Description

Technical Field

[0001] This utility model relates to the field of rail vehicle interior design, specifically to a rail vehicle door pillar structure. Background Technology

[0002] The door pillar structure of a rail vehicle is an important structural component inside the vehicle, generally located on both sides of the sliding door. Existing door pillar structures are complex and relatively simple, with small inspection ports and small inspection doors, resulting in limited operating space for maintenance, complicated operations, and affecting the overall aesthetics of the product. Summary of the Invention

[0003] To solve the above technical problems, this utility model provides a rail vehicle door column structure that is simple in structure, has a large maintenance space, and high production efficiency.

[0004] The rail vehicle door pillar structure of this utility model includes: a door pillar main body, a door pillar secondary body, a handrail, a rotary lock, a rotary bearing, and a mounting transition plate; the door pillar main body is fixedly installed on the vehicle body and has an opening along its height, and the door pillar secondary body is located at the opening; the handrail is fixedly connected to the door pillar main body along its height; the handrail is provided with a rotary bearing, and the door pillar secondary body is provided with a mounting transition plate, and the rotary bearing is fixedly connected to the mounting transition plate; the door pillar secondary body is provided with a rotary lock, and the corresponding door pillar main body is provided with a lock slot that matches the rotary lock.

[0005] Furthermore, the handrail is located on the side of the rotary bearing. The rotary bearing is limited by a limiting block to adjust the rotation angle.

[0006] Furthermore, the limiting block and the rotary bearing are provided with matching stepped notches along the circumferential direction. When the notch of the rotary bearing rotates to mate with the notch of the limiting block, it serves to limit the rotation of the rotary bearing.

[0007] Furthermore, the mounting transition plate is angular.

[0008] Furthermore, the two end faces of the installation transition plate are fixedly connected to the rotary bearing and the main body of the door column by bolts.

[0009] Furthermore, the top and bottom of the door post secondary body are provided with rotary locks.

[0010] The rail vehicle door pillar structure described in this utility model has a fixed main body and a secondary body that uses a handrail as a rotation axis and is locked to the main body via a rotary lock. This eliminates the need for a separate inspection port, as the secondary body can be rotated open as a whole, increasing the maintenance space. The structure is simple and beautiful, with high production efficiency, low cost, and easy to popularize and promote. Attached Figure Description

[0017] The following is combined Figures 1 to 4 The rail vehicle door column structure described in this utility model will be described in detail.

[0018] like Figure 1 As shown, the rail vehicle door pillar structure of this utility model includes a door pillar main body 1, a door pillar secondary body 2, a handrail 3, a rotary lock 4, a rotary bearing 5, and an installation transition plate 7.

[0019] The main body 1 of the door pillar is fixedly mounted on the vehicle body. The main body 1 of the door pillar has an opening along its height, such as... Figure 4 As shown, the secondary body 2 of the door pillar is located at the opening, thereby dividing the door pillar into a left and right split structure of the main body 1 and the secondary body 2 of the door pillar, wherein the secondary body 2 of the door pillar can rotate along the main body 1 of the door pillar.

[0020] like Figure 1 As shown, the handrail 3 is installed on the door post body 1 along the height direction, and the top and bottom ends of the handrail 3 are fixedly connected to the door post 1.

[0021] like Figure 1 and Figure 2 As shown, the handrail 3 is equipped with a rotary bearing 5. The rotary bearing 5 is fixedly connected to the door post secondary body 2 through the installation transition plate 7. The installation transition plate 7 is angular, and its two end faces are fixedly connected to the rotary bearing 5 and the door post main body 1 respectively through bolts 8. Thus, the door post secondary body 2 can rotate around the handrail 3 through the rotary bearing 5.

[0022] The top and bottom of the door post secondary body 2 are respectively provided with rotary locks 4, and the corresponding door post main body 1 is provided with a lock hole that matches the rotary lock 4. The door post secondary body 2 is opened and closed by rotating the lock 4.

[0023] The handrail 3 is fitted with a limiting block 6 on one side of the rotary bearing 5. The limiting block 6 and the rotary bearing 5 are provided with matching stepped notches along the circumferential direction, such as... Figure 3 As shown. When the notch of the rotating bearing 5 rotates to engage with the notch of the limiting block 6, the limiting block 6 limits the rotation of the rotating bearing 5, thereby adjusting the rotation angle of the door post secondary body 2.

[0024] The rail vehicle door pillar structure described in this utility model has a fixed main body and a secondary body that uses a handrail as a rotation axis and is locked to the main body via a rotary lock. This eliminates the need for a separate inspection port, as the secondary body can be rotated open as a whole, increasing the maintenance space. The structure is simple and beautiful, with high production efficiency, low cost, and easy to popularize and promote.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
