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.

    本发明公开了一种电梯轿厢门气密装置,包括第一轿门、第二轿门、凸形结构、减震装置、橡胶板螺孔、橡胶板、充气橡胶、凹形槽、气流管道、电源线、充气泵、气流孔、伸缩罩、伸缩杆、伸缩杆螺孔、伸缩杆座、和杆座螺孔。本发明的有益效果是:过在第一轿门一端设置凸形结构,且在第二轿门一端设置凹形槽,使得门之间的连接更加稳固,通过在凸形结构异常设置减震装置,且在减震装置一端设置橡胶板,使得凸形结构与凹形槽在卡合时,所产生的冲击效果,从而使轿门关闭时更加安全稳固,增加了轿门的使用寿命,通过在第二轿门一端设置充气橡胶,使得轿门关闭时,能够进行气密工作。装置具有安全稳定性高,气密效果更佳的特点。
