Description

Technical Field

[0001] The invention relates to the field of elevators, and in particular to a lower threshold structure of an elevator. Background Art

[0002] At present, there are generally two doors at the entrance and exit of a cabin elevator: the one on the landing side is called the landing door or hall door, and the one on the car side is called the car door. At the bottom of each door, there are sills and door guides to guide and limit the door panel so that the door panel can only move in a limited direction.

[0003] In actual applications, the mainstream sill has a guide groove set on the upper surface of the sill, opening upward, and cooperates with the door guide shoe set on the door panel, so that the door panel can only move in a limited direction. This type of structure is prone to accumulation of debris such as sand, dust, hair, and fiber fabrics, which can increase the resistance to door opening and closing and affect the service life of the door machine. In severe cases, it can cause door opening and closing failures, trapping people in the elevator, and other problems. In addition, since the sill guide groove opens upward and there is no structure to limit the upward movement of the door guide shoe, if a certain impact force is applied to the door panel, there is a risk that the door guide shoe will slip out of the guide groove and cause a fall. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, one of the objects of the present invention is to provide a lower threshold structure of an elevator, which can solve the problem of easy dust accumulation on the lower side of the door panel and low safety.

[0005] One of the purposes of the present invention is achieved by the following technical solution:

[0006] A lower threshold structure of an elevator includes a door panel, a guide shoe assembly, and a sill assembly. The guide shoe assembly includes a lower guide portion, a slider is arranged in the lower guide portion, a connecting edge is arranged on the upper portion of the lower guide portion toward the door panel, the connecting edge covers the upper portion of the lower guide portion, and a fitting plate fixed to the door panel is arranged on the upper side of the connecting edge; the sill assembly is located on the lower side of the door panel, the sill assembly is provided with a lower guide wall, and the lower guide wall is slidably mounted on the slider.

[0007] Furthermore, the lower guide portion is provided with a mounting groove, the sliding block is arranged in the mounting groove, the sliding block is provided with a guide groove, and the lower guide wall is slidably installed in the guide groove.

[0008] Furthermore, the lower portion of the lower guide portion is U-shaped.

[0009] Furthermore, the lower guide portion is in a hook shape.

[0010] Furthermore, the threshold assembly adopts a first threshold assembly, which includes a first threshold panel and a first threshold base plate fixed to the lower part of the first threshold panel, and a first lower edge guide wall is provided at the lower edge of the end of the threshold panel, and the first lower edge guide wall is slidably installed on the slider.

[0011] Furthermore, the first sill bottom plate includes two vertical bent edges, the lower parts of the two vertical bent edges are connected by a flat edge, and the tops of the two vertical bent edges are fixed to the first sill panel.

[0012] Furthermore, the sill assembly adopts a second sill assembly, the second sill assembly includes a second sill panel and a second sill bottom plate fixed to the lower part of the second sill panel, the second sill panel is flat, and the second sill bottom plate is provided with a lower guide wall.

[0013] Furthermore, the second sill bottom plate includes a first bending edge, a second bending edge, and a second lower edge guide wall, the first bending edge and the second bending edge are connected by a flat edge, and the second lower edge guide wall is located at the end of the second bending edge.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The guide shoe assembly includes a lower guide portion, a slider is arranged inside the lower guide portion, a connecting edge is arranged on the upper part of the lower guide portion toward the door panel, the connecting edge covers the upper part of the lower guide portion, and a fitting plate fixed to the door panel is arranged on the upper side of the connecting edge; the sill assembly is located on the lower side of the door panel, the sill assembly is provided with a lower guide wall, and the lower guide wall is slidably mounted on the slider. The connecting edge is used to cover the lower guide portion to prevent dust or debris from falling directly into the guide portion, thereby solving the problem of easy dust accumulation and low safety on the lower side of the door panel. There is no guide groove opening upward on the sill surface, thereby preventing debris from entering the guide groove and affecting the switch action of the elevator door system, which is conducive to reducing elevator door system failures and improving customers' elevator riding experience. At the same time, since there is no guide groove opening upward on the sill surface, it not only eliminates the trouble of cleaning the guide groove, but also makes it more beautiful and improves the appearance texture of the elevator.
