Problems solved by technology

[0004] The inventor found that this method has the following disadvantages: U-shaped gaskets are difficult to fill, the space is narrow, and the gap has an inclined angle, which requires high skill level of workers. The minimum thickness of the U-shaped gasket is 0.5mm, and the maximum gap after filling can also be Up to 0.5mm, which makes there is a hidden danger of gaps during filling, causing the glass to be distorted by the force of fastening, increasing the risk of glass breakage

Embodiment 1

[0038] In a typical embodiment of the present invention, such as figure 1 As shown, a self-locking threaded connection structure is proposed, which includes a connecting body 1 having a central through hole 2 and a thread 3 on the outer wall of the connecting body 1 .

[0039] In order to facilitate the connection between the threaded connection structure and the front window of the EMU and the car body, the connecting body 1 adopts a cylindrical structure with a certain length. In this embodiment, the connecting body 1 is set as a cylinder, which can ensure that the threaded connection structure and the EMU Convenience when connecting front window and car body.

[0040] The thread 3 is set on the outer wall of the connecting body 1 cylindrical structure throughout, so as to ensure that the threaded connection structure can be reliably connected with the outer frame of the window glass of the EMU; in this embodiment, the outer wall of the connecting body 1 is provided with an ...

Embodiment 2

[0062] In this embodiment, a rail vehicle window installation structure is provided, such as Figure 7 Shown, comprise car window glass outer frame 9, and car window glass outer frame 9 is provided with threaded connection hole, and above-mentioned threaded connection structure penetrates in its threaded connection hole, connects main body 1 outer wall and car window glass outer frame 9 The threaded connection hole is threaded, the self-locking structure 5 of the connecting body 1 is in contact with the car body 10, the central through hole 2 of the connecting body 1 is pierced with a fastening connector 11, and the fastening connector 11 is set with the car body 10. The connecting holes are fastened and connected, thereby realizing the connection of the outer frame of the rail vehicle window glass, the threaded connection structure, and the car body. The installation is convenient, and the gap difference caused by the adjusting gasket in the prior art is avoided, and the glass...

Embodiment 3

[0064] This embodiment provides a rail vehicle, including the vehicle window installation structure as described in Embodiment 2. The arrangement of the above-mentioned vehicle window installation structure makes the installation of the rail vehicle window more convenient, and the safety of the installed glass is higher.

Abstract

The invention discloses a self-locking threaded connection structure, a vehicle window installation structure, a rail vehicle and a method. The self-locking threaded connection structure comprises a connection main body with a central through hole, and the outer side wall of the connection main body is provided with threads; a self-locking structure is arranged at the first end of the connecting main body and comprises a plurality of self-locking blocks, each self-locking block is provided with an outer surface, each outer surface comprises a first face and a second face which are connected with the end face of the connecting main body, the first faces and the second faces are connected in an intersecting mode, and the second faces are inclined faces.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle window installation, and in particular relates to a self-locking threaded connection structure, a vehicle window installation structure, a rail vehicle and a method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] During the installation process of rail vehicle (such as EMU) front window glass, in order to ensure the sealant gap and relative position size, the glass needs to be supported on the car body, and the corresponding fixed points on the car body have supports. At the same time, to ensure the installation in place , the fastening force is uniform, and the glass distortion is reduced. It is necessary to fill U-shaped gaskets in the surrounding 24 fixed positions. After filling, tighten the bolts to meet the requirements. [0004] The inventor found that this...
