Description

Technical Field

[0001] This utility model relates to the field of door systems for urban rail vehicles, and in particular to a roller guide rail structure door system. Background Technology

[0002] The guide rail structure door system is extremely important in the field of urban rail vehicle door system technology. This structure realizes the load-bearing and movement of the door system, directly affecting the safety and movement functions of urban rail vehicle doors. The existing guide rail door system structure, such as patent EP1914372B1, uses a slider mounted on a single guide rail to drive the gantry assembly to realize the load-bearing and movement of the door system. However, this system suffers from problems such as complex slider structure, difficulty in maintenance, and poor durability.

[0003] Therefore, it is necessary to develop a new type of guide rail structure door system to overcome the above problems. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a roller guide rail structure door system, which provides a novel roller-type linear guide rail structure door system. The roller structure can effectively increase the load-bearing capacity, improve durability and wear resistance, while the structure is simple, easy to maintain, and reduces maintenance costs.

[0005] Technical solution: The present invention relates to a roller guide rail structure door system, characterized in that: it includes a linear guide rail, which is connected to the external door leaf through a connecting plate, and the linear guide rail is connected to a load-bearing drive assembly; the linear guide rail includes a mounting base plate, a load-bearing plate, and rollers; the rollers are mounted on the load-bearing plate and are installed in the track of the mounting base plate.

[0006] The door panel mentioned above is located in the door system of urban rail vehicles.

[0007] The linear guide rail is connected to the load-bearing drive assembly via screws.

[0008] The rollers are mounted on the load-bearing plate using mounting screws and locking washers.

[0009] The rollers are mounted on the track of the mounting base plate via roller bodies.

[0010] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention increases the contact area and its own rigidity, which can improve the load-bearing performance of the linear guide; the structure is simple and easy to disassemble and maintain; and the durability is better, which improves the service life of the linear guide.

[0012] Figure 2 This is a schematic diagram of the structure of the present invention in its closed state;

[0013] Figure 3 This is a schematic diagram of the cross-sectional structure of the present invention;

[0014] In the figure, 1 is the load-bearing drive assembly; 2 is the connecting plate; 3 is the linear guide rail; 31 is the mounting base plate; 32 is the load-bearing plate; 33 is the roller; 331 is the roller body; 332 is the mounting screw; and 333 is the locking washer. Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] The roller guide rail structure door system of this utility model includes a linear guide rail 3, which is connected to the external door leaf through a connecting plate 2 and is connected to a load-bearing drive assembly 1. The linear guide rail 3 includes a mounting base plate 31, a load-bearing plate 32 and rollers 33. The rollers 33 are mounted on the load-bearing plate 32 and are installed in the track of the mounting base plate 31.

[0017] The door leaf of this utility model is located in the door system of an urban rail vehicle. The linear guide rail 3 is connected to the load-bearing drive assembly 1 by screws. The roller 33 is mounted on the load-bearing plate 32 by mounting screws 332 and locking washers 333. The roller 33 is mounted in the track of the mounting base plate 31 by roller body 331.

[0018] When in use, the door leaf is connected to the connecting plate 2 to realize the load-bearing and movement functions of the door.

[0019] like Figure 1 and Figure 2 As shown, when the load-bearing plate 32 moves with the load-bearing drive assembly 1, the mounting base plate 31 track will come into contact with the roller 33. The roller 33 has a larger contact surface with the mounting base plate 31 and the roller itself has better rigidity, which can improve the load-bearing performance of the linear guide rail. At the same time, it ensures the movement trajectory of itself and the load-bearing plate 32 so that the door can achieve the correct movement direction and realize the opening of the door, which can ensure the complete movement of the door.

[0020] This invention increases the contact area and its own rigidity, which can improve the load-bearing capacity of the linear guide; its simple structure makes it easy to disassemble and maintain; and its better durability improves the service life of the linear guide.
