Abstract

The utility model belongs to the technical field of waterproof doorsills, and particularly relates to a hidden upturned doorsill of a subway flood gate, which comprises a doorsill base, wherein the doorsill base is embedded in concrete ground, and an upturned cover plate is arranged in a notch in the inner wall of the doorsill base; when the utility model is used, the handle on the upper turnover cover plate is pulled, so that the handle can drive the upper turnover cover plate to turn over towards the opening end of the threshold base. When the upper flip plate is turned over, the upper flip plate can be turned over smoothly through four groups of hinges, and one end of the upper flip plate can be carried with the opening end of the threshold base after the upper flip plate is turned over. The tight device in top on the threshold base can be with going up flip board top fastening and fix the open end at the threshold base this moment, go up flip board's one end in addition can support on the stagnant water adhesive tape, goes up flip board one side's stagnant water adhesive tape simultaneously also can extrude on threshold base open end inner wall, just so realized the effect that flip board was hidden and was revealed on convenient operation.

Description

Hidden upturning type threshold of subway flood-proof door Technical Field The utility model belongs to the technical field of waterproof doorsills, and particularly relates to a hidden upturned doorsill of a subway flood-proof door. Background The hidden up-turning type threshold of the subway flood gate is commonly used for garage ports, subway ports and underground passage ports with serious flood disasters and is used for isolating water bodies so that flood cannot infiltrate into buildings, and in the subway operation process, the subway flood gate plays a vital role in preventing water from entering the subway due to natural disasters such as sudden flood, storm and the like and threatening the safety of subway facilities and passengers; the existing subway flood-proof door threshold is of a fixed structure, when the subway flood-proof door threshold is not used, the fixed door threshold protrudes from the ground, normal traffic of the subway is affected, particularly, passengers carrying large pieces of luggage and inconvenient-to-move people pass through the subway, large potential safety hazards exist, the movable door threshold structure is partially involved, operation is complex, time consumption for opening and closing processes is long, flood-proof deployment is difficult to rapidly complete under emergency conditions, sealing performance is poor, and water flow infiltration cannot be effectively prevented. Disclosure of utility model The utility model aims to provide a hidden upturned threshold of a subway flood gate, which aims to solve the problems that most of existing subway flood gate thresholds are of a fixed structure, when not in use, the fixed threshold can be raised on the ground to influence the normal traffic of a subway, and particularly, the traffic of passengers carrying large pieces of luggage and inconvenient people exist, so that the hidden safety hidden danger exists, and the partially movable threshold structure has the defects of complex operation, long time consumption in opening and closing processes, difficulty in rapidly completing flood deployment under emergency conditions, poor sealing performance and incapability of effectively preventing water flow infiltration. In order to achieve the aim, the utility model provides the technical scheme that the hidden upturning type threshold of the subway flood gate comprises a threshold base, wherein the threshold base is embedded into the concrete ground, and an upturning cover plate is arranged in a notch on the inner wall of the threshold base; Four hinges are arranged in the included angle between the upper turnover cover plate and the connecting end of the threshold base, and each hinge is in butt joint with the threshold base and the upper turnover cover plate through two bolts respectively. As the hidden upturned threshold of the subway flood gate, preferably, one side of the inner wall of the threshold base is provided with a downward groove, and the bottom of the upturned cover plate is inserted into the groove; the upper side of recess one side is provided with the stagnant water adhesive tape, the opposite side of stagnant water adhesive tape bonds on the outer wall of threshold base, go up flip board and go up the outer wall closely laminating of flip board when pegging graft in the middle of the recess. As the hidden upturning type threshold of the subway flood-proof door, preferably, a rectangular opening is formed in the outer wall of one side, far away from the upturning cover plate, of the threshold base, a jacking device is arranged in the rectangular opening, and a handle is arranged on the outer wall of one end, far away from the water stop adhesive tape, of the upturning cover plate. Compared with the prior art, the utility model has the beneficial effects that: When the handle is used, the handle on the upper turnover cover plate is pulled, so that the handle can drive the upper turnover cover plate to turn over towards the opening end of the threshold base. When the upper flip plate is turned over, the upper flip plate can be turned over smoothly through four groups of hinges, and one end of the upper flip plate can be carried with the opening end of the threshold base after the upper flip plate is turned over. The tight device in top on the threshold base can be with going up flip board top fastening and fix the open end at the threshold base this moment, go up flip board's one end in addition can support on the stagnant water adhesive tape, goes up flip board one side's stagnant water adhesive tape simultaneously also can extrude on threshold base open end inner wall, just so realized the effect that flip board was hidden and was revealed on convenient operation.
