Technical Field

[0006] , ,

[0005] ,

[0001] The utility model relates to the technical field of elevator door production, and particularly relates to an elevator door with a reinforcing rib positioning structure. Background Art

[0002] In the structural design of elevator door panels, in order to improve the overall rigidity and anti-deformation ability of the door panels, multiple bends are usually made on the four sides of the panel to enhance the edge strength, and a reinforcing rib structure is arranged in the middle of the panel. In the prior art, the reinforcing ribs usually adopt a U-shaped or "ji" - shaped structure, and their two side edges are attached to the panel and fixed by spot welding to improve the bending resistance and impact resistance of the door panel.

[0003] However, the existing reinforcing rib welding process has the following problems: the reinforcing ribs need to be placed at the designated positions on the panel by workers. Specifically, workers need to measure the distance between the reinforcing ribs and the four - side edges of the panel, adjust the positions to determine their positions at the designated positions. The positioning process is time - consuming and prone to deviation. After positioning, workers need to press the reinforcing ribs to prevent them from moving and then perform spot welding, with low efficiency and high labor intensity. Content of the Utility Model

[0004] The utility model provides an elevator door with a reinforcing rib positioning structure to facilitate the positioning and fixing of the reinforcing ribs in the production of elevator doors.

[0005] The utility model discloses an elevator door with a reinforcing rib positioning structure, which includes a panel. Bending parts are arranged on the four sides of the panel. The bending parts are bent 90° three times towards one side of the panel to form an edge structure. The edge structure is U - shaped towards the panel. Slots are arranged in the middle of the opposite side surfaces of two opposite edge structures. An opening is arranged upwards on the edge structure on one side of the slot, and the opening is communicated with one side of the slot. The end of the slot far away from the opening is lower than the end of the slot communicating with the opening. It further includes a reinforcing rib. The cross - section of the reinforcing rib is "ji" - shaped. Plate bodies extend outwards along the length direction of the upper sides of both ends of the reinforcing rib. The plate bodies are inclined, and the inclination direction and degree of the plate bodies match the slot. The plate bodies are stuck in the slots, and the lower side of the reinforcing rib is pressed against the panel.

[0006] The above technical solution forms an edge structure by bending the bending parts on the four sides of the panel 90° three times, and arranges inclined slots and openings on two opposite edge structures. The reinforcing rib adopts a "ji" - shaped cross - section, and inclined plate bodies matching the slots extend from both ends. During installation, the inclined plate bodies of the reinforcing rib are pressed in from above through the openings, slide into the slots along the slots and are clamped tightly. At the same time, the lower side of the reinforcing rib naturally adheres to the panel, realizing rapid positioning and automatic pressing, and subsequent spot welding can be carried out without manual adjustment. The inclined design of the slot, that is, the end far away from the opening is lower, enables the reinforcing rib to gradually press the panel during the sliding process, ensuring the degree of fit.

[0007] The end of the slot furthest from the opening is 1 to 3 millimeters lower than the end of the slot connected to the opening. Too small a drop will result in insufficient clamping force, while too large a drop will result in increased clamping resistance or deformation of the plate. A moderate drop of 1 to 3 millimeters balances the sliding resistance and positioning accuracy.

[0008] The elevator door with a reinforcing rib positioning structure obtained by this utility model has the following advantages: the reinforcing rib is automatically guided and clamped by the cooperation of the slot and the inclined plate, which eliminates the manual positioning step and improves the assembly efficiency. The inclined structure of the slot makes the reinforcing rib press down naturally when it slides in, ensuring a tight fit with the panel. Attached Figure Description

[0017] like Figures 1 to 6As shown in the figure, the utility model discloses an elevator door with a reinforcing rib positioning structure, which includes a panel 1. Bending parts are arranged on the four sides of the panel 1. The bending parts are bent 90° three times towards one side of the panel 1 to form an edge structure 2. The edge structure 2 is U-shaped facing the panel. A clamping groove 3 is arranged in the middle of the opposite side surfaces of two opposite edge structures 2. An opening 4 is arranged upwards on the edge structure 2 on one side of the clamping groove 3. The opening 4 is communicated with one side of the clamping groove 3. The end of the clamping groove 3 far away from the opening 4 is 2 mm lower than the end of the clamping groove 3 communicated with the opening 4. It further includes a reinforcing rib 5. The cross-section of the reinforcing rib 5 is in a "ji" shape. Plate bodies 6 extend outwards along the length direction of the upper sides of both ends of the reinforcing rib 5. The plate bodies 6 are inclined, and the inclination direction and degree of the plate bodies 6 match the clamping groove 3. The plate bodies 6 are clamped in the clamping groove 3. The lower side of the reinforcing rib 5 presses against the panel 1.
