Description
Technical Field
[0001] The utility model relates to the technical field of isolating switches, and in particular to an isolating mechanism and a switch device. Background Art
[0002] With the widespread use of electricity today, circuit breakers are often installed to ensure safe operation. These switches allow for closing, opening, and grounding of circuits. Closing the circuit connects it to the ground; opening the circuit disconnects it; and grounding the circuit grounds it to the earth.
[0003] In the prior art, the isolating switch is usually placed inside a preset box. However, when the isolating switch is in the closed state, that is, the circuit is in the on state, if the isolating switch is operated directly, there is a risk of electric shock, which reduces the operator's operating safety. Utility Model Content
[0004] The technical problem solved by the utility model is how to improve the problem of low safety in operating the isolating switch in the prior art.
[0005] The embodiment of the present utility model can be implemented as follows:

[0013] The isolation mechanism provided by the present invention has the following beneficial effects compared with the prior art:
[0014] When the isolation mechanism is applied to a circuit, when the isolation mechanism is in the closed state or the open state, the interlocking mechanism locks the chamber door; and in the process of grounding, the operator operates the first rotating shaft to rotate, and the transmission structure transmits power to the second rotating shaft, realizing the rotation of the second rotating shaft, thereby achieving grounding.

This means that when the isolation mechanism is in the closed state or the open state, the cable chamber door cannot be opened, and the isolation mechanism cannot be operated; the chamber door can only be opened to operate the isolation mechanism when the isolation mechanism is grounded, thereby preventing the operator from operating the isolation mechanism in the closed state or the open state, effectively avoiding the risk of electric shock to the operator, and improving the operator's operating safety. Based on this, the isolation mechanism provided by the utility model can improve the problem of low safety in operating the isolating switch in the prior art.

[0016] Optionally, the interlocking mechanism further includes an elastic member, which is connected to the rotating part. When the trigger end is moved by the toggle member, the rotating part drives the elastic member to move and generate elastic deformation; the elastic member is also used to drive the interlocking mechanism to reset when the toggle member moves away from the trigger end, so as to unlock the door.
[0017] Optionally, the isolating switch further comprises a limit member, which is fixedly connected to the bearing body and is located on the rotation path of the trigger end; the limit member is used to abut against the trigger end after the interlocking mechanism is reset and the door is locked.

[0036] Please refer to Figures 1 to 3 This embodiment provides an isolation mechanism 10 and a switch device using the isolation mechanism 10. The isolation mechanism 10 and the switch device can be used in a circuit to connect and disconnect the circuit, that is, to close and open the circuit. The isolation mechanism 10 and the switch device can improve the low safety problem of operating isolation switches in the prior art.
[0037] In this embodiment, the isolation mechanism 10 includes a carrier body 100, a first rotating shaft 200, a second rotating shaft 300, a rotating member 400, a toggle member 500, and an interlocking mechanism 600. The first rotating shaft 200 is rotatably connected to the carrier body 100. The second rotating shaft 300 is rotatably connected to the carrier body 100 and is in transmission connection with the first rotating shaft 200 via a transmission structure; the second rotating shaft 300 is used to perform closing, opening, and grounding operations. The rotating member 400 is fixed to the second rotating shaft 300 to rotate with it. The toggle member 500 is eccentrically mounted on the rotating member 400 to rotate with it. The interlocking mechanism 600 can be movably arranged on the supporting body 100. The interlocking mechanism 600 is used to be connected to the door of the cable room where the isolation mechanism 10 is located, and lock the door when the isolation mechanism 10 is in a closed state or an open state, so that the door cannot be opened; the interlocking mechanism 600 has a trigger end 601, and the trigger end 601 is arranged on the rotation path of the toggle member 500; the trigger end 601 is used to be toggled by the toggle member 500 during the grounding process, and after the second rotating shaft 300 performs grounding, the interlocking mechanism 600 unlocks the door of the cable room where the isolation mechanism 10 is located.
[0038] in, Figure 1 is a schematic diagram of the isolation mechanism 10 in a grounded state; Figure 2 FIG. 1 is a schematic diagram of the isolation mechanism 10 in a closed state.
