LIMIT WHEEL DEVICE AND ELEVATOR FLOOR DOOR LOCK ASSEMBLY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/126799
Kind Code:
A1
Abstract:
A limit wheel device (30) and an elevator floor door lock assembly (1). The limit wheel device (30) is used for the elevator floor door lock assembly (1). The limit wheel device (30) comprises a limit wheel fixing rod (32) and a limit wheel (31). The limit wheel (31) comprises a sliding groove (311) which is approximately oblong and a rotary limit block (312) which projects out from the limit wheel (31) along the lengthwise direction of the sliding groove (311). The limit wheel (31) is mounted on one end of the limit wheel fixing rod (32) by means of the sliding groove (311). The lengthwise direction of the sliding groove (311) is approximately in a horizontal direction. The limit wheel (31) can move with relative to the limit wheel fixing rod (32) by means of the sliding groove (311). The limit wheel device (30) further comprises an elastic biasing means (33). The elastic biasing means (33) comprises an action part (332) abutting against a wheel edge (313) of the limit wheel along the horizontal direction. When the limit wheel fixing rod (32) is at the end of the sliding groove (311) close to the action part (332) of the elastic biasing means (33), the action part of the elastic biasing means (33) is in a balanced position. The action part (332) further comprises a rotary limit part (333) in coordination with the rotary limit block (312) of the limit wheel (31) and used for limiting the rotation of the limit wheel (31). When the positions in which two door vanes opening a door lock are inserted are not accurate enough, the deviation can be compensated for by means of the movement of the limit wheel (31) in the sliding groove (311), so that the safety of an elevator is improved.
