Technical Field

[0001] The utility model relates to the field of platform doors, in particular to an assembled door structure of a platform door. Background Art

[0002] Rail transit platform doors are used as a safety barrier to separate the train running area from the platform waiting area, effectively preventing passengers from accidentally falling into the train running area while waiting for the train, and protecting the personal safety of passengers. The platform door structure is mainly composed of sliding doors, fixed doors, emergency doors and end doors. The door bodies are generally made of tempered glass bonded to stainless steel pipe door frames or aluminum alloy profile door frames that can resist crowd squeezing and piston wind pressure loads through structural adhesive.

[0003] Currently, the bonded door structure is limited by the characteristics of the glass adhesive and the process conditions, and cannot meet the requirements of quickly replacing the glass on the platform when the glass is broken. The bonded door structure has the following shortcomings and disadvantages:

[0004] 1. The reliability of bonding is affected by many factors, such as the bonding environment, bonding process, and aging. Many uncontrollable factors increase the risk of the entire glass detaching and injuring people after the glass bonding fails.

[0005] 2. The glass and the frame need to be bonded in a strict constant temperature, constant humidity, and low dust workshop environment, and the adhesive needs to be cured for a long time before it can be moved. This results in low production efficiency and high cost.

[0006] Therefore, it is necessary to develop a new type of platform door assembled door structure to meet the requirements of rapid replacement of glass on the platform site, improve manufacturing efficiency, reduce replacement costs, and improve safety. Utility Model Content

[0007] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides an assembled door structure for platform doors, which meets the requirements of rapid replacement of glass on the platform site, improves manufacturing efficiency, reduces replacement costs, and improves safety.

[0008] Technical solution: The utility model is an assembled door structure for platform doors, which is characterized by: it includes tempered glass, and the metal gussets around the tempered glass are installed on the front surface of the door frame by fixing screws, and the U-shaped groove rubber strips wrapped around the tempered glass and the lower bearing pads limit the tempered glass in the installation groove formed by the metal gussets and the door frame; the rear and inner exposed surfaces of the door frame are covered with decorative panels, and the sides of the door frame are provided with engaging anti-pinch rubber strips.

[0009] Wherein, the metal buckle plate is provided with a plurality of fixing screws.

[0010] Wherein, the top and both sides of the tempered glass are provided with U-shaped groove rubber strips.

[0011] Wherein, the bottom of the tempered glass is provided with a U-shaped groove rubber strip and a lower bearing pad.

[0012] Wherein, the bottom of the tempered glass is provided with a plurality of lower bearing pads below the U-shaped slot rubber strip.

[0013] Wherein, the lower bearing pads are arranged at equal distances.

[0014] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: The utility model solves the problem of quickly replacing the glass on the platform site after the platform door is glazed, and also avoids the risk of glass detachment due to failure of adhesive. The carbon structural steel pipe is wrapped with decorative cladding plates to improve the strength of the door frame structure compared to the existing stainless steel or aluminum profile door frame of the same thickness. The door structure forms an effective buffer and protection for the periphery of the glass, effectively preventing the tempered glass from breaking due to vibration, impact or external force.
