[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figs. 1-3An anti-vibration nut for high-speed trains includes a threaded tube 100 and a friction plate 200. A fixing plate 110 is fixedly connected to the outer side of the threaded tube 100, and a first spring 120 is fixedly connected to the lower side of the fixing plate 110. The lower side of the first spring 120 is fixedly connected to the friction plate 200, which is located outside the threaded tube 100. First limiting blocks 130 are fixedly connected to both the left and right sides of the threaded tube 100. Sliding grooves matching the first limiting blocks 130 are formed on both the left and right sides of the friction plate 200. After the threaded tube 100 is fixed, it contacts the fixing component through the friction plate 200, and then contacts the fixing component through the friction plate 200. The friction between the fixed parts improves the stability of the device. After the screw tube 100 contacts the bolt, it drives the fixing plate 110 to move downward. The downward movement of the fixing plate 110 drives the first spring 120 and the friction plate 200 to move downward and approach the fixed part. When the friction plate 200 contacts the fixed part, the fixed part vibrates and impacts the friction plate 200 and the screw tube 100. After a long period of impact, the screw tube 100 will loosen and gradually move away from the fixed part. However, the friction plate 200 remains in contact with the fixed part under the elastic force generated by the deformation of the first spring 120. Thus, the friction plate 200 maintains contact with the fixed part through contact with the fixed part. While limiting the movement, the friction force generated between the friction plate 200 and the fixing component reduces the possibility of loosening of the screw tube 100, improving the stability of the device. The friction plate 200 is limited by the first limiting block 130. The fixing component is limited by the cooperation of the screw tube 100, fixing plate 110, and first spring 120 with the friction plate 200. This also increases the friction between the device and the fixing component, reducing the possibility of loosening over time and improving the ease of use. A baffle tube 300 is fixedly connected to the outer side of the fixing plate 110, and a... The second limiting block 201 and the baffle tube 300 are provided with a sliding groove that matches the second limiting block 201. The baffle tube 300 is used to shield and protect the friction plate 200, and the second limiting block 201 is used to limit the friction plate 200. Multiple sets of metal plates 210 are fixedly connected to the lower side of the friction plate 200. The thickness of the metal plates 210 is 0.5-1mm. The metal plates 210 are used to increase the friction between the friction plate 200 and the fixing parts, thereby improving the stability of the device. Two sets of handles 103 are connected to the upper side of the screw tube 100. The handles 103 are used to facilitate the operator to rotate the screw tube 100.

[0023] Four sets of second springs 101 are fixedly connected to the lower side of the solenoid 100. Insert rods 102 are fixedly connected to the lower side of the second springs 101. The elastic force generated by the deformation of the second springs 101 drives the insert rods 102 to approach the fixing member. By setting the second springs 101 and insert rods 102, the friction between the friction plate 200 and the fixing member is increased, thereby improving the stability of the device. The lower side of the insert rods 102 is tapered, which increases the friction between the insert rods 102 and the fixing member.
