Description

Technical Field

[0001] The invention relates to the technical field of train windshield aluminum profiles, and in particular to a high-strength train windshield aluminum profile. Background Art

[0002] In the field of modern railway transportation, the running speed of trains is constantly increasing, and the performance requirements for various train components are becoming more and more stringent. As a key component connecting train carriages, the performance of train windshields is directly related to the safety, comfort and overall energy efficiency of train operation. Early train windshields were mostly made of ordinary materials, such as some low-strength aluminum alloys or other metal materials. As the speed of trains gradually increases, the disadvantages of these traditional windshield materials are increasingly prominent when facing complex working conditions such as strong airflow impact, body vibration and frequent opening and closing operations generated during high-speed driving. Windshields made of ordinary materials are difficult to withstand the continuous pressure of high-speed airflow, and are prone to deformation and damage. Not only do they affect the normal use of windshields, they may also pose a threat to the safe operation of trains. At the same time, in terms of sound insulation and sealing, traditional materials also perform poorly and cannot effectively block the noise and dust generated by train operation, reducing the passenger experience. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a high-strength train windshield aluminum profile.

[0004] The invention provides a high-strength train windshield aluminum profile, comprising a strip-shaped base plate, a top block and a clamping block. The strip-shaped base plate is placed horizontally, and side plates are vertically connected on both sides thereof. The outer side walls of the two groups of side plates are provided with arc plates protruding outwards, and the cross section of the aluminum profile is an axisymmetric figure.

[0005] A cavity is provided between the side plate and the connected arc plate, and multiple groups of positioning tubes are connected between the arc plate and the corresponding side plate, and the multiple groups of positioning tubes are located in the container and are perpendicular to the side plate;

[0006] The two groups of top blocks are respectively slid vertically on the two groups of side plates, and the inner side surfaces of the two groups of top blocks are both set as inclined surfaces, which are inclined from top to bottom toward the central axis direction of the cross section of the profile;

[0007] The two groups of clamping blocks are vertically located between the two groups of side plates and are respectively slidably connected to the inner side walls of the two groups of top blocks. The outer side surfaces of the two groups of clamping blocks are both set as inclined surfaces, which are inclined from bottom to top toward the central axis direction of the cross section of the profile;

[0008] The inclined surfaces of the two groups of clamping blocks are slidably connected with the corresponding inclined surfaces of the top blocks, and the inclined surfaces of the clamping blocks and the top blocks have the same inclination angle;

[0009] The upper parts of the inclined surfaces of the two groups of clamping blocks are laterally connected with multiple groups of guide rods, and the multiple groups of guide rods correspond to the multiple groups of positioning tubes one by one and are movably sleeved;

[0010] Two groups of bolts are arranged on the strip-shaped base plate, and the two groups of bolts are respectively connected with the bottom threads of the two groups of top blocks. By rotating the bolts, the corresponding top blocks can be controlled to rise and fall.

[0011] Preferably, a plurality of groups of first reinforcing ribs are provided on the top of the strip-shaped substrate and between the side panels on both sides.

[0012] Preferably, multiple groups of first clamping grooves are provided on the bottom sides of the two groups of top blocks, and each group of the first clamping grooves respectively corresponds to and is clamped with the first reinforcing ribs one by one.

[0018] In the present invention, a high-strength train windshield aluminum profile is proposed, in which two clamping plates are used to clamp one side of the glass. The bolt is rotatably connected to the strip base plate through a bearing, and the threaded portion of the bolt is threadably connected to the top block. By rotating the bolt, the top block can be moved in the vertical direction of the side plate.
