[0025] like Figure 1 , Figure 3 As shown, a leakage indication device for a small leakage circuit breaker comprises a leakage circuit breaker body 1, a toggle switch 2 and a reset button 3 are arranged on the front of the leakage circuit breaker body 1, a fixing box 4 is arranged on the front side of the leakage circuit breaker body 1, a locking component 5 for connecting the leakage circuit breaker body 1 and the fixing box 4 is arranged on the surface of the fixing box 4, a mounting box 6 is fixedly connected to the bottom of the fixing box 4, an operation instruction component 7 is arranged inside the mounting box 6, and a prompt component 8 is arranged on the front of the mounting box 6. More specifically, the fixing box 4 can be installed on the surface of the leakage circuit breaker body 1 through the locking component 5, and the circuit can be monitored through the leakage circuit breaker body 1. When the leakage circuit breaker body 1 detects leakage, the circuit is automatically cut off and the toggle switch 2 is tripped. At this time, the prompt component 8 runs automatically to provide sound and light prompts, so that the power personnel can find the disconnected leakage circuit breaker body 1 conveniently. At the same time, the operation instruction component 7 extends from the inside of the mounting box 6 to provide operation prompts for the power personnel.

[0026] like Figure 1 , Figure 2 As shown, the locking assembly 5 includes a bidirectional screw rod 501, and the bidirectional screw rod 501 is rotatably connected to the fixing box 4, the right end of the bidirectional screw rod 501 is fixedly connected to the first knob 502, the surface of the bidirectional screw rod 501 is threadedly connected to the bent rod 503, the top surface of the fixing box 4 is provided with a sliding groove 504, and the inner wall of the sliding groove 504 is slidably connected to the surface of the bent rod 503, and the surface of the bent rod 503 is fixedly connected to a positioning plug 505, and the side of the leakage circuit breaker body 1 is provided with a concave hole adapted to the positioning plug 505, and the inner wall of the concave hole is movably connected to the end of the positioning plug 505. It should be noted that by rotating the first knob 502, the bidirectional screw rod 501 is driven to rotate, and the bent rod 503 is driven to slide along the inner wall of the sliding groove 504 under the action of the thread, thereby driving the positioning plug 505 to move, so that the positioning plug 505 is inserted into the inner wall of the concave hole on the surface of the leakage circuit breaker body 1, and the fixing box 4 can be effectively limited.

[0027] like Figure 3 , Figure 4As shown, the operation instruction assembly 7 includes a rotating shaft 701, and the rotating shaft 701 is rotatably connected to the installation box 6, the right end of the rotating shaft 701 is fixedly connected to the second knob 702, a plastic paper tape 703 for recording maintenance and operation instruction information is wound on the surface of the rotating shaft 701, and one end of the plastic paper tape 703 is fixedly connected to the surface of the rotating shaft 701, and the free end of the plastic paper tape 703 is fixedly connected to a counterweight bar 704, an opening 706 is opened through the front side of the bottom of the installation box 6, a magnet strip 705 is fixedly connected to the bottom of the inner wall of the installation box 6, and the magnet strip 705 is electrically connected to the leakage circuit breaker body 1, and the magnet strip 705 is magnetically connected to the counterweight bar 704, and a blocking strip 707 is fixedly connected to the front side of the inner wall of the installation box 6. More specifically, when the leakage circuit breaker When the device body 1 trips, the magnet strip 705 loses power and loses its magnetic force, and will no longer attract the counterweight strip 704. Under the action of gravity, the counterweight strip 704 will fall and pull the free end of the plastic paper tape 703 down, so that the plastic paper tape 703 passes through the inside of the opening 706. The text content recorded on the surface of the plastic paper tape 703 facilitates the power personnel to carry out maintenance. When the maintenance is completed, the second knob 702 can be turned to drive the rotating shaft 701 to rotate, thereby winding the plastic paper tape 703, so that the counterweight strip 704 returns to the inside of the opening 706, and the magnet strip 705 is powered on again to attract the counterweight strip 704. By setting a baffle 707, the counterweight strip 704 is blocked to avoid excessive winding of the plastic paper tape 703.

[0028] like Figure 1 , Figure 3 As shown, the prompt component 8 includes an LED light bar 801, and the LED light bar 801 is fixedly installed on the front of the installation box 6.

At the same time, the LED light bar 801 can illuminate the nearby area to facilitate the inspection of the power personnel.

[0029] like Figure 1 As shown, a lithium battery is arranged at the bottom of the installation box 6, which is not shown in the figure, and the lithium battery is electrically connected to the LED light bar 801 and the buzzer 802.

[0030] like Figure 2 As shown, there are two groups of bent rods 503 and positioning blocks 505, and the two groups of bent rods 503 and positioning blocks 505 are symmetrically distributed with respect to the vertical center line of the front side of the leakage circuit breaker body 1. It should be noted that by symmetrically arranging the two groups of bent rods 503 and positioning blocks 505, the fixed box 4 is balanced and stably limited.

[0031] To sum up: the utility model can install the fixing box 4 on the surface of the leakage circuit breaker body 1 through the locking component 5, and the circuit can be monitored through the leakage circuit breaker body 1. When the leakage circuit breaker body 1 detects leakage, it automatically cuts off the circuit and trips the toggle switch 2. At this time, the prompt component 8 runs automatically and gives sound and light prompts, which is convenient for power personnel to find the broken leakage circuit breaker body 1. At the same time, the operation instruction component 7 extends from the inside of the installation box 6 to provide operation prompts for the power personnel.
