[0034] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown in the figure, an embodiment of this utility model provides a circuit breaker that is easy to install, comprising:

[0036] Wall 1;

[0037] Circuit breaker 2: The rear surface of circuit breaker 2 is in close contact with the interior of wall 1;

[0039] Fixed housing 310: The outer surface of the fixed housing 310 is fixedly connected to the upper surface of the circuit breaker 2;

[0040] Fixing groove 320: There are four fixing grooves 320, and all four fixing grooves 320 are opened inside the wall 1;

[0041] Fixing member 330: There are two fixing members 330. Both ends of the two fixing members 330 are in contact with the inner wall of the fixing groove 320. The outer surface of the fixing member 330 extends through the left and right sides of the fixing shell 310.

[0042] Springback assembly 340: The springback assembly 340 is disposed between the fasteners 330;

[0043] Push component 350: Push component 350 is disposed on the upper surface of the fixing member 330.

[0044] refer to Figure 3 As shown, the springback assembly 340 includes:

[0045] Fixing plate 341: The lower surface of fixing plate 341 is fixedly connected to the inner wall of fixing shell 310;

[0046] Sliding rod 342: The outer surface of the sliding rod 342 is fixedly connected to the inside of the fixing plate 341. Both ends of the sliding rod 342 are fixedly connected to the inner wall of the fixing shell 310. The outer surface of the sliding rod 342 is slidably connected to the inside of the fixing member 330.

[0047] Telescopic spring 343: Two telescopic springs 343 are provided. The two telescopic springs 343 are sleeved on the outer surface of the sliding rod 342. The opposite ends of the telescopic springs 343 are fixedly connected to the two sides of the fixing plate 341, and the opposite side of the telescopic springs 343 is fixedly connected to the opposite side of the fixing member 330.

[0048] Using the above method: the fixing member 330 moves along the outer surface of the sliding rod 342 to the opposite side, the fixing member 330 compresses the telescopic spring 343, causing the telescopic spring 343 to generate elastic force until the fixing member 330 is completely inserted into the fixing shell 310, then the circuit breaker 2 can be placed inside the wall 1. Then, the telescopic spring 343 releases its elastic force, pushing the fixing member 330 back until both ends of the fixing member 330 enter the fixing groove 320, thus achieving rapid installation of the circuit breaker 2.

[0049] refer to Figure 4 As shown, the actuating component 350 includes:

[0050] Push rod 351: There are two push rods 351, and the lower surfaces of the two push rods 351 are rotatably connected to the upper surface of the fixing member 330 through a rotating shaft;

[0051] Push block 352: The upper surface of push block 352 is rotatably connected to the lower surface of push rod 351 via a rotating shaft.

[0052] Using the above solution: In order to move the fixing member 330 to the opposite side, the pushing block 352 is moved forward. The pushing block 352 can drive the upper surface pushing rod 351 to move together and cause the pushing rod 351 to pull the fixing member 330 to the opposite side.

[0053] refer to Figure 4 As shown, a sliding rail 4 is provided on the lower surface of the push block 352. The upper surface of the sliding rail 4 is slidably connected to the lower surface of the push block 352, and the lower surface of the sliding rail 4 is fixedly connected to the inner wall of the fixed shell 310.

[0054] Using the above scheme, the sliding rail 4 mainly serves to provide a movement path for the push block 352.

[0055] refer to Figure 4 As shown, a rotating component 5 is provided on the upper surface of the pushing block 352. The rotating component 5 includes:

[0056] First rotating rod 501: The lower surface of the first rotating rod 501 is rotatably connected to the upper surface of the push block 352 via a rotating shaft;

[0057] Second rotating rod 502: The lower surface of the second rotating rod 502 is rotatably connected to the upper surface of the second rotating rod 502 via a rotating shaft.

[0058] Using the above scheme: In order to move the push block 352 forward, the second rotating rod 502 is rotated, and one end of the second rotating rod 502 can pull the first rotating rod 501 forward.

[0059] refer to Figure 4 As shown, a driving member 6 is provided on the upper surface of the second rotating rod 502. The lower end face of the driving member 6 is fixedly connected to the upper surface of the second rotating rod 502, and the driving member 6 passes through the upper surface of the fixed shell 310.

[0060] Using the above scheme: the driving component 6 mainly serves to drive the second rotating rod 502.

[0061] The working principle of this utility model:

[0062] In use, by rotating the drive component 6, the drive component 6 can drive the second rotating rod 502 to rotate. One end of the second rotating rod 502 can pull the first rotating rod 501 forward. The first rotating rod 501 can pull the push block 352 forward along the sliding rail 4. The push block 352 can drive the upper surface push rod 351 to move together and cause the push rod 351 to pull the fixing component 330 to move along the outer surface of the sliding rod 342 to the opposite side. The fixing component 330 compresses the telescopic spring 343, causing the telescopic spring 343 to generate elastic force until the fixing component 330 is completely inserted into the fixing shell 310. Then, the circuit breaker 2 can be placed inside the wall 1. Then, stop rotating the drive component 6, so that the telescopic spring 343 releases its elastic force and pushes the fixing component 330 back until both ends of the fixing component 330 enter the fixing groove 320, completing the quick installation of the circuit breaker 2.

[0063] In summary, this easy-to-install circuit breaker solves the problem of cumbersome installation by using a wall 1, circuit breaker 2, fixing mechanism 3, sliding rail 4, rotating assembly 5, and driving component 6. If the bolts are accidentally lost during installation, the stability of the circuit breaker after installation will be greatly reduced.
