Embodiment Construction

[0025] The trap door of the driving station or steering station, as shown in Figures 1 to 3, includes a door panel 1 and a hinge 2. The hinge 2 is hidden under the door panel 1, and the hinge 2 is connected between the door panel 1 and the truss 4. 2 is a double-rocker plane four-bar mechanism, which is hinged by four hinge rods 5, 6, 7, and 8. The sum of the length of the shortest hinge rod 5 and the length of the longest hinge rod 6 is less than or equal to hinge rod 7 and hinge rod 8. The sum of lengths, in which the shortest hinge rod 5 is directly or indirectly fixedly connected to the door panel 1, the shortest hinge rod is directly or indirectly fixedly connected to the truss 4, and the shortest hinge rod may be directly or indirectly connected to the truss 4 The door panel frame 3 is fixedly connected, so that the door panel 1 and the hinge 2 connected thereto constitute a trap door that is folded and opened. When the trap door is opened, the movement mechanism of the hing...

Abstract

The invention provides a trapdoor for driving station or turning-over station, which comprises a door sheet (1) and a hinge (2), wherein the hinge (2) is equipped below the door sheet (1) in hidden way, the hinge (2) is a plane four bar mechanism hinged by four hinge rods (5, 6, 7, 8), the shortest hinge rod (5) is directly or indirectly fixedly connected with the door sheet (1), the hinge rod (7) opposite to the shortest hinge rod is directly or indirectly fixedly connected with a truss (4) or a door sheet frame (3), thus the door sheet (1) and the hinge rod (2) connected therewith form a trapdoor capable of being opened in folding way. The invention has unique design, and is easy to realize the opening of the trapdoor. The invention can be very conveniently used, does not affect esthetic appearance, and has good application prospects.

Description

Technical field [0001] The present invention relates to a trap door, in particular to a trap door arranged on an escalator or moving walkway driving station or steering station. Background technique [0002] In the prior art, trapdoors installed on escalators or moving walkways driving stations or steering stations usually have their door panels directly placed on the door panel frame without a hinge structure. When opening the door panels of the trapdoor, all the door panels need to be removed , More time-consuming and laborious, extremely inconvenient to use. [0003] Of course, even if some trapdoors use a hinge structure, their hinges are single-axis hinges. In order to prevent the trapdoor from interfering with the door frame when the trapdoor is opened, the hinge cannot be hidden and installed under the door panel so that passengers can see directly The hinge affects the aesthetics. [0004] Therefore, designing a new type of drive station or steering station upper trap doo...
