Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a protective cover for a railway passenger car button. Background Technology

[0002] Currently, emergency equipment such as emergency communication buttons, emergency brake handles, and emergency door openers are installed in the passenger areas of railway passenger cars and other means of transportation. Such equipment is only allowed to be operated under certain special conditions. Under normal circumstances, such equipment cannot be operated or triggered. However, during vehicle operation, accidental triggering of the equipment due to factors such as accidental touching or contact by passengers may cause the vehicle to respond, resulting in operational risks.

[0003] Therefore, to meet practical needs, a protective cover for railway passenger car buttons is provided. Summary of the Invention

[0021] The inner diameter of the arc-shaped enclosure of the flip-top cover is larger than the outer diameter of the cylindrical base, but smaller than the outer diameter of the annular base.

[0022] Based on the above technical solution, the flip cover is hinged to the fixed base via a pivot.

[0023] Based on the above technical solution, the rotating shaft is disposed on the annular base and is symmetrically distributed with the buckle relative to the center of the annular base.

[0024] Based on the above technical solution, the flip cover is provided with a rotational force-applying protrusion;

[0025] The rotating shaft and the rotating force-applying protrusion are symmetrically distributed relative to the center of the flip cover.

[0026] Based on the above technical solution, the maximum flip angle of the flip cover relative to the fixed base is 180°.
