Elevator car door airtight device

Abstract

The invention discloses an elevator car door airtight device. A first car door, a second car door, an inverted-T-shaped structure, damping devices, rubber plate screw holes, a rubber plate, inflationrubber, a U-shaped groove, an airflow pipeline, a power line, an inflation pump, an airflow hole, a telescopic cover, a telescopic rod, a telescopic rod screw hole, a telescopic rod base and rod basescrew holes are included. The elevator car door airtight device has the beneficial effects that the inverted-T-shaped structure is arranged at one end of the first car door, the U-shaped groove is formed in one end of the second car door, and therefore door connection is more stable; one side of the inverted-T-shaped structure is provided with the damping devices, the rubber plate is arranged at one ends of the damping devices, so that when the inverted-T-shaped structure and the U-shaped groove are clamped, the impact effect is generated, more safety and stability are achieved during car doorclosing, and the service life of the car doors is prolonged; and the inflation rubber is arranged at one end of the second car door, so that during car door closing, airtight work can be conducted. The device has the characteristics that safe stability is high, and the airtight effect is better.

Description

technical field [0001] The invention relates to an airtight device, in particular to an elevator car door airtight device, which belongs to the field of elevator transportation applications. Background technique [0002] An elevator refers to a fixed lifting device that serves certain floors in a building and serves a specified floor. The vertical elevator has a car. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use it regardless of its driving method. How to use the elevator as a general term for vertical transportation in buildings. Hydraulic elevators began to appear in the middle of the 9th century. In the 1980s, the drive device was further improved, such as the motor driving the winding reel through the worm drive, using a balance weight, etc. At the end of the 19th century, The friction wheel transmission is adopted, which greatly increases the lifting height of the elevator. The eleva...
