The invention discloses a safety elevator door structure for an elevator. The safety elevator door structure for the elevator comprises a first door body and a second door body. A groove is formed inthe first door body, and a protruding block matched with the groove is arranged in the second door body. The protruding block is inserted into the second door body, a ventilation opening is formed inthe portion, in the second door body, of the protruding block, and a cavity is formed in the protruding block. Two sides of the cavity are each fixedly connected with a current-conducting plate, the two current-conducting plates are electrically connected with an external power supply device, and the sides, far away from each other, of the two current-conducting plates communicate with detection chambers. A laser transmitter is fixedly connected with the interior of each detection chamber, and the two detection chambers are jointly connected with a plurality of thermoelectric rods. The sides,away from each other, of the two detection chambers are each provided with a connector. The structure has the advantages that the carbon dioxide concentrations inside and outside the elevator can be detected in a power-off state, the automatic door opening and ventilation effect is achieved in the state that the difference value of the carbon dioxide concentrations inside and outside the elevatoris large, and the indoor environment is prevented from affecting normal breathing of trapped people.

    本发明公开了一种电梯用安全电梯门结构,包括第一门体和第二门体,所述第一门体中开设有凹槽并且第二门体中设有与凹槽配合的凸块,所述凸块插设至第二门体中并且在第二门体内的部分设有透气口,所述凸块中开设有空腔,所述空腔的两侧分别固定连接有一个导电板,两个所述导电板分别与外界供电装置电连接,两个所述导电板相互远离的一侧连通开设有检测室,所述检测室中固定连接有激光发射器,两个所述检测室共同连接有多个热电棒,两个所述检测室相互远离的一侧分别开设有连接口。优点在于:可以在断电状态下对电梯内外的二氧化碳浓度进行检测,在两者差值较大的状态下实现自动开门通风的作用,避免室内环境影响滞留人员的正常呼吸。
