[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 A fixed electrical safety sign for a small standard circuit breaker includes a circuit breaker body 1 and a sign body 11 mounted on the circuit breaker body 1. A warning sign 12 is fixedly installed on the upper end of the sign body 11, and a clamping component 2 fixed to the circuit breaker body 1 is provided at the lower end of the sign body 11. The clamping component 2 can fix the sign body 11 on circuit breaker bodies 1 of different sizes, making it widely applicable. A displacement component 3 for limiting the closing of the switch is provided at the lower end of the sign body 11. An adjustment component 4 for limiting the closing of switches of different widths is provided on the displacement component 3. The adjustment component 4 can fill the switch slots of different widths to prevent the switch from being closed by someone else during operation, thus preventing electric shock to the electrician.

[0021] The clamping assembly 2 includes four first sliding grooves 21 formed at the lower end of the sign body 11. Each of the four first sliding grooves 21 is slidably mounted with a clamping plate 22. A first spring 23 is provided between the clamping plate 22 and the first sliding groove 21. The shape of the first sliding groove 21 will not cause the first spring 23 to displace out of the first sliding groove 21. The first spring 23 has a large elastic force, which can drive the clamping plate 22 to move towards the center, thereby fixing the sign body 11 on the circuit breaker body 1. A rubber plate 24 is fixedly installed on the side wall of the clamping plate 22. The rubber plate 24 has several grooves 25. The rubber plate 24 is made of rubber and has flexibility and large adsorption capacity, which can prevent the circuit breaker body 1 from being crushed. The several grooves 25 can increase the friction with the circuit breaker body 1, preventing the sign body 11 from falling off and thus failing to play a warning role. A connecting plate 26 is fixedly installed on the side wall of two of the clamping plates 22. A connecting rod 27 is fixedly installed on the connecting plate 26.

[0022] The displacement assembly 3 includes a fixing plate 31 fixedly installed at the lower end of the sign body 11. A first chamber 32 is provided on the fixing plate 31. Second sliding grooves 33 are provided at both ends of the first chamber 32. A displacement plate 34 is slidably installed on the two second sliding grooves 33. A second spring 35 is provided between the displacement plate 34 and the first chamber 32. The function of the second spring 35 is to allow the displacement plate 34 to slide outward, thereby causing the displacement plate 34 to lock the switch in the closed position and prevent the switch from closing. An alarm button 36 is fixedly installed on the side wall of the fixing plate 31. When the alarm button 36 is pressed by the switch, an alarm will be triggered, thereby notifying the electrician to stop the work in time.

[0023] The alarm button 36 can be pressed by the closed switch. When the switch is closed, it will press the alarm button 36, thus emitting an alarm sound to remind the electrician.

[0024] In this embodiment: First, drag the two connecting rods 27, causing the connecting rods 27 to move the connecting plate 26, thereby causing the four clamping plates 22 to stretch the four first springs 23 and slide outward on the first slide groove 21. Then, place the sign body 11 on the circuit breaker body 1. At this time, release the two connecting rods 27. Under the action of the first springs 23, the four clamping plates 22 move towards the side wall of the circuit breaker body 1, thereby causing the rubber plate 24 to contact the circuit breaker body 1. The friction between the rubber plate 24 and the circuit breaker body 1 is increased by the several grooves 25, preventing friction with the circuit breaker body 1. When the sign body 11 falls off, it is adjusted during the fixing process so that the displacement plate 34 can align with the position of the switch slot. At this time, the displacement plate 34 moves downward under the action of the second spring 35, so that the displacement plate 34 is stuck in the position of the switch slot, thereby preventing the switch from accidentally closing, which may cause electric shock to the operator. When the switch moves in the closing direction, the switch just contacts the alarm button 36, thereby triggering an alarm to notify the operator and reminding the operator to put down their work in time to avoid electric shock.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The adjustment assembly 4 includes two second chambers 41 opened on both sides of the displacement plate 34. Two third slide grooves 42 are opened on both sides of the two second chambers 41. A trapezoidal block 43 is slidably installed on the four third slide grooves 42. A third spring 44 is provided between the trapezoidal block 43 and the second chamber 41. The third spring 44 can make the trapezoidal block 43 move outward, thereby filling the knife slots of different widths and avoiding accidental closing.

[0026] The trapezoidal surface of the trapezoidal block 43 is at the upper end of the trapezoidal block 43, which makes it easier for the trapezoidal block 43 and the displacement plate 34 to retract into the first chamber 32.

[0027] In this embodiment: For circuit breaker knife slots of different widths, the trapezoidal block 43 can be squeezed to make the trapezoidal block 43 squeeze the third spring 44 to slide on the second chamber 41. The trapezoidal block 43 can be adjusted by the third spring 44, which can limit the circuit breaker knife slots of different widths and increase the applicability.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
