[0026] A modular combined vacuum circuit breaker comprises a vacuum circuit breaker body 1 and a mounting seat 2 with modular design, wherein a fixing seat 3 is fixedly connected to the bottom of the vacuum circuit breaker body 1 and located inside the mounting seat 2, and a mounting through hole 4 and a fixing screw hole 5 are respectively provided at the center of both sides of the fixing seat 3, the mounting through hole 4 and the fixing screw hole 5 are connected, and the radius of the mounting through hole 4 is greater than the radius of the fixing screw hole 5.

[0027] A fixed round rod 6 is arranged in the mounting through hole 4, and a rotating control rod 7 is fixedly connected to one end of the fixed round rod 6 and located outside the fixing seat 3, and a fixed screw 8 is fixedly connected to one end of the fixed round rod 6 away from the rotating control rod 7. The fixed screw 8 and the fixed screw hole 5 are threadedly connected, and the fixed screw 8 and the rotating control rod 7 both pass through the mounting seat 2 and extend to the outside of the mounting seat 2, so as to fix the fixing seat 3 to the mounting seat 2.

[0028] like Figure 1 , Figure 3 and Figure 5The vacuum circuit breaker body 1 is a vacuum circuit breaker with modular design in the prior art, which has the advantages of simple structure, easy assembly and maintenance, and will not be described in detail here. An opening is provided at the top of the mounting seat 2, and the fixing seat 3 is located in the opening at the top of the mounting seat 2. The centers of the mounting through hole 4 and the fixing screw hole 5 are located in the same horizontal direction, and openings are provided on both sides of the mounting seat 2 to facilitate the passage of the fixing screw 8 and the rotating control rod 7.

[0029] Positioning protrusions 9 are fixedly connected to both sides of the inner wall of the mounting seat 2 , and positioning grooves 10 used in conjunction with the positioning protrusions 9 are provided on both sides of the fixing seat 3 .

[0030] like Figure 1 , Figure 3 and Figure 4 When the fixing seat 3 is located in the mounting seat 2 , the positioning protrusion 9 can be relatively inserted into the interior of the positioning groove 10 .

[0031] An adjustment slot 11 is provided at the connection between the mounting through hole 4 and the fixing screw hole 5 , a tension spring 12 is fixedly connected to the inner wall of the adjustment slot 11 , one end of the tension spring 12 is fixedly connected to a movable bracket 13 , and both ends of the movable bracket 13 are fixedly connected to clamping rods 14 .

[0032] like Figure 4 and Figure 5 There is an opening at the center of the movable bracket 13, the radius of the opening is larger than the radius of the fixing screw hole 5, but smaller than the radius of the mounting through hole 4, so that the fixing screw 8 can pass through the movable bracket 13, while the fixing round rod 6 cannot pass through the movable bracket 13.

[0033] The positioning protrusion 9 is provided with a clamping hole 901 , and one end of the clamping rod 14 passes through the clamping hole 901 and extends to the outside of the positioning protrusion 9 .

[0034] like Figure 4 The inner wall of the positioning groove 10 has an opening so that the clamping rod 14 can extend from the inside of the fixing seat 3.

[0035] A positioning notch 15 is formed at the bottom of the mounting seat 2 , and a positioning protrusion 16 that cooperates with the positioning notch 15 is fixedly connected to the bottom of the fixing seat 3 .

[0036] like Figure 1 and Figure 2 The positioning protrusion 16 is just clamped in the positioning groove 15, thereby improving the stability of the connection between the mounting seat 2 and the fixing seat 3.

[0037] A connecting sleeve 17 is fixedly connected to one side of the mounting seat 2. The connecting sleeve 17 is sleeved on the outer surface of the fixing screw 8. A fixing pin 18 is arranged on the connecting sleeve 17. The bottom of the fixing pin 18 passes through the connecting sleeve 17 and the fixing screw 8 in sequence and extends to the outside of the connecting sleeve 17.

[0038] like Figure 1 and Figure 6 The fixing pin 18 can pass through the fixing screw 8 and be clamped together with the connecting sleeve 17 to prevent the fixing screw 8 from loosening.

[0039] The working principle of a modular combined vacuum circuit breaker provided by the utility model is as follows:

[0040] When the fixing seat 3 is inserted into the mounting seat 2, the fixing screw 8 can be extended into the fixing seat 3 from the side where the mounting through hole 4 is located, and the rotation control rod 7 is rotated so that the fixing screw 8 and the fixing screw hole 5 are threadedly connected together;

[0041] The fixed round rod 6 moves together with the fixed screw rod 8. At this time, one end of the fixed round rod 6 will squeeze the movable bracket 13, and the movable bracket 13 drives the clamping rod 14 to move. The clamping rod 14 passes through the positioning protrusion 9 to clamp the positioning protrusion 9 and the fixing seat 3 together. At this time, the positioning protrusion 9 will form a clamping between the mounting seat 2 and the fixing seat 3, and the two ends of the fixing seat 3 will also form a clamping between the fixing seat 3 and the mounting seat 2;

[0042] After rotating the rotation control rod 7 to separate the fixing screw 8 and the fixing screw hole 5, the fixing screw 8 and the fixing round rod 6 can be pulled out from the end where the fixing round rod 6 is located, and then the tension spring 12 will shrink and pull the movable bracket 13, and the movable bracket 13 will drive the clamping rod 14 and the positioning protrusion 9 to separate, and at this time the fixing seat 3 and the mounting seat 2 can be separated.

[0043] Compared with the related art, the modular combined vacuum circuit breaker provided by the utility model has the following beneficial effects:

[0044] The utility model realizes that the fixing screw 8 is threadedly connected to the fixing screw hole 5, and the fixing round rod 6 is clamped into the mounting through hole 4. The fixing screw 8 and the rotating control rod 7 both penetrate the mounting seat 2, so as to clamp the mounting seat 2 and the fixing seat 3. At the same time, the fixing round rod 6 will push the movable bracket 13, so that the clamping rod 14 passes through the positioning protrusion 9, and clamps the positioning protrusion 9 and the fixing seat 3 together, so that the mounting seat 2 and the fixing seat 3 can be clamped and fixed from multiple points only by rotating the fixing round rod 6, or the mounting seat 2 and the fixing seat 3 can be disassembled, which is simple to operate and convenient for installation and disassembly between the vacuum circuit breaker body 1 and the mounting seat 2.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
