[0002] Rail transit refers to a type of transportation vehicle or transportation system that requires operating vehicles to travel on specific tracks. The most typical rail transit is the railway system composed of traditional trains and standard railways. With the diversified development of train and railway technologies, rail transit presents more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. When the rail transit vehicle body is in use, large vibrations and noises are likely to occur. Therefore, we need an adjustable shock absorber and noise reducer for the rail transit vehicle body.
[0003] However, when the existing rail transit shock absorbers are used outdoors, there is a lot of dust, and the dust is likely to accumulate inside the shock absorbers, resulting in a reduction in the shock absorption effect and affecting the use effect.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a rail transit shock absorber provided with a dust-proof component is provided. Content of the Utility Model

The protection component includes an outer protection bag, an outer protection rod, a mounting hole, a mounting pipe and a pressure sensor. The outer protection rod is arranged outside the outer protection bag, and mounting holes are opened on the surface of the outer protection rod. A mounting pipe is arranged inside the mounting hole, and a pressure sensor is installed inside the mounting pipe.
[0007] Further, the shape of the outer protection rod is arc-shaped, and twelve outer protection rods are arranged in a circular distribution about the center point of the outer protection bag.
[0008] Further, fixing holes are opened on the side of the bottom mounting plate, and a gasket is connected to the lower end of the bottom mounting plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0022] As Figure 1 and Figure 2 shown, a rail transit shock absorber provided with a dust-proof component includes a bottom mounting plate 1 and a protection component 3. The upper end of the bottom mounting plate 1 is connected with an outer frame 2. The protection component 3 for dust-proof is arranged on the outside of the outer frame 2. The protection component 3 includes an outer protection bag 301, an outer protection rod 302, a mounting hole 303, a mounting pipe 304 and a pressure sensor 305. An outer protection rod 302 is arranged outside the outer protection bag 301. The outer protection bag 301 plays an outer covering role at the connection position of the outer frame 2 and the inner frame 8, preventing dust from entering the shock absorber and causing dust accumulation, which affects the shock absorption effect. The shape of the outer protection rod 302 is arc-shaped, and twelve outer protection rods 302 are arranged in a circular distribution about the center point of the outer protection bag 301. The outer protection rod 302 plays an outer protection role outside the outer protection bag 301, and mounting holes 303 are formed on the surface of the outer protection rod 302. A mounting pipe 304 is arranged inside the mounting hole 303, and a pressure sensor 305 is installed inside the mounting pipe 304. The pressure sensor 305 monitors the pressure inside the outer protection bag 301, so as to detect in time when the outer protection bag 301 is damaged or the pressure value is abnormal, and then maintain the outer protection bag 301 in time. A fixing hole 4 is formed on the side of the bottom mounting plate 1, and a gasket 5 is connected to the lower end of the bottom mounting plate 1. The upper end of the outer protection rod 302 is connected with a top plate 6, and a connecting rod 7 is arranged in the middle of the top plate 6.
[0023] As Figure 3 shown, the lower end of the top plate 6 is connected with an inner frame 8, and the inner frame 8 and the outer frame 2 are sleeved and connected. A limiting component 9 for active limiting is arranged on the outer surface of the inner frame 8, and the number of the limiting components 9 is set to four groups. The limiting component 9 includes a limiting groove 901 and a limiting block 902, and the limiting block 902 is slidably installed inside the limiting groove 901. The limiting block 902 slides in the limiting groove 901, making the movement of the inner frame 8 relative to the outer frame 2 more stable under the action of the shock absorption spring 10, and preventing the shaking of the inner frame 8 from affecting the shock absorption effect. A shock absorption spring 10 is arranged inside the inner frame 8, and a movable rod 11 is arranged in the middle of the shock absorption spring 10. The two shock absorption springs 10 and the movable rod 11 play a role in shock absorption for the vibration in rail transit.
[0024] In summary, for the rail transit shock absorber provided with a dust-proof component, first, according to Figures 1 - 3In the structure shown, bolts are used to connect the bottom mounting plate 1, the connecting rod 7 and the track damping position respectively. After the top plate 6 and the inner frame 8 receive vibration, while being damped by the damping spring 10, the inner frame 8 makes corresponding position movements in the outer frame 2. When moving, the limiting block 902 slides in the limiting groove 901, making the movement of the inner frame 8 relative to the outer frame 2 more stable under the action of the damping spring 10, and avoiding the shaking of the inner frame 8 from affecting the damping effect. When in use, the outer protective bladder 301 directly plays a dust-proof role at the connection position of the outer frame 2 and the inner frame 8, preventing dust from entering the shock absorber and causing dust accumulation to affect the damping effect. At the same time, a certain amount of gas can be filled into the outer frame 2 and the inner frame 8, so that the outer protective bladder 301 can also play a damping role during damping. At the same time, the pressure sensor 305 monitors the internal pressure of the outer protective bladder 301, so as to detect in time when the outer protective bladder 301 is damaged or the pressure value is abnormal, and thus carry out timely maintenance on the outer protective bladder 301.
