DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] See also Figure 1-2 A spring-bar type nylon baffle seat includes a concrete sleeper 1 and a rail body 2. A shock-absorbing plate 3 is fixedly connected to the bottom of the rail body 2. The shock-absorbing plate 3 is installed on the top of the concrete sleeper 1. Fixed plates 5 are installed on both sides of the top of the concrete sleeper 1 corresponding to the rail body 2 through bolts 4.
[0017] Vertical plates 6 are installed symmetrically on the top of the fixed plate 5, and a fixed shaft 7 is fixedly connected between the two vertical plates 6 on the same side. A torsion spring 8 is sleeved on the fixed shaft 7. One end of the torsion spring 8 is connected to a pressing plate 9, and the other end is inserted into the interior of the fixed plate 5. A metal spring 10 is fixedly connected to the side of the pressing plate 9 close to the rail body 2.
[0018] Specifically, a screw barrel 11 is fixedly connected to the bottom of the metal spring 10 corresponding to the top of the fixing plate 5, and a screw rod 12 is connected to the inner thread of the screw barrel 11. A through hole 13 is opened at the position corresponding to the screw rod 12 on the metal spring 10, and the top end of the screw rod 12 passes through the through hole 13 and is fixedly connected to the outside of the baffle 14.
[0019] Specifically, one end of the metal spring 10 is pressed onto the rail body 2 and a shock-absorbing pad 15 is fixedly connected to the contact surface. A shock-absorbing ring 16 is fixedly connected to the bottom of the baffle 14. The shock-absorbing pad 15 can provide a certain buffering and shock-absorbing effect from the contact surface between the metal spring 10 and the rail body 2, and also prevent the rigid contact from causing wear on the surface of the rail body 2. The shock-absorbing ring 16 can prevent the metal spring 10 from directly contacting the bottom of the baffle 14 during rotation, causing wear, and can also provide a certain buffering and shock-absorbing effect.
[0020] Specifically, the through opening 13 is a rectangular structure with arc-shaped surfaces at both ends. The baffle 14 is a circular plate with a diameter greater than the width of the through opening 13. The rectangular through opening 13 allows the metal dome 10 to rotate at a certain angle.
[0021] Specifically, a soft pad 17 is fixedly connected to the bevel groove on one side of the top of the pressing plate 9, and the soft pad 17 can facilitate the staff to press the pressing plate 9 downward.
[0022] This elastic strip type nylon baffle seat has a reasonable structural design and is easy to use. It uses elastic strips to fasten the rails, which can absorb and reduce the vibration force generated by some rails. It has extremely high torque resistance and can also ensure a good fixing effect on the rails, thereby fully meeting the use requirements of the rails.
[0023] During use, the fixing plate 5 can be positioned on the concrete sleeper 1 by means of the bolt 4. The metal spring 10 can be elastically compressed from above the rail body 2 by means of the elastic action of the torsion spring 8. After the screw 12 is inserted through the opening 13, it is screwed into the interior of the screw barrel 11. The baffle 14 is used to limit the metal spring 10 from above. Even when the rail body 2 moves, the torsion spring 8 can cooperate with the shock-absorbing plate 3, the shock-absorbing pad 15 and the shock-absorbing ring 16 to perform elastic buffering, thereby improving safety.
