[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0029] The present invention provides an isolation indicating baffle structure, such as Figure 1-Figure 7 As shown, it includes a shell 1, and a bottom cover 2 is provided at the bottom of the shell 1 for easy disassembly and installation. Two hexagonal wrench entry holes 11 are provided at the lower part of one end of the shell 1 for easy entry of the hexagonal wrench. Two wiring holes 12 are provided at the upper part of one end of the shell 1 for wiring. An external wiring 3 is provided on the outer side of the wiring hole 12. The external wiring 3 is plugged into the wiring hole 12 for convenient wiring operation. A push-pull handle entry hole 14 is provided at one end of the shell 1 between the two hexagonal wrench entry holes 11, and a push-pull handle 4 is provided on the outer side of the push-pull handle entry hole 14; the push-pull handle 4 includes a handle 41, a movable block 42 is provided on one side of the handle 41, and push blocks 43 are provided on the upper and lower sides of the movable block 42. The push block 43 and the movable block 42 are an integrally formed structure, and a first inclined surface 431 is provided on one side surface of the push block 43. An isolation indicator plate 5 is provided on the inner side of 11, and a second inclined surface 53 is provided on the side of the isolation indicator plate 5 close to the push block 43. A spring fixing groove 51 is provided on the side of the inner wall of the isolation indicator plate 5 close to the outer shell 1, and a reset spring 52 is provided inside the spring fixing groove 51. A wire clamping frame connector 6 is provided on both sides of the push-pull handle 4 inside the outer shell 1. Normally, the isolation indicator plate 5 can block the hexagonal wrench entry hole 11 to prevent the hexagonal wrench from entering and ensure electrical isolation. When the push-pull handle 4 is pushed inward, the push block 43 pushes the isolation indicator plates 5 on both sides to move outward, thereby removing the isolation indicator plate 5 from the hexagonal wrench entry hole 11, so that the hexagonal wrench entry hole 11 is opened. At this time, the inner end of the external wire 3 can be tightened or loosened by inserting the hexagonal wrench into the hexagonal wrench entry hole 11, which is convenient for power-on and power-off operations.

[0030] Specifically, a positioning hole 13 is opened on the top of the housing 1 , and a housing rivet 131 is vertically arranged inside the positioning hole 13 to facilitate the assembly of the housing 1 .

[0031] In addition, the handle 41 and the movable block 42 are integrally formed to ensure that the handle 41 will not break when in use.

[0032] Furthermore, one end of the return spring 52 is in close contact with the inner wall of the housing 1 , which can ensure that the return spring 52 is fixed so that its position will not shift.

[0033] Furthermore, a limiting hole 44 is provided in the middle of the movable block 42, and the limiting hole 44 is in a strip-shaped structure. The middle of the shell rivet 131 passes through the limiting hole 44, which can limit the range of motion of the movable block 42 and avoid excessive squeezing of the isolation indicator plate 5 to both sides to cause damage.

[0034] Furthermore, the inner walls at both ends of the limiting hole 44 are arcuate structures. When the inner walls at both ends of the limiting hole 44 contact the outer wall of the shell rivet 131 , the smooth structures at both ends can prevent the shell rivet 131 from being worn.

[0035] Furthermore, the width of the handle 41 is greater than the width of the movable block 42 , which facilitates the gripping of the handle 41 .

[0036] Furthermore, the clamping frame connector 6 includes a fixed shell 61, a lower block 64 is slidably arranged inside the fixed shell 61, a threaded hole 641 is provided on one side of the lower block 64, a hexagonal bolt 65 is threadedly connected to the threaded hole 641, a round hole 611 is provided on the outer wall of one side of the fixed shell 61 close to the hexagonal bolt 65, the diameter of the round hole 611 is smaller than the diameter of the end of the hexagonal bolt 65, the length of the hexagonal bolt 65 is adapted to the size of the inner wall space of the fixed shell 61, an upper block 63 is provided on the upper part of the lower block 64, a reset spring 66 is provided on the top of the upper block 63, an inclined surface is provided on the top of the lower block 64, and an inclined surface is provided on the bottom of the upper block 63. The rotation of the hexagonal bolt 65 can drive the lower block 64 to move horizontally, thereby causing the upper block 63 to move up and down. The up and down movement of the upper block 63 can drive the reset spring piece 66 to move upward to tighten the inner end of the external wire 3. When the hexagonal wrench enters the round hole 611, one end is connected to the hexagonal bolt 65. When the hexagonal wrench is rotated, the hexagonal bolt 65 rotates, thereby driving the lower block 64 to move horizontally, thereby causing the upper block 63 to move vertically, pushing the reset spring piece 66 upward, and the reset spring piece 66 tightens the inner end of the external wire 3 to achieve power-on operation. When the hexagonal bolt 65 is rotated in the opposite direction, the inner end of the external wire 3 can be loosened to achieve power-off operation.

[0037] Furthermore, a non-detachable cover plate 62 is provided on one side of the fixed shell 61 and is riveted together to fix the internal structural parts in the shell.

[0038] Furthermore, the inner walls on both sides of the fixed shell 61 are respectively provided with horizontal and vertical strip holes, and the outer walls on both sides of the lower block 64 and the upper block 63 are provided with protrusions. The lower block 64 slides horizontally inside the fixed shell 61 through the cooperation of the protrusions and the strip holes, and the upper block 63 slides vertically inside the fixed shell 61 through the cooperation of the protrusions and the strip holes, which can ensure that the movement of the lower block 64 and the upper block 63 is stable and will not deviate.

[0039] When the isolation indicator baffle structure of this embodiment is used, the push-pull handle 4 is pushed inward (ON position), so that the isolation indicator plate 5 moves to both sides, the hexagonal wrench access hole 11 is closed to play the role of electrical isolation, and the hexagonal wrench access hole 11 is closed when the power is turned on by the isolation indicator plate 5; the push-pull handle 4 is pulled outward (OFF position), and the reset spring 52 resets the isolation indicator plate 5 to the middle, exposing the hexagonal wrench access hole 11, and then the hexagonal wrench enters through the hexagonal wrench access hole 11, and the hexagonal wrench is rotated to move the reset spring 66 up and down, loosening or pressing the inner end of the external wire 3, and realizing the connection and removal of the external wire. That is: the external wire can be connected or removed only after the power is turned off, and the isolation indicator plate plays an isolation role when the power is on.
