[0001] The utility model specifically relates to a special protective dust cover based on a high - speed rail braking system. Background Art
[0002] Train braking refers to artificially stopping the movement of a train, including decelerating it, not accelerating it, or stopping its operation. Releasing or weakening the braking effect on a braked train or locomotive is called "relieving".
[0003] At present, after long - term use, dust and impurities will be generated on the surface of electronic components in the train braking system, which will affect the use of the electronic components and reduce their service life. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a special protective dust cover based on a high - speed rail braking system to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A special protective dust cover based on a high - speed rail braking system, including a dust cover. Two ears extend outward from both sides of the dust cover. A groove is reserved between every two adjacent ears. On the outer side of the dust cover and within two grooves, there are openings. The groove is connected to the internal cavity of the dust cover through the opening. A limiting component for fixing the dust cover is arranged in the groove.
[0006] Preferably, the limiting component includes a rotating shaft arranged in the groove, and both ends of the rotating shaft are inserted into two ears respectively.
[0007] Preferably, a rotatable connecting arm is arranged on the rotating shaft. There are two connecting arms, and the two connecting arms are symmetrically arranged.
[0008] Preferably, one end of the connecting arm facing the opening of the groove is an elliptical part, and the elliptical part abuts against the electronic component in the cavity of the dust cover.
[0009] Preferably, strip - shaped grooves are respectively opened inside the ends where the two connecting arms are close to each other, and positioning bolts are inserted into the strip - shaped grooves.
[0010] Preferably, a limiting nut is arranged on the side of the strip - shaped groove away from the insertion direction of the positioning bolt, and an internal thread adapted to the outer thread of the positioning bolt is opened in the limiting nut.
[0011] Preferably, a handle is arranged at one end of the positioning bolt away from the limiting nut.
[0012] Technical effects and advantages of the present utility model: For the special protective dust cover based on the high-speed rail braking system, through the rotation of the rotating shaft, two connecting arms are driven to rotate in opposite directions, causing the elliptical part to move, so that the part of the elliptical part located inside the cavity of the dust cover moves through the notch towards the groove. At this time, the dust cover can be installed on the surface of the electronic components of the braking system to protect the electronic components. Then rotate the two connecting arms again to make the two connecting arms approach each other until the two strip grooves coincide. Use the positioning bolt to penetrate the strip groove and insert it into the limit nut to complete the fixation of the connecting arm. And when the connecting arms approach each other, the elliptical part rotates and re-enters the cavity to abut against the electronic components, realizing the fixation of the dust cover, which can effectively prevent dust and impurities from entering the electronic components and improve the service life of the electronic components.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.
[0019] To prevent dust from entering the electronic components, refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, it includes a dust cover 1. Two ears 2 extend outward from both sides of the dust cover 1. A groove 3 is reserved between every two adjacent ears 2. On the outer side of the dust cover 1 and within the two grooves 3, there are openings. The groove 3 is connected to the internal cavity of the dust cover 1 through this opening. A limiting component for fixing the dust cover 1 is arranged in the groove 3. By rotating the rotating shaft 4, the two connecting arms 5 are driven to rotate in opposite directions, causing the elliptical part 6 to move. The part of the elliptical part 6 located inside the cavity of the dust cover 1 moves toward the groove 3 through the opening. At this time, the dust cover 1 can be installed on the surface of the electronic component of the braking system to protect the electronic component. Then, rotate the two connecting arms 5 again to make the two connecting arms 5 approach each other until the two strip-shaped grooves 7 coincide. Pass the positioning bolt 8 through the strip-shaped groove 7 and insert it into the limiting nut 9 to complete the fixation of the connecting arm 5. And when the connecting arms 5 approach each other, the elliptical part 6 rotates and re-enters the cavity to abut against the electronic component, realizing the fixation of the dust cover 1. Through the dust cover 1, dust can be prevented from entering the electronic component, and the service life of the electronic component can be extended.
[0020] To improve the stability of the dust cover 1 after installation, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, the limiting component includes a rotating shaft 4 arranged in the groove 3. The two ends of the rotating shaft 4 are respectively inserted into the two ears 2. The rotating shaft 4 is provided with rotatable connecting arms 5. There are two connecting arms 5, and the two connecting arms 5 are symmetrically arranged. When the two connecting arms 5 move away from each other, the elliptical part 6 can be moved out of the cavity of the dust cover 1. At this time, the dust cover 1 can be sleeved on the electronic component. One end of the connecting arm 5 facing the opening of the groove 3 is the elliptical part 6, and the elliptical part 6 abuts against the electronic component in the cavity of the dust cover 1. As the two connecting arms 5 approach each other, the elliptical part 6 rotates and moves toward the cavity, abutting against the electronic component, thereby fixing the dust cover 1 on the electronic component and improving the stability of the dust cover 1 after installation. Inside the ends of the two connecting arms 5 close to each other, there are strip-shaped grooves 7. A positioning bolt 8 is inserted into the strip-shaped groove 7. A limiting nut 9 is arranged on the side of the strip-shaped groove 7 away from the insertion direction of the positioning bolt 8. The limiting nut 9 is provided with internal threads adapted to the external threads of the positioning bolt 8. One end of the positioning bolt 8 away from the limiting nut 9 is provided with a handle 10. By rotating the handle 10, the positioning bolt 8 is driven to rotate. Through the adaptation of the positioning bolt 8 to the internal threads of the limiting nut 9, the positioning bolt 8 is inserted into the limiting nut 9, and the two connecting arms 5 can be fixed together, further fixing the elliptical part 6 and improving the stability of the dust cover 1 fixed on the electronic component.
[0021] During use, first rotate the rotating shaft 4 to drive the two connecting arms 5 to rotate in opposite directions, causing the elliptical portion 6 to move. Move the portion of the elliptical portion 6 located inside the cavity of the dust cover 1 through the notch towards the groove 3. At this time, the dust cover 1 can be installed on the surface of the electronic component of the braking system to protect the electronic component. Then rotate the two connecting arms 5 again to make the two connecting arms 5 approach each other until the two strip-shaped grooves 7 coincide with each other. Pass the positioning bolt 8 through the strip-shaped groove 7 and insert it into the limit nut 9 to complete the fixation of the connecting arm 5. And when the connecting arms 5 approach each other, the elliptical portion 6 rotates and re-enters the cavity to abut against the electronic component.
[0022] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
