Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker protection, in particular to a circuit breaker waterproof box. Background Art

[0002] Circuit breakers are used to protect electrical appliances from damage or fire caused by excessive current. When the circuit breaker needs to be installed outdoors or in a humid environment, a waterproof box must be installed outside the circuit breaker to ensure stable and safe use of the circuit breaker.

[0003] Existing circuit breakers are usually installed with a base, which is usually composed of bolts and a supporting structure. The base is selected according to the size and model of the circuit breaker. The base provides a stable supporting structure to ensure the stable installation of the circuit breaker. It can effectively fix the circuit breaker to prevent it from loosening or shaking during operation. At the same time, by installing the base, the circuit breaker can be easily maintained and replaced. The base provides a reliable connection point, so that the circuit breaker can be easily disassembled and installed, reducing the difficulty of maintenance and replacement.

[0004] However, when used in some humid environments, most bases are only closed with snaps. If installed through the base, water may enter the circuit breaker. If water enters the circuit breaker, the current may be conducted through the water flow, increasing the risk of electric shock. This poses a threat to personnel safety and may cause electric shock accidents. At the same time, when water enters the circuit breaker, it may cause a short circuit or overload between electrical components. The presence of water may cause abnormal current flow, exceeding the rated capacity of the circuit breaker, causing equipment damage, overheating of wires, or fire. Therefore, a circuit breaker waterproof box is proposed to solve the above problems. Utility Model Content

[0034] Specifically, the opening and closing cover 2 is closed on the box body 1. At this time, the plug block 7 on the opening and closing cover 2 will be inserted into the slot 14 inside the box body 1. The worm 9 is driven to rotate by the handle 8. The rotation of the worm 9 drives the worm wheel 10 to rotate through the engagement with the worm wheel 10. The rotating rod 23 fixed on the worm wheel 10 rotates accordingly. The rotation of the rotating rod 23 will drive the transmission rods 11 on both sides to move. The transmission rods 11 on both sides pull the center of the clamping rods 13 on both sides to slide through the connecting rods 12. The clamping rods 13 will be inserted into the clamping groove 6 opened on the plug block 7, so that the opening and closing cover 2 is fixed on the box body 1. At the same time, the sealing gasket 17 between the box body 1 and the opening and closing cover 2 will be pressed to prevent moisture from entering, so as to protect the circuit breaker module 4 in the box body 1.

[0035] Reference Figure 1 and Figure 4 The box body 1 is provided with a mounting assembly, which includes a steel plate 16 and a breaker module 4. Both sides of the steel plate 16 are fixedly connected to the box body 1. One side of the breaker module 4 is slidably connected to the steel plate 16. The opening and closing cover 2 is fixedly connected to an acrylic plate 3. A rectangular array of mounting holes 15 is provided in the box body 1.

[0036] Specifically, when the acrylic plate 3 is used, the breaker module 4 can be installed inside the acrylic plate 3 through the steel plate 16, and then the opening and closing cover 2 is closed. At the same time, the acrylic plate 3 on the opening and closing cover 2 monitors the breaker module 4 fixed inside the box body 1.

[0037] Reference Figure 4 and Figure 5 A pressurized chamber 21 is provided on one side of the box body 1, a threaded rod 19 is threadedly connected to one side of the box body 1, a piston plate 20 is rotatably connected to the bottom of the threaded rod 19, and the outer wall of the piston plate 20 is slidably connected to the inside of the pressurized chamber 21, and air guide tubes 22 are fixedly connected to both sides of the box body 1, one end of the air guide tube 22 is fixedly connected to the inside of the pressurized chamber 21, an air bag 5 is fixedly connected to one side of the outer wall of the box body 1, and the other end of the air guide tube 22 is fixedly connected to the inside of the air bag 5, and a driving block 18 is fixedly connected to the top of the threaded rod 19, and the outer wall of the driving block 18 is rotatably connected to the inside of the box body 1;

[0038] Specifically, first, install the protective box body 1 on the wall and fix it in an appropriate position. The mounting hole 15 can be used to fix the box body 1 to ensure that the box body 1 is firmly connected to the wall. Next, drive the threaded rod 19 through the drive block 18. By rotating the threaded rod 19, it moves downward, which will push the piston plate 20 to slide inside the pressurized chamber 21. When the piston plate 20 slides, the gas in the pressurized chamber 21 will be pushed into the air duct 22 and then introduced into the airbag 5, causing the airbag 5 to begin to expand. As the airbag 5 expands, it will fill the gap between the protective box body 1 and the wall, ensuring a close connection between the two and effectively preventing moisture penetration.

[0039] Working principle: When the box body 1 is in use, the opening and closing cover 2 can be closed on the box body 1. At this time, the plug block 7 on the opening and closing cover 2 will be inserted into the slot 14 inside the box body 1, and then the handle 8 drives the worm 9 to rotate. The worm 9 can drive the box body 1 to rotate by meshing with the worm wheel 10, and at the same time, the rotating rod 23 fixed on the worm wheel 10 rotates accordingly, and the rotating rod 23 drives the transmission rods 11 on both sides to move, so that the transmission rods 11 on both sides pull the center of the clamping rods 13 on both sides to slide through the connecting rod 12, and the clamping rod 13 will be inserted into the clamping slot 6 provided on the plug block 7, so that the opening and closing The cover 2 is fixed on the box body 1, and the sealing gasket 17 between the box body 1 and the opening and closing cover 2 will be compressed to prevent water from entering the gap between the two. When the protective box is installed in the wall, the box body 1 can be fixed by the mounting hole 15, and then the threaded rod 19 is driven by the driving block 18. The threaded rod 19 will rotate downward, thereby pushing the piston plate 20 to slide inside the pressurizing chamber 21. The gas inside the pressurizing chamber 21 will be introduced into the airbag 5 through the air guide tube 22 to expand the airbag 5. The airbag 5 will fill the gap between the box body 1 and the wall to achieve waterproofing between the two.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