[0039] As described above, when the isolation mechanism 10 is applied to a circuit, the interlocking mechanism 600 locks the door when the isolation mechanism 10 is in the closed or open state. During grounding, the operator rotates the first rotating shaft 200, and the transmission structure transmits power to the second rotating shaft 300, causing the second rotating shaft 300 to rotate and thereby achieve grounding. During the rotation of the second rotating shaft 300, the rotating member 400 is simultaneously driven to rotate, and the rotating member 400 drives the toggle member 500 to rotate. This allows the toggle member 500 to toggle the trigger end 601 during grounding, triggering the interlocking mechanism 600 to unlock the door, thereby unlocking the cable compartment door. This means that when the isolation mechanism 10 is in the closed or open state, the cable compartment door cannot be opened, and the isolation mechanism 10 cannot be operated. The door can only be opened to operate the isolation mechanism 10 when the isolation mechanism 10 is grounded, preventing the operator from operating the isolation mechanism 10 in the closed or open state, effectively avoiding the risk of electric shock to the operator and improving the operator's operating safety. Based on this, the isolation mechanism 10 provided in this embodiment can improve the low safety problem of operating the isolation switch in the prior art.
[0040] Optionally, in this embodiment, the interlocking mechanism 600 includes a rotating part 610 and a connecting rod assembly 620; the rotating part 610 is rotatably connected to the carrying body 100, and the connecting rod assembly 620 is used to connect with the door; one end of the rotating part 610 forms a trigger end 601, and the other end is connected to the connecting rod assembly 620; when the trigger end 601 is toggled by the toggle member 500, the rotating part 610 drives the connecting rod assembly 620 to move to unlock the door.
[0041] That is to say, when the toggle member 500 drives the rotating part 610 to rotate, the rotating part 610 simultaneously drives the connecting rod assembly 620 to move, thereby transmitting power to the locking structure of the door through the connecting rod assembly 620 to unlock the door.
[0042] Furthermore, in order to facilitate the locking of the door, in this embodiment, the interlocking mechanism 600 also includes an elastic member 630, which is connected to the rotating part 610. When the trigger end 601 is moved by the toggle member 500, the rotating part 610 drives the elastic member 630 to move and produce elastic deformation; the elastic member 630 is also used to drive the interlocking mechanism 600 to reset when the toggle member 500 moves away from the trigger end 601, so as to achieve locking of the door.
[0043] Specifically, during grounding, the toggle member 500 toggles the trigger end 601, causing the rotating portion 610 to rotate and, at the same time, elastically deforming the elastic member 630. During closing or opening, the toggle member 500 moves away from the trigger end 601, removing the force inhibiting the elastic member 630. The elastic member 630, through its elastic recovery, drives the rotating portion 610 to rotate back to its original position, transmitting power to the connecting rod assembly 620 to automatically lock the door. This allows the door to be automatically locked during closing and opening, and automatically unlocked during grounding, providing convenient operation and high safety.
[0044] Optionally, in this embodiment, the elastic member 630 may be a torsion spring, which is sleeved on the central axis of rotation of the rotating portion 610. Of course, in other embodiments, the elastic member 630 may also have other structures. For example, a flexible elastic member 630 may be used to connect the rotating portion 610 and the carrier body 100. During the rotation of the rotating portion 610, the elastic member 630 may be stretched. When the toggle member 500 is removed from the trigger end 601, the elastic member 630 retracts to drive the rotating portion 610 to return to rotation, thereby locking the door through the connecting rod assembly 620.
[0045] In this embodiment, the isolating switch further includes a stopper 640, which is fixedly connected to the carrier body 100 and located in the rotational path of the trigger end 601. The stopper 640 is used to abut the trigger end 601 after the interlocking mechanism 600 resets and the door is locked. As the elastic member 630 drives the rotating portion 610 to reset and rotate, the trigger end 601 rotates until it abuts against the stopper 640, thus limiting the position of the rotating portion 610. This not only prevents the rotating portion 610 from excessive rotation, but also restricts the rotating portion 610 to a position that can cooperate with the toggle member 500. This facilitates the toggle member 500 to drive the rotating portion 610 to rotate during the grounding operation, thereby facilitating subsequent door unlocking.
[0046] Optionally, in this embodiment, the toggle member 500 and the limiting member 640 are both bolt structures, that is, the toggle member 500 is a bolt structure arranged on the rotating member 400 by a threaded connection, and the limiting member 640 is a bolt structure arranged on the supporting body 100 by a threaded connection.
[0047] Of course, in other embodiments, the toggle member 500 and the limiting member 640 may also be arranged in other ways, for example, the toggle member 500 and the rotating member 400 are integrally formed; the limiting member 640 and the carrying body 100 are integrally formed, etc.
[0048] In this embodiment, the rotating portion 610 includes a rotating connection portion 611 and a trigger portion 612; the middle portion of the rotating connection portion 611 is rotatably connected to the carrier body 100, and the trigger portion 612 is provided at one end of the rotating connection portion 611 and is provided at an angle to the rotating connection portion 611, and the trigger portion 612 forms the trigger end 601. Figure 3 For example, it can be seen that the trigger portion 612 is a downwardly extending structure, which can facilitate the abutment between the toggle member 500 and the trigger portion 612, and also facilitate the toggle member 500 to drive the rotating portion 610 to rotate.
