Description

TECHNICAL FIELD

[0001] The utility model relates to a switching-on and switching-off technology field more specifically, it relates to a novel switching-on and switching-off structure. BACKGROUND

[0002] The measurement switch is also known as a measurement switch or a detection switch, which is an electrical element for controlling and monitoring specific parameters in a circuit. It is usually used to trigger action or signal when a set threshold is reached, and is widely used in industrial automation, process control, safety systems and other fields. The existing measurement switch, such as the existing patent CN202122860235.6, is mentioned in the specification

[0017] paragraph: the tripping mechanism adopts an energy storage type structure design, which can ensure that the tripping mechanism has a larger tripping force, thereby ensuring the action sensitivity of the tripping mechanism. When closing, the lever of the operating mechanism can push the top rod to act, and the top rod can compress the energy storage spring, thereby realizing the energy storage of the rack rod. When the line is abnormal, the coil is energized and the iron core is driven to act, the moving iron core drives the crank arm to act, the crank arm is unlocked with the top rod, and the top rod pushes the traction rod to act, thereby realizing the tripping and opening of the intelligent measurement switch, which can protect the line. However, the existing switching-on and switching-off structure is relatively complex, therefore, how to optimize the switching-on and switching-off structure is the technical problem to be solved by the present application. CONTENT OF THE UTILITY MODEL

[0003] In view of the deficiencies in the prior art, the utility model provides a novel switching-on and switching-off structure, which realizes the activity connection of multiple hooks and multiple components through a linkage rod, thereby optimizing the structure.

[0004] The technical scheme of the utility model is as follows:

[0005] A novel switching-on and switching-off structure, which comprises a lever and a tripping device arranged in a measurement switch housing.

[0006] The tripping device comprises a base, a reset spring assembly, a linkage rod and a reset piece arranged on the base, the linkage rod and the base are slidingly connected, the linkage rod extends out a first hook to one side of the lever, a second hook to one side of the reset spring assembly, and a third hook to one side of the reset piece.

[0007] When the lever is closed, the linkage rod is driven to slide through the first hook, the reset spring assembly is compressed through the second hook by the linkage rod, and the reset piece hooks the linkage rod through the third hook. When the reset spring assembly abuts against the reset piece, the reset piece and the third hook are unhooked, so that the lever is opened.

[0008] In summary, the technical scheme has the following beneficial effects: the opening and closing structure is used in the measuring switch, the lever controls the closing of the measuring switch, the trip device is movably connected with the lever, the reset spring assembly and the reset member through a single linkage rod, and the closing and opening of the measuring switch are realized. When the line is abnormal after the closing, the reset spring assembly acts, drives the linkage rod and the reset member to separate, and makes the reset spring assembly resist the second pull hook to make the linkage rod slide and reset, the first pull hook drives the lever to open, so that the trip opening of the measuring switch is realized, and the line is protected.
