the two end sockets 13 are respectively wrapped and fixed on the top side 121 and the bottom side 122 of the door panel;

and one end of each framework 14 is positioned in the corresponding seal head 13 and is fixed with the door panel 12, the other end of each framework 14 extends out of the seal head 13 and is fixed on the support column 11, and the part of each framework 14 adjacent to the support column 11 is used as a door shaft adapting part 141.

The door leaf 1 serves as a main part of the elevator door, and plays a role in isolating the inside and the outside of the elevator vertical hinged door, so that certain strength is required. The establishment of the isolation can be switched by the rotation of the door leaf 1, in this embodiment, the axis of the rotation of the door leaf 1 is the supporting column 11, in the above components, the supporting column 11 and the two frameworks 14 form a main stressed frame, and the door panel 12 realizes the structural stability through the stressed frame. Of course, the door panel 12 itself needs a certain strength to maintain the function of isolating the inside and outside of the elevator side hung door. The framework 14 is fixed to the support column 11 at one end and extends substantially in the radial direction of the support column 11 at the other end, thereby achieving stable movement of the door panel 12.

In the specific arrangement of the supporting column 11, in an embodiment, the supporting column 11 includes an upright column 112 and two corner pieces 113 installed at two ends of the upright column 112, and the upright column 112 and the two corner pieces 113 are an integral or separate structure; the two frames 14 extend in the width direction of the door panel 12 and are fixed to corner pieces 113 at corresponding positions, respectively.

The supporting columns 11 function to transmit the force of the door leaf 1 to the upper and lower door shafts. The design of the corner member 113 improves the connection effect of the frame 14, and provides a better corner appearance, facilitating tolerance release during assembly. The corner member 113 and the upright post 112 are advantageously separate from each other and integrated, and can be adjusted according to the specific use situation. For example, when the upright column 112 and the two corner pieces 113 are integrated, the overall strength of the supporting column 11 is better, and at the same time, the limitation is less during modeling design, the overall adaptability is stronger, and the use requirements of different scenes can be met. For example, when the upright post 112 and the two corner pieces 113 are separated, the upright post 112 and the corner can be designed respectively, the upright post 112 is made of sectional materials, the strength, the assembly degree and the economy of the upright post are excellent, the corner can be adjusted according to needs according to different products, and the rapid response is convenient to be carried out according to market environments with various requirements.

The door panel 12 is stressed, except for the installation groove 111 on the support column 11, and stress connection is mainly realized through the framework 14. In one embodiment, each of the armatures 14 includes:

the vertical extending part 142 is fixedly attached to the surface of the door panel 12;

the lateral extension 143 is bent horizontally from the vertical extension 142 in a direction away from the panel surface of the door panel 12.

The vertical extension 142, which is flush with the face of the panel 12, enables an effective connection of the armature 14 and the panel 12. The attached arrangement can provide a larger contact area, so that the stress performance is improved. The first transverse extension part 143 can function as a reinforcing rib, so that the framework 14 forms an angle iron form, and the mechanical property of the door panel 12 is improved under the condition of certain length, material and other parameters; secondly, can realize the bearing to head 13, make things convenient for the installation of electrical apparatus part.

In the connection between the frame 14 and the corner, in an embodiment, a slot 1131 is formed on a side of each corner member 113 facing the door panel 12, one end of each frame 14 extends into the slot 1131 of the corresponding corner, and a reinforcing plate 144 is further fixed on the top surface of the portion extending into the slot 1131.

When the door panel 12 is stressed, stress concentration is easy to occur at the joint of the framework 14 and the corner piece 113, and the reinforcing plate 144 is designed to strengthen the area, so that the situation of connection failure caused by material fatigue and the like after long-term use is avoided. The reinforcing plate 144 is connected to the frame 14 by fasteners, and is engaged with the corner member 113 through the engaging groove 1131 to reinforce the corner member. The reinforcing plate 144 is designed separately to compensate for the tolerance between the parts, thereby facilitating assembly.
