage electric operation 300 so that the energy storage electric operation 300 displays the working state information of the circuit breaker 10, and diversified development requirements are provided for the circuit breaker 10.

In an embodiment, the preset direction generally refers to: when the circuit breaker 10 is switched from the closed state to the open state, the rotation direction of the rotation shaft 120. For example, the preset direction is counter-clockwise rotation. For example, in some embodiments, the axial direction of the pilot hole 130a is parallel to the vertical direction; during the closing process of the circuit breaker 10, the rotating shaft 120 rotates clockwise to drive the first ejector rod 140 to move downwards. In the opening process of the circuit breaker 10, the rotating shaft 120 rotates anticlockwise, the first ejector rod 140 ascends, and the energy storage electric operation 300 is touched to display the opening state.

As an alternative to the above embodiment, as shown in fig. 7 to 9, the rotating shaft 120 includes an extension body 121 disposed offset from an axis thereof. As shown in fig. 9, the extension body 121 is provided with a chute 121a. As shown in fig. 8, the first ejector 140 includes a sliding body 141, and the sliding body 141 is slidably disposed in the chute 121a. When the rotating shaft 120 rotates, the extension body 121 performs a rotational motion around its axis; the slide groove 121a follows the movement of the extension body 121 to generate a positional change in the circumferential direction. In the embodiment, since the hole wall of the guide hole 130a limits the movement direction of the first ejector rod 140 to move along the axial direction of the guide hole 130a, when the position of the sliding slot 121a is changed, the sliding body 141 slides in the sliding slot 121a in a self-adaptive manner, so as to avoid the first ejector rod 140 from being blocked.

As an alternative to the above embodiment, the sliding groove 121a extends along a radial direction of the rotating shaft 120. When the rotating shaft 120 rotates along the preset direction, the sliding groove 121a follows the extending body 121 to rotate, the sliding groove 121a gradually rises, and the sliding body 141 slides along the extending direction of the sliding groove 121a, and the first ejector 140 pushes the first ejector 140 to move in the axial direction of the guiding hole 130a based on the acting force of the groove wall of the sliding groove 121a to touch the stored energy electric operation 300.

As an alternative implementation of the above embodiment, as shown in fig. 10 and fig. 2 to 3, the first ejector 140 further includes a first section 142 and a second section 143 sequentially disposed along the axial direction of the guide hole 130a; the sliding body 141 is disposed on the first section 142, and the second section 143 is used for touching the stored energy electric operation 300. Generally, the second section 143 extends out of the cover 130 from within the guide hole 130a and is in sliding contact with the wall of the guide hole 130a. In the exemplary embodiment, the sliding body 141 can be connected to the first section 142 in a rotary manner or can be connected to the first section 142 in a fixed manner. If the sliding body 141 is rotatably connected to the first section 142, the sliding body 141 may be rubbed against the groove wall of the slide groove 121a by rolling when the rotation shaft 120 rotates, so that the abrasion of the sliding body 141 may be reduced. If the sliding body 141 is fixedly connected to the first section 142, the sliding body 141 slides against the groove wall of the slide groove 121a when the rotation shaft 120 rotates.

In an embodiment, the first section 142 and the second section 143 are generally one piece.

As an alternative to the above embodiment, as shown in fig. 10, the sliding body 141 is configured as a revolving body. In an embodiment, the sliding body 141 may be configured in a cylindrical, spherical, or truncated cone shape. The sliding body 141 is configured as a revolving structure, and is mainly used in a structure in which the sliding body 141 is rotatably connected with the first section 142, so that the sliding body 141 rotates while sliding in the sliding groove 121a, and the first ejector rod 140 moves stably without jamming.

As an alternative to the above-described embodiment, the sliding body 141 is provided on the side of the first section 142 facing the extension body 121. The first section 142 is in contact with the extension body 121. Generally, the first section 142 is in surface contact with the extension 121. Placing the first section in contact with the extension 121 helps guide and straighten the first ram 140, avoiding jamming of the first ram 140 from affecting the positioning of the first ram 140.

