Description

Technical Field

[0001] This utility model relates to the field of passenger elevator platform canopy technology, and in particular to a hand-cranked control opening and closing component and a passenger elevator platform canopy. Background Technology

[0002] Passenger boarding stairs are essential ground support equipment in airports for passengers, crew members, and baggage handlers to board and disembark aircraft, playing a crucial role, especially when the aircraft is not parked at a jet bridge (remote parking position). In existing technology, some passenger boarding stairs platforms are equipped with adjustable canopies to provide shelter from rain and snow, facilitating passenger boarding and disembarking.

[0003] Most passenger boarding bridge platform canopies use automatic adjustment methods. However, electric opening and closing systems have high maintenance costs. In remote airports or scenarios with unstable power supply, the electric system may fail to work properly due to power outages, limiting the applicability of the equipment. Electric opening and closing systems need to integrate multiple components such as motors, controllers, and sensors, which increases the equipment failure rate and the technical threshold for maintenance.

[0004] Therefore, we propose a hand-cranked control opening and closing component and a passenger elevator platform canopy. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies, such as high maintenance costs for electric opening and closing systems, the possibility that electric systems may fail to function properly due to power outages in remote airports or scenarios with unstable power supply, which limits the applicability of the equipment, and the need to integrate multiple components such as motors, controllers and sensors into electric opening and closing systems, which increases the equipment failure rate and the technical threshold for maintenance. Therefore, this invention proposes a hand-cranked control opening and closing component and a canopy for passenger boarding stairs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hand-cranked opening and closing component, comprising:

[0008] The fixed rod and the mounting block are provided. The outer wall of the fixed rod is rotatably fitted with a movable shell and a movable tube. A sliding rod is slidably connected to the inner wall of one side of the movable shell. A toothed rack is fixedly embedded on the surface of the sliding rod through a relief groove. A connecting seat is rotatably connected to one end of the sliding rod.

[0009] One end of the movable tube extends into the movable housing and is fixed with a gear. The gear meshes with the rack. An adjustment mechanism is provided on one side of the movable tube to adjust the rotation of the movable tube.

[0010] In one possible design, the adjustment mechanism includes a rotating shaft rotatably connected to one side of the mounting block. Both the rotating shaft and the outer wall of the movable tube are fixedly fitted with synchronous pulleys. The two synchronous pulleys are connected by a synchronous belt drive. A fixed disc is fixedly mounted on one side of the rotating shaft. An adjustment rod slides through one side of the fixed disc. A spring is fixed between the adjustment rod and the fixed disc, and the spring is fitted onto the adjustment rod.

[0011] In one possible design, a fixing ring is fixed on one side of the mounting block, and multiple positioning grooves are opened on one side of the fixing ring, with one end of the adjusting rod located in one of the positioning grooves.

[0012] In one possible design, one end of the adjusting rod is fixedly fitted with a rubber sleeve.

[0013] A passenger elevator platform canopy includes a hand-cranked opening and closing assembly, two parallel bases, a common bracket fixed between the two bases, a cover plate fixed to the outside of the bracket, two ends of a fixing rod fixed to the inner walls of the two sides of the bracket, and a mounting block fixed to the inner wall of one side of the bracket, the mounting block being located below the fixing rod.

[0014] A rotating rod is rotatably connected between the two bases. The connecting seat is fixed on the top inner wall of the rotating rod. A canvas is fixed between the rotating rod and the bracket. A connecting rod is fixed between the bracket and the two bases. Multiple support mechanisms for supporting the canvas are provided between the two connecting rods.

[0015] In one possible design, the support mechanism includes two movable sleeves, each sleeved onto a connecting rod, with a common support rod fixed between the two movable sleeves, and the inner wall of the support rod fixed to the outer side of the canvas.

[0016] In one possible design, the surface of the base has multiple mounting holes, which are countersunk holes.

[0017] In one possible design, the tops of the bracket, rotating rod, and support rod are all tapered.

[0018] In this application, when unfolding the awning, the rubber sleeve is held by hand to move the adjusting rod, causing the adjusting rod to disengage from the positioning groove. Then, the adjusting rod drives the fixed plate and the rotating shaft to rotate. Under the action of the synchronous pulley and the synchronous belt, the movable tube and the gear rotate. The gear drives the rack to move, causing the slide rod and the movable shell to slide relative to each other. One end of the slide rod pushes the connecting seat and the rotating rod to rotate, thereby driving the awning to unfold. Then, the adjusting rod is pushed into the corresponding positioning groove to prevent the fixed plate and the rotating shaft from rotating, thus keeping the awning stable. The operation is the same when retracting the awning; simply rotate the adjusting rod in the opposite direction.

[0019] Beneficial effects: In this utility model, the hand-cranked control opening and closing component and passenger elevator platform canopy, through the setting of multiple structures such as fixed rods, movable shells and connecting seats, avoids the problem of damage to electric equipment in harsh environments such as high humidity, and reduces the maintenance cost of the structure;

[0020] In this utility model, the hand-cranked opening and closing component and passenger elevator platform canopy are designed with multiple structures such as adjusting rod, fixed plate and rotating shaft. People only need to pull out the adjusting rod to drive the fixed plate to rotate, and then insert the adjusting rod back into the positioning groove to control the opening and closing of the canopy. The operation is simple and convenient, providing convenience for people.

[0021] This invention avoids the problem of electric equipment being easily damaged in harsh environments such as high humidity, reduces the maintenance cost of the structure, and makes the operation of controlling the opening and closing of the canopy simple and convenient, providing convenience for people.
