[0024] Example

[0025] Refer to attached figure Figure 1 - Appendix Figure 5 This utility model provides an easily disassembled indoor circuit breaker, including a fixing structure 1, a circuit breaker assembly 2, and an installation structure 3. The circuit breaker assembly 2 is installed on the fixing structure 1 via the installation structure 3. The fixing structure 1 includes an installation plate 101, with installation holes 102 at the four corners of the installation plate 101. The circuit breaker assembly 2 includes a square frame 201 and a circuit breaker body 203. The square frame 201 is fixedly installed on the installation plate 101. Slide bars 202 are fixedly installed at the upper and lower ends of the inner wall of the square frame 201, respectively. The circuit breaker body 203 is disposed inside the square frame 201. Slide grooves 204 adapted to slide bars 202 are respectively opened at the upper and lower ends of the circuit breaker body 203. The slide grooves 204 and slide bars 202 have the same length and are slidably connected.

[0026] Mounting structure 3 includes a through hole 301, a fixing cylinder 302, a limiting hole 307, a screw 308, and an insertion hole 312. A pair of through holes 301 are provided and symmetrically opened on the side wall of the square frame 201. The fixing cylinder 302 is a cylindrical body closed at one end and open at the other. The open end of the fixing cylinder 302 is fixedly installed on the outer wall of the square frame 201, and the fixing cylinder 302 is aligned with the through hole 301. The inner diameter of the fixing cylinder 302 is the same as that of the through hole 301. The side of the fixing cylinder 302... A sliding rod 303 is provided on the wall. One end of the sliding rod 303 passes through the fixed cylinder 302 and extends to the outside of the fixed cylinder 302. A pin 304 is fixedly installed at one end of the sliding rod 303. The end of the pin 304 is hemispherical and extends into the through hole 301. The pin 304 is slidably connected to the inner wall of the fixed cylinder 302 and the through hole 301. A spring 305 is sleeved on the sliding rod 303. One end of the spring 305 is fixedly connected to the inner wall of the fixed cylinder 302, and the other end is fixedly connected to the pin 304. 4. Fixed connection: A disc 306 is fixedly installed on the end of the slide rod 303 away from the plug 304. Limiting holes 307 are respectively opened on both sides of the circuit breaker body 203. The limiting holes 307 and the plug 304 are adapted to each other. The outer circle of the limiting hole 307 is arc-shaped. By making the end of the plug 304 hemispherical and the outer circle of the limiting hole 307 arc-shaped, the plug 304 can be easily inserted into and disengaged from the limiting hole 307. The screw 308 rotates by rotating the seat. The circuit breaker body 203 is symmetrically installed on the top wall of the outer side of the square frame 201. A turntable 309 is fixedly installed at one end of the screw 308. A connecting rod 310 is threaded on the screw 308. Insert rods 311 are fixedly installed at both ends of the connecting rod 310. The insert rods 311 pass through the top wall of the square frame 201 and extend into the interior of the square frame 201. The insert rods 311 and the top wall of the square frame 201 are slidably connected. The insertion holes 312 are symmetrically opened on the top of the circuit breaker body 203 and are adapted to the insert rods 311.

[0027] During use, the mounting plate 101 is fixed through the mounting hole 102. The circuit breaker body 203 slides into the square frame 201 along the slide bar 202 inside the square frame 201 via the slide groove 204, and is inserted into the square frame 201. At this time, the circuit breaker body 203 will press the plug 304 and compress the spring 305. When the plug 304 and the limiting hole 307 are aligned, the plug 304 is locked into the limiting hole 307 under the action of the spring 305, thereby initially limiting the circuit breaker body 203. The turntable 309 is rotated, and the turntable 309 drives the screw 308 to rotate, thereby driving the connection The rod 310 moves, causing the insert rods 311 at both ends of the connecting rod 310 to be inserted into the insertion hole 312, achieving double fixation. When disassembling, the turntable 309 is rotated in the opposite direction to disengage the insert rods 311 from the insertion hole 312, and the circuit breaker body 203 is pulled. Because the end of the insert post 304 is hemispherical and the outer side of the limiting hole 307 is arc-shaped, the insert post 304 can easily disengage from the limiting hole 307. If there is jamming, the disc 306 is pulled to drive the sliding rod 303 to make the insert post 304 exit the limiting hole 307, and the circuit breaker body 203 can be pulled out along the sliding bar 202.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
