Description

Technical Field

[0001] This utility model belongs to the field of elevator door technology, and in particular relates to a concealed elevator door with quick door panel replacement. Background Technology

[0002] Existing swing doors in home elevators present several pain points: Door panel decorations are difficult to replace. Current door panels are mostly made of solid steel or stainless steel, with surface decorations fixed by adhesives, welding, or riveting. This makes it impossible to quickly replace personalized decorations or advertising images without removing the door operator or stopping the elevator, resulting in long maintenance cycles and high costs. The door operator and door panel have a heavy visual appearance, making it difficult to coordinate with interior design styles. Some replacement solutions have low safety levels. Simple detachable methods such as using magnets or Velcro are ineffective in terms of scratch resistance, moisture resistance, and fire resistance, and are prone to bulging and warping. Furthermore, the replacement process is complex and may require repositioning. In addition, adding decorations to the existing door operator will increase the load on the moving parts, reduce the door operator's lifespan, and increase abnormal noises. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of the difficulty in replacing the decoration of elevator door panels, the inability to quickly replace personalized decorations or advertising images without removing the door machine or stopping the elevator, the long maintenance cycle and high cost, and the complexity of the replacement process or the need for repositioning, which increases the maintenance cost. Therefore, this utility model proposes a hidden elevator door with quick door panel replacement.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a concealed elevator door with quick door panel replacement, comprising:

[0005] The door frame is connected to the elevator exit. The door panel is equipped with a door pivot column, which is installed on the door frame by hinges. An electric door closer is installed between the top of the door frame and the door panel.

[0006] Several tensioning column bodies are installed on the door pivot column;

[0007] The door lock is installed on the door frame and has a door ball.

[0008] Furthermore, a safety contact is provided on the aforementioned door panel, which passes through the door frame and is connected to the door lock.

[0009] Furthermore, the aforementioned tensioning column body is provided with a push block and a stop block, a first spring is provided between the push block and the stop block, a lock tongue is installed inside the door panel, a second spring is provided at the top of the lock tongue, and a column tail slider is provided at the tail of the tensioning column body.

[0010] Furthermore, a lock tongue groove is pre-embedded in the aforementioned door panel, and the tensioning column body and the lock tongue are located within the lock tongue groove.

[0011] Furthermore, the aforementioned stop block and push block are mushroom-shaped, arranged opposite to each other, with the bottom of the locking tongue facing the push block in an arc shape.

[0012] Furthermore, the tensioning column body is connected to the door pivot column by screwing several studs onto the column tail slider. The studs are located at the upper and lower ends and the middle position of the column tail slider, respectively, with the middle stud and the tensioning column body on the same horizontal line.

[0013] This utility model provides a concealed elevator door with quick door panel replacement. The installation position of the door pivot column is pre-defined during door panel manufacturing, and the latch, second spring, and latch groove are already installed inside the door. The number and position of the latch, second spring, and latch groove can be adjusted according to actual conditions to ensure the door panel's secure installation. During installation, the door pivot column is first installed to the door frame via hinges, then the column tail slider, tension column body, stop block, and first spring 1 assembly are installed. Finally, the door panel is directly inserted horizontally into the door pivot column until the latch groove is engaged. After the latch is engaged, tighten the two studs on the tail slider. Finally, install the electric door closer and adjust the door panel position. In this structure, the mushroom-shaped head at the front of the tensioning column body pushes up the latch in the latch groove when inserted. After completion, the mushroom-shaped head at the front of the tensioning column body hooks the latch. Tighten the two studs on the tail slider to increase the tension. When removing the door panel, loosen the two studs on the tail slider and push the tensioning column body forward. The inverted mushroom head of the stop block installed on the tensioning column body will push up the latch and hook it. At this point, the door panel can be pulled out for replacement.

[0014] Therefore, this embodiment has the following advantages compared to the prior art:

[0015] 1. The door panel adopts a horizontal plug-in + lock tongue sliding structure. Loosen the column tail slider and push forward to tighten the column to pull out the entire door within 1 minute; the pivot column does not need to be disassembled and the opening position of the entire door does not need to be readjusted and checked; after replacing the decoration or advertising screen, it can be reinserted to complete the installation. The whole process takes 1 person 10 minutes.

[0016] 2. The invisible visual form blends seamlessly with the interior style; the door hinge pillars and locking components are all hidden in the door panel cavity, with only a narrow gap visible on the outside. The door machine beam is naturally concealed by the ceiling, achieving a minimalist "frameless" facade; users can change the door panels to different materials / colors to match the interior decoration, creating a unified style.

[0017] 3. The connection is tight and has a high strength rating; the lock tongue and slide are pre-embedded in the door, and the tension post is directly connected to the metal parts, eliminating the need for low-strength fasteners such as magnets, glue, and self-tapping screws.

[0018] 4. No increase in door operator load, quiet and long lifespan; replacement component weight <250 g, overall door panel weight increase <5%, door operator power does not need to be recalibrated; no loose gap after tightening, operating noise ≤45 dB(A), 8 dB lower than traditional detachable solutions, door operator lifespan extended ≥20%.

[0019] 5. One-button emergency response and dual door opening: The electric door knife strikes the door ball to achieve automatic door opening at the floor level; in case of malfunction, rescuers can manually move the door ball to unlock immediately, combining daily automatic and emergency manual operation to improve the efficiency of escaping trapped personnel. For specific structure, please refer to the company's existing patent CN204369384U, "An Elevator Door Lock Device".

[0020] 6. Modular design results in low cost; the latch, slide, and tensioning post are all standard machined parts, and the door panel is a conventional solid density door panel, with low dimensional requirements, making manufacturing convenient, quick, and cost-effective.
