Description

Technical Field

[0001] The utility model belongs to the technical field of outer windshields for rail vehicles, and in particular relates to an outer windshield for rail vehicles. Background Art

[0002] At present, the main form of the outer windshield of my country's high-speed trains is rubber outer windshield, which is mainly imported. The large-scale rubber injection molding technology for producing such rubber products in China is not very mature, and the rubber outer windshields produced have low product qualification rate and high cost. However, the main design direction of the rubber outer windshield is to improve the U-shaped rubber structure or strengthen the rubber structure to improve reliability. This method improves the air tightness and reliability of the rubber outer windshield to a certain extent, but does not solve the service life and fatigue damage of the rubber outer windshield.

[0003] The rubber strips inside the existing rail vehicle outer windshields have a certain service life. When the rubber strips age, it will affect the air tightness of the connection between the rail vehicles. Therefore, the connecting rubber strips need to be replaced. However, the existing rubber strips and the outer windshield frame are an integrated structure, which makes replacement more troublesome. Most of them are fixed by glue, so that when the aged rubber strips are removed later, there will be a lot of residual glue, which affects the sealing of the new rubber strips. For this reason, we propose an outer windshield for rail vehicles. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4 The utility model provides a technical solution: an outer windshield for a rail vehicle, comprising an outer windshield main body 1, a quick replacement mechanism is arranged inside the outer windshield main body 1, docking guide mechanisms are arranged on both sides of the outer windshield main body 1, and the quick replacement mechanism comprises: a sealing connection component and a locking component; the sealing connection component is arranged in the end of the outer windshield main body 1; the locking component is arranged on the inner side of the outer windshield main body 1 and connected with the sealing connection component.

[0019] In the present embodiment, preferably, the sealing connection assembly includes an embedded seat 100 opened at the end of the outer windshield body 1 and a frame 101 arranged inside the embedded seat 100, a rubber strip 102 is fixed to the end of the frame 101, and a connecting groove 200 and a connecting block 201 symmetrically fixed on one side of the inner wall of the embedded seat 100 and engaged with the connecting groove 200 are symmetrically opened on one side of the frame 101, so that the frame 101 can be accurately connected to the embedded seat 100 when connected.

[0020] In this embodiment, preferably, a guide groove 300 and a guide block 301 fixed inside the connecting groove 200 and engaged with the guide groove 300 are provided at the end of the connecting block 201, and limiting grooves 400 are symmetrically provided on both sides of the guide block 301 and limiting buckles 401 are symmetrically fixed on both sides of the inner wall of the guide groove 300 and engaged with the limiting grooves 400, so that the guide block 301 can be temporarily limited inside the guide groove 300.

[0021] In this embodiment, preferably, the locking assembly includes a positioning hole 500 symmetrically opened on the other side of the frame 101 and a screw hole 501 symmetrically penetrated and opened on the other side of the inner wall of the embedded seat 100, and a positioning screw 502 is provided on the inner side of the outer windshield body 1, which passes through the screw hole 501 and is screwed together with the positioning hole 500, so as to facilitate fixing the frame 101 inside the embedded seat 100.
