[0027] Schematic diagram of the interlocking structure between the switchgear circuit breaker and the isolator

[0028] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, the interlocking structure between the circuit breaker and the isolator of the switch cabinet is a shaft blocking structure located in the switch cabinet. It should be noted that the existing switch cabinet includes a connecting plate 10, a first rotating shaft 20 and a second rotating shaft 30. The first rotating shaft 20 and the second rotating shaft 30 are both rotatably arranged on the connecting plate 10, and the first rotating shaft 20 and the second rotating shaft 30 are spaced a predetermined distance apart. The present invention is placed between the first rotating shaft 20 and the second rotating shaft 30. In addition, the present invention is configured to rotate a predetermined angle to block the second rotating shaft 30. It should be noted that the existing method of installing the shaft blocking structure is as follows: Figure 5As shown, it includes a first rotating member 40 and a fastening assembly 50, the fastening assembly 50 includes a connecting shaft 51, a gasket 52 and a nut 53, one end of the connecting shaft 51 is threadedly connected to the connecting plate 10, and the end of the connecting shaft 51 away from the connecting plate 10 has a connecting end, the first rotating member 40 cooperates with the connecting end and abuts against the side of the connecting shaft 51 close to the connecting end, and then the gasket 52 is sleeved on the connecting end and contacts with the side of the first rotating member 40 away from the connecting plate 10, while the nut 53 is threadedly connected to the connecting end and contacts the gasket 52, thereby limiting the position of the first rotating member 40. However, in actual use, since the first rotating member 40 needs to rotate back and forth by a predetermined angle, the nut 53 on the gasket 52 is more likely to loosen, so that the nut 53 cannot completely define the position of the first rotating member 40, and the first rotating member 40 is tilted, which makes the existing shaft blocking structure ineffective. Therefore, the user needs to replace the first rotating member 40. Since the connecting shaft 51 is threadedly connected to the connecting plate 10, when the structure is not maintained for a long time, its thread structure will produce a stuck phenomenon, making it difficult to disassemble the connecting shaft 51. Therefore, it is necessary to improve the existing shaft blocking structure. The following is a detailed explanation of the present invention to facilitate understanding of the present invention.

[0029] Specifically, the interlocking structure between the switchgear circuit breaker and the isolator includes a second rotating member 60, which has a first connecting wall 61, an extension wall 62, and a shielding wall 63. One end of the first connecting wall 61 is connected to one end of the extension wall 62, and the other end of the extension wall 62 is connected to the shielding wall 63. It should be noted that the first connecting wall 61 is perpendicular to the extension wall 62 and is also parallel to the shielding wall 63. That is, the first connecting wall 61, the extension wall 62, and the shielding wall 63 are integrally formed, and the second rotating member 60 is Z-shaped.

[0030] Specifically, the interlocking structure between the switchgear circuit breaker and the isolator further includes a connector 70, which passes through the connecting plate 10 and is located between the first rotating shaft 20 and the second rotating shaft 30. It should be noted that one end of the connector 70 passes through the connecting plate 10 and is rotatably mounted on the connecting plate 10, while the other end is fixedly connected to the second rotating member 60. It is worth mentioning that the connector 70 includes a first connecting portion 71, an abutting portion 72, and a second connecting portion 73. The abutting portion 72 has two ends connected to the first connecting portion 71 and the second connecting portion 73, respectively. The second connecting portion 73 passes through the connecting plate 10, and the abutting portion 72 is in contact with the connecting plate 10.

[0031] Furthermore, the first connecting wall 61 has a first insertion hole 6101 that extends through the first connecting wall 61. The first connecting portion 71 is positioned within the first insertion hole 6101. The side of the abutting portion 72 facing away from the second connecting portion 73 is fixedly connected to the first connecting wall 61. It is worth noting that when the second rotating member 60 rotates, the connecting member 70 rotates accordingly. The connection between the first connecting wall 61 and the abutting portion 72 can be implemented as a welded connection.

[0032] It is worth mentioning that the second connecting part 73 also has an assembly hole 7301, and the assembly hole 7301 passes through the second connecting part 73. In addition, the connecting plate 10 has a second insertion hole 101, and the wall surface forming the connecting plate 10 has an annular groove 102, wherein when the second connecting part 73 passes through the second insertion hole 101, the annular groove 102 is opposite to the assembly hole 7301.

[0033] Specifically, the interlocking structure between the switch cabinet circuit breaker and the isolation also includes a telescopic component 80, which can be telescopically placed in the assembly hole 7301, wherein when the annular groove 102 is opposite to the assembly hole 7301, the two ends of the telescopic component 80 are respectively placed in the annular groove 102, thereby limiting the position of the second connecting part 73.

[0034] The assembly hole 7301 has two large holes and one small hole. Both ends of the small hole are respectively connected to the two large holes, and the two large holes are respectively located on both sides of the second connecting portion 73.

[0035] Furthermore, the telescopic assembly 80 includes two moving parts 81 and an elastic part 82. The two moving parts 81 are movably placed in the two large holes, and the elastic part 82 is placed in the small hole. At the same time, the two ends of the elastic part 82 are respectively matched with the ends of the moving parts 81 that are close to each other, and are preferably connected by a snap connection. Figure 4As shown, the ends of the two moving members 81 that are close to each other have two oppositely arranged protrusions 8121, and the two ends of the elastic member 82 are respectively connected to the two protrusions 8121, and at the same time, the ends of the two moving members 81 that are close to each other are both sleeve-connected with the elastic member 82. Specifically, when the user presses the two moving members 81, the two moving members 81 are placed in the corresponding large holes. At this time, the second connecting portion 73 can pass through the second insertion hole 101 until the annular groove 102 is opposite to the assembly hole 7301. At this time, the two moving members 81 move a predetermined distance in the direction of separation from each other, that is, the ends of the two moving members 81 that are separated from each other are both placed in the annular groove 102, thereby limiting the position of the second connecting portion 73, and at this time, the second connecting portion 73 can rotate in the second insertion hole 101.

[0036] Furthermore, the movable member 81 has a limiting portion 811 and a third connecting portion 812, the limiting portion 811 is connected to the third connecting portion 812, and one end of the limiting portion 811 close to the third connecting portion 812 is placed in the corresponding large hole, and the other end is placed in the annular groove 102, and the end of the third connecting portion 812 away from the limiting portion 811 cooperates with the elastic member 82. In summary, the present invention can be assembled by quick plugging during the installation process, which is more efficient than the existing installation method. In addition, the present invention rotates synchronously, so there will be no problem of the second rotating member 60 and the connecting member 70 being unreliable, and therefore the shielding portion will not be unable to block the second rotating shaft 30.

[0037] In summary, the interlocking structure between the switch cabinet circuit breaker and the isolator based on the embodiment of the present application is explained, which provides the interlocking structure between the switch cabinet circuit breaker and the isolator with advantages such as convenient disassembly and assembly, simple structure, and high practicality.

[0038] It is worth mentioning that in the embodiments of the present application, the interlocking structure between the switchgear circuit breaker and the isolator is simple in structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the interlocking structure between the switchgear circuit breaker and the isolator provided in the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further promoting product promotion and use.
