Abstract
A new-type travel switch is provided, which comprises a main axle, a contact arm, a shell body and a fixing stand positioned on the main axle. The utility model is characterized in that: a rocker arm board contactor is connected solidly to the main axle; a resetting spring that can realize the double-diction resetting of the rocker arm board contactor is also positioned on the main axle; a contactor box is arranged at one side of the rocker arm board contactor. The utility model has the advantages of: big corner, small volume, light weight, excellent impact resistance, labor saving for installation, convenient adjustment of corner angle, excellent sealing performance and a pair of open and close contacts in the contact box of the switch.
Description
Technical field:
The utility model belongs to a kind of low-voltage electrical apparatus switch, particularly a kind of novel travel switch.
Technical background:
Be applied in the travel switch in the industry equipment mechanisms such as some metallurgy, mine, cement, electric power and chemical industry at present, have that volume is big, corner is less, a corner angle adjustment inconvenience, robust shortcoming and defect inadequately.
The utility model content
The purpose of this utility model provides a kind of novel travel switch, and corner is big, and volume is little, and is in light weight, shock-resistant, installs laborsavingly, and the corner angle adjustment is convenient.
The purpose of this utility model is achieved by the following technical solution: it comprises main shaft, is installed in contact arm, housing and holder on the main shaft, it is characterized in that: the rocker plate that on main shaft, is fixedly connected contact, being provided with simultaneously can be to the return spring of rocker plate contact two-way reset, at the side assembling contact box of rocker plate contact.
Above-mentioned contact arm is plugged on the main shaft by its circular socket holes, is provided with on the jack limit and cracks, and its side is screwed trip bolt.
The said fixing seat is horizontal base or vertical bearing.
The utility model has the advantages that: corner is big, and volume is little, and is in light weight, shock-resistant, installs laborsavingly, and the corner angle adjustment is convenient, good seal performance, and the contact box in the switch often have open, each is a pair of for normally-closed contact.
Operation principle: when external force acted on the contact arm of travel switch, contact arm rotated to an angle, and the rocker plate contact in the mechanism also rotates same angle, triggered the contact box action this moment and sent signal.Adjust the corner angle and only need unclamp trip bolt on the contact arm circular socket holes, contact arm and main shaft be activity circumferentially, adjust the corner angle again trip bolt get final product.
