Description

Elevator door structure Technical Field The utility model belongs to the technical field of elevator production, and particularly relates to an elevator door structure. Background The elevator door is usually hung in a sliding manner and is arranged at the opening of the elevator car, and the automatic opening and closing of the elevator door are controlled through the driving mechanism, so that shaking is generated in the opening and closing process of the elevator door, a strip-shaped sliding groove is formed in the bottom of the opening of the elevator car, a plurality of guide posts matched with the strip-shaped sliding groove are usually arranged at the bottom of the elevator door in a rotating manner, and when the elevator door is opened and closed, the guide posts can only slide along the strip-shaped groove, so that shaking of the elevator door can be prevented. However, after the guide post is used for a long time, damage may occur, such as serious abrasion or incapacitation of rotation.

Further, the baffle includes first baffle and second baffle, and first baffle top is located to the second baffle, and the top at first baffle both ends is located to the bulge, and first baffle passes through screw connection with the dead lever. Further, the first baffle is including the upper segment and the hypomere that all are rectangle form, and the thickness of hypomere matches with the thickness of bending segment, hypomere top height and dead lever top high-match, and the thickness of upper segment is greater than the thickness of buckling, and the inboard protrusion of upper segment is in the inboard of hypomere, and the dead lever top is equipped with the connecting block, and the counter bore has been seted up in the upper segment outside for the head of holding screw, screw pass counter bore and connecting block threaded connection, and the screw is interior angle screw. Further, a plurality of guide posts tops are connected with a plurality of spliced poles through the pivot respectively, and a plurality of spliced poles all pass dead lever top and are connected with a plurality of second spacing pieces, and second spacing piece bottom and dead lever top butt, second spacing piece top and clamp plate butt. Further, the diameter of the guide post is less than or equal to the diameter of the connecting post. The utility model has the beneficial effects that: When the guide post of this elevator door structure replacement bottom, need not take off the elevator door from the elevator car, take off the baffle, then upwards lift up the dead lever to breach department can take out dead lever and guide post, carry out the change of guide post, can improve the change efficiency of guide post.
