[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution:
[0026] In this technical solution, a stable track fastener includes a fixed base 1. An adjusting pad is mounted on the upper surface of the fixed base 1. The adjusting pad includes a lower height adjusting pad 5, the upper end of which is fitted with a lower elastic pad 22. An iron pad 23 is mounted on the upper end of the lower elastic pad 22, and a track body 2 is mounted on the top of the iron pad 23. Mounting screw holes are provided between the two side walls of the track body 2 and the adjusting pad, and fasteners 4 are inserted into these mounting screw holes. The fasteners 4 include fastening screws. The fastening screw 6 and the anti-detachment screw 10 are provided. The fastening screw 6 is screwed with a fastening nut 7. The anti-detachment screw 10 is vertically installed at both ends of the fixed base 1. The bottom end of the fastening screw 6 is provided with an anti-detachment groove 8, and the anti-detachment screw 10 is screwed into the anti-detachment groove 8. The anti-detachment sleeve 9 is sleeved on the outside of the anti-detachment screw 10. Three limiting posts 17 are installed on the outer wall of the anti-detachment sleeve 9. The three limiting posts 17 are distributed in a triangle. The inner wall of each limiting post 17 is provided with a spiral groove 18 that cooperates with the fastening screw 6.
[0027] In this technical solution, an anti-loosening groove 8 is provided at the bottom end of the fastening screw 6, and the anti-loosening screw 10 is screwed in. Three limiting posts 17 installed on the anti-loosening cylinder 9 outside the anti-loosening screw 10 hold the fastening nut 7 in place, thereby limiting the fastening nut 7 in a circumferential manner. The spiral groove 18 on the limiting post 17 engages with the fastening screw 6, thereby limiting the anti-loosening cylinder 9 and the anti-loosening screw 10.
[0028] In some technical solutions, the inner wall of the anti-detachment cylinder 9 is provided with a reverse internal thread 19, and the outer part of the anti-detachment screw 10 that fits with the anti-detachment cylinder 9 is provided with a reverse external thread 20, and the reverse internal thread 19 and the reverse external thread 20 are matched.
[0029] In this technical solution, the external thread of the anti-detachment screw 10 is divided into two parts. The front part mates with the internal thread of the anti-detachment screw groove 8, and the rear part mates with the reverse internal thread 19 of the anti-detachment cylinder 9, thereby installing the anti-detachment cylinder 9 on the outside of the anti-detachment screw 10.
[0030] In some technical solutions, a turntable 21 is installed at the end of the anti-detachment screw 10, and a cross groove is opened on the outer wall of the turntable 21.
[0031] In this technical solution, the turntable 21 facilitates the rotation of the anti-loosening screw 10, and the cross groove facilitates operation with a screwdriver.
[0032] In some technical solutions, the outer wall of the fastening nut 7 is provided with an annular groove 11, and the end of the limiting post 17 is set in the annular groove 11.
[0033] In this technical solution, when the anti-loosening screw 10 is screwed into the anti-loosening screw groove 8, the anti-loosening cylinder 9 will rotate accordingly. When the limiting post 17 contacts the fastening nut 7, it can rotate in the annular rotating groove 11 until it contacts the inner wall of the annular rotating groove 11, thereby holding the fastening nut 7 in place and performing circumferential limiting.
[0034] In some technical solutions, a retaining ring 12 is fixedly installed on the upper outer end of the fastening screw 6, and an annular pressure plate 14, a spring 16 and an annular rubber sheet 15 are fitted on the circumferential surface of the fastening screw 6; the annular pressure plate 14 is located on the upper side of the retaining ring 12, the spring 16 is located on the upper side of the annular pressure plate 14, the annular rubber sheet 15 is located on the lower side of the retaining ring 12, and a compression block 13 is fixedly installed at the lower edge of the annular pressure plate 14.
[0035] In this technical solution, when the fastening screw 6 is rotated, the annular rubber sheet 15 slides upward due to the action of the screw hole. With further tightening, the annular rubber sheet 15 contacts the fixing ring 12. The annular rubber sheet 15 deforms due to the action of the fixing ring 12, sealing the screw hole. The spring 16 is located on the upper side of the annular pressure plate 14, causing the annular pressure plate 14 to be pressed downward due to the action of the spring 16. The compression block 13 is pressed downward due to the action of the annular pressure plate 14, causing the compression block 13 to further compress the edge of the annular rubber sheet 15, thereby improving the sealing effect. The annular pressure plate 14 is located on the upper side of the fixing ring 12, the spring 16 is located on the upper side of the annular pressure plate 14, and the annular rubber sheet 15 is located on the lower side of the fixing ring 12. The compression block 13 is fixedly installed at the lower edge of the annular pressure plate 14.
[0036] In some technical solutions, the lower end of the fastener 4 is equipped with an arc-shaped spring strip 3.
[0037] Working principle:
[0038] In use, the track body 2 is installed on the adjusting pad, the fastening screw 6 is inserted into the mounting screw hole, and then the fastening nut 7 is screwed onto the screw 6. Then the anti-detachment cylinder 9 is installed onto the anti-detachment screw 10. When the anti-detachment screw 10 is screwed into the anti-detachment screw groove 8, the spiral groove 18 on the limiting post 17 will engage with the external thread of the fastening screw 6 until the end of the limiting post 17 is placed in the annular groove 11 on the fastening nut 7, thus limiting the fastening nut 7.
