Description

Technical Field

[0001] The utility model relates to an emergency stop button accessory, in particular to an emergency stop button protective cover. Background Art

[0002] An "e-stop" button, short for "emergency stop button," is a protective measure used by quickly pressing it in an emergency. Inside factories, you'll find prominent red buttons on large and medium-sized machinery and appliances, labeled "Emergency Stop" in red font. These buttons, collectively known as emergency stop buttons, simply press downward to instantly stop the entire machine or release certain transmission components. To restart the machine, the button must be released. Simply rotate it approximately 45° clockwise and release it. The pressed portion will pop up, releasing the emergency stop button.

[0003] Existing emergency stop buttons typically consist of a contact module, a button base, and a button head. The button base is fixed to the contact module, and the button head is connected to the button base via a spring, used to press or release the contacts on the contact module. The button head is generally mushroom-shaped, with a smaller diameter support portion and a larger diameter cap portion.

[0004] Some emergency stop button covers have mounting holes sized to match the diameter of the support. Installing the cover requires first separating the button head cap from the support, then fitting the cover over the support, and finally, the button head cap. Some emergency stop button caps are not removable, requiring the entire button base to be removed from the contact module before installing the cover. This makes installing the cover a cumbersome process and can easily cause the connecting wires to become detached, short-circuiting, and damaging the emergency stop button. Utility Model Content