The circuit breaker 10 also typically includes an accessory for assistance/alarm. The auxiliary/alarm accessory includes a microswitch 200. For this purpose, in the embodiment of the present application, as shown in fig. 8 and fig. 4, the rotating shaft 120 includes a touch protrusion 122, and the touch protrusion 122 is configured on the extension body 121. The cover 130 is provided with a second ejector rod 131. When the rotating shaft 120 rotates along the preset direction, the touching protrusion 122 pushes the second ejector rod 131 to trigger the micro switch 200 mounted on the cover 130. In the process that the rotation shaft 120 rotates along the preset direction, the touching protrusion 122 touches the second ejector rod 131, and pushes the second ejector rod 131 to trigger the micro switch 200, so that the auxiliary/alarm accessory can identify the working state of the circuit breaker 10, and further output a signal for switching the working state of the circuit breaker 10. Typically, the micro-switch 200 in the auxiliary/alarm accessory is disposed in a mounting slot of the cover 130. The cover 130 is provided with a hole communicating with the installation groove. One end of the second ejector rod 131 extends from the hole into the micro switch 200; in an embodiment, the other end of the second jack 131 is located on the movement track of the touch protrusion 122, so that the second jack 131 can be pushed up by the touch protrusion 122.

In an embodiment, during the closing process of the product, the rotating shaft 120 rotates in the opposite direction of the preset direction, so as to disengage the function of the antenna of the auxiliary/alarm accessory, and simultaneously the first push rod 140 moves downwards; in the process of opening the switch, the rotating shaft 120 rotates anticlockwise, the touch protrusion 122 pushes up to the second ejector rod 131, triggers the micro switch 200 to output a signal, drives the first ejector rod 140 to ascend, and touches the energy storage electric operation 300 to enable the energy storage electric operation 300 to display the switch-off state.

Depending on the arrangement of the stored energy power operation 300 and the auxiliary/warning attachment on the cover 130, as an alternative to the above-described embodiment, the contact protrusion 122 and the sliding groove 121a are arranged on the extension body 121 in a staggered manner in the axial direction of the shaft 120. In the embodiment, the movement track of the touching protrusion 122 and the movement track of the sliding groove 121a are offset from each other in the axial direction of the rotating shaft 120, so that the auxiliary/alarm accessory and the stored energy power operation 300 can be triggered at the same time.

In some embodiments, the extension 121 has a first side and a second side. The normal direction of the first side is parallel to the axial direction of the rotation shaft 120. The normal direction of the second side is parallel to the radial direction of the rotation shaft 120. The chute 121a is a structure with a notch formed on the first side and recessed into the extension body 121. The touch protrusion 122 is protruding from the second side surface.

As an alternative implementation of the above embodiment, as shown in fig. 11, a guide groove 110a is formed on the base 110, and a groove wall of the guide groove 110a is in sliding contact with the first ejector 140. In an embodiment, the base 110 includes a bottom plate and a plurality of support plates disposed on the bottom plate. The rotating shaft 120 is rotatably disposed on the support plate. The support plate is provided with a guide groove 110a, and the first push rod 140 is in sliding contact with a groove wall of the guide groove 110a, so that the first push rod 140 moves smoothly and has a direction. In general, the first section 142 of the first jack 140 is in sliding contact with the groove wall of the guide groove 110a and the extension body 121 on opposite sides thereof in the thickness direction.

As shown in fig. 12 and 13, the present application further proposes a circuit breaker 10 including an energy storage electric operation 300 and a spindle linkage 100. The spindle linkage mechanism 100 adopts a part of or all of the structures in the foregoing embodiments, so that it has a part of or all of the technical advantages of the foregoing embodiments, and will not be described in detail herein. In an embodiment, the stored energy operation 300 is mounted on the cover 130. The stored energy operation 300 has a mechanism for identifying the operating condition of the circuit breaker 10. In the embodiment, the energy storage electric operation 300 is disposed on a side of the cover 130 facing away from the rotating shaft 120, and is disposed corresponding to the guide hole 130a.

In an embodiment, the guide hole 130a defines a moving direction of the first jack 140. When the rotation shaft 120 rotates, the first push rod 140 moves along the axial direction of the guide hole 130a. The energy storage electric operation 300 is disposed corresponding to the guide hole 130a, so that the first ejector rod 140 can touch a mechanism on the energy storage electric operation 300 for identifying the working state of the circuit breaker 10. Generally, when the circuit breaker 10 is in the opening state, the first ejector 140 touches the mechanism on the energy storage electric operation 300 for identifying the working state of the circuit breaker 10, so that the energy storage electric operation 300 displays that the working state of the circuit breaker 10 is the opening state; when the circuit breaker 10 is in the closed state, the first ejector 140 is disengaged from the mechanism on the energy storage electric operation 300 for identifying the working state of the circuit breaker 10, so that the energy storage electric operation 300 displays that the working state of the circuit breaker 10 is in the closed state.

In an embodiment, the energy storage electric operation 300 is disposed corresponding to the guide hole 130a as follows: in the same projection plane perpendicular to the axial direction of the guide hole 130a, the first plunger 140 coincides with a mechanism on the stored energy operator 300 for identifying the operating state of the circuit breaker 10.
