[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0026] like Figures 1 to 8 As shown, this utility model provides a train track structure 200, which includes a plurality of steel rails 300 and a plurality of running track adjusting fasteners 100. The plurality of steel rails 300 are arranged in parallel in two groups, and the ends of the steel rails 300 in each group are spliced ​​together. The plurality of running track adjusting fasteners 100 are respectively engaged with the end splices of the plurality of steel rails 300 or with the middle section of the steel rails 300. The running track adjusting fastener 100 includes a bearing mechanism 10, a plurality of pressing mechanisms 20 and an adjusting mechanism 30. The plurality of pressing mechanisms 20 and adjusting mechanisms 30 are all mounted on the bearing mechanism 10, and the adjusting mechanism 30 is located between the bearing mechanism 10 and the pressing mechanism 20.

[0027] The load-bearing mechanism 10 includes a base plate 11 and several fixing bolts 12. The base plate 11 has several through-hole fixing bolts 111 at its four corners, and the fixing bolts 12 are respectively inserted into the fixing bolts 111 from top to bottom. During installation, the long fixing bolts 12 can be embedded deeply into the sleepers, so that the base plate 11, which bears the load, can be firmly installed, thereby ensuring the stability of the train track from the foundation.

[0028] The clamping mechanism 20 includes several clamping plates 21 and several clamping bolts 22. The base plate 11 also has several vertically penetrating first clamping screw holes 112, and each of the clamping plates 21 has a vertically penetrating second clamping screw hole 211. The clamping plates 21 are located above the base plate 11, with one side fastened to the rail 300. The clamping bolts 22 are sequentially inserted from top to bottom into the second clamping screw holes 211 and the first clamping screw holes 112. Under the limiting position of the clamping bolts 22, the clamping plates 21, in conjunction with the adjusting mechanism 30, can firmly fasten and fix the rail feet of the rail 300, allowing the rails 300 to be firmly spliced ​​and installed to form an integral train running track.

[0029] The adjustment mechanism 30 includes an adjustment plate 31 and an adjustment bolt 32. The adjustment plate 31 has several third clamping screw holes 311 and an adjustment screw hole 312. The adjustment plate 31 is located between the base plate 11 and the clamping plate 21, and the clamping bolt 22 passes through the third clamping screw hole 311. The adjustment bolt 32 passes through the adjustment screw hole 312 from top to bottom, and the lower end of the adjustment bolt 32 abuts against the top of the base plate 11. The adjustment bolts 32 on both sides of the adjustment plate 31 can be turned to adjust the relative height of the two sides of the adjustment plate 31, thereby keeping the two sides of the rail 300 supported on the adjustment plate 31 horizontally balanced. This adjustment method is easy and simple, and the adjustment accuracy is also extremely high.

[0030] Specifically, in this embodiment, the adjusting plate 31 is further provided with a locking groove 313, and an insulating pad 314 is fitted into the locking groove 313. The thickness of the insulating pad 314 is greater than the side edge height of one side of the locking groove 313 and less than the side edge height of the other side of the locking groove 313. The insulating pad 314 can further protect the safety of the rail 300 in use.

[0031] The track adjusting fastener 100 also includes a connecting mechanism 40, which comprises several connecting plates 41 and connecting bolts 42. Each of the connecting plates 41 has several through-holes 411 on both sides. These connecting plates 41 are respectively fitted to the joints of two rails 300. The connecting bolts 42 pass through the connecting holes 411 of the connecting plates 41 and the ends of the rails 300. The connecting mechanism 40, through the cooperation of the connecting plates 41 and the connecting bolts 42, can connect two rails 300 together, making the splicing between the rails 300 more secure.

[0032] Specifically, in this embodiment, the connecting mechanism 40 further includes an auxiliary fastening bolt 43, and one end of the connecting plate 41 is also provided with an auxiliary fastening screw hole 412. The auxiliary fastening screw hole 412 communicates with the connecting hole 411, and the auxiliary fastening bolt 43 passes through the auxiliary fastening screw hole 412 with one end extending into the connecting hole 411 and abutting against the side of the connecting bolt 42. The auxiliary fastening bolt 43 can enhance the tightness of the connecting bolt 42 and prevent the connecting bolt 42 from loosening due to long-term vibration, ultimately affecting the overall strength of the track.

[0033] The travel track adjusting fastener 100 also includes a flattening mechanism 50, which includes a pressing plate 51, a plurality of mounting bolts 52, and flattening bolts 53. The base plate 11 has a plurality of first mounting holes 113 on one side, and the adjusting plate 31 has a plurality of first flattening holes 315 on one side. The pressing plate 51 has a plurality of second mounting holes 511 and second flattening holes 512 that pass through both sides. The pressing plate 51 is located on one side of the base plate 11 and the adjusting plate 31, with the second mounting holes 511 corresponding to the first mounting holes 113, and the second flattening holes 512 corresponding to the first flattening holes 315. The second flattening holes 512 are vertical elongated through holes. The mounting bolts 52 are sequentially inserted into the second mounting holes 511 and the first mounting holes 113, and the flattening bolts 53 are sequentially inserted into the second flattening holes 512 and the first flattening holes 315.

[0034] When the train track is installed on an uneven foundation or when the rail 300 becomes abnormally skewed after prolonged use, the rail 300 can be finely adjusted by simply tightening the flattening bolts 53 on each fastener in sequence, thus correcting the skewed rail 300 back to the standard position. This adjustment method does not require disassembling and adjusting the track fasteners, saving both time and effort.

[0035] In summary, the beneficial effects of this utility model's running track adjusting fastener 100 and train track structure 200 are as follows: By designing the running track adjusting fastener 100 with an adjusting mechanism 30, the rails 300 can be freely and accurately leveled even when the train track is installed on uneven ground. After long-term operation, the posture of the rails 300 can be adjusted more easily to address issues such as rail skewing. The connecting mechanism 40 in the fastener can firmly connect two spliced ​​rails 300, not only achieving a better seamless splicing effect between the rails 300 but also further improving the overall stability of the running track. The flattening mechanism 50 allows the fastener to easily and conveniently adjust the overall balance of the rails 300, thereby further improving the problem of rail 300 deviation. This utility model is highly practical and has significant promotional value.

[0036] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
