To provide a support which allows a floor to be placed above one of the clamping parts and allows a door frame or the like to be easily placed above the other clamping part. [Solution] The support 16A comprises a first clamping portion 17A having a pair of opposing first plate-shaped portions 17aA, 17bA, a second clamping portion 18A having a pair of opposing second plate-shaped portions 18aA, 18bA arranged opposite the first clamping portion, and a bottom portion 19A connected to the lower ends of the first clamping portion and the second clamping portion, respectively, and the height of the first clamping portion is greater than the height of the second clamping portion.

The side sliding door with the shaking prevention function comprises a door frame and a door body, the door frame and the door body are rotationally connected through a rotating shaft rod, the door frame is provided with a first single sliding rail and a second single sliding rail which are in rolling fit with the door body, and a supporting position is defined at the lower end of the door body; when the door body is pushed to drive the supporting position of the door body to move along the second single sliding rail, the upper end of the door body moves along the first single sliding rail. Through cooperation of the first single sliding rail, the second single sliding rail, the rotating shaft rod and other structures, in the moving process of the door body, the upper end of the door body and the first single sliding rail are provided with supporting points, and a second supporting point is arranged between the lower end of the door body and the second single sliding rail, so that even if a heavy glass door is used, the door body is not prone to falling off. The phenomenon of shaking does not occur in the moving process; the first single sliding rail and the second single sliding rail do not need to be arranged to be of an existing L-shaped structure, the structure is simple, and the production cost is effectively reduced.

The utility model relates to a steel double-leaf flood-proof door which comprises a door frame, door leaves, an upper bolt clamping mechanism and a lower bolt clamping mechanism, the upper bolt clamping mechanism and the lower bolt clamping mechanism are arranged on the door leaves, a lower doorsill of the door frame is buried in a terrace, and the upper surface of the door frame is flush with the terrace; the upper part of the lower doorsill is provided with a plurality of openings for inserting bolts; the upper and lower bolt clamping mechanism comprises a bolt, a movable sinking water retaining block which moves up and down synchronously with the bolt is fixedly arranged on the bolt, the movable sinking water retaining block is in an L shape, the bottom face of the movable sinking water retaining block can cover the upper surface of the lower doorsill, and a rubber sealing piece is arranged on the side face of the movable sinking water retaining block to be attached to the door leaf. The lower doorsill is pre-buried in the terrace and kept on the terrace, when the plug pin is downwards inserted into the lower doorsill, the L-shaped movable sinking water retaining block moves downwards together, the bottom face of the L-shaped movable sinking water retaining block presses the lower doorsill, meanwhile, the side face of the L-shaped movable sinking water retaining block blocks a door crack in the bottom of the door leaf, and the good sealing and flood preventing functions are achieved.
