Abstract
An elevator door stiffener is characterized in that the diamond stiffener is fixed on the back of the door sheet of the elevator door by using the center line of the door sheet of the elevator door as symmetric line, the upper and lower ends of the stiffener are located between the upper and lower beams of the elevator door sheet, the left and right ends of the stiffener are located between the doorframes of the elevator door sheet, the diamond stiffener adopts welding method to weld square steel tube on the back of the door sheet of the elevator door, and decorative plates can also be mounted on the diamond stiffener for esthetic appearance. The elevator door stiffener has simple structure, is convenient for serialization and universal design of the door sheet, can effectively improve the strength of the elevator door, and make the door sheet run smoothly without vibrate beep.
Description
Technical field
The utility model elevator door refers in particular to a kind of elevator door reinforced rib.
Background technology
In the prior art; The reinforcing rib design of elevator door is fixed a reinforced rib at the back side of elevator door door-plate along its line of centers often, and the result who causes is, in the switch operational process of elevator; Door-plate can be because vibrations can be sent sound; If carrying heavy goods is run into elevator door because of carelessness, the elevator door door-plate also can be owing to insufficient strength deforms, even destroys door-plate.
Summary of the invention
The purpose of the utility model provides a kind of elevator door reinforced rib, improves the intensity of elevator door, and makes door-plate operate steadily, and can not send sound because of vibrations.
The utility model adopts following technical scheme:
A kind of elevator door reinforced rib comprises the elevator door door-plate, it is characterized in that: the line of centers with the elevator door door-plate is a symmetric line, is fixed with the rhombus reinforced rib at the back side of elevator door door-plate.
The two ends up and down of said rhombus reinforced rib are between the lower and upper cross-member of elevator door door-plate, and right ends is between the doorframe of elevator door door-plate.
The mode that described rhombus reinforced rib adopts welding is welded on the back side of elevator door door-plate with rectangular steel tube, for attractive in appearance, can also on the rhombus reinforced rib, install trim board.
The related reinforcing rib structure of the utility model is simple, is convenient to the seriation and the General design of door-plate, can actv. improves the intensity of elevator door, makes door-plate operate steadily, and can not send sound because of vibrations.
Description of drawings
Fig. 1 is the structural representation of elevator door reinforced rib;
Fig. 2 is the schematic cross-section of elevator door reinforced rib;
1, crossbeam; 2, door-plate; 3, rhombus reinforced rib; 4, following shrouding; 5, doorframe.
The specific embodiment
As shown in Figure 1; Elevator door is made up of door-plate 2, doorframe 5, crossbeam 1, rhombus reinforced rib 3 and following shrouding 4; Rhombus reinforced rib 3 is the back side that symmetric line is welded on door-plate 2 with the line of centers of elevator door door-plate 2; The upper and lower top of rhombus reinforced rib 3 is near the crossbeam 1 of upper/lower terminal, and the top, the left and right sides of rhombus reinforced rib 3 is near doorframe 5.Rhombus reinforced rib 3 is formed by 1.5mm steel plate flanging, and is as shown in Figure 2, and protruding upper end width is 60mm, and protruding lower end width is 100mm, and hill height is 33mm.For attractive in appearance, can also on rhombus reinforced rib 3, install trim board, the thickness that the hill height of rectangular steel tube adds upper decoration plate equals the height of doorframe 5, adopts the structure design of the utility model, can make elevator door more solid, moves more steady.
