[0022] In practical implementation: such as Figures 1-4 As shown, a seismic connection component for a prefabricated cable trench in cold regions includes an outer tube 100, an inner tube 200, and a connection structure 300 for docking with the cable trench. There are two connection structures 300, which are positioned between the inner tube 200 and the outer tube 100 for quick docking and seismic protection. Each connection structure 300 includes a butt joint 310, a set of barbed rings 320, and a set of damping rings 330. The butt joint 310 is inserted into the interior of the outer tube 100. The barbed rings 320 are fixedly fitted onto the outside of the butt joint 310. The damping rings 330 are fitted onto the outside of the butt joint 310 and abut against the outside of the barbed rings 320. The damping rings 330 are fixedly installed inside the outer tube 100.

[0023] like Figure 4 As shown, the connecting structure 300 also includes a piston plate 340. A set of damping holes 341 are provided inside the piston plate 340. A support tube 342 is slidably connected to the outside of the piston plate 340. A hinge rod 343 is provided between the piston plate 340 and the connector 310, which is hinged to the outside of the connector 310. One end of the hinge rod 343 extends into the inside of the support tube 342.

[0024] During assembly and use, the user can align the two cable trenches, and then drive the cable trench with the inner tube 200 to the other cable trench, so that the inner tube 200 is inserted into the inner tube 100. After the movement is in place, the connector 310 can be driven to be inserted into the inner tube 100, so that the barb ring 320 abuts against a set of damping rings 330 in sequence until it is inserted into place. The damping rings 330 limit the barb ring 320, thereby completing the docking between the inner tube 200 and the outer tube 100, that is, completing the docking of the two cable trenches.

[0025] Subsequently in use, if the temperature difference is large in cold regions, heavy vehicle driving situation occurs vibration phenomenon, at this time the joint 310 will be affected by the movement of vibration, then can use the barbed ring 320 on the joint 310 will be in contact with the damping ring 330, using the damping ring 330 itself buffer deformation ability to offset part of the vibration, at the same time the joint 310 movement, piston plate 340 will follow the movement, at this time the gas in the support tube 342 will be extruded, then along the damping hole 341 slowly lead out, using the air pressure buffer, further offset part of the vibration, while the support tube 342 and the end of the articulated rod 343 are hingedly arranged, which can be laterally translated in a small amplitude during the vibration process, in combination with the longitudinal translation of the piston plate 340, in the movement process, using the above damping ring 330 shock absorption and air pressure shock absorption to gradually buffer, reduce the hard shock and the connection rupture damage phenomenon.

[0026] As shown in Figure 2 and Figure 3 , the inner tube 200 is slidably connected with two flat top pulleys 210, the opposite sides of the two flat top pulleys 210 are fixedly connected, the outer side of one flat top pulley 210 is slidably connected with a drive rod 211, one end of the drive rod 211 is inserted into the inner tube 200 and hingedly connected with one end of the support tube 342.

[0027] When the inner tube 200 and the outer tube 100 are connected, the corresponding flat top pulley 210 can be driven to move, as shown in Figure 2 , the inclined outer side can drive the drive rod 211 to move towards the inner wall of the outer tube 100, thereby driving the support tube 342 and the articulated rod 343, and assisting the joint 310 to connect with the outer tube 100.

[0028] As shown in Figure 4 , the support tube 342 is internally provided with a spring 344, one end of the spring 344 is fixedly connected with the outer side of the piston plate 340.

[0029] The spring 344 is arranged to flexibly support the piston plate 340, and after the vibration ends, it can assist the piston plate 340 to reset, reducing the large deviation between the two cable trenches caused by vibration.

[0030] As shown in Figure 2 and Figure 3 , the outer side of one flat top pulley 210 is slidably connected with two connecting rods 212, one end of the connecting rod 212 penetrates the inner tube 200 and is inserted into the inner tube 100.

[0031] After the inner tube 200 is inserted into the outer tube 100, the flat top cone disc 210 close to the butt joint rod 212 will drive the butt joint rod 212 to move and be inserted into the inner part of the outer tube 100, thus completing the quick connection between the inner tube 200 and the outer tube 100, that is, completing the quick butt joint between the two cable trenches.

[0032] As shown in Figure 2 , the inner part of the outer tube 100 is provided with a limiting block 110, and one end of the inner tube 200 is provided with a square hole 220 which is butted with the limiting block 110, and one side of the limiting block 110 is in contact with one side of a flat top cone disc 210.

[0033] After the butt joint of the two cable trenches, the inner tube 200 will be inserted into the inner part of the outer tube 100, then the limiting block 110 in the outer tube 100 will pass through the square hole 220 in the inner tube 200, thus achieving the pre-butt joint effect and reducing the vertical deviation and shaking between the outer tube 100 and the inner tube 200.

[0034] At the same time, the limiting block 110 will move in contact with the flat top cone disc 210 adjacent thereto.

[0035] As shown in Figure 2 and Figure 3 , one end of the butt joint rod 212 is provided with a rubber sleeve 213 which is in contact with the inner part of the outer tube 100.

[0036] The setting of the rubber sleeve 213 can make the butt joint rod 212 and the outer tube 100 be connected closely, and after the vibration phenomenon occurs, the deformation buffer effect of the rubber sleeve 213 itself can be used to weaken the vibration and improve the anti-vibration performance of the connection area.

[0038] It should be noted that the number of anti-vibration connecting components and the installation position can be selected according to the shape of the cable trench and the use demand.

[0039] In addition, it should be understood that although the present specification is described in the form of embodiments, not every embodiment contains only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and the skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments which can be understood by the skilled in the art.
