Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that when the temperature of the working environment changes greatly, the glue or double-sided tape will peel off, causing the reinforcing rib to separate from the door panel, thereby deforming the door panel and affecting the opening and closing of the elevator door. A new type of elevator landing door panel assembly proposed

Embodiment approach

[0033] As an embodiment of the present invention, the floor door panel assembly is made by the following method:

[0034] S1: Add raw materials BMC or SMC to the injection molding machine first, or add materials to other auxiliary equipment; the linear expansion coefficient of raw materials is smaller than that of ordinary thermoplastics, so it has high dimensional stability and dimensional accuracy; its tensile The tensile, bending, impact strength and other properties are higher than thermoplastics, and the creep resistance is also better than thermoplastics; the high strength, milk acid and alkali salt, aging resistance and other characteristics of the material are very suitable for the use environment of elevator landing doors;

[0035] S2: heating the mold of the product to 130-150°C;

[0036] S3: Put the material into the heated mold through the injection molding machine or other auxiliary equipment;

[0037] S4: The mold is heated to solidify the material, and the form...

Abstract

The invention belongs to the technical field of elevator equipment, and particularly relates to a novel elevator landing door plate assembly which comprises a landing door plate assembly body. The landing door plate assembly body comprises a landing door plate, reinforcing ribs and guide shoe plates. The multiple sets of reinforcing ribs are fixedly connected to the landing door plate. The reinforcing ribs are arranged on the landing door plate in a latticed manner. The multiple sets of guide shoe plates are fixedly connected to the bottom of the landing door plate. By using a non-metal high polymer material, an anti-rust coating does not need to be additionally sprayed after the landing door plate assembly body is formed, and the material has very good corrosion resistance such as acid, alkali and salt resistance and meanwhile has very good environmental aging resistance; the surface color of the landing door plate assembly body can be changed by mixing colors of the material; and various colors can be mixed according to the requirements of customers, and selectable diversity is achieved.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment, in particular to a novel elevator floor door panel assembly. Background technique [0002] As the level of social urbanization is getting higher and higher, and the process of urbanization is getting faster and faster, more and more high-rise buildings are rising. Elevators, as an indispensable modern transportation tool, are inseparable from people's life and work. [0003] There are also some technical solutions about elevator landing doors in the prior art. For example, a Chinese patent with application number 2015103873038 discloses an elevator landing door with door panel interlocking device, including a pair of door panels. The top of the pair of door panels can pass through The door lock device for opening and locking is interlocked, and the bottom is interlocked by an interlock device capable of opening and locking. The opening and locking actions of the interlock device and th...
