Description

Technical Field

[0001] The utility model relates to the field of rail transit doors, in particular to a door frame structure with a single-opening door that is fully closed. Background Art

[0002] The traditional single-door door frame device for rail vehicles is only used for closing cushioning. It is only installed with cushioning strips but no finger guard strips, which poses a safety risk.

[0003] Therefore, it is necessary to develop a new type of single-door closed door frame structure to improve safety. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides a door frame structure for a single door that is closed in place, which effectively prevents fingers from being squeezed during the door closing process, and the door leaf moves stably after being impacted, with high safety.

[0005] Technical solution: The utility model is a door frame structure with a single door that is closed in place, characterized in that it includes a door frame assembly and a door leaf that are connected to each other, the door frame assembly includes a door frame, a buffer rubber strip and a finger guard expansion strip; the buffer rubber strip is located at the front of the door frame; the finger guard expansion strip is located on the inner sides of both sides of the door frame.

[0006] Wherein, the front part and both sides of the door frame are provided with rubber strip installation grooves.

[0007] Wherein, the buffer rubber strip is installed in the installation groove in the middle of the door frame.

[0008] Wherein, the finger guard expansion strip is installed in the installation groove on the side of the door frame.

[0009] Wherein, the door frame assembly is a C-shaped structure.

[0010] Beneficial effect: Compared with the prior art, the utility model has the following significant advantages: the door frame structure of the utility model is used for single-opening sliding doors. After the door leaf is closed, the rubber strip at the front of the door frame is a buffer strip to buffer the impact when it is in place. At the same time, finger protection strips are installed on the side of the door frame to prevent fingers from being squeezed during closing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the structure of the utility model;

[0012] Figure 2 It is a structural schematic diagram of a door frame assembly of the utility model;

[0013] In the figure, 1 is a door frame assembly; 2 is a door leaf; 101 is a door frame; 102 is a buffer rubber strip; and 103 is a finger guard expansion strip. DETAILED DESCRIPTION

[0014] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0015] The single-door closed door frame structure of the utility model comprises a door frame component 1 and a door leaf 2;

[0016] The door frame assembly 1 comprises a door frame 101, a buffer rubber strip 102, and a finger protection rubber strip 103;

[0017] A buffer rubber strip is installed at the front of the door leaf 2;

[0018] Door frame 101 is the main structure of the door frame assembly, which is a high-performance extruded profile; the front end and both sides contain rubber strip installation grooves, which are extruded and formed in one go; the buffer rubber strip and finger guard rubber strip are installed in the door frame slot for easy disassembly;

[0019] The buffer rubber strip 102 is installed in the middle slot of the door frame 101, and can play a buffering role when the door leaf is closed;

[0020] The finger protection rubber strip 102 is installed in the side slot of the door frame 101 to prevent fingers from being squeezed when the door leaf is closed;

[0021] The door frame assembly 1 adopts a C-shaped structure; a rubber strip is installed at the front of the door leaf. After the door leaf is fully closed, the front stop part of the door leaf will enter the C-shaped structure, which can effectively prevent the door leaf from falling out of the moving guide rail after being impacted;

[0022] After the door leaf 2 moves to the door frame assembly 1, the door leaf buffer rubber strip contacts the door frame buffer rubber strip 101, playing a role in buffering the impact of closing the door.

[0023] The utility model discloses a fully closed door frame device for a single-opening sliding door of an urban rail vehicle, which is safe, reliable, easy to implement and has good application prospects.