[0049] In addition, the rotating portion 610 further includes an extension portion 613, which is disposed at one end of the rotating connecting portion 611 away from the trigger portion 612 and is disposed at an angle to the rotating connecting portion 611. The extension portion 613 is connected to the connecting rod assembly 620. Figure 3 For example, the extension portion 613 extends upward to facilitate connection with the connecting rod assembly 620, thereby reducing assembly difficulty.
[0050] In this embodiment, the connecting rod assembly 620 includes at least one connecting rod 621, one end of which is connected to the rotating portion 610, and one of the connecting rods 621 is used to connect to the door. Figure 1 and Figure 2In this example, the connecting rod 621 structure includes only one connecting rod 621, one end of which is connected to the rotating portion 610, and the other end is used to connect to the locking structure of the door. In other embodiments of the present application, the connecting rod assembly 620 may also include multiple connecting rods 621, and the multiple connecting rods 621 can form a multi-link 621 structure to drive the door locking structure.
[0051] In this embodiment, the rotating member 400 is disc-shaped, and the toggle member 500 is provided with a protrusion on one side of the thickness direction of the rotating member 400. The disc-shaped rotating member 400 can reduce the space occupied by the rotating member 400 in the carrier body 100, which is conducive to the miniaturization of the isolation mechanism 10 and reduces the space required for the isolation mechanism 10. In turn, the isolation mechanism 10 is not restricted by the installation space, thereby achieving the purpose of expanding the application scenarios of the isolation mechanism 10.
[0052] In this embodiment, the transmission structure includes a first gear 210 and a second gear 310. The first gear 210 is fixedly connected to the first rotating shaft 200, and the second gear 310 is fixedly connected to the second rotating shaft 300. The first gear 210 and the second gear 310 are meshed. The transmission connection between the first rotating shaft 200 and the second rotating shaft 300 is achieved through gear meshing. On the one hand, it can ensure the stability of the transmission connection. On the other hand, due to the higher stability of the gear transmission, it can more accurately complete the closing, opening, and grounding operations, and simultaneously accurately achieve the interlocking of the door.
[0053] Based on the isolation mechanism 10 provided above, the switch device provided in this embodiment adopts the isolation mechanism 10. Based on this, the switch device can also improve the problem of low safety in operating the isolation switch in the prior art.
[0054] In summary, when the isolation mechanism 10 is applied to a circuit, the interlocking mechanism 600 locks the door when the isolation mechanism 10 is in the closed or open state. During grounding, the operator rotates the first rotating shaft 200, and the transmission structure transmits power to the second rotating shaft 300, causing the second rotating shaft 300 to rotate and thereby achieve grounding. During the rotation of the second rotating shaft 300, the rotating member 400 is simultaneously driven to rotate, and the rotating member 400 drives the toggle member 500 to rotate. This allows the toggle member 500 to toggle the trigger end 601 during grounding, triggering the interlocking mechanism 600 to unlock the door, thereby unlocking the cable compartment door. This means that when the isolation mechanism 10 is in the closed or open state, the cable compartment door cannot be opened, and the isolation mechanism 10 cannot be operated. The door can only be opened to operate the isolation mechanism 10 when the isolation mechanism 10 is grounded, preventing the operator from operating the isolation mechanism 10 in the closed or open state, effectively avoiding the risk of electric shock to the operator and improving the operator's operating safety. Based on this, the isolation mechanism 10 provided in this embodiment can improve the low safety problem of operating the isolation switch in the prior art. Furthermore, during the grounding process, the toggle member 500 toggles the trigger end 601, causing the rotating portion 610 to rotate, while simultaneously achieving elastic deformation of the elastic member 630. During closing and opening, the toggle member 500 moves away from the trigger end 601, canceling the force that suppresses the elastic member 630. The elastic member 630, through its elastic recovery action, drives the rotating portion 610 to rotate and reset, thereby transmitting power to the connecting rod assembly 620 to achieve automatic locking of the compartment door. Based on this, the door can be automatically locked during closing and opening, and automatically unlocked during grounding, providing convenient operation and high safety. Furthermore, as the elastic member 630 drives the rotating portion 610 to reset and rotate, the trigger end 601 rotates until it abuts against the limiting member 640, completing the position limit of the rotating portion 610. This not only prevents the rotating portion 610 from rotating excessively, but also restricts the rotating portion 610 to a position that can cooperate with the toggle member 500. This facilitates the toggle member 500 to drive the rotating portion 610 to rotate during the grounding operation, facilitating subsequent door locking.
[0055] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
