Benefits of technology

The technical feature described by this new design improves how well an elevators' strokes have been improved over previous designs due to their being sealed from external moist environments or rainwater damage during use. This results in longer lifespan for the elevation machine without any leaks caused through its own mechanism.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the construction of conventional travel switches for industrial machines without compromising safety standards requirements. These known devices have limitations like being too rigidly designed, lacked responsiveness during prolonged usage environments, insufficient sealing against moisture penetration, high maintenance costs associated therewith, etc., which affect their overall durability over time.

Abstract

The invention relates to the technical field of electric appliance control,, in particular to a portable waterproof travel switch. A leather sheath is arranged between a push rod cap and a shell; theouter edge of one end of the lower part of the leather sheath is matched with a circular groove around a shell circular hole; a groove is formed in the outer edge of the lower part of the leather sheath; the outer edge of the bottom of the leather sheath is barb-shaped; the lower part of a rear cover of the shell is provided with an external thread; sealing rubber is arranged in a cavity of the external thread; a sealing ring is arranged in the cavity of the external thread; the upper portion of the sealing ring abuts against the sealing rubber. The external thread extends out of the lower part of the sealing ring; the bottom of the external thread is connected with the internal thread of a thread cover; the threaded cover moves upwards to drive the sealing ring to move upwards and extrudethe sealing rubber, the sealing rubber deforms and extrudes towards the middle when bearing external force, many structural improvements are conducted on an existing elevator stroke, the waterproof effect of the elevator stroke is better, the service life is prolonged, and meanwhile more safety problems caused by water leakage can be avoided.
