The elevator landing door panel structure provided by the embodiment of the utility model is explained. Elevators have become indispensable facilities of modern buildings, and great convenience is brought to people going upstairs and downstairs and transporting goods. The elevator landing door structure is an indispensable important accessory of an elevator, the elevator landing door structure is arranged at an elevator lobby, the landing door is in a normally closed state, and when the elevator reaches a floor corresponding to the landing door, the landing door is opened, and passengers can enter a car of the elevator. The landing door has certain self-closing force, and the landing door is forced to be closed, so that the landing door is prevented from being opened randomly to cause danger. The self-closing force of closing door of elevator waiting room landing door can be provided by gliding weight in the stand pipe, certain self-closing force has in order to guarantee the landing door, force the landing door closure, prevent that the landing door from being opened at will and danger appears, in the mounting structure of traction formula elevator, traction formula elevator landing door structure will set up elevator weight guide structure usually, and the additional strengthening of elevator weight guide structure and landing door often sets up same one side at the landing door, elevator weight guide structure is great, need great installation space, when additional strengthening design is unreasonable, easily interfere with elevator weight guide structure. Especially when the layer door is higher, and its intensity is more weak, need set up more additional strengthening in vertical direction and guarantee the intensity of layer door, prevents that the layer door warp. Thus, after the reinforcing structure is installed on the landing door, the residual space for installing the weight guide structure is less.

In one embodiment of the present invention, referring to fig. 1 and 2, the door panel structure of the landing door comprises a door panel main body 1, a reinforcing rib 2, a support plate 3 and a weight guide structure 4. Door plant main part 1 is the main structure of elevator layer door panel structure, and strengthening rib 2, backup pad 3 and weight guide structure 4 all set up on door plant main part 1, specifically speaking, strengthening rib 2, backup pad 3 and weight guide structure 4 all set up the inboard at door plant main part 1, and the inboard of door plant main part 1 is the one side towards car sedan-chair door. Door plant main part 1 is the rectangle, and door plant main part 1 has broadside and long limit, and the vertical setting in long limit, long limit direction are door plant main part 1's direction of height, and the broadside level sets up, and the broadside direction is door plant main part 1's direction of width.

The reinforcing rib 2 is fixed to the door panel main body 1 at a middle position in the width direction thereof, and in reference to fig. 1, the reinforcing rib 2 is provided at a middle position in the left-right direction of the door panel main body 1. The middle position of the door panel main body 1 along the width direction thereof is a position which is not located on two long sides of the door panel main body 1, is not necessarily a center line position of the door panel main body 1 along the width direction thereof, and can be arranged to be deviated to the left or right, namely, is a position close to the center line. The length direction of the reinforcing ribs 2 is parallel to the height direction of the door panel main body 1, namely, the reinforcing ribs 2 are vertically arranged.

The quantity of backup pad 3 is two, sets up respectively in the left and right sides of door plant main part 1, and two backup pads 3 can replace the enhancement function of one or more strengthening rib 2, make door plant main part 1 when intensity is not enough, can realize comparatively effectual support. The supporting plate 3 can be a long strip shape, and the length extending direction of the supporting plate 3 is parallel to the height direction of the door panel main body 1, namely the supporting plate 3 is vertically arranged. The weight guide structure 4 is disposed on the door panel body 1, wherein the reinforcing rib 2 is fixed in the middle of the door panel body 1, and therefore, the reinforcing rib 2 has a mounting space on both sides for the weight guide structure 4 to be mounted, and the weight guide structure 4 can be mounted on the left or right side of the reinforcing rib 2, that is, the weight guide structure 4 can be fixed on one side or the other side of the door panel body 1 in the width direction. If the door panel main body 1 is supported by the plurality of reinforcing ribs 2, the excessive middle space of the door panel main body 1 is occupied, and the heavy hammer guide structure 4 cannot be installed.

In the above-mentioned embodiment, elevator layer door panel structure, it includes door plant main part 1, strengthening rib 2, backup pad 3 and weight guide structure 4, and strengthening rib 2 sets up in door plant main part 1 along its width direction's intermediate position, and the equal vertical setting of strengthening rib 2 and backup pad 3. Through setting up backup pad 3 in the width direction both sides of door plant main part 1 in order to replace the strengthening rib 2 that needs extra setting to guarantee the intensity of layer door plant, can not occupy the installation space of weight guide structure 4 like this, can install weight guide structure 4 on the left side or the right side of strengthening rib 2.

In one embodiment of the present invention, referring to fig. 1 and 5, the door main body 1 includes a main door 11, a first bending plate 12 and a second bending plate 13, the number of the first bending plate 12 and the second bending plate 13 is two, one of the first bending plate 12 and the second bending plate 13 is disposed at one long side of the main door 11, and the other of the second bending plate 12 and the second bending plate 13 is disposed at the other long side of the main door 11.

One side of the first bending plate 12 is connected to the long side of the main door panel 11, and the other side of the first bending plate 12 is connected to the second bending plate 13, that is, the first bending plate 12 and the second bending plate 13 are disposed on both sides of the main door panel 11 in the width direction, so that the cross section of the main door panel 11 is C-shaped (fig. 5). Specifically, the method comprises the following steps:

at one of them long limit department of main door plant 11, first bending plate 12 can set up with main door plant 11 is perpendicular, second bending plate 13 can set up with first bending plate 12 is perpendicular, make second bending plate 13 and main door plant 11 parallel arrangement, thereby make door plant main part 1 have certain thickness, strengthening rib 2, backup pad 3 and weight guide structure 4's thickness all can be less than door plant main part 1's thickness, after installing above-mentioned structure, the thickness of layer door plant plate then can not increase. In addition, the strength of the door panel body 1 on the long side thereof is also increased due to the provision of the first and second bending plates 12 and 13.

Optionally, referring to fig. 1 and 5, the supporting plate 3 is disposed between the main door panel 11 and the second bending plate 13, and can support both the main door panel 11 and the second bending plate 13, so as to prevent the second bending plate 13 from being bent and deformed, and to enhance the strength of the door panel main body 1.
