Description

Technical Field

[0001] The utility model relates to the technical field of power distribution devices, in particular to an externally mounted mobile power distribution device on a construction site. Background Art

[0002] A power distribution device is an electrical device used to distribute electrical energy. It usually includes components such as circuit breakers, disconnectors, load switches, fuses, relays, etc. The function of the power distribution device is to distribute the electrical energy of the power supply to various electrical devices, while protecting and controlling the circuit.

[0003] Power distribution devices are indispensable during construction work at a construction site. As a carrier for equipment, lighting and temporary power supply, they play a very important role. However, workers move back and forth at a construction site and carry equipment back and forth, so sometimes they need to move the power distribution devices together to ensure power supply. However, most existing power distribution devices connect the wires to the switches inside the power distribution devices and then use them directly. Workers are likely to kick or pull the wires, resulting in poor contact of the wires or even a short circuit. In addition, the wiring of temporary electricity is disorganized, and the distribution cabinets do not have a clear classification structure, making them inconvenient to use. Utility Model Content

[0009] Preferably, a linear limit groove is provided on the surface of the fixed plate, and an arc-shaped interference groove is provided on the surface of the rotating plate. Since the fixed plate is fixedly connected to the inner wall of the threaded fixing column, the linear limit groove will not rotate, and the linear limit groove and the positioning rod will limit the slider.

[0010] Preferably, a toggle rod is fixedly connected to the side of the rotating plate, and the position of the toggle rod is aligned with the position of the arc-shaped through groove. After the connecting cover is about to be completely tightened, the resistance rod will be inserted into the arc-shaped through groove, and the rotation of the connecting cover will drive the resistance rod to rotate a certain distance along the arc-shaped through groove.

[0013] Preferably, there are two groups of sliders, and the two groups of sliders are respectively located in the linear limit grooves opened on the surfaces of the two groups of fixed plates, and a sliding rod is fixedly connected between the two groups of sliders. After the interference rod and the toggle rod interfere with each other, the toggle rod will be pushed to rotate around the center of the rotating plate, and the toggle rod will drive the rotating plate to rotate together. The sliding rod passes through the arc-shaped interference groove and is slidably connected.

[0014] Compared with the prior art, the utility model provides an external mobile power distribution device for construction sites, which has the following beneficial effects:

[0015] 1. This external mobile distribution device for construction sites will push the toggle rod to rotate with the center of the rotating plate as the axis after the contact rod and the toggle rod contact each other, and the toggle rod will drive the rotating plate to rotate together, so that the arc-shaped contact groove on the surface of the rotating plate pushes the slide rod to slide along the arc-shaped contact groove, but because the fixed plate is fixedly connected to the inner wall of the threaded fixed column, the linear limit groove will not rotate, and the linear limit groove and the positioning rod will limit the slider, so that the slider can only slide along the inner side of the linear limit groove under the sliding of the slide rod and compress the spring, and when the slider slides, it will push the push rod to fix the clamping block to the wires of the distribution cabinet, so as to avoid the workers at the construction site accidentally pulling the equipment lines, causing the lines connected to the distribution switch in the distribution cabinet to loosen and cause a short circuit.

