Technical Field

[0001] The utility model relates to the technical field of a pull-cord switch seat, in particular to a pull-cord switch seat which is easy to install. Background Art

[0002] The working principle of the belt conveyor pull rope switch is to install a pull rope switch at a key position of the belt conveyor. When the operator finds an emergency, he can pull the pull rope to trigger the switch, causing the belt conveyor to stop running immediately. This design enables a quick response in an emergency to ensure the safety of personnel and equipment.

[0003] In the prior art, a Chinese patent document with authorization publication number CN219677115U describes a two-way pull-cord switch that is easy to install. By rotating a rotating wheel, the patent allows two push blocks threaded on two screws to push two stop blocks to move in opposite directions, so that the stop blocks are inserted into the stop grooves provided on the mounting blocks, thereby completing the final fixation between the fixed base and the rack base.
