Description

TECHNICAL FIELD

[0001] The utility model relates to power switch technical field, concretely is a kind of interlock structure of power switch. BACKGROUND

[0002] The main function of power switch is to turn on or off the power in the circuit, thereby controlling the operation and stop of electrical equipment. By operating the power switch, the start, shutdown, restart and other operations of the equipment can be realized. The working principle of power switch is based on the on-off principle of circuit. When the switch is in the on state, the power in the circuit forms a path with the load, and the current can flow through the load; when the switch is in the off state, the connection between the power in the circuit and the load is cut off, and the current cannot flow through the load. In order to prevent power short circuit and misoperation, interlock structure is needed for power switch.

[0003] The interlock structure of common power switch is usually composed of switch body, interlock mechanism, reset mechanism and indicating device. The switch body includes main switch and interlock switch, which control different power or circuit respectively. The interlock mechanism is the core part to realize interlocking function, which can be mechanical interlock mechanism or electrical interlock mechanism. The reset mechanism is used to restore the switch to the initial state after switching, so as to perform the next switching. The indicating device is used to display the state of the current switch (such as on or off), so that the operator can understand the running condition of the system.

[0004] The interlock structure of traditional power switch usually uses lock pin, gear or other mechanical device to realize interlocking function. When one switch is opened, the related mechanical device will lock the lock pin or gear of the other switch through linkage system, so as to prevent them from being opened. Due to the relatively complex design, installation and debugging of mechanical interlocking device, the structural complexity is increased. To solve the above problems, part of the interlock structure of power switch adds a rotating rod at the center of the switch, and the two ends of the rotating rod are connected with two groups of switches respectively. When one group of switch is opened, the other group of switch is closed through the rotating rod, so as to realize the interlocking operation of power switch, and the interlocking structure is simple and convenient to use. However, this method is not convenient for maintaining the stability of power switch during interlocking, and is not convenient for use. Therefore, an interlock structure of power switch is proposed.