[0026] The threaded fixing column 21 passes through the rear side of the power distribution cabinet 1. When the power distribution device is used, the power line is first connected to the power distribution switch 5 in the power distribution cabinet 1, and then the line of the device is passed through the connection cover 22 and the threaded fixing column 21 in the connection part 2 and connected to the power distribution switch 5. At this time, the power distribution switch 5 is closed to ensure the safety of the installation. The threaded fixing column 21 is fixedly connected to the power distribution cabinet 1, the threaded fixing column 21 passes through the connection cover 22, and the threaded fixing column 21 is threadedly connected to the connection cover 22. The inner side of the connection cover 22 is fixedly connected with a resistance rod 23, and the fixing plate 24 passes through the threaded fixing column 21, and the fixing plate 24 is fixedly connected to the inner side of the threaded fixing column 21. The surface of the fixing plate 24 is provided with an arc-shaped through groove 25. There are two groups of fixing plates 24, and the two groups of fixing plates 24 are respectively fixedly connected to the inner side of the threaded fixing column 21, and a rotating plate 26 is rotatably connected between the two groups of fixing plates 24. A linear limiting groove 27 is provided on the surface of the fixed plate 24, and an arc-shaped abutting groove 28 is provided on the surface of the rotating plate 26. Since the fixed plate 24 is fixedly connected to the inner wall of the threaded fixing column 21, the linear limiting groove 27 will not rotate, and the linear limiting groove 27 and the positioning rod 210 will limit the slider 211, so that the slider 211 can only slide along the inner side of the linear limiting groove 27 under the sliding of the slide rod 215 and compress the spring 214. A toggle rod 29 is fixedly connected to the side of the rotating plate 26, and the position of the toggle rod 29 is aligned with the position of the arc-shaped through groove 25. The connecting cover 22 is aligned with the threaded fixing column 21, inserted and rotated, so that the connecting cover 22 is gradually threadedly connected with the threaded fixing column 21. After the connecting cover 22 is about to be completely tightened, the abutting rod 23 will be inserted into the arc-shaped through groove 25, and the connecting cover 22 will drive the abutting rod 23 to rotate a certain distance along the arc-shaped through groove 25 when the connecting cover 22 rotates. A positioning rod 210 is fixedly connected to the inner side of the linear limit groove 27, and the positioning rod 210 penetrates and is slidably connected to a slider 211. A push rod 212 is fixedly connected to the surface of the slider 211, and a clamping block 213 is fixedly connected to the end of the push rod 212 close to the axis of the fixed plate 24. When the slider 211 slides, it pushes the push rod 212 to fix the clamping block 213 to the wires of the power distribution cabinet 1, so as to prevent the workers at the construction site from accidentally pulling the equipment line, causing the line connected to the distribution switch 5 in the power distribution cabinet 1 to loosen and cause a short circuit. A spring 214 is fixedly connected to the surface of the slider 211, and the end of the spring 214 away from the slider 211 is fixedly connected to the inner side of the linear limit groove 27. There are two groups of sliders 211, and the two groups of sliders 211 are respectively located in the linear limit grooves 27 opened on the surfaces of the two groups of fixed plates 24, and a sliding rod 215 is fixedly connected between the two groups of sliders 211. After the resistance rod 23 and the toggle rod 29 are in resistance, the toggle rod 29 will be pushed to rotate around the center of the rotating plate 26, and the toggle rod 29 will drive the rotating plate 26 to rotate together, causing the arc-shaped resistance groove 28 opened on the surface of the rotating plate 26 to push the sliding rod 215 to slide along the arc-shaped resistance groove 28, and the sliding rod 215 passes through the arc-shaped resistance groove 28 and is slidably connected.

[0027] Based on the above embodiment, when the power distribution device is used, the power cord is first connected to the power distribution switch 5 in the power distribution cabinet 1, and then the line of the device is passed through the connection cover 22 and the threaded fixing column 21 in the connection part 2 and connected to the power distribution switch 5.

After the connection cover 22 is about to be completely tightened, the resistance rod 23 will be inserted into the arc groove 25, and the rotation of the connection cover 22 will drive the resistance rod 23 to rotate a certain distance along the arc groove 25. After the resistance rod 23 conflicts with the toggle rod 29, it will push the toggle rod 29 to rotate with the center of the rotating plate 26 as the axis, and the toggle The rod 29 will drive the rotating plate 26 to rotate together, causing the arc-shaped contact groove 28 opened on the surface of the rotating plate 26 to push the sliding rod 215 to slide along the arc-shaped contact groove 28, but because the fixing plate 24 is fixedly connected to the inner wall of the threaded fixing column 21, the linear limit groove 27 will not rotate, and the linear limit groove 27 and the positioning rod 210 will limit the slider 211, so that the slider 211 can only slide along the inner side of the linear limit groove 27 under the sliding of the sliding rod 215 and compress the spring 214, and when the slider 211 slides, it will push the push rod 212 to fix the clamping block 213 to the wires of the distribution cabinet 1, so as to avoid the workers at the construction site accidentally pulling the equipment lines, causing the lines connected to the distribution switch 5 in the distribution cabinet 1 to loosen and cause a short circuit.
