Abstract

The application relates to a sliding door system of an urban rail train. The system comprises: the door frame is fastened on the door upright post through the nuts and the bolts. The method can improve the installation efficiency, has high precision and is convenient and fast to maintain.

Description

Urban rail train sliding door system

Technical Field

The application relates to the technical field of vehicle equipment, in particular to a sliding door system of an urban rail train.

Background

Urban rail trains have become one of the important transportation means for public travel, and the demand of train sliding door systems is increasing.

In the prior art, a door frame of a train system is an aluminum alloy tensile section, the section of the section is a common L type, a door upright post for installing the door frame is an aluminum alloy tensile section, and the section of the section is a common mouth-shaped cavity section.

The door frame mounting structure has the following disadvantages: aluminum alloy is softer than steel, so aluminum threads cannot meet the installation requirements of equipment; therefore, in order to install other equipment on the aluminum alloy vehicle body, a stainless steel screwed joint or a rivet nut needs to be embedded on the aluminum alloy vehicle body; when the stainless steel threaded joint is embedded, firstly drilling a hole on the aluminum alloy door upright post, then embedding the threaded joint, and finally fastening a bolt; the installation process is complex, the workload is extremely high, and the efficiency is low; the threaded joint falls off, causing major potential safety hazards.

SUMMERY OF THE UTILITY MODEL

In view of the above, it is necessary to provide a sliding door system for an urban rail train, which can improve installation efficiency, has high precision and is convenient to maintain.

An urban rail train sliding door system, the system comprising:

the door frame is fastened on the door upright post through the nuts and the bolts.

In one embodiment, the door pillar is provided with a sliding groove, so that the position of the door frame on the door pillar can be adjusted.

In one embodiment, the door frame is provided with a flange which can cover the sliding groove.

In one embodiment, the nut is a hex nut.

In one embodiment, the bolt is a hex bolt or a T-bolt.

Above-mentioned urban rail train sliding door system, the system includes: the door frame is fastened on the door upright post through the nuts and the bolts. Through the structure, the installation efficiency can be improved, the precision is high, and the maintenance is convenient.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1 and 2, an urban rail train sliding door system comprises:

the door frame comprises a door frame 1, a door upright post 2, a nut 3 and a bolt 4, wherein the door frame 1 is fastened on the door upright post 2 through the nut 3 and the bolt 4.

Because the door frame 1 is fastened on the door upright post 2 by using the structure of the bolt 4 and the nut 3, the door frame can be randomly disassembled and assembled during later-period replacement and maintenance. Meanwhile, as the threaded joint is not used, the situation that the vehicle body cannot be repaired due to the fact that the threaded joint is dropped and the thread is slippery which often happens on the aluminum alloy vehicle body is avoided.

Referring to fig. 3 and 4, the door pillar 2 is provided with a sliding groove for mounting the door frame 1 and the bolt 4. The door upright post 2 is provided with a sliding groove 5, so that the position of the door frame 1 on the door upright post 2 can be adjusted.

The sliding groove 5 arranged on the door upright post 2 can be formed by using an aluminum alloy extruded section; the circular hole does not need to be drilled on the door upright post 2 in the existing turning way, and the threaded joint does not need to be installed on the door upright post 2, so that the production efficiency is obviously improved.

Due to the adoption of the installation mode of the sliding grooves 5, the position of the door frame 1 can be adjusted in the height direction or the width direction during installation, so that the requirement on the installation precision is not high, and the production efficiency is further improved.

Referring to fig. 5 and 6, a flange 6 is arranged on the door frame 1, the length of the flange 6 is X (the X value is set according to the requirement, and is not limited here), and the sliding groove 5 can be covered to ensure the beauty. The installation surface of the door frame 1 moves inwards for a certain distance to cover the sliding groove 5, so that the door frame is more attractive.

In addition, the door frame 1 is provided with a mounting hole 7.

Referring to fig. 7 and 8, the bolt 4 is a hexagon bolt or a T-shaped bolt, wherein the diameter M of the thread 8 is not particularly limited, and the value of M is set as required.

The nut 3 is a hexagonal nut.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
