Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a switch device used for starting a generator. Background Art

[0002] The switch for starting the generator is usually an electromagnetic switch, which uses electromagnetic suction to drive the fork to start. During the starting process, the current flows through the magnetic coil through a specific circuit path, magnetizing the iron core and generating suction, thereby controlling the closing of the moving contact and the static contact. When the moving contact and the static contact are closed, the motor starts to rotate and the generator enters the starting state. Once the generator starts, the circuit in the switch device will be adjusted accordingly to ensure that the motor can run stably after starting.

[0003] When the switch device for starting the generator is used, the contactor is easily worn or damaged after long-term and repeated use, and needs to be disassembled and replaced. In the existing switch device, it is troublesome to disassemble and assemble the protective shell. At the same time, the installation and disassembly steps of the contactor are extremely cumbersome, and it is difficult to quickly replace and disassemble it. Utility Model Content

Through this arrangement, the fixed rod 98 can be embedded in 99 for fixation.

[0025] Here’s how it works:

[0026] First, when in use, the relay 2 is started, so that the relay 2 generates magnetic force to push the armature 3 to move, and when the armature moves 3, the movable contactor 7 is pushed to move, and when the movable contactor 7 moves, it contacts with the stationary contactor 6, and the electric device 5 is rotated by connecting the wires, and when the electric device 5 rotates, the small gear on the electric device 5 is driven to rotate, so that the generator starts to work;

[0027] Second, after being used many times, the movable contactor 7 is worn and needs to be replaced. The movable block 96 is pushed to move along the light rod 95. When the movable block 96 moves, the fixed rod 98 is driven to move so that the fixed rod 98 moves out of the slot 99. Then, the opening and closing plate 92 is pulled to turn over the opening and closing plate 92 to cancel the blocking of the opening and closing slot 91.

[0028] Third, after the opening and closing plate 92 is opened, the pull block 87 is pulled upward, and the pull block 87 drives the upper fixed block 83 to move, and the upper fixed block 83 is moved out of the fixed groove 82, and then the movable contactor 7 is pressed, so that the movable contactor 7 drives the lower fixed block 81 to move downward, and the lower fixed block 81 is moved out of the fixed groove 82, and the movable contactor 7 can be removed for replacement;

[0029] Fourth, put the new movable contactor 7 into the housing 1, then pull the pull block 87 upwards, the pull block 87 drives the upper fixed block 83 to move, the upper fixed block 83 squeezes the spring 1 86 when moving, then the lower fixed block 81 is embedded in the fixed groove 82, then release the pull block 87, the spring 1 86 loses its force and pushes the upper fixed block 83 to embed it in the fixed groove 82, thus completing the fixation of the new movable contactor 7;

[0030] Fifth, push the movable block 96 to move along the light rod 95. When the movable block 96 moves, it drives the fixed rod 98 to move. When the movable block 96 moves, it squeezes the spring 2 97. Then, rotate the opening and closing plate 92 to make the opening and closing plate 92 move into the opening and closing groove 91. Release the movable block 96. After the spring 2 97 loses its force, it pushes the movable block 96 to move. The movable block 96 pushes the fixed rod 98 to embed into the card slot 99, so that the opening and closing plate 92 can be fixed. The replacement action is completed and it can be put into use.
