[0002] As an important technical basic work for railway transportation safety and management, railway standardization plays an increasingly important role in promoting the technological progress of the railway industry and improving the technical equipment and service quality level. The standards and designs of train dust-proof plugs and chains are aimed at providing effective protection against the entry of external dust, sand and other impurities into the internal systems of locomotives and vehicles. These dust-proof measures are particularly important for protecting the key mechanical and electrical components of the vehicles, because tiny particles or impurities may cause equipment failures or performance degradation.

[0023] Embodiment:

[0024] Referring to Figures 1 - 4 , an emergency suspension chain includes an emergency chain, the emergency chain includes two groups of first links 1, and the two groups of first links 1 are connected by multiple groups of second links 3. There are two to twenty groups of second links 3, and here, we preferably choose seven groups. And at one end of each of the two groups of first links 1, a hanging buckle 2 is rotatably arranged, and an anti-detachment component is arranged on the hanging buckle 2. The materials of the first link 1, the second link 3, and the hanging buckle 2 are all preferably stainless steel, which can improve the anti-corrosion effect. When in use, by arranging the hanging buckles 2 at both ends of the emergency chain respectively, on the one hand, it can achieve quick installation and disassembly, improve the maintenance efficiency, and on the other hand, it can adapt to the replacement of dust plugs and chains for different vehicle models, improve the use effect, and there is a limiting rod 201 on the hanging buckle 2, which can prevent detachment and improve the reliability during use. Compared with steel wires, iron wires, and cable ties, this chain is convenient to carry and store, and does not occupy the spare parts storage space; when there is a risk of detachment of suspension parts such as the lower pipe system of the vehicle and components such as the upper roof of the vehicle, an emergency suspension chain can also be used in conjunction with other emergency spare parts to eliminate the risk of detachment.

[0025] Referring to Figure 1 、 Figure 2 AndFigure 4 A notch 301 is formed on the second link 3. The cross-sectional diameters of the first link 1 and the second link 3 are the same, ranging from 3 mm to 8 mm, preferably 3 mm, while the diameter of the buckle 2 ranges from 5 mm to 10 mm, preferably 5 mm. Among them, the width of the notch 301 is greater than the cross-sectional diameter of the second link 3, which facilitates connecting the second link 3 to the first link 1 and the sequential connection of multiple second links 3. And a stop rod 4 is slidably arranged in the notch 301, which can prevent the second link 3 from falling off during use and affecting the use effect. When in use, by forming the notch 301 on the second link 3, the second link 3 can be connected to the first link 1 and the sequential connection of multiple second links 3 is facilitated, which can quickly adjust the length of the emergency chain and improve the scope of use. Moreover, a stop rod 4 is slidably arranged at the notch 301, which can prevent the second link 3 from falling off during normal use and affecting normal work.

[0026] Refer to Figure 4 A limiting groove 302 is formed inside the second link 3. One end of the stop rod 4 is slidably arranged in the limiting groove 302, a groove 303 is formed on the inner wall of the notch 301, and the other end of the stop rod 4 is slidably arranged in the groove 303. And a spring 402 is arranged in the limiting groove 302, and the two ends of the spring 402 are respectively abutted against the limiting groove 302 and one end of the stop rod 4. When in use, by pulling the stop rod 4 to slide it into the limiting groove 302, the second link 3 or the first link 1 can be assembled and disassembled at this time. After the assembly and disassembly are completed, the pulling of the stop rod 4 is released. Under the elastic force of the spring 402, the stop rod 4 slides into the groove 303 to block the notch 301, improving the use safety.

[0027] Refer to Figure 4 A sliding groove communicating with the limiting groove 302 is formed on the second link 3. A push plate 401 is slidably arranged in the sliding groove, and one end of the push plate 401 extending into the limiting groove 302 is fixedly connected to the stop rod 4. When in use, by arranging the push plate 401 on the second link 3, it is convenient to drive the stop rod 4 to slide into the limiting groove 302 through the push plate 401, improving the use effect.

[0028] Refer to Figures 1 - 3 A rotating rod 101 is fixedly arranged at one end of the first link 1. A rotating hole is formed in the buckle 2, and the rotating rod 101 is rotatably arranged in the rotating hole. And a baffle 102 is fixedly arranged at the end of the rotating rod 101 far from the first link 1. When in use, by fixedly arranging the rotating rod 101 on the first link 1 and rotatably arranging the buckle 2 on the rotating rod 101, the torsion of the emergency chain can be reduced during use, improving the use effect.

[0029] Refer to Figures 1 - 3, the anti - detachment component can be limited by wire ties or bolts, etc. Here, we design the anti - detachment component as the limit rod 201. A rotation groove is provided on the hanging buckle 2, and a rotating shaft is fixedly arranged in the rotation groove. One end of the limit rod 201 is rotatably connected to the rotating shaft. A first card slot is provided at the other end of the limit rod 201, and a second card slot is provided on the hanging buckle 2. The first card slot is snap - connected to the second card slot, and a torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are respectively abutted against the limit rod 201 and the rotation groove. During use, when connecting, the limit rod 201 is pushed into the hanging buckle 2. After the connection with the dust plug and the mounting seat of the chain is completed, the pushing of the limit rod 201 is released. Under the elastic force of the torsion spring, the limit rod 201 resets, which can prevent the hanging buckle 2 from falling off during use and affecting normal use.
