A safety lock device for a protective closed partition door in a subway section

Abstract

The invention relates to the field of subway seal doors, and particularly discloses a safe lock device of a protective and airtight partition door of subway interval. The safe lock device is connected with a seal door in a subway tunnel, and comprises a box body, a first occlusion element and a second occlusion element, wherein the box body is arranged at one side of the seal door; the first occlusion element is fixedly arranged at the lateral side of the seal door; one surface, which is opposite to the lateral side of the seal door, of the box body is provided with an opening; the second occlusion element is movably arranged in the box body and is opposite to the first occlusion element through the opening; the first occlusion element and the second occlusion element are respectively provided with a corresponding occlusion surface, and are occluded when being in contact. According to the invention, the relative position of the seal door and the box body is fixed by the first occlusion element and the second occlusion element which are provided with the occlusion surfaces, the degree of freedom of vertical rotation of the seal door can be eliminated completely, and thus the seal door cannot shake. A left wedge block and a right wedge block are driven manually by virtue of a relatively labor-saving worm box so as to guarantee the normal use of the safe lock device under the condition of outage.

Description

technical field [0001] The invention relates to the field of subway sealed doors, in particular to a safety lock device for a protective airtight partition door in a subway section. Background technique [0002] With the rapid development of rail transit, various forms of subway compartment partition doors are used in rail transit projects. The partition door in the existing subway section generally adopts a standard screw jack mechanism. The mechanism is equipped with a bolt. Support the self-weight of the door body to ensure that the door leaf will not be under cantilever force in the open and closed state for a long time, and ensure that the door leaf will not be deformed. But above-mentioned safety mechanism can not eliminate the rocking of door leaf in small range, also needs to fix door leaf with elements such as bolt, when causing opening and closing door leaf, process increases, and operation is loaded down with trivial details, and the time is longer.

Problems solved by technology

However, the above-mentioned safety mechanism cannot eliminate the shaking of the door leaf in a small range, and it is necessary to fix the door leaf with bolts and other components, resulting in more procedures, cumbersome operations and longer time when opening and closing the door leaf.
