Description

Elevator landing door device cover

technical field

The utility model relates to a device used for an elevator; in particular, it relates to a cover plate used for a landing door device of an elevator.

Background technique

The main function of the elevator landing door device cover plate is to protect the landing door guide rail and switch, prevent dust and other debris from entering, and avoid causing electrical switch failure. Most of the existing elevator floor door device cover plates are made of metal or resin materials.

When using metal materials, in order to ensure that the plate is not easy to deform when it is thin, the overall transverse bending is generally used to strengthen the strength, but this process is difficult to ensure that it is not easy to deform when the plate is particularly thin.

When using resin materials, in order to ensure that it is not easy to deform, the plate thickness is thicker than that of metal materials. The advantage is that the price is relatively cheap, but the disadvantage is that resin materials are prone to aging and deformation after long-term use.

The existing first elevator floor door device cover plate shown in Figure 1 is made of metal, and in order to strengthen its strength, a transverse bending is adopted; but the disadvantage of adopting this transverse bending structure is that the plate of the cover plate thicker, the strength of the cover plate is insufficient.

The existing second elevator landing door device cover plate shown in Figure 2 is made of metal, and in order to strengthen its strength, it adopts multiple transverse bendings; only by adopting this multi-channel transverse bending structure can it reduce to a certain extent Plate thickness, but the strength of such a cover plate is still insufficient.

The existing third elevator floor door device cover plate shown in Figure 3 is made of resin material and is extruded; the disadvantage of this structure is that the strength of the resin material itself is insufficient, so it is necessary to meet the strength requirements of the cover plate. It is necessary to design a thicker board; and the resin material is more prone to aging than the metal material, and needs to be replaced frequently after a period of use.

The existing fourth kind of elevator floor door device cover plate shown in Figure 4 is made of composite material; its upper part is made of metal material, and the lower part is made of resin material; The material and the resin material are combined, so the process is complicated; and the lower resin material is easy to age and needs to be replaced frequently.

Therefore, need to design a kind of simple in structure at present, can reduce the plate thickness, and with low cost, easy to install elevator floor door device cover plate.

Utility model content

The technical problem to be solved by the utility model is to provide a cover plate for an elevator floor door device, which can greatly reduce the thickness of the plate, is low in cost, and is easy to install.

In order to solve the above technical problems, the utility model provides a cover plate of an elevator landing door device, which includes a cover plate body, and a closed three-dimensional cavity formed by metal stamping concave and convex is arranged on the cover plate body.

The beneficial effect of the elevator landing door device cover plate of the utility model is that: this structure makes the cover plate body have good bending strength in directions such as up, down, left, and right; the thickness of the plate can be greatly reduced, the cost is low, and it is easy to install.

Preferably, the cavity is a closed cavity with a wide upper part and a narrower lower part.

Preferably, the cavity is a "concave" closed cavity.

Preferably, the cavity is a rectangular closed cavity.

Preferably, the cavity is a combination of multiple rectangular closed cavities.

Preferably, the cover body has holes.

Preferably, the holes on the cover body are gourd-shaped holes.

Preferably, the holes on the cover body are multiple gourd-shaped holes.

Preferably, the holes on the cover body are two gourd-shaped holes.

Preferably, the two gourd-shaped holes on the cover body are through holes located on one side of the cover body.
