Technical Field

[0001] The utility model relates to the technical field of elevator cars, in particular to a hand pinching prevention device for a side seam of a vertical elevator car door. Background Art

[0002] A vertical elevator car is a component for transporting passengers and goods, and is a device that runs between at least two vertical rigid guide rails or with an angle of inclination less than 15°. As the core part of a transportation tool, the design and function of a vertical elevator car are intended to provide safe and efficient vertical transportation services for people and goods. From structure to technical application, the development of modern elevator cars demonstrates the convenience and safety brought by scientific and technological progress.

[0003] When the existing vertical elevator cars are in operation, some of the gaps between the car and the side of the door body are large. When the door is opened, children who are not supervised by their parents may accidentally have their fingers further caught in the side gap as the door opens. Therefore, it is necessary to provide a vertical elevator car door side gap anti-pinch device to avoid pinching children's fingers and improve the safety of the elevator car when in use. Utility Model Content

[0004] The purpose of the utility model is to provide a device for preventing fingers from being pinched in the side gap of a vertical elevator car door, so as to solve the problem raised in the above-mentioned background technology that, when the existing vertical elevator cars are in operation, some gaps between the car and the side of the door body are relatively large, and when the door is opened, children who are not supervised by their parents may accidentally have their fingers further rolled into the side gap as the door opens.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a vertical elevator car door side seam anti-pinch hand device, comprising:

[0007] A main body assembly, the main body assembly comprising a car wall and a door opening;

[0008] The door opening is opened in the lower middle section of the car wall;

[0009] An anti-pinch assembly, the anti-pinch assembly comprising a strong suction cup, a first connecting rod, a second connecting rod, a support plate, a movable plate, a spring, a first anti-collision strip and a second anti-collision strip;

[0010] The strong suction cup is adsorbed on the side of the car wall, the first connecting rod is welded between the two strong suction cups, one end of the second connecting rod is welded to the first connecting rod, the support plate is movably connected to the side of the second connecting rod, the movable plate is hinged on the side of the support plate away from the second connecting rod, both ends of the spring are fixed to the support plate and the side of the movable plate, the first anti-collision strip is fixed to one end of the support plate away from the strong suction cup, and the second anti-collision strip is fixed to one end of the movable plate away from the support plate.

[0011] Furthermore, there are five movable plates in total, and each movable plate corresponds to two springs.

[0012] Furthermore, there are two groups of anti-pinch components, which are respectively located on both sides of the door opening and in the middle and lower section of the door opening.

[0013] Furthermore, the main body assembly also includes a movable compartment and a double door;

[0014] The movable bins are arranged on both sides of the door opening, and the double doors are slidably connected in the door opening and the movable bins.

[0015] Furthermore, the support plate and the movable plate are located on the inner side of the door opening, and the second anti-collision strip on the movable plate is close to the double-opening door.

[0016] Further, it also includes an adjustment component;

[0017] The adjustment assembly includes a fixing plate, a through hole, an adjustment rod and a third anti-collision strip;

[0018] The side edge of the fixed plate is welded to the end of the second connecting rod away from the first connecting rod, a through hole is opened in the middle of the fixed plate, the adjusting rod is screwed in the through hole, and one end of the adjusting rod rotates the support plate away from the side of the movable plate, and the third anti-collision strip is fixed to the end of the fixed plate away from the strong suction cup.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The utility model fixes a strong suction cup on the wall of the car and is located on the side of the door opening through an anti-pinch component. At this time, the movable plate on the support plate is located on the side of the double-opening door. When a finger is extended to the side door gap of the double-opening door and touches the movable plate, the movable plate is driven to rotate toward the movable bin, so that the second anti-collision strip fits the double-opening door. Due to the friction resistance of the second anti-collision strip, the double-opening door cannot be opened. The first connecting rod and the second connecting rod play a connecting role. The first anti-collision strip avoids injuring passengers. This arrangement can avoid pinching children's fingers and improve the safety of the elevator car.

[0021] 2. The utility model uses an adjustment component to rotate the adjustment rod in the through hole to make the support plate close to or away from the fixed plate, thereby adjusting the position of the movable plate. This setting allows the anti-pinch component to adapt to different car wall thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS
